i am having a problem with my rear tail motor was wondering if anyone else has had this. the tiny brass bushing that is behind the pinion gear keeps slipping out, this causes the tail motor to stop abruptly and jam up...sometimes it jams so fast that it actually breaks the pins off on the prop. it is starting to get annoying. the motor works fine except for this problem. when the bushing pops out it allows the pinion to move about freely causing the jam up. this does not look like the result of a crash...but who knows...if it was from a crash then tere should have been more damage than just the bushing right?
