I was reading another thread where people were talking about helicopter tactics and some people said they couldn't fly. I find it disappointing that there is no means to practice flying outside of ranked play (or MP altogether) but that is an unfortunately currently unchangeable problem. Now, I'm sure flying for the PC is similar to how it has been in previous BF iterations and it isn't too hard, but the console configuration means that you've got a bit of difference to accommodate and, invariably, people don't take off. They just crash. And then people moan at them for using 'their' vehicle (because they're owned, right??) and that isn't fair.
So, for those interested, here's some links to some helicopter tutorials for the console. The tutorial uses the 360, but I imagine it'd be the same for the PS3, just changing the name of some buttons. Even if you think the voice patronising, they're very good and thorough. The same guy did a tutorial for BC1 which I used and can attest to it's brilliance. In fact, there's very little difference between controlling in BC1 to BC2. That being said, you'll likely want to change the control method (options) to the BC1 set-up. Apparently this makes circle-strafing harder to do, but it's not something I do anyhow, so if the basics below are useful, you can theoretically use any set-up that you would otherwise prefer.
Enjoy guys, and see you on the Battlefield!
