This model was created as training materials explaining operation of the main rotor of Fully Articulated Type Main Rotor Head created previously.
There are many different method of actual helicopter’s control.
And the hydraulic system, servo, and computer are used and the control equipment is also complicated.
Here, two control levers such as "Collective Pitch Stick" and "Cyclic Feathering Stick" were reproduced with all of the mechanical link and the lever.
The quantitive relation of the operating angle of sticks and the pitch of a rotor blades is not verified.
