Well that's kind of a sad thing to me. I am trying to build heavy SSTO spacecraft capable of some resources or another spacecraft delivery to orbit atm and it is really hard task. So I hoped maybe your design might uncover some clues I haven't been aware of. I was wondering that maybe my ascent profile is wrong (well getting pretty high and gain speed on horizontal flight is no big science to be honest, but still). I will wait for fixed craft. The ship is a beauty
