Hey Everyone! I just got my DJI Phantom 4 and it's amazing! I had a Phantom 3 Standard for a while and finally decided to upgrade. One questions though, I noticed a very slight buzzing sound when the device is turned on. It's a combination of buzzing and humming and is very low, but definitely something I can hear when I'm next to it. I took a video and for some reason it sounds WAY louder on video, but this is what I'm hearing (It's very low so I don't know why it sounds so loud in the video). I just want to know is this normal or should I return it? It may be the sensors - if anyone else could post a video that would be great. Thanks!
