Aluminum T419 framework with exclusive cutout areas for increased flex. This framework is advised for low-to-medium traction songs as it produces more traction. (maybe not inspired for high- and very-high traction conditions through which either the #301149 or #301150 chassis are better). Leading brace which will be often effortlessly arranged regarding the framework with two screws removes component flex before this framework, increasing steering effect and making the auto more predictable. Effortlessly raced by the factory team, and used by Bruno Coelho to win our planet Champion title, that's a must have actually really for each and every and every serious racer.
