With 2020 lurching into life in some turbulence, HopFlyt promises a smooth, above-the-fray experience. A look back at an innovative aircraft designer, the new variant applies electric power and new structural techniques unknown when Willard Custer had his inspiration. HopFlyt is a modern interpretation of that vision, with distributed electric propulsion, 3D-printed components, and simplified control systems.
