How Radio Controlled Toys Work

You probably have seen the ads on television Saturday morning proclaiming the incredible capabilities of the “Super Ultra road-Rippin ‘ Devastator ‘ or some other control (RC, or car radio. And it is possible that you have seen people in the Park flying a model aircraft or blimp, or control of a boat sailing miniature serenely through a pond.
In this article, you’ll learn all about radio control. You will discover what frequencies are used for RC toys, which the different components are and how they all work together. You will also learn what is the difference between the radio control and remote control is time to talk of toys or models.

Types of RC toys

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

  • Cars
  • Trucks
  • Fantasy vehicles
  • Aircraft
  • Helicopters
  • Airships
  • Sailboats
  • Motor boats
  • Submarines
  • Robots
  • Animals

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

  • Transmitter – you takes place the transmitter in their hands to control the toy. Radio waves is sent to the receiver.


  • Receiver – a Board of the antenna and the circuit inside of the toy is receiving signals from the transmitter and activates the motors inside the toy as ordered by the transmitter.
  • Engine (s) – engines can turn the wheels, steer the vehicle, operate propellers, etc.


  • Power supply

The transmitter sends a control signal to the receiver via radio waves, which in turn drives an engine, causing a specific action that occurs. Engine in a car can cause the wheels to rotate, while engine in an aircraft can adjust the fins. The power supply is typically a rechargeable battery pack, but sometimes it is just normal batteries.

Many RC toys, radio controlled motor provides guidance, while other power supply provides locomotion. Here are some examples:

A plane model often has a small gasoline engine to turn the propeller; RC engine controls the flaps.

A sailboat uses the wind to propel; motor RC controls the rudder. Read more on
An airship used helium or hot air for lift; RC engines control small propellers.
