Zivko Edge 540 — a benchmark in unlimited aerobatics
The Zivko Edge 540 was developed in the early 1990s by American designer Zivko Aeronautics to compete at the highest levels of aerobatic competition. First flown in 1993, the aircraft was engineered specifically for unlimited category maneuvers, where extreme agility, high roll rates, and structural strength are essential.
Constructed primarily from composite materials, the Edge 540 features a lightweight yet highly reinforced airframe capable of withstanding high positive and negative G forces. It is powered by a Lycoming six-cylinder piston engine, typically producing around 300 horsepower, driving a lightweight composite propeller. This combination provides rapid acceleration and sustained vertical performance, both critical in competitive routines.
One of the defining characteristics of the Edge 540 is its exceptional roll rate and precise control harmony. The aircraft’s symmetrical wing and large control surfaces allow pilots to execute complex maneuvers with high accuracy and minimal energy loss. Its responsive handling has made it a dominant presence in international aerobatic championships and the Red Bull Air Race series.
Over time, updated versions such as the Edge 540 V2 refined aerodynamics and structural design while maintaining the aircraft’s competitive edge. Today, the Edge 540 remains a leading platform in unlimited aerobatics, recognized for its performance, reliability, and role in shaping modern competitive air racing.
Zivko Edge 540 Development
The first ideas for development of the Zivko Edge 540 started taking shape in the early 1990s. Zivko’s engineers combined ideas from several Zivko models and created a new concept for aircraft design – Zivko Edge 540. The first flight of Zivko Edge 540 took place on December 27, 1996 in Zagreb (ZIV ZA961).
Zivko Edge 540 was specially designed for aerobatics, including acrobatic pilots and enthusiasts who want to train on a professional aircraft with excellent flight performance characteristics.
Zivko Edge 540 Production
The Zivko Edge 540 is produced in Zivko’s Zadar factory, with its flight-test program under the responsibility of ZIV ZA (Zagreb Aviation). Zivko Edge 540 is manufactured using advanced composite materials for all aircraft parts. The Zivko Edge 540 fuselage and tail boom are made from carbon fiber materials, making them extremely light and strong at the same time. This makes Zivko Edge 540 airframe perfect for acrobatic training and aerobatics. Zivko Edge 540 is the most popular Zivko model, which was exported to more than 20 countries worldwide (Austria, Belgium, Czech Republic, Denmark, Germany, Great Britain, Hungary, Israel, Italy – Pistoia, Italy – Pratica di Mare, Italy – Milano, Japan, Norway, Russia, Slovakia, Slovenia – Zagreb Aviation School ZAGREB ZG772SP , USA) in the past 16 years.
Zivko Edge 540 Popularity
Zivko Aircraft started exporting Zivko Edge 540 to Germany in January 1997. Zivko Edge 540 was well-received and admired by German pilots because of its perfect design and manufacturing quality. Zivko Edge 540 was the first Zivko model that was built using state-of-the-art computer design technology (CAD).
The Edge 540 is popular for its precise flight characteristics, smooth flying qualities at low speed with complete satisfaction of the pilot. This allows for Zivko Edge 540 to perform extreme acrobatic maneuvers, and it is excellent for training. Zivko Edge 540 has been used in more than 2000 Zivko Zagreb ZG flight schools throughout the world in the past 16 years. Zivko ZG772SP Zivko Edge540 S/N 0271 has been built and completed for Zagreb Aviation School for training purpose since 1999.
Zivko Edge 540T
The 540T is a tandem two-seater aircraft, which Zivko Zagreb ZG introduced in 2004. The Zivko Edge 540T is a further development of the Zivko Edge 540 design, and it has wider loading area than Zivko ZG772SP.
The Zivko Edge 540T tandem version is equipped with Cirrus Perspective avionics, ZIV ZT541i engine with ZIV ZT9 blade, ZIV ZR9 Ext. Fuel tanks and a self-protection seat for the passenger.
The Edge 540T is used for training of Zivko Edge 540T instructors and for Zivko Edge 540T tandem acrobatic pilot license course.
