Cyclic Control

As the pitch angle changes, the lift generated by each blade changes and this unbalanced lift causes the helicopter to tip towards whichever side is experiencing the least amount of lift.The cyclic control works by tilting the swash plate up or down and increasing the pitch angle of a rotor blade individually as they revolve, so the angle of attack on one side of the rc helicopter is greater than it is on the other.


This allows the helicopter to move in any direction around a 360-degree circle, including forwards, backwards, left and right or any combination of the 4.


For example, when the cyclic control is pushed forwards on your radio transmitter, the swash plate tilts forwards increasing the angle of attack (and lift) in the rear of your helicopter which causes it to move forwards. Your radio transmitter handles all the mixes and translations between cyclic and collective movement, so all you need to think about is which way you want your helicopter to fly, not angles of attack or swash plate tilting.Because of the cyclic and collective pitch control of the main rotor blades and the pitch control of the tail rotor, your engine RPM and therefore the speed of the main rotor blades, can be kept at a constant rate increasing maneuverability response time.
