Extra 300 pov aerobatics
The Extra Flugzeugbau EA300 is a two-seat aerobatic monoplane capable of Unlimited category competition. It was designed in 1987 by Walter Extra, a German aerobatic pilot, and built by Extra Flugzeugbau.
Design of the Extra 300 was based on the Extra 230, an early 1980s monoplane having a wing made of wood. The Extra 300 has a welded steel tube fuselage covered in aluminium and fabric. The mid-set wing has a carbon fiber composite spar and carbon composite skins. A symmetrical airfoil, mounted with a zero angle of incidence, provides equal performance in both upright and inverted flight. The landing gear is fixed taildragger style with composite main legs and fiberglass wheel pants. The powerplant is a fuel-injected Lycoming AEIO-540 which produces 300 horsepower (224 kW).
The first two-seat Extra 300 made its maiden flight on 6 May 1988, with German type certification following on 16 May 1990. The single-seat Extra 300S flew on 4 March 1992.
The Extra 300 is stressed for ±10 G with one person on board and ±8 G with two. Some Extra 300s are certificated in the Experimental Category in the U.S., while others are certificated in the Aerobatic category.
Variants
300
Original two-seat version.
300S
The 300S is a single-seat version, with a wingspan reduced by 50 cm (191⁄2 in), and fitted with larger ailerons.
330SX
The Extra 330SX was a custom development of the 300S with a wider-chord rudder, a larger elevator, and a more powerful Lycoming AEIO-580 powerplant producing 330 hp (250 kW). Some 300Ss were sold with the "bigger tail" of the 330SX. The 330SX was later replaced by the 330SC.
300SP
The 300SP is a performance version of the 300S single-seater. Weight was reduced, and the tail of the 330SX installed. It is discontinued, being replaced by the 330SC.
300SHP
The 300SHP (HP=High performance) is an uncertified version of the 300SP with a Lycoming AEIO-580 engine.
300SR
The Extra 300SR is a modified aircraft using a specially designed high-lift wing for the Red Bull Air Race World Series. It made promising debuts in July 2007, but has yet to challenge the dominance of the Zivko Edge 540.
300L
The Extra 300L is a Lycoming AEIO-540 powered two-seat aircraft, with low mounted wing and shorter fuselage. More Extra 300L ("L" is a 2 seater version) aircraft have been produced than any other model. Its wing is mounted at the bottom of the fuselage, with its span reduced from 26 to 24 ft (7.925 to 7.315 m). Improved ailerons boost the 300L's roll rate to 400 degrees per second. All 300Ls are fully certified under FAA and European Joint Aviation Authorities regulations.
300LP
The 300LP ("P" for performance) is a reduced weight version of the 300L, redesigned for better performance in competitions and airshows.
330SC
The Extra 330SC is a Lycoming AEIO-580-powered single-seat aircraft with improved roll rate and easier roll stops, designed specifically for Unlimited category competition. It is the only single-seater aerobatic aircraft currently being built by Extra.
330LX
The Extra 330LX is a Lycoming AEIO-580-powered two-seat aircraft.
330LT

An Extra 300 owned and flown by Chuck Coleman was one of the official chase planes of Burt Rutan's SpaceShipOne and Virgin Atlantic GlobalFlyer (during flight test).
Patty Wagstaff has flown the Extra 230, 260 and various models of the 300 in aerobatic competitions and airshows since the mid-1980s.
