Detailed Instructions 1.) What’s in the box: Opening the box you should see: a.) Total G itself b.) USB cable c.) USB adaptor d.) Two external receiver wire cables e.) “Y” harness power adaptor f.) Four double stick tape pads g.) G‐10 Sensor mounting bracket h.) Two Velcro straps
2.) Wiring of the Total G: First you have two main options for setting up the control of the Total G either using Satellite receivers such as Spektrum satellites (remote receiver). Or using an external receiver plugged in using the external receiver wires.
JR/Spektrum Wiring: RPM – plug for the RPM sensor for the governor THRO – plug for your throttle servo or ESC AIL – plug for your Aileron servo (CCPM ‐ Servo 1) ELEV – plug for your Elevator servo (CCPM ‐ Servo 3) RUD – plug for your rudder servo COL – plug for your Collective Servo (CCPM ‐Servo 2) PWR/BND – plug in power to the Total G here. For extra power connections you can also “Y” in power into any of the plugs except the EXT 1 and EXT 2 plugs. You can also plug in power to the programming plugs on the top, just orient the plug so the ground wire (brown) plugs into the pin closest to the servo plugs. Secure any loose wires to prevent excess vibration. EXT 1 – matches AUX A in the interface for hooking up external devices. Note – power for external devices has to be “Y” harnessed in from a separate plug. EXT 2 – matches AUX B in the interface for hooking up external devices Note ‐ Aux channels such as Gear, Aux 2, Aux 3 , Aux 4, etc… These channels are all internal to the Total G and do not need any external plugs. These channels can be accessed inside the Total G for programming and adjustment. Do not need to look for a port, these are internal.
External devices – For example a SwitchGlo To hook up remove the signal wire (yellow or white wire) from the standard plug and put the signal wire into a new plug end. It can be removed from one of the external receiver wire adaptors included in the Total G. Then plug the signal into EXT 1 (or EXT2), and the plug that still has the power wires plugs into the top 4 pin programming plugs. Just have the ground (brown or black) wire facing toward where the servo plugs go in. These top programming pins are on the same power bus as the servos so they get the same power as the servos. So you can also bring in power to the unit there.
External Receiver Wiring: RPM – plug for the governor RPM sensor THRO – plug for your throttle servo or ESC AIL – plug for your Aileron servo (CCPM ‐ Servo 1) ELEV – plug for your Elevator servo (CCPM ‐ Servo 3) RUD – plug for your rudder servo COL – plug for your Collective Servo (CCPM ‐Servo 2) PWR/BND – Plug in the “Y” harness here for power. For example with futaba you could plug this into channel 7. So from your transmitter Channel 7 would control “Gear” within the Total G. This plug supplies power to both the Total G and the Receiver. If you need to drop down the voltage to the Receiver you can use a voltage drop down in this connection. Just make sure the drop down carries the signal wire. EXT 1 – Plug in the external receiver adaptor wire. Thro/Elev/Col. The orange wire on this adaptor plugs into the throttle channel in your receiver. The red wire plugs into your elevator channel. And the brown wire plugs into the collective channel in your receiver. EXT 2 – Plug in the second external receiver adaptor wire. Aux2/Ail/Rud. The Orange wire plugs into the channel you want to control “Aux 2”. Many Futaba users plug this into channel 5. So channel 5 now controls “Aux 2” within the Total G. The Red wire plugs into the aileron channel in the receiver. The brown wire plugs into the Rudder channel in the receiver. **Note ** – with external receivers you only have access to two “Aux” channels. These two Aux channels are labeled “Aux 2” and “Gear” within the Total G. These two channels can be assigned and used within the Total G to control several items. Normally “Aux 2” is assigned to the gyro (or flight control) and the “Gear” is assigned to the governor. For adjusting a third channel you can set it to “G‐view” and manually adjust its value in either the computer interface of the G‐view2 (available separately)
3.) Installing the Total G: 3a.) Mounting the Total G ‐ The Total G should be mounted as tight as possible for best performance. This is true for both Nitro and Electric machines. The suggested mounting is one layer (two pieces side by side) of the supplied doubled sided tape. The Total G must be mounted perpendicular to the main shaft with two sides of the Total G squared relative to the frames. It can be mounted top up or upside down as long as it is squared up to the frames. If the unit is not square the machine may not flip and roll straight. This can be corrected using the Roll and Flip mixes if needed. It is also important to tie down the wiring to prevent vibration from getting into the Total G. You can also use the supplied Velcro strap to add extra safety in flight.
