The extreme environment of race and freestyle quads demands something stronger. For years, Quadrysteria manufactured its quad frame kits from T300 based carbon fiber plates -- the typical fibers used in the hobby industry. Now, Quadrysteria has partnered with a leading manufacturer of carbon fiber to develop a T700 based plate that is super-strong, yet still suitable for fine machining. Dubbed QXC carbon fiber, these plates are constructed using a twill weave of the highest strength standard modulus fibers available - T700*. These never-twisted carbon fibers are prepregged then bonded into a high strength armor plate. You will find QXC carbon fiber plates in all our "V2" kits -- starting with Crossbones, RUSH 4 and RUSH 5 kits and parts.
