I figured it was for doing neat stuff at a real low speed. The position of the ailerons....as far back as they are anyway.

Looking at the close up of the first image - at the midpoint between the trailing edge and the leading edge of the aileron, it looked like there was something else. Thats what I was trying to figure out. That was before anyone posted a reply. By the time I finished mine, all the answers were there. I see it clearly in the under wing picture now. It's a pushrod. It looked like (in my imagination) that there were rods at each end connected to what could have been bellcranks. This could have positioned the entire assembly for and aft....in my (imagination.)

So, whats the coolest thing this does?
