Yeah,he thought it was the skid(center skid plate below the transmission),i wasn't totally convinced (because of the 2.4 ghz metal-metal thing) but he seemed to solve it so i guess it must have been.
Interesting, but I am not sure what a metal center diff housing has to do with causing interference? I have run other speed controls with the exact same setup and not had this problem, but I have also experienced this problem with my MGM. The MGM is known to have this problem though.
