Radio-controlled vehicles, often called RC vehicles, are miniature models that can be operated remotely using a transmitter. These vehicles come in various forms, including cars, trucks, boats, and airplanes. They are powered by electric batteries or fuel engines, allowing for different speeds and performance levels. The technology behind RC vehicles involves a radio transmitter that sends signals to a receiver in the vehicle. This enables users to control the vehicle's movements, such as steering and acceleration. RC vehicles are popular for recreational use, racing competitions, and even educational purposes, helping enthusiasts learn about mechanics and electronics.
