Volocopter has been tentatively demonstrating its multi-rotor urban air mobility aircraft for a couple of years, but this year, it showed up and flew at Oshkosh for the first time. AVweb talked to Florian Reuter about where Volocopter development stands.
Will it auto rotate?
Short answer: No. But multiple batteries and multiple motors would offer some options for redundancy as long as there is enough margin in the overall power/thrust budget.
Why not go hybrid?
