Gemini-Titan 1:46
A scale Gemini Titan had been on my wish list for a while. This is the builder's kit from Boyce Aerospace Hobbies. The kit comes with some very detailed 3D-printed parts that you combine with standard Estes body tubes, parachutes, shock cords, etc. The motors are retained by 3D-printed screw-on retainers made to look like the engine bells on the real vehicle. The kit also comes with self-adhesive wraps for the body tubes; these are very difficult to get aligned exactly right. My build is not that detailed and far from perfect.
I have flown it once; on that flight, one of the shock cords broke and the forward section dropped without a parachute. The only damage was a minor crack in the coupler and separation of the forward body tube from the 3D-printed center section. I have re-glued the separated part and replaced both shock cords with heavier ones. I plan to fly this rocket again in April 2023.
