Can someone help me please?
I started to build an SLS with the parts of this mod but everytime i tried to launch it, it exploded right on the Launchpad.
So I copied the file from the VAB folder, to check whether it will work or not - same problem.
After many tries I got the baby out of the low atmosphere, then the white parts and the second stage started tp become very unstabile an exploded. I tried to reinforce the second stage with some struts to the decoupler but didn't help.
