I decided I wanted to build a vessel in space. It was going to be fairly large. I built it with the Large docking ports, but when I turned on the engines after 2 days of assembly and prep.....
It started bending and flexing etc. It was so unstable, I had to send undock all the parts, stabilize the command modules, and send a rescue ship to get all 3 kerbals that I was sending. They were quite upset with me.
Im on the Xbox, so no mods. Is there a better way to build a vessel in space that is stable?
