Aggresive oscillations in postion hold mode

Hello ,
I am using Tarot 650 sports frame with Pixhawk 4 running on px4 v1.9.0. I tried using position mode, It showed periodic aggressive oscillation as if one motor was shutting down and again starting.
The stabilized flight mode is working fine,but as soon as it is set in position or mission mode it shows the same behavior, the same pixhawk works fine on smaller drone.
Here is the log file

Please help
Thanks

I am using S500 frame and i am facing the same problem, when i change the mode to hold mode, its starts vibrating violently.

I think I have found the solution to this problem ,

  1. Check if your drone is 3D locked

  2. Decrease your hover throttle to 30% in tuning .

  3. Check Hold flight mode , if it is holding position properly then point no 2 will solve the problem in position hold mode.

  4. I would also recommend you to decrease your p roll and pitch rate in pid tuning to increase stability

Decrease your hover throttle to 30% in tuning .

That is right, you have in-air land detection due to misconfigured hover throttle. From the log it looks like your hover throttle is around 24%.
