How to Fly to your "PERFECT" Tune.

[@PIDtoolbox]

great tips Mark! Thanks for the video! One thing I'd add is, in order to really see the vibration profile if using spectrograms for example, it's good to do fairly SLOW 0 to 100% throttle sweeps (10sec or so). That way, we have lots of data across the throttle range with no gaps, which is ideal for spectral analyses, and we can more clearly see the full vibration pattern, which is ideal for looking for MTOs and such

[@brianevans4]

Your flips and rolls are so exact and precise and clean it's so satisfying to watch

[@allaboutvisual]

New to your channel, love every single video, well done and I would say you are the king of PID!!!

[@justhackitfpv]

You are an amazing guy only KZbinr who answers everything at This detail Other KZbinr - Crazy Unrelastic things about PID Tuning UAV Tech- Blasting it out I Only go for fc tested by him and drone mesh These two guys are only who know what they are doing.. love from India and be safe

[@Mateyhv1]

Good video and nice summary at the end! Thanks Mark for shearing the knowledge

[@Switch180fpv]

Thank you from the video your quad looks like it tuned perfectly already 🙂

[@uavtech]

Yeah, she is pretty well spot on. Next one will show that tune.

[@Sweethomemovers]

Dope content. Can't wait to see more

[@Burn377]

Thanks mate! I'm still pretty green to tuning so this will give me something to play with on the weekend :)

[@blaqmoses5274]

thank you mark. I've learned something today. i appreciate your effort to teach us how to tune these freakin flying robots .

[@nekoth]

Thank you for a great video. Could you elaborate a bit more on how P-term setting is influencing drone behavior on throttle punches (or link to the video where it is described in more detail)? I have a bit of trouble making drone be stable on sudden throttle punches (nose is dipping or raising from time to time), had a bit of success by increasing antigravity + I a lot, but it doesn't seem to be a proper solution. Just don't get how P is affecting it, as I am not touching any axis, so 'setpoint' should not be changing... so I must be missing some of the key parts here.

[@uavtech]

kzbin.info/www/bejne/iZXEqGiPhduEeNk P-term pushes the gyro stay on Setpoint whether it is moving or not. I-term too, but over long biases. P-term is the shot stuff like a bobble.

[@nekoth]

@@uavtech thank you, looks like I was understanding setpoint a bit wrong - as an 'external control input on axis' and it was confusing me, now it makes sense.

[@sidneyspahr468]

You look so tired at the end when your talking lol. Keep it up man i now at this point have a quad with gyro off and d lowpass at 1.8. And cant get it any better it feels like. That's because of you. Thanks bro

[@davegoddard]

dam man, that tune looks great. any chance we could convince you to post the black box log so we can all see what its supposed to look like?

[@stevo43068]

Nice, I learned something today!

[@RobertLeclercq]

Do a 7" tuning video!! 5" is pretty easy to get beautiful footage out of. I want to see the master tune a 7"+, I know you could do a lot better than I.

[@uavtech]

I don't have a 7" yet. But have helped folks tune them. It is the same process. We just did an 8 blade 7". It was exotic for sure. PIDs nowhere close to defaults.

[@RobertLeclercq]

@@uavtech The PID tuning is the same process, yes. To get that silky smooth, ABSOLUTELY NO BOBBLE, straight line footage, lots of work needs to be done with other features, such as RC smoothing, and various FF features. Caps all over the place, BLheli32 timing and PWM Freq ect... I'd just be interested to see how easy or not it is for you to give us that 7" + butter. I think I may have finally cracked it with 4.2. 3.5.7 produced silky smooth footage at the expense of warmer motors. 4.0 and 4.1 got the temps down but FF introduced 'bobbles', along with loop time instability with RPM filter I'm sure wasn't helping. 4.2 gives me cool motors and after a bunch of tuning ALMOST no bobbles. I am VERY VERY VERY Picky about my smooth footage, 1 slight bobble and its GARBAGE. Long live 4.2

[@brianevans4]

Yeah I'd can attest that 7 inch is very difficult to get a good tune. I am not the best tuning at the best of times, and seven inch is a nightmare. So much wobble in the HD video

[@Max-ie6ke]

@@RobertLeclercq Hi, can you share you settings to have smooth HD footage ? Thanks mate

[@RobertLeclercq]

@@Max-ie6ke github.com/betaflight/betaflight/wiki/4.2-Tuning-Notes I just followed the tuning notes and applied them to my specific use.

