1/7 Unlimited Desert Racer Ready to Run (Rigid 2025) (TRA85086-4-RGD1)

The Traxxas Unlimited Desert Racer delivers the ultimate combination of scale realism and high-performance desert racing capability. Built on a Pro Scale 4WD chassis, this ready-to-run race truck faithfully recreates the aggressive design and dynamics of full-size Trophy Trucks and Unlimited Trick Trucks. Powered by a Velineon VXL-6s brushless system and 2200 Kv motor, it delivers blistering speeds of over 50 mph with 6s LiPo power, while the rugged 4-link rear suspension and double-wishbone front suspension provide massive travel for soaking up the roughest off-road terrain.

This desert race truck is equipped with twin GTR shocks at each corner for unmatched damping performance, functional sway bars and limiter straps, and a robust solid rear axle for true-to-scale driving behavior. The inverted tub chassis design lowers the center of gravity while allowing easy access to internal components, and heavy-duty skid plates and bumpers protect critical areas from harsh impacts.

The Unlimited Desert Racer comes loaded with scale details including a highly realistic cockpit with driver figures, functional spare tires, a spare driveshaft, fire extinguishers, jack, and replica brake components. The Pro Scale body attaches to the tube chassis at multiple points for strength and long-term durability without traditional body clips.

Its integrated LED light system features 204 high-intensity LEDs powered by a high-voltage amplifier for reliable, flicker-free illumination. The lighting system includes bumper-mounted light bars, a curved roof bar, and a multifunction rear light bar with brake and class lights that respond in real time.

The TQi 2.4 GHz radio system includes a 2-channel transmitter and 5-channel micro receiver with integrated telemetry and fail-safe functionality. The system supports the optional Traxxas Link Wireless Module (sold separately) for app-based tuning and telemetry display. With Traxxas Stability Management, the Unlimited Desert Racer maintains control on loose surfaces without sacrificing performance or fun.

The steel-gear direct-drive transmission with Torque-Biasing Center Drive and all-steel drivetrain components ensure durability under extreme loads. The innovative battery compartment allows tool-free access and supports single 4s or dual 2s/3s LiPo battery configurations, secured by a heavy-duty locking strap and protected by a reinforced skid plate.

From the finely sculpted tube frame chassis to the BFGoodrich KR3 replica tires on beadlock-style wheels, every detail has been crafted for realism and built for performance. Whether tearing through desert trails or lighting up the night with its advanced LED system, the Traxxas Unlimited Desert Racer sets a new standard in scale off-road racing.
