I think most of you are on the right track. I had a similiar problem with a G62 I was flying in a Biplane every once in a while I would be flying and get a glitch my plane would do all kind of stupid stuff I swear I was getting hit, or some one turned their radio on , on my freguence. The correct way to range check a plane with a gas engine is to have the engine running antenna down walk off you distance and watch and listen to your plane throttle it up and down. At this point my plane went crazy thats when I realize it was my plane either something rubbing or my mag. After talking to a friend of mine he showed me these buffers that wrap around your wires going to the receiver I never had any more problems. Their 20.00 for 5 if anyone needs any more info you can email me at [email protected]
