I am a novice and not good at analysis.I hope someone can help me.Thanks.
I have a problem of unstable flying quadcopter with PX4.
https://logs.px4.io/plot_app?log=63db6fd4-5f5a-482d-9c03-6f001a4a8277
EKF2_IMU_POS_X=0
EKF2_IMU_POS_Y=0
EKF2_IMU_POS_Z=0
It probably needs some tuning. I would try to carefully do a little hop close above ground in Stabilized mode first, before you use position or autonomous modes.
Also, read up on tuning here: Multicopter PID Tuning Guide (Manual/Advanced) | PX4 User Guide
