Both Friday and Saturday, pilot meetings were conducted by Metz and Seddon to familiarize the pilots with the field procedures and safety equipment and explain how to earn tickets for the big pilot raffle. The raffle was organized so that a pilot was given a ticket for each flight, encouraging him to fly more times over the weekend. Each day after the pilot meeting, the National Anthem came over the PA system, accompanied by an astounding demonstration of formation flying by the Horizon Hobby Team. The team members,

DECATHLON FUSELAGE THE WOODWORK IS ABOUT CRAFTSMANSHIP BY JEFF TROY

constructing your own favorite models. I use Bob Smith Industries (BSI) Insta-Cure + medium CA (cyanocrylate) glue for most of my models’ basic construction. InstaCure thin CA and Maxi-Cure thick CA are also used where needed. When epoxy is called for, BSI Quik-Cure (5

minute), Mid-Cure (15 minute), and Slow-Cure (30 minute) epoxy are my choices. Before the model can be covered, it’s important that no rough edges, high spots, or low spots are present in the woodwork. High spots will cause lumps in the covering. Low spots will result in valleys where there the covering is unsupported. Rough edges can cause snags in the covering and prevent it from shrinking correctly, most often at joints between stringers and bulkheads, as well as where ribs meet leading and trailing edges, spars, and sheeting. If you’re building something—not necessarily the Decathlon—along with me, you’ve already block-sanded the fuselage with medium to coarse sandpaper on the Easy-Touch Bar Sander from Great Planes®. Block sanding does a nice job of eliminating high spots and ridges, but something more is needed to fill valleys and gaps in your model’s joints. I use HobbyLite from Hobbico, which is available in your choice of two colors: white and “balsa,” which is a pleasing shade of medium tan. Before applying HobbyLite, it’s wise to clean up any rough edges twitter.com/rcsportflyer

Remove any fuzz, splinters, and blemishes from the model’s LitePly parts. My favorite tool for this kind of edge dressing is the Sanding Pad Dual Grit 120/240 from Stevens AeroModel.

I use HobbyLite filler to bridge any valleys and minor gaps in my models. For optimum penetration and adhesion, dab the area with tap water just before applying the filler.

The coarse — 120-grit — side of the Stevens Dual Grit pad is ideal for taking down the filler. Flip it over to feather the edges of the filler into the wood.

that may still remain on your model’s Lite-Ply parts. Blemishes in the cabin area are the most obvious in the window perimeters and wing saddle. These blemishes are generally in the form of fuzz or small splinters created when the die-cut parts were removed from their sheets. Coarse sandpaper can gauge these edges or remove too much material, so I use the coarse (120 grit) side of the Stevens AeroModel Sanding Pad Dual Grit 120/240 to dress Lite-Ply edges after block sanding. Get a feel for using the sanding pad by lightly dusting the edges of the wing saddle; then you’ll see how nicely this tools works and how easy it is to master. Next, work the sander around the inside and outside edges of the window openings, applying only light to medium pressure. The object is to remove any fuzz and jagged edges without altering the rc-sportflyer.tumblr.com
hard edge of the opening. After a few minutes with this amazing tool, you will have become a sanding-pad expert, and will most likely never build another model airplane without having one or more of these pads on hand. HobbyLite is a pleasure to use, and you’ll love the results. It’s soft, dries quickly, and sands easily. You can apply it directly onto the surface, although I like to treat balsa and other porous surfaces with a dab of fresh water before wiping on the filler. Doing this helps the filler penetrate the grain of the wood and increases the bond. I keep an open jar of water next to the tub of HobbyLite, using one finger to wet the surface being filled, and another finger to apply the filler. You might also want to use the water finger to help smooth the filler over the surface as it’s being applied. Just remember that the filler
must always dry at a level above the surface. Sanding is what brings it flush. Unless it’s heavily applied, HobbyLite will dry within a few hours. You can test it with a light dusting of the Stevens sanding pad. If the filler takes down smoothly, you’re all set, but if it starts to load the pad, wait an hour or two longer and check again. When it’s dry, sand with the coarse side of the pad to bring the filler level with the surface, then use the fine side to smooth the job and feather the edges so they can’t be detected under the model’s film or fabric covering. Each Decathlon V-strut is made from two pieces of airfoil-shaped wood. Holes must be drilled for the mounting hardware, and the individual struts must be joined at the base to form the V. Begin by drilling a 1/8-in. hole on one end of each of the four lengths of strut material, then threading a nylon strut-mount RC-SF.COM

