Hello,

I am having coil whine type noise for a while and when I try to look closely, it looks like the drone is vibrating slightly. Although, I am not sure if that was always the case.

I am attaching video with audio and DAT files here: https://drive.google.com/drive/u ... AI3s4frRjXU40t9-5ZP

Note: I have always had Rfront and Lback spin slightly faster than the other wings but I did not notice this sound before. Also, no issues when flying.

Is this a motor issue or props? Should I try to get this RMAd since I have around 2 months of warranty left.

Also, no errors from the app.

Hi there, from the video, there is no obvious abnormality. Since there is no error message prompt in your app, you may continue to observe. If you are still worried about it, please contact our support team via support@dji.com to open a case and send it in for a thorough diagnosis. Thanks.
