Programming the FlySky FS-i6 Transmitter for Combat Robotics
Privacy Policy
You bought a FlySky-i6 radio system because of its impressive list of features, its incredibly low price, and its popularity with combat robot builders. It's what you call a 'no-brainer'. Then the box arrived and it contained a transmitter, a receiver, and no manual. A quick search on the 'net and you have the FlySky manual -- half of it is in Chinese and the other half might as well be. No problem, you head over to YouTube and soon have multiple videos on how to setup the FS-i6... for airplanes, helicopters, and quads. What about your combat robot?

Not to worry -- I'm here to help. I'll try to avoid aircraft related names when describing the radio functions but I'll leave them in where required to allow reference to the manual or labels on the transmitter.

There are multiple versions of the FS-i6 manual on-line. None are good, but the best is this all-English version via the FlySky site.

7xmovies 300mb top
The FlySky i6X transmitter is functionally very similar to the FS-i6. There are some internal differences but almost everything in this guide applies to the i6X as well. I've added an FS-i6X Note in places where I have found differences.

The contents of this guide were tested and verified on a FlySky i6 running firmware version 2.0 dated 16-Aug-2017.


Quick and Dirty FS-i6 Combat Set-up
You're in a hurry? You don't want any details? You just want to slap a quick setup on the transmitter and run? Grab four 'AA' cells and stuff them in the transmitter. Here we go...
Step 1: Turn On Elevon Mixing

Flip all the toggle switches along the top of the transmitter 'up' and pull the left control stick all the way 'down'. Push the power switch 'up'.

  • Press and hold the 'OK' key 'til the 'MENU' screen appears.
  • Tap the 'Down' key to highlight 'Functions setup' -- tap 'OK' to select.
  • Use the 'Down' key to scroll down the list to 'Elevon' -- tap 'OK' to select.
  • Tap the 'Down' key to turn Elevon 'On'.
  • Use the 'OK' key to scroll to 'CH2', then the 'Up' key to set it to 100%. Leave 'CH1' at 50%.
  • Press and hold 'Cancel' to exit and save the Elevon settings.
  • Tap 'Cancel' to return to the 'MENU' screen.
Yes, I know holding 'Cancel' to save makes no sense. Chinese radios...
Step 2: Set Correct Failsafe

Back at the 'MENU' screen:

  • Tap the 'Down' key to highlight 'System setup' -- tap 'OK' to select.
  • Use the 'Down' key to scroll down the list to 'RX Setup' -- tap 'OK' to select.
  • Use the 'Down' key to scroll down the list to 'Failsafe' -- tap 'OK' to select.
  • Pull the left stick all the way down, and leave the other stick axis spring centered.
  • Tap 'OK' to select channel 1, tap 'Down' to turn failsafe 'On', then 'OK' to return to channel selection. Tap 'Down' to the next channel and repeat for channels 2, 3 and 4.
  • With all channels correctly set, press and hold 'Cancel' to exit and save the failsafe settings.
  • Tap 'Cancel' three times to step back to the status display screen.
Note: non-FlySky receivers may require other methods to set failsafes. Consult their manuals for info.
There you are. Throttle and rotation are on the right stick, left and right motor controllers plug into receiver ports 1 and 2, and the stick channels all failsafe to 'off'.
  • Test the throttle and rotation response of your drivetrain. If the response isn't correct, step thru the 'Troubleshooting Channel Mixing Problems' checklist.
  • If using channels 5 and 6: see the 'Aux Channels' function to assign an appropriate switch or knob to each channel. Set the switches/knobs to 'zero motion' positions and go back to 'Step 2' above to add failsafes to those channels.
Turning On the Transmitter
You'd think this part would be easy. Down in the lower right corner on the front of the transmitter there's a shiny chrome slide switch with an up arrow icon labeled 'Power'. It's really tempting to slide that switch upward. If you do, you're likely to set off a storm of alarms and cryptic alert messages. As a safety measure the transmitter sticks and switches must be in 'safe' positions when the power is turned on to prevent unexpected and possibly dangerous responses from your 'bot. Here's the drill:
  1. Flip the four toggle switches (SWA, SWB, SWC, SWD) along the top of the transmitter 'up';
  2. Pull the non-spring centered control stick (channel 3 'throttle') all the way 'down';
  3. Now you can slide the 'Power' switch 'up'.
If you try to turn it on and get a warning, you can correct the sticks and switches and it will power up; you don't need to slide the switch back off and start over.
Warning
The transmitter does not check the positions of variable knobs VrA and VrB before powering up. Channels 5 and 6 are assigned to those knobs by default -- do not assign weapons or direct motion control to the FS-i6 variable knobs!

