As I mentioned before, the Hiller control system is used in my design. All the cyclic controls are transmitted to the flybar directly.

There is a metal bar ironed perpendicularly to the flybar. It holds the metal ball of the ball link in position. Here is how the ball link is made:

         

The rob ends are shortened and a metal bar is used to connected them together. the metal bar should be inserted deep into the rob ends and fixed with epoxy adhesive.

In addition to the ball link, an "H" shaped anti-rotating unit is a must for the control system. It helps to keep the ball link in position. The materials needed are showed in the above photo.

In order to stop the lower part of the swashplate from moving, an anti-rotation unit is also needed here. It is simple a small board with two pins inserted on it.
