I've been mucking around myself with some icons lately, and I thought I'd share them with you guys. These are game size for now, but I might go back and post larger pictures when I have time.
O-2 "Sleepytime FAC" (note the writing on its wings was inspired by an actual picture; its reads "THE FAC")
B-26K (COIN Green scheme)
B-26K (3-Tone/SEA scheme)
All three are hacks of stock SPMBT models, with the B-26Ks taking parts from the A-1 Skyraider (stores) and the Fouga Magister (wingtip tanks) icons.
