Okay, so I've bought some A-rated SCO FSD drives for my fleet but, being cautious about grind, I thought I'd just engineer
one of them first to see the result.
From the videos seen online it looks like the basic SCO drives have a range of about 2ly more than conventional FSDs.
I engineered my shuttlebus Diamondback Explorer, which with a regular FSD had a range of
73.96ly using Increased Range and Mass Manager...
...but now it's got a range of just
74.18ly. That's an increase of just
0.22ly.
Given the grind in collecting mats for engineering I don't think this is going to be worth it on any ship you already have fully engineered and don't need to scrape the last final bit of range out of
