The immensely popular M-chassis has been thoroughly reengineered. The resin semi-monocoque frame has new R/C unit positions for a lower center of gravity and optimum chassis balance. Mounted on the redesigned front section is a skid-type bumper to prevent damage from crashes. The 4-wheel double wishbone suspension system features transparent CVA oil dampers with new angled positions for improved efficiency. The 3-piece steering linkage ensures excellent stability during cornering. The PRO-spec chassis comes standard with a variety of high-performance Option Parts such as aluminum servo horn and aluminum rear uprights.
