I?m flying Dynon HDX and autopilot. Everything works. After 30 minutes or so enroute I notice my aileron trim has moved over to the left by the AP auto trim function. Why? What is it telling me? I feel the stick and can?t really feel the need to have trimmed left. Plus I think it is flying right wing slightly higher. Might the springs on the servo not be balanced exactly equal? Or might I have a heavy wing do to fuel unbalance? I move the trim back to center and I think the right wing lowered a little. The trim stays there for awhile. I haven?t noticed when it auto trims left again. If you?ve seen this before what do you think is causing aileron auto trim to move? With AP off my RV-7A is pretty hands off stable. So I thought it was trimmed out but ?.. AP auto trim is moving stick left I wonder why?
