I have an independent servo controlling my nose wheel and have it assigned to ground steering. I would like to control ground steering with a knob on my transmitter instead of the yaw stick. Can I do that? I don’t want to lose the ground tracking ability though.
You can map whatever channel you like for Ground Steer. For example, I use the Roll stick which is on Channel 1 for Ground Steering. But, I could assign a Pot on the Tx to say Channel 12 and set RCMAP_ROLL from 1 to 12.
Ha, I just realized this is Plane and not Rover. I should pay more attention!
Thanks for the reply. Unfortunately, that would also map my rudder to the pot. I am trying to decouple steering input from yaw input.
What type of transmitter are you using? A transmitter running EdgeTX will allow any input on the radio to map to any channel.
Just to clarify, why have you activated ground steering if you want to control the rudder and the steering wheel servo independently of each other using the pot and the rudder stick?

My use case is while in FBWA mode, I would like to control ground steering of my plane during taxi with a pot. During the takeoff roll, I would like Arduplane to maintain the compass heading from my GPS/Compass in order to stay straight on the runway. Once in flight, I would like yaw demand to come from the throttle/yaw stick. I am using an FrSky transmitter running Ethos. It’s not a showstopper to steer with the rudder stick, I just wanted to see if I could control them separately to test some different ground steering scenarios.
The docs infer that, no, you cannot map a PWM input channel to the servo assigned to the ground steering function. I think for my purposes of creating a “tiller steering” feature, the best solution is to create a transmitter mix that adds the pot input to my rudder channel and disables it above a specific throttle value. My goal is to better understand and be able to tune the steer2srv parameters while the plane is on the ground. So, whether or not the rudder moves while I steer is not an issue.
you could add a switch enabled mixer to Rudder that will add the pot to the rudder output.
