I've been an instructor for many years, and (CrazyInTheAir) said it best in a previous post. Use Throttle,Elevator to control your descent. Most newer pilots tend to be in a hurry to land and force the plane down. Don't be! Come around again if it's not feeling good. This is what I teach. Keep the nose of the plane slightly up during the descent. You do this with the elevator(use short blips). Try not to let the nose fall. That's why the front gear is always bent up on a trainer. If you start stalling, shoot a very short burst of throttle into the engine, and then come back to idle. This will keep you flying. Remember, a landing is merely a controlled stall. Practice, practice, practice. Good luck!
