I am trying to use an APM 2.6 on a Powerwheels jeep with a linear actuator to control the steering. I am trying to go through the calibration wizard in Mission Planner with the APM disconnected from the Powerwheels jeep. Not doubt you can understand rotating through 6 degrees of motion is a bit tough if I had to have the jeep, APM and radio receiver all connected at the same time.
My attempted alternative was to rotate the APM by itself and then connect the actuator and receiver after the rotating step. Unfortunately the APM disconnects from Mission Planner when I start connecting the radio and receiver.
