Bob Hoover, a well known aerobatic, test, and combat pilot, used to do an airshow routine in a shrike commander. It involved a full aerobatic demonstration on both engines. Then he would shut down one engine and perform the routine, then shut down the second engine and perform it without power. It's a matter of energy management and airmanship, and he did a superb job. The mere fact that he had no power available didn't hinder his ability to control the airplane. In fact, part of his routine was returning the airplane to it's starting point after the power off routine...still without power.
I had the privilege of seeing Bob Hoover's airshow routine once. Absolutely incredible.
