A GiAnt ExpEriEncE for SmAll SpAcES ®

The revolutionary AS3X® (Artificial Stabilization - 3 aXis) System from Horizon Hobby is advancing the performance and capability of ultra micro aircraft unlike anything that’s come before. And if you’ve tried any of the great ultra micro aircraft with AS3X technology, then the amazing performance probably has you looking at every place you go as a possible flying site. That’s because the AS3X System makes it easier to fly in light wind and turbulence, so you can fly in small spaces but still get a Giant-Scale experience.

UMX Sbach 342 3D BNF Basic

(EFLU4950)

The UMX™ Sbach® 342 3D BNF Basic—designed by Mike McConville—is specially engineered to provide precision aerobatic and extreme 3D maneuverability.

Whether you want to fly smooth scale maneuvers or wild 3D moves, its AS3X system is specially tuned to give you the sense of authority and stability you’d expect with an expertly tuned Giant-Scale airplane.

UMX MiG 15 DF BNF (EFLU1680) The UMX MiG 15 DF is a breakthrough in ultra micro electric ducted fan technology and delivers scorching performance. Its AS3X System is specially tuned to offer slow flight that’s rock solid and the kind of control to perform high-speed passes or enormous loops as super smooth as a Giant-Scale jet.

UMX Carbon Cub SS BNF (EFLU1180) The UMX Carbon Cub SS offers performance that’s an escape from the ordinary. Equipped with the AS3X System, this versatile Cub is extremely friendly and rock solid at all times, which makes it ideal for use as a tug with the UMX ASK-21 or as a float plane when fitted with the optional UMX Carbon Cub SS Float Set (EFLUA1190).

UMX ASK-21 BNF (EFLU1280) The UMX ASK-21 is a fully functional unpowered scale RC sailplane, equipped with a remote tow hook release so you can aerotow with another ultra micro aircraft like the UMX Carbon Cub SS. The onboard AS3X System offers solid control and smooth handling that you’ll especially appreciate during those critical moments while on tow or Hi-Start line.

SERIOUS FUN.™

Micro size. True jet looks.

In Tx-R and RTF versions.

The buzz on the F-86 Sabre started the moment it hit the web and hasn’t stopped since. Pilots rave about the size, the performance, the component quality and, of course, the Tx-R technology behind it. And now that there’s an RTF version, they’ll have even more to talk about.

The real-life looks and performance package are identical. For power and speed, there’s a brushless motor and 30 mm HyperFlow fan matched to a stand-alone ESC and LiPo flight pack. And for flawless reception and response, you get a 2.4GHz SLT micro receiver and three ultra-micro digital servos.

So really, your choices are these: get the Tx-R, and fly with the transmitter you prefer – or go with the RTF, and get a Tactic TTX402 system along with everything else.

™

The F-86 Tx-R is just that: a jet that’s ready for a transmitter.

Add the AnyLink, and you can fly the F-86 and all other Tx-R aircraft with the flight transmitter you like best: yours!

For more information on the Tactic AnyLink, transmitter compatibility and requirements, visit Tx-Ready.com. Tx-R, SLT and AnyLink are trademarks of Hobbico®, Inc.

But don’t wait, because the F-86 is going fast! ®

T

o say I’m excited about our November 2012 issue of RC Sport Flyer (RC-SF) would be an understatement. This issue marks a paradigm shift for the magazine’s content and presentation. Going forward, RC-SF will present content to you in a more in-depth and focused way than we ever have. You’ll not only be getting content in a more in-depth way, but with as much technical information as we can possibly scour from our sources: Internet, distributors, manufacturers, designers, pilots and other experts. It won’t be easy, but it will be fun, and I will tell you that all of us at RC-SF have a true passion for the hobby. Therefore, we see it as our mission (if you can call it such) to give you the content we feel you want and need to make the hobby more enjoyable for you.

Over the last 17 plus years we’ve had many opportunities to share great content with you.

We’ve been blessed by having great contributing editors, pilots, designers, distributors, manufacturers and others who give us true insights into the hobby. And, we’ve shared those insights even when we weren’t sure we could see the future clearly. I remember flying my first electric with Rob Smith in the 1980s. At the time I thought electric-powered airplanes would never really take off. Then when Sal DeFrancisco sent me a Blues 400 LMR glider in the early 1990s, I knew as sure as the sun would set that day that electric-powered airplanes were the future of the hobby. That’s why this magazine was formerly named Quiet Flyer. And, electrics really did take off. Then too, when Charlie Wang of Thunder Power introduced Li-Ion batteries to the hobby I was simply blown away by their performance—nope, I did not see them vent with fire. What I did see was the future of electric-powered airplanes, helicopters and gliders climbing out, with nowhere to go but straight up. It was the same watching 3D-type airplanes catch on in the hobby.

Heck, for a while we even produced the magazine 3D Flyer, but then 3D flying became the norm, so that magazine was merged into this one. We even had the good fortune in 2005 to publish an article on a 2.4-GHz radio system that a group of guys in the Midwest had designed. I can tell you that article really caught the attention of some people in the industry. Honestly, we knew the technology was possible because it had been used in the communications industry for years. However, it had not yet been implemented into RC hardware. Well, that is history now, and the industry has embraced 2.4-GHz spread spectrum systems, much to the delight of RC pilots the world over.

All that behind us, this issue and its cover photo just turn me on! I mean TURNS ME ON, because it underscore a real paradigm shift in the industry—a shift that is now embracing telemetry systems in many of the best radio systems money can buy, and surprisingly, some of them are not expensive and offer telemetry technology that aviation modelers everywhere have wanted for years and years.

What I think is so earth-shattering about telemetry is that it is absolutely going to change the way our RC airplanes are designed, built, flown and used in competitions. For example, if you are a pattern pilot you will get data from your airplane’s telemetry system that tells you how fast its uplines and downlines were flown. You’ll be able to look at the flight in 3D on your computer after it has been flown to see if the patterns were good or bad. IMAC pilots will be able to do the same with their airplanes. You’ll now be able to see how square you can fly loops or how straight your airplane’s knife-edge pass was flown. Hey, if you are helicopter pilot you’ll be able to get real-time rpm data, with motor current if you want. You may also want to know the battery voltage or the fuel level. It is all going to be possible with telemetry.

As a glider/sailplane/electric pilot I’m so “pumped up” that I can’t wait for the next flying season. Because now I can know exactly how high my scale sailplane is, where it is in relation to me by GPS data, what its airspeed is and what its rate of climb/sink is at any point in time. I’ll be able to truly set the airplane’s decalage and center of gravity position and optimize my model’s performance to the Nth degree. And when you think of it, just knowing what the battery voltage is could save me—and you too—from crashing a model because of a low battery condition.

Man, I’m just scratching the surface here with what telemetry is going to give back to the hobby. I’ll buy you a subscription or even 10 if I’m wrong. In the case of telemetry systems, though, I can feel it in my bones. It is going to happen, and I can’t wait to see how the industry will embrace it and how we’ll all benefit.

Till next month, check your altimeters, and enjoy your new telemetry system.

Don’t Fly with Fakes Fly with the NEW Spektrum™ AR400 – Original DSMX® Technology for just $29.99 Imitation leather. Imitation diamonds. Imitation Swiss watches.

All cost less than the real thing, but you get what you pay for: a fake of inferior quality. Cheap imitations of Spektrum equipment are no different. You risk more than the money you saved, and you’ll have about as much luck getting service after the sale as you would from the guy selling watches on the corner.

For just $29.99, the full-range, 4-channel Spektrum AR400 receiver gives you all the benefits of genuine DSMX technology, plus the long–range signal clarity of an active amplified antenna. Because the AR400 is original Spektrum equipment, you’ll also enjoy the unbeatable service and support of Horizon Hobby. And that’s one thing nobody can imitate.

Don’t fly a fake. Stick with the original.

very year, RC’s best-selling flight simulator just keeps getting better. RealFlight 6.5 is no exception, offering new ease and realism everywhere you look. One of the biggest contributors to realism is TrueView™ lighting, which makes everything onscreen look as it would on a sunny day at the field. It offers the visual impact of natural sunlight, resulting in brighter, truer colors, sharper contrasts and details that stand out as never before. Light reflects from the ground to the underside of a wing, and canopies are clear and crisply defined, just as they would be on full-size aircraft. Another addition is the welcome screen, which appears once RealFlight 6.5 is launched. Besides displaying a rotating tip of the day, the welcome screen offers fast, easy ways to select your aircraft, flying site, predetermined aircraft/flying site combinations, helpful training videos and recent aircraft or flying site choices.

In addition to everything that’s new, RealFlight 6.5 also offers all of the features and functions that have made RealFlight the bestselling simulator for over a decade.

Enhancements include: • New graphics settings & controller calibration screens: allows pilots to modify settings with a simple slider bar and see the results immediately • NavGuide™ customizing options: new editing tools allow pilots to quickly add, delete or modify existing settings, or go back to the factory defaults • Smart binocular vision: activates automatically when the aircraft exceeds a preset difference and fades away when it’s no longer needed.

J

R kicks up your “smack” potential with the JR NEX E6-550. Even when equipped with a 5000-mAh 6S Li-Po flight battery, the E6-550 is the lightest 550-size helicopter in its class. Practical and efficient, the E6-550 gives you many of the practical benefits smaller electric helis enjoy but the 3D performance many experts compare to a 600- or 700-class helicopter. The practical side is that instead of needing two 6S packs to fly a 12S powered helicopter once, you can fly the JR NEX E6-550 twice doing 3D and big maneuvers you like with the larger machines. That’s convenience packaged the only way JR knows how—with performance.

Like most large-class electric helicopters, the E6-550 is equipped with a torque-tube

driven tail with dual-bearing support. You can buy the JR E6-550 as just a kit with carbon main and tail rotor-blades, but you can also get the JR E6-550 combo package complete with a high-speed brushless outrunner motor, fully programmed and wired 75-amp ESC, the easy-to-use JR triple axis gyros system (TAGS01) and all-new JR digital servos designed specifically for the demands of flybarless cyclic control. The JR NEX E6-550 gets you ready for an RC helicopter experience that’s small helicopter fun with big helicopter performance.

Visalia Aerotow

2012

Superb Scale Soaring at a Super Site

F

or probably the last 10 years, the RC scale soaring pilots from California have been encouraging me to come to Visalia to join them for a weekend of aerotowing largescale gliders. This past October I finally did just that over the weekend of October 19, 20 and 21. It was a weekend of taking in the excellent weather, enjoying lots of conversation with a great bunch of guys and watching/photographing some of the most beautiful large-scale gliders you’ll see anywhere.

Axel scale pilots are very popular with the scale glider pilots. Here you see a 1/2-scale pilot sitting in Dan’s Ka-6. FMI on Axel pilots go to: axels-scale-pilots.de.

RC SPORT FLYER — november 2012

Visalia Aerotow 2012 Dan Troxell’s 1/2-scale Ka-6 glider is being pulled into the air at Visalia. The model sports a 295-in. wingspan and weighs about 50 lb ready to fly.

