My First 5 designs. Would love hear some tips to make the next 5 better. I'm looking for advise on how to make really REALLY BIG SSTO's able to get to laythe without re-fueling, I've seen it done on youtube but haven't been unable to replicate yet mainly due to things like; sudden combustion, floppy wings and of course fuel depletion issues . ... Sorry I han't taken orbit pic for all .. what can I say , I'm lazy but trust me they all get there
