How to play RC toys?

Types of RC Toys

RC toys come in a large variety of models, including:

Cars

Trucks

Fantasy vehicles

Airplanes

Helicopters

Blimps

Sailboats

Motor boats

Submarines

Robots

Animals

While the mechanics of how they operate can differ greatly between different toys, the basic principle is the same. All radio controlled toys have four main parts:

Transmitter - You hold the transmitter in your hands to control the toy. It sends Radio waves to the receiver.

Receiver - An antenna and circuit board inside the toy receives signals from the transmitter and activates motors inside the toy as commanded by the transmitter.

Motor(s) - Motors can turn wheels, steer the vehicle, operate propellers, etc.

Power source

The transmitter sends a control signal to the receiver using radio waves (see How Radio Works for details), which then drives a motor, causing a specific action to occur. The motor in a car may cause the wheels to turn, while the motor in a plane may adjust the flaps. The power source is typically a rechargeable battery pack, but sometimes it's just normal batteries.

In many of the RC toys, the radio controlled motor provides guidance while another source of power provides the locomotion. Here are some examples:

A model airplane often has a small gas-powered engine to turn the propeller; the RC motor controls the flaps.

A sailboat uses the wind for propulsion; the RC motor controls the rudder.

A blimp uses helium or hot air for lift; the RC motors control small propellers.