Dan’s Ka-6 uses a bright color scheme, which help with visibility at high altitudes. Most scale glider pilots want their aircraft to look like the full-scale.

We include this photo because many of the pilots at Visalia are still flying 72-MHz systems because their models get very high and sometimes far away.

Where

Visalia California is about three hours from San Francisco and the same from Los Angeles when traveling by car. It is located in the heart of the San Joaquin Valley—a rich agricultural area that is drenched in sunshine most of the year.

The Visalia soaring site is just about five miles out of the downtown area to the northwest. It is easy to find. Additionally, the Visalia soaring site is located near lots of quality accommodations and some excellent restaurants. The Visalia site is most known for hosting the Fall Soaring Festival, which often draws more than 300 pilots to compete in a huge thermal duration contest. However, it also hosts two superb aerotow events and even a couple of float fly events each year.

There are actually two parts to the Visalia RC airfield: the thermal duration side and the aerotow side of the field, which is also flood-able for the float fly events. The aerotow side is simply to die for. It is flat as a pancake, with mown grass that Axel is busy watching the crowd at Visalia and waiting for his next tow to altitude. If you order one of these guys be prepared to wait a while for delivery.

How it Works

This superb soaring site hosts two exceptional aerotow events each year.

The spearhead behind the aerotow events seems to be the contest director, Chris Pratt. And, let me

tell you, Chris puts on an excellent event from the pilots’ meeting to the aircraft towing of gliders. Heck, there were even donuts being handed out to pilots and spectators when I showed up. How cool is that!

What I really enjoyed about the way this event was run was the laidback approach to management. Make no mistake, Chris held a very good pilots’ meeting, and after it was over

Mark Foster was flying his huge 1/2.5 scale Nimbus 4. It flies on a wingspan that is 415 inches. The wings are carbon reinforced for the strength needed for the aspect ratio. FMI: icare-rc.com.

everyone knew what was expected of them in terms of queuing up to fly. As a result, the tow pilots managed the queue so that when anyone needed a tow for their sailplane or glider, the tugs and their pilots were at the ready, which meant lots and lots of tows and airtime for the aircraft. The line ran smoothly all day, every day.

Here is another one of Mark’s gliders. It is the ASH-25, which was modeled in 1/3 scale. Again this model is an outstanding flyer because of its high aspect ratio and low drag airframe.

Dennis Brandt’s ASH-31Mi is equipped with a large-scale wing wheel that it uses during ground handling. It is removed for flight. You can find these at icare-rc.com too.

Dennis is shown with his ASH-31Mi. Notice the wing droop while the model sits on the ground. It will all go away once the model is in flight and the aircraft is loaded.

The ASH-31Mi is coming in for a landing with its flaps and spoilers deployed. I was given a chance to fly this model and I can assure you it is a superb flying machine that indicates lift very well.

This model is a 1/3.5-scale ASW-27. It flies on a foam core wing that is sheeting in wood.

The fuselage is composite. The wingspan is 168 inches.

Dean Gradwell was flying this Antares, which is built by Baudis and distributed by Soaring USA. It is 1/3-scale and has a wingspan of 262 inches and weights about 420 oz. FMI: soaringusa.com or dean@xcsoaring.com.

Sailplanes & Gliders

Another highlight of the event for me was the number of vintage and modern aircraft being shown and flown. While I love the “glass slippers” and their sleek, high-performance airframes, there is nothing like seeing a huge vintage glider soaring overheard. As you’ll see in the photos, there were many interesting models in attendance.

The largest sailplane by far was Mark Foster’s 10.5-m-wingspan Nimbus 4. However, Dan Troxel was 32

One of my favorites was Bill Curry’s 1/4-scale SZD 8 glider, which had a 160-in. wingspan. Bill scratch-built his model, using a set of RC Sport Flyer plans for the needed drawings and documentation. Ken Kaye showed off a 6-m-wingspan K8b model he’d purchased from Phoenix Model. He had to do some rework on it to turn it into the outstanding glider he was flying, though. No matter—this model was a joy to watch soaring the skies

Dean Gradwell’s Antares is shown here coming in for a landing. One thing about these large-scale gliders is that they fly like the full-scale machines, so they use spoilers and flaps for landing, and they have a retractable gear.

This 1/3.5-scale DG-600 is shown with the landing gear down and spoilers out for landing. Notice that the flaps are opened to about 20 degrees as well to slow it down.

This Salto is a great flyer. It has scale spoilers in the wings’ trailing edges and flies on a 157-in. wingspan. It is an all composite glider and very aerobatic. FMI: icare-rc.com.

3rd Italian Scale Vintage Glider Meet A Gathering where Old is New!

RC SPORT FLYER — november 2012

3rd Italian Scale Vintage Glider Meet

I

nterest in building and flying RC vintage gliders is exploding in Italy. Many modelers find that modern composite gliders look too similar to each other, but vintage sailplanes, on the other hand, are very distinctive. The full-scale aircraft the models copy were all designed and built differently because the designers were searching for better performance using the empirical method. Consequently, the fuselages, wings, empennages and even canopy always had a different design and look. Also, many of the vintage gliders were built at home or in small shops.

It is therefore not surprising that vintage gliders are challenging to replicate. Fortunately, though, many model glider designers are tackling This 1930s vintage Libratore Bonomi BS.17 Allievo CantĂš is an excellent example of what vintage gliders represent.

The Bowlus BA-100 Baby Albatross is a vintage glider from a 1938 design. It is a classic vintage machine.

the challenge of drawing plans and building them head on. As a result, RC glider meets for these creations are starting to pop up all over Europe, with some in the U.S. as well.

Most RC glider meets include both vintage and modern gliders, either for slope soaring or aerotowing. The model glider club in Cremona, the home of the famous violin maker Stradivarius, is called the Gruppo Aeromodellistico Cremonese. Many of their members fly vintage gliders. The club just held its third annual scale vintage glider aerotow meet. What made it distinctive was that only vintage gliders were allowed to be flown—a

change from most meets.

The club has 33 members with an average age of 50. However, the age range of the club members is 11 to 85. They are led by Marco Pattoni and Tullio Facchin.

The airfield consists of two parallel grass runways measuring 650 x 175 ft (200 x 25 m), an area for model flight preparation and a wide parking area 125 ft (40 m) from the runways. It is a near-perfect site for aerotowing gliders and sailplanes.

On Sunday, October 14, 2012, the third Scale Vintage Glider Meet took place at the airfield of Annicco, on the outskirts of Cremona. A total of 37 model builders/pilots, six tow

pilots and about 50 scale vintage gliders took part.

There was a significant variety of sailplanes being displayed and flown. Pilots brought their aircraft from many parts of the world. Their

models were copied after famous gliders by prominent designers such as Hans Jakob, Slingsby, Schweizer, Wolf Hirth and George Mueller. As expected, almost a third of the scale models were of German designs,

such as the Minimoa, Kranich IIB, Rhönsperber, Wolf, Goppingen, Rhönbussard, Grunau Baby, Habicht, Reiher, Ka3, Ka6, Ka8 and Bergfalke.

Polish designs included the Orlik II, SZD Bocian and SZD Foka. Three Italian sailplanes attended: the Sparviero, the Turbine of Teichfuss and the Allievo Cantu of Bonomi Silva. A Schweizer SGS 1-26E, a Baby Albatross and a Super Albatross represented the United States designs. Other scale models rounded out the meet like the Harbinger, the Musger MG19A, the Kirby Kite, the Macka and the Stakhanovtz. Sorry if I forgot any!

Although the event had a cloudy beginning, the skies cleared in the afternoon, which offered excellent thermal conditions and long-lasting flights. Competition was not the goal of the meet. Rather, it was just a Here is an example of the KBI-14 Macka aerobatic glider, which was a 1959 design that was built from plans.

Fuselages: Part 2 The Great Planes® Super Sportster 60

I

f you’ve been following my “Building Model Airplanes” series for RC Sport Flyer magazine, you’ve watched the progress of five different airplanes as they hit my workbench and came under the camera. The five tail sections were followed by three sets of wings. Two additional sets of wing are still to come, but I figured that both you and I needed a break from sticks and ribs. The slab-sided fuselage for the Great Planes Super Sportster 60 was framed up in the October 2012 issue, and the follow-

Construction of the Great Planes Super Sportster 60 fuselage began in the October 2012 issue of RC Sport Flyer, taken to the point where the basic assembly was complete and only the nose and tail blocks were still to come.

1 Drilling through the chin block for the nose gear is easiest if you drill down through the nose gear mounting lugs on the engine mount from the top side of the model.

Slide the nose gear through the chin block and into the mounting lugs on the engine mount. Then use a pencil to mark the outline of the recess that needs to be cut to accommodate the gear’s coil spring as it travels approximately 1/2 in. from side to side.

2 up is here for you now. I promised you that a few cool methods of dealing with fuselage block would happen, and so they shall—right now.

The Sportster 60 can be built with conventional landing gear—a taildragger—or with tricycle gear. I chose the “trike” version because the other four airplanes in this build series were all taildraggers.

Before installing the nose blocks on the Super Sportster 60, nose gear mounting must be addressed. The Great Planes engine mount that comes with the Sportster kit has mounting lugs on its upper and lower frames to hold a nose gear. The gear will slip through the wooden bottom (chin) block and go into these two 42

4 Locating the mounting hole positions on the engine mounting beams is simplified if you use the Dead Center Hole Locator from Great Planes. This springloaded tool uses a 1/6-in. drill bit to make perfectly centered starter holes in all kinds of modeling situations.

Position the engine on the mounting beams and insert the cone-shaped tip of the tool into one of the engine’s mounting lugs. Press down and turn the upper knurled fitting to drill a starter hole into the beam. Use the tool to drill the remaining three starter holes, and finish by drilling a 1/8-in. hole through the beams at the four starter marks. Screw the engine down with four #8 sheet-metal screws.

mounting lugs. There, it will be secured by a 5/32-in. wheel collar and the steering arm, which is more correctly called a tiller.

Getting the hole through the chin block in the correct position is easier than you might think. Instead

Use the bar sander with coarse sandpaper to sand the side strips flush with the tops of the two bulkheads and firewall. Work as neatly as possible to prevent getting sanding dust inside the engine. I didn’t, but you should probably protect the engine with a plastic bag or a layer of kitchen wrap.

of poking a dozen holes through the chin to find the mounting lug, just use a long 5/32-in. drill or a piece of sharpened-brass tubing to go through the mountings lugs from the top, passing downward through the chin block. When the hole is drilled, slide

the nose gear through the hole and into the mounting lugs until the nose gear’s coil spring touches the chin block.

With the nose gear inserted and the coil facing the rear of the fuselage’s tail, rotate the gear

9 You must add the forward deck block and the two side blocks to the fuselage, followed by any scraps needed to locate the plywood nose ring in its proper position. I used CA glue to fasten the blocks into position.