Menu Navigation
Menu navigation does not follow an entirely consistent method, but it starts to make a certain amount of sense after you get used to it.
  • At startup the transmitter display screen shows info about the currently selected 'model' (model number, name, aircraft type, transmitter protocol) and the general state of the transmitter (battery voltage, charge, trim tabs).
  • Access the programming menus by pressing and holding the 'OK' button. Highlight either the 'System Setup' or 'Functions Setup' with the 'Up/Down' keys and tap 'OK' to enter the selected menu. Each tap on the 'Cancel' button will back you up one level thru the menu without saving any changes.
  • The navigation process changes when you get to a menu screen with changeable items. On these screens the 'OK' button will scroll downward thru the items and the 'Up/Down' buttons change the value of the current item.
  • If the screen backlight goes off, press any key to turn it back on. The menus will not accept any inputs until the light is back on.
  • A press and hold on 'Cancel' will save the changes (audible beep) and exit to the parent menu, while a quick tap on 'Cancel' will exit without saving changes.
  • Yes that's right; you hold down 'Cancel' to save your changes. You have to live with some strangeness if you buy a cheap Chinese radio.

Modes, Mixes, and Control Sticks
You have a lot of choice when it comes to how the controls for your robot are mapped to the various sticks, switches, and knobs on the transmitter, but you need to know a little about the actual purpose for which the transmitter was built. Twin-stick transmitters like the FS-i6 are made to control airplanes, helicopters, and drones. If you learn a bit about aircraft terminology the manual will make much more sense.
The four axes of the dual control sticks are assigned to channels 1 thru 4 on your transmitter. These four channels are traditionally assigned names related to the elements they control on model airplanes:
7xmovies 300mb top
Ch 1: Aileron (Roll)

Ch 2: Elevator (Pitch)

Ch 3: Throttle (Thrust)

Ch 4: Rudder (Yaw)

Combat robots don't require pitch or roll controls, and the 'thrust' control on an airplane-style, forward-only, non-centering control stick does not meet our need for forward/reverse drive motor control. We apply these control functions very differently, but since we 'borrow' these radios from aircraft hobbyists we need to know enough aircraft terminology to translate the radio manuals for our needs.



Transmitter Modes [][][]
There are two 'standard' ways to assign input channels to the two control sticks:
Transmitter Mode 1 is the European standard with Throttle channel 3 on the vertical axis of the right stick, and Elevator channel 2 on the vertical axis of the left stick.
Transmitter Mode 2 is the U.S. standard which has the vertical sticks reversed: Throttle channel 3 on the left stick and Elevator channel 2 on the right stick. The FS-i6 transmitter comes with Mode 2 enabled.
7xmovies 300mb top


The FlySky FS-i6 allows switching between these two 'standard' modes and offers two additional modes, but neither Mode 3 nor Mode 4 have any benefit in robot combat. See Stick Modes in the 'System Settings' section.



Standard Mixes [][][]

It is convenient to set-up a combat robot transmitter with one stick axis commanding both drive motors to move forward/reverse, and another stick axis commanding the motors to move in opposite directions to turn by 'rotation' of the robot. We are fortunate that airplane transmitters typically have that capability due to some unusual airplane wing and tail designs that require two servos to move together to control the Elevator function and to move opposite each other to control the Aileron or Rudder function.
Elevon mixing aka Delta Wing - places the robot throttle control on Elevator channel 2 and robot rotation on Aileron channel 1.
V-Tail mixing also places the robot throttle on Elevator channel 2, but moves robot rotation control to Rudder channel 4.
By selecting the correct combination of transmitter mode and channel mixing type we have the option of independently placing the throttle and rotation command axes on the left or right sticks to suit our preference.