For JR/Spektrum you want to run at least 2 satellites for anything smaller than a 50 size (600 size) machine. And you want to run 3 satellites on anything 50 size or larger. The rear satellite plug is the “Primary” satellite so this unit must have a satellite when used in Spektrum mode or the unit will not function.
3b.) Mounting the RPM Sensor ‐ The RPM sensor can be mounted in several different ways.
To the clutch, engine fan or tail takeoff unit. Which you choose will simply change the gear ratio you choose in the governor setup. The images below show examples of several different installations. The Total G comes with a “universal plate” that can be trimmed and used in many different locations depen ding on your model and mounting.
4.) Installing the Computer Interface: The computer interface can be downloaded on www.curtisyoungblood.com from the Total G resource page. Download and install the program. The software should download or direct you to the appropriate downloads automatically. If that does not work for some reason, you can download the supported .NET software from Microsoft for the interface from: Microsoft .NET Framework 4 (Web Installer) Again, with newer versions of Windows, the FTDI drivers for the USB dongle should install automatically. This appears as a prompt for windows to search the internet for drivers. Allow it to. If it does not find the drivers for you automatically, please use the “specify a location” feature of the windows driver install process, click browse and navigate to this location: C:\Program Files\CJ Youngblood Enterprises\TotalG\FTDI\ If none of this works please contact us at firstname.lastname@example.org for support with your system.
5.) Powering on Total G and Interface for the first time: Once the interface is downloaded follow the steps below to start using the interface: 1.) Click on the program interface to start the program 2.) If you are using JR Spektrum satellites go to step 4.) . If you are using an external Receiver – turn on the Total G and plug in the USB cable to the flight control plug. Then click on the helicopter in the top left corner of the interface. A dialog box should come up giving you the option to set the radio type. Set it to external receiver. 3.) Turn off the Total G. Go to step 5.) 4.) The Total G defaults to Sepktrum satellite mode. But you still need to Bind the satellites to your Transmiiter. Binding ‐ to bind the Total G in Spektrum mode, plug a “bind” plug into the “Pwr/bnd” plug (7th plug from the right). Then plug in power to the Total G. I plug in power to one of the programming plugs on the top for binding (photo of top of Total G). So power on the Total G and you should see the satellite LEDs flashing. Then turn on your transmitter while holding the bind button on the back of the transmitter. Once the transmitter is on, release the button on the radio. The satellites should flash for a short period of time then go to a solid light. This indicates they have bound to the transmitter. If they turn off then try again. If repeated attempts do not work, remove the satellite that is plugged into the back of the Total G and replace it with a different one and try again. You may have a faulty satellite. 5.) Turn off the Total G and transmitter and remove the bind plug. Then return the power plug to the normal PWR/BND location. 6.) Turn the Transmitter and then Total G back on. 7.) Wait until the Total G yellow light comes on, indicating it is initializing, and then goes back off. Once the Yellow light is off the Total G is ready to program.
If a Red light stays on and does not quickly go to yellow then the Total G is waiting on a signal to come in. Indicating something in the radio setup is not correct. Either satellites are not bound properly or the external receiver is not hooked up properly. Note‐ it will also stay red when you are in the middle of bootloading a new program – discussed later. 8.) With the USB cable plugged into the Total G, click on the helicopter in the top left corner of the interface to connect to the Total G. A connection status bar should appear.
6.) Interface Notes: 6a.) File Load from file –This downloads a file of parameters to load directly into your Total G. Just select “Load from file” and select the appropriate file. All your parameters will be updated to the loaded file parameters. So once you have uploaded the file, go back through your basic setup to get all your limits, gyro directions, etc to make sure it is setup to your specific model needs. Models can be saved from other Total Gs or downloaded from other locations like http://www.CurtisYoungblood.com Save To File – Saves the current connected Total G settings to a file. Note ‐ Flight control and tail gyro/governor settings are saved separately but can be in the same file. You have to connect to the plugs separately and save separately, but they can be saved to the exact same file to keep all the model parameters together. Load from Total G ‐ Loads the parameters from currently connected Total G. This is useful if you have “Options > Automatic load from Total G” unchecked. Check for updates – click to check for updates. A dialog box will come up indicating whether updates are available. Exit – Used to disconnect and exit the program. You can also disconnect the program from the Total G by clicking on the “Connect” button (image of a helicopter) in the top left corner.
