The purpose of this project is to fly a two stage model with a loud and smokey D motor booster on a small field, yet limit the altitude to a modest height. Since ringtails are known to be draggy and/or inefficient compared to conventional fins, these will be ideal for this purpose.
Raw materials, tools, and semi-finished components laid out. Tube is BT-60, support fins are 1/8" balsa, rings are 3" PETG shipping tube cut down to 1.3". Length is projected at 28". The finish is planned to be a lurid pink, purple and lime green.
