@BATTLEAXE, got something new for you to try and see if you like. When building a traditional ft wing with the creases in the airfoil, instead of just scoring the crease lines and opening them up with a skewer like you usually would, don’t score the lines and instead remove the paper a quarter inch on each side of the original crease line. Just score the paper when doing that. Then just compress the foam in that half inch wide area with your thumbs or roll it over the edge of the table. In the end, you have an airfoil that doesn’t have any score lines, which makes it stronger, and it’s a much smoother bend. Hope this makes sense! I’d like to see someone try it and hear their results!
