Sorry about bad title. So I have been playing for quite a while now and I understand how TWR works. Each stage will have to have 1.0+ for my calculated TWR in or for me to get any lift. I have that much down. My question is. How do I know if I have enough fuel to get me all the way to orbit. I could easily overcompensate and just put everything on a heavy launch system, but that is too easy and I would like to be "economical" about how I build things and not end up in space with 2k extra fuel. I'm sure you all understand. Is there a calculation or anything that I need to know or something within mechjeb that I can use to tell me if I will just flat out have enough fuel to get me all the way to a 100k orbit around Kerbin? Thanks for the help in advance everyone!
