Thanks for the thanks. I'm glad that solved your problem. One of the guys at my field had the same situation and after he had us scatter in the pits a couple of times, he finally landed the plane in one piece, luckily. A quick look inside revealed that he had his antenna tangled up with his servo wires. As soon as I cleaned up his layout, there were no more problems. Dan.
Whats weird is how it only happened when the motor was running. I wonder if this was a combination of isssues like everyone else suggested, vibration, the throttle rod, metal to metal etc?
This was a learning experiance and I hope others have learned something also.
