RE: Aileron Servo's getting stuck?
I would also say sounds like the RX. It could also be a servo extension if you used the same one both times. I recently sent a RX to Hobby Services. The called me back with a list of problems. The RX was out of warranty so they offered me an exchange. I got a new RX with a new crystal for $40. The old RX had already cost me a $100 replacement Funtana wing. So don't take a chance on it.
