It could be that the poor Phantom is just having a tough time trying to lock onto the grass below it.
Try turning the VPS off or fly up beyond VPS range (10 metres) and see if that makes a difference.
The VPS needs a surface with a clear pattern or texture to lock on to.
Grass, carpet, concrete etc gives it a hard time.
Unfortunately that's definitely not the case. It behaves the same, no matter at what altitude I'm hovering at. This time I kept it low so I could film this.
Also my Mavic Pro never behaved like this. Nor did the P4 that I sent to DJI for replacement
Have the gain/expo settings been set to something aggressive?
My
P4P is smooth as silk, even close to the ground so something is not right with yours.
Well, my assumption is that of course it should be smooth and also without this horrible sound - which makes me fear for bearings.
Unfortunately you lost me with the gain/expo question... what have they got to do with the drone just hovering without any input from me?
That just doesn't sound right. One of the motors not spinning freely?
Besides jerky movement (as if it's fighting with a non-existent wind) and the metallic sound there's one more thing. After just 5 minutes of flight the two black motors (CW, front left, back right) are both pretty hot while the other CCW pair are barely lukewarm.
Now, if you watch this video carefully (especially on 4K full screen) then you can see it's doing this twitching along the same axis (ie back right or front left or both) suddenly change speed, causing the drone to suddenly do a tiny tilt after which it automatically compensates. That can be head even from the noize. And oh boy, this sound is almost as loud as the props themselves.
Well, I guess I got enough opinions to conclude that the drone DJI sent to me is dangerous to fly. Here we go again, DJI warranty this time...
To mod: Thank you for censoring me for using the word "hell" - I must have committed a heinous crime by summarising my DJI customer service experience with this word - there is no place for human emotions on the internet - even after you've been repeatedly lied to and jerked around by DJI - only to get a drone which is mostly suitable only for mocking their Care and Care Refresh plans and the given promises. I should've taken more time to compose myself before making this video 7AM this morning.
