The CARSON drive concept for 1:14 scale TAMIYA® trucks
Convert your 2- or 3-axle TAMIYA tractor to an all-wheel drive all-rounder with our self-locking axles. The components are easy to replace as they attach to the existing mounting points. A huge advantage of these axles is that no further space is required for a switching servo (linkages and Bowden cables), as these lock automatically in the event of a loss of traction. Officially licensed by ZF Friedrichshafen AG.
