In 1986, the first Hot Shot Junior of the Racer 4WD Series was released. The Hotshot was
Tamiyas first "Racing Buggy," and was extremely popular, leading to its redesign into a Mini
4WD car that could fit the palm of your hand. At that time, that design was greatly supported
by elementary school children. This led to the Mini 4WD evolving from just being 4WD models
to machines for use in a new type of racing hobby.
