hey, loving the mod. or at least, mesbin. very unique. haven't gotten anywhere else yet.
i wrote a kOS script for generic ascent guidance. it's really basic. but i didn't find any other existing scripts designed for optimal *mostly constant altitude ascent on a massive airless body. and mechjeb just doesn't know what to do with it at all.
behold, 30 minutes of work and no prior experience in kOS.
behold, 3 hours of work and 2.5 hours of prior experience in kOS.
ships that are slow to respond to input could probably use another alternative PID setup once they get going, but it's not that big a deal. the acapello v did better than my manual run, anyway. well. maybe. the fuel masses at the start were a tiny bit different. bottom tank full is too heavy to takeoff. didn't check circulization dv the second video either. a rerun with equivalent starting fuel mass left it with 1990 in the first stage. humans officially outmoded.
