Adjustable wheelbase - Thanks to its adjustable wheelbase, it is possible to adapt a large number of bodies on the CRX2 Multi-position frame.

0° The new stub axles as well as the new CVD driveshafts make it possible to have an Ackerman angle of 0°. When cornering, the wheels remain parallel which improves the steering angle and manoeuvrability of the model.

Battery support - It is possible to choose different positions for the battery depending on the desired performance and weight distribution. The system also allows the use of different battery sizes and formats.

Anti Torque Twist System - To avoid the Torque twist effect (wheel that rises when accelerating), the new transmission allows the central driveshafts to turn in the opposite direction. The CRX2 can scale with much more stability and efficiency because of this feature.
