RE: carbon fiber chassis
we put it on a stock revo that i bought with the chassi on and then sold it on e-bay, it looks awsome and it is a little less the half the weight of the standard chassis, althoe there are a fwe holes that were just a little bit off, and it is suposed to be stiffer than the stock chassis as well wich it seemed to be pleanty strong. at a race i have seen one guy brake his chassis by running into a car tire, but he was going probubly atleast 25 and the bounce just put a coupl little cracks all over the place. but if you looked athis chassis there were no visible cracks but hte second he hit the throttl hte chassis would bend up in the center and after about the 3rd time it just broke wright behind the engin ware the chassi straitens out. and sorrie about my messe up typeing, my keyoard is low on battarie
