This appeared on YouTube two years ago under Heavy Lift Drone Project, and there is invaluable information on the wiring emanating from T-motor's ESCs, which like much else from China comes without documentation of any sort. The project is significant in two different ways, in that for one thing its demonstrates how the most obvious way to construct a very big drone is merely to scale up a smaller (which is not necessarily ideal); and the fact that the videos dry up prior to us ever seeing it flying. Tough game, eVTOL, and best avoided. Except like much else in life, it's discovered after the fact.
