In addition to jmir's suggestions, which are very good, you need to practice, practice, practice, practice. Hovering or prop hanging as some call it isn't easy. A few years ago I made the comment to my nephew that I would never be able to do it, I am too old. My reflexes are too slow. He said nonsense, keep trying, so I did. Guess what, I now have a 50cc Extra that I can touch the tail to the ground on without even thinking about it. You have to practice enough so that the inputs become a reflex rather than a thought. You literally anticipate what the plane is going to do next and react as it does it rather than a second too late. Don't get discouraged, it will come to you. All of a sudden, one day, you're gonna say, hey this is easy.
