Having some problems with the ailerons. When flying if you let go of the stick she does a drastic hard right turn. You can also see they are not centered when on the ground. I would hate to loose aileron control while in the air. Any information would be great.
Any sudden change in roll trim when no rigging changes have been made is likely caused by a shape change in an aileron (this can happen by someone aggressively squeezing one of your ailerons).
Use a straight edge to check for proper trailing edge shape as described in paragraph 5.7 in THIS document.
