Radio-controlled aircraft

Radio-controlled (RC) aircraft are planes or helicopters that can be controlled remotely. Inside the plane or helicopter is a small receiver, which is like the brain of the aircraft. The receiver picks up signals from a transmitter that you hold in your hands. These signals control the motor and servos (small motors) inside the aircraft, telling it what to do and how to move. You can make the plane or helicopter fly around in the sky and do lots of cool stunts.
