My instructor taught me to land like this. Set the throttle at 1/2 way, and start aligning up with the runway. After you align up with the runway straight, get the plane about 20 feet above the ground when approaching the runway. If your the right height, and the plane is stable/straight, as soon as the your over the runway, cut the throttle to idle and keep the plane straight. It will land itself. And it always does.

At least with my avistar trainer.