Tack-glue three or four 1/16-in. scraps between the nose ring and spinner backplate before gluing the nose ring to the fuselage. This will ensure that the clearance between the spinner and nose of the finished model is set properly.

Use the razor plane to shave the deck block, side strips, side blocks and chin block to blend into the fuselage sides and nose ring. The engine won’t be needed after the muffler and carburetor clearances have been cut, so this is a good time to remove the engine.

10

Use a cutting bit on a rotary tool to open the recess that you previously marked for the nose gear coil. If you don’t have a rotary tool, you can do the job with a hobby knife and a #11 blade by making a series of puncture slices all around the pencil mark. It’s a bit tedious, but it works.

11 RC-SF.COM

43

Sand the inside of the recess smooth with a drum sander on the rotary tool. Wrapping sandpaper around a wooden dowel or a length of brass tubing is a good alternative if you don’t have a rotary tool or a round Perma-Grit tool.

12

Check the fit of the nose gear coil inside the recess, being sure that the recess will allow the coil to travel approximately 1/2 in. each way to the right and left.

With the engine and nose gear wire removed, use the bar sander to final-shape the forward fuselage. Sand until you think it’s perfect, then get some sleep and look at your work the next day— then sand it again.

14 approximately 1/2 in. to the right, then to the left. Use a soft pencil to mark the location of the coil in both positions, then continue the pencil marking to outline the coil throughout this side-to-side travel.

Remove the nose gear wire.

The forward upper deck and two nose blocks go onto the model next, but first you must mount the engine. This is an important step, and you want it done correctly, so here’s a handy tool to do the job: the Dead Center Hole Locator from Great Planes. This tool is based on an 1/8-in.-diameter brass tube with a knurled grip on the top and a cone-shaped fitting on the bottom. A 1/16-in. drill passes through the tube, and its shank extends from the top of the brass tube. Another knurled fitting is at the top of the drill with a coil spring between the two knurled fittings. When you press down on the upper fitting—the one attached to the drill—the drill tip goes downward and passes through the cone-shaped fitting at the base of the tube.

Using the Dead Center Hole Locator is a piece of cake. Just get the engine into the correct position over the engine mount’s beams, then insert the cone-shaped fitting into one of the engine mounting lugs.

The cone is round and will center 44

Use scraps of wood the thickness of the horizontal stabilizer and vertical fin to create mounting shims for the tail blocks. Laminate strips of 1/32-in. balsa over each of these to simulate the thickness of the MonoKote that will cover the tail surfaces when they are installed.

itself in the hole. Now hold the tool upright, grasping it by the knurled fitting on top of the brass tube, and press down on the upper knurled fitting, turning it clockwise with your other hand to drill a starter hole in the engine mount beam. Being careful not to move the engine, use the Dead Center tool to drill the three remaining starter holes.

Now that the engine mounting holes are marked and started, drill 1/8-in. pilot holes all the way through the mounting beams at all four locations. Finish the mounting holes by running a #8 1-in. sheet-metal screw into each of the four pilot holes. Remove the screws, and the mount is ready to receive the engine.

Simple? Good. Now install the engine with the four sheet-metal screws.

With the engine mounted, it should be easy to determine and mark the best possible positions for the plastic sleeve that will house the throttle rod, and for the two 1/4-in. holes that will allow the tank-tocarburetor (feed) and tank-to-muffler (pressure) fuel lines to pass through the firewall. Mark these three locations, but don’t try to drill them

15 yet, especially not with the engine still mounted.

Cover the engine with a plastic bag or kitchen wrap to keep it dust free, then use a razor plane and a sanding bar with coarse sandpaper to prepare the tops of the fuselage side pieces to receive the forward upper deck block. Be sure the forward edge of the block clears the engine cylinder and muffler, then glue it down over the side strips with gapfilling CA or five-minute epoxy.

Now you can install the two side blocks over the chin block and ahead of the firewall. Be sure to let the tail ends of these side blocks extend outward from the fuselage sides by at least 1/8 in. Doing so will let you sand a graceful curve into the blocks, rather than an abrupt one. Install the blocks with gap-filling CA or fiveminute epoxy.

The kit comes with a 1/16-in. plywood nose ring, and this should be tack-glued onto the back of your spinner’s backplate. Use a few scraps of 1/16-in. scrap balsa or plywood between the ring and backplate, with a tiny drop of gap-filling CA on each side of the scraps to hold them between the two components.

Be sure the backplate is perfectly centered over the nose ring. The best visual checkpoint is the outer

Fuselages: Part 2 Tack-glue the scraps over the stabilizer saddle, making absolutely certain that the shim for the vertical fin is in perfect alignment with the fuselage centerline and perfectly centered between the fuselage sides.

Glue the front faces of the tail blocks securely to the rear bulkhead with gap-filling CA or five-minute epoxy, but only tack-glue the blocks to the scrap shims between and under them.

16

17

If you want to add scallops between the stringers on your Super Sportster’s turtle deck, cut lengths of 1/4-in. scrap balsa to fit between each pair of stringers.

Smaller scraps can be glued between the stringers at the rear end of the turtle deck. Handling the wood scraps with CA applied can get ugly, so try piercing each scrap with a hobby blade to let you handle and position it without getting your fingers stuck.

18

19

Here’s my Super Sportster 60’s rear section with the tail blocks and rear scallop scraps glued into place and ready to plane and sand to the necessary shape.

Use a razor plane to roughshape the tail blocks. Get them as close to their final shape as possible without gouging the blocks or cutting them too deeply.

20 diameter of the backplate; looking from the front of the backplate, you should just be able to see the outline of the ring all the way around.

When the CA is dry, slide the backplate over the engine’s crankshaft to see if the nose ring firmly contacts the chin and side blocks. If you can’t get the backplate fully seated against the crankshaft, sand the chin and side blocks until you can. On the other hand, if the nose ring doesn’t quite come into contact with the side and chin blocks, as was the case with my Super Sportster’s older Enya 60TV, you can use balsa scraps to fill any gaps between the ring and blocks. When you’re satisfied that the spinner ring cannot be fitted any better than it is, attach it to the chin and side blocks (or to the balsa scraps in between) with five-minute epoxy.

21

Remove the spinner backplate from the engine by cutting through the 1/16-in. scraps you tack-glued between the backplate and nose ring. If you didn’t use too much CA, you can probably use a small slot screwdriver to pop the scraps free from behind the backplate. You’ll most likely have to sand the scraps away from the nose ring, and if you do, you’ll find that coarse paper on the bar sander is best for the task.

Now unscrew the four sheet-metal screws and remove the engine from the mount. For now, keep the engine mount attached to the firewall.

Use a razor plane to shave the upper deck block, the two upper side strips, two side blocks and the chin block. They don’t have to be finished yet, but knock them down sufficiently so that sanding them to blend into each other will not be a back-breaker.

You can use a Zona saw to roughcut the areas of the blocks near the plywood nose ring, but use the plane to get those graceful curves.

When the front end of the fuselage is rough-shaped, use a rotary tool or a hobby knife to cut the chin block inside the pencil outline you made for the nose gear coil. The hole should be sizable enough to let the gear coil pass through it and travel from side to side, but it shouldn’t be unnecessarily large. When you have the hole clearance you need, use a drum sander on the rotary tool, a 1/2-in. round Perma-Grit tool or a piece of adhesive-backed sandpaper wrapped around a wooden dowel to smoothly finish the inside surface of the coil recess. Slip the nose gear into the mounting lugs once again, and check the gear coil for adequate side-to-side travel inside the recess.

RC-SF.COM

45

Sand the blocks and scallop scraps for the final time with coarse sandpaper on a bar sander.

22

A good eye can do the trick, but if you need a little help to ensure that that the round recess in each of your scallops is cut to the same depth, try laying a length of masking tape around the scallop scraps behind the canopy bulkhead.

23

Use a round Perma-Grit tool or the sandpaper-around-a-dowel substitute to sand the rounds into each scallop scrap. Work slowly to get perfectly even recesses and to prevent nicking the stringers with the tool.

These scallops look great under the model’s covering.

24 You can finish shaping the front end now or wait until the tail section of the fuselage is rough-shaped and do the whole fuselage component at once. If you choose to finish the front end now, get out the bar sander with the coarse sandpaper and blend the upper deck, the upper side strips, side blocks and chin block into the fuselage sides and nose ring. Be careful about sanding close to the nose ring. You want the balsa behind it to blend into it without altering the roundness of the part. Do your best not to sand any flats into the circumference of the nose ring.

Prepare for the tail section with four pieces of scrap balsa approximately 1/2-in. wide and 3 in. long. One should be 3/8 in., which is the thickness of the horizontal stabilizer; the second should be 1/4 in., which is the thickness of the vertical fin and the third and fourth should be 1/32 in. to emulate the thickness of the Top Flite MonoKote film that will be covering the stabilizer and fin when they are installed on the fuselage. Glue one of the thin strips to the 3/8-in. scrap and the other thin strip to the 1/4-in. scrap.

Cut a 1-in. length and a 3/4-in. length from the 3/8+1/32-in.-thick scrap, then use one or two tiny drops 46

I use a 1/4-in. round or rat-tail file to cut the scallop recesses at the tail, where the stringers are too close together to let me use the Perma-Grit or a rotary tool.

of gap-filling CA to tack-glue them over the stabilizer mounting area at the tail end of the fuselage. Get these scraps roughly centered between the fuselage sides, one about 1/2 in. from the forward end of the saddle and the other approximately 1 in. from the tail. These blocks are emulating the presence of the horizontal stabilizer.

Using no adhesive, dry-fit the 3-in.-long 1/4+1/32-in. scrap over the two scraps you just installed, sighting down the fuselage from the tail to ensure that the scrap is dead-centered between the fuselage sides and in line with the top fuselage stringer. This scrap simulates the presence of the vertical fin and must be carefully positioned as if it were the fin itself. When it is correctly aligned, apply a small drop of thin CA to each contact point between the “fin” scrap and the two “stabilizer” scraps.

Two tapered balsa blocks are included in the Super Sportster kit.

These are the tail blocks, and you will install them now. Use plenty of gapfilling CA or five-minute epoxy where the fronts of these blocks butt up against the rear-upright bulkhead, but use only a drop or two of gap-filling CA to tack-glue the tail blocks where they rest on the stabilizer and fin scraps.

25 I like to add scallops to the stringer work on most of the nonscale models I construct. The scallops don’t add much strength, but they do add a lot of flair to the appearance of the finished model. I make scallops by cutting scraps of 1/4 x 3/4-in. balsa into 1-in.-long strips, then tapering the sides of each piece to butt up against the canopy bulkhead and fit between the stringers. I do the same thing at the tail end of the stringers, using 1/4 x 3/8-in. balsa cut into 3/4in. lengths.

Shaping the rear end of the airplane comes next, and you can start by sanding the bottom sheeting flush with the fuselage sides. I like to keep this bottom angle sharp, but you can certainly sand a 1/16- to 1/8-in. radius along the entire bottom-toside joint if you prefer.

