I've got some great footage from toady of two HPI Baja Trucks running on our track here, and I must say they are about damn bulletproof. I think they run forever on a tank of gas too, the guys would get tired of driving them or we'd run them off the track before they ran out of gas.
When I get the video together I'll upload and show you just how amazing those trucks are. They draw a crowd EVERYWHERE they go. People just stand there amazed. I marshaled for them for a while, but never really had to flip them if they crashed, 9 times out of 10 they land on their feet. They would hit the whoops and go about 8-10 feet in the air, and one would get so much air he would blow the wheel clean off the thing. I guess they are designed to blow out like that to keep from breaking parts, because he'd put some new clip on and be back on the track in no time.
