Actually................

That works great when there is no wing stagger. Remember the rule, "the pushrod should make a 90degree connection with the horn, with one line being the pushrod and the other going directly through the hingeline."

When we're connecting two hinged ailerons with one pushrod, we ought to be able to draw a line from the hingeline of one aileron to the hingeline of the other aileron. And that line ought to have two right angles in it. Or the two connected ailerons wind up with differential deflection.

The solution for both the Ultimate and the Skybolt required that the upper pushrod connection be above the top aileron. Because the top wing was significantly forward of the lower wing.

I had originally laid out the pieces for the Skybolt so the pushrod didn't run through the meat of the aileron. But since the easiest way to place the horn (and the strongest) is to slot the aileron anyway....... Less horn and glue = less weight. And I'm silly enough to count the grams. And placing the pushrod outboard the TE moved the connection points so far aft that the horns were appreciably larger, and I use the original hardware provided. I simply cut the T base off the horns provided and inlay the uprights. And they're only so large.
