You can have NPC crew on a Vulture? #DoesNotCompute
It was in my Keelback that I flew for a bit. I'd take the fighter while they took the helm and drew fire. Almost made me sell my Vulture because of how well it worked, but it didn't make very much money because I couldn't take on the big money makers alone. The Vulture hasn't been much better. It has the firepower to take down some of the bigger ships, but NPC's use better parts and engineering now. I tried to fight an Anaconda the other day and couldn't even get the shields down because they recharged so fast. I tried Hazardous Res sites but at most I make under 200,000 per ship and I've had an issue with the Vulture's canopy busting at the slightest amount of damage (Had to go back at 85% hull one time). The fights are also longer, so I don't end up making more CR/hr than I do in a normal res site, but the cost of the ship, price of ammo/repairs, and the skill required are much higher.
I've strongly considered selling the Vulture (17Mil CR) and just doing shipping in my AspX. Last shipping run I did, I made 1.5Mil in 30 minutes. With bounty hunting, I'm lucky to pocket 1Mil CR for an hour of work, but I usually don't between the cops killing everyone, other CMDR's killing everyone, or the Vulture getting too beat up. It was profitable early in the game, but I don't think it's worth it now.
