Here's something that I did and it seemed to help a little. Of course the best thing is to fly a lot, but this trick is a freebee.
Just before you go to sleep, picture yourself flying the heli and work the controls with your eyes closed. No distractions, no errors. In your mind you know what to do, but in real flight there are errors which lead to emergencies, and that leads to crashes and frustration.
"See" the heli and work the controls - move your thumbs - and "see" the results. Repeat, repeat, repeat. It burns it into your memory. When it comes natural, turn the heli in your mind so it's nose in and practice. It's surprising that, in your mind, you will hesitate and frequently make the mistakes you make in real flight.
