Extra Aircraft Extra 330 Lx vs Zivko Edge 540

The Extra Aircraft Extra 330 LX and the Zivko Edge 540 are both single-engine, piston-powered aerobatic airplanes designed primarily for competition and advanced aerobatics rather than transportation. In category terms, each sits firmly in the high-performance aerobatic/airshow class, optimized for maneuverability, roll rate, and structural strength over cross-country utility. For range, both aircraft typically have relatively short endurance compared with touring airplanes; the Extra 330 LX is generally described with a modest cross-country capability, while the Edge 540 is likewise limited, with practical range strongly dependent on aerobatic fuel reserves and operating power settings. Passenger capacity is effectively the same in typical use: both are flown as single-seat aerobatic machines for competition, though some variants within each family exist with two-seat configurations for training or demonstration; the Extra 330 “LX” and common Edge 540 competition setups are usually configured for one pilot rather than carrying passengers.
