Questions about Building a Space Station on orbit

[Turk_WLF]

I’m wondering how to assemble a station on orbit but more so about the arranging the modules like Cupola (From the Mini Shuttle Mod), I’ve launched it into orbit in a vertical stock configuration with a T Node and a Habit module with Docking Ports on with ends of the T Node and the Cupola where needed. As soon as I decouple the docking nodes the Cupola launches about good 75 meters.

Is there a way I can keep the Cupola from launching or moving it in to the location that I want it to be. I’m using the Mini Shuttle’s Space Tug to move the modules.

Thanks,

You may want to use a docking ring to attach the to parts, so you don't fire your load off into space. (phrasing)....

Or you should use a seperator instead of a decoupler. I have built a few space stations in orbit, my last one was for a challenge a few months ago. And I am in the process of building another.

You can flip through this album and see pretty much how I did it. Mind you I use space planes almost exclusively.

Use a docking port to hold it down. Then simply undock and back away.
