I have some issues with wobbling, to be exact with the Sarnus V (Saturn V) parts. When I built it myself, it wobbled like crazy at launch.
But when I downloaded your .craft file of the Sarnus nothing wobbled. Then I tried to connect it with the CSM+LEM .craft file and it wobbled again.
Is there anything that can stabilize the spacecraft? Or how did you make the wobble stop of your .craft files?
