Update April 15: We are no longer taking pre-orders until we get more accurate information from Traxxas about when we can expect the vehicles we have already placed on order with them. We have tried to pass along the best information we can about availability and eta's but we are getting frustrated just as you are, and can not explain the continuing delays. We have an urgent inquiry into Traxxas and will update here with what we learn.
  • Unlimited Desert Racer: 4WD Electric Race Truck - FOX

    Unlimited Desert Racer: Pro-Scale 4WD Electric Race Truck. Ready-to-Race with TQi 2.4GHz Traxxas Link Enabled Radio System, Velineon VXL-6S Brushless ESC (fwd/rev), Traxxas Stability Management (TSM), and Licensed Race Replica Fox painted body.

    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. The Traxxas Unlimited Desert Racer faithfully captures the look and feel of Trophy Trucks and Unlimited Trick Trucks as they charge hard across the desert at full speed.

    Driving Realism

    The Traxxas Unlimited Desert Racer 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.

    6S Extreme Power

    The 50+ mph Unlimited Desert Racer 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.
