Almost a year later, I keep coming back to this one. This video was a turning point for me - I "slider tune" every quad I care about now, coming back here time and again to get the steps right. Thanks for this!

Loolllll.same....

The simplicity of this tuning process is brilliant. Finally a tuning process that will get me most of the way there without being over complicated and drawn out!

Thanks Mark. I was able to follow everything you said in this video without re watching it 6 more times! Your tutelage is paying off :)

[@scottdickinson4528]

Seriously thank you so much. This made tuning my rough flying cinewhoop soooooo much smoother and got it dialed in for my needs. Huge thanks!

I really appreciate this video as it's a bit less in depth than some (where I get lost!), yet includes enough valuable info with some basic black box reading. By taking a laptop to the flying field, I believe even I can follow this strategy!

There's a guy at work that we ask for guidance. We call it, "drinking from the firehose". Watching your videos is a lot like listening to him. Someone who sees the big picture and not just "it has always worked for me". Really good stuff. This is one I will probably pull up out of my history and watch a few times more.

[@CgitEinsteins]

Thank for video, i will try and see the difference on my quad.

This has got to be the best 4.x tuning video I've seen to date. Much appreciated! (I was able to pick up a lot of understanding of how the parts work by the way you approached it.) Well done! And same as KababFPV (hehheh) I couldn't wait to comment until the end. :)

Very interesting and informative video. You made it easy to follow along . I couldn't see the bounce back during the flight. The black box helped. Really awesome hearing the trilling props and seeing that in the logs. Thanks for sharing. 👍🤓

[@TheMachadomachado]

Wow... I did some kwads in the past using your tips, but this must be the single most easy to tune guide available in the world!! I just did two tunes for the same craft, 2 packs for 6s and 2x 4s... Final result is amazing. By the way the tip for the pwm frequency was crucial, I was using 48khz in jesc and flying in 4s was giving huge oscillations that previous tunes were not taking out easily.

[@mike216ism]

Your the best Mark! I've come a long way because of you. Now I'm a black box logging pilot. Could have never done it without you. Much appreciated. I hope you and your family stay healthy and safe

[@SteveCEvans]

Having spent a long time manually tuning both a 3" (DalRC DJI F5) and 5" (Armattan Marmotte), both with DJI and running 6S, without using the sliders, your video prompted me to go back and see what slider settings would get me closest to that tune. I'd tuned P, then D, then enabled Dmin and retuned D, and then FF and I for each axis. On the 3" I found that just PD gain just needed tweaking to 1.1 and I ended up with pretty much exactly the numbers I'd found the hard way (except for FF which needed to be 150/175 on R/P). On the 5", tuned the same way I found that PD balance of 0.8, PD gain of 1.3 and Stick Response of 1.9 (except for yaw which tracked perfectly with FF corresponding to Stick Response of 1.0) again matched those values resulting from lengthy tuning. In both cases the ratio of Roll/Pitch gains seemed spot on. The only thing here which seemed to be consistently out was FF. Again this video shows that black box is priceless. One thought here though... I find that I can raise P a long way if D is relatively low, but then the quad becomes very sensitive to bursts of P oscillation during prop wash. Raising P until you get trilling with the PD balance at about 1, and then backing off by the equivalent of 0.1 to 0.2 on the PD gain slider, and then adjusting the balance to get the damping right (no under/overshoot) works better in my experience. Done in this order, PD gain before PD balance, the fact that PD balance adjusts D, not P, works in your favour.

[@findler]

Hey, i am also running a marmotte with DJI on 6s. would you mind sharing your bf settings with me? I think my quad moves decent but there is room to improve. Which motors are you running and how much does your quad weight? I fly with a Session 5, recently cutting weight, think I will be around ~720g as soon as I replaced my stack and motors.

[@SteveCEvans]

[@CarbonGlassMan]

I'm going to have to try this after work today. For the first time, after 7 builds I have a quad that starts out with horrible bounce back and bad prop wash. Usually the stock settings are pretty good. This 5 inch is almost unflyable

[@SteveCEvans]

It's father's day... surely you're allowed more than just the two packs!

[@uavtech]

Yeah, maybe 3? ;-P

[@ronboFPV]

Thanks!

