Hello
Just bought a brand new DJI Phantom 3 Advanced. All good but when I start the motors I hear a strange sound and I think that is a problem with this DJI Phantom 3 Advanced. Please watch the video and listen to the sound and tell me if you know what make that sound. The strange sound (heard/soundes better) when I accelerate slowly the motors at 0:22, 0:46 and other parts in the video. Here is the the video:  

Thanks and have a nice day !

Have you flown it yet or just let it idle up on your table?

The motors have a beautiful sound
There's a disturbing brrrrtttrrttrr sound but that started before the motors?
Hope that one comes from interference and not your drone..
Remember all motors have a break in period!

I hear two sounds...one is very loud and sounds like some kind of interference.   I'm guessing that one is not related to the Phantom.
The other noise I hear sounds like a scraping noise related to the spinning of the motors / props.
Maybe it's a resonance vibration?

Can you try again maybe with a differnt recording device because if the loud noise I hear is your Phantom, it needs to go back immediately.

Sorry but I don't understand what are you want to say the motors have a brake in period. You mean the motor is not used for a long time ? But its must sound fine without that buzzz when I accelerate that loud sound is interferences

No, I mean all brand new motors have a harder sound until the parts have (language barrier) adjusted to each other.
I think your motors sounds great.

The first sound "fast clicking that OP couldn't hear" is the VPS working.

...and by that, I mean the ultrasonic emitter and receiver part of the VPS module.

...and if I turn off the VPS why that sound persist and heard when I accelerate because when the motor run in idle I don't hear the sound. If that sound is caused by the VPS why I heard it, because that is ultrasonic who I can't heard normaly.

I was saying the loud sound you said you couldn't hear was the ultrasonic part of the VPS module. I think the sound you are hearing from the motors will go with time. I wouldn't advise running your motors without props on for too long either. The motors are designed to be run in with some resistance i.e with props mounted...

Nothing wrong with the motors, they are not loaded ( no props) and will rev up much quicker than a loaded motor. Normally it is not recommended to rev unloaded motors to full rpm, they sound fine and yes the clicking sound is the VPS.

Motors sound normal to me.  Popping is likely VPS.  I hear it in almost every video I watch of people demonstrating in close proximity of their Phantom.
