RC Input Channel Mapping (RCMAP)

This article shows how to set up a non-standard RC input channel mapping using the RCMAP feature.


By default the RC input channels are:

  • Channel 1: Roll input

  • Channel 2: Pitch input

  • Channel 3: Throttle input

  • Channel 4: Yaw input

These can be changed by setting the RCMAP_ROLL, RCMAP_PITCH, RCMAP_THROTTLE and RCMAP_YAW parameters using the Mission Planner’s Config/Tuning | Full Parameter Tree (or Full Parameter List) as shown below.


After changing any of these parameters the autopilot should be rebooted.

Additional information about the RCMAP parameters can be found for the respective platforms in: Copter Parameters, Plane Parameters and Rover Parameters.

Rover notes

As a real example, if your aileron (steering) is on channel 1 and your elevator (throttle) is on channel 2, then the settings should be:



RCMAP_PITCH and RCMAP_YAW can be whatever channels you want to make them as long as they are not channels 1 and 2.

For Rover you should also select the receiver channel that will be used to control the Mode select (MODE_CH).
