The Zivko Edge 540 in 1.20-class size from Seagull Models — the Red Bull Air Race champion captured in mid-class ARF form.
The Zivko Edge 540 is the dominant unlimited-aerobatic airframe of the modern era. This RC implementation is from Seagull Models, a Vietnamese-owned RC manufacturer producing balsa-and-ply ARFs at multiple engine classes. The "1.20" suffix refers to the 1.20-cubic-inch (about 20cc) engine class — the upper end of conventional sport-aerobatic ARF sizing. A natural sibling of the broader Edge 540 family.
A demanding aerobatic mount in the mid-large ARF class. Use it for serious aerobatic flying.