The first 195 prototype flew in 1945, and it entered production in 1947. The 195 was Cessna’s first all aluminum airplane. It features a cantilever wing. The wing planform has a straight taper from root chord to tip chord, and it has no dihedral. The airfoil employed is a NACA 2412. The 195 has two seats up front, with three passengers accommodated on a bench seat in the back. The 195 has flat sprung-steel landing gear legs. Many were equipped with swiveling crosswind

HOW TO
FIREWALLS
MAKE IT REMOVABLE TO MAKE IT EASY BY ROBERT CASO

This is the nose of the Bulldog with blind nuts mounted in a circumferential ring to accommodate the firewall. A centering ring was also fabricated.
C
ertainly, by now you should know that I am a big proponent of electric power for RC scale models. Electric motors are compact, clean, powerful, reliable, and vibration free, all of which are critical elements for a flying scale model. My Mosquito and DH2 for example could never have been successful and field friendly models with other than an electric motor — and the combinations available today in terms of motor, propeller, electronic speed controller (ESC), and batteries are almost limitless. Nevertheless, I am always searching for ways to make my models more scale and easier to work on. This goal oftentimes requires models to be designed at the outset to eliminate non-scale features such as exposed linkages and equipment access hatches or panels. While not really a new idea per se, I have started using removable firewalls on my electric models to help accomplish this goal.

Here is the plywood firewall plate that mounts to the nose. It is shown prior to the installation of the airplane’s box-shaped motor mount.
With such a design feature, the model’s front end essentially becomes a power unit, and would incorporate the motor and its mount, the ESC, attachment points for the cowling and dummy engine, and a flange for mounting the unit to the model. There are a number of benefits here that take advantage of a motor’s characteristics noted above. First, without significant vibration, there is little risk of the power unit parting company from the model. Once removed from the model, the open area on the nose becomes a hidden equipment access hatch for batteries and servos. This area also makes a model easier to fit out during construction, allowing the insertion of pushrods, scale cockpits, landing gear and other critical items. A useful byproduct of this design is that it also allows you to change your mind. Let me explain. Although I use Motocalc to determine the power needs of a given design, a critical input to Motocalc is airframe weight.
I have the bad habit of constantly underestimating what this will be, which in turn requires the installation of a larger motor, batteries and ESC. Sometimes too, I simply decide that I want to use a different motor, for whatever reason. If the motor mount was designed to accommodate the initial selection has already been permanently affixed to the airframe, I’m looking at a major redo of a critical area on my model. Not so with a properly designed removable mount. With the latter, it is simply a question of making a new mount to accommodate the change and affixing this to a plate that already fits the model. Done! An excellent case in point is my recent 51-in. Bulldog. Early on, I estimated the flying weight to be three and one half pounds and selected an appropriate motor to power it. What was I thinking? The final weight was north of five pounds. Thankfully, I recognized this when I was well into the build as I was twitter.com/rcsportflyer

At this point, the plywood firewall plate has been test fit to the nose. The rectangular holes for servo pushrods were later eliminated.

slathering on layer after layer of fiberglass and filler. Although I had good cause to believe the model would fly at this weight, I nevertheless had to up-gun the motor selection. rc-sportflyer.tumblr.com
The new motor was slightly larger in footprint, longer and had a different propeller mount. Since I had already employed the power unit concept in the original design of the model,
ultimately this change was no big deal. Had I used a traditional construction methodology, I would have had a real mess on my hands. Using the Bulldog as the guinea RC-SF.COM

fellow modeler once said, “If it looks good it will fly good!” That is certainly the case with the new Hangar 9 Valiant 33-cc-powered, high-wing, monoplane. It has good looks and performance to spare, with an affordable price tag that nearly any modeler can fit into their budget. When this model landed in our office I was immediately drawn to the design from the box art. Then when I opened the box I knew this gas-powered model would be one I’d want to review. It has all the fit and finish of the typical Hangar 9 almost-ready-to-fly (ARF) airplane, plus the gas-powered engine meant
affordability and performance. Throw in the Spektrum servos, receiver, and batteries and you have a winning combination. What you’ll discover is that the Valiant can be powered by an Evolution 33GX engine or by an E-flite Power 160 motor. Also, there is an option for tundra-style landing gear and balloon tires, or you can add floats to fly it off water. Plus, the engine’s igntion can be run on a two-cell LiPo packs, as can the high-voltage servos. That means radio setup and ignition are easy to do, which is a time saver! It certainly seems that Hangar 9 was thinking outside the kit box on this monoplane.

