Thanks for the help. My first instinct was the servo. It is not that old, but is not new either. It just kind of threw me off that the throttle was the only one that jumped. I have the servo mounted about 10 inches behind the ignition, and the reciever is about 10 inches behind the servo. I will definitely try and swap out the servo. There is no metal to metal contact between the control rod and the throttle arm. And pe rievers, thanks for the sarcasm. It is definitely not appreciated. I just asked a simple question.
10 inches may not be enough. I would move it back farther if you can, and then check it again before you change the servo. Also make sure not to use your Rx battery for ballast and put it up front. It can pick up RF also. If everything is well back from the engine, and you still have problems, I think you will have eliminated RF as a problem. Then you can look at the servo.
