Mine has been perfect, I ran the stock setup probably 6-8 times then stuck a MGM/1515 1Y in it on 14 cells. So far the only problem I've had was my own. I was running the truck without the body and slammed the brakes too hard. She did a forward flip and landed on the rear shock tower. The rear bulkhead snapped at the lower mount screws, a $8 set of new bulkheads later and its as good as new. Just a lesson to myself, never run it without the body.
