I confess to being an old school helicopter guy and find the battery-electric drones swarming the sky quite irksome.
However we must give those enthusiastic drone-youth some credit .... here is a prototype battery-electric they built to carry a passenger .... they are not hindered by anything ... probably no one told them it wouldn't work so they just went ahead and did it. Filmed at an old Zeppelin hangar in Germany I think
It is an 18 minute video .... and at 15:00 flies outdoors with a lightweight dummy .
Will be interesting to see if it will actually carry a passenger , and of course battery life will likely be under 30 minutes and not very practical as far as helicopters go.
Have to give these fellows some admiration ... not only that ... they are already self-trained to fly it by remote control ... I think I am jealous .... haaaa !!! ... and I doubt they have a multi-million dollar helicopter engineering department backing them .... they are more like video-game enthusiasts.
Anyway , it gives some credence to using several small electric motors with plastic propellers like the Bell 429 experiment.
