I've been doing a lot of research on both Pattern and IMAC designs, and in comparing notes, find 3 basic arrangements, on planes with typical Pattern dimensions...

The most popular one seems to be to have the wing about one inch below the thrust line, with the stab on the thrust line. The second most popular seems to be to have both the wing and stab on the same line, but slightly below the thrust line. The third most popular seems to be to have the wing and stab on the same line, right on the thrust line.

I'm hoping that someone here (Ollie or Paul?) may be able to shed some light on why this is so, and benefits/drawbacks of each.

THANKS!