Lay the fuselage on its side and use the razor plane to trim one of the tail blocks to conform to the lines of the fuselage side and top, then flip the fuselage over and plane the opposite block to the same form.

If the scallop scraps of balsa between the stringers protrude enough, you can also use the razor plane to shave them down so that they will be easier to sand.

Switch from the razor plane to the bar sander and smooth those tail

blocks to perfectly blend into the fuselage sides and rear deck, then sand all the scallop scraps perfectly flush with the stringers, bulkheads and fuselage sides. Be careful here: you don’t want the scraps sanded flat.

Use finesse with the bar sander to make the scallop scraps conform to the curve of the canopy and stabilizer bulkheads.

Adding the curved scallops to the balsa scraps is fun to do and a whole lot easier than it might seem. You can eyeball it or use a length of masking tape to let you know how deeply to cut each scallop.

Here’s the tail section with blocks sanded and scallops cut and ready for that final sanding task.

tool, too, so switch to that if the gap between the stringers is too small for the larger tool.

If you haven’t got a set of PermaGrit tools, you can make your own round sanders by wrapping a piece of adhesive-backed sandpaper around a wooden dowel, a round brass tube, a paintbrush handle or anything else that will give you the approximate diameter you need.

The tail scallops are much closer together, so I cut the half-circles into the tail scraps with a 1/4-in. round rat-tail file. At this point, you can break the tail scraps out from under and between the tail blocks, but I prefer to leave them there until I’m actually ready to final-sand and cover the model. The tail blocks can easily be damaged or broken away from the

fuselage once the scraps have been removed.

So there you have it. The nose and deck blocks are installed, planed and sanded to shape; the tail blocks are installed, cut and shaped; the scallops have been added to the stringers on the turtle deck and the entire fuselage has been smooth-sanded down to #100 or #150 paper. I used the large, 3/4-in. round Perma-Grit tool to sand the tail end of the forward deck block to a pleasant curve where it meets the tops of the upper side strips at the front of the cockpit. That completed my Super Sportster 60’s fuselage frame-up.

I still have two sets of wings and four fuselages to construct, and I’m presently trying to figure out what I think you’d like to see next. It’s still up in the air, but right now I’m leaning toward that classic old-timer fuselage for the magnificent 108-in.

Building model airplanes is fun and rewarding, and there’s no feeling more rewarding than stepping back from an ongoing project, looking at what you’ve accomplished and mulling over the “you” that’s become a built-in part of the model. This is art, my friends, and your skills are surely developing.

The fuselage of the Great Planes Super Sportster 60 is essentially complete. All that remains is to drill and tap the blocks for the wing mounting bolts and add the small, underwing fairings at the front and rear of the wing.

Bill Sunick poses with his modified Stuka, refinished to replicate Hans Rudel’s aircraft.

By Rob Caso

I

agree with my longtime friend and flying buddy, Bill Sunick, that the Stuka is not a “cuddly, let’s make friends” kind of airplane. Like its fighter counterparts, the Bf-109 and Fw-190, one look at it tells you what it was built for and, for that matter, who built it. It has none of the graceful lines and careful pedigree of, say, a Spitfire. Nor does it have enough of a resume or good looks to one day become a show airplane or a racer like a P-51. A racing Stuka?

Perish the thought. No, the Stuka lived in the mud, doing the thankless job of an offensive guard on a rainy airfield in a grungy uniform. While the rest of the Luftwaffe was high above the muck bagging glory, Hans-Ulrich Rudel in his cannon-laden Stuka was bagging over 500 Russian armored

vehicles, oftentimes flying in weather so bad that, as he wrote in his autobiography, “even the birds were walking.” On at least one occasion in such conditions, Rudel actually landed on a road and taxied back to his lines.

Can you imagine the looks on the faces of troops who saw that thing rolling in? Go read his book, Stuka Pilot, and find out.

With all that history and color, Bill and I both agreed that if Bill was going to do a Stuka, there really was only one to do—Rudel’s “G” model “Kanonenvogel” in winter camouflage, as if you had to ask. The “D” and “G” both were upgraded with a 1400-hp Jumo inverted V-12 engine, thus alleviating the “Sorry, I have the mumps” look of the earlier versions. We feel that the later

variants are the best looking of all the Stukas, but for some reason, they are not often modeled. Although the Nitro Planes model’s outlines are arguably the best of any ARF Stuka we researched, Bill improved the model by eliminating the foam’s surface texture and extensively modifying the kit to fix known weak points and scale deviations. My role was limited to painting, weathering, technical assistance and sarcastic comments.

that little effort is made in the factory to remove the release agent prescribed by the molding process.

As a result, the factory paint is hanging on by its fingernails and will easily come off with any masks that may be applied later. Bill completely stripped the model, degreased the bare foam with denatured alcohol and then firmed up its surface with a mixture of Durham’s water putty and vinyl spackle. This was sanded and then primed with Duplicolor auto body primer, which does not attack the foam. With all the Stuka’s lumps, bumps and pieces, this was a big job, further complicated by the need to leave the scale panel lines intact.

The refinish included eliminating the servo lead runs carved into the underside of the wing, which were

simply taped over by the factory.

That might work for a Sunday fun flier, but it wasn’t good enough for us. Bill installed servo leads running from the fuselage section of the wing to the ailerons and flaps and then buried them with glass and filler. This still left the option of replacing the servos. He eliminated the flap servos in the wing root radiators, leaving the outer flap servos in situ to do all the work. Small steel rods were installed between the inboard and outboard flaps to make all four work as one; flight testing showed that this setup worked fine. Bill also moved the rudder and elevator pushrod exits further aft and employed a steel rod joiner for the elevator, thus eliminating a pushrod altogether. Bill modified the kit’s tailwheel, a known

failure point, by replacing its vertical strut with a steel piece.

After the bare foam was refinished and the infrastructure modifications completed, Bill again primed the model and then applied the standard Russian front scheme of RLM 70/71/65, using Model Master enamel. He painted some of the markings, but with the NEAT fair deadline looming, I bailed him out on the rest. Although not quite ready for the prom, the model at this point was deemed flyable, although Bill made a last minute change, up-gunning to an ESC with a higher current rating—another known failure point in the stock kit. After squabbling over where the center of gravity (CG)

should be (22–25% of the root cord including the flaps), I got the dubious honor of making the test flight. Why he asked me to do this I will never know, although my record with him is surprisingly good.

Since all dive-bombers have a ton of wing area, I was expecting “advanced trainer” flight characteristics, and the Stuka didn’t disappoint. After a couple of trim adjustments owing to slightly out-oftrue foam control surfaces, the Stuka flew as if on rails, but it was also responsive and maneuverable. A slow and deliberate power application for takeoff was best, and the model got off the ground realistically at only about 60 percent power. The

Nitro Planes’ Ju-87G Stuka above flight equipment was plenty for this model, although some people inexplicably fly it on a 4S LiPo battery pack, which simply adds unnecessary weight and provides non-scale flight characteristics. If the takeoff was easy, the required landing was even less exciting. Drop the flaps, set the model up on final and then go have a sandwich. Some flyers noted that the model changes pitch at full flap, but I experienced none of this—the Stuka is steady as a rock coming in and just about as slow.

Reinvigorated by the successful flight testing, Bill and I ran home to finish the model. The Luftwaffe’s winter camouflage consisted of a sprayed, brushed or broom(!)applied water-based whitewash over the entire upper surfaces, but avoiding the markings and any other significant nomenclature. Clearly, this job was usually done in haste, and the whitewash easily came off with weather or from use. Using some photo references, we applied squiggles of Silly Putty for a mask over the airframe and airbrushed on a translucent, uneven coat of grayish white, which was later toned with gray and brown. Removing the putty revealed lines of the base camouflage, over which I airbrushed some white to blend them. Just prior to airbrushing the white, we applied chunks of moistened table salt in likely wear areas to impart a chipped effect owing to crew activity, propeller debris and general wear.

After painting the exhaust tips with a muddy brown mix, I airbrushed the exhaust stains using progressively darker shades of tan, brown and burnt umber, ultimately going to black near the exhausts. The key is to make successive passes and build up the effect slowly and with numerous colors—exhaust stains are not all black. The panel lines were highlighted in a similar fashion, this time with a double action airbrush, but the mix included a lot of clear and was much more translucent.

Final assembly included the installation of a pair of scratch-built MG81Z machine guns, an instrument panel, the crew and even an antenna

We used Silly Putty strung over the wing’s surfaces to mask the base camouflage for the whitewash.

wire from elastic thread. Bill superdetailed the 37-mm cannon by drilling in blast deflector holes and adding various scoops and tubes. A sound system for the cannon provided even more intimidation.

A lot of work for a foamie? Yes, but Bill’s Stuka is now an accurate and unique representation that—with all the kinks worked out prior to putting it in the air—will be a reliable and pleasant everyday flier. Now we just have to wait for some bad weather …

Two-Stroke Glow Power to Write Home About

he O.S. 120AX offers a 20 percent increase in displacement and power compared with .91-size engines, while adding almost no additional weight.

Also, it fits into the .91’s mounting space. Sounds good, right? Now O.S. has taken things a step further by releasing the 120AX Special—an improved performance version of the 120AX. According to O.S., the primary impetus for this higher-performance version was to provide an improved power plant for AT-6 Texan Pylon Racing, which is very popular in Australia. We don’t care what the reason was for the new engine, but we definitely like reaping the benefits of an additional 8–10% power output with the usual level of O.S. reliability and ease of tuning.

O.S. made three fairly simple changes that work together to deliver the performance gains.

Importantly, they did so without

sacrificing reliability or durability in the process.

Why to Buy

The O.S. 120AX Special produces excellent power in a compact package yet fits in the same space as a .91-size engine. It is offered at a reasonable price. This new engine delivers outstanding reliability and ease of tuning, O.S. hallmarks. It is compatible with a broad range of propeller sizes, making it suitable for The 120AX Special is a compact and attractive engine, combining the usual outstanding O.S. casting quality and appealing, functional design of the cooling fin shapes. The only externally visible difference from the standard 120AX is the machined aluminum velocity stack attached to the carburetor.

larger-scale, aerobatic/3D or warbird aircraft.

Break-In and Performance Testing

I used Wildcat brand 15% Premium two-stroke fuel for break-in and testing. There are plenty of other fuels on the market that will perform just as well, but just make sure that the fuel you select complies with the requirements listed in the user manual.

O.S. specifies 15 x 10–12 or 16 x 8–10 propeller sizes. As part of this review, we tested these sizes, plus a 17 x 6, to fully explore the 120AX Special’s capabilities. We also did some comparative testing of different muffler adapters offered by O.S. After mounting the engine to the test stand, installing an APC 15 x 10 propeller, fueling the tank and connecting the hoses and doublechecking everything, I primed the engine by choking it and flipping the

O.S. 120AX Special propeller a few revolutions by hand.

