I think the basics are key: If you're flying "normal style" and giving an input on any control surface, (irregardless of plane orientation ie up, down, belly to you, away from you, torwards or away from you, etc) and then saying oops, wrong way, you're not ready yet. A sim can help here. A TR on the deck can be learned in RF. It won't be the same in real life, but you'll know what to do when the plane suprises you. After the basics, push the envelope. I stayed up high hovering for a summer, and when I finally did get the nerve to go low, I found it was no big deal. You've got to take pretty big steps or you'll never get there, but, make sure you have the basics down first.
