Hello! I'm a new KSP player. I've played the demo and then bought the game a few days ago. In career mode I did my first Mun landing (and return ), but I was frustrated by not having a record of my flights. That's why today I started a new career along with a website for my SpaceCars Aerospace Space Program. It is still a bit messy, but I hope it will give some of you a nice nostalgia for when you still was a clueless beginner. Now, onto my newbie question! I wanted to calculate the max payload to LKO (75km) for my newly designed lifter. How do I do this? I'm using the Kerbal engineer mod, so I know the Delta-V, TWR, I_sp, etc. I should be able to derive max payload from those right?
