Losi Lasernut U4 1/10 4WD Brushless Rock Racer with 2.4GHz Radio and Smart ESC (Black)

The Losi Lasernut U4 1/10 4WD Brushless RTR Rock Racer is a scale replica of the renown Lasernut Unlimited U4 FIS (Full Independent Suspension) rock race buggy. Starting with the Losi TEN platform as a base, the Lasernut model adds items rock racers demand such as aluminium shocks, sway bars and adjustable turnbuckles. Working together with BFGoodrich Tires, the Lasernut U4 has scaled down KM3 tires that have an aggressive tread pattern that is capable of tackling a wide variety of terrain - from dirt and sand to chunky rocks and slick slabs.

The Lasernut is currently the only complete Unlimited U4 FIS 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 colour variations. The Losi Lasernut Rock Racer is the ultimate U4 racer with scale looks, insane speeds and performance.
