@Marcus: Just the original Crimson Skies rules.
@Arlequin: I'm building John Pattersons designs in 1/200 in 1/72 and I'm trying to stay as close to the originals as possible. Giving these winglets is already a big change, and in the future I wan't to copy more of his work. The only problem bits are the cockpits as he liked them fancy and I am limited by what the kits give me as I want it all to be easy to replicate in the future, if I need more.
@Michi: thx.
