Uber reveals its latest “flying car” prototype for aerial taxi service


My colleague Josh says, "As a prior VTOL pilot, I’m surprised that they're showing fixed-pitch rotors—meaning they’re going to try to control it by speeding up or slowing down the rotors. That works on drones because they're small. For something this big, you would end up with much larger, heavier motors than you'd otherwise need. Variable-pitch adds mechanical complexity, but it's a long-solved problem in helicopters. I'd still love to fly it."
