TRAXXAS UNLIMITED DESERT RACER 6S 4WD WITH LIGHTS – BLUE

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

6S EXTREME POWER

The 50+ mph UDR delivers its pro-level performance with brutal 6s power. The VXL-6s ESC combines massive power handling with high-tech telemetry features. An ultra-tough drivetrain harnesses the extreme power to make it easy to control and fun to drive.

DRIVING REALISM

The Traxxas UDR™ is engineered on an authentic, true to scale 4-wheel drive desert race truck chassis. The 4-link solid rear axle design provides huge suspension travel with authentic driving dynamics. From the cantilever sway bars to the 8 GTR shocks, Traxxas has accurately reproduced a true unlimited desert race chassis in both form and function.

PRO-SCALE® PERFORMANCE

Pro-Scale is a new Traxxas innovation that captures true-scale realism and combines it with extreme 6s LiPo power and 50+ mph performance.
