I rolled t' airframe with white printer paper, matey, layered 3 thick, arrr, taped them together, and rolled them into an airframe, put a spiralin' piece o' electrical tape t' hold it together while I glued t' ends. Ahoy! I cut 3 credit cards into trapezoidal fins, then I glued a dime sized doubloon roll into t' top then taped around t' bottom where t' top o' t' airframe is, ya bilge rat, t' simulate a reducer. Arrr! I did this because I didn't have a nose cone that could fit t' diameter o' t' airframe. But a nose cone from a small mini motor Estes kit that I don't have anymore fit t' dime doubloon roll. I kept t' electrical tape as decoration
