Hull is wasted on a vulture because it shouldn't be losing shields to begin with. I recommend a single 5B SCB and the rest can be anything else, but unless you want to hull tank, more than a single additional HRP as a backup in case your shields go down is a waste. As soon as the missles come flying, your modules are going to be shot out, and with no Module reinforcement packages nor point defense to take them out, that extra health is going to go to waste when it could have been used for another SCB or two. Also, your powerplant is unnecessarily overcharged. By turning off your fuel scoop and your cargo hatch, you have enough power with overcharged-1. Furthermore, engines are significantly more important than anything else for engineering when it comes to combat since AI have the advantage with near perfect flying and quite literally responding to your inputs because they do cheat.

Personally I don't recommend PAs or fixed for learning how to fight. Sometimes, depending on your hotas, it's really not ideal (my thrustmaster X has a nasty delay so I can't aim fixed well). You spend more time trying to line up a small target than focusing on evading and firing. Going with full fixed, especially ultra capacitor heavy PAs with a vulture is asking for a bad time if you have no basis for combat because it tests everything at once: evasion, weapon precision, pip management, and positioning against your enemy. Go gimballed weapons, go full evasive. Hone your evasive skills first before focusing on fixed. The brain can only focus on one thing at a time, and while the vulture is tanky enough that it has enough leeway to absorb blows while focusing fixed fire, it'll be much harder to fly precisely when you're trying to aim precisely. After a time, you might want to swap one of the gimballed weapons to fixed so you have a mixed loadout on your vulture.
