Mavic Pro motor whine

[jdyck]

Anyone experience a whining sound from the motor(s) and what does it mean? Just noticed it today after many flights. Wondering if it is something I should be concerned about. Don't want to lose my Mavic. Comments please.

Could be a bearing is going bad in one of the motors, have they done lots of hours?

Likely about 50 hrs (will check). A little cool this morning near freezing so possibly that but not sure. Don't want to lose it as I fly over water a lot. I would expect the unit to last longer than that. Whats new motors worth? Do I have to purchase from DJI?

Checked it again today. Temperature about 7C and could barely here the whine. Not sure if simply missed it previously or if in fact the whine is a new developing issue.

Check your propellers because if one has a small damaged spot it can make a new sound
