Thanks for the thoughtful reply. What you are thinking all makes sense, but no spacers. The SFG's are definitely towed in. Take a look at the pictures, number 2 I think shows the angles. When you see my wing it is more obvious.

Well clearly the engineers for Great Planes did have something in mind. We will see. People so far says it is a terrific flyer. The tow in sure looks draggy to me though.
