What are Radio Controlled Airplanes and Helicopters?
Radio controlled airplanes and helicopters are aircraft models that are controlled with the help of radio signals. The controls are generally sent via the hand held transmitter that has a joystick operator and the airplane or the helicopter has the receptors that catch these signals and operate accordingly. The receptors operate via servomechanism which is an automatic device that enables movement of control surfaces according to movement of the joystick on the transmitter. History of Radio Controlled Airplanes and Helicopters Radio controlled Airplanes and Helicopters have been a major hobby since several years. This unique hobby dates back to the late 19th century, which boasts of electronically guided, hydrogen filled airships. These airships were flown as a music hall act around theater auditoriums using a basic spark-emitted radio signal. In was in the 1920s, that the Royal Aircraft Establishment of Britain built and tested the Larynx, which was a monoplane with a 100-mile range.
