Why not just figure the wing area out yourself? It's not tough! All you do is measure the length of the wing at the fuselage, then at the tip. Add these numbers together, and divide by 2. This gives you the average cord, or length of the wing. From there, all you do is multiply that by the wing span. Assuming both measurements are in inches, the result will give you the wing area in square inches.
