Flying with a keyboard and Mouse

One thing I always do is up the sensitivity in heli and up the FOV higher, so I can move and sway it left and right or in circles easier, also play with invert controls on or off, I forget default is on, I turn mine off. When I have to dodge 300 missiles coming at me I always go 1st person and just chill or careful flying I do 3rd person and it helps watching for other air.

Just be careful trusting random gunners, almost no one knows how to gun or let alone listen to your pings, sometimes you may need to spoon feed them kills. Fly safe unless you know exactly what you're doing and fighting against.

Flying a little bit in your own custom game helps a lot if you want to get the feel of airpower better or see what you can get away with as far as sway and how you can do circles on flags. A lot of buildings and tunnels you can fly in almost no one does, your biggest annoyance will probably be tank campers or aa campers, who do nothing entire game but camp 1 spot.
