I see, thank you very much!
It is definetly more realistic than I thought, which is only a good thing
EDIT: Nope, still does not work, I get the apoapsis to about 40-60km on the last stage of the carrier rocket, I cant even reach it because apoapsis starts to come down again even though I keep accelerating on full throttle. There has to be something Im doing wrong here, my progress weighs about 6.8 tons, so it should be okay? I just cant get to orbit, mechjeb altitude was set at 160km, AoA limiter was on and the flightpath set at 55%. Im running out of options here.