Stick Assignments [][][]

Here is the basic setup matrix for mixes, modes, and receiver outputs to put the controls on the sticks you want to use. Pick the control positions you want from the left columns, then implement the associated mix and mode.
Throttle
Stick		 Rotation
Stick		 Mix Type Mode Ports
RightRightElevon22 - 1
LeftRightElevon12 - 1
RightLeftV-Tail22 - 4
LeftLeftV-Tail12 - 4

Most builders set up in Mode 2 with Elevon mixing: throttle and rotation on the right stick.

My own preference is Mode 1 with Elevon mixing: throttle on the left, rotation on the right.



Stick Centering [][][]

Picking a Mode 1 stick assignment from the above table will place robot throttle control on the vertical axis of the left stick, which is not spring-centered. You have some options to correct this problem:
  • It's a simple task to switch the positions of the two stick gimbals, moving the non-centering stick to the right side. Video.
  • If you'd rather have both sticks spring-center you can purchase a complete replacement stick assembly for about $10 -- shipping included. There are two styles: select the 'Direction' model that self-centers both axes, not the 'Throttle' model. Replacement is simple: video.
After replacement you can start the transmitter in the same way as usual and just flick the left stick down to cancel the alarm. You can set the 'Throttle Hold' switch to inactivate the channel 3 response on startup if flicking the left stick down would cause trouble -- see the 'Throttle Hold' section of this guide.

FS-i6X Note The FS-i6X Secret Menu has a "Self Centering" function that when set to "On" allows startup with the throttle stick centered. Very handy.


Functions Menu Programming
The FlySky FS-i6 and other twin-stick radios are designed to control a variety of fixed-wing and rotor-wing aircraft. Many of the control functions available on the transmitter are of no use to combat robot applications. The functions in this section have specific combat robot applications. They are listed in (almost) the order they occur in the menu -- I moved a couple to the end for special attention.
To enter the 'Functions Menu': hold down 'OK' to open the 'MENU' screen, tap the 'Down' key to highlight 'Functions Setup', and tap 'OK'. Scroll thru the menu items with the 'Up/Down' keys, then tap 'OK' to select.


Reverse [][] Port Level
When you push the throttle forward does your robot back up or spin in a circle? This function allows the response of each receiver output channel to be reversed. If you spin in a circle, reverse the channel for the motor output that is spinning backward -- if you back-up, reverse both motor output channels.
  1. Tap the 'OK' key until the desired channel is selected, then use the 'Up/Down' keys to change setting: Nor = Normal, Rev = Reverse.
  2. Press and hold the 'CANCEL' key to save and return to the previous menu, or tap the “Cancel” key to exit without saving the changes.


End Points [][] Port Level
Known on some other transmitters as 'Adjustable Travel Volume' (ATV) or 'Travel Adjust', this function sets the range of response of a device plugged into a specific receiver output. Full transmitter stick/switch/knob input can be set to produce anywhere between 0% and 120% of normal response at the specified receiver port.

Response is set independently for each side of the center 'neutral' position -- move the stick/switch/knob for the channel you're setting to the side you wish to set.

For many combat robot purposes it is more convenient to use the ‘Dual Rate’ function for this purpose, but control functions operating on channels 3, 5, or 6 may find ‘End Points’ useful.

  1. Tap the 'OK' key until the desired channel is selected.
  2. Move the stick/switch/knob for the selected channel to switch between setting the high or low end of travel.
  3. Use the 'Up/Down' keys to increase/decrease the setting.
  4. Press and hold the 'CANCEL' key to save and return to the previous menu, or tap the 'Cancel' key to exit without saving the changes.


