Radio control

Radio Control (RC) is a way of controlling toys or other objects from a distance using a special type of radio signal. RC is used in lots of different kinds of toys, like cars, boats, and airplanes. It works by sending a signal from a transmitter (a remote control) to a receiver on the toy that tells it what to do. The transmitter sends the signal over the radio so it can be picked up by the receiver, and the toy does whatever the signal tells it to do. RC is really fun, because you can control the speed and direction of the toy from a distance!
