    I noticed this immediately when I started flying my new P4, and landed right away to see if something was loose it. Nothing appears to be, but I get this metallic clanging noise when I fly it.

    I happened on a YouTube video of somebody filming his first P4 flight, and lo and behold, roughly the same sound. It sounds worrying, but maybe it's normal... anyone else?

    I didn't notice this when flying mine. Got a link to that video?

    Here it is:

    Go to about 2:30 where he first takes off. You hear this pinging metallic rattle. It's a little less noticeable on this vid but it's the same tone I'm hearing.

    I don't hear anything odd. Mine sounds exactly like that.

    Is it the wobble sound you hear on take off - like something spinning out of balance?

    If so, check your props. That could be the sound you're hearing..

    The only weird noise I am hearing on mine is from the gimble. It has a squeak noise when it moves at certain points.

    It's the ringing, rattling, high-pitched sound you hear at take off there, and also throughout the flight (at least the start where the mic on the ground is still picking up the P4 sound).

    It may not be a material problem with my P4 since I also hear it on this vid, but it still gives me an uneasy feeling. I can hear it from 500' in the air.

    For some of the film work I've done with the P3P, being as quiet as possible has been critical to success. (nothing salacious nor illegal)

    So, apart from having me wondering whether something's about to spin off the craft, the noise level is something I'm possibly hyper-sensitive to.

    I'll switch out the blades and keep tinkering to see if I can isolate the source of it.

    Dude, I accidently ran in to your vlogs traveling to South Africa with your wife! I love love love your videos.

    This is a man that understands what it's all about. You looked like you we're having so much fun, meeting people.

    The P4 ladies and gentleman is a prosumer item and he uses it as it should.

    LOVE your vlog. So much fun. Watched about 10 of them in a row last week.

    ***oops, just realized someone was posting his vid.

    microphones CANNOT be trusted anywhere near the bird. The interference makes a very odd noise that isn't really there.

    Yeah, but that sound is there on my P4 exactly as it is on his in the vid. Isn't there on my P3P at all.

    I do get the sound. I understand what you mean. Don't know why.

    Add me to the list. Don't know if I have to worry or not.

    yes, that is the question, do we need to worry ..or this is just a normal operation noise. I did not have this noise in my P3P.

    y had to watch the video several times.
    I did hear a sound sort of like the ringing of a bell.
    herd this when it took off and part way through the flight and herd it when it landed too.
    mine does not do that.

    The high frequency sound? I have that too and from flying other quads I find it normal. Can someone attest to otherwise?
