Oh yeah, that first attached picture above isn't a depiction of either the Skybolt or the Ultimate. I made it up just to show what the ideal right angled rigging would need to be. The green dotted line would be a rigging that has a right angle for the top aileron and a right angle for the bottom. And the discussion was about linking ailerons at the TE. Which also works pretty good.

The point of the right angles on the green lines would be where you'd want the horns to connect to the pushrod.

To tell you the truth, I'm completely baffled why a manufacturer would do what they did with the Skybolt and little Ultimates. Eventhough it's been done by others, it's never been done on purpose for larger biplane models, and for a pretty good reason. Have you ever seen a big bipe, or any bipe with individually driven ailerons where the mfg wanted you to adjust the upper servos to give such wierd deflections?
