Radio Control Toys and Remote Control Models Wholesale
Radio control (often abbreviated to R/C or simply RC) is the use of radio signals to remotely control a device. The term is used frequently to refer to the control of toys model vehicles from a hand-held radio transmitter. Industrial, military, and scientific research organizations make use of radio-controlled vehicles as well.
Radio control is a way of making models of cars, helicopters, boats, tanks and aircrafts move on their own like real ones.
Invisible electrical signals called radio waves come out of a part called a transmitter. The transmitter is a box with the model's controls on it. When a control is moved, the radio signals changes. The part on the model that takes the changing signals and helps turn them into movement is called the receiver. The receiver then tells a special kind of motor called a servo to move part of the model. On a car or boat, a servo is usually used for steering. Model sailboats use a servo to adjust the sail as well as the rudder, or steering device. On airplanes and helicopters, servos are used not only for steering but for up and down pitch. If the model uses an engine to make it run, a servo is used to control the speed of the engine. A model which operates with an electric motor usually has something called an electronic speed control or "ESC" to control its speed.
