Had an interesting thing happen on my biplane a couple of days ago. The HD-1501MG servo on my rudder went from zero degrees on takeoff to about 20 degrees right shortly after takeoff. I did have one do that last year on my elevator, it went to about a 20 degree up elevator position and I replaced the servo.

I checked the rudder servo torque to see if any of the gears were stripped, everything seemed okay. I just repositioned the control arm and flew another flight. The right and left range were not changed, the movement was okay in both directions. It worked okay and zero didn't change again. I'll replace the servo before my next flight.

Seems strange that the servos would do this. Has anyone else had this happen?
