CNC-machined from Swiss 7075 T6 aluminum, this X1 chassis contains special cutout openings for increased flex. This chassis is recommended for and works extremely well on medium and high-traction tracks; not recommended for very-high traction conditions, where the #371016 Alu Chassis works better. This alu flex chassis generates more traction and gives improved steering. Used successfully by Team XRAY at numerous races, this chassis is a “must have” for every serious racer. 24mm narrower than previous chassis versions, eliminating contact with the track in corners while rolling, and offering improved cornering speed. Includes a slot for a composite battery backstop which allows 5mm battery position adjustment when using the most frequently used cross-chassis alignment configuration. For use with #371148 alu rear pod plate.