6b.) Comm This shows the available USB comm ports. If you have the drivers installed correctly a comm port should show up when you plug in your USB. The interface should automatically select the correct comm port. If it does not try unplugging and replugging the USB cable from the computer and trying again. As long as you keep using the same cable, USB adaptor and USB plug, the program should pick up the cable every time you plug it in. In some cases the program might have issues connecting to the correct “Comm port”. This can happen if you have several comm port options. To track down this issue, first go up to the “Comm” on the top menu bar and see if the option “Auto” is available. If it is then select it and try connecting again. If you are still having issues connecting, make sure that a new “Comm port” option appears in the “Comm” drop down menu when you unplug and then replug in the USB adaptor. If it does not then there might be a driver or USB issue Note – if you hook up new USB cables and adaptors the interface will show and hook up on new Comm ports.
6c.)Programming This menu shows you your programming page options. The check mark is on the presently loaded page. Note ‐ the Total G will automatically load the “Radio Setup” page if you are plugged into the flight control side. And it will automatically load the “Tail Rotor/Gov” page if you are plugged into the Tail/Gov side. The unavailable page will be grayed out. Radio setup – is the main flight control programming page and it automatically loads when you connect while the USB adaptor is plugged into the 4‐pin “Flight Control” plug on the top of the Total G. Explanations for setting up this page begin in section 7a.). Background Settings – These setting are the more advanced settings that should be thought of as being in the background and should only be changed with caution as several of these settings can result in oscillations and possible boom strikes in the air if adjust incorrectly. See Section 7b.) for details. Tail rotor/Gov – this page loads automatically when you connect while the USB adaptor is plugged into the 4‐pin “Gyro” plug on the top of the Total G GView – this is a simulation of the G‐view2 itself.
Bootload Firmware – This is selected to load new firmware to the Total G. To bootload you first need to select the program to load. The newest version is listed on top. Then click “Start”. You will get this warning, asking you if you wish to proceed. Click “YES”
Wait 5 seconds before doing anything else
You will now be prompted to power cycle the Total G to get it into bootload mode. Power the total G off and then back on before you click “OK”. If you click “OK” first you might cause an error in the bootload. When you power the Total G back on the Red LED should be on indicating it is waiting on a signal. If the red light is on hit the “OK” button in the window as prompted earlier. You should see the status bar come up indicating the bootload status. Once it is complete you should see a message box as below indicating the firmware bootload is complete.
Power cycle the unit twice to complete the firmware install. It will not work properly until cycled twice. The Total G should now work as normal. All your previous settings in the Total G should not have changed. You should not have to reset any of your basic model settings. But it is a good idea to confirm the unit is operating properly before flying.
6d.) Options The interface comes default to upload all the parameters everytime you connect. To speed up opening the interface window, click off the Check mark beside “Automatic Load From Total G”. The Interface will open with all the parameter boxes empty and you can go highlight the one you wish to adjust. If you then want to get all the Parameters just go under “File” and click “Load from Total G” and it will load all the parameters.
6e.) Help This section has the Help Documentation and “About Total G” listing. The help documentation can also be access for each individual parameter by right clicking on the parameter. Right click on any parameter to reset to default(factory default), reset to original (means the original number you had when you connected this time) or access the Help documentation for that parameter.
6f.) General Interface Details 1.) Missed frames – top center of the page Missed frames indicated the number of missed signals the Total G has received from the satellites. The first “0” is a slot for the number of individual misses. The second “0” is a slot for 2 misses in a row. The third “0” is for 3 misses or greater in a row. For example (7 1 3) , would be 7 single misses, 1 double miss and 3 triple misses. Of course a higher number of triple misses is worse than the same number of single misses. Often misses here can be tracked down to satellite or satellite wire issues.
2.) Magnet – top center of the page To check the magnet sensing, move the cursor over the Red dot and move the magnet near the sensor. The dot should turn Green
3.) Version This lists the presently uploaded version of the firmware.
4.) Radio This tells whether the Radio is ON or OFF.
5.) Serial # This is the serial number for the Total G itself. Tech support might ask for this number if helping to trouble shoot issues.
6.) Radio Type
This selects whether you are using the spectrum satellite receivers or an external receiver. This must be set for the unit to function properly.
7.) TX Type This is a choice between JR and Futaba to take into account their different “neutral” input pulse width settings. JR centers around 1500 and Futaba around 1530. Select the “Type” that most closely fits your radio gear. If in doubt leave it at the default “JR” setting.
7.) Interface Programming (Flight Control Side) Basic use of the interface – you cannot set any parameter in the Total G until you highlight it in yellow first. Only highlighted items will update. This includes checking the magnet sensing and watching Channel signals change. Also all parameters change within the Total G when you change them on the interface. You do not have to do a “Save” to store the parameters.
7a.) Channel Assignments – used to assign Gain and EXT channels. Also shows input pulse width for each channel selected so you can confirm channel changes are working.
FC Gain – select the channel you want to control the FC gain.
