Remote-controlled cars are miniature vehicles that can be operated from a distance using a handheld transmitter. These cars come in various styles, including racing cars, trucks, and off-road vehicles. They are powered by batteries and can be used for fun, racing, or even as a hobby for enthusiasts. The technology behind remote-controlled cars typically involves radio signals that allow the user to control the car's movements, such as steering and speed. Many models are designed for both indoor and outdoor use, making them versatile toys for people of all ages. Popular brands include Traxxas and HPI Racing.
