Plane weight and its effects
Dave,
You seem to assume that I have an airplane that is NOT overweight.
Actually, my personal best time in QM40 was set with an airplane I later discovered was 7 ounces over. There may be something to that "more weight, less bouncing around in the wind" theory. But at most, that would reduce the amount of the handicap -- I can't see how it could possibly give you a net gain in speed. Otherwise you'd see the fast guys adding bricks.
