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 midset wing has a carbon fiber composite spar and carbon composite skins.[1] 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.[1]

The Extra 300 is stressed for ±10 G with one person on board and ±8 G with two. Some Extra 300s are registered in the experimental category under a Special Certificate of Airworthiness in the U.S., while others are type certified in the aerobatic category.[2]

Variants

300

Original two-seat version[3]

300S

The 300S is a single-seat version, with a wingspan reduced by 50 cm (19+1⁄2 in), and fitted with larger ailerons.[1][3]

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.[4] 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.

300L

The Extra 300L is a Lycoming AEIO-540-powered two-seat aircraft, with low-mounted wing and shorter fuselage.[3] More of these two-seater variants 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 (7.9 to 7.3 m). Improved ailerons boost the 300L's roll rate to 400° per second. All 300Ls are fully certified under FAA and European Joint Aviation Authorities regulations.

300LP

The 300LP (P = 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

The Extra 330LT is a Lycoming AEIO-580 powered two-seat aircraft, adapted for touring. It has an EFIS cockpit and a reduced roll rate in comparison with the 330LX.

330LE

The Extra 330LE is a one-seat aircraft powered by an electric engine made by Siemens, delivering 260 kW, for 50 kg. On Thursday, March 23, 2017, the Extra 330LE set two new speed records, said Siemens : "At the Dinslaken Schwarze Heide airfield in Germany, the electric aircraft reached a top speed of around 340 kilometers per hour (km/h) over a distance of three kilometers. On Friday, March 24, 2017, the Extra 330LE gave another premiere performance by becoming the world's first electric aircraft to tow a glider into the sky".[5]
