RE: Balsa USA 1/4 Sopwith Pup build
Maybe someone can help me here, I am buiding the 1/6 pup and ran into a snag, the die cut false ribs are considerably smaller than the full length ribs, what I mean is that with the wing on the building board the ribs touch the plans and the false ribs dont , also they are smaller all the way around, these are called 1/16 ribs, there are some false ribs that are exactly the same size but are used else where, any ideas be would helpful. thanks ...dan
