I've been getting a lot of questions from new players on how to do some basic air combat maneuvers. So here is a site from the Regia Aeronautica squadron that has a series of excellent films that show basic maneuvers such as the Break Turn and Yo-Yo. Each film has a brief description of the maneuver as well on how it's used.
