RE: Making Balsa USA Eindecker 40 more scale?
I'd keep it fun scale and be careful about mods that will end up adding too much weight or affecting balance. I'll 2nd the suggestion to build the fuselage sides with longerons and diagonals instead of the slab walls. I wish I'd done that on my Eindecker 90. Covering it with solartex and using scale fittings will dress it up nicely.
