So, I just found out that the former SimpleRockets 2 got a huge update, so of course I wanted to try it out. I have quite a few hours in the game, but not nearly as much as the high hundreds to low thousands in Simpleplanes or KSP. I'd really like to build a proper SSTO, but i couldnt find any scramjet engine, and from what I've learned from KSP (I know its not the same as SimpleRockets 2, but its the only space themed sandbox I've played for a significant time), those are essential for not half bad SSTO's. If there isnt any, how can I simulate one efficiently? Thanks in advance.
I suggest something long and narrow
