Radio control, often abbreviated as RC, refers to the use of radio signals to operate devices from a distance. This technology is commonly used in various applications, including model airplanes, drones, and remote-controlled cars. The operator uses a handheld transmitter to send commands, which are received by a receiver in the device, allowing for precise control. The basic components of a radio control system include a transmitter, a receiver, and servos or motors that execute the commands. RC systems can vary in complexity, from simple toys to advanced models used in competitive racing or aerial photography. The range and responsiveness of the system depend on the frequency and technology used.
