HopFlyt Venturi 1/7th scale model, Dec 16, 2017

The American company HopFlyt began hovering tests of its Venturi one-seventh scale model in its hangar in Lusby, Maryland, in December. The Venturi pairs variable incidence, tandem channel wings with eight counter-rotating propellers within the channels that can generate very high levels of static thrust and lift while reducing propeller noise. “Combining these technologies,” the company said, “with [distributed electrical propulsion] reduces mechanical complexity by removing traditional flight control surfaces (i.e. ailerons, elevators, rudder and flaps). This reduces weight, improves reliability and reduces maintenance while allowing the aircraft to take off and land vertically.”
