I rolled t' airframe with white printer paper, layered 3 thick, me bucko, taped them together, ya bilge rat, and rolled them into an airframe, put a spiralin' piece o' electrical tape t' hold it together while I glued t' ends. 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, t' simulate a reducer. Aye aye! 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. Ahoy! I kept t' electrical tape as decoration
