Glider flight controls. How does the control stick make the ailerons work? (And what about those flaperons?)

The video is in three sections. (Sorry about the abrupt jump cut edits.) First section shows the control stick moved side-to-side to move the ailerons. That motion is carried by various push-pull tubes and bellcranks...aft of the landing gear. In the second section of the video we see the lever for one wing goes up while the other goes down.

But I have flaperons, not ailerons. The third section shows the result of moving the flap lever...the same wing control levers now move up together, or down together.

The mechanical mixer allows two different control inputs (control stick sideways motion, and flap lever) to be combined into one final motion.

Glider flight controls!

This is only part of the entire system. It is one of the more complex parts. This portion of the system changes camber of the wing flaperons. Please read the alt-text for more details.

One important part of this subsystem is the use of a push-pull cable, which is rather different from the cables you typically find on bicycles. (See the first comment to this post for a photo of the push-pull cable.)

I will post other videos that show other portions of the mechanical flight controls.
