Extra 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.
The 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 fibre 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 fibreglass wheel pants. The powerplant is a Lycoming AEIO-580 EXP which produces 325 horsepower.
The Extra 300 is stressed for ±10 G with one person on board and ±8 G with two. Some Extra 300s are certified in the experimental category in the U.S., while others are certified in the aerobatic category
