  • Hi,

    changed the Roll P Gain to 0,1 - works fine for me!


  • I battled such a problem for a couple of months.  Turns out, it was due to vibration wreaking havoc with my Pixhawk accelerometers and/or gyros.  Two things I did to reduce vibration.  One, I replaced the cheap Gemfan CF props (1652).......even when you think you have them perfectly balanced.....doesn't mean they are dynamically balanced.  I replaced them with KDE 15.5x5.3 CF blades.  Also, I did a better job of isolating the Pixhawk with softer mounting foam and a framed mount with bobbins (anti-vibration balls).  There were a few other measures I took to reduce vibration but I think you get the picture.  Good luck.


  • It can also be caused by plastic propellers. Try carbon fiber ones. They are far stiffer. That can make a huge difference.


  • The Roll P Gain is too high.

    Try Inflight Tuning

  • Hi, IMO you have an Pid setup problem, try down Pid rate , I hope I can explain it with my poor english.
