Air Race aircraft have to be extremely stable. During a steep turn, both pilot and plane are subjected to forces which can reach up to 10G, meaning they are ten times their normal weight. In principle, the plane should also be as lightweight as possible, and not just because of the high G-forces. Modern aircraft seldom weigh more than 600 kilos because they are constructed using extremely light but very stiff composite materials, such as carbon fibre. Their light weight combined with a highly efficient steering system results in an agility that normal aircraft, even modern fighter jets, cannot begin to match.
Among the few aircraft that are suitable for racing, there are differences in engine power and flying performance that can have an important influence on the pilot’s chances of winning. The Zivko Edge 540 is currently considered the best: with a top speed of 426 kph and weight of only 530 kg, it can withstand forces of up to 15G. This was the plane in which Mike Mangold won five out seven races in the 2005 World Series and gained him the title of the Championship.
Zivko Edge 540
Zivko Aeronautics of Oklahoma had a mission to produce a plane that could perform precise standard manoeuvres at speed and leave ample creative room for professionals to develop new figures. The result of these considerations is the Edge 540. The small one-seater airplane (a two-seater version is also available) is as precise and controllable as it is aggressive. The Edge is a ‘Shoulder Wing’ plane with extremely stiff wings. The fuselage is also exceedingly stable and resists forces of up to 15G. The Edge is the favourite of the American pilots Mike Mangold and Kirby Chambliss. Read More About the Upcoming Air Race October 7th

Extra 300S
The Extra 300S is one of the most successful and commercial aerobatic planes in the history of flying. They are manufactured in Germany and are made from a combination of carbon fibre, steel tubing and aluminium sheeting, which helps to reduce weight and increase resilience. The founder of the company which produces the plane – Walter Extra – was an aerobatic pilot himself and his aircraft are now used by pilots across the world.
Pilots who fly his planes are able to perform the most extreme manoeuvres as they spin through the air with few limitations. It is a single-seater Extra aircraft as used by Britons Steve Jones, Paul Bonhomme, Nigel Lamb, the Hungarian Peter Besenyei and Dutchman Frank Versteegh.
