Extra 300 SHPAirshow/Competition Plane
Uncertified version of the 300SHP with a Lycoming AEIO-580 engine – 300 horsepower (224 kW).
The engine is a horizontally opposed, six-cylinder aircraft engine featuring three cylinders per side. It has a fuel injection system which meters fuel in proportion to the induction airflow through air-bled nozzles at the individual cylinder intake ports. The Extra 300 has a welded steel tube fuselage covered in aluminum and fabric. The mid-set wing has a carbon fiber composite spar and carbon composite skins. Equal performance in both upright and inverted flight is provided by a symmetrical airfoil, mounted with a zero angle of incidence.1,290Lbs/585KgLycoming AE10-580Hartzell "Claw"
Edge 540 V2Red Bull Air Race Plane
Designed to be as agile in the air as possible and streamlined to perfection, the raceplanes flown in the Red Bull Air Race World Championship are at the forefront of light aviation technology.
Constructed to be as light as possible to ensure maximum speed, they also have to be extremely robust, and tolerate stressed of up to 10 times the force of gravity (10Gs).
These propeller-driven machines are highly manoeuvrable, pulling up into a vertical orientation at high speed with very little effort – something that even modern fighter jets can’t match.
In previous years, the race teams were allowed to modify their aircraft, but since 2014, the engines and propellers have been standardised for all teams. The Lycoming Thunderbolt AEIO-540-EXP engine and the Hartzell 3-bladed 7690 structural composite propeller have both undergone rigorous testing and have performed to specification. Both the pilots and their teams have instead dedicated their efforts to perfecting airframe aerodynamics, as well as pilot skill and ability.
The Edge 540, manufactured by Zivko Aeronautics, is as precise and controllable as it is aggressive. The small, one-seater aircraft is a favourite amongst Red Bull Air Race pilots, largely due to its fuselage.
The computer optimised, steel tube frame makes the Edge 540 an extremely light, very durable and easily repairable raceplane.
Using an unconventional straight-edged wing, the Edge 540 sparked much interest in flying circles around the world, particularly after Kirby Chambliss began using it for aerobatic competitions. The aircraft has since evolved into the highly refined and technologically advanced version of the original prototype, with the radical wing now acknowledged as a pioneering feat of design.
Over the last few seasons, a number of the pilots upgraded to the race-bespoke Edge V3. The V3 is different from the 540 in various ways: It has an increased tolerance of G-loads. The body has been finely tuned to increase aerodynamics and reduce drag. Modifications range from a sleeker canopy design and improved exhaust, wing root and rear wheel fairings to enhanced winglets, shorter landing gear legs and upgraded cowlings.
For 2018, the Challenger Class race plane will be the Edge 540 V2. From the birth of the Challenger Cup, the pilots flew the two-seat Extra 330LX, sharing three Extras among them at each stop. Although the Extra did its job well, for 2018 the trio of race planes have been replaced with single-seat Edge 540 V2s.1,170Lbs/531KgLycoming AEIO-540-EXP ThunderboltHartzell 3-bladed 7690
