This 55% Yak really puts on a show at the Headcorn Southern Model Airshow in Kent, UK. Built and piloted by Steve Carr, the model uses a 500cc flat four-cylinder engine that puts out 50 horses, so the big 180-inch-span aerobat has no problem handing on the prop with plenty of power to do vertical maneuvers. Thanks to Pete and Dean Coxon for taking this great video!
