    YES -- Very interesting indeed !

    Thanks for posting a reply, or based on past efforts , i
    would not have tried to open it !!

    Those D-tubes, and ribs, look a lot like my Exxtacy
    and the Atos .

    Wow! Bogdan Wozowicz sure made his wings a LOT lighter than the original BKB, which had heavy sitka spars and plywood skins, and a lot of heavy steel fittings and hardware to hold all that weight together. Did Bogdan retain the original 8-H-12 airfoil?

    =yes,"pure" /NACA8-H-12...(water cut).

    -it exist china PAEABEAM ,3 mm,but lighter as "auer", circa 0.5 kg/m^2...
    iff good proportion of epoxy/vinyl resin,it is possible to make much lighter wing.

    now we will try to modify EXXTACY wing into BKB1-A shape (1.22 m chord,NACA8-H-12
    airfoil,<30 kg weight).
