posted pic on brag forum, used mach 3 blade for thin section of glider wing and two cuts with 2/0 for the wider part, but was getting drift towards the first line - should have stuck with thicker blade. in some places I started with a straight blade and then used Mike's new spiral blade, 2/0
got another pic in mind, this time more close up on glider landing - more blue air on way