Display [][][]
Why is this in the 'Functions' menu? 'Display' is a diagnostic tool that doesn't fit into a menu assigning control functions. There are other diagnostics in the secret and well-hidden Factory Menu -- maybe it should be there?

'Display' pops up a graphic representation of the real-time output of signals being sent out to the receiver. It's a very handy tool that saves a lot of time when sorting out transmitter function programming problems -- but it's also potentially dangerous.

Holding down 'OK' in 'Display' starts 'Channel Scrub Mode' which sweeps all channels back and forth thru their full range. This continues until you tap 'Cancel'. You don't want your 'bot to run erratically around your workshop cycling its weapon on and off, so: Keep the 'Bot Power Off!

7xmovies 300mb top

Move each stick/switch/knob to verify the effects of Channel Reversing, End Points, Auxiliary Channel Positions, Dual Rates, Switch Assignments, and Mixes.


Aux Channels [][][]
The two control sticks use channels 1 thru 4 on the transmitter, but this is a six-channel transmitter. What about those other two channels? The Auxiliary Channels function can assign radio channels 5 and 6 to any of the four switches (SWA, SWB, SWC, SWD) or two variable knobs (VrA, VrB). Most versions of the FS-i6 transmitter firmware default to assigning radio channels 5 and 6 to variable knobs VrA and VrB.
  • Switches SWA, SWB, and SWD are simple two-position toggles. A radio channel assigned to one of these switches the device controlled by that channel will have two possible command states. In model airplanes channel 5 is often assigned to a two-position toggle for the up/down actuation of retractable landing gear, aka Retracts. In a robot you might use a two-way toggle channel to turn on a hardware 'invert' function, or to turn a piezo gyro on/off.
  • Switch SWC is a three-position toggle. An ESC with reverse on a channel assigned to SWC can provide 'forward/off/reverse' control of a motor. A forward-only ESC on SWC can provide 'fast/slow/off' motor control. If a servo is on the channel you will have left/center/right control.
  • Variable knobs VrA and VrB provide continuous range control to a channel assigned to them, like a stick axis. In model airplanes channel 6 is often assigned to the control of Flaps which modify the lift properties of the wing at slow flight speeds. See the warning about assigning robot weapon control to the FS-i6 knobs in the Turning On the Transmitter section of this guide.
  1. Tap the 'OK' to change between channels 5 and 6.
  2. Use the 'Up/Down' keys to select a specific switch or knob. Select 'None' to deactivate all controls for that channel.
  3. Press and hold the 'CANCEL' key to save and return to the previous menu.
FS-i6X Note The FS-i6X has an extra function in its 'System Menu' called 'Aux Switches' that can activate and deactivate individual switches and knobs. If you have a FS-i6X and you do not see all of the switches and knobs that should be available to you in the 'Aux Channels' functions, check the 'Aux Switches' function to make sure they are all activated.



Subtrim [][] Port Level

The mechanical trim settings by the sticks on the transmitter adjust the center position of that stick axis. If multiple output channels are ‘mixed’ on that stick axis they will all be affected. ‘Subtrim’ lets us adjust the center positions of individual receiver outputs. Two motor controllers mixed to a single transmitter stick can be individually adjusted so that both motors power up together at slow speed rather than one motor turning on first resulting in a very slow turn instead of a slow forward crawl.

To set subtrims: prop the drive wheels off the ground and push the throttle forward slowly 'til one motor just starts to turn. Select the receiver channel the other motor is plugged into and slowly increase the 'Subtrim' setting 'til both motors turn.

  1. Tap the 'OK' key until the desired channel is selected.
  2. Use the 'Up/Down' keys to change the subtrim position.
  3. Holding the 'OK' key down for 2 seconds will zero all subtrims.
  4. Press and hold the 'CANCEL' key to save and return to the previous menu, or tap the 'CANCEL' key to exit without saving the changes.


Dual Rate/Exp [][][]
'Dual Rate' and 'Exponential Response' are typically addressed separately in transmitter function settings, but FlySky has opted to combine them into a single setting. Both functions are switched between their two settings at the same time by switch SWA (top left on transmittter).

