Pro-Scale™ Performance

The Unlimited Desert Racer combines Pro-Scale™ performance with extreme 6s power for the most thrilling RC driving experience possible.

The UDR™ drives like a real desert truck because it’s engineered like a real desert truck. A 4-link solid rear axle provides huge suspension travel with authentic driving dynamics. From the cantilever sway bars and high-voltage lighting system to the GTR shocks, Traxxas accurately reproduced a true desert racer in both form and function.
