LOS04019 Super Lasernut U4 Rock Racer RTR
No se pudo cargar la disponibilidad de retiro
Ultra4 racing is a unique mix of off-road motorsports. There are challenging rock trails that require precision and torque. The desert floor is filled with ruts and whoops to conquer at 80 mph speeds. Then comes the dry lake bed, where the pedal hits the metal and the top gear gets you over 120 mph. Breakdowns are inevitable, but the clock doesn’t stop for repairs. Ultra4 is the ultimate form of off-road competition!
The ready-to-run Losi Super Lasernut reproduces one of Ultra4 racing’s most successful vehicles — Cody Waggoner’s incredible Lasernut U4 — in highly detailed, high-powered 1/6 scale. Anyone who’s an extreme off-roader at heart will feel their pulse race when experiencing its perfect blend of performance and scale realism. You’d never expect that this is also Losi’s most affordable large scale buggy.
For drivers with a competitive streak, one of the biggest highlights is an independent suspension based on the ROAR Nationals winning platform, the TLR 8IGHT. It’s quite possibly the best suspension available for desert racing’s style of cornering and jumping.
Other standout features include a rugged, all-metal 4WD driveline built to handle extreme off-road terrain, and a 6S-capable Spektrum brushless power system that delivers top speeds in excess of 50 mph. Spektrum radio equipment is also included that offers the unmatched advantages of Smart technology for exceptional performance, convenience, and reliability.
Because the Super Lasernut shares the same platform as championship-winning TLR 8IGHT racing buggies and truggies, it also accepts many top-of-the-line TLR option parts. If you enjoy using your mechanical skills to get results, wait until you see what you can do with the Super Lasernut. Next-level racing performance is only a few well-chosen upgrades away.
One look at the factory-finished body proves that Losi made no compromises in bringing the Lasernut U4 to 1/6 scale. From the helmet air hoses and fire extinguishers to safety nets and more, everything you’d expect to see on an Ultra4 racer is authentically reproduced. A functional LED lighting system ensures that the fun won’t stop when the sun goes down. Of course, Losi also secured partnerships your favorite full-size off-road manufacturers in order to add numerous officially licensed details.
While the Super Lasernut is at home on the trails, in dirt lots, and in any large open areas, it lives for desert action where you can put yourself in U4 race driver’s seat. Take it along with your quads, dirt bikes, and UTVs, for some fun back at camp with your family and friends.
Get the ready-to-run Losi Super Lasernut 4WD — and experience 1/6 scale off-road racing easily, affordably, and in the extreme.