These functions can only be applied to stick channels 1, 2, and 4 -- but channel 3 has its own switchable functions: see 'Throttle Curve' and 'Throttle Hold' at the end of this functions setup section.

Dual Rate offers a switchable reduction or increase in the influence that movement of a specific transmitter stick has on receiver output, effectively limiting the response of the stick.

For a combat robot a dual rate is commonly used to adjust 'Rotation' sensitivity. A robot with a full-range response on the 'Rotation' channel can be difficult to control in the ‘heat of battle’ – over correcting and zigzaging across the arena. Setting a dual rate on the 'Rotation' channel can keep your ‘bot composed under normal conditions and still allow a full-rate 'righting spin' or 'victory dance' at the flip of a switch.

Exponential Response effects fine-level control, but in a different way than dual rate. Entering negative values here will reduce the sensitivity of the control stick near the center of stick motion to allow for fine control, but increase sensitivity as stick motion approaches the limit of travel to ‘squeeze in’ full response range. I leave 'Exp' at zero, but feel free to experiment.

  1. Flip switch 'SWA' (top left on transmitter) 'up' to set 'normal' response settings. Leave 'sport' response settings (SWA 'down') at defaults.
  2. If needed, tap the 'Up/Down' keys to select the desired channel: Ch1 for an Elevon mix.
  3. Tap the 'OK' key to select 'Rate' and use the up/down keys to set the value to '50'.
  4. Tap the 'OK' key to select 'Exp' and use the up/down keys to set the value. I leave this at zero.
  5. Press and hold the 'CANCEL' key to save and return to the previous menu.

 Mix  [][][]
In R/C aircraft it's common for a change in one control to have an undesired effect on stability that must be countered by a second control. For example, actuating Flaps may require a change in Elevator to keep the plane level. The 'Mix' function allows you to program a custom response in a 'slave' channel whenever the 'master' channel actuates to offset these undesired effects. You may have up to three of these custom mixes.

  • The preset 'Elevon' and 'V Tail' mixes (below) are all you need to setup single-stick control of your differential drive motors. The custom mixes can be saved for other uses.
  • The FS-i6 does not allow custom mixes to be assigned to a transmitter switch to turn them on/off in combat; they must be turned on/off from within the menu system. This severely limits their use in combat robot control. For example, they cannot be used to create a 'invert switch' that corrects the reversal of the forward/reverse stick axis when the robot is flipped upside-down.



Elevon [][][]

'Elevon' is the standard channel mix for single-stick combat robot control. In the default 'Transmitter Mode 2', Elevon mixing places both throttle and rotation control on the right-hand stick, leaving the left stick open for other uses.

Vertical stick axis #2 Elevator commands both speed controllers in the same direction for forward/reverse motion, while horizontal stick axis #1 Aileron commands the speed controllers in opposite directions for left/right rotation. Left and right side speed controllers plug into receiver ports 1 and 2.

  • Change both ‘percentage’ settings to 100%; that will be too much rotation authority for stick #1, but we will correct that with a ‘Dual Rate’. If not using a dual rate, leave channel 1 at the default 50% and set channel 2 at 100%.
  1. Use the 'Up/Down' keys to turn the function on/off.
  2. Tap the 'OK' key to move down thru the percentage settings.
  3. The 'Up/Down' keys change the selected percentage setting.
  4. Press and hold the 'CANCEL' key to save and return to the previous menu, or tap the 'Cancel' key to exit without saving the changes.


V-Tail [][][]
V-tail is used less frequently than Elevon as a combat robot drive mix. It moves the rotation control axis from the generally preferred right stick Aileron location to the left stick Rudder location. Right and left side speed controllers plug into receiver ports 4 and 2. Setup is the same as the Elevon mix.



