DO not Do This!!!!!

It doesn't take a big car to leave a mark either, I had a HPI RS4 Rally that I dropped a Epic quad mag. 11x1 in (when they first came out) and was testing it out next to my house. I was hitting at least 35 or so, and this one mentally handicapped guy that lives at a house across the street came out to watch........he wasn't really paying attention to where the car was going and it slammed into his bare foot. It hit hard enough to leave a couple little cuts, from the front body clips (was running it without the body), and popped off a ball link. He was super apologetic and thought he killed my car, I was more worried about hitting his foot!