The engine started promptly. I used my Sullivan electric starter to turn it over. Later I would flip start the engine many times and found it very easy to start by hand.

The O.S. break-in process requires running the engine at full-throttle with a widely varying, high-speed needle setting. Basically you run the engine very rich for several seconds, then lean it until the rpm comes up and it’s running clean at near-peak revolutions. You hold it there for a few seconds, then immediately richen the high needle until the engine slows considerably and starts blowing a lot of smoke and fuel mist from the exhaust. You’ll repeat this process for a couple tanks of fuel, with steadily increasing durations of near-peak rpm periods. I found that it tuned well and idled/transitioned really well even

before completing the initial break-in running.

Once the break-in was complete, I tuned the low and high needles in a back-and-forth manner until it delivered slow and steady idle speed, with clean acceleration when the throttle was opened rapidly. I set the high needle about 100 rpm on the rich side of peak (a few clicks more open on the high needle than the setting that produces highest rpm). The instructions included a clear, step-by-step approach to tuning the carburetor. After break-in and tuning, the engine could easily hold 1500–1600 rpm idle without stumbling upon quick throttle opening, and it also held steady rpm at full throttle.

I used a digital sound pressure level meter on a tripod to collect sound pressure level data. The meter was set at the same height as the crankshaft centerline, with the meter at a 45-degree rearward angle from the propeller hub, at a distance of 10 ft. The meter was set on the A-weighting scale, which simulates the frequency sensitivity of the human ear. The E5020 Power Box muffler (not

propeller.

After testing the eight propellers included in this review, I performed a quick test of two optional muffler adapters—first the straight exhaust extension adapter, then the 90-degree adapter. It is interesting to note that the performance improved slightly when using the adapters. This is most likely the result of increased length and volume of the exhaust tract upstream of the muffler.

After break-in, I moved on to my standard step-throttle test with each of the eight propellers. The test that I run has the engine running for five seconds at stable idle, then five seconds at 20 percent throttle, then five seconds at 40 percent throttle and so on, with the final five seconds at wide-open throttle. All the while,

the data system is capturing rpm, thrust and ambient temperature. The engine ran well with each propeller and required only very slight adjustment to the high-speed needle when switching amongst the various size and pitches of propellers—this due to the large variation in load.

There are several graphs included in this test report. They demonstrate how the engine performs with each propeller. Of particular interest is the “Thrust vs. Throttle Position” graph, which clearly depicts what static thrust the engine/propeller combination produces over The optional angled exhaust adapter allows the muffler to be mounted in a way to keep the exhaust system inside the cowling for certain types of aircraft.

The O.S. 120AX Special is an excellent choice for a broad range of .91- to 1.20-size aircraft, where a powerful, compact, reliable and easy-to-tune engine is desired. The engine ran perfectly throughout all testing, and it idled extremely well and accelerated quickly even after an extended idle. Additionally, vibration levels are low for an engine of this size. As demonstrated in this review, the engine is happy to perform with a very broad range of propeller sizes.

This graph shows how thrust output varies with throttle position. To compare maximum thrust, just look at the right side of the graph at 100% throttle. Note that the thrust response is rapid from idle up to 20%, and then fairly linear from 20% to 80%, and not much more is gained going from 80% up to 100%.

Quarter-scale Six Months in the Making For this Beauty

P

edro Sanchez has a passion for warbirds! His hangar is full of them.

His latest project has been a 1/4-scale Chance Vought F4U Corsair.

The build started when Pedro was given an expensive handmade aluminum tail wheel by a friend.

It was a perfect fit for a 1/4-scale Corsair. Then all he needed was an airplane to put it in. The tail wheel was the motivation Pedro needed to build the Corsair.

He starting by using a set of Ziroli plans that he had blown up to 1/4-scale size. Pedro’s Corsair is built mostly of balsa and aircraft plywood.

The wings, tail and fuselage were sheeted and glassed. Then rivets, spot welds and panel lines were added to detail it. The outer wing panels are fabric covered aft of the main spar, as are the ailerons, rudder and elevators. The unusual paint scheme and graphics bear the number of an aircraft that belonged to the Georgia squadron and was flown in the Pacific.

Pedro found the details of the aircraft online.

The 110-in. wingspan, 70-lb Corsair is powered with a mighty four-cylinder DLE 222 engine. It swings a Solo three-blade, 32-in.

project rolling was found not to fit during the build! Pedro discovered that its location was too far aft as shown on the plans. In the correct location it fit perfectly.

This project required a lot of work, but Pedro took only six months to complete it.

Here we see the functional trim tabs on the elevator—just for looks on the ailerons. The control surfaces are fabric covered with rib stitching and weathered for realism.

The $500 tail wheel that prompted Pedro to build this beautiful warbird. Manufactured by Tim Hughes, it has each part hand machined from aluminum and is fastened together with small screws—truly labor intensive but a work of art. I’m not kidding, he does get $500 for them.

18MZ Radio System High-end 2.4-GHz Performance with Telemetry

This feature-rich transmitter system delivers lots of programming power and an ergonomic design that gives you a competitive edge.

F

utaba’s new flagship radio system, the 18MZ, adds telemetry to the 2.4-GHz Futaba transmitter lineup. For those who are not familiar with it, telemetry is when an airplane’s transceiver communicates bi-directionally with the transmitter to provide real-time data from the airplane, glider or helicopter. The flight data can be information such as engine rpm, airspeed, altitude, current, temperature, rate of climb, battery voltage, GPS location or fuel level.

The pilot or co-pilot can either read the information on a display or get the data audibly. Also, various alerts and alarms can be set to announce when a preset threshold is reached or crossed. For example, you can program the system so that the transmitter will vibrate whenever the battery voltage drops below a certain value.

Telemetry is extremely useful for pilots and co-pilots. Not surprisingly, once you start to use it you will wonder how you managed to fly RC aircraft without it.

While telemetry is a huge part of the new Futaba 18MZ transmitter, it is but one part of this new featurerich, extremely programmable system.

In fact, one could argue that the Futaba 18MZ is one of the most capable 2.4-GHz transmitter systems now being sold in the USA. Its user interface, ergonomics, control sticks, levers and switching systems are extremely well engineered. While not the least expensive transmitter in the RC marketplace, this 18-channel system provides the programming power that the professional pilots demand and use to win contests.

Let us explain why this new

68

RC SPORT FLYER — november 2012

system is worth every penny you’ll spend to buy it.

Package Contents

The 18MZ comes in a strong, attractive brushed aluminum case. All of the standard RC components are included: transmitter, wall charger, neck strap, switch harness and receiver. The transmitter is equipped with a 7.4-V 3500-mAh LiPo battery as standard with the system, which will provide six hours of run time.

The battery is easy to remove or replace too—just open the side cover on the side of the radio, lift the cover and slide it out. Futaba includes an extremely detailed and helpful 164-page printed manual, which is available as a PDF downloadable file. Even though the manual will explain how to use this new high-end transmitter system, the logic of the programming is so well engineered that programming the radio is nearly

intuitive. The manual comes with a removable clasp and is three-hole punched so it can be put into a binder if you’d like.

18MZ Transmitter

This is Futaba’s first 18-channel RC transmitter. It offers 16 proportional control channels and two digital ones. Most pilots will never need that many channels, but if you fly large-scale or model aircraft with complex control systems, the

Futaba 18MZ is a perfect choice.

At 41 oz (1.16 kg), this transmitter is definitely heavier than some of the other transmitters in its class. The 18MZ’s case has a very utilitarian design to it, as does its touch-screen display. This Tx feels very solid in your hands and is surprisingly comfortable to use. The trim levers are well positioned, as are the three-position switches and four ratcheted sliders (two on the front and two on the sides). The on/off buttons are well

At 41 oz the Futaba 18MZ is not a lightweight transmitter, but its extra mass and excellent hand-hold design mean the transmitter will remain steady in your hands.

placed just above the neck strap clasp. There are three rotary volume controls just below the antenna base.

The control sticks are ultra smooth, and each can be tensioned to fit the pilot’s preference. At the bottom of the touch screen are four rectangular buttons for System Menu, Linkage Menu, Model Menu and Return.

Just below them is a rotary key for toggling between display functions.

Finally, the durable handle at the rear top of the transmitter’s case makes for easy carrying.

On the back of the radio is the trainer port. Below it you will find a small door that provides access to the headphone jack, charging port and direct connect for the S. BUS. On the transmitter side is a door that slides to the back of the radio, allowing access to the LiPo battery, two USB (universal serial bus) ports and the SD (secure digital) card, which in the case of this radio is 16 GB. No matter how you look at this transmitter system, it is engineered, designed and built for the serious RC pilot/competitor with solid, logical functionality. Its programming, ease of use and ergonomics will inspire an RC pilot’s confidence, as will the extremely solid, dependable Rf

As you can see, the sliders and switches are redundant from side to side. This gives the transmitter a balanced feel in your hands so you won’t be searching for a control.

communication between transmitter and receiver due to FASST technology.

The 18MZ’s massive 6-in. (15cm) wide touch screen is bright and easy to read. The screen’s resolution is 640 x 240 pixels and provides RGB color. You will have no problems seeing this screen, even in bright sunlight—although polarized sunglasses can decrease its visibility.

Even when compared with other high-end transmitter system, the variety of switch, knobs and sliders is outstanding and well placed. Note too that the unit not only provides the typical stick length and tension adjustments but control stick angle adjustment as well, which adds to the pilot’s hand comfort. You’ll discover that the entire gimbal assemblies can be adjusted out towards the pilot’s hands. Even more intriguing, the shoulder switches mount on removable assemblies. Consequently, it is easy to replace a threeposition switch with a momentary switch. Also, in case you drop your transmitter and break one of its switches, you no longer have to send in your transmitter to the service center for repair. You just order the switch you need and then plug it into its respective position.

The 0.3 megapixel camera is built into the back of the transmitter so you can easily take a photo of your airplanes, which can then be associated with their programming.

70

RC SPORT FLYER — november 2012

The transmitter’s controls are balanced from side to side. You can adjust the control sticks’ tensions by way of removable covers on the back of the transmitter and holes in the case.

The 18MZ offers you many connectivity options too. It has built-in USB ports that let you plug in a standard computer mouse and keyboard for ease of programming in your shop or home. Using the USB port, USB memory stick or SD memory card you can also upload model data, pictures and sounds to the transmitter. You can even take a picture of your model using the built-in 0.3-megapixel digital camera (on the back of the Tx’s case), which you can then associate with the

model’s data. The 18MZ lets you play stored music through a speaker or headset jack so you can fly your models to your favorite tunes. A built-in microphone lets you record short voice clips as well, which you can then associate with any of the transmitter’s switches. The audio file will play when the switch you’ve assigned to it is flipped. And, since assigned sound files are specific to a model, you will hear what each switch does when you toggle it. You can even chain together multiple audio

FASSTest

In addition to the laundry list of high-end features mentioned above, another reason to buy this transmitter system is its new telemetry support. The telemetry features were made possible through two complementary technologies: FASSTest and S.BUS2.

