A semi scratch build rocket I call silver surfer. I used to Estes  airframes that I coupled together 2 bt-80 body tubes, used a 24mm 18 inch tube I found in a take what you need bin at a local launch. Cut the centering rignus, cut and motor half an inch thick and used that as an engine block, took an engine hook from a Non repairable kit that crashed, the nose cone was given too me by someone at a launch, then I bough some sheets of eighth inch balsa, and decided to use the big Bertha fin shape because they add a lot of stability and drag to the rocket because I wanted a slow and realistic flying rocket. it flies a little bit tilted to the left, but not bad, the trajectory is always straight. It flies too about 500 feet on D's, I'm going to remove the engine hook and install a motor retainer so I can do composite Es and even some 24mm Fs. One of my favorites in my fleet.
