I have just bought a DJI Avata and out of the box i have noticed what sounds to be bearing noise coming from the front motor when spinning it by hand. I have returned it and got a new one that has the exact same noise from the same motor. It just dosent sound right. See YouTube link for video
Hi, there. We are sorry for the inconvenience caused.
You can try to start the motor on the ground and check whether there is an obvious abnormal sound.
If there is still one, you can send your drone back for further check. Here is the link: https://repair.dji.com/repair/index?site=brandsite&from=nav
