Dad was always a real downer on our insulator collecting interests when we were kids, but had a keen interest in experimental aircraft that could have been real handy for picking. Dad never called his rotary wing aircraft "helicopters" like most people today, preferring the term "whirligig". He also liked using whale blubber as fuel, as its BTU delivery produced excellent results in propulsion, in spite of starting large brush and forest fires. Here we see him in a test craft used to prove a three rotor design. It was his goal to develop a single rotor craft of the smallest and simplest design. He achieved success with a T-frame unit sporting only a single school chair, Hudson six cylinder engine and a down draft exhaust in 1956. Controls were a simple cord and pulley system worked with the feet. He flew this craft until his death in 1990
