The rocket is an upscaled version of the Estes Viking. I went from the original BT-20 to a BT-60 tube, the body itself is 19.5 inches and is recycled from the top of a Mean Machine that had a boo-boo on launch. The fins are 1/8" basswood filleted with epoxy and the nosecone is a Semroc BNC-60G4.

The motor mount is 24mm with a screw top retainer. I added a thrust ring into the tube so I can fly it with my 24/40 reloads or Estes BP motors.
