CNC-machined from Swiss 7075 T6 aluminum, this X1 framework contains special cutout spaces for increased flex. This chassis is preferred for and works well on medium and high-traction tracks; not recommended for very-high traction conditions, in which the #371016 Aluminum Chassis increases outcomes. This aluminum flex framework creates more traction and provides enhanced steering. Utilized effectively by Team XRAY at many events, this chassis is a must have for every serious racer. 24mm narrower than previous framework variants, eliminating reference to the track in corners while rolling, and supplying improved cornering price. Includes a slot for a composite battery pack backstop makes it possible for 5mm battery pack place modification with all the most frequently used cross-chassis positioning configuration. To be used with #371148 aluminum rear pod plate.
