KYOSHO USA-1 Nitro KE25SP
READYSET: 33155B
The original Kyosho Nitro USA-1 set the standard for RC Monster Truck power and performance when it was released in 1990. 30 years later, the torch has passed to the newest Nitro USA-1, which outperforms the original in EVERY respect. Yes, it's that much better… and we even build it for you.
Built on a pickup truck chassis, large diameter tires and big engines with massive horsepower were installed by fun-loving American off-roaders to create the monster truck. These ever-popular monster trucks can be seen on specially-made racing circuits or jumping rows of cars in stadiums across the USA. Many R/C monster truck models have been produced over the years. First among equals is the legendary 1/8 scale USA-1 that embodied the might of American trucking power during the 1980’s and 90’s. Officially licensed by Kyosho in the 1990’s, the R/C model uniquely captured the power and glory of the USA-1. Now it’s ‘comeback-time’ for the USA-1, with modern chassis and drivetrain technology, upgrades unique to the USA-1 throughout, and a newly-designed ‘ULTRA SCALE BODY’ with form and detail finished to display-model standards. The iconic American flag graphic emblazoned on the body makes your heart swell with pride! The chassis features shaft-driven 4WD and 5-link suspension based on the Mad Crusher 2.0 & FO-XX models. Most of the suspension components have been uniquely upgraded and reinforced for the USA-1 at each point to handle the powerful new KE25SP2 engine, and the rigors of monster trucking. A 3-speed automatic transmission produces dynamic acceleration, which is enhanced by a true suspension system to produce "scale" running characteristics worthy of the prestigious USA-1, and make you feel like a monster truck driving god. Released as a pre-assembled Readyset, the USA-1 is almost ready for action straight out of the box.
