Extra Aircraft Extra 330 Sc vs Zivko Edge 540

The Extra Aircraft Extra 330 SC and the Zivko Edge 540 are both single-seat, high-performance aerobatic aircraft designed primarily for unlimited-category competition rather than cross-country travel. In category terms, each is best described as a specialized aerobatic/competition airplane with very high roll rates and strong vertical performance; the Extra 330 SC is often associated with a slightly more “all-around” aerobatic feel and broader training/show use, while the Edge 540 is widely optimized around aggressive, precision aerobatics commonly seen in air-racing and top-tier freestyle routines. Range is limited on both because fuel capacity is secondary to low weight and maneuverability. Typical real-world endurance is often on the order of roughly an hour to a couple of hours depending on power settings, with the Extra 330 SC frequently cited with somewhat longer practical range than the Edge 540, though exact figures vary by configuration and operating profile. Passenger capacity is essentially the same: both are single-seat aircraft intended for one pilot only, with no provision for carrying passengers.
