Title: Opinion of my PID's

What do you guys think? Seem normal? I know normal is relative here.

Your max rate limit should be equal to or higher than your rate mode response numbers.

"I" gain is most generally double or more than the P gain on both roll and pitch.

Yaw I gain is also "too low". It is usually double or more than the P for yaw as well.

But if it flys nice, hey don't listen to me.  Numbers just look odd, but if that's the numbers txpid gave and it flys fine go with it.

main question: how did you achieve those values. The P  values look reasonable, but all the I values look to low. You can get a reasonable good tuning by using the Easytune feature. I think the wiki describes how to use that.

I.have only one available knob and not the three that are recommended for txpid. So i would slightly change a value and fly than change a value fly again and so on. It was a PITA but it seems to fly nice for me. I can tell it still needs work but it is a vast improvement from what it was.

You can use nine pots if you have extra channels and a small collection of pots to make a panel for them. But only one is required.
