Hey guys I need some help. The range on my Merv has slowely goten worse since I got it a couple months ago. I can only drive the car about 15 yards away before its out of range. I have replaced the batterys in the controller many times and that does nothing. I checked the anntena on the truck and there is a metal rod on the end of the wire that sticks up about half way through the tube. I have a VXL Summit and there is a wire on that one that folds over the top. Any Tips?
