Take a look at the "Other RC Classes" There is a good HPI Micro thread going on in there. I will close this, please ask all your Q's in there

As for the car itself, i was lucky enough to take one for a spin at the Chicago Hobby Show. The car rocks! It drives a lot like a touring car, not like a mini. I would have to say the car is pretty tough. When i was there, they had plent of Boy & Cub Scouts that used them after i had, and let me say they need some practice
After seeing a couple head-on...full speed collisions, i would assume it is pretty tough.
