XRAY - Model racing cars

I broke 2 set ad now change each liter new set frm avid. This is big xray problem, please dont say "it doesnt happend"

The only guys that I see breaking bearings/bulkheads locally are the guys that don't let off the throttle and nose into the ground almost every jump.

I've seen a factory driver of another brand, to remain nameless, sheer the front end off of his car when he nosed into the ground on a big jump.

8 lbs. going 20-30mph is never good when you nose into the Earth, learning to jump is just as important as learning not to hit the walls/pipe.

has anyone with this problem checked to see if their chassis is bent?