METAL WHERE IT COUNTS
Losi designers approached the Super Lasernut with the same attention to reliability and durability that full-scale manufacturers give their off-road vehicles. Rugged, damage-resistant metal parts are used wherever extra strength is needed to handle the stress of high-speed driving over harsh, ever-changing surface conditions.
FULL-METAL DRIVETRAIN
From the axles to the ring and pinion and main center spur gear, every part of the driveline is made of heat-treated steel to withstand off-road abuse. Its strength and endurance have been put to the test in demanding, hour-long racing main events and proved up to the challenge!
ALUMINUM SHOCK TOWERS
Lightweight and strong, the aluminum shock towers support the shock movement needed to absorb bumps and maintain tire traction. Use the tuning holes to find the best shock position for the surface and your driving style.
ALUMINUM ADJUSTABLE SHOCKS
The threaded shocks let you adjust ride height to raise or lower the center of gravity for optimum handling. The shocks can be tuned for harder or softer damping using different pistons, springs, and oil (all available separately).
ALUMINUM CHASSIS
Its 4mm thick aluminum chassis gives the Super Lasernut a stable foundation, along with the strength necessary to keep going through long stretches of punishing off-road racing.
ALUMINUM SPINDLES
The durability of its aluminum spindles lets you steer the Super Lasernut through rough terrain with confidence.
STEEL TURNBUCKLES
Adjustable steel turnbuckles absorb the angled impact while cornering and let you tune camber and toe for the best handling characteristics.
INDUSTRY-LEADING ELECTRONICS
The radio equipment and brushless power system included with the Super Lasernut take advantage of state-of-the-art Spektrum Smart technology for exceptional performance, convenience, and reliability.
OVERSIZED STEERING SERVO
The massive torque (555.50 oz-in @ 7.2V) of a factory installed, large scale Spektrum S905 servo keeps your Super Lasernut steered in the right direction over difficult terrain. An aluminum servo horn is included for durability.
SPEKTRUM SMART ELECTRONICS
Spektrum Smart electronics make you aware of potential issues before they become problems. You can receive important telemetry data in real time, right at your fingertips, by downloading the free Spektrum Dashboard app to your mobile device and adding the BT2000 Bluetooth Module (available separately) to the included DX3 transmitter.
SPEKTRUM FIRMA 150A SMART V2 ESC
In addition to offering Smart telemetry capabilities, the Spektrum Firma 150A Smart V2 waterproof ESC turns the 22.2 volts of power coming from your 6S LiPo battery into terrain-ripping speed as soon as you punch the throttle.
SPEKTRUM FIRMA 4074 2050Kv BRUSHLESS MOTOR
Add a 6S LiPo battery, and the installed, fully sealed, maintenance-free Spektrum 2050Kv brushless motor delivers more than enough raw power to get every driver’s adrenaline pumping.
SPEKTRUM DX3 2.4GHz SMART DSMR TRANSMITTER
The throttle limiting function on the included Spektrum DX3 2.4GHz transmitter lets novice racers limit the buggy’s top speed to 50% or 75% of its full potential until they’re ready to unleash it all. Using a Smart battery, you can follow how much capacity is available on the transmitter’s Smart battery level indicator.
SPEKTRUM SR315 3-CHANNEL DUAL PROTOCOL RECEIVER
When you want more precision from your electronics, there’s no need to install a new receiver. The included Spektrum SR315 receiver not only gives you the benefits of Smart technology, but with a transmitter upgrade will allow you to tune on-board electronics wirelessly with forward programming.
TRUE RACE SUSPENSION GEOMETRY
If you’d like to learn about suspension dynamics, the Losi Super Lasernut gives you the perfect opportunity. You’ll be able to tune the suspension for the exact handling characteristics you want, with adjustable camber, camber rate, shock angle, ride height, and more.
THREE SEALED OIL-FILLED DIFFERENTIALS
The front, center, and rear differentials allow each tire to use the motor’s torque to deliver maximum racing traction. You can tune the differentials with TLR silicone diff fluids (available separately) to adapt the Super Lasernut to different conditions.
SWAY BARS
Front and rear sway bars are standard on the Super Lasernut. They keep the chassis stable and level with the surface as you race through the corners.
ADJUSTABLE CAMBER & TOE
The robust steel camber links and tie rods are quick and easy to adjust, letting you tune the way your Super Lasernut enters and exits the corners.
ACCEPTS TLR UPGRADE PARTS
Because the Super Lasernut shares the same platform as championship-winning TLR (Team Losi Racing) 8IGHT racing buggies and truggies, you can use many TLR option parts to upgrade it for next-level racing performance.
BEST IN CLASS SCALE FEATURES
Go ahead. Look closely. From the air hoses and fire extinguishers to safety nets and more, everything you’d expect to see on an Ultra4 racer is authentically reproduced in 1/6 scale on the Super Lasernut.

OFFICIALLY LICENSED RACELINE RYNO WHEELS
In full-scale off-roading, Raceline Ryno wheels lead the way in performance, design, and durability. These are the wheels that Cody Waggoner has on his full-size Lasernut U4, and Losi includes officially licensed scale versions on the Super Lasernut.
OFFICIALLY LICENSED BFGOODRICH KR3 TIRES
Not only are the officially licensed BFGoodrich KR3 tires tough and realistic, but they also provide the Super Lasernut with relentless traction on the most extreme and demanding terrain.

DRIVER FIGURES
