A stadium truck is a small, off-road radio-controlled car, either rear wheel drive (example: Traxxas Rustler) or four wheel drive (example: Arrma Vorteks 4x4).
Most feature wheels and tires that are both larger in diameter and wider for increased ground clearance and improved handling and stability.
The chassis of most electric powered models is constructed of plastic or a fiber/plastic composite while internal combustion powered models typically have chassis made of aluminum.
The primary difference is that the tires and suspension components extend far outboard of the body, similar to open wheel cars.
Although stadium trucks have no direct full-size counterpart, their name refers to types of full-size R/C vehicles that are raced on a closed circuit or stadium rather than a long, outdoor road course.
