As we all know that children love to fly remote control devices such as helicopter, boat, planes etc. Remote control devices have changed the way of playing for the children. So let us understand their mechanism of flying. RC PLANE :- RC planes fly due to torque created by the propellers attached to the motor.Generally brushless motor is used as it produces more torque/v. Basic RC planes have elevator named part that controls the altitude of plane at which the user wants to fly. Basic RC planes have ailerons named part that decides the direction of plane. RC HELICOPTER:- RC helicopter also have the same principle of flying as by planes.These also uses brushless motor to create flying torque for the helicopter. But the direction are not mandatory as the plane because in helicopter pitch and direction are maintained by 'SWASH PLATE'. Swash plate is consists of two plates connected horizontally with ball bearings in the middle gap. The main part for controlling the pitch and direction is 'SERVO' motor. Servo motor changes the swash plate according to the information received from the transmitter and hence the helicopter moves to that pitch or to that direction.
