World`s quietest Race Drone? NEW 75mm Whoop | 802 19000kV Motors | Gemfan 1608-3 Propellers

Some Testflights with my newer 75mm Ultra Light Whoop. With the Gemfan 1608-3 I'm very happy for that whoop. A little less pitch would be even better, but unfortunately that doesn't exist. I also tested HQ Prop 51mm Bi-Blades shortened to 40mm, which have a little less pitch and worked very well. Very good throttle control/mechanical resolution on a small indoor racetrack. But somehow I like Tri-Blade better because they are smoother in orbits (eg also in ladder gates) and quieter. A very leightweight gemfan 1606-3 or 1607-3 would probably be ideal.
