I was driving my RC today, and I guess it was going around 35MPH. And it went out of range, it reved. all the way up, to arbou 45MPH. Smacked right into a concrete parking lot curb. Ya know those things that have at each end of a parking space? It hit that pretty hard. It stalled. I panic'd, went to see the damage, the wheel just came off, and more of a crack to the front bumper. Put the wheel back on. Fix the bumber with some crack filler. I see some RC videos where they hit things at 50MPH, and seem not to do much damage other than a stall or light body damage... It really is crazy. If I hit my car into a concrete curb, I'm sure I would kill the rims, and damage something underneath...
