Ok. Steve/Jetsett44 has explained this many times in his parkjet threads in the pusher jet sections. A search there may yeild more spesific results. But a flat plate is just a very thin airfoil. There is no part of it which you can say that makes it not. By sanding the front of the LE round you smoothen the airflow and decrese drag and get a slight airfoil effect. And even if you dont sand it its still an airfoil. Its just at the sizes "we" build the effects arnt too noticeable to make any diffrence. but the time it takes to build it goes up alot with a standard rib wing when compared to a flat one. and its also a lot easier to repair
