Astrobee1500 fin-unit for ST-20 tube for 24mm motr

This model and my other parts that I offer associated with this subject, are based on first hand manfacturer design data from Aerojet Inc. This fin unit also has the canted fin angle as per the actual mission flights, for realistic boost spin revolution. See my recruit motors, and clam shell nose cone to complete the project. All that is required to complete the airframe is an 11.5" body of 2.05" standard diameter ST-20 tube( centuri/semroc ). This fin unit is for 24mm motor mount.
