    Subject: Re: Airfoil Drag Video
    I am far from an aero expert, but I found the video interesting. I did not grasp the inference that a round shape has more drag than a rectangular one. Rather I understood that a streamlined shape has less drag than a round one. I guess it was made for laymen like me. Stan Sutterfield Not repeatable therefore not real useful for comparison. The guy should rotate the airfoils to minimum drag each time, otherwise, he doesn't know if they are in comparable positions. It's also a shame he didn't replace the airfoil with an equal-flow-area rectangular shape. As a result he produces confusing and misleading results, inferring that a round shape has more drag than a rectangular shape!
