This FPV racing drone has no less than 64 propeller blades

A video has surfaced on YouTube of a test flight with an FPV racing drone that has no fewer than 64 propeller blades. Two props with eight blades each were mounted on each motor for this purpose. The video was posted without further explanation by one quadmovr. It is therefore not entirely clear how the modification was carried out exactly, but the minimal noise production is striking.

Most FPV racing drones have four motors with three propeller blades each, so twelve blades in total. That simply delivers the best performance when it comes to speed and maneuverability. The disadvantage is the enormous noise that such drones produce, as a result of the high speeds the motors make. Not many people are really happy with the characteristic whine.

That is why this experimental 64-blade FPV drone is very interesting. It seems that much fewer revs are needed to develop enough thrust.

Judging from the audio recording of the video below, the sound the drone makes is more like a small low-revving jet engine than a pair of screeching propellers.

Two props per motor

Incidentally, it appears that quadmovr has mounted two propellers with eight blades each (so sixteen blades per motor) per motor. To this end, he probably mounted modified engines with longer axles. In any case, a special experiment, which may one day lead to quieter racing drones.
