How do you build a weight-optimised aerobatic model? What is the best way to handle electrical technology? How is such a model optimally trimmed? What use can be made of the new remote-control technology and telemetry data? The author Lothar Beyer answers these and many other fundamental questions from his decades of aerobatic experience. In addition, the various groups of aerobatic manoeuvres are described in detail in an illustrative manner. Numerous illustrations and tables help to understand and practice the complex matter of aerobatics. Anyone who has mastered an aileron model safely and is looking for further know-how will find the way to becoming a successful aerobatic pilot with this book.
