Welcome to the comunity

Thanks a lot. I`m still waiting the help

All I see is Output Oscillation, probably because the vertical acceleration controller gains are at default. The ATC_ANG pitch/roll P gains are too low (for any craft). No current logging and old firmware. Are the Motor Ranges set correctly?

Hello, i am not so sure about me, so tell me your opinion about everything. Thanks a lot

We have motors X9 Plus. As i know all ranges are correct

Update to the latest Stable version of firmware.
Set the ATC_ANG_PIT/RLL_P back to default.
Re-run the Initial Tune Parameters. Setup>Mandatory hardware>Initial Tune Parameters
You Rate filters are way too low but the above will fix that.
The motor ranges do not look right with a MOT_SPIN_MIN at 20% throttle.
The vertical acceleration controller gains are at default. Set them based on hover throttle.
Setup current logging.
Follow an Arducopter tuning process. Tuning Process Instructions

Or perhaps reset all to default and start over.

Thank you my deer friend. Can you tel exatly what you meen with motor ranges and Mot_spin_min?

Please read the Tuning process instructions that Dave posted. It’s all explained there.

And after that if you still have questions and want to make sure you do the entire process in an assisted, proven and safe way, use ArduPilot methodic configurator software

That software was designed for the single purpose of safely configure ArduPilot vehicles without forgetting any required steps.
