I also sent a JR649 receiver back some time ago. It was not in a crash but it would evey now and then cause all of the surfaces to jitter. Range checks were always good both engine on and off but it still would jitter after the first flight and only on the second flight.. I tore my hair out replacing servos, extensions, batteries, etc... It cost me 15 bucks in shipping since the reciever was like this out of the package and was not damaged in amyway.
