Come to find out it was the rear diff ring gear had just the very tip of a few teeth chipped off and with the extra strain of the driveshaft hooked up caused it to jump those teeth. Take the driveshft out and there wasn't enough strain to jump the teeth...kinda strange I know. Replaced both diffs with all metal arrma upgraded gears and no problem since.Did you ever get this figured out? I'm having the same problem and I'm even using a bigger motor and ESC.
