As an alternative fast travel the V-bird taxi is just great. One of the better addition to the series if you ask me.
But what is the point of the minigun? If there's an attack on the place you're going to, the V-bird lands before you can use the minigun. And more or less every time some raider or psycho or mutant shoots at you while flying, they shoot at you from the right side of the V-bird, and your gun is facing the left side..
I'm close to the end of the story by now, and all I've been using the minigun for so far, is to blow up cars on my way to next landing..
The V-bird minigun could have been such a cool ferature, but it's actually pointless as I see it. Have I missed something that would make it usefull in some way?
