I used a bench grinder to cut the teeth off of the hyper 7 diff's ring gear, I just cooled it with water after it started to get hot, also the revo plasic gears won't work, the teeth count is incorrect, you need the gear from the traxxas CD or mod the original lower gear like Mc did. Don't forget the (1) 8X12 bearing for the one end also.
