RC Input Channel Mapping (RCMAP)¶
This article shows how to set up a non-standard RC input channel mapping using the RCMAP feature.
This feature is available in AC3.2.1 and higher (and equivalent Plane and Rover versions).
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 flight controller should be rebooted.
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_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 channels that will be used
to control the Waypoint select (LEARN_CH)
and the Mode select (MODE_CH).
As an example, the Gear switch (2-way) is on channel 5 and can be
assigned to the
LEARN_CH while the Flap switch (3-way) is on channel
6 and can be assigned to the
