I have an AR7200BX on a blade 360CFX. Both the normal and reversed setting in setup menu N causes the elevator servo to go full down. When I rotate the heli the swash tries to compensate instead of remaining stationary. I have called Horizon thinking I have a bad AR7200. They want me to send in the heli for them to evaluate the AR7200. I would like to avoid that if possible. Anyone have any ideas, could something else be causing this problem?
