Here's a idea that I had Biber...

With the quest to have more wing in the middle (to have more effective elevator) I have tried to make the L.E. of the wing concave instead of convex. This also helps the wing lines contour into the puller fuselage. If you look at the middle pictures...on the left is 'your' wing design, on the right is this proposed wing shape. The yellow shape on the right is a mirror of the left and shows the similar area between the two wings. To explain further...the wing on the right has more in the middle, but that is ballanced with less at the L.E. This has been done to get more elevator, but not increase too much the wing area in front of the C.G. or N.P.

What do you think of my logic?
Does this 'new' L.E. worse for drag?
Have you 'been here' before and not gone this way for certain reasons?

Two pics for you Biber...I guess that the problem with elongating the mid if the wing adds more wing in front of the C.G. which counter acts the amount of wing behind that point...
