You can stack Emrax motors on a shaft. Also, the technology scales up in diameter. Not that you really want _that_ large props necessarily, if you can get away

You can stack Emrax motors on a shaft. Also, the technology scales up in diameter. Not that you really want _that_ large props necessarily, if you can get away with smaller ones. This combination should be enough, I guess. Edit: I think I met the guy behind these. But I'm not sure, for lack of having asked for the name of the company. I certainly have seen a prototype that could have been the 348.
