I'm still struggling with vibration and I can't work out what is just noise and what's bad tune. I've gotten my quad somewhere close with trial and error watching video after video! Could someone give me a little hint or tip to clean it up. Am I close? Are my deductions below right? Am I on the right track or am I making huge errors?

From this, I decided Roll and Pitch P's needed to go up a bit, ds a tiny bit to follow.
I decided I on all axes should stay the same.
Yaw P I keep turning down, but I've just seen one video which says that vibration like that on the yaw axis is normal and unavoidable.... so I might have to rethink my methods for yaw.

I also know I shouldn't have flown over the car park... especially as I'm PID tuning a new flight controller after a full rewire with batteries I'm borderline replacing... a risk I won't take again.

YEP...it was so much easier to tune a quad back in the analog days...the quad would give every sign you needed to tune it...but now days, RF and betaflight takes ALOT of that away with filters, fight modes, etc.....this would be the main thing i would look for when i am tuning....

motors hot after tuning Ds, might mean Ps are too high...
tune till you dont see any more change in P..or vibrations get worse...then back that setting off by like 10 or 15%, tune Ds to match...
or tune till you like the "feel" and tune Ds to match..

sounds like you havent tuned many quads, so youll have to play around..set a PID controller to a tune so you can fly the thing, then when you think you want to try another tune, tune it on another pid contoller that way youll still have your old PID tune so at least you can flip a switch and rip..

for the most part, us regular people are not going to tell if P are off by 2-6 points...youll learn to rip the shit out of it either way...look at it this way, if two indy cars are built EXACTLY alike, they still will never drive the same but the driver makes up for difference,.....i know you watched ALOT of vids, so did I, i still do, what i had to get away from was seeing youtube quads, and wanting mine to fly like "that"...heres the kicker, 50-75% of the "youtube tuning" is the pilot flying the quad. the pilot is really the one responsible for smooth flips and rolls, or a nice rippy U-turn.. i have noticed over the years the more i fly the more i notice things, now I realize I was tuning without even knowing how to fly or what to expect or what i was looking for..Its shitty, i know..but it may take 4-5 quads till you start really seeing the difference in tunes..Im on my 7th and about to build #8..

bottom line is, tuneing is the feel of the beholder, it is what ever feels right to you.....remember, dont forget to fly..

by the time you learn betaflight will have a SELF TUNE mode...lol

Welcome to the forum!

The black box log says that you're running on a 4KHz gyro sample rate. Any reason why you're not running 8KHz? Are your ESCs really only capable of OneShot125?

What is the quad built around? I can see from the black box log that the flight controller is an Omnibus F4. What frame, motors, ESCs and props are you using? Some photos of the quad would be good to see how you have put everything together. A 'diff' from the CLI would also be helpful.

Your PID D term traces are horribly noisy and I can see lots of jello in your video which tends to suggest that your quad is vibrating quite significantly.

Set the gyro sample rate to 8KHz and the loop time to 2KHz. Reset filters and PIDs to the defaults. Go to the CLI and 'set debug_mode=notch', save and record a short log. This will let you see the raw gyro values and see how much vibration there really is.

Most quads fly perfectly adequately on the default settings with the latest releases of Betaflight.

Thanks Nitro, this is my first quad, and I'm deeply obsessed with every element of it!!! I've seen autotune on Betaflight, although didn't get much from it, they since wrote it out anyway. There is another firmware with one which is apparently very good (I forget the name) but the limited compatibility doesn't qualify for me unfortunately.

Unseen, thank you, you've accidentally taught me a new lesson. I was considering noise from the craft itself, but it wasn't until you pointed it out, I discovered the two older motors have a slight bit of up/down play in the shaft. I've looked carefully and the bearings don't seem to be moving with them, it seems I need to loosen a screw in the bell to let me tighten it, maybe that will cut the rubbish out. I didn't think much of it, but I replaced two back motors after I fried one playing with blheli (yep another lesson learned about smoke stoppers and why more volume =/= more good...) Those have no play whatsoever... My precision driver set doesn't go that small so I'm picking up a new one tomorrow, give the shafts a tighten and see what a difference that makes.

Oneshot yes sadly, it's a frankenbuild and the front two escs are from the original wreck. They can handle what I need, I'm too new to the hobby and will probably kill this one completely by the time I can tell the difference between dshot oneshot125 etc. The first incarnation of this quad was pwm! But the way I wired it looked cool!

I turned the frequencies down recently after a bizarre loss of control. Blackbox showed full controls were being received, but the pid controls were happy keeping the current attitude and ignoring me, someone suggested overloaded CPU but this looked more like a battery voltage issue so I'll also turn those back up.
