From the Back Cover:
Next to flying aerobatically themselves, this book is the closest pilots can get to the advanced aerobatic experience. For many pilots who do want or need to learn specific maneuvers, there is no better guidance than this book. A lesson by lesson guide, it combines accessible text from aerobatic champions with sequential cockpit view photographs and detailed graphic illustration to provide a hands-on primer on specific advanced aerobatic maneuvers.
Each maneuver is given an entire chapter with a clear description of its elements; discussion of the theory behind it; step by step details on how to fly it; a look at the finer points and common errors; and corrective measures to take if something goes wrong.
