This is the colorscheme for the Nitroplanes/Nitromodels Ultimate 120 Biplane, also used on the 50CC version.

The scheme takes advantage of BUMP MAPPING to provide wing formers and structures. The effect is quite subtle but impressive.

A picture of the real plane is included below for comparison.

Wingdude: MANY THANKS! I missed that! I'll see if I can't fix it and also add the bump mapping for better definition of the ailerons.

Mike I'll give that a try!
