I'm a bit skeptical of the eHang 184, built by a Chinese company that's built toys and commercial 10-kg-drones - it has 8 props, namely 1 coaxial twin prop (presumably counter-rotating) at every corner. Does not look hugely redundant to me, plus they're conveniently located to break legs while on the ground (or heads during take-off/landing).

The Volocopter has had manned and unmanned test flights since last year, has 18 rotors in a rotor plane well above your head, can fly with 4 rotors inoperative, has a ballistic rescue chute, and apparently good initial feedback from the regulator.

(Disclaimer: I've invested 1000 EUR in the Volocopter via crowdfunding, so I might be hopelessly biased.)
