I've been racing the same SC10 for a couple years now and finally managed to snap a chassis. My son was checking out how dialed she was and jumped it slightly less than perpendicular into a plywood covered stud wall at a pretty good clip. The chassis snapped and the upper bulkhead bought the farm too so the truck was basically in two large pieces with the steering links holding it together. I should have taken a picture. I'm sure the RPM bumper would have had a better chance of surviving but this was a hard hit.
