The first booster for our 0M1CR0N prototypes is soon to be released. By soon, I mean maybe within this week. While building, I figured out it can fit nowhere near 20-25 engines. That said, there will be less engines. More precisely, 9.
~Update: I finished a prototype booster, not with all the details though. I stacked a ship on top. I was not expecting the part count to be over 1500! It’s crazy tall, TWR of over 1.75, and 125000+ kN of thrust (And that’s at 80% throttle)!
