That sounds like a very prudent plan. I'm impressed you are building your own VAB

Coop,
Thanks for your reply. We’ve discussed this a lot since December. Plan now is to keep it 3,300 feet (1 kilometer) altitude and spill the laundry on top. Decision is driven by the potential forces at mains deployment after free fall.
To achieve that flight we are considering a dual thrust motor. There are several reasons to favor that profile. We want 5:1 thrust to weight at lift off. We want to throttle down for altitude target. We may also operate higher pressure early in the burn where case temperatures are lower.
I visited the construction facility this afternoon. It’s looking really good. Open area is about 50 x 90 feet. Electricians are almost done. Place is freshly painted. Many machine tools have arrived awaiting installation. We should have access about 15 May.
