Mike,

I did some digging for info on high lift but did not come up with much, too technical where I was looking.

What intrigues me is the research going on with Low Reynolds numbers wind tunnel testing. Drela and most are going to thin sections. Is this just for speed? don't know.

. I read something about "articulated control surfaces" and Thinner sections that perform better than Scaled down control surfaces. The analogy was made that if an airliner flys through a sea of ping pong balls, a model flys though a sea of Basketballs. What I gathered was that a lot of the wetted areas of 'full size' don't scale down. Thinner is better, slots maybe should be wider, slats thinner. The air doesn't scale down, it's thick and gooey at small scales.
