Ive owned my xmod for about two years now. All of a sudden when I turn the steering wheel on the controller the wheels spin forward as if im hitting the throttle! Anbody have a clue as to why this is happening and how I can remedy it? I took the controller apart and couldnt see any visible obstructions or anything obvious. I havent done any kind of upgrading other than your average radio shack add-ons. Any ideas? Thanks.