With Spektrum AUX 3 is a common choice. With an external receiver either Aux 2, gear or G‐view are common selections.
Gyro Gain – select the channel to control the tail gyro gain. With Spektrum Aux 2 is a common choice. With an external receiver Aux 2, gear or G‐view are common selections.
Gov RPM‐ select the channel to control the governor RPM. With Spektrum Gear is a common choice. With an external receiver Aux 2, gear or G‐view are common selections.
Aux A – This is assigning a channel to control the EXT 1 plug for the Total G if you are assigning it to control something external to the Total G. Note power for something plugged into the EXT plugs will need to be “Y” harnessed in from something else.
Aux B – this is assigning a channel to control the EXT 2 plug for the Total G if you are using it to control something external to the Total G.
7b.) Channel IPW (Input Pulse Widths) – This is the signal coming to the Total G on each channel. Use it to check the function of each channel
Throttle – throttle input signal
Aileron – aileron input signal
Elevator‐ elevator input signal
Tail rotor – rudder input signal
Gear – on spectrum this is the gear input signal. On an external receiver this is the channel that is plugged into the Pwr/bnd plug on the Total G
Collective – Collective input signal
Aux 2 – on spectrum this is aux 2 input signal.
On an external receiver, this is controlled by the channel that the orange wire coming from the “EXT 2” plug is plugged in to.
7c.) Misc – Here you can check your flight control gains along with the transmitter and gyro neutral shifts. Max Gain – This acts differently if you assign an AUX channel to control FC Gain or if you select “Gview” to control it. When the channel assignment for FC Gain is set to an Aux channel (for example Aux 3) the “Max Gain” acts as a limiter to prevent you from running the gain to an unsafe level with the Aux Channel. You can read the present FC Gain in the box directly below called “FC Gain). When the Channel Assignment is set to “G‐view” the “Max Gain” is now your actual gain setting. You run the number up and down with the arrows. And the “FC Gain” number will match the “Max Gain” when highlighted.
FC Gain – as mentioned above, it is your present FC Gain level. It will read what channel is controlling the Gain (for example Aux 3). It also indicates what mode you are in, whether Decay mode “D” or Trim lock mode “T”. The final item is the gain level itself.
Ail Ctrl – aileron control. This shows you how the “T”‐transmitter position and “G” gyro position have changed since the unit was initialized. 0 – indicates no change at all. 10 or below indicates a minor change in neutrals for the transmitter or gyro and may show up on the bench as a slow drift, but you should not see any issues in the air. Consistent levels of 15 or higher on either reading or a reading that jumps around erratically can result in noticeable drift or problems in the air. If “T” has high numbers that indicates the transmitter may have a bad pot or other issues. If “G” has a high level that indicates the gyro has drift and may need to be, either recalibrated (contact tech support for calibration instructions) or possibly replaced.
Elev Ctrl – is the same as Ail Ctrl simply for the elevator control and gyro.
7d.) Flight Control Setup 1.)Swash Mode With swash mode, select the swashplate type you are using, whether 120, 140, or Standard Mixing. When using 120 and 140 all the CCPM mixing is done in the Total G. So set your transmitter to “Standard Mode” (non‐CCPM mode). You can also select to turn off the flight control side of the Total G and use it in “Flybar” mode. In flybar mode all the internal CCPM mixing is turned off and the signal is simply passed through allowing you to use your transmitter for all the control mixing like a regular receiver. In flybar mode the aileron and elevator gyros are also turned off.
2.)Collective Direction Collective direction tells the flight control which direction is positive and which is negative. Highlight the tab and move to full positive collective. Then hit the up arrow. It should now say “Positive”. Then move the collective to full negative and confirm it says “Negative”
3.)Servo Direction and Neutral This section is used to reverse the individual cyclic servos in CCPM mode as needed. You also use it to do fine tuning of the servo neutral at center collective. First test the servo movement with control. Move collective and cyclic to confirm the servos are moving together as needed. Confirm when you give collective all the servos move the swashplate either up or down together. Then check aileron and confirm Servo 1 and Servo 2 move together to “Roll” the swashplate. Then check elevator to make sure the controls move together to “Flip” the swashplate (Servo 1 and servo 2 move together and servo 3 moves opposite). Reverse the servos here as needed to get them moving together. Once they are all moving together, confirm the actual function direction is correct. In that right gives right, forward gives forward, etc… To fix an incorrect function direction you can reverse the control in the transmitter.
4.)Orientation Select the orientation of the Total G. If the plugs are pointing parallel to the tail boom then select HrzBkfrnt (horizontal back front). If the plugs point perpendicular to the tail boom the select Horz Side (horizontal Side to Side). This will properly match the terminology for the Aileron and Elevator gyros.
