Kyosho USA-1 VE 1/8 4WD Readyset EP (Torx8-Brainz8 ESC) (K.34257B)

The original electric USA-1 was the most popular Monster Truck in Kyosho history… A completely new version of the USA-1 comes 30 years later with more scale detail, freakishly more power, more durability, and more dynamic suspension. This is a game changer!

Born in the USA, the monster truck symbolizes America: big, bold and powerful! With pickup truck bodies emblazoned with dynamic motifs mounted on super tough chassis structures and big engines to power huge tires, monster truck racing filled and thrilled stadiums around America and the world with their awesome power and speed. Recreated in 1/8 scale as an R/C truck, the “USA-1” flies the American flag loud and proud as the recognized symbol of monster trucking. Dating back to the 1990’s, Kyosho’s earlier versions have been fully renewed with a newly created ULTRA SCALE body, uniquely reinforced 5-link suspension and stronger solid axles originally used on the Mad Crusher and FO-XX 2.0. Equipped with a high-power brushless motor with a 4-pole rotor and 12-slot stator generating 2300KV, the VE (electric power version) delivers outrageous speed and power characteristics that would rival that of the real USA-1. The high-powered unit produces dynamic performance that makes the large 570mm body length of the USA-1 feel smaller with acceleration pickup from a standing start surpassing that of the GP (engine powered) version. As a pre-assembled Readyset, the body is immaculately finished with paint and livery to capture the rich sense of scale of this iconic 1990’s machine. A charged motor battery and batteries for the transmitter are all that is required to start the action. With spare parts and a wide range of optional parts available to continually maintain and enhance performance, your USA-1 will provide thrilling fun over a long time.


  • Pre-assembled chassis with R/C system installed and finished body. Includes pistol-grip Synchro KT-231P+ transmitter.
  • Five-link suspension in combination with shaft-type 4WD delivers exceptional stability over rough surfaces.
  • Equipped with waterproof KS5031-09MW servo, incorporating high durability metal gears.
  • Ultra-realistic scale body has been recreated under license of USA-1, including the signature color scheme.
  • Optional LED light set shines bright with LED head & tail lamps and rooftop fog lamps.
  • Brushless motor unit is designed to handle a massive 14.8V. Optional twin motor setup is also possible.
  • Front center drive features a telescopic universal shaft to ensure high drive efficiency and prevent shaft dropout issues.
  • Optional 4WS (four wheel steering) increases turning power. A wide range of other options is also available.
  • Equipped with a wheelie bar to prevent the machine from flipping over backwards during hard acceleration. Enjoy the powerful action of the truck running on its two rear wheels.
  • Charger and battery for the motor, as well as 4 x AA batteries for transmitter are required for operation.
  • Engine-powered version using the same body and chassis components is also available.


4WD chassis with 5-link suspension system produces outstanding drive efficiency and performance so you can enjoy hard driving on the roughest roads with supreme confidence. This Readyset model comes with R/C system pre-installed.

Under license by USA-1, the newly developed polycarbonate body has been produced to a spectacular level of detail with separately molded accessory body parts including grille and lights to enhance the three dimensional effect. In addition, the chassis-mounted bumper captures the spirit and atmosphere of the USA-1 in all its glory.

Recreating the look and feel of the 1,000 horsepower engine, the triple carburetors that sat atop the supercharger on the engine of the actual truck, are replicated and attached to the chassis, and provide another level of scale detail that's faithful to the real USA-1 monster truck.

The newly developed 2300 KV KYOSHO SPEED HOUSE TORX8+ brushless motor generates approximately 4400 RPM at 14.8v than the previous TORX8 motor used in the Mad Crusher VE. The red color of the motor distinguishes it as the higher performance of the TORX8+ series.

Equipped with a KYOSHO SPEED HOUSE BRAINZ 8 waterproof ESC (speed controller). With maximum voltage of 14.8V (2 x 2S Lipo packs); settings for brake, advance angle, punch force, cutoff voltage, etc., can be adjusted. Separate programmer required.

Chassis is designed for 7.2V Ni-MH or 7.4V Lipo to be mounted on either side, but it is still possible to run the model with a single battery pack. The battery box accommodates batteries of various thickness and provides secure mounting, even under hard driving.

Large capacity Big Bore oil shocks reliably support the large chassis. In addition to the standard shocks and springs in the kit, a wide range of optional combinations provide various damping rates to suit different driving conditions.

Reinforced housing for the front and rear tires thrives under the increased power while improving crash resistance. Conversion to 4WS (four-wheel steering) can also be achieved with optional parts. The incredibly strong front and rear differentials come from a 1:8-scale world champion off-road racer and feature metal ring and pinion gears, plus four internal metal spider gears for the ultimate in durability. The differentials can also be tuned with optional silicone oil up to 1,000,000wt.

Five-link suspension system enables the long stroke to absorb the punishment from uneven surfaces for precision control and running performance. In addition, the rigid axle provides reliable transfer of drive force, even with the suspension fully activated.
