IMO the engine fit's right in between the complexity of real engines and the simplification of ksp engines (you don't need to model every single pipe and stuff because it would take ages and look complex when compared to other parts) and I also like it because it reminds me of NFLV engines
saturn INT-20 (basically S-1C + S-IVB) or saturn INT-21 (basically S-1C + S-II)
also, good luck in school, 2 weeks ago I managed to get to this exact threat from school
it seems to me atleast that the models of F1 and F1B merged into the engine you show here, I would recommend you to check if the dependencies of BDB are up to date
I like the similarities to *REDACTED*. Wait, is that *REDACTED* as a *REDACTED*?
after like 2 years I finally understand centaur-centaur, idk why it took so long