[@seagullhunterfpv]

Really good straight forward Tuning video. I've been flying since BF2.x and theses sliders make things so much easier to tune. I know a lot of people who've not long got into the hobby and they don't realise how easy everything is now compared to earlier versions. I currently have 56khz RPM Filters enabled on my quads and one of which I've never flown before hand so I don't really know if I'm missing anything, but on a 5inch I've had for over 3 years I feel like it's really underpowered now compared. I noticed you used 28Khz instead so would you recommend that over 56khz for most or all Quads? Also at 56khz I'm running 4k PID and DShot300. Would you recommend the same on 28Khz ESC's?

[@icebreakerz46]

Thanks for this helpful Tutorial.....still waiting for these awesome Fortnite-Videos :D

[@uavtech]

No billion likes yet, so he is stuck. :-P

[@jordannovek2911]

Great video very useful,Thanks. When adjusting filters is it ok to let the motors get just slightly warm so I can get better propwash handling ? Thx ,peace

[@uavtech]

Yup, warm is ok.

[@beechFPV]

I’ll be following this video to tune my quad. Could you do. A cinematic tune please

[@Dad_K]

Top tier video as always. However, why would you not set a dynamic idle value? Is this not needed to prevent desync when using bidirectional dshot/RPM Filtering?

[@strawhatsam]

17:00 going on a tangent, I love it!

[@splif7773]

Great video very useful info, do you have any suggestions for a 5 inch 6s 2208.5 2222kv, do I need pids reduced by 1/3 since motor output is set to 82%, and for BLH32 should I use high demag, 48khz, 24khz and have you ever tried 36khz khz?

[@uavtech]

Don't do general things like that. Just tune it.

[@richardjustice6220]

Very helpful and makes sense, thank you You turn Dmin off at the start “as it’s a tuning flight”, should it be turned back on once tuned? Thanks again You should get in touch with Volvo, the lane assist PID tune is terrible on mine

[@uavtech]

Up to you. Just make sure to remember you D_min gains should matched your tuned gains. D_max is only seen on sharp stick moves.

"move those P/D gaine UP" vidéo montage is insane! XD idk how i saw it...

Great video! what filter settings would you recommend as a base line for 7 inch?

[@uavtech]

Same except sliders at 1.0

[@fcass]

I need to go through more of (all of) your videos to really learn to tune. I have one 5" quad that does the 'trilling oscillation' when I strap a 120c pack on it and hit high throttle marks. I could probably make it go away applying a little of what I learned here, but honestly I don't really understand what TPA breakpoint does (I'm guessing it reduces your pids when you reach a certain point) and I want to tune them right all around. Could you point me to your most complete and easy to understand pid tuning video? Or do I just need to watch them all hehheh. Thanks so much. You're a treasure to this hobby.

For the rpm filtering you set PID loop frequency to 4khz and use dshot300. Do you recommend the same settings on f7 boards, or should we then use 8khz and dshot 600? Thanks for all your help, my quads fly great thanks to you 👌

Yup

[@scottdickinson4528]

@@uavtech Does this work for BLHeli_S also? Ive done the jazzmavrik firmwire updates for bidirectional d-shot, but I've never played with any of the ESC settings in that config tool like you did. Is it still possible to get a decent tune without this step?

[@AlenHR]

dude, whatever you do, your quad flies much better than mine, hahaha i changed motors on mine and now it flies much smoother in slow flight but propwash is so harsh i almost loose control on occasions. gonna tinker with it until i figure something out.

[@lordango]

Great video! I just did my first tuning using your steps. I cannot however hear the trilling oscillation so as soon i felt the motors getting warm, i backed down two notches. One question I have is, do we leave "D Min" toggled off? By the way, I have a tiny whoop (tinyhawk 2) no Black Box recorder.

[@uavtech]

I typically do, or turn on if i want some more overshoot control. In that case, user sliders to make D_min values the same relative gain numbers you found in the tuning process. Then during sharp moves or wash, gain D-gain boosts up toward max values.

[@burdenfpv8628]

Hi Mark, really love your videos, great work! Was just wondering, do all of the initial CLI commands you suggest entering in betaflight 4.0.3, at the initial stages of your PID tuning principles playlist, still apply when tuning in 4.2? Cheers.

[@uavtech]

Yes, but the FF = 0 diables the sliders, so this trick with FF slider and FF Transition helps to keep them active.

[@burdenfpv8628]

@@uavtech ok great, thanks. I'll use that then and leave the FF changes out of the CLI commands. Cheers.

