It's good to hear that someone else also has that experience.
So, did you have it out of the box ? How long you fly with that sound ? Did you try to fixed that ?

As I have said - many do have the high pitched whistle and it is not a problem. Nor does it indicate worn or faulty bearings.
They are perfectly safe to fly and a large proportion of DJI aircraft exhibit this noise.
