PROBLEM: I was breaking in my new Magnum .52 XLS, and anything above 1/3 throttle, and the servos get the jitters, intermittently. What is weird, is if I moved my hand near the front of the airplane while the engine was on (the transmitter was about 5' in front of the plane), it would do it also, like maybe my wedding ring had something to do with it at times. I'm wondering if the throttle linkage, being a metal rod with a Z-bend going through the metal carb arm is vibrating so much that it is causing harmonics. It is a loose fit, and defineately is vibrating when the engine is running. This only happens when the engine is running, and only at 1/3 to 1/2 throttle. The flying wires I have are nylon, and the antenae wire exits the side of the fuse in front of the radio, and is attached to the top of the tail. What should I check, and in what order?
