I was looking for a unique way to show the effects of drag to students in the rocketry unit besides using the conventional parachute or streamer. Inspired by seeds falling out of a maple tree ( Watching them rotate their way slowly down towards my gutters) I though why not helicopter blades. Did some research, saw some good ideas, and this is what I came up with. The rocket will accept ESTES model rocket engines A,B,and C. I'm happy with the looks but think its could be lighter.
