Wing load formula
Help me guys, I'm trying to figure out the wing load on my Ultimate Pitts. Do you convert the sq inches of wing area to sq feet then divide the total weight of the plane in ounces by the sq feet of the wing? If this is correct I'm coming up with a wing loading of 26.59 oz per sq ft. Doesn't this seem high? 192 oz (weight of plane in ounces) divided by 7.22 sq ft (1112 sq in of wing) = 26.59 oz per sq ft.

Math is incorrect. 1112 sq. in. -> 7.72 sq. ft. Thus, 24.86 oz./sq. ft. I'll mail you an invoice for my instant aircraft improvement service fee
By your wing area, I'm guessing your span is 50-60"-ish. If that's so, that wing loading is about right- should fly well.
