I agree with your idea of less fuselage area, da Rock. However, my Taube is definately NOT a fast airplane. It might do 45 downwind! There is very little side area on the fuselage which keeps it from being bothered by the wind, both in the air and on the ground. However, it has a lot of wing area (Hint-empty space=less dense.) Any good light plane will fly better than the same plane that weighs more, even in the wind. If you don't believe me, let me put an anvil on your plane and let's see how much better it flies in the wind.
