Has anyone had an issue with this double controller? I’ve been having a problem with the right steering wheel. When I turn it all the way to full forward power for a truck running on the track, the truck actually slows down. When I turn the steering wheel slightly to the left, the truck picks up speed. This hasn’t happen (yet) with the left steering wheel. It happens with all my vehicles. Can this problem be fixed? Does anyone know if there’s a video about repairing problems for this controller?
