Overview
The TEN 4WD platform is recognized all over the world as the personification of strength and durability. The Losi® Lasernut U4 1/10-scale 4WD Rock Racer (RR) RTR with Spektrum™ Smart builds on the TEN design and adds items rock racers demand such as aluminum shocks, sway bars and adjustable turnbuckles. Plus, it includes a full metric hardware package for worldwide compatibility. The Lasernut is currently the only complete Unlimited U4 FIS (Full Independent Suspension) racer on the market featuring all the technological advances drivers demand including the Spektrum Firma Smart 130A Brushless ESC and Spektrum Firma 4-Pole 1900kv 550 motor providing greater efficiency improving run times with increased power. Of course, the ESC is waterproof, completely programmable and comes pre-wired with a high-current IC5™ connector. Drivers stay in control with a DX3™ transmitter, a Spektrum AVC® receiver with steering priority, and an officially-licensed Lasernut race-inspired scale U4RC body/roll cage with two different graphics and color variations. Working together with BFGoodrich Tires, the Lasernut U4 has scaled down KM3 tires that have an aggressive tread pattern capable of handling any terrain. The Losi Lasernut Rock Racer is the ultimate U4 racer with scale looks, insane speeds and performance, and Spektrum Smart Technology.

LED Light Bar and Pod Lights
The fun doesn't stop even when the sun goes down with the Lasernut U4. A brilliant LED lights on the integrated light bar cast more than enough illumination for running at night. The pod lights are amber.

Spektrum™ DX3™ Radio System
The Spektrum™ DX3™ radio system offers advanced features like AVC control, a 3-position throttle limiting switch and travel adjust.
The Full-Throttle Freedom of AVC® Technology
The receiver's built-in AVC® (Active Vehicle Control®) traction control system works behind the scenes, making hundreds of throttle and steering adjustments per second, so more of the motor's power is translated into ballistic speed and acceleration instead of just flying dirt. The patent-pending AVC system adds a level of performance that simply cannot be found with any vehicle from any manufacturer other than Horizon Hobby. Like traction control in your full-scale vehicle, you can activate or deactivate the system on the fly and adjust the level of stability based on driving conditions. Any RC vehicle can go fast and with AVC you can go faster while maintaining optimum stability in all driving conditions.
