About the man carrying multi-rotor designed and flown by Catalin Alexandru Duru

A few days ago, I saw on the net a quite interesting multi-rotor capable to carry a man 275.9 m at a height of 4-5 m.

I have found three pictures and two videos (see attached) showing C. A. Duru's 8-rotor helicopter in the lab and flying.
However, I have not identified too many technical details regarding this hovering machine.

Maybe you can infer from the images what:
- motors
- batteries
- propellers
etc.
C. A. Duru uses?

I am interested in finding out how much such a hover-board might cost and where I can find the necessary components.

Awesome!!! And it looks homemade which is inspiring.

I want to make one!

I was sugestted to use eight U11 T-Motor (see: http://www.rctigermotor.com/html/2013/Power-Type_0928/93.html).
Tested at 50 V with a 26*8.5CF T-MOTOR propeller, an U11 lifts 12.42 kg. So, eight U11 units will be enough to hover 99.36 kg drawing 379.2 A (379.2 A x 50 V = 18.96 kW) in total.

A group of eight U11, which costs n0 less than $350 x 8 = $2800, looks a good candidate for C. A. Duru's flying platform. However, a 50 V, 379.2 A battery is needed.
