I have just gone through this process and I can not express how perfect the quad feels to fly, it's incredible. Thank you so much for taking the time to put together this guide.
This is a fantastic tuning video for 4.4. This is incredibly easy to follow and I'm grateful that you've provided all of this information to all of us. Thank you!
Chris I have to say It has taken me over a week to follow all of this. However I now have the perfect step response tuned quad thank you for this info.
Ever since your 4.3 guide my quads are behaving absolutely amazingly. I see you also incorporated a lot of the tips from Brian White for this 4.4 version. It's really helpful to get basically the a single strategy merged from you two... and a simple step-by-step guide. This saves an incredible amount of time and confusion and makes tuning a standard part of the build process. Love it!
I have learned so much from you and Mark since I started really diving into tuning and your method is consistent and extremely accurate. I love that you added the detail of Dynamic Idle which many people don't utilize. You covered it all in one 30 min video while providing clear explanations of why you take the steps you do. Brilliant, Chris.
Still like your tuning guides a lot! Much better than these theoretical tuts from Mark and Chris. You are a real pilot that makes the difference. These 2 guys are not flying that much...
Great video as always! A tip using the OSD menu: simply move the left stick left to move back in the menu. Much faster and easier than scrolling to the back option!
I finally fully understand, and am fully effective at Black Box tuning. PID Tool Box was really the icing on the cake, and you couldn't have given a better tutorial on how to use those tools. Brilliant work Chris, thank you very much!
Thanks a lot for chris, it's super useful for me. One thing I found more useful in the P:D balance section 20:58 was using a binary search type approach. First do 3 runs at 0.3, 1.0, and 2.0 Then look at the logs and see if 1.0 is under or over damped. Assuming 2.0 is under damped and 0.3 is under damped then whichever side 1.0 is on, lets you eliminate anything above of below it. For me, 0.3 was massively over damped, 1.0 was somewhat over damped and 2.0 was massively under damped. Because of that you know anything less than 1 will also be under damped, and you don't have to test anything below that. From there you try 1.5 and see how that performs. For me 1.5 was actually about perfect, but for others it could be over or under damped and then you just repeat the process until you can get a really nice tune in what I'd guess to be about 4-6 flights. This would be a bit more of a scientific route to it too instead of just picking some numbers at random.
This is my first time tuning my quads.. Chris says in the video that your D slider should be 2.5 times your pi slider. If my PI slider is 1.6 do I have to times it by 2.5?? At 1.6 PI and 1.0 D slider it looks almost identical to Chris’s final tune. I’ve watched all 4 of his tuning videos and Joshua Broadwell but I just feel like I’m doing something wrong. Any insight, pleassseeeee
Holy crap, dude. I'm following this video with an ultra clean built AOS 3.5 and I keep turning these filters down and seeing nothing. This build is running an F745 too so it doesn't even matter at this point, its just insane to see gyro logs this clean. Amazing work, as always, and thank you so much for everything you've contributed to this hobby
Great vid Chris! Nice step by step. Very similar to the PTB approach. BF 4.4 is really something! One small correction 6:37, FF is currently still active in Angle mode in BF4.4. Not sure what the intention is for future versions, but FF definitely should be turned off (angle or acro) if using the PTB step response tool.
Where would we be without pidtoolbox and the basement tuning method? Great seeing all these videos showcasing your software and how it makes it so much easier to understand tuning.
Thanks for the awesome video Chris. My 2.3" quad flies better than ever now, and despite ending up on higher D-Terms than I'd have ever tried previously, my motors are still cold and pidtoolbox shows everything is tracking great. 👍
You recommend turning off Gyro Low Pass 1 and 2 when setting up. and other settings in the filters. After tuning , do I need to return everything back or not ?
You mentioned using the throttle pump log to optimize filters but didn’t actually do that in the video. You just visualized the log and then used the values from your chart. Did I miss something?
Bogwon, the master of all things relevant! You are my new favorite inspiration in flight. I have been flying the AOS frame for about a year now. It have improved my confidence and skills to a level I have only dreamed about. Now that I'm flying "like" my influencer on UA-cam. Because of your knowledge and passion, we all benefit from it. That is a type of master Bogwon. I thank you, I believe we all feel this way.
