I am 100% you saw this in the news a couples of weeks ago.
I was blown away by the design until I read a comment that linked to this:
This is NC one V2
In my personal opinion, I think that the bolt holding the motor should be replace by something else. There is 4 of them, it’s heavy! When I worked in Hong Kong, on RC toys helicopters they use to remove every single grams of weight they could! 1 grams can change everything on very small craft like this one. I would of tried a press fit plastic adapter. The plastic adapter clips in the PCB and the motors is the press fit.
Look at that sexy components layout! Very well done!