5.)Flight Control Limits Flight control limits is where we teach the Total G the maximum input it can give during flight to control the model. To set the limits: 1.) Highlight the “collective” under the Channel IPW settings and move the collective to 1500. 2.)Use a pitch gauge to confirm you are at Zero degrees collective. 3.) Move your ATV's or END POINTS on your radio to maximum for aileron, elevator (for example JR 150/150 and Futaba 140/140). 4.) Now under flight control limits, highlight (make it turn yellow) the parameter for the right limit. 5.) Use a pitch gauge and confirm you have +‐11° cyclic without binding. If your system has too much cyclic turn down the radio ATV as needed. ATV should be somewhere between 100 to 150. If it is not enough travel with full ATV, increase the Travel Adjust (advanced menu) in Total G or change the head geometry. 6.)Once you confirm the correct cyclic, set your flight control limits in the Total G. For example; to set the “Right” limit highlight the right limit, hold full right control and hit “Set”. Repeat this for Left, Back, Forward. 7.) Once the limits are set, move your ATV's back to 80/80 for aileron and elevator. You will use your ATVs to set your total control rate. 80/80 on the ATVs is a conservative setting. For faster control go higher on the ATVs. Note‐ Collective is set separately. Simply set collective ATV as needed for desired throw. Often +‐ 12 on collective is good. Collective ATV does not need to be reduced along with the aileron and elevator.
6.) Gyro Directions Gyro direction is where we confirm the gyro is functioning in the proper direction. To test, tilt the machine forward and confirm the swashplate tries to stay level by tilting back. Do the same for back, right and left. In each case the swashplate should move to try to stay level. If the swashplate moves with the machine instead, then hit reverse on that gyro. Note – for safety it is good to do this tilting test (not needed to be hooked to the computer) at the beginning of every flying day. It should always stay the same, but it is a good quick test before flying.
7e.)Special Functions 1.) Trim Lock Trim Lock is the heading hold version of flight control. If it was not for Landing and taking off you could keep it in trim lock all the time. But the heading hold could tend to tip the machine over on takeoffs and autorotation landings. So we have a point where we want to turn on Trim Lock. “Throttle” is the most common option. With throttle, trim lock will turn on once the throttle get above a certain level, such as 40% throttle. This works very well on Nitro machines and electrics. The only concern on electics is you do not want to flip to a high throttle setting and wait for the ESC to pull it up to RPM. When you flip to a high throttle the Trim lock sees the high throttle and activates. If the machine is not up to flying RPM yet the machine can do strange things. It is best to get up to flying RPM and then go to a higher throttle setting. This will keep the machine from going into Trim Lock before the model is up to RPM and tipping over.
2.) Piro Compensation Pir Comp is the pirouette compensation. The two options are “off” and “Auto”. For either option to get the best pirouettes, you want to go through the procedures below. 1.) Level the swashplate‐ For good pirouettes it is very important to level the swashplate during setup. With collective IPW at 1500 (1530 Futaba) make sure the swashplate is completely level and the blades are at zero degrees. Check that all mixing arms are level and that the blades pitch gauge at zero degrees. It is best to check the pitch first with the blade in line with the Nose of the heli. Then turn 90 degrees and check from the side, then another 90 degrees and check from the tail, then 90 again and check from the other side. So you are checking that the swashplate is level and at zero. With the flybarless the easiest way to pitch gauge it is to add a flat plate to the top of the head block to line up the pitch gauge against. 2.) CG the machine – CG the machine on the main shaft. For electric, balance the machine with the CG on the main shaft ready to fly. With Nitro, balance the machine on the main shaft with half a tank of fuel. Many people either add weight or a larger receiver battery for nose weight. 3.)Mechanically trim the swashplate ‐ turn off the flight control and hover the machine. You want to adjust the rods to the swashplate so the machine hovers stationary in calm air. The idea of turning the flight control off, might make people uncomfortable. But as long as you leveled the swashplate in your initial setup the machine should hover just fine in calm air. The controls might be a little slower than with the flight control on, and the machine might be a little bit out of trim. But it should hover fine and it is not dangerous at all. 4.) Now that the swashplate has been leveled on the bench, the machine CGed and then mechanically trimmed. The machine is good for pirouetting in Auto mode. Just make sure the Pir Comp is set to “Auto” amd fly. Note ‐ If you do not wish to do the above leveling and trimming then leave the Pir Compensation “Off”.
