Extra Aircraft Extra 330 Lx vs Zivko Edge 540 vs Zivko Edge 540t

The Extra Aircraft Extra 330 LX, Zivko Edge 540, and Zivko Edge 540T are all purpose-built aerobatic airplanes, but they differ in mission emphasis and basic utility. In category, the Extra 330 LX is commonly positioned as a high-performance aerobatic monoplane used for advanced competition, training, and airshow work, while the Edge 540 is a lighter, very high roll-rate aerobatic design optimized for top-level aerobatic competition and demonstration flying. The Edge 540T is a tandem-seat variant intended to add training and dual-control capability while retaining an aerobatic focus. In range, all three have relatively short practical cross-country capability compared with touring aircraft because they prioritize low weight and aerobatic performance. The Extra 330 LX is often regarded as having a modestly better practical range/endurance than the single-seat Edge 540 due to configuration choices and typical fuel capacity, while the Edge 540T can vary but is generally similar in spirit and still limited by aerobatic-design constraints. In passenger capacity, the Edge 540 is typically single-seat, the Edge 540T is two-seat tandem, and the Extra 330 LX is commonly a single-seat aerobatic aircraft.
