I would truly like to research and make aircraft skins.  Unfortunately I have no idea where to start.  I've been modeling aircraft and collecting prints and models for over 50 years.  I also have many many plates of actual WWII Aircraft and Volumes of books on the subject.  I do have Flying Colors from my airbrush days....but now it appears there are better sources for information.
What software would I need to start?
What are reputable online resource sites? (Colors, Insignias etc.)
Any help would be appreciated!
Thank You

Oh BTW!  I have a scanner and fax machine so I can send plates over the internet.