7f.)Flight Tuning – Advanced Settings (advanced tab checked above Flight control setup) 1.) Travel Adjust Aileron – used for additional control travel if you have already set to maximum transmitter travel and mechanical travel and cannot get enough degrees in the blades. Be careful to not bind the controls on the machine by setting these numbers too high Collective ‐ used for additional control travel if you have already set to maximum transmitter travel and mechanical travel and cannot get enough degrees in the blades. Be careful to not bind the controls on the machine by setting these numbers too high Elevator ‐ used for additional control travel if you have already set to maximum transmitter travel and mechanical travel and cannot get enough degrees in the blades. Be careful to not bind the controls on the machine by setting these numbers too high
2.) Stops Left‐ To check the stop, do at least two slow rolls and stop rolling. If the machine bounces when you stop then the number is too low. If it continues to roll when you tell it to stop then the number is too high. Make sure you let go of the control cleanly on the stop. How you let go of the stick can affect the results. Note‐ If you set the stop for a very slight bounce back after the three rolls, the machine tic tocs more consistently. Right ‐ To check the stop, do at least two slow rolls and stop rolling. If the machine bounces when you stop then the number is too low. If it continues to roll when you tell it to stop then the number is too high. Make sure you let go of the control cleanly on the stop. How you let go of the stick can affect the results. Note‐ If you set the stop for a very slight bounce back after the three rolls, the machine tic tocs more consistently. Back ‐ To check the stop, do at least two slow flips and stop flipping. If the machine bounces when you stop then the number is too low. If it continues to roll when you tell it to stop then the number is too high. Make sure you let go of the control cleanly on the stop. How you let go of the stick can affect the results. Note‐ If you set the stop for a very slight bounce back after the three flips, the machine tic tocs more consistently. Forward ‐ To check the stop, do at least two slow flips and stop flipping. If the machine bounces when you stop then the number is too low. If it continues to roll when you tell it to stop then the number is too high. Make
sure you let go of the control cleanly on the stop. How you let go of the stick can affect the results. Note‐ If you set the stop for a very slight bounce back after the three flips, the machine tic tocs more consistently.
3.) Mixes Flip – Adds aileron mix in when giving elevator to make it flip straighter. This is similar to swashplate phasing except it does each control separately. Roll – Adds elevator mix in when giving elevator to make it flip straighter. This is similar to swashplate phasing except it does each control separately.
4.) Misc ‐ Expo This adds expo right at the center of control. This is not like the Expo in the radio. In general you want to leave this at default. Setting this to zero could result in drift issues around center. Higher number makes it more dead at center. For general control feel it is best to use the Expos in the radio instead of this expo.
5.) Reset Parameters This lets you reset all the parameters to their default settings. This is recommended if you got your Total G second hand or if you are confused on the settings and just want to start over. To reset push the Rest parameters button A warning will pop up asking if you are sure you want to reset the parameters. If you do hit yes, you will then see a status bar for reset. Next you will see a pop up telling you to power cycle the total G. Once you power off the Total G and power it back on you will be back at the start page of the interface. The reset is now complete and the parameters should be back to defaults. To go back into the program hit the “connection” button. This will bring you back into the interface so you can go through the setup with a fresh setup.
8.) Background settings (adjust at your own risk)
1.) Speeds: Roll Speed – this will affect the control acceleration from center to about ¾ cyclic stick (aileron). It does not affect the total roll rate at full stick. Setting roll speed higher will allow for faster tic‐toc maneuvers and reversing maneuvers. To adjust the roll rate at full control adjust your transmitter Travel adjust (ATV/ endpoints). If setting your travel adjust above 100 does not give you enough total roll rate then reset your control limits above the recommended +‐ 11 degrees cyclic (aileron). Flip Speed – this will affect the control acceleration from center to about ¾ cyclic stick (elevator). It does not affect the total flip rate at full stick. Setting flip speed higher will allow for faster tic‐toc maneuvers and reversing maneuvers. To adjust the flip rate at full control adjust your transmitter Travel adjust (ATV/ endpoints). If setting your travel adjust above 100 does not give you enough total flip rate then reset your control limits above the recommended +‐ 11 degrees (elevator).
2.) Component Gains: Roll Rate Gain – This affects the rate gain component of the Total roll gain. This is generally a faster response but has less focus on position. Roll Heading Gain – This affects the Heading component of the roll gain. This is a slightly slower component but has its main focus on position. Setting this higher than default can result in oscillations and boomstrikes. Flip Rate Gain‐ This affects the rate gain component of the Total flip gain. This is generally a faster response but has less focus on position. Flip Heading Gain ‐ This affects the heading component of the flip gain. This is a slightly slower component but has its main focus on position. Setting this higher than default can result in oscillations and boomstrikes.
