I have used "Aircraft Colors" RLM 70, 71, 65, and 04, with really good results.
They spray perfectly righ tout of the bottle through my airbrush.
Nice to know that Pix thinks the 04 yellow is an accurate color. I spray mine over Floquil's flat Reefer White (a railroad color, which is excellent in it's own right).
I think the greens are a bit too light, though, as they come "toned down" for scale effect. I really like the 65 Lichtblau (light blue). It will spray right over the greens with no problem.
Here is a picture of my Dornier using all of those colors.
I think you can't go wrong with them, but next time I will darken them with a bit of black, which I think will look better.
Hope this helps
