sounds like you have your channels a little screwy and although you are doing well on the simulator, its wash because you have different controls on your heli.
The left stick is your throttle/collective. This is the up and down motion that makes you lift off. Pushing it left or right spins the heli to face different directions.(on a normal setup) When grounded if you push it to one side and the tail spins, i believe this is normal. It is supposed to do that to compensate in the air. Someone else can explain that better but i know its normal.
I am no guru. I am still waiting for my Aerohawk, which is on backorder for the past month and 1/2 from hobby-lobby. I'm sure someone else could explain this a little better but since i saw you have 0 replies i figured i would give it a go. And in the interim, bump your post.
Good luck to you..
