I purchased the Mad Bull Special Edition kit about a year and a half ago, and it is still my favorite R/C car for bashing in parking lots or gravel. With the stock motor it didn't do terribly great in tall grass, but I upgraded all of the stock bushings to ball bearings and put an ESC and a 15T Team Orion motor in it. The thing FLIES on asphalt and does wonderfully offroad. As far as durability, the only thing I've ever broken was the body since it is made from hard, brittle plastic rather than lexan. I'm actually going to be selling it within the next few days since I don't have any time for bashing with my onroad racing taking up all of my time. Know anybody interested in buying one?
