- A remote control with 6 or more channels (collective, roll, nick, yaw, throttle,flightmode)
- A good ESC with governor mode (keeps the head RPM constant)
- A flybarless helicopter (flybar heads are currently not supported)
Reset all Mixer/Expo/Dual rate/Trim settings. If your remote control allows you to set the number of swashplate servos, be sure to choose one servo (Graupner remote controltransmitter need to set this, the Taranis is already pre setup in the right way). All the servo mixing is done by the FC (your flight controller), not by your transmitter. Consult If unsure consult the documentation of your transmitter. This documentation describes the setup of a Trex 450. Check the FC firmware and update if needed.
Also check your helicopter for:
- vibration free minimized setup
- correct linkages lenght and angles
- smooth moving pushrods
- secured screws
- correct adjusted belt tension (if applicable)
- vibration damped, safe attached FCFC
- unsecured cables
Safety warning:
...
Set the the correct swashplate type (for this helicopter we use 3 servos and 120 degree angle) and define the output channels. Define the position of the first servo (rear one). The setup shall match the the output cabling according to the output cabling table

Swashplate leveling:
Here you can adjust swashplate. Before you begin center your servos and mount the servo horns as near to the neutral position as possible. It cant be done perfectl perfectly at the first step but it will be fine tuned during the swashplate level procedure. To avoid mechanical collisions between the frame and the chassis. remove the pushrods from the servosservo horns. On the output screen set all servos to neutral=1500 μs 1500μs minimum to =1200μs and maximum to =1800μs. Thats a reduced servo movement range but at the moment fine as start values. It shall look like this:
...
After verifying that all servos are moving correct reconnect the linkages to the servo horns and restart the wizard. The neutral position of the servos horns is already set, so adjust the linkages to level the swashplate. Verify also the maximum minumum position (+-15°) and minimum maximum position (-15°+20°). Keep in mind that collective and cyclic will mixed (added) together by a 50% multiplier on each component. So the pre setup swashplate travel of -15° to 15° to -20° will result in a effective travel of -7.5° to +7.5° 10° travel plus the cyclic component. Dont forget to level the swashplate at the maximum and minimum position. Use only the slider to change the values, if you enter the position directly and with values out of the servo move range you can easy destroy your swashplate servos. After setting up the swashplate your output screen may look litke this:
