I have been trying for couple of days to build launcher to my mun ship. I have Apollo inspired design. I have launched couple of different combinations. Below you see best attempt I can get and now I want some suggestions to design mun rocket that will actually go to mun. These flights have never exited atmosphere. I have already flown unmanned probe and unmanned rover to Mun so transfer burn will not be problem, only design.
