1/10 Lasernut U4 4WD Brushless RTR with Smart ESC

The Losi® Lasernut U4 1/10-scale 4WD Rock Racer (RR) RTR with Spektrum™ Smart builds on the TEN platform delivering a great out-of-the-box experience to be able to throw down in any 2.2 Unlimited class


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 Smart 130A Brushless ESC and Spektrum 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.
