RE: Cessna out of control
Sounds like interference from something. Anyone else in your area have RC stuff. Or a bad receiver. I had one go bad like that once. Sitting on the bench it would work fine, but when I started the motor and ran it for a while the virbrations would cause it to clitch at times, not all the time but all of a sudden. Any way I hope you can fix it so she will at least get to breath the air up there.
