Toroidal Propellers - Magic or Myth

[Kristina Fowler]

Anyone have experience with Toroidal Propellers on a drone? Interesting concept for noise reduction and battery life. Fools' errand? Thanks...

Thanks for sharing. Not sure why you would say myth or fools errand when it’s obviously proven science.
It’s just a matter of time before somebody comes out with the version for drones. Hopefully somebody out there can try printing them. The sound is a real problem, and if it cuts that I’d buy them in a heartbeat.