3.) Control Matching: Response Aileron – This parameter is used to match the response of the aileron gyro and the machine. It is more than a stop adjust, but the easiest way to test it is with short quick movements. If you do a small quick tic‐toc and the machine oscillates on the quick stops then this number may be too low. If it coasts then it may be too high. If quick stops are fine, but stops after things like multiple rolls are wrong then adjust the “Stops” instead. Response Elevator – this is the same as response Aileron, just on the elevator axis. The numbers for Aileron and Elevator are usually different.
9.) Interface Programming (Tail Gyro and Governor side) Note: No matter what, you must set the “Low Throttle” and “High Throttle” in the governor, even if you do not plan to use the governor function. The Total G uses the throttle information for other functions.
9a.) Tail Rotor Gyro Setup Regular 1.) Servo Type – Select your servo or one with the same update rates. 2.) Gyro Direction – Check to confirm the tail servo gives the correct control to oppose the movement of the machine. If not, reverse the gyro direction
3.) TR Direction ‐ This teaches the Total G your transmitter control directions. Hold right tail control and confirm the tail rotor does get right control input. If not, reverse the control in the transmitter. Once correct direction is confirmed, hold right tail control and hit “Set”. It should now say Right when you hold right control, Left when you hold left and Neutral when you let go of the control.
4.) Right Limit ‐ When highlighted, the tail control will go to the present right limit setting. To increase this limit, hold full right tail control. To decrease, hold full left. You want the control to go to full limit without binding.
5.) Left Limit ‐ When highlighted, the tail control will go to the present left limit setting. To increase this limit, hold full left tail control. To decrease, hold full right. You want the control to go to full limit without binding.
6.) Gain ‐ Shows the present channel that sets the tail gyro gain and also shows the present gain setting.
Advanced 1.) Rate Mode ‐ Select whether rate mode is active or disabled. When active, one side of the gain channel is Rate mode and the other side is heading mode. When disabled, both sides of the gain channel are heading hold mode.
2.) System Speed ‐ Changes the assumed system speed to match the speed on the model control system. Leave this setting at fast unless instructed to change by manufacturer.
3.) Piro Speed – Adjusts the overall pirouette speed. It is best to first adjust the pirouette speed in the transmitter. Only adjust here if you are not able to get the desired speed with the transmitter travels.
4.) Left CST/RBD – Sets the stops for multiple left pirouettes. To set do three or more left pirouettes and observe the stop. If the left stop bounces then turn this parameter up. If it continues to far before stopping then turn this parameter down.
5.) Right CST/RBD ‐ Sets the stops for multiple right pirouettes. To set do three or more right pirouettes and observe the stop. If the right stop bounces then turn this parameter up. If it continues to far before stopping then turn this parameter down.
6.) Left Stop Speed – Adjusts the speed of the left stop. A higher number gives a harder left stop.
7.) Right Stop Speed – Adjusts the speed of the right stop. A higher number gives a harder right stop. 8.) Left Stop Bounce – In some cases the tail can have a “Double Bounce” on left stops. Turning this number up can help reduce this bounce issue. It only affects the left piro stop, not the right.
9b.) Governor Regular Low Throttle – Put the throttle to low (trim at ¾) and hit “set”. This sets the lowest point the Total G governor can pull the throttle in flight. Make sure to set the correct limits for the carburetor or ESC before setting this parameter.
High Throttle ‐ Put the throttle to full high throttle and hit “Set”. This sets the highest point the Total G governor can push the throttle in flight. Make sure the set the correct limits for the carburetor or ESC before setting this parameter.
Gear Ratio ‐ Set this to the sensor to Rotor blade ratio. So if the sensor is on the motor it is your gear ratio. Note: the numbers are multiplied by ten so 82 = 8.2, 10 = 1.0, etc. . .
Gov RPM ‐ Shows the present channel and RPM setting. Mode – Select the governor mode: Normal, Active or Multi‐Active. Normal ‐ Simply controls the RPM to the set RPM and ignores throttle curves. Active ‐ Uses the throttle curves in the radio and simply adds to the curve in an attempt to keep the RPM constant. It is possible to harm the performance of the governor in Active mode if the throttle curves are too far off. Multi‐Active ‐ Gives you normal mode on one side of the Aux channel and active mode on the other side of the Aux channel.
Advanced Throttle % ‐ Shows the present throttle % as read by the governor. Radio Type – Select whether JR or Futaba mode. In Futaba mode the RPM settings should match the Futaba RPM levels.