FASSTest (Futaba Advanced Spread Spectrum Technology Extended System Telemetry) builds on the proven Futaba FASST technology. This is a true frequency-hopping, spread spectrum signal encoding scheme that has proven to be very robust against radio interference.

S.BUS2

The wall charger for the LiPo battery is functional for voltages from 100–240 V AC, with an output voltage of 12 V DC. It is included with the radio system and will work internationally.

You’ll get a switch harness and an S.BUS connector as well. Once you use this radio you’ll most likely be ordering more as you convert all your airplanes to 18MZ control.

architecture that dramatically simplifies installations. For example, with the 18MZ system, up to 18 servos can be daisy-chained together in a serial bus fashion, with only a single wire connecting them to the receiver.

There is an unexpected bonus to these technologies too. A traditional receiver is limited by the number of physical servo connectors on it. An eight-channel receiver, for example, needs to have eight servo connectors on it. When your model is outfitted with the Futaba serial bus system, that is no longer the case.

With S.BUS technology, any S.BUS receiver can handle any number of channels, up to the limit of the transmitter.

RC-SF.COM

71

Futaba® 18MZ Radio System Part 1 While S.BUS was a huge leap forward in RC receiver/ servo communications, it was not bidirectional. With the introduction of telemetry systems, Futaba opted for a new communication protocol defined as S.BUS2. S.BUS2 provides bidirectional communications between the receiver, the hubs and the servos as a way to pass telemetry data. This advance in bus technology makes it easier than ever to installed telemetry systems in any part of your aircraft because a telemetry device can simply be plugged into a bus slot position. Note that the new S.BUS2 serial bus system replaces, and is incompatible with, the older S.BUS technology.

R7008SB Receiver

receiver is a marvel of modern RC technology. Weighing only 11 g (0.39 oz), this receiver sports a full array of traditional servo connections (eight channels), an S.BUS port and an S.BUS2 port. In other words, if Futaba makes the servo or gyro, it can be connected to this receiver.

If that weren’t enough, this receiver has another option. It can be configured so that it responds to transmitter channels 9–16 instead of channels 1-8. This feature allows you to configure your airplane with dual receivers so that the two onboard receivers share control of the airplane’s functions.

hen flying a remote control (RC) aircraft, the pilot must be able to control it with ease for optimal performance. Options like retractable landing gear and flaps require a transmitter that can handle those function as well as the basic controls.

Add programmable mixes along with 3D control functions, and the transmitter must have added control power. In today’s RC world pilots are starting to demand flight data to understand the aircraft’s realworld performance. There is a very powerful and affordable transmitter that can give you this power now and into the future. Enter the most sophisticated transmitter Hitec has produced to date, the simple-to-use Aurora 9.

The Aurora 9 is an Adaptive Frequency Hopping Spread Spectrum (AFHSS) 2.4-GHz, PPM/PCMcompatible transmitter. It comes in an ergonomically designed, lightweight case that features a 5.1in. backlit touch screen. It includes nine assignable control channels.

The control sticks have grip tips that fit one’s fingers or thumbs comfortably because of their flared tops and adjustable lengths. They deliver excellent control response due to their ball-bearing gimbals and adjustable tension controls.

The Aurora nine-channel transmitter has memory storage for 30 models. It can be programmed for three different model types: ACRO for powered airplanes, GLID for gliders or HELI for helicopters. All the model types have programming functionality in depth with customizable menus. Once you’ve programmed an airplane setup into 74

menu, pilots no longer have the hassle of removing and replacing the adaptor to swap channels.

Battery options include the factory-installed six-cell, 2000-mAh NiMH, a six-cell NiCd or a two-cell LiPo battery pack. With the LiPo option, however, the battery must be removed from the transmitter for charging. The charger that is supplied with the transmitter is only meant for NiCd and NiMH packs. The stock charger is compatible with either 100 or 220 V DC. The charging port is found on the back of the transmitter.

Hitec Aurora 9 Part 1 A series of four toggle switches and two trimmers are at your fingertips. They can be used as channel controls or adjustment controls for your aircraft.

On the right top side are four toggles and one trimmer that function the same as those on the left to allow for the pilot’s control preferences.

When programming an aircraft’s parameters into the Aurora 9, certain channels will be automatically assigned to specific switches, but can be re-assigned to other controls later.

The charger is designed to charge a 4.8-V receiver pack as well.

Touch screen navigation is easy! You simply touch the word or icon on the display to access menus. Then you’ll adjust values in the same fashion by touching the screen appropriately. The touch screen eliminates the need for extra buttons, which leaves the front of the transmitter clean. Accessing the system menu and sub-menus is done by touching the wrench icon on the screen. It’s extremely intuitive navigation.

The home screen menu provides easy-to-read model number, name and type information on top of live data that may come from your model’s onboard telemetry. All screens are organized well and provide excellent pilot information and feedback.

The transmitter comes with the now-standard digital trims and programmable sub-trims. They RC-SF.COM

provide you micro-increment adjustments as small as 0.025 degrees or as large as five degrees per step.

The trims can also be mixed to control surfaces, such as syncing aileron and rudder trim.

Programming an aircraft’s control setting is a piece of cake with the Aurora 9’s simple setup procedure.

You’ll begin by using the system menu, which lets you create a new entry in the model selection screen.

Next you can name the new entry using up to 20 characters. From there, the corresponding model, wing, tail and engine types for the aircraft are selectable. If the aircraft has retracts, an air brake or a fuel control, you are given the option to enter that information. After that, you can preview what channels on the transmitter are assigned to specific functions on the aircraft and decide if the configuration is what you want to save. Once done, a few taps on the

The arrangement of the left top side control switches and toggles allows for easy simultaneous operation without having to disengage the control stick.

The addition of a slider control on the left side of the Aurora 9 allows for smooth input to variable aircraft controls such as flaps, or for mixing controls in flight.

back (exit) icon and the transmitter is ready for use.

Also you can customize servo reversals, sub-trim, endpoint adjustment, dual rates and exponentials for your specific model.

When programming dual rates and exponentials, a graph is shown to give the pilot a visual of how smooth or coarse the adjustments are for a specified control.

Special advanced settings give

helicopter pilots the option to set needle control, governor, rudder/ throttle mix, servo speed, swash/ throttle mix and gyro sensitivity to further the control of the aircraft.

Other specialty settings allow glider pilots to assign air brakes or flaps to a toggle switch, as well as launch mixes for the ailerons, flaps and elevators to other switches. These adjustments are specific to each model type you will program, so for

the multi-talented helicopter and aerobatic pilot, switching settings from one aircraft type to another is done when switching between models.

Veteran RC pilots will appreciate the flight condition options with seven customizable modes and the default “Normal” mode. What makes this feature unique to the Aurora 9 is that a switch can be programmed to toggle between different flight conditions, such as shifting from the normal mode to a customized 3D mode.

Aircraft control assignments aren’t all that can be programmed into the transmitter’s memory either.

The transmitter’s power settings are programmable too, so you can customize how long the backlight remains on and enable or disable auto power off to save on battery life. When running the Aurora 9 on a LiPo pack, you can reprogram the low-voltage alarm value. This will save the LiPo battery from being drawn too low, which could ruin it. Also, should you be an international buyer of the transmitter, you can switch the transmitter control modes between three continental locations.

Value

Priced at only $799.99, the DX18 is a great value. This is especially so when you consider that the transmitter incorporates Airware™ and X-Plus™ technologies, plus telemetry. Airware is Spektrum’s programming architecture, which makes navigation of the menus and programming easy by way of the SimpleScroll™ interface. X-Plus lets you add eight extra channels of control to your receiver system when you are using the DX18 mated with the AR9020 receiver. In that case you just plug a module into the AR9020 and bind it to the DX18’s guide-coded signal. It is straight up, as they say.

The DX18 is the perfect pick for pilots who are looking to upgrade their system or who need extra control channels for an airplane, sailplane or helicopter. Spektrum now offers the DX18QQ, a special-

XG11

T

op-level pilots fly the biggest, fastest and most complex and competitive model aircraft available today. They demand an RC transmitter that has the most programming power available— one with high-end control mixing, three control rates, precise control sticks, low latency and a system that allows for fine-tuning adjustments to control surfaces and functions.

Control over nearly every variable of their complex and intricate aircraft is essential. The Japanese Remote Control Company (JR) has long recognized the demands of these pilots.

JR has been in business many, many years. It has an outstanding reputation in the RC business, having produced high-end, high-quality radio equipment for the world’s best RC pilots. JR manufactures transmitters, servos, receivers, programmable robots and other electronics. It was also a pioneer in the area of 2.4-GHz radio systems. Now JR is introducing its new flagship radio system, the XG11.

What You Get

The ergonomic design of the XG11 is best seen in the easy-to-reach placement of the throttle stick, trim tabs and corner switches.

84

RC SPORT FLYER — november 2012

The new XG11 comes in a sturdy box that has two styrofoam shells to safely encase the transmitter and the accessory equipment.

My XG11 radio for this review arrived in perfect condition.

Inside the box was a JR Propo RG1131B 11-channel DMSS receiver, which is purposely built to work with the XG11.

The receiver features two coaxial antennas and a remote antenna that is designed to take advantage of the XG11’s new spread spectrum technology and telemetry.

Operating each switch with the index finger and The transmitter moving the sticks with the thumbs are accomplished comes equipped with by feel—you need not look down!

JR XG11 Part I a 2S 6.4-V 1400-mAh LiFe battery installed. A wall charger that can adapt to voltages from 100–240 V at 50–60 cycles, and that delivers 1.3-amp, 9 V DC, is included. The LiFe battery is lightweight and is charged through a regulated control circuit built into the transmitter.

A 124-page user’s manual is provided and is also available as a PDF download from jrradios.com. It provides extensive details on how to program the transmitter for airplanes, helicopters and gliders. It is an easyto-follow instruction set, with stepby-step procedures for programming the XG11 for all types of aircraft.

The manual includes illustrations alongside the text to guide you through specific procedures.

A packet of tools and hardware for adjusting the stick plates and a bind plug are included in the XG11’s package as well.

The controls are built around the pilot’s hands. The switches and sliders are comfortable to reach with the index fingers.

Showcasing the special attention paid by JR, the placement of the rear sliders and snap switches complements the transmitter’s handholds.

What DMSS Is

The JR XG11 11-channel transmitter incorporates a 2.4-GHz system called the Dual Modulation Spectrum System (DMSS). DMSS uses broadband frequency hopping over a spread spectrum rather than the conventional hopping over a narrow band. This ensures that when RF noise or competing noise is present, the control signal will reach the receiver intact. Unlike most other 2.4-GHz systems, DMSS uses a wide band RF transmission that runs across a true spread spectrum, so its signal is durable and resists RF noise. The radio’s DMSS-equipped receivers also make use of dual coaxial antennas and a remote receiver to allow for operation in any RF environment.

