I have just gotten my Phantom 4 Advanced. I turned it on, and immediately noticed a loud buzzing sound coming from the gimble of the aircraft. It also vibrates slightly, and the gimbal gets pretty warm after some time. I was very confused, and did not know what to do as this was my first drone. I checked to see if the firmware was all up-to-date, which it was. I looked around on the internet to see if I could find any fixes for this, but I could not, even though some others had a similar problem.
I would appreciate it very much if anyone knew a fix for this, or if I should send it back to my seller.

Please reply and ask if I missed any details and you are willing to help!
Thank you!

I found a video showing exactly what happens:

There is a beta firmware that resolve that....ask to any admin

Ok guys I found the issue. After some looking around on the internet and further inspection of the aircraft, I figured out that the noise comes from the fan in the aircraft. It seems as if the fan is vibrating against the body of the aircraft, which seems to be a design failure. I hope they fix this on their next model.
Good luck guys!

hi. Can i know what is the numbers of version beta? I still thinking of p4 pro or p4 adv. I felt p4 adv is more cheaper than pro but no 5.8ghz. i think it not matter. As long as i want is 4k 60fps only

Hi, there will be a small word "Beta" if it is the beta firmware. Yeah, sometimes 5.8GHz might avoid some interference in the same condition when compare Phantom 4 Pro with Phantom 4 Adv, coz many WiFis are using 2.4GHz. It depends on your personal needs.  And both of them support 4K 60fps at H.264, no worries.
