I love the air combat game Check Your 6! and have wanted to get much more into the war in the Pacific. Here are my Japanese and American air forces so far, in 1/600 scale by Oddzial Osmy and Tumbling Dice, and my flight stands.
I don't go too crazy with getting exact historical accuracy with rondels, tail markings, etc. I search around for ones I think look cool and then paint up pairs or 4's of aircraft accordingly.
Japanese fighters: Oscars, Zeroes, and Tonys
|P-40s and Cobras|
Kenney’s Killers: B-25s and Lightnings
Some nose art
Bombers galore: Dauntlesses, Vals, and Betty’s
1/600 planes are a breeze to paint. The flight stands are time consuming to make, but work well and are cheap (I can't remember the unit cost, but it is markedly lower than the commercial options).
