Fantastic modeling! I do have a question about the manual, however. I'm trying to figure out the mechjeb profile for the shuttle ascent, but the described parameters either don't exist in mechjeb, or more likely, I am unfamiliar with them. For example, I am not aware of any setting that allows you to establish an orbit without coasting, or even an eccentric orbit for that matter (without extra maneuvers). Additionally, which setting relates to pitch rate? Would it be possible to send a screenshot of the proper mechjeb settings? Finally, whenever I try using my mechjeb profile, the SRBs end up just destroying the orange fuel tank because the boosters separate while the shuttle is rolled on its back during the ascent.
