Unfortunately I don't think it's that, I enabled advanced tweakables and checked everything like that. Okay, I'm experimenting a bit more and it seems like the problem is the rotatrons being placed directly on a structural fuselage. If I place them instead on a truss frame attached to the fuselage it's all good.

When I place a servo rotatron in 1.10.1, it refuses to rotate, and just sort of jerks about like it's fighting something that's trying to keep it in its original position. I don't have Kerbal Joint Reinforcement.
