While there are differences in how radio-controlled toys operate, all of these toys have four main parts. The transmitter is the control you hold in your hands. It sends radio waves to the receiver. The receiver is an antenna and circuit board that is located inside the toy that gets signals from the transmitter, which initiates motors in the toy. The motors work to turn the wheels and steer the toy. All radio-controlled toys have a power source, which is typically batteries.
