Daron,
Congrats on the continued development, but I don't know why you want to make a
biplane, except for kicks.
The most efficient wing, from a drag reducing perspective, is a long thing one
(think gliders, and MacReady's man powered planes). Short stubby biplanes wings
have a lot of drag, and the only reason biplanes existed were because materials
and design weren't advanced enough in the early days of aviation to make safe,
strong monoplanes.
Thanks,
George
