Hello, I build large quadcopter drone with 18inch prop, when I check my log there is very very large discrepancy between desire and actual yaw, what might be the problem? oh while on it how about my roll and pitch PID? is it good enough?
here is my log for several test hover
Log - Google Drive
Here is one example
Identify one (1) log for review.

Sorry, I don’t get it, what is one (1)?
Pick one log file to look at. We’re all doing this in our free time so it’s unlikely anyone will sift through a bunch of different log files.

I see, I have selected one and deleted the other on that google drive link, thank you in advance
I would describe this tune as unfinished. There is a lot of noise on all three axis and there is room for improvement.
Vibrations are higher than desired. You should look to find a source of the problem and address it. Mostly X, and some Y, so I’d look to the airframe and make sure all is secure and that no wires are bouncing on the flight controller. If you have a GPS on a mast make sure it is secure.
Filters are good, but I have a habit of reducing the filters even more. Here’s my suggestion based on your current filter settings:
With those cleaned up I would consider running the quiktune script again and then running auto-tune.
Thank you for the answer, I will try those filter and run quiktune script again, I add landing gear and then my vibration went up will check on those for the vibration problem
The landing gear is the problem. It vibrates.
