Pfalz friends in Work in Progress - Aircraft Posted January 24 Probably a bit late but I would probably do the same as Ian with the wings. I have one of these in the stash but it went back in the box when I built the Eastern Express kit instead. However, as an alternative I have cut the parts from the card and installed 10 thou card over the lower surfaces before filing the edges. In my case I then scored the ribs with a sharp craft knife. As Ian says sometimes you need a little thickness at the butt ends for guides.