[@stevenkelby2169]

Great info, thanks. Keep up the great work 🍻

[@sketchpv3080]

Excellent tutorial. I wish you had elaborated a bit more about ways to correct certain poor flight characteristics, but I’ll be sure to check out your other tuning videos that you mentioned.

[@uavtech]

I will in a later video. I wanted something short in this one.

[@robaxelsson530]

Thank you for all the information.. what camera angle would you suggest when doing this tuning? It appears your rolls are “centered”..

[@uavtech]

Your normal camera angle.

[@criminalfpv]

New knowledge coming in... ✊😋 Simplified thanks man, I have followed your tune, information.. d gains, d advance/gyros.. ect.. I think .. anyway my quad fly's so much better!! And I'm learning all the time! Building a mental picture of quad tuning!! 💡

[@Fleche_FPV]

Regarding the tune of I what is the method, because I do not remember having seen something on it ... Thanks so much for all your lights !

[@uavtech]

It is in the guide: Http://tiny.cc/pidtuning

[@Fleche_FPV]

@@uavtech 😅 sorry !

[@uavtech]

No worries.

[@mikestanton2824]

Mark great tips on PID tuning, but I have one question do you have "air mode" enabled or on a switch?

[@uavtech]

Airmode is always enabled on my 5" quads.

[@gerdanc]

Can you please do some in depth tuning without BB? Your methods are the best I’ve found but many of my quads don’t have BB. Especially toothpick/ micros. I’ve read you google doc and watched the series several times. It’s helped a lot but I’m struggling to balance hot motors and prop wash.

[@uavtech]

I have been thinking of this, but what I struggle with it knowing what is what without blackbox. One issue could be 3 or 4 things, and only Blackbox lets you know which it is.

[@FPVStyle]

Very good I will go to fly and try what you show thank you

[@100100freak]

Hey, I have a problem I can't solve for quite some time now. I have a crystal clear fpv feed until I turn on my radio. Suddenly my osd starts to flicker around and it can get so worse that the picture is nothing but static. My antennas are isolated and and so is my r-xsr and my unify pro 5v. It seems that the radio control link interferes with the video. By moving the antennas of the r-xsr I can sometimes get a good picture by holding it in a position or by taking the r-xsr out of the kwad and hold it above it. But as soon as I put everything back in place the same problem occurs..I'm just desperate at this point because i tried everything I could imagine being the problem

[@uavtech]

I would be guessing. But check your VTX connector is not touching the frame.

[@i.v.2824]

Mark...what's up buddy? Hope you and your family is well during this crazy time. Good to see a video from you buddy. Defaults fly almost perfect on my new build. I'm sure you could make it better than I can but only one issue that I notice. When I punch out and drop throttle to zero I get a bobble...what would most likely cause this? Not enough P on Pitch? or Anti gravity too low?

[@uavtech]

If a fast bobble, it is P too low on Pitch. If a slowish kind of dip, then that is AG.

[@ktmjay9920]

Great video, really appreciate the help 👍

[@hector-fpv]

Hi Mark, thanks for the video. At minute 3:10 you talk about this issue that has been driving a lot of people crazy (Bob Roogi mentioned this a lot in his videos). I have both Betaflight and Kiss quads. Kiss quads do this same thing too, and Kiss does not have antigravity. I almost 95% got rid of this bobble in the Kiss quad by raising P and D in both pitch and roll axis maintaining the same P/D ratio that default pids have. I still have not been able to eliminate it in my Betaflight quads :( Just wanted to point this out, hope you find it interesting!

