off road is where ive done most of my driving/ testing. and yes i do agree with you...the rc companies use crap cf and its basically just for looks, structurally its garbage. there are many different kinds, the 2x2 twill is what i have pictured and is some of the strongest. breaking and shattering has to do with poor quality products. there is a very specific procedure you have to follow in order to get the right resutls from any composite material, especially carbon fiber. my test results are based on high quality , and highly expensive prototypes. 1 chassis of this caliber costs roughly 350$ based on materials and labor. its this expensive, because there is a global shortage of carbon fiber, and decent composite fabrics are hard to come by and very expensive costing 50-100 dollars a yard, compared to fiberglass which is 3-4$ a yard. carbon fiber is far superior to aluminum in many many ways, but unless youve got the dough for GOOD cf, stick to aluminum.