Switches Assign [][][]

The 'Switches Assign' function controls which switches control 'Fly Mode', 'Idle Mode', and 'Throttle Hold' selection.
  • Fly Mode Switch On many radios this is called the 'Dual Rate Switch' because it controls which 'Dual Rate' is active. Switch SWA is the default assignment.
  • Idle Mode Switch A flip of this switch selects which of the two throttle response profiles available in the Throttle Curve function is active. The effect is similar to the 'Dual Rate/Exp' function available on other stick channels. Switch SWB is the default assignment.
  • Throttle Hold Switch If the 'Throttle Hold' function (see below) is activated, a flip of this switch will cause the transmitter to ignore the position of the channel 3 stick axis and set the channel 3 output to a specified percentage. Switch SWD is the default assignment.
  1. Tap the 'OK' key to step between the three assignable controls.
  2. Use the 'Up/Down' keys to change the switch assignment.
  3. Press and hold the 'CANCEL' key to save and return to the previous menu, or tap the 'CANCEL' key to exit without saving the changes.

I moved the 'Throttle Curve' and 'Throttle Hold' functions out of menu-order and put them here at the end of the section because it makes sense to discuss them after the 'Switches Assign' function.

Throttle Curve [][][]
This function adjusts the response of channel 3 to compensate for non-linear engine responses in 'gas' engines. It is similar to the 'Dual Rate/Exp' function for the other stick channels but a more elaborate response curve can be defined by setting response at five stick points: 0%, 25%, 50%, 75%, and 100%.

It has two modes controlled by SWB: 'Normal' and 'Idle Up' that are set independently -- like the dual rate. I can't think of any use for this function on a combat robot unless you're running an internal combustion engine on your weapon.

  1. Flip the 'Idle Mode' switch (default SWB) up to enter the 'Normal' response curve.
  2. Tap 'OK' to select the curve point to change.
  3. Use the 'Up/Down' keys to change the point position.
  4. Press and hold the 'OK' key to return all points to default settings.
  5. When finished setting 'normal' response, flip 'SWB' down to set the 'Idle Up' curve points.
  6. Press and hold the 'CANCEL' key to save and return to the previous menu, or tap the 'Cancel' key to exit without saving the changes.


Throttle Hold [][][]
This function will lock channel 3 to a fixed percentage output and ignore the position of the stick. In a combat robot this is commonly used as a safety 'lock out' for a spinner weapon. It works like this:
  • The 'power on' safety system will not allow the transmitter to become active unless all four toggle switches are in the 'up' position and the channel 3 stick is all the way down.
  • Once the transmitter has power, the channel 3 stick is held inactive by the 'Throttle Hold' switch SWD being in the 'Not Engaged' up position.
  • The channel 3 stick will remain inactive until SWD is switched down to release the throttle hold.
  1. Flip the 'Throttle Hold' switch up to enter 'Not Engaged' mode.
  2. Tap 'Up/Down' to turn 'Hold' on.
  3. Tap 'OK' to select the 'Value' setting.
  4. Hold 'Down' to set 'Value' to 0%.
  5. Flip the 'Throttle Hold' switch down to verify that 'Hold' is off in the 'Engaged' setting.
  6. Press and hold the 'CANCEL' key to save and return to the previous menu.

System Settings Menu
Some minor functions important to combat robot control preference are hidden away in the 'System Settings' menu even though they apply to the specific robot being controlled rather than the transmitter system itself.
To enter the 'System Settings Menu': hold down 'OK' to open the 'MENU' screen, tap 'Up/Down' to highlight 'System Setup', and tap 'OK'. Scroll thru the menu items with the 'Up/Down' keys, then tap 'OK' to select.


Model Setup Functions [][][]
This group of functions allows you to save up to 20 sets of function/system settings and quickly switch between them to control different robots. If you have only one robot you can ignore this section. The manual is accurate and complete for these functions, and the commands are intuitive -- I won't duplicate the instructions. Here's an overview:
Model Name

Now that you have the transmitter functions set up for your first robot, this function will assign a name to that set of functions so you can spot recognize it in the list of saved function sets.

Type Select

The FS-i6 is made to control airplanes and a variety of helicopter styles. The helicopter types are very specific to helicopter functions and are of no use to combat robots. Stick with the default 'Airplane or Glider' type.