Hi Chris! On your previous tuning video you advise to set pidsum_limit = 1000. Is it always applicable or we should keep betaflight default value on 4.4? Thanks in advance.
I think the advise is still the same. He didn't mention tuning filters for gyro itself, for example BMI270 This video is quite short comparing to Betaflight 4.3
Thank you very much for this nice and compact guide. I really liked that you have chosen the small 2 inch for the demonstration because I totally agree with your reasons for that.
I tried this technique of tuning with BF 4.3 for my custom geprc Smart35 frame with 20x20 F722 40A mamba stack (MPU6000) analog vtx and 1404 3750 motors on 4s. I failed miserably. After wrecking my mind and sleepless night I finally gave up and thankfully found your 3.5 inch AOS preset. Applied it and tweaked the D term and I term a step up and perfectly matched my quad. I’m so happy to be able to fly it so well now. Thanks a lot.
Thanks Chris, got through it all now. What was particularly useful was being able to tune my micro inside in angle mode, with only feedforward being tuned in Acro mode outside. Great video, and many thanks.
I tested this method and was easily able to get great results on all my quads within a matter of minutes. Great tip about changing the settings in the osd. Thank you sir.
Thank you Chris, I appreciate the hard work you put in to this and the videoing. I don't think people think enough about the work that entails. I subed, and liked. I have just built a 5" freestyle quad and tried UAV's preset tune. It almost ran away. Went back to betaflight stock 5" preset, and I have a lot of oscillation after a roll. Time to figure it out.
Chris, Hi! I see that code you have written for Angle Mode has been incorporated into BF 4.5 and includes FeedForward. Does this mean that the above tuning method using Angle mode is not valid for BF 4.5? BTW thank you for bringing the Art of Science to this sport!!🙏
Hi Chris, just looked up the specs of the 1002-motor the Sub250 Nanofly20 quad uses and it states that it has a 9N12P configuration instead of the more "standard" 12N14P configuration that the larger motors have. Not sure if this really matters for the tuning process when enabling "Bidirectional DShot" and leaving the motor poles at the Betaflight standard 14 poles as seen in a short video blip instead of 12. Would be interested what potential issues you could see if any. And on a sidenote: I love your scientific method of procedure "consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.". I hope that someday this will make it into some form of Betaflight Auto-Tune capability for the general public. 🙏
You'll want to change the motor poles to 12 on that 1002 motor if you are enabling bidirectional dshot. The correct magnet count is required in order for the correct RPM to be determined. If the magnet count is wrong then the RPM will not be calculated correctly and the RPM filter won't work to the best of it's ability, which may in turn cause hot motors.
Hay chris when using pidtoolbox do i need to change anything in the blackbox recording in betaflight or just leave it at 2 and gyro_scaled? Thanks mate
Fantastic game changer video. Gives a reasonable intuitive understanding of tune parameters, along with specific recommended solutions. Thank you Chris.
Brilliant Video! ;-) Really helped me to understand Betaflight tuning and blackbox functions better and the result is much better handling drones. Thanks a lot!
The crazy thing to me is how you could *feel* where it was going to end up on the graph on my 3.5" I just built. I'm going to try it on my toothpicks that don't have blackbox logging on them. Thank you for this!
I'm finally to the point where I am capable enough to need this guide. Great video. I'm curious about applying the betaflight presets for the radio link. Is that a necessary step for something that is already built and flying, that we just wish to tighten up a bit?
This is so helpful and really appreciate to have you in the FPV community Chris ! I literally copied your whole PID tuning to my BETAFPV 75 pro HD, Rotor Riot Vision 40 and it all works brilliantly and I just need to do minor adjustments to them. May I know if you have flew the BETAFPV Pavo 20 with DjI O3 and if you have the PID tuning to share with me to try out ? 🙏🏼 very much appreciated!
