My P3S makes a squealing sound as it flies.

Is some kind of lubrication of the motors required?

Thanks!

No lubrication is recommended or required. Probably a normal sound, but you could post a audio clip here if you'd like.

I have heard several Phantoms in flight. A couple I would consider have a higher pitch sound. Squealing.

I know one for sure has taken severe crashes. Not mine lol

For what it is worth.

Good luck
