The infamous prop copter, there are pictures of it but they're knockoffs of Benson's design
People were selling drawings, infact Vortech still sells the plans, they have a few pictures but nobody's flown one.
It's like the propane powered tip Jet Helicopter. Ramjet tip jet helicopters actually flew but none of the propane ones fly they don't develop enough thrust.
