dale,
Don't worry about your wing loading, you can get away with 50 or more oz/sqft on a bird of that size. I am flying a T/F Mustang that is 84"w/s and has a wing loading of 41oz. Flys like a puppy. Actually almost too lite in a strong wind. I can land without flaps with no problems. I did a 110" B-24 that was only 52oz wing loading and it flew very lite as well.
Check with some of the guys in the warbird forum about what kind of wing loading they have on their "Big" birds. I think you will be suprised.
