Looking very hard at those pictures, there doesn't appear to be a saddle for the wing to tuck it's diamond airfoil into. The profile of that wing is what's called a diamond airfoil. And for it to sit properly on the drainpipe fuselage, there should be some kind of structure on the bottom-center of the wing, or on the fuselage. There isn't anything on the fuselage in the pictures. And from what the pictures show of the wing, if there is a special structure under it, it doesn't extend to the LE of the wing for sure.

When you strap on that wing, how does it orient itself to the fuselage?

Does the bottom-center of the wing look just like the top-center of it? Is there nothing extra under there?
