I spent a year tearing down and restoring a Mustang from the Cavenaugh Flight Museum (not alone mind you, along with 4 others). These are beautiful airplanes and I can tell you, that there are variants on top of variants. We had manuals, reference material, technical data out the rear to refer to and still had questions during the entire restoration period. Having said that. . . .is it possible that this is the most "overdone" aircraft in the Flight Sim world?
