Sounds normal,the clicking noise you can hear sometimes is the mechanical sonar clicking away,gimble speed can be adjusted if to fast or to slow,,,vps is the sonar,,vision positioning system.......ps some reason the 2nd vid wont play but 1st and 3rd play

If you want an idea of whether the camera has ever been removed, look at all the screws that hold it to the body. From the factory, the pocket in the head of one of those screws would be filled with an epoxy. That filled pocket won’t allow a driver tool to remove the screw unless you remove the material from the pocket.

Sounds like the internal fan. Some are a little louder than others. Have 3 its normal.

It's hard to judge the loudness of the grinding sound; but no, my P4P does not sound like that. I've resolved to never buy drones on eBay. I bought 2 P4P's on eBay, both with issues. One had a crooked gimbal and the other was unable to fly straight. In my opinion, eBay is the dumping ground for drones that owners don't want to or can't afford to repair.

I have a few p4p’s and I’ve not heard that one.
