I have one of their sets 72.21 USS Forrestal Air Wing 6 in 1/72.
Looks great, well in register, but I haven't tried applying them yet, as the project they were intended for is on the back burner (VAW122 E-2C).
Not much in the way of stencils or national insignia, just a/c specific markings.
Personally I'd give them a thumbs up if it's an obscure subject you're after.