Two-way communication between the transmitter and receiver allows for the receiver to transmit aircraft flight data back to the transmitter via a built-in telemetry system.

The telemetry data is displayed in real time on the transmitter’s LCD screen—very cool!

Note that the XG11‘s new E-Z Bind system eliminates the need for a bind plug in specific park flyer receivers. You only need to turn on the transmitter, and after three seconds the receiver will recognize

Switches, stick, trim tabs and menu buttons can all be toggled effortlessly.

the RF signal from the transmitter and automatically bind to its 2.4-GHz signal.

The Transmitter

You can see that the XG11 has a clean, ergonomic design that is enhanced by a metallic face with very little clutter in design. The large backlit screen is easy to read and displays all of the programming

information in an easy-to-understand logic system. The XG11’s case is plated in a great-looking titanium finish that is extremely durable.

At 2 lb (32 oz) with the LiFe battery installed, the transmitter is lightweight and easy to hold. Your hands will conform to the case and its grip pads, which provide a natural and comfortable hold. The on/ off switch is well positioned in the RC-SF.COM

center of the transmitter, just above the LCD screen. The control sticks are well positioned too. They are adjustable and have serrated machine tops that help you grip them easily and securely—no slipping off the top with these. The sticks’ gimbal are smooth and accurate, with adjustable tensions—but you must remove the case back to adjust them. The trimmers are located in the typical fashion below and to the sides of the sticks. They are easy to reach and comfortable to use. Placed at the top left of the transmitter’s case are two three-position switches and two twoposition switches. Two long toggles in the cluster as well help you recognize them by feel. There is a slider control, which uses indent positioning, on the top back of the transmitter. You can easily access it with your index finger.

There is also a trimmer position to the right on the long toggle on the front of the transmitter. A mirror image of the switches, trimmer and controls is positioned at the top right of the transmitter, with the exception of the long toggle snap switch on the very top back position. There is another slider in the mirrored position from that of the one on the left. All the switches on either side of the transmitter are positioned so that the pilot will recognize their function by feel only.

On both sides of the transmitter’s top are indents where switch identification stickers can be placed.

Stickers can reference default control assignments for their corresponding switches. They are useful if you’re going to be flying without any 86

customized control assignments, but for most pilots the stickers won’t help much because different models may have switch assignments.

On the transmitter’s back, the module appears to be removable, but it is not. A direct servo connection (DSC) port is located right below the module, and the battery compartment is located at the very bottom of the backside. To remove it you must slide the cover down by grasping and pulling. The 6.4-V 1400-mAh battery fits snuggly in a foam receptacle. There is an SD card reader slot on the circuit board just to the right of the battery lead’s connector. It is easy to add and remove an SD card to the slot, but you’ll want to remove the battery first.

The case has a built-in handle on its back. When you pick up the transmitter by the handle, the transmitter rolls away from the antenna, which helps protect it from accidental damage. The antenna folds to the side as is now typical with most 2.4-GHz radio systems, keeping it out of the way of damage as well.

How It Works

Navigating the programming menus is easy. It follows in the logic of other JR radio systems in using ladder logic. For example, to enter the System Menu you would hold down the E function keys to the left

A detailed manual comes with the transmitter, providing easy-to-follow instructions and illustrations for operation.

of the LCD screen and then turn on the radio. Or navigate to System Menu from second page of the Function List. Once in the System Menu there are 20 programming options available. They include: Model Select, Copy/Erase, Type Select, Model Name, F-Mode Name and so forth. You can navigate through these programming menus with the well-placed rolling selector, which operates by rolling and clicking.

To enter the Function List you simply press the LST button, which is the second button down on the four to the left of the LCD. It is marked with a large L. The Function List includes 25 options for programming.

They include such functions as D/R & Exp, Travel Adj, Limit Adj, Sub Trim, Servo Speed, Mixes and Pitch Curve.

Again, you will navigate through these programming menus with the rolling selector. It is quite easy to program this transmitter system once you understand that there is a System Menu for setting up the aircraft and a Function List as well.

DUPLEX DC-16 A Fresh, Functional Face in an RC Transmitter & Receiver

J

ETI model Company is known in the RC world for their speed controllers and motors. JETI has been in business since 1993 when Mr. Jelen and Mr. Tinka formed a partnership to produce electronic speed controllers.

The company has grown significantly since then and now offers a range of electronic components that use surface mount technology. Their latest entry into the RC market is duplex transmitters and receivers, including the new and exciting DC-16.

The DC-16 is a paradigm shift in transmitter design and technology. It was built from the ground up by a team of professional pilots and world champions.

The project plan was to create a transmitter/ receiver system that would provide an optimized user interface and programming

The DC-16 design goes back to the basics, giving you function and features before form. The control sticks, switches, sliders and programming buttons are very well positioned.

options yet be extremely durable and easy to program.

In the Case

What you get when you open the sturdy aluminum case is a 16-channel transmitter housed in an inner foam case. There is an R9 nine-channel receiver and a 100- to 240-V AC wall charger. Also, a 6-ft-long, five-pin mini-B USB cable is included, which provides the transmitter to computer connection when needed.

On the top of the radio you have the antennas buried inside the handle. To the right of the handle is the mini-USB port, while to the left is the charging female receptacle.

RC SPORT FLYER — november 2012

Jeti USA DUPLEX DC-16 Part I

In the upper right corner of the case’s face are two three-position and two two-position switches. There is also a rotary knob with a slider on the right side of the case.

Our review radio came with a very well-made, carbon simulated transmitter tray. We also ordered some of the telemetry gear including: a four-channel expander, USBa, GPS, variometer, voltage sensor, speed sensor, voltage and current sensor and battery voltage sensor.

Transmitter Design

The DC-16 transmitter is built around an extremely rugged and durable aluminum case. It includes two control sticks with adjustable lengths as well as tensions. They are metal quad-ball-raced sticks that use Hall sensors to provide maximum control sensitivity and friction-free

The upper left face of the transmitter is a mirror image of the right in both position and function. Notice the numbering, which represents the switches and channels.

movement. The control feel is silky smooth—almost unusually so.

At the center top of the front panel is a 3.8-in. backlit LCD display.

It provides a clear, legible screen that you can see in any lighting condition.

Just below the LCD screen are five function buttons (F1–F5) that you will use to start timers, clear settings, navigate around the boot-up screen and move left and right in the on-screen menus. To the immediate left and right of the function buttons are one each three-position toggle switches. The power button is positioned just below the navigation buttons. In the upper right corner of the transmitter’s face are four

In the lower right corner of the transmitter’s face is the menu, rotary selector with selection button and the esc key. In combination these are super easy to use when programming the Tx.

toggle switches—two are threeposition and two are two-position.

Adjoining these switches, but to their lower left, is a rotary knob you can program for a specific function. The switches and knobs are mirrored on the upper left side of the transmitter.

Below and just slightly to the left of the right control stick (channels 1 and 2) are the digital trims for this stick. Again, it is mirrored for the left stick (channels 3 and 4). On both the upper right and left sides of the aluminum case are slide levers, which are smooth and friction free. In the lower right position of the case are the menu and escape buttons with the 3D wheel positioned between

them. In the bottom left corner of the transmitter’s face is the speaker with a headphone jack positioned to its lower right. On the top of the transmitter is the antenna, which also serves as a carrying handle.

A mini-USB port is situated to the right of the antenna, and a charge port is to the antenna’s left. All the switches are labeled on the case from sa through sj. Also, the control numbers are marked, as are the trims, menu and escape buttons and phones.

Consequently, you can look at the radio and know what toggle, knob or lever belongs to a specific control function. It is extremely well laid out.

When we put the transmitter on the scales it weighed in at 51 oz. So, we recommend you buy the transmitter tray, which will help you be more steady at the control sticks—that is once you get used to the idea of using a tray.

This photo give you an oblique look at the right side of the transmitter.

Notice how the slider is machinefitted into the right side of the case. It is ultra smooth to operate too.

Basics

Booting up the DC-16 is easy.

You simply press the power button for about one second and then confirm that you want to turn it on by pressing the Yes function button.

Once the radio has started, the LCD screen displays the battery voltage as a percentage, the name of the model and the page number you are on in the model selection. There is an Opt. (option) function, a left and right arrow for the pages, a Start and a Clr (clear) command. To enter the menu

you simply press the menu button in the lower right of the transmitter’s face. You can then move up and down the Main Menu with the 3D wheel.

Your options there are: Model, Fine Tuning, Advanced Properties, Timers/ Sensors and System. You can also select the User at this screen as well as the throttle lock and the servo

A Paradigm Shift

The new DC-16 transmitter is somewhat of a paradigm shift in terms of programming, functions and features. Although it gives you the ultimate in control response and sensitivity for your model, what really separates this radio from the others is its look, feel and easy of programming. We found it so intuitive

This is the Main Menu. As you can see there are five options to choose. At the bottom of the screen you can select the User or Throttle Lock and see the status of the servos’ positions.

We also learned that Gernot Bruckmann is now flying the Jeti DC16 system. As you may have read he walked away from the Clover Creek Invitational event with $20,000.

Gernot is also a three-time Tucson Shootout Freestyle champion as well as the German Acro Cup winner.

So, it is safe to say his DC-16 gets a workout and then some.

Obviously this transmitter/ receiver system is not for everyone.

However, if you’re looking for a radio system that offers options, this is a radio worth investigating. Priced at $1295, it just might be a huge bargain for a 16-channel, programmable radio system.

At the System Menu you have eight options. To choose one, you simply rotate the selection wheel until you’ve highlighted the function you want. Then you push the selection button on top of the wheel.

Fine Tuning also gives you eight options.

Again, it is easy to make a selection and then program that selection’s parameters with the rotary wheel and selection button.

Cosmic Wind T

Throttle Way Up for Fun on this Little Racer

he original Cosmic Wind was built by a group of Lockheed employees, including Tony LeVier. The project started in 1946, and three aircraft were built.

They were designed to compete in the 1947 Goodyear Trophy Race, which was held in Cleveland, Ohio.

The airplanes finished in third and fourth place. Later, in 1964, one of the three Cosmic Winds (Ballerina) finished in first place at the Kings Cup Race in the United Kingdom.

One of the original aircraft is now on display in the Experimental Aircraft Association’s AirVenture Museum in Oshkosh, Wisconsin.

Great Planes’ model of Cosmic Wind is a hot, little, lightweight, electric-powered and almost-readyto-fly (ARF) airplane that looks fast just sitting on the runway. It is the kind of model that anyone who likes handling quick, responsive models will get a thrill flying. I know I did!

In Flight

At the airfield, the wing was bolted on and the battery installed.

After doing a quick radio range check, the Cosmic Wind was ready to fly.

Ground handling is good on the pavement, but the tail wheel is pretty small, so unless you are taxiing it on a close-cut grass runway it would be a bit difficult to maneuver. However, once it was lined up on the paved runway at our airfield, I gave it power and it accelerated rapidly. It used only a short amount of runway before it was airborne. As is to be

This shows the Cosmic Wind coming down for a high-speed inverted pass above the runway.

