Copperhead Aviation Corp introduces the next generation in foamy aircraft; the Yak Stiffy. This electric powered aircraft utilizes our proprietary nake Skin Technology over EPP foam to provide a
very stiff and durable aircraft that is unmatched by other foamies. It is intended for intermediate to advanced pilots interested in mastering the most challenging aerobatic patterns and wildest 3D
maneuvers. The rigid airfoiled wing and oversized control surfaces allow the Extra exceptional performance in difficult wind conditions and at any speed. Best of all the Extra is tough; so now you
can practice the low altitude 3D stuff without fearing those inevitable mistakes that used to end your flying day.
