As everyone pointed out the mechanics of getting back on the ground, I will point out one thing myself. Practice, practice, practice. You simply have to spend time flying and landing to get this understood between your brain and your fingers. Someone mentioned touch and go's, that is an excellent way to get in practice. I spend a lot of time shooting touch and go's with my trainer plane and my intermediate models, there is no substitute for experience, and the only way to gain it is to just keep doing it. By the end of your first session, you will have learned a lot, by the end of your first season, you will have made great gains in your skill. Just keep practicing.
