The Vulture does not need gimballed anything. Trust me.
I used a lot of gimballed weapons in my Cobra and then naturally wanted them on my Vulture. After reading a lot of postings here that kept saying there is no need of gimbals, I decided to give a fixed beam a go and now am firmly in that camp.
I currently rock a 3C beam and 3c turreted cannon. Others might have a different opinion about the load-out, but it works for me nicely.
Glad to help.
Just keep close to your target and dance around it. Fry his ass with the beam.
The cannon (if you go that route) takes some practice. Don't fire it off on small targets unless you are right on top of them (too easy to miss). I save the cannon as a finisher for small guys when in close, but use it liberally on large targets after I melt their shields.
