Hi. I’m doing a flight test while making a copter and I think the vibration is a little bad. In particular, there are vibrations in loiter mode and no vibrations in althold mode. Please check why.
Hello @zlzzlz3003 welcome to the community,
That is typical of poor/incorrect tuning.
Follow MethodicConfigurator/QUICKSTART.md at master · ArduPilot/MethodicConfigurator · GitHub to fix it quickly
I used the program. There is no vibration at all in alt hold mode. I’d like to know why
Post a .zip file with the contents of the vehicle configuration directory created by the ArduPilot Methodic configurator software. Then we can see what went wrong.
There appear to be vibrations in all modes.

The vibe keeps vibrating, so I’m going to install damping, etc. Should I change the notch setting like that and test it?
try the notch filter before installing damping. Damping should be a last resort because it can cause it’s own problems.
Thank you. I will apply the notch filter provided by Allister and test the flight and let you know if there is no problem.
Hi. Could you please analyze the zip file? I’m still a beginner.
After modifying the filter, I conducted a flight test. The vibration has definitely decreased, but the gyro level is weird and there is still vibration in the vibes. I would appreciate it if you could check

IMU temperature compensation was OK.
I corrected some of the stuff

But you need to update EVERY SINGLE reason changed field, not just some of them.
And you need to provide URLs for the products you use in the component editor window.
Update to the latest Ardupilot Methodic Configurator version 0.9.3
Thank you, based on this, I’ll try again from number 04. And I’ve added a link!

The filter looks much better now and the vibrations aren’t the worst. They could be better though.
Make sure all the wires are secure and not flopping around. Nothing should be pulling tight on the flight controller. Is the plate the flight controller is mounted on rigid? Does the plate have any flex?
Lots of vibration peaks on the z-axis. So check that all the props are in good shape. No damaged tips or bent blades. Look to see that all the blades track well.
There is still some work to be done on the pitch tune. Follow the instructions in the methodic configurator very closely.
