Simple Perfect Tandem Rotor Swashplate (Vanilla)

Block count: 135

This is a tandem rotor swashplate. You can use this design to build your own tandem rotor. I have done all the work for you. This design is a workable helicopter. However, if you are inexperienced with realistic helicopters, I recommend that you start out with a coaxial or transverse rotor configuration as they don't suffer from dissymmetry of lift.

Swashplates are used to controls the movements of helicopters. There are many different ways of building them. Many of these designs, however, are either very block heavy or unable to handle long rotor blades and only very few of them feature collective pitch.

This swashplate design has none of these drawbacks. The mechanisms are based on how a real life swashplate works. The design is the result of many, many hours of research into how a real life swashplate works and what works best in besiege. It is the basis of all my helicopter designs.

The block count is only 46.

Features:

Pitch: Pitch makes the nose of the helicopter go up and down. On a tandem rotor, pitch is achieved by differential collective control.

Roll: Roll makes the helicopter roll from side to side.

Yaw: Yaw rotates the helicopter. In a tandem rotor yaw is achieved by differential cyclic. On one of the rotor, the swashplate tilts left and on the other it tilts right thus and vice versa.

Adjustable collective: (Steering hinges are used for this mechanism. They are the best choice since it is possible to limit their angles) Collective makes the helicopter go up and down.


How a swashplate works:

A swashplate consists of a lower and an upper part. The lower part is attached to the fuselage. It consists of the the pistons. The upper part moves together with the rotor. The lower part transmits movement to the upper part which then can change the pitch of each rotor blade as the blades moves around.
