I have an old wrangler that its mostly stock and running on 12V. I upgraded the motors to theDuratrax 550. They run faster on flat ground but once you hit a hill or grass they bog down and stall. The wiring is also overheating. The motors has a pre-installed 19t pinion that matched the stock tooth and pitch but were plastic instead of steel. The new setup is extremely loud. this is leading me to think it's something mechanical causing the power and heating problem. anyone have experience with these?
