RE: 1/3 Scale Balsa USA Fokker D.VII Build
Another thing to look out for is relatively minor, but would have definitely tripped me up. The instructions want you to use a 3/32x3x15 piece of sheet balsa to sheet the area between the root and neighboring rib. The only reason I didn't goof up was because the sheet was too short to span the distance from spar to the trailing edge. Had it been long enough, I would have glued it in with the wood grain in the wrong direction. The instructions should clarify the need to cut the 15 inch sheet into several smaller cross-grain (correct term?) pieces.
