I agree with adrian when he says practice practice practice!!!

I see so many people asking how to do these manuvers. The sites listed above are good places to start but dont expect to just be able to go out and put in the motions given on the sticks and poof! 3D appears. With the exception of the blender, most of the 3D manuvers have a feel for them. I could explain to you how to do a torque roll until I am blue in the face but your not going to be able to just go out and do it. Its sort of like driving a straight shift automobile. People can tell you that you press in the clutch and add gas and realease the clutch but until you try it many times your not going to figure it out. Someone once told me they could teach anybody to hover for $100. They said buy $100 worth of fuel and practice hovering constantly until the $100 worth of fuel is all gone
