Aluminum chassis with special cutout openings for increased flex. This framework is preferred for and works extremely well on low-to-medium traction songs. (Not recommended for very high traction conditions where in fact the #301143 - Aluminum Chassis increases results.) This new aluminum flex chassis creates more traction and makes the vehicle quicker and easier to drive. Effectively raced by Team XRAY, this is certainly a must have for each serious racer.
Due the character of this aluminum product together with machining procedure, it's normal that the framework can be somewhat bent in the longitudinal way.
