Wow, that's incredible. As in incredibly crazy... Looks like a flying coffin to me. Kind of reminds me of this from a few years ago:
Great ideas, bad implementation in my opinion.
Actually I'm working on something similar, but taking a more sane approach (I hope - it's hard to rationalize sometimes) of scaling up by scaling out. I.e. adding more conventional / commercially available electric motors rather than fewer higher-power motors. This leads to safety through redundancy among other things.
Still trying to get my first scaled-down prototype (to demonstrate redundant power & control systems, etc) flying though. Now having LP FC issues getting motor controls working when count > 6.
But sorry, I didn't mean to hijack this thread.
