if your sim program matches the cyclic and collective responses of your heli, then you can do anything with the heli that you can do on the sim. just do it up high until you're comfortable with it. it's about choosing whether you want to conquer a maneuver or surrender to the fear of crashing, which isn't the end of the world. and forget the invert switch. i learned switched inverted first and it was really difficult to unlearn it and fly switchless.
