The Extra Flugzeugbau EA300 is a two-seat aerobatic monoplane capable of Unlimited category competition. It was designed in 1987 by Walter Extra, an award-winning German aerobatic pilot and built by Extra Flugzeugbau.

Design and development

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

  • EA-300
    Original two-seat version.
  • EA-300S
    The 300S is a single-seat version, with a wingspan reduced by 50 cm (19½ in), and fitted with larger ailerons.
  • EA-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 (246 kW). Some 300Ss were sold with the "bigger tail" of the 330SX.
  • EA-300L
    Two seat version 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 ft 3 in (8.00 m) to 24 ft 3 in (7.39 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.
  • EA-300LP
    The 300LP ("P" for performance) is a reduced weight version of the 300L, re-designed for better performance in competitions and airshows.
  • EA-300SP
    The 300SP is a performance version of the 300S single-seater. Weight was reduced, and the tail of the 330SX installed.
  • EA-300SHP
    The 300SHP (HP=High performance) is a yet-uncertified version of the 300SP with an AEIO-580 engine.
  • EA-300SR
    The Extra 300SR is a modified aircraft using a specially designed high-lift wing for the Red Bull Air Race World Series.
  • EA-330SC
    The Extra 330SC is a Lycoming AEIO-580 powered single place aircraft with improved roll rate and easier roll stops, designed specifically for Unlimited category competition.
