Hello

I have seen that there are quite a few development projects around our globe on optimizing propellers for efficiency and noise, and there is a lot of information to be found.

Came across this on youtube yesterday, but can't find any information other than this from a small clip in this youtube video.



Does anyone have any more information, whether it's real or just hype?

Interesting video.  I always use Master AirScrew props on all my drones.  They seem to be well designed, a bit quieter and more efficient.  

Wow! I love MR vids
