Warhawk is great! PS3 must have for sure.
You must use the sixaxis!! I found the controlling and fighting to be much better in the warhawk using the sixaxis. No joke, dogfighting is a ton easier once you get used to it. what I would do is just create a game and fly around not shooting for a while and manuever through all the tunnels etc, now I can hold my own in any server flying....usually. lol
The one thing that is ackward is driving, can't really get used to it but the sixaxis for flying I think at least, is the way flying should be. Learning curve is a little bit, but I think it works really, really well.
(if you are really good, you can aim and fly at the same time, not to mention the barrel rolsl and flips are a ton easier using the motion controls, if you use PRO FLIGHT, you are definitely elite in Warhawk...)
