Let's Goooooo!
Got really interested in Jim Jarvis' Vertical Orientation System (VOS2) described here: (https://www.rocketryforum.com/threads/i-could-use-just-a-little-guidance.122042/). After a bit of back and forth with @JimJarvis50, I bought his last unit of the current run of the VOS2 system. BTW, Jim is one cool dude and I'm appreciative of his time and contributions to the hobby. Cheers Jim!
I've followed Jim a while. I have agreed with A LOT of his design precepts, sometimes only on intuition. Zipperless design, internal avbay, large fillets for T2T etc. etc....
Design objectives (5, 6, 7 and 8 are Jim Jarvis designs):
Here is "Version 3" of the design.

Design objectives (5, 6, 7 and 8 are Jim Jarvis designs):
- VOS2 integration.
- 2000-7000' launches. (I'm in Ohio).
- J-K motors (54 and 75mm, limited to 54/1706 and 75/2560 cases).
- DD.
- Zipperless design.
- Internal Avbay (no tube break).
- Piston Ejection on the main (you'll see why later).
- Adjustable fins to maintain stability.
- Motor retention without thrust plate or retainer.
- I'm sure there are others I'm not thinking about.
