For what it’s worth, while the flying controls aren’t perfect, they’re far from the worst I’ve ever seen. 1st person is hard b/c you can’t control the camera and look around or lock your view onto your target (that I’ve found anyway). But third person is fine b/c the view is wide enough to keep track of your target. I’ve had no problem doing fine in aerial battles or blowing away vehicles and troops on the ground.
I’m playing on a PS4 with the standard controller. I can’t imagine ever wanting to play a flying game with a mouse… Blech!
