Aluminum T419 framework with original cutout areas for increased flex. This chassis is recommended for low-to-medium traction songs because it produces more traction. (perhaps not encouraged for high- and very-high traction conditions in which either the #301149 or #301150 chassis are better). Leading brace which will be frequently easily set up on the framework with two screws eliminates part flex in front of this framework, increasing steering effect and making the automobile more predictable. Efficiently raced by the factory team, and employed by Bruno Coelho to win the World Champion title, this really is a must have actually really for every serious racer.
