GA aircraft aren't pointy because they have a prop. Look at a pusher prop. Like a Long EZ. I've been putting this on the back burner until I can get you guys hard evidence to prove my point... I've got a friend doing some testing on spheres with planed front ends (modeled after the cameras on heli's). Its neat watching the stagnation build. If I can find a way to get the videos to you guys I'll send it. It just seems important to remember that your drag is the difference in pressures... Decreasing frontal pressure and increasing rear pressure is the whole point of this.
