The instructions indeed say black and olive green (or completely green) I have the same kit as in Ed's link. I was just wondering how the 'black' looked in reality on the real Buffalo there. Using black (or any dark color, like olive drab or German grey for that matter) on scale models usually looks too dark as on real life large surfaces, dark colors tend to look lighter.
So I would have to opt for either very dark grey, black-green or black with a thin filter sprayed over it or something.
I'll try the Buffalo first, as it was cheaper. If I mess up with the black, I can always decide to make the Fokker just green :)
Thanks anyway for the nice links
