High pitched whistle

[Newbieguy]

After about 2.5 hours on a P3S I've developed a loud high pitched whistle. It's not the props, I've checked for a hot motor, I can't see any debris in the motors. All the motors spin evenly. I'm afraid I have a bearing problem. Any comments? The video below is not my drone but it makes the exact sound.

I get that, too though maybe not as loud. I think it's normal.

Some whistling is common. A bearing problem would cause that motor to feel a bit hotter than others.
So whistling alone is not a cause for concern. Keep monitoring post-flight motors temps for confidence all is OK.

Thanks for the input. Much appreciated. What's left of Irma is here in Kentucky. We have about 16 to 20 MPH ground wind. I'm going to keep her in today. I will report back. Thanks again
