I wouldn't think battery wires would be your problem. Usually from esc/motor. This was very clear to me when running a MM esc, and a VXL esc in my old Rustler.

The mm esc is the reason I got my 3pm.

I mounted the receiver on the bulkheads just infront of the rear shock tower, mounter the ESC just to the right of the motor. Keeps the receiver well away from motor wires.