Servo Type – For all presently known servos it is best to keep this set to “Standard” servo. Even with Digital servos keep this on standard.
Multiplier – Used to increase the available RPM range for higher RPM applications. The “Gov RPM” in the regular menu will scale with this multiplier.
Enabled – Can be used to turn the governor off, no matter the other settings in the unit. If set to “On” then several other settings can affect whether the governor is working.
Note: No matter what you must set the “Low Throttle” and “High Throttle” in the governor. Even if you do not plan touse the governor function.

Addendum B – G‐view 2 parameter notes Accessing Parameters with the Gview is intended as a way to do quick field adjustments to the Total G. It is not intended that you do major Total G setup through the G‐view 2. Below we give notes showing the location of all the Interface parameters within the G‐view menus. It was not originally intended for the user to access all these items through the G‐view. For this reason many of the names do not match and the order of the items is not particularly convenient. But customers have asked for all the detailed access information, so we are providing it here if you wish to use it.
There are two separate Sections within the G‐view menus. The first section is accessed by hitting “E” first after powering up. This is the section that we recommend the user stay within when adjusting the Total G with the G‐view. The second section of menus is accessed by hitting “+” first after power up. This “+” section is intended as a background menu and the users generally should not need to access this section. The menu list for both of these sections is below: Flight Control “E” Menus General Settings Aux Channel Assignments Input Pulse Width Servo Setup CCPM Control & Gyro Setup Flight Tuning E Exit Menu P Continue (scroll to here and hit E to exit menu) “+” Menus Servo Neutrals Servo Travels ccpm Parameters Flite Control Input Pulse Width Roll Axis Stops Roll Gyro Gains Flip Axis Stops Flip Gyro Gains Spek1 Miss Throttle Aux Chan E Exit Menu P Continue (scroll to here and hit E to exit menu) Once you are in either menu, you push the up or down arrows to scroll through the menus. Then push “E” to enter a specific menu. To exit that menu, push “E” again. To exit the overall section, scroll to the end of the section “E Exit Menu P continue” and push “E” to exit. Following are sections of the interface with their matching G‐view location to the right. The location is shown as below: Menu location>parameter The “>” represents entering or leaving the menu item by hitting E. If a “+>” starts the location listing, this indicates it is in the “+” menus. If it has no label before the menu it is in the “E” menus.
Addendum C – Tail Side addition notes
Reset tail parameters ‐ in the G‐view section go to TR Gyro Setup>Function Menu> ResetParam. Hit “+” to turn “Reset Param” to “On” and then power cycle the Total G. The tail side of the total G will now be reset to all default parameters.
Reduce whipping in high speed pirouettes ‐ go to TR Gyro Setup>Response Menu> Pir Gain. Try turning up Pir Gain from default to 25 or higher. If it is set too high you will see oscillation during pirouettes.
Recalibrate tail Gyro if drifting on the bench ‐ This is not in the main menus because most people should not need to re‐calibrate their tail gyros. To avoid people actually messing up their unit we have kept this explanation to the addendum and only accessed through the G‐view. There are three parameters that you need to compare to recalibrate the tail gyro. Their locations are listed below. TR Gyro Setup>Extras>ADC Value TR Gyro Setup>Extras>HGyrTmCmp TR Gyro Setup>Extras>Gyrocenter The ADC value is the actual value of the sensor at that moment . If the unit is sitting still it might be around 500 (does not have to be that, just likely near that). The HGyrTmCmp is the present compensation the unit is using to prevent drift (this number can vary a lot and can be positive or negative). The Gyrocenter what the Total G looks for from the Gyro sensor to indicate the sensor is still. This value is a factor of 10 higher than the actual signal number, just move the decimal place over one to compare them. The goal is for the “ADC Value” to be about the same as the “Gyrocenter Value/10” when the unit is sitting still. If they are not close then you adjust the “HGyrTmCmp” up or down to make them the same. Adjusting HGyrTmCmp is what helps to match Gyrocenter and ADC Value. This resets the factory temperature compensation. We do not recommend doing this unless you first confirm you have no rudder pot issues in your transmitter. If you compare the “ADC Value” and “Gyrocenter/10” it should tell you if there is a sensor related drift problem. If the ADC Value and the Gyrocenter/10 are off by more than 1 full unit then you might see some drift from the sensor. An example ADC Value 508 and Gyrocenter 5076 should be fine ADC Value 508 and Gyrocenter 5068 or 5092 will like have some drift but small. Larger variation would cause more drift. And if the drift is not causing you any issues in flight I would not worry about it. Only change these numbers if you have a drift issue that is bothering you in flight and these numbers are far enough off to cause the drift.
