This is my first Mid-Power rocket project: An Estes Scion modified into a sport scale Patriot Missile. The Scion includes the fins and nose cone from the Leviathan, so the conversion can be done from a Leviathan as well. Plans available at www.rocketryforum.com . I built this kit using high power techniques (internal and external epoxy fillets, kevlar shock cord attached to an eye bolt, rail buttons, etc) for practice for a bigger project, and to withstand a high power certification attempt on an H128 motor. I had a ton of fun with this project and learned a lot! Maiden flight was with the Washington Aerospace Club on 4/17/16 at 60 Acres Park in Redmond, WA.
