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