I'm having real trouble getting a launch vehicle out of atmo. All my attempts to structurally stabilise the different stages meet disaster. I like KW Rocketry mod and try to use the 3.75m sections where possible (want a manned return mission to the Mun). My staging must be snafu.I will persevere, but it's becoming tougher the more time I invest in it.
