Xray X4F '25 Swiss 7075 Aluminum Flex Chassis. This optional chassis has been designed to be 0.5mm thinner than the stock chassis which increases how much the chassis will flex which can improve the overall performance of the chassis.
This high-flex aluminum touring car chassis enhances overall grip and handling by allowing controlled chassis flex, which improves weight transfer and traction, especially on high-bite surfaces. This increased flex helps the car maintain better contact with the track, reducing understeer and improving cornering stability.
*Tech Note: This 1.5mm chassis requires special low-profile screws (#XRA913300) for proper installation. Using standard countersunk screws may result in improper fitment and potential damage to the chassis or bulkheads.
