I've been wrestling with ways of doing a multiple piece wing. Std two piece center joined probably with the aluminum channel and bar insert. But have also been giving thought to a three piece.......flate center section with out board piece having 2 to 4 degrees dihedral. Struts at the joint The idea coming from the Flyin King and some glider designs. There's some pros and cons but the resultant polyhedral (?) is interesting. Your thoughts?
