RE: Vne discovered (Electric Flying Wing)
I hear you about tapering the airfoil being a chore...
I done it with smaller spans as well as large spans with a much thicker airfoil. With a thicker airfoil you just down size the ribs as you move out to the wingtip, making the ribs is simple were you only need the root and tip patterns like cutting a foam core and sandwich a stack of balsa blanks between the patterns and shape all the ribs together. When you are dealing with a larger thicker wing it is not all that big of a deal, but all of this does not easy to implement when you are dealing with a airfoil as thin as yours.
The three basswood ribs should make a big difference as far as the front to back rigidity.
