RE: FS One by Hangar 9
That looks really nice.
I tried that a little a year ago. I'm not artistic though. I removed the forward swooping swirls from the wings of the ShowTime so that everything was sweeping back only. And I changed the Skylane scheme to look more like the 40 size Great Planes ARF of the Skylane.
To do a good job takes some skill and proper software, but the paint schemes are otherwise easily accessable in FSOne.
