Yeah. But you have to do jobs for them too which is a grind if I understand correctly.
Yes it is! Does it make a difference? Oh Hell YES!!
As an example lets look at FSD jump ranges.
stock jump / engineered
Vulture 8 ly / 20.5 ly
Asp Explorer 14 ly / 49.8 ly
FAS 8.3 ly / 23.7 ly
Chieftain 8 ?? ly / 26.7 ly
Python 8.6 ly / 24.9 ly
On one of the engineers I had to mine 10 tones of Panite to give to her and have a total of over 500 tones materials mined. Well, I sucked it up and did it made some money on all the other minerals I sold off. Oh, BTW on the way to deliver I got interdicted and killed! Rinse and repeat!
Asp Explorer is the ship I used most often to unlock the engineers due to its range.
Come join our group sometime as we bounty hunt. We make good money and can scoop materials as well.
