Hi, I have ArduPlane 2.47b on an APM1 (all I have left, haha) in a glider.
Radio is calibrated. IMU is okay.
Problem: Ailerons are centered in all modes except MANUAL, no matter what I do with the sticks or how I move the plane around to get it to stabilize. The rudder, via aileron to rudder mix, does move with aileron input and roll stabilization in non-MANUAL modes.
The Servo Yaw PIDs inputs in tuning in MP are grayed out. I did not accidentally enable APM elevons.
What can that be?
