Hmmm... not sure, the Endurance is designed with pistons to extend and retract to dock with the Atlas, I'm planning an update utilising some of the new DLC blocks, so I'll take a look at this when I have a chance.

I really enjoy the build, it is very cool! However, I pasted it in creative just to take a look and for some reason it has no dampeners and the Atlas units won't detach without ripping the whole ship apart. I tried spawning the Endurance and Atlas in separately but the Atlas blueprint doesn't seem to be wide enough to fit the endurance blueprint
