The Extra 330SC (single competition) is the top of the range awesome aerobatic aircraft with +10/-10 G limits. G-IIHI, it is one of the first of its type to be built, its serial number is 008 and it is entirely in a class of its own. It is fitted with the newly certified Lycoming AE10-580 engine which has been specifically developed for high performance aerobatic aircraft. The engine produces an impressive 320hp (580 cubic inches but only turning at 2700 rpm) which when you consider there is no ground resistance, is quite incredible. Its maximum diving speed is 418 km/h and it has an incredibly fast roll rate of 420 degrees per second. If the weather conditions are right, the aircraft can be seen to hover and in the right hands, it really does performs manoeuvres that should not be possible! Mark Jefferies is one of the few pilots that can fly this aircraft to its limits! As well as its sporty paint scheme, the Extra 330SC has a unique smoke system fitted which enables smoke to be “pulsed” out, offering something different to air show audiences.
With the latest technology cameras fitted to the aircraft, live footage can be transmitted to trackside screens giving the audience a bird’s eye view of the event. Cameras can be fitted anywhere on the aircraft, including inside the cockpit which gives a very interesting perspective of the world. Footage can be given directly to TV news channels to report on and promote the event or can be used later for promotional material.
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 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 engine 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.
Extra 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.
Extra 330SC – The Extra 330SC is a Lycoming AEIO-580 powered single seater aircraft with improved roll rate and easier roll stops designed specifically for Unlimited category competition.
The CAP Aviation CAP-23x family is a family of high-performance aircraft designed for competition aerobatics. The CAP 230 airframe was a direct development of the CAP 21 competition single seater strengthened to cope with a 300 hp 6-cylinder Lycoming AEIO-540 engine instead of the 200 hp original 4-cylinder Lycoming AEIO-360. The CAP 230 was primarily developed in 1985 for the French Air Force. From the basic CAP 21 airframe, trailing edge apex triangular surfaces were added to the basic trapezoidal wing. The CAP 230 keeps a full wooden construction and certified to cope with +10/-10 G-forces. The CAP 231 was developed in 1990. The fuselage design remained unchanged and only leading edge triangular apex surfaces were added to reduce buffeting during high G pullups. The CAP 231 was world champion in 1990. To increase performance, in 1991, a carbon-fiber wing taken from an EXTRA 260 (thus the -EX name) was adapted to a few CAP 231 airframes. The CAP 231EX evolved in 1994. While the fuselage construction retained wood, a carbon-fiber wing was specially designed for durability and light weight. The design has won the World Championships in 1998, 2000 and 2007, as well as a number of other national-level competitions. With a roll rate of 420° per second and a climb rate of nearly 3,300 feet per minute, the CAP-232 is still well suited for the aerobatic circuit.
