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
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.
I am not sure what to look, but I can see 4 things that are not ideal: - RC Pitch 2100 - Power not set - What is causing those discontinuities on the graph? - I2C errors though 0, is red? Check IMU cable, or it could be some other IMU problem
