One little "training stunt", as one of my former students called it, I do is to kill the engine when it's least expected and make them dead stick back to the runway. I'll unexpectedly take control on the master (with a buddy box system), reduce quickly to idle, kill the engine and give it back to my student. They have no choice but to learn to fly it down and land it. If I'm using only a single TX, I'll just reach over and do basically the same thing, but tell them to run the trim down to kill the engine. Its amazing when, under the control of an instructor, how well someone not only can pick up on flying and landing a plane deadstick (after realizing a trainer almost seems to fly better gliding w/o power), but also learn not to panic.

Learning to fly and land while dead stick is one of the most essential parts of flying a pilot needs to learn. Unfortunately deadstick flying and slow flight/stall series are often over looked.