Dropping one wing, I brought the Cosmic Wind down low above the runway for a photo pass.

This is how the kit looks out of the manufacturer’s shipping box. You get a fuselage, wings, stabilizers, canopy and pushrods.

This is the hardware needed to complete the kit. You’ll have to buy a motor, speed controller, battery, propeller, receiver and servos.

I flew the airplane up high to try a stall, expecting it to drop a wing, but it didn’t! Even holding full up elevator control, the airplane just “mushed” and then started to fall.

It did not drop a wing.

When I let its airspeed build again, it recovered quickly.

Great Planes Cosmic Wind

Assembly The Cosmic Wind is very easy to assemble. The build is covered in depth in the instruction manual. You will need a few tools and a little building experience, though.

Start by joining the wing halves. There is a hardwood wing joiner as well as an alignment pin. It is best to dry-fit the parts before glueing them in place because a little sanding may be necessary.

Next, I assembled the fuselage, beginning by attaching the landing gear, axles, wheels and wheel pants. Then the horizontal stabilizer was installed.

The important thing when installing the stabilizer is to get it glued in perfectly straight. If you have an angle finder, it is a very handy tool for this step. If not, you can either use a measuring stick/tape measure, or a piece of string to measure the distance from the front of the fuselage to each tip of the stabilizer, which will help you ensure that the stabilizer is properly aligned. Once you have it aligned properly I recommend you mark the stabilizer along the lines of the fuselage with a pen so you can re-insert it at the correct angle. Then you will remove the stabilizer and remove covering material from the fuselage/stabilizer contact area.

Then it will be ready to glue in position. However, you must make certain that the elevator joiner rod is inserted into the stabilizer slot before you glue it in place.

Then you can hinge the elevator and rudder. The kit provides cyanoacrylatetype hinges, which makes the install a snap. Next you will screw in the tail wheel bracket. It is a very simple process.

The next step is installing the motor and electronic speed controller (ESC). fun with this little racer. Also, the kit quality is quite good, assembly is very easy and the flight performance is great. Whether you are an intermediate or even an advanced pilot, the Cosmic Wind will put a smile on your face!

My Cosmic Wind is powered by a RimFire .10 brushless outrunner. The ESC is Electrifly 35-amp unit. The motor bolts in to the pre drilled firewall, and the ESC is attached to the side of the fuselage with Velcro®-type material.

Your next part of the assembly is to screw the control horns into the elevator and rudder. Then you’ll insert the pushrods into their housings. You must use a pair of pliers to create a Z-bend in the end of the pushrod, which connects to the control horn.

My Cosmic Wind is controlled by Futaba 3114 micro servos. You’ll connect them to the the pushrod by way of “EZ” connectors. The same method is used to install the aileron servo. The receiver is held in place by Velcro too.

The canopy is a well-made part and takes only a few minutes to mate to the fuselage.

You’ll finish your Cosmic Wing by installing the propeller and spinner.

The model’s center of gravity is called out in the manual as being 52-mm (2in.) behind the leading edge of the wing root. You’ll also want to program in the proper control throws, both high and low rates.

Overall, the airplane went together very well and the kit was complete. I did have to use a hobby knife to cut back a little bit of the plate holding the wing’s blind nuts because the control horns on the wing rubbed the plate. The battery access hatch also did not fit perfectly flush with the fuselage. Other than that, I was very happy with its assembly.

n the early years of aviation, the First World War (WWI) broke out in Europe. Airplanes were almost immediately put to combat use. American air power was next to nothing, while the British and French led the Allies against the juggernaut that was the German Luftstreitkräfte.

Allied pilots flying Sopwith and Nieuport biplane fighters engaged superior German Fokker triplanes and Pfalz biplanes over a lifeless noman’s land. The advanced German aircraft coupled with elite pilots made for air superiority in favor of

Albatros D.Va BNF A World War I Warbird for the Park Flyer Collector the Central Powers.

One of these war machines was the Albatros D.Va—an improved version of the successful D.III. The D.V was nearly identical to the D.III with the exceptions of its more elliptical fuselage and its revised aileron linkages that were contained

entirely within the upper wing. Much like the D.III did, the D.V began to experience significant structural failures in the lower wing in service.

These continued failures and the Flying the large ParkZone Albatros D.Va is both easy and fun, but it is not an aircraft for beginners to fly solo.

minute improvement in performance over the D.III caused pilot discontent, and famed ace Baron Manfred von Richthofen remarked that the D.V was “so obsolete and so ridiculously inferior to the English that one can’t do anything with this aircraft.”

Subsequently, Albatros reworked the D.V into the D.Va, which incorporated strengthened wing spars, a reinforced fuselage, heavier wing ribs and the addition of a 180hp Mercedes D.IIIaü engine in place of the 170-hp Mercedes D.IIIa. These improvements made the aircraft 50 lb (23 kg) heavier than the D.III, but slightly better to pilot than the D.V. The structural problems weren’t entirely resolved. As a result, the D.Va only saw service with the Luftstreitkräfte as an alternative to faultier Fokker Dr.I and Pfalz D.III aircraft until it was replaced by the Fokker D.VII. Note that Richthofen flew the D.V from late June to late July in 1917 before switching over to his famed Fokker Dr.I triplane. During that month, Richthofen was shot down in his D.V near Wervicq, Belgium

by British ace Captain (Capt.) Donald Cunnell in an F.E. 2d after Richthofen engaged Cunnell’s formation.

would require multiple surgeries to remove bone splinters from the injury site. It is theorized that the wound was to blame for his postflight nausea, headaches and change in temper following the incident.

Cunnell was killed days after his victory over Richthofen.

The incredible detail put into the Albatros D.Va complements the aircraft in flight, as even the pilot’s scarf dances in the breeze.

Model Albatros D.Va

The ParkZone Albatros D.Va bind-n-fly (BNF) comes as an airplane that is molded from Z-Foam™. It is lightweight and durable.

The kit arrives double-boxed for safe transit during shipping.

Foam packaging neatly organizes the parts and pieces and adds further protection against damage.

The kit comes nearly ready to fly, but there are a few pieces that must be assembled. It is easy to do, and the result is an attractive, strong model.

The D.Va comes painted in the colors of an early, unfinished scheme worn on the D.V that was piloted by infamous German ace Manfred von Richthofen, better known as The Red Baron.

I found that when you apply the throttle progressively the model tracks quite straight down the runway. The rudder control was exceptional for a park flyer of this size. You’re going to like the power the 480-size motor provides too.

The 10 x 8 propeller delivers enough thrust for steep climbs and some moderate, but very fun aerobatics. I found that the model loops well. It does rolls too. Inverted flight is best done very high because this model is not made for it, and it will fall out of the sky. You’ll enjoy doing some strafing runs on the enemy—your

flying buddies and their airplanes. The big wheels provide for nice touchand-go landings too.

Another thing I found enjoyable about my Albatros D.Va is that its ParkZone 1800-mAh 3S 11.1-V LiPo battery delivers great flight times. I was surprised by the length of the motor run time. My only regret is that I did not buy an extra battery.

One will be on order soon!

Debrief

I think it is fair to say that the ParkZone Albatros D.Va is a very good buy. At a price of $239.99 and

ParkZone® Albatros D.Va BNF

Assembly As with most ParkZone kits, the assembly of the Albatros D.Va is simple.

As I do with all of my builds, I follow the instructions in the manual. In this case I began by attaching the wing—the lower wing first. Common to ParkZone aircraft, a mounting plate on the fuselage guides the front of the wing into a neat and secure fit. The rear of the wing is then fastened in place with a pair of 3 x 10-mm screws that mount to the rear of the fuselage.

Next, the fixed landing gear was assembled. An axle must be slid into both left and right landing gear covers. A pair of simulated shock absorbers are mounted to the inner sides of each gear cover. They are a bit tricky to assemble but fit well once figured out and mounted. A wheel spacer is then put on the end of each axle, followed by the wheel and a wheel collar that is locked in place with a setscrew. The landing gear is then fastened to the bottom of the fuselage by eight 2.5 x 8-mm. screws on top of the left and right, front and back plates that secure the gear to the fuselage. Easy stuff.

Installing the upper wing is even easier. You’ll begin by attaching left and right cabanes to the wing. They rock into place on a set of brackets that lock them in but allow some free-play you’ll need for alignment when attaching the wing to the fuselage. A pair of servo leads hang from the center of the wing and attach to

an assembly time of under an hour, it is one of those little park flyers that you really should consider putting in your hangar. One thing is for certain: it is a good-looking WWI fighter aircraft in the air.

the Y-harness that runs to the receiver. You’ll fasten the cabanes to the fuselage with four 3 x 10-mm screws that go into prepunched holes in the fuselage.

A pair of L-brackets rock into mounting plates on the lower wing to form the interplane struts. Once rocked into position, the struts align with mounts on the upper wing and are fastened together by a long retainer pin. That completes the wing assembly.

To finish the empennage, you’ll mount the horizontal stabilizer to the fuselage. The stabilizer slides into a precut track in the rear of the fuselage. It tightens securely once it is completely forward. Not much force is needed, so be mindful of your strength. The stabilizer must fit with the elevator control horn when it is facing downward to meet the clevis at the end of the servo pushrod.

There is an option to install either a tail wheel assembly or a tail skid. My model uses the tail skid, which lets me avoid cutting away the parts of the rudder as well as removing and reinstalling the rudder control horn. To mount the tail skid, you only need to align the skid to the tail assembly and secure it with the four 1.5 x 8-mm. screws.

All in all, the Albatros D.Va is an easy build.

PEACE OF MIND

“Starts and idles like a dream.

Throttle transitions are crisp and without hesitation.

I think we have a winner here.”

– Dino DiGiorgio, Top Gun Winner

ZPENGINES.COM

NEW ZP ELECTRONIC IGNITION ENGINES Dino DiGiorgio doesn’t build models. He builds masterpieces. For him, dependability and ease of use are as important as power when choosing an engine. That’s why he had no trouble trusting this beautiful Focke-Wulf to a new ZP Platinum 62cc engine. ZP engines are built using the same core components as the Zenoah™ magneto engines he and other scale masters have relied on for years.

HORIZON HOBBY

One of the best features of a ZP engine is one you won’t find in the box—the unbeatable service of Horizon Hobby product support. You’ll probably never need it, but knowing the best team of product support pros in the business has your back is just another reason ZP engines are one of the greatest values in RC.

What sets ZP engines apart is an advanced electronic ignition system that makes them incredibly easy to start and operate. It also eliminates the weight of magnetos and a bulky PTO shaft. This, along with their abundance of torque, is why ZP engines are able to deliver remarkable power-to-weight performance using a variety of props.

The new era of gas engine simplicity and power is here. Get to ZPENGINES.COM right now to learn all about it.
