    Hey guys,

    I have seen some people asking about the 'humming noise' from the Gimbal at rest - and others replying that it's normal:

    viewtopic.php?f=26&t=29038&p=266839&hilit=noise#p266839

    However I am a bit concerned and took a video, just to make sure we're referring to the same noise. Could you please take a look and let me know if it's normal?

    Other than that it's performing very well. Super pleased with the video.

    Thanks in advance. Jack.

    Mine does exactly the same thing only much worse. I can even feel my phone vibrate and if i put my hand on the camera. It can't be good for image quality.

    Mine did the exact same thing. Could hear it on video at rest as well. I was told by dealer it was normal. Definitely not an issue in the air but it is annoying.

    Like all of DJI products, I think there is some variance in how loud they are, but they all seem to do it to a degree. You may luck out with a different one that is quieter, but I'd just fly.

    jack are you familiar with the concept of 'neutral balance' and confirmed that your gimbal/gopro are neutrally balanced correctly? If they are not, that could be why the motors are running/whining all the time... my H3-3D did it with my Hero 3+ until I balanced it properly. check out this post I just made, yours might not be imbalanced on the same axis but the principle is the same

    Hey QYV, apologies for the delayed response. Yes, even when I balance it the noise remains. I tried doing all the calibrations etc. when balanced. Didn't make a difference.

    I also contacted the dealer, who was happy to bring it to DJI for me. However, it's just too much of a risk and hassle to do it when the video quality is unaffected. I just hope the noise isn't a symptom of a serious problem.
