Apparently it works on centrifugal force versus wind resistance.
Seems like it will do less damage in case of accidental contact (I won't test that theory). Probably less damage to the propellers when striking an object. And maybe more, plus the ability to fold the drone into a more compact case.
I wonder how straight the propellers stick out when it's in flight. High-
speed photography might be able to tell that, with a stationary drone.
Another neat thing... The controller communicates with the drone very well.
It can be controlled from inside a house (while looking out the window to
keep an eye on the drone, per regulations) with smooth video feedback. The Mavic Air with its Wi-Fi is not so good (all Wi-Fi sucks for FPV). Apparently the $1000 DJI FPV drone has even better communications technology. The Mini
2's communication method is called "OcuSync 2.0".