[@bisarowood]

I do appreciate your knowledge , seems like what we need is an auto tune feature ! fly a couple packs and the quad will tune it self to your style ...? possible ? I know the Vbar has a feature like that for RC heli

[@brandonwoodford579]

Hey Mark, got a quick question. I have been working on my pids, I have gotten to a point where i am getting trilling durning 0 throttle maneuvers. Like a roll or a flip, during the flip it sounds like a dump trucks breaks, or horn. Its only during flips or rolls. The noise is all comming from pitch dterm. Pd balance is on pitch and roll is 1.1. 55roll p, 50roll d, 60pitch p, 55pitch d. It looks like a trilling ossilations on pitch dterm on the log, but doesnt sound the same because it only does it at 0 throttle.. To much D I think, and to high of FF. 1.5 on slider (148ish) thanks

[@IroncladTutorials]

5:45 was trippyyyy

[@vanair]

Hi Mark, thank you for the very helpful tuning guide!!! Can you tell me, why you only look at the Roll-Axis during the Tuning? So far i have only looked at the Pitch-Axis (and go crazy with Overshoots and Bouncebacks in Flips already at BF Stock Values). Should I always only look at the Roll-Axis?

[@uavtech]

You can look at either.

[@dhardjono]

nice i will try . just got my dji goggles i wish i got it with remote.

[@TheAwesomefunny]

I tried this method on my first custom 3inch build. It flies significantly better and the tutorial was easy and straight forward to follow. I flashed the ESCs with the 48khz firmware, do you recommend moving back to 24khz for a 3 in just under 250 grams Thanks! It earned my subscription!

[@uavtech]

for a 3", i reckon 48khz gives you the longest battery life.

[@PIDtoolbox]

I like your approach of minimizing the degrees of freedom early in the tune. Temporarily killing FF makes a lot of sense to me. I think a lot of folks don’t get P gains right because of the confound with FF. wrt the 3rd RPM harmonic, it should have virtually no latency cost right? Why not just leave it on? I also think most could run Q1000 there.

[@uavtech]

Agreed Idk, minimal latency, but minimal use too (3rd harmonic).

[@DelixFPV]

Great video! BTW if you put the FF to 0 on RPY the sliders will not go away as before, not sure if is now a bug, I like to think is a feature!

[@KLNYC]

Good one! I follow JB method.. So far so good. Does this applied same at 4S or only in 6s like you flying now. Thanks

[@uavtech]

All S and all quad classes. It is just how you tune a pid controller.

[@Jamesn-js1zp]

Thank you, that's a great approach. Is it possible you're able to do similar for something like a 3" set up?

[@uavtech]

Yep, it is the same process though.

It is hard to put in all forms. Look at the comment right before yours. Also a beginner and it translated just fine. Also try tiny.cc/pidtuning and see if that helps

[@BrainDeadEngineering]

I built a contraption to measure linear thrust from different props types . How can I disable the stabilization / gyro in the FC ?

So great! Just what I'm looking for. Why didn't you boost the PID sums to 1.000 before the tuning?

It was already done. Missed instructing that. It is less frequent it is a constrains than more. So for general, ok to keep out to keep simple.

[@mr.m.4887]

[@BrandonBeans]

I like your method. What's the other method of using the sliders (the method that required changing how the pd balance works)?

It use to old D and move up P as you moved PD Balance higher. Now it holds P. :-(

What in case you get evident bounce back when you close the throttle at the top of a loop and point down?

[@uavtech]

Need a good PD Balance tune and crank the PD Gain up.

[@splif7773]

So in your experience for a 6 inch 6s quad should be around 1.7 for pd balance and gain?

[@jeffjorczak]

Did you leave the filter sliders at 1.5 indefinitely, or did you come back and tweak them afterward?

[@justinflipflops]

I'm late to the party, but a bug / useful feature of 4.2(at least with my RADIX2 BrainFPV builds of betaflight), if you set feedforward to zero, hit save, and refresh. the sliders will re-enable with feed forward / sitck response gain = 0, completely removing it from the mix. :)

[@MEKZfpv]

Maybe a very stupid question but when you do this tuning is it better to have fresh props of is it better to do it with banged up props?? And do you keeo D_min off afterwards or do you put it back on? Yes I am a noob at this (but willing to learn)

[@uavtech]

I use average props. For D_min sometimes i turn it on and sometimes i leave it off. Depends how aggressive I get with FF and the quads other flight characteristics.
