Product Description
This is Redstone Booster fin unit is sized for the Mercury Redstone that is re-ssued by Estes again (kit #1921), and for matching the Jupiter-C nose cone sets from Moldin' Oldies that are still available. It is based on the Centuri ST-20 body tube, still widely available through BMS, Totally Tubular, and Semroc (now eRockets). My new larger fin units will be minimal outer shells to take advantage of the new pricing structure, significantly lowering the costs. This unit is a hollow shell with a bearing flange for the motor tube at the exhaust end, and all you need is a long stuffer tube design with two ST-20 rings ( maybe from the kit ) in the main body tube for support. Use a simple BT-20-to-50 adapter ring or Mylar retaining band for the hook retention if one is used. Enjoy! Also see my Mercury Capsule Set for added realism using this Fin Unit, and go beyond the Estes kit.
