Phantom 4 Pro Clunking Noise at Start-Up

[Don Barar]

Hi All,

I had the occasion of starting the motors on my Phantom 4 Pro without the propellers on. I heard two rapid clunking sounds. I have upload a YouTube Video. Can anyone tell me if this is normal behavior?

Thank you in advance.

My Phantoms make that sound too. They also make that sound when the props are attached (just sounds a bit different).
