Beta’s prototype, based on an RDD LX7, uses eight electric motors driving one fixed-pitch propeller each. These are mounted on rotating tubular arms that allow vertical takeoffs and landings with the propellers in horizontal orientation and a claimed 170 mph cruise when in vertical orientation. VT Digger, an independent non-profit journal, reports, “Using homemade flight simulators, an array of 3D printers, a machine shop, and a team of nearly 40 staff and contracted engineers, Clark has big plans for his self-funded company, which occupies a hangar and other buildings at the Burlington airport. He intends to stand out for creating an aircraft with a power system that enables it to achieve the longest flight range amongst its peers.” “’We’re going to develop the world’s longest-range, best-performing aircraft,’ he said.” Wired, in a snarky mode, describes the Beta Ava as looking, “like what Tony Stark would build …
