Red Bull Monster Scale Yak
This 55% Yak can really put on a show! Scratch-built and piloted by Steve Carr, the big 180-inch-span aerobat is powered by a 500cc 4-stroke engine that produces 50 horsepower and uses a Weatronic radio system. Thanks to Pete and Dean Coxon for filming this beast at an old U.S. airbase in Rougham, UK.
