I've wondered about that myself. I don't see any reason dihedral wouldn't be effective, but I don't think I've ever seen it done.

I haven't either, that's why I am wondering. It seems to work when I made a paper wing, so I would think it should as well, but there is a big difference between a folded paper airplene and a real model.

Whulp.......I've always longed for this in a full-scale saddle 'em up version but though the borders on my insanity and imagination suggest that it stretches far and wide......I actually realize that this will likely never happen.

So I continue to dream it in an R/C version with an EDF.

If it were built as pictured with the pilot, it wouldn't be a speed machine (draggy?), but it'd look many shades of cool!!!



Whaddaya Think???

I've experimented with simple little gliders and large dihedral angles on swept wing tailless gliders does have a directional stability effect.. It works like a 'V' tail. I don't think it would work on a straight wing 'plank' type tailless model though, they need a vertical stabiliser.
