From Kyosho:
The famous USA-1 rides high again with this latest 1:8-scale model produced under license of the USA-1 4X4 Monster Truck team. The completely new Ultra-Scale body has been recreated with the precision details that uniquely make it the USA-1 Monster Truck. It sits atop a modified super-tough chassis equipped with a realistic and robust solid axle suspension front and rear, which can be converted to 4-wheel steering with some optional parts. With modern power systems to match the USA-1 in both name and performance, this package sets new standards of brute power compared to the original Kyosho USA-1 RC trucks. The only question is which one; Nitro or Brushless electric power?

In the early seventies, auto makers began to offer four-wheel drive in passenger trucks where it had previously just been available in agriculture and industry. It wasn’t long before enterprising performance enthusiasts like Everett Jasmer and a small handful of others started modifying their trucks for increasing levels of performance. This was the genesis of a friendly rivalry that, over time, would motivate an escalation of performance and innovation that eventually led to what we know today as the Monster Truck. Everett Jasmer emerged from this rivalry as one of the God Fathers of Monster Trucks, and the USA-1 as one of the most revered Monster Trucks of all time. It remains one of the inspirations for modern monster trucks and their fans around the globe even to this day.

Using the famous team USA-1 monster truck as the blueprint, Kyosho immortalizes one of the greatest trucks to inspire the phrase “Monster Truck” with an all-new version of the USA-1 as an Ultra-Scale body. In addition to its stunning details, it also features easy installation of optional LED light sets that help bring an even higher level of USA-1 realism to the RC community.

This machine shouts ‘red, white and blue’ with pride!

Featuring the inspirational stars and stripes of the American flag, the livery keeps faith with the true USA-1 machine.

SPECIAL ORIGINAL FRONT GRILLE

Highly detailed injection-molded parts such as the headlights and the grille, are attached to the polycarbonate body, which is ready for an easy installation of the optional LED lights. The chassis-mounted front bumper recreates the look and feel of the real truck. Many of the body details are original designs from USA-1 4X4, Inc., which are reproduced in great detail by Kyosho based on the famous 1988 monster truck.

REAR FACE

Like other unique aspects of the USA-1 styling, the rear end has been accurately recreated with the tail lamps that are also ready for optional LED installations, and like the front end, the injection-molded heavy-duty chrome rear bumper provides an extra level of scale detail that is uniquely vintage “USA-1.”

DOUBLE-TUBE LIGHT BAR and OFF-ROAD LIGHTS

A row of five off-road lights are mounted on the chrome double-tube light bar just as they appear on the actual monster truck. Even the light covers represent those featured on the actual truck. Protector for the roll cage prevents damage if the truck overturns. Install optional LED sets (97054-4B x 3 and 97054-4CR x 1. One LED is not used), for a total of 15 lights.

REALISTIC CARBURETORS

Recreating the look of the 1,200+ horsepower engine, the triple Predator carburetors that mount to the top of the supercharger, are realistically reproduced and attached to the chassis.

WINDOW & SIDE-VIEW MIRRORS

Pre-painted body features clear windows and detachable chrome side mirrors.

NEW ‘MONSTER’ TIRES AND WHEELS

The USA-1 includes accurate reproductions of the 66-inch agriculture tires and white wheels that were featured on the real USA-1 throughout its career. Foam inserts are installed inside the tires to maximize handling on a variety of surfaces.

The chassis of the USA-1 is unique in that the axles and suspension links have all been modified to be thicker and stronger than those originally seen on the Mad Crusher. The chassis, with its solid axles, produces a more authentic driving experience with characteristics that are comparable to the real USA-1. The wheelie bar present on both versions of the truck, is essential given the large amount of power available regardless of which version, nitro or brushless electric, is chosen. It’s really not for show.

RIGID AXLE SUSPENSION

Front and rear axle housings have been reinforced to withstand increased crash impacts.

‘4-GEAR’ DIFFERENTIALS

The front and rear axles feature fully functional differentials, complete with four metal spider gears that increase durability and allow different rotation speeds between the left and right tires when turning, for more nimble handling and easier driving characteristics.

