not so confident about the hovering bit...
It's all in controlling the attitude - keep it flat.
Make it point (absolutely important. you cannot hover if you don't control the direction)
Keep it flat (with small fingertip movements) . When the qfi shows you the correct hover attitude, remember where it crosses the window in front of you.
Then fix the height. You will never hit the ground, because you will flinch away from it with a big collective movement, and the secondary effects of that will f*** you up for a few seconds.
The fixed-wing pilots converting across generally can do the upper air work straight away, using attitude for airspeed, but forget to just keep the attitude steady when they are in the hover - fixating on a blade of grass. Now using attitude for groundspeed, of zero. In an R22, one demo for the students is to have one foot on the pedal, left hand in the air, and one fingertip on the top of the cyclic. Not much effort needed to make it work.
