with a proper driver and driver bits, and knowledge of ow the truck is assembled, the truck is very easy to work on. i have personally taken a diff out and put it back in within 15 min.

i ran an MMP/lrp 5.5 550, with a xp ds 1015, with no problems glitching for 2 months. it would stutter while hammering the throttle up and down the street though, because of the high traction and such. i switched to the xerun 120amp v2.1... it is a better esc with better programing options, and its cheaper too.
