RC Aerobatics aircraft are judged according to the degree of precision with which they are able to execute a schedule of maneuvers. These maneuvers require a high degree of piloting skill and a specialized aircraft with a great deal of power. Maneuvers must be smooth and graceful. Each is assigned a degree of difficulty, which means some maneuvers carry more point value than others. Pilots compete in classes according to their skill levels.
