Here are some controller calibration and function settings.

  • SAVE (after modified controller configuration must click save to take effect)

  • Calibrated (calibration state, If the indicator is red, calibration for roller hardware, rocker hardware and SBUS output is necessary. If the indicator is green, it is normal and no calibration is required)




  • AXIS


  • REV

  • DZ

  • EXPO

  • CH#

  • Wheel Acc

  • Throt Cent 0

  • Mode

  • Dual Cont

  • MAIN

  • IP

First time use requires three calibration steps:

1. Calibrate the Hardware Wheel

  • Select “HW WHEEL CAL

  • Click "Start Rollwheel" & follow the calibration steps. Note: Once complete you can check it's functioning correctly by looking at the value changes.

  • Move the wheel all the way left and right a few times.

  • Click “Pass” to return to the joystick screen.

After the Rollwheel calibration is complete, proceed to the next step.

2. Calibrate the Joysticks

Click "HW JS CAL"

Click "Start Calibration" to begin the process and follow the instructions in the green box, and the stick movement arrows located around the sticks on the remote as highlighted in RED below.

Note: At the beginning of the calibration process, the stroke of the joystick on the screen will not change with the physical joystick movements. You need to calibrate according to the instructions.

At the end of this process if you are happy with the input behavior you can click "Pass" and the calibration will be stored, if you're experiencing any issues click "Fail" and start the calibration process again using a little more pressure in the corners.

After the Joy-Stick calibration is complete, proceed to the next step.

3. Calibrate SBUS Output

Follow the RC stick movement steps as shown in the highlight section moving the sticks through each position. Finally, move the wheel, then the calibration is done!

Once all calibrations have been completed the **Calibrated ** status will turn GREEN which indicates that all remote calibrations have been completed.
