I was wondering if i could get some help on PID tuning. Ive been reading up on it and I am still lost. I was trying to use Gtune but it wont save the settings after flights. I followed the directions according to clean flight. Any help would be great . Thank you

I will have a look at the log tonight.
About G tune, I think when you finish, you need to turn g tune off, then turn it back on again to save it....

I could be wrong, but I thought G-Tune only works in Rate mode and only adjusts the P's anyways.

This G-tune, is it Autotune or something else? Because I'm also having hard time with tuning pid's

The balckbox doesn't tell much... you can't just hover, you need to do some movements...

I did the disarm save after each flight. I have some movement but the file was to big to post . I had cut some of it out . I can try to post another recording

 Your right ! 
"The implementation you have here is quite different and just for adjusting the P values of ROLL/PITCH/YAW in Acro mode. When flying in Acro mode (yaw tune in other modes possible as well - see below) you can activate G-Tune with an AUX box (switch) while the copter is armed." https://github.com/cleanflight/cleanflig...s/Gtune.md

I just read this so ill i might try again when I can get more props. They dont sell any in the Omaha area.

Actually in the new betaflight they have removed G rune because it doesn't work consistently.. Still best to tune manually

I defaulted all the PIDS to start over. I LOS for a while until my charger broke. If its not one thing its another .. Here is the recording from earlier

can you post your CLI dump? (use "code" in tool bar )

Manual tunning is still (and i think always be) the best ay to go.

its not so hard, just concentrate on one value at a time. use a simple switch and a POT to tune the value to something that you cen see and feel is flyable. dont even worry on the number its at, just how the quad is reacting and how you feel it flying.

It takes time and practice. I used to spend pkenty of hours trying to tune my stuff, now i can do it in 2-3 batteries (15 miuntes)

Check these links out, they might help (some are not specific to cleanflight):

There you go, its nerve racking at first, and nothing much makes sense until you get and recognize what each value does.

I can see your D value is quite high, to begin manual tuning you should bring down all values concerning I and D, that way P can do its job and you can see how the copter is reacting.

Bring your I for Pitch and Roll down to 20, set D down to 5. P can stay at 4.
For yaw, bring down the I a bit, maybe to 35. I have found that tunning yaw once in flight with the goggles on is much easier. As long as you copter is not drifting in yaw, leave it be for now.

Try that out, let us know.

Thank you so much !! Ill try it out once i get a new charger.. I Just bought it and got everything set up and it broke ..

Try this:

set looptime = 1000
set rc_smoothing = ON
set dterm_cut_hz =  40
set p_pitch = 45
set i_pitch = 45
set d_pitch = 20
set p_roll = 36
set i_roll = 35
set d_roll = 16
set p_yaw = 90
set i_yaw = 55
set d_yaw = 4

---

you should feel the difference right away... but PID might still need tuning, you can upload another BB log with your PID values if you need a hand with that

Enjoy!

I loaded up your recommendations and finally got everything going
I made a video with the logs embedded and also included the files HERE
Im having to correct the yaw with some left stick. It also feels like it doesn't auto correct and i have to level it out alot. any suggestions?

Also here are some more flights from today.. the wind pick up on some of these flights but it was manageable.
