Filter online review, review 5in hexacopter

Totally understand, it was just temp so its better I remove it now than later

Here is the bin after the changes to the filter made. It appears that the noise is gone now.

Filter looks good. Keep going!

Was that with or without the antenna?

that was without the antenna. Is there anything else you suggest I do with the current filter settings? Should I just keep moving through the tuning process?

I’d call the filter done. Keep moving on the process. I looked at the rate outputs and they looked good too.

Just keep in mind that if you add some of that gear on again later you might want to check back and make sure it’s not causing trouble.

@dkemxr @Allister
Thank you for helping me with this, I think I can do the next one. I really appreciate it.
Here are my current rates just for information.

I am using the 5in master air screw props on this build. I have really liked all that I have used from them so far.

As I am going through the PID tuning guide by Chris, he is talking about tuning the I gain.
But from what I remember reading here “I” should match “P”. Did I miss something?

Around 23:42

Its probably because his background is betaflight. Generally you don’t need to tune the I-gain on ArduPilot like you would on betaflight because we have an angle controller.

@andyp1per understood. Just trying to make sure I’m doing everything right.

@dkemxr @Allister I got to the PID tuning point, this is after I completed the magfit and quick tune.

Judging from the information I have read and watched the tune looks pretty good but would like a 2nd look.
This is before the autotune…

This is after the autotune

Here is a bin of after auto tune in stabilize mode

There still seems to be some noise around the roll axis, and that ~60Hz bump is back with a vengeance.

I think a static notch might be the answer here. Is the antenna back on?

I didn’t put the antenna back on, I think I may have found the culprit. Might have been my power brick laying on the frame. Ill test it out and see. Any suggestions on the roll axis?

It was not the power brick. Guess Ill be configing a static notch

I dropped the D term on roll and it seemed to drop the 60hz vibration. Static notch didn’t seem to help. Maybe I am doing it wrong though

Try something like this:

I am struggling to get rid of an oscilliation, it seems to show up oddly at the end.

I started dropping my PID values and it doesnt seem to go away.

I dropped this to half and it doesnt seem to help…

Maybe this value is to high?? I have read a bunch but still don’t seem to have a good understanding of its effects.

@dkemxr @Allister Looks like after reducing my pids in the roll axis I was able to remove that 56hz noise almost completely without adding a static notch.

This is the PID results that I ended up,
