There are enough historical types that you could make a variety of selections available and have the players be able to fill in those or select color schemes for them. Just look at the art above here to see the various Squadron markings on these planes (B17 broad yellow stripe, 109 white nose, other B17 white square on tail with letter etc). These markings make a planes unit identifiable at a distance and a glance. Yes you would want it to not be naked dancing dragons on a tail, that would not be identifiable at a distance and would be silly ( or worse disgusting !). But either review of each submission or standard templates would allow this to be avoided. Just to clear up what I mean by templates, here are some examples of templates. Rudder and horizontal stabilizer is colored tail otherwise normal. Choose color. Or Horizontal colored band in middle of rudder and vertical stabilizer, choose color. Or Large Triangle with letter in middle of vertical stabilizer, choose color, letter and color of letter. Etc Etc Etc. Spinners would be simply a color and maybe variety of stripings (some schemes would be possible that did exist but were only detecable when engine off, such as spiral or quartering but this would serve no game purpose). Nose would be like tail, stripes, solid, or lettering on a shape. You could also have wingtip colorations or even symbols (such as the white arrow now on our Corsairs). Well I think that is pretty clear at this point, clear as mud heh.
