| Scale: | Speed: | Battery and Charger: |
|---|---|---|
| Pro Scale | 50+ mph | Not Included |
High-Voltage LED Lights
Flood the desert with high-intensity light from the rugged waterproof LED lighting system. A high-voltage amplifier powers 204 individual LEDs for brilliant light while tightly regulating the voltage to eliminate flickering and dimming. The rear light bar features class lights and smart brake lights that work when brakes are applied in either direction. Learn more >
Solid Rear Axle
The unique solid rear axle design of the UDR® combines with the 4-link geometry to eliminate torque twist. It puts 6s power to the ground like nothing else, tracking arrow straight while accelerating and then rotating on demand for effortless on-throttle power slides. The authentic true-scale driving dynamics challenge your skill behind the wheel in fun and exciting new ways.
Pro Scale® Realism
Traxxas Pro Scale design merges scale realism with extreme 6s performance, durability, and speed. From shock reservoirs, fire extinguishers, and fans to the functional spare tires and spare driveshaft, Traxxas elevates scale realism to a new level. At the same time, it’s been engineered for hard-charging 50+ mph desert racing action.
Secure Battery Compartment
A heavy-duty battery latch locks into place to secure batteries inside the compartment. An outer skid plate keeps debris out of the battery compartment and adds a second layer of security to help protect the batteries.
Rugged Tube Cage
The beautifully sculpted tube framework integrates fully with the chassis and suspension to form an incredibly strong, lightweight structure for the shocks and suspension components to mount. The realistic design even includes the “tin” panels so the race chassis looks just as good with the body off for pre-race practice runs.
Easy Access Design
The unique inverted tub chassis helps maintain authentic true-scale design while still allowing easy access to critical components underneath the truck.
Traxxas Stability Management®
Traxxas Stability Management (TSM)® keeps the front end locked on course, allowing the driver to accelerate hard and straight and even slide out the rear with confidence. TSM never kills the fun by cutting throttle or slowing down the truck. Adjust the amount of assistance from off to 100% right from your transmitter. Learn More
Twin GTR Shocks
Twin GTR shocks at each corner replicate full-scale desert truck performance in perfect scale detail while delivering a plush ride through deep whoops and the roughest sections of the course.
Pro Scale® Size
Only slightly shorter than the X-Maxx®, the Unlimited Desert Racer’s large footprint is right-sized to offer increased capability and 6s power-handling off-road, while still being easy and convenient to handle and transport.
Extreme Suspension Travel
The key to the Unlimited Desert Racer’s phenomenal off-road ability lies in its extreme suspension travel and ground clearance. The plush, seemingly bottomless travel is built to soak up whoops and washboard ruts with ease. The suspension does the work while the chassis remains steady and composed.
4-Link Rear Suspension
Massive trailing arms and heavy-duty linkages, along with the functional limiting straps, keep the solid axle firmly in control. The precision-engineered 4-link geometry rewards driver finesse with responsive and predictable handling as you rotate the truck and steer with the throttle through the tight sections of the course.
Heavy-Duty Steel Drivetrain
The drive system uses thick steel axles and an all steel-gear drivetrain to drive all four wheels. Heavy-duty center driveshafts transfer power to heavy-duty steel ring and pinion gears front and rear. 4-wheel drive delivers maximum acceleration off road.
Direct Drive Transmission
Large steel spur and pinion gears provide the ultimate in toughness and durability. The Torque-Biasing Center Drive distributes power between the front and rear drives for maximum traction on any surface. There’s no clutch to slip, just instant power on tap when you need it. The entire transmission and motor remove as a single unit for easy maintenance.
