Dave Snow in the Chicago Illinois area is a wonderful builder and designer. He designed a super lightweight built up wing kit for the Integral that was intended to replace the composite wing and be a significant improvement to an already good design. The replacement wing saved about 6 ounces (which in the pattern world is a ton), and allowed the builder (it's a built up wing) to slightly modify the wing tube alignment point (lower it or move it back an 1/8 of an inch or so) to eliminate almost all of the required mixing. I was competing with an Integral at the time so I ordered the wing kit. Long story short, I already had my integral flying great with all the mixing and such and never built the wing. It is still in its original box unopened. It is a classic pattern wing design in the 2 meter span and I think even an average builder can frame it up and have it covered in no time.
if you are interested in it, it's yours for a song. just pay shipping plus a few bucks for the effort and I will have it on its way to you.
PM me and let me know if you are interested.
