Losi Lasernut U4 Brushless 1/10 4WD, Blue
Product Overview
The Losi Lasernut U4 Brushless 1/10 4WD, Blue is a high-performance electric rock-racing vehicle designed for drivers who enjoy challenging off-road terrain, fast trail runs, and technical driving. Inspired by full-size Ultra4 racing vehicles, the Lasernut combines a realistic tube-frame appearance with a capable 4WD drivetrain, long-travel suspension, and brushless power.
Its 1/10-scale platform is built for more than appearance. The Lasernut features a solid rear axle, independent front suspension, oil-filled shocks, metal drivetrain components, and a durable aluminum chassis, giving it the hardware needed for rough trails, rocks, dirt, and jumps.

Ultra4-Inspired Design
The Lasernut U4 takes its styling from Ultra4 rock-racing machines, which are designed to combine high-speed desert racing with technical rock crawling.
The realistic tube-frame body structure, cockpit, driver figure, roof, bumpers, and off-road details give the Lasernut an authentic race-car appearance. The Blue finish adds a distinctive look while maintaining the aggressive character of the platform.
Brushless 4WD Performance
The Lasernut is equipped with a Spektrum Firma brushless power system designed to provide the torque needed for technical terrain while delivering strong acceleration on open trails.
Its 4WD drivetrain continuously sends power to both axles. This helps the vehicle maintain forward momentum when climbing, crossing loose surfaces, or navigating uneven terrain.
The brushless system also offers lower maintenance requirements than a brushed motor and is well suited to repeated high-load operation.
Suspension for Technical Terrain
The Lasernut combines independent front suspension with a solid rear axle and four-link suspension. This configuration provides a useful balance between steering precision and rear-axle articulation.
Long-travel suspension allows the wheels to follow uneven terrain while oil-filled coil-over shocks help control compression and rebound. The suspension can also be tuned to suit different terrain and driving styles.
Durable Chassis and Drivetrain
A rigid aluminum chassis provides the foundation for the Lasernut's drivetrain and suspension. The vehicle also uses metal components in key drivetrain areas to better withstand the torque produced by the brushless system.
The combination of a durable chassis, 4WD transmission, solid rear axle, and metal drivetrain components makes the Lasernut well suited to demanding off-road use.
Spektrum AVC Technology
The Lasernut uses Spektrum Active Vehicle Control (AVC) technology to help maintain stability during acceleration and cornering. AVC can make high-speed driving easier to manage by making rapid steering corrections when the vehicle begins to lose its intended line.
Drivers can adjust the amount of assistance according to their preferences, allowing the system to be useful for both newer drivers and experienced hobbyists.
