Those similarities being three centering rings with a 75mm motor mount, nose cone 21", diameter, electronics capable.

Although your real intent was a true 4X upscale I found it interesting that the Big Nuke extended with your fin design and a coupler could be built pretty close to your sustainer with currently available components. If I had seen your design before I built that kit it would have certainly have been a consideration to try that approach since the CD was always one of my favorites.

Actually your 4" Cherokee Double-J is the design size I like best.

So when did you say this kit would be available?

just kidding
