The first all-electric-powered RC cars appeared in the U.S. in 1976 as plastic model kits by Tamiya. These model cars could be outfitted with a radio-control system, sold separately. At first, these vehicles had to run on smooth surfaces, but by the late ’70s and early ’80s, Tamiya had developed all-terrain vehicles as well. In the ’80s, American companies like Losi, Associated Electronics, and Traxxas (known for its T-MAXX and the REVO 3.3), as well as Tamiya and Kyosho in Japan, continually introduced innovations in radio-controlled model-car designs.

RC cars on the 1:8 scale tend to be two feet long by less than a foot wide, whereas 1:12 scale is approximately one inch to one foot, meaning the cars are generally 14-by-6-inches. Those on the 1:12 scale, which can attain speeds of 35 mph, are usually sold in pre-assembled or kit forms. Cars of 1:8 scale, which can go as fast as 50 mph and are favored by serious hobbyists, are generally built from scratch, as parts like bodies and brake systems are made by different manufacturers. Electric-power models come in four- or six-cell battery versions, too.

The radio systems, which can be adopted from those sold for model airplanes, are available in two- or three-channel formats. Generally, one channel controls the speed of the vehicle, while the other controls the steering. The FCC has sanctioned 19 channels for radio-controlled model cars, which can be operated without a license because the signals on the controls are so weak, only working when the car is within sight of the operator.

Toy radio-controlled cars sold at places like Radio Shack and department stores over the past few decades come in scales ranging from 1:12 to 1:24. While these generally offer less control over aspects like the degree of a turn, they often have fun features like working headlights. They also tend to move at slower speeds, so they are less dangerous for younger children.
