An airfoil doesn't have to look like you normally expect in order to create lift and have good flying characteristics.

Check out the pictures here:

Now we aren't flying at those speeds, but the fact is, the DIFFERENCE is what makes your wing lift. The shape of the difference is what determines the lifting properties.

It's obvious how the ribs fit the spars, but in the drawings of the wing ribs, is the wing bottom on top, or is the thicker section supposed to be on the bottom as it is drawn? Does the wing have anhedral, or dihedral? How can you tell if it's right side up, or upside down? If the wing ribs are right side up, it will be the first model I've ever seen to do that.

I hope we can all agree on this, as it obviously matters a great deal.
