Why does this roll?

Wish I could've provided a specific fix (if there even is one). Just know that those rotators and henge rotators can be finicky if not connected in very particular ways!

Ok thank you for your feedback @Toinkove.

Ok yeah, Starts spinning the second I load it into orbit! And it is related to the 4 hinge rotators (one on top of another on either side) that connect to the main landing legs! When I remove them, the spin goes away!

I'm just not sure what causes that. If there is some torque or tension in them or maybe a collision response occurring with other parts. But you'll have to figure that out or redesign the landing leg.

Well there's slight miss alignment between center of mass and center of gravity. But very small shouldn't be that bad.
....
The only thing that looks suspect is the landing legs! You've obviously constructed them yourself using a shock absorber and many hinge rotators. I'm only mentioning this cause I have had hinge rotators behave oddly sometimes (for reasons I still do not fully understand). On occasion I have extended a henge rotator that once fully extended will then impart a slight spin to a craft that gets increasingly more violent over time. But this theory is just a shot in the dark.
.......
Is there a particular action that leads to the spinning? A way I can reproduce the spinning you're experiencing to determine a cause?
