i have a savage x w/4.6. everything was working fine and all of sudden every now and then when i give it gas it did nothing. i lose throttle, brake and steering every now and then for a couple of secs then it will come back for a lil bit then do it again. i have tried everything, i pulled off the fail safe, brand new batteries in truck and controller, changed crystals, no cuts or anything in wires or antenna, even went out to an open pasture with no power lines or anything and that didnt do anything. but if i turn the electronics with out cranking it, it will work just fine. i even taped the batteries in to make sure they werent moving around. i believe its gotta be getting some kind of interference but i don't know how. i can even walk right up to the truck, point the controller to the truck and nothing. the truck is only a month old. bought in beggining of december.
