Aluminum chassis with special cutout openings for increased flex. This chassis is recommended for and works extremely well on low-to-medium traction tracks. (Not recommended for very high traction conditions where the #301143 - Alu Chassis works better.)
This new alu flex chassis generates more traction and makes the car faster and easier to drive. Successfully raced by Team XRAY, this is a "must have" for every serious racer.
