Wobble on sudden movements

Only one IMU is being recognized:
INS_ACC_ID,1442050 (MPU9250)
INS_ACC2_ID,0
INS_ACC3_ID,0

Pitch and Roll Tuning is bad:


I don’t see much evidence of PID tuning just a reduction in the Rate P&I values. Update to current Stable firmware and review the Dynamic Notch configuration then run Auto Tune.
Set these as per the Wiki also:
PSC_ACCZ_I
PSC_ACCZ_P

What pıd tuning settings would you recommend I change manually before autotune?

You should read this article before initial tuning.
https://ardupilot.org/copter/docs/setting-up-for-tuning.html#setting-up-for-tuning

I already started by taking these parameters as a reference. Are there any parameters you suggest I change?


What could be the reason for this apparent shift between desroll and roll?

I didn’t manage to do this for navio 2 i don’t know how

@Resny73 you tried to autotune the drone? or working with the very Default PIDs???

I’m a little hesitant to try autotune because my drone is too big. I’m flying with the default parameters right now, but it does some wobble. I flew even in auto mode, but there is still some wobble

@RES1 use given links for refrence

and Automatic Tuning with AUTOTUNE — Plane documentation

we autotuned this drone. is your drone bigger than this?

first of all thanks for your answer. My drone is slightly bigger than that but my main reservation is that I don’t trust my pid settings. and not relying on the risk of failing and dropping the auto-tuning that I come across a lot while researching on the forums.

These are the videos of the old version but I’m uploading it for you to see the size.

You seem to be struggling with some very basic tasks. While I don’t want to discourage you too much, I strongly recommend building, tuning, and flying a smaller quadcopter (10” or less props) before attempting to fly this large craft any more. I’d hate to see you hurt yourself or someone else through a lack of knowledge or experience.

Man you would have hard time autuning that as this is not a small drone and you don’t have a rig like

as there is no other way of autotuning PIDs just like that without flying the Drone.
hope you find PID values which matches your drone.

I understand and respect your concern. However, I already fly a drone of the size you mentioned with nice pids. However, as the drone grows, things get harder and this big drone could not show the same performance. (You can be sure that I took the necessary safety precautions)

I am thinking of such a rig. However, my thought was a system that can move in all axes and can be connected under the drone. It was good to see this video, thank you very much.

I found this slightly dated post on updating the Navio2. I think it should still be relevant, and you could simply replace any reference to ArduPlane with ArduCopter.

Thank you very much for your help. I will look into it.

Let me know if you need pid for this drone from 0-20kg payload

I am interested in comparing pids for large, heavy load copters. I am working on a fire extinguisher drone ATM and I am still scared to start auto tuning :smiley:


Then I would suggest that you create a new thread post with the questions you have. This “wobble on sudden movements” thread has been worked over.
