Looks like the yaw is somehow wrongly tuned, maybe basic settings, maybe PID. could also be broken motor. Does it work on ground she operating it in hand?

there is a strange railing sound, would be good to identify and get rid of it.

After almost a month of testing, twisting, de-soldering, re-soldering, tightening bolts, de-installing, reinstalling, downgrading, upgrading, lots of frustration, getting crazy, etc, think I almost have it tuned, but not sure if issue is with roll or pitch.



Now I'm using 2.40b7,
same 8 bit DYS Smart 3 axis gimbal on Phantom 2,
No ND filter

R 13 0.22 18 65 50 14
P 12 0.29 10 60 50 14
Y 35 0 35 105 50 14
No limit -x y

Any advice?

Thank you Garug,

1. Checked new propellers before installation, came factory balanced.
2. Checked, ok.
3. Checked, ok.

One detail I found today is that I inverted one arm of gimbal, that way is easier to connect usb/hdmi cable and take gimbal or memory card out, but sensor is a little away from lens, so moved sensor closer to lens, test pending, rainy day today, hope tomorrow will test.

One question I have is, is this graphic ok? should I increase or decrease I parameter? or any other?
I'm using it as a base for the other axis too.
