The Aircraft
The Extra 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. Tamás Nádas flies the Extra 300 LP model.
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 fibreglass and fabric. The mid-set wing has a carbon fibre composite spar and fibreglass 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 tail dragger style with composite main legs and fibreglass wheel pants. The power plant is a fuel-injected Lycoming AEIO-540 which produces 300 horsepower (224 kW).
The Extra 300 is stressed for ±10 G with one person on board and ±8 G with two.
