The CARSON drive concept for TAMIYA® Trucks on a scale of 1:14.
Convert your TAMIYA 2- or 3-axle TAMIYA tractor to an all-wheel drive all-rounder with our self-locking axles. The components can be easily replaced as they are mounted on the existing mounting points. A huge advantage of these axles is that no additional space is required for a shift servo (linkages and Bowden cables), as this locks automatically in the event of loss of traction.
