I love flying around in a heli lol...im not that good though, more of an AA man myself...but it took me about 2 weeks overall to be able to get in it and fly it , and get a kill or two , I just use the mousee and keybaord .
Well i've tried it, can fly a bit but that's it. When it comes to aiming i'm crap so i've given up. Might try it in the future.
Mouse and keyboard all the way for helicopters.