‘5-LINK SUSPENSION

Chassis features a combination of a newly reinforced 5-link suspension and 4WD system to efficiently and reliably transfer the breathtaking power of the engine to the ground.

BIG BORE SHOCKS

5-link rigid suspension and large-capacity oil shocks provide plenty of suspension travel to charge confidently over rough terrain. The big shocks work in combination with the huge tires to overcome even large obstacles.

THE NEW BRUSHLESS MOTOR & ESC

The newly-developed brushless motor in the USA-1 generates 300rpm more per volt than the previous version motor. In addition, the waterproof ESC (speed controller) with maximum voltage of 14.8V (2 x 2S Lipo packs), allows setting adjustment of braking power, punch force, cutoff voltage, etc.

BRUSHLESS MOTOR POWER & CHAIN DRIVE

Full power of the newly-designed brushless motor is reliably transmitted by the rugged chain drive. This version is equipped with a slipper clutch to protect the drive system from the brutal acceleration potential of the new and more powerful 4-pole brushless motor.

THE NEW ENGINE

Equipped with the new KE25SP2 engine, the easier-to-adjust low-speed needle produces more power than the previous KE25SP engine. Fitted with a pull starter, the engine settings have been optimized at the factory. You’ll also enjoy the exhilarating growl of the engine through the polished, light-weight tuned pipe.

BREAK-IN RING

The included engine “break-in” venturi makes it easier to break in the engine with less concerning about over-revving the engine, especially for first-time owners of a nitro-powered monster truck.

3PCS CLUTCH

Three-piece clutch shoe delivers superior durability and more precise clutch engagement regardless of the clutch shoe material. The clutch engagement RPM can be adjusted with the use of optional clutch springs (sold separately).

3-SPEED TRANSMISSION & CHAIN DRIVE

3-speed automatic transmission makes effective use of the nitro engine’s power band. A rugged chain-drive reliably and very efficiently transmits power from the engine to the front and rear axles.

DISC BRAKE

A disc brake system produces reliable and consistent stopping power in the nitro version of the USA-1.

FULL BALL BEARINGS

GP: Full ball bearing specs (21)

BRUSHLESS MOTOR POWER & CHAIN DRIVE

Full power of the newly-designed brushless motor is reliably transmitted by the rugged chain drive. This version is equipped with a slipper clutch to protect the drive system from the brutal acceleration potential of the new and more powerful 4-pole brushless motor.

DRIVE SHAFT

New universal center drive shafts front and rear are standard (also telescopic in front) ensures power transfer efficiency and prevents shafts from dropping out.

THE SERVO

Waterproof KS5031-09MW servo incorporates metal gears to handle the high torque needed to control this large and powerful vehicle. Equipped with a servo saver on the chassis to reduce the load from external forces.

PROTECTIVE RADIO BOX

Radio box safely protects the receiver from dirt etc.

4WS Conversion Set(MAW023)

A full-size monster truck in action is a sight to behold. With optional parts, this USA-1 model can be converted into a 4WS machine.

Universal Swing Shaft Set(MAW019)

Internal universal drive shafts for the front and rear axles deliver increased drive efficiency, durability, and easier maintenance. One set includes two shafts, one each for the left and right sides of one axle. Two pair are needed to convert both ends of the truck.

HD Aluminum Front and Rear Lateral Rod Mounts(Front: MAW028GM / Rear: MAW029GM)

Changing the chassis mount for the lateral rods to aluminum increases strength to withstand even harder driving.

CNC Wheelie Tire Set(MAW020)

The adjustable wheelie bar helps prevent the truck from flipping over backward under hard acceleration, and assists in riding an awesome wheelie over long distances. Made of machined, anodized aluminum.

PBR Oil Shock Set (MAW018)

Individually CNC machined aluminum reservoir oil shocks.

Light Bucket Set & LEDs(SCW017)

Adding LED lights to the light bar on the USA-1 is possible with these optional Light Bucket Sets (SCW017 x 3) and optional LEDs.
