My 5.5″ (1/13th scale) Polecat Aerospace Mercury Redstone. It was built by my father and I in 2007, and I rediscovered it, sitting alone and sad in our shed in December 2012.
It features scale fins, electronics bay, a separate parachute + bridle for the capsule, and a 54mm motor mount. The preferred motor is an Aerotech J180T, since the flame color and takeoff speed is almost incidental to the real thing.
Upon moving houses in June 2013, I found the pieces we had picked out to make the escape tower for the Redstone. I then proceeded to finish the escape tower assembly.
It currently sits in the workshop, ready to fly.
