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 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.

Features Overview

Legendary TEN Platform:
The legendary, high-performance TEN platform features a super-tough aluminum chassis and the ability to adjust the Lasernut U4 independent suspension and drivetrain for any condition.

Spektrum SMART ESC:
The ESC is waterproof, completely programmable and comes pre-wired with a high-current IC5 connector. The ESC will work with most sensorless brushless motors and is 3S-4S Li-Po compatible.

Officially Licensed Scale Body and Roll Cage:
A Lasernut Licensed race inspired scale U4RC body/roll cage with exciting graphics offered in two different color variations with a flip up cage for easy access to the battery.

Officially Licensed Wheels and Tires:
The included scale licensed Raceline 2.2 racing wheels and BFGoodrich KM3 tires featuring an aggressive tread pattern that handles any terrain and good looks while out on any course.

Waterproof Electronics:
The Lasernut U4 is loaded with waterproof electronics including the receiver, servo and ESC. Everything is sealed against the elements allowing you to splash in the rain, spin in the mud and make tracks in the snow. It's full-throttle freedom to run anytime, rain or shine

Aluminum Chassis:
The foundation of the Lasernut U4 consists of a 3mm, anodized aluminum chassis plate with a 4mm upper deck. Whether you are hitting the rocks, getting huge air, or just wide open, the 3mm chassis just keeps asking for more!

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.

50+ MPH Firma Motor:
The brushless Spektrum Firma 4-Pole 1900kv 550 Motor will provide excellent power (50+ MPH) with a 4 cell Lipo (not included).

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.
