The Zivko Edge 540 manufactured by Zivko Aeronautics is a highly aerobatic aircraft. Capable of a 420 degree per second roll rate and a 3,700 foot per minute climb rate, it has been flown to victory on the international Unlimited aerobatics circuit several times since the mid-1990s. A tandem-seat version is sold as the Edge 540T.
The Zivko Edge 540 is the most common aircraft used in the Red Bull Air Race World Series.