Model Select

When you're ready to start setting functions for a new robot you will need to select an unused model to avoid overwriting the functions you set for the prior robot. When you want to use a saved model, this is where you find it.

Model Copy

Is the new set of functions you're going to set-up similar to an existing model you already have? Save some time and 'Copy' that existing model into the new unused model you just selected and save a lot of time.

Model Reset

Do you have a saved model you no longer need? This function will reset all the functions and clear the name. You will be prompted to confirm the reset.



Sticks Mode [][][]
The function maps transmitter channels 1 thru 4 to the control stick axes. See the section on 'Transmitter Modes, Mixes, and Control Sticks' for factors to consider in selecting stick axis locations.


Receiver Setup Submenu
Hidden down near the bottom of the 'System Settings Menu' is a 'RX Setup' option that opens a new submenu. Most of the functions included in this sub-menu apply only if you're adding receivers that use a different protocol or setting up telemetry sensors. There is only one programming function hidden in here, but it's an important one. The 'Failsafe' function determines how your robot will respond when the transmitter signal is lost.



Failsafe [][] Port Level

The default failsafe 'Off' setting will lock the selected channel on any of the 'A series' receivers (A6, iA6, iA6b...) in the last setting it had before the transmitter signal was lost. That is not an acceptable response for a combat robot!

Turning failsafe 'On' will return a receiver port to a pre-selected safe setting that will bring all motion on the robot to a stop -- a correct failsafe response.

Not using one of the 'A-series' receivers? Check your receiver docs for their failsafe info.

  • Use the 'Up/Down' keys to navigate to the 'System setup' screen -- tap 'OK' to select.
  • In the 'System Setup' menu, 'Up/Down' to scroll to 'Receiver Setup' -- tap 'OK' to select.
  • 'Up/Down' to scroll down the list to 'Failsafe' -- tap 'OK' to select
  • Pull the left stick all the way down, and leave the other stick axis spring centered.
  • Tap 'OK' to select channel 1, 'Up/Down' to turn failsafe 'On', then 'OK' to return to channel selection. 'Up/Down' to the next channel and repeat.
  • When you get to channels 5 and 6, adjust the two variable knobs (VrA, VrB) to positions appropriate for failsafe before turning failsafe on and tapping 'OK'. That's typically 0% for a forward/reverse ESC, -100% for an R/C switch or a unidirectional ESC.
  • When all channels are correctly set, press and hold 'Cancel' to exit and save the Elevon settings.
  • Tap 'Cancel' three times to step back to the status display screen.


Troubleshooting Mixing Problems
Having your channel mixing setup correctly on your transmitter gets the right signals sent to your receiver, but that doesn't mean that your robot is going to respond correctly to the stick inputs. The left and right side motor controllers may be plugged into the wrong receiver ports, the current polarity to the motors may be reversed, and you may even have accidentally activated a mixing option in the controller board that is competing with your transmitter mixing.
7xmovies 300mb top The easy solution is to try my interactive on-line Robot Mixer Fixer. Answer three questions and get a quick and complete solution to your mixing problems.

Off-line? Step thru the list of symptoms below and correct each problem you as you find it. There is some trial-and-error with this manual process, but it will eventually get you up and running.

Given a forward command, only one motor responds -- given a right turn command, only the other motor responds.You have either all mixing turned off, or both transmitter mixing and speed controller mixing turned on. Adjust so one and only one mix source is active. Given forward command, robot backs up straight.Use the transmitter Reverse function on both of the channels that feed your motor controllers. Given forward command, robot spins in place.Use the transmitter Reverse function on the channel that feeds the controller for the motor that is backing up. Given right turn command, robot turns left, and vice versa.Swap the receiver plugs for the two channels that control the motor controller(s). If you are using channels 1 and 2, unplug the receiver connectors and plug the connector that was in channel 1 into channel 2 and vice versa. You may have to correct the servo reversing for the two channels after doing this to get correct forward/reverse motion, but the turning control will be correct when you're done.
