Hey guys. I am thinking about building some bases and the most efficient trasport of parts and cargo is a cargo ssto. I've tryed to make one but it had a ton of problems (was too heavy, lift problems etc.) So I turn to the forum for help. Can you help build me (or have me build, whatever you want) a cargo ssto. I have a few requirements: 1. Must have a opening back so when I land I can unload/load cargo 2. Must carry a good amount of cargo (a couple of rovers, some supplies, base stuff etc.) 3. Must use both rocket and jet engines (for both space and planets with atmosphere and without). Let me know about what you made or how i can make it