[@uavtech]

Yup, throbbles just needs a Critically Damped tune on Pitch, and then increase PD Gain to fight it back. All these firmware use the same basic math for the PID controller because it is just so basic. 1+1=2 no matter how you slice it. So just to the same thing.

[@jorgeromero4680]

what's the setup on this quad? also i would like to know how much it weighs. Looks so floaty. Thanks

[@illusionfpv708]

Perfect sequence 💪🏻

[@3acspace]

Do you have any tips on how to tune for 1s toothpicks? Specifically about crazybeef3 fc boards, i couldnt do blackbox logging on those.. been trying to tune it for 3 weeks now still not satisfied with how it flies.. thanks in advance man, appreciate all your hard work in putting out all these tuning videos..

[@uavtech]

Follow the guide and series. tiny.cc/pidtuning

[@jmcinematics]

I got ossolations on 5. Smooth forward flight > What is the advice too smooth this out (7inch)

[@uavtech]

make sure your props are not completely off balance and your arms are extra stiff. then start with stock BF settings.

[@CaptainMavic]

Very helpful, thanks!

[@pietlopsa9164]

Hey, what would recommend for a 5 inch 6s quad in terms of d? Is 45 still adequate to tune the p d ratio? Thank you so much!

[@uavtech]

Depends on the power to weight ratio. For a fat boy, i try to be in 40s. For light racer, 20s or 30s. Honestly you want it as high as you can without negative side effects.

[@pietlopsa9164]

UAV Tech thanks! Im coming in at 620grams with battery and everything, around 40 should be alright i guess

On. Rails. Do you have any experience with R9? I'm only missing the DJI controller at this point an am wondering how it does long range?

[@chrisdorsey7961]

How would you recommend tuning out prop wash on split s drops?

[@uavtech]

See tiny.cc/pidruning You have.to have right, and then turn up PD Gain. Depending on motors and props, you may never get ride of it. Motors hit saturation and can not update rast enough. Of if too much noise, you need too much filtering which causes too much delay.

[@Gho5tface]

For anyone wondering: tiny.cc/pidtuning is the correct link

[@hamadmusabeh]

this is the way

[@hateeternalmaver]

Perfect timing! Thanks for your work and stay safe, Mark.

[@jamiegerrard2129]

Thanks for the video! This hobby is like learning rocket surgery in the Klingon language!

[@uavtech]

Yeah, half the fun! :-) Or maybe not sometimes.

[@Rich2brokeN]

so jitters I get just cruising straight will most likely be p is too low beta and flacox that is the only thing I see in my video like it has chills just cruising

[@smooth_ops2942]

Could also be a D MIN issue... Raise both pitch and roll D MIN by 5 and see if it improves and if it does adjust from there, if it does not try turning D MIN off completely by putting each value to 0 👍🏻. Good Luck

[@uavtech]

Could also be a noise filter problem too. That is the trouble with quads. A single symptom could be a number of things. Logging gives insight on which is the true problem. However, if not windy, I would venture it is P is too high. But again, it could just be a vibration issue that the firmware can't overcome, or filter settings are too high. Like Smooth_Ops said, D_min pushes down D-term, which results in a P/D Balancing being pretty high, which is the same as P-gains just being too high. Personally, I would take a log with Gyro_Scaled recorded, make sure it is not a raw vibration or bad fitler settings problem and if those look good, then move on to looking at PIDs. Conversely, you could turn off D_min OR decrease the PD Balance slider in BF to see if that helps too.

well, "anti gravity" is possibly the worst name for anything ever. In my opinion, it competes with microsoft's ".net" framework for worst name of all time. also, your videos are awesome :)

[@dilbertmcfly5986]

Pfff... blah blah.. stock BF, PID is flyable for most 5inchers. Now try it on a 9"-10". Vibrations, and frame harmonics down below 80Hz in propwash region and prop balance issues.

[@uavtech]

Pffff, yeah yeah. Move down the lowpass filters. It is all customizable. Just tuned a 8 prop 7" with this method. The point of this video is how to fly to stress the pid loop to tune it. The vibration issues associated with big props is legit PITA.
