My P3A is MUCH louder in flight than my P1.

How's the P4 noise level? Is it quieter than the P3P and P3A ?

If I want to fly over a neighborhood I choose the P1 because at 75ft I can BARELY hear it.    I can hear the P3 up to abut 250Ft

Not "spying " on anyone...so no need to go there......

Just thinking in terms of enjoying the hobby without paranoid people getting all crazy.    The P1 is MUCH harder to hear so less people would notice it in the air probably.

I wish my P3A was quieter.   That thing is downright noisy comparatively speaking.  Anyone found any quieter blads that don't kill flight time?

Get the M600, that thing is amazingly quiet

Yeah and $5k too. Nice ken

For my needs, the P1 is a far better choice than the M600
It would be like me buying a Nikon D800......so I can take 640 x 480 photos.
