Stand Up and Fly (Aug, 1955)
Stand Up and Fly
You’re a human hummingbird on the new de Lackner helicopter.
LIKE the flying manhole cover, the new de Lackner helicopter carries only one man who hangs on to handlebars, controls pitch and roll by shifting his weight. Unlike the manhole cover, it is very light (a 125-lb. model is planned) and it is amphibious. Maximum cargo: 200 lbs. Cargo-lifting line runs down through hollow rotor shaft; this method frees copter of cargo inertia during pitch and roll. Top speed is 65 mph, hovering ceiling is 5,000 feet, fuel capacity is one gallon, range is 15 miles. Auxiliary five-gallon fuel tank boosts range to 50 miles. Builders are de Lackner Helicopters, who have named it the Heli-Vector.