T
he RC 3D helicopter craze continues to grow, which is a huge positive for pilots everywhere. It was not so long ago that it required a very special skill set to fly an RC helicopter, which were quite difficult to master. Today most RC pilots can make the leap from winged flight to rotors without a lot of damage and/or broken parts in their wake thanks to advanced stabilization technologies.
The popularity of 3D helicopters also makes for many choices in machine brands and sizes. Previously the rotor world was dominated by the 600-size helicopters, where the machines’ rotor diameters measured roughly 600 mm in length. Today a standard size seems to be the 700, with a few 800 versions now gaining in popularity. In addition to these larger sizes, other helicopter versions continue to get smaller, and way more powerful than ever. The smaller machines have been dominated by the 450 size. Note that there is no standard small size thanks to the evolution of batteries, motors, and most of all, the stabilization systems we typically refer to as gyros. BladeŽ offers helicopters in almost any size as a way to fit the needs of rotor pilots. One of their best offers in the micro-size is the 180 CFX.

stunts, or gently fly in circles if the pilot chooses — powered by a 3-cell LiPo battery. Moreover, this little helicopter is an entirely new design, not a new face on an older version, so be ready to be astounded. IN THE AIR Flying the Blade® 180 CFX is amazing! For such a small helicopter it is not only more stable than I would have thought, but it is also extremely agile and quick. Taking off in normal mode, and hovering a few feet off the ground to avoid the cushion of air we refer to as ground effect, the 180 CFX holds its position very well. A quick switch flip to Stunt 1, and then the most aggressive Stunt 2, and I was off and away to a great time zipping around the sky with the 180. One quick note to those who may not be aware, stunt mode means the rotor head speed is mostly constant. The main rotor changes pitch and goes full positive when the throttle

is pushed up and the pitch goes full negative when the throttle is lowered. The helicopter will hold its altitude position at someplace around the mid-throttle settings, but lowering the throttle will not lower the rotor speed. Only switching back to normal mode will allow that to happen. I suggest you take it off in normal mode and once a stable hover is established around a mid-stick position on throttle, simply flip the stunt mode switch for the extreme flight capabilities to shine. Most pilots switch back to normal mode for landings, so the rotor head speed will slow when lowering the throttle. After flying around in stunt mode, getting back into normal mode is simple, requiring the stick to be someplace around mid-level, and just flipping the switch back to normal mode for control of pitch and rotor speed to work together again. This little helicopter is smooth, and capable of flying away very fast if pitched forward while at full power.
Check out the side frames, landing gear, swashplate and battery pack. They are all high quality, and make for a helicopter that you can put thru its paces.
It is amazingly fast actually, and will cover lots of ground quickly. There isn’t anything the Blade® 180 CFX cannot do either as far as I can tell. I fly a little aggressively but I am by no means a skilled 3D pilot, though I have witnessed some simply amazing flying with this helicopter in its stock configuration. Inverted flight is a no-brainer, and tic-tocs, funnels, and about anything you can possibly imagine can be done when flown by the right pilot. Expect about three-minute flights to start, and then work your way up depending on how the battery performs for your piloting style. If you look online at some of the great videos available, three minutes will give plenty of time to fly some amazing aerobatics. Check out this one from a team Horizon pilot: youtube.com/ watch?t=54&v=BuU4xmQj52A Let me tell you a quick story. One day a guy was walking his dog around the local park. He saw my 180 CFX

he F4U Corsair was a superb fighting machine during WWII. It was loved by its pilot because it had plenty of power from its 2800-cubic-inch big, radial engine, was nibble in the air for air-to-air combat, had lots of firepower from rockets, 50-caliber machine guns, and bombs, and was armored well to protect the pilots from enemy fire. It is probably most noted for its performance while in the capable hands of the Jolly Rogers, and was flown by the fighting forces of both the U.S. Marines and Navy — coming to aircraft carriers late in the war after British pilots perfected deck landings. Now, the F4U Corsair is most seen in aviation musuems and rarely at an airshow like the one at Oshkosh, Wisconsin.
