The Swash Plate Assembly

The swash plate assembly fits on to the main rotor shaft beneath the head of the heli and consists of one rotating and one non-rotating disc.


The swash place on an RC helicopter is used to translate the pilots commands into the motion of the main rotor blades. The lower, non-rotating disc is linked directly to the cyclic and collective controls which are controlled by servos under the command of the pilot's transmitter inputs.


This non-rotating disc is attached by a bearing to the second rotating disc, which turns with rotor and is linked to the main rotor blade pitch horns.The swash plate can be made to tilt in any direction according to the cyclic controls, or move up and down to change the pitch of the rotors under the collective control, which allows the pilot to control the RC helicopter in a 3-dimensional space.
