No. And Guardian stuff has no effect. It’s just how SCO works.
The new ships released last year, starting with the Python mkII and including T-8, Mandalay and now Cobra mkV, are all SCO native and have much better performance and heat management with the SCO drives when using the SCO feature.So, I'm guessing the SCO is only for increased jump range, without actually being used. That would only be viable for visiting Beagle Point and other systems beyond 75 ly distance.
How do I know, which ships can handle SCO, just like the Mandalay?
