I've already stuck my neck out and estimated the effect on a 15 m glider
like mine. You can read that at www.oxaero.com, near the bottom of the page
on Dr. Sinha. In about a week I hope to have a good baseline polar for my
ship, then we will apply a full span treatment, inner panels first, and see
what we get.

You gotta spell things out for us slow kids in the back of the class. Is
the practical relevance that a 40:1 ship becomes a 40:.75? Are you moving
the polar curve, flattening it, both, other? Will it fit in a Christmas
stocking?
