RC electronics have three necessory elements. The transmitter is the controller. Transmitter is consist of control stick, trigger, switch, and dial at player's finger tips. Receiver is assembled at model side. It reads and translate signal from transmitter side that sent to servo and speed controller (ESC). servo numbers in the model decides channel numbers that radio must provide.

Generally transmitter multiplexes and modulates signal into pulse, receiver demodulates and demultiplexes signal and turn it to special pulse width modulation which is used by standard servos and controllers.

Radio-controlled aircraft (also called RC aircraft) are small aircraft which will be controlled remotely. There are many types, range from micro park flyer to large jet and medium aerobatic model. Aircraft uses various ways of propulsion, from brushed or brushless electric motor, to combustion engine, to the foremost expensive gas turbine. 

Radio controlled helicopter, although often grouped with RC aircraft, are unique due to the differences in construction, aerodynamics and flight training.

A radio controlled car may be a powerful model car driven for a distance. Gas, nitro-methanol and electric cars exist, designed to be ran on and off road. "Gas" cars traditionally use petrol, though many hobbyists run 'nitro' cars, employing a mixture of methanol and nitromethane, to urge their power.

Radio controlled boat is a model which is controlled by radio controlled device, popular boats are scale models range from 30cm to 365cm, sailboat and power boat. The latter is more popular among toy grade models. Out of radio controlled model boat sprang up a replacement model: gas powered boat

Electric power is usually the chosen sort of power for aircraft, cars and boats. especially aircraft has become more and more popular nowadays, thanks to the recognition of park flyers and development of technology like brushless motor, brushless speed controller and lipo battery. These allow electric motors to supply far more power rivaling that of fuel-powered engines. it's also relatively simple to extend the torque of an electrical motor at the expense of speed, while it's much less common to try to to so with a fuel engine, perhaps thanks to its roughness. this allows more efficient and larger propellers be used to offer more thrust at lower air speeds.Most remote controlled models use handheld device with antennas that transmit signals to vehicle's receiver. There are two different sticks. On the left is a stick with altitude vary of flying vehicle or move vehicle forward or backword. Sometimes in flying model the stick stays wherever the finger place it since underneath may be spring caused to maneuver back to the neutral position once released by finger. Generally, for ground vehicles, neutral position of left stick is within the centre. the proper stick is to move flying vehicle around in the air in some directions and for ground vehicles it's for steering. On the controller there is a trimmer setting which helps keep the vehicle focused on single direction.

Phone and tablet control:

With the influence of touch screen devices mostly phones and tablets many RC vehicles are often controlled from any Apple or Android devices. On the OS store is an app specifically for that specific RC model. The controls are almost just like those on a physically used remote when using virtual remote but sometimes can vary from an actual controller counting on the sort of auto . The device isn't included with the vehicle set but the box does accompany an radio chip to insert into the headset slot of any smartphone or tablet
