.This is absolutely nuts, comparing the flight of a golf ball to an airplane is like comparing the weight of a bowling ball to a ballon. The airplane with a laminar flow airfoil on the wing is the lowest drag you can get and is the fastests, but to get laminar flow the surface must be very smooth and free of waves even fly specks will trip the flow at high Reynolds numbers above 15 million and bugs also will. the Reynolds numbers on the KR-2 and most general aviation aircraft is in the range from 2 million to about 4 million which is the real key to this anology of the golf ball and the KR-2 the Reynolds number for the golf ball is about 100 and the reason the drag is lower for the golf ball with the dents in it is the flow becoms turbulent and reduces the seperation drag because below a Reynolds number of 400,000 the drag of a laminar flow airfoil is higher than turbulent flow and so it is with the golf ball, the Reynolds number is much less than 400,000. ITS THE REYNOLDS NUMBER.
