I wonder what it would sound like if they went to a higher blood count on the props. For some reason they don’t seem to have garnered much attention yet, but eight blade props are extremely quiet relative to the smaller prop counts.

Here’s example comparing a typical 2 (or 3) blade 5” prop to an 8 blade on a drone. The 8 blade is smaller, 3” i believe, with similar performance but a major difference in sound.

Here’s another one with two 8’s stacked on each motor.

Also for all the time spent developing the aircraft and the importance that perception plays in selling it you would think they might have put a little more effort in figuring out how to efficiently load it. That was torture watching haha.

(wtf Apple, the ’haha’ in my last sentence autocorrected to ‘gays’?!? I wonder what i haven’t caught)

> higher blood count

Made me chuckle :)

lol I’m leaving it
A lot of the drag on a prop comes from the tip of the blade.

More blades means more drag.

I think from my limited knowledge of propellers that more blades is less efficient, so it would lower flight time.
Propeller efficiency drops off with increasing blade count.