This is a good guide - but you should credit Brian White most of this guide other then the filters section and the dynamic idle is based off methodologies Brian developed and tools he created, there is not any acknowledgment of that which is a shame. With regards to some things in the guide you didn't touch on Iterm Relax which is critical for a lot of drones also I term at 1.0 will cause massive overshoot on any drone over 8 inch - it needs to be decreased as the drone size increases! FF is dependant on I term not just D! FF is not disabled by angle mode that is incorrect
Thank you! But why you don’t show us the process at 22:47 or even little earlier. How to compare all these slider multiplier changes in one diagram? I don’t know how to compare all my logs together to see it like that 😢
thanks man, I dont know why byt your videos seem to make more sense than Mark Spats to me. One day I may actually be able to tune because of you. Setting up Black box explorer and pid tool box right now.
Hi Chris, love your channel. I have a question, when you open the blackbox program, what parameters do you have in the legend when analysing the throttle pump log. I'm really new to blackbox analysis. Thanks Simon.
Hi Chris! This video looks amazing! I can’t wait to tune my quad and make it fly better but I was wondering were/how did you get all the curves for PD balance and Master Multiplier and the ones for feed forward! Thanks a lot😉
Thanks for an informative tuning video Chris. But what about older builds that have DShot600 but NOT bi-directional? I have Armattan Badger circa 2018 with individual 30A ESCs. The ESC firmware is BLHeli32 C-H-25 16.7 latest update. BF4.4.3
I love your proscriptive approach to tuning, as well as your videos in general. However, I tend not to put any time into tuning and instead prefer to use the Betaflight defaults, so that I can focus my spare time on flying. My question, Chris, is whether I would notice a significant difference if I started tuning my quads again?
Many thanks Chris, I did not find a preset for a T100 class 3S quad and will now try to use this instruction as a guideline. If only there were a preset for AFHDS FlySky.
When you do Step Response analysis, Feedforward and Dmax should not be enabled (about PD, Master and I-Term optimization). Otherwise, this can make troubles into results and you could have issues to interprete results.
Great video. I recently got into the Mob6 with 30K kv motors on 1210 biblade props. Using a value of 30 on dynamic idle seems to work best for me. Any higher and my inverted hang time indoors isn't that great. It also doesn't fall out of the sky at 30. Curious to know if dynamic idle should take power to weight ratio into mind rather than just prop diameter? Or just keep going lower until the motors don't spin smoothly at 0 throttle?
Hi Chris, great sharing for PID tune, I follow your step, and set I-Gain to zero and tune P&I Gain. however, when start from 0.4, arm and yaw drift right quite fast. all I need to do it turn the I-Gain back to 1. yaw drift gone and able to arm and take off. why set I-gain to zero and tune like you not work for me?
Hi Chris. Thanks for the video. I'm a bit confused. We looked at the noise graph, but what are we using it for? Right after, you show recommended setting for the filters, but don't ever show how this relates to that graph or how the graph helps us determine out ideal setting.
Wouldn't it be possible to use the function that the new 3D printers have called "input shaping" to analyze the resonances of the motors even on drones?
Hey there, at 4:29 you downloaded a preset for ExpressLRS250Hz, what do I need to do if I am using a DJI FPV REMOTE 2 and not using ExpressLRS signal ? Do I need to download something else or skip this step ?
Hi Chris, thanks for the tuning tips! In the dynamic idle tuning section, i noticed you are aiming a minimum tip speed of 45mph, is there a reason why you increased it from the 30mph you recommended in the specific dynamic idle tuning video? Greetings
Loved this Chris, just retired from 40 years in control and instrumentation so reminded me a lot of my Uni days. However, my quad wont fly with bidirectional dshot switched on. Is there a way around that?
I once spent time in adjustments tab. Used two 3 pos switches and was able to move PIDs up and down while flying. Was fun. Did not know what I was doing though.
double check your frame and arm screws first! was trying to troubleshoot some occilations yesterday and turned out my arm screws had come loose on all 4 arms
First time commenter but long time watcher. Love the vid and couldn’t have come at a better time! Just built my first 2s hd whoop and I’m having serious issues tuning it. The pid loop for roll seems to be normal but im getting some serious oscillations on pitch. I’d love your opinion on what causes there too be more oscillations on what usually seems to be pitch. When flying the whoop I get constant jitters in the camera even when just hovering. Build as far as I can tell is solid. Thanks in advance for any advice
Hello! I am stucked in STEP 1: FILTERS... I have downloaded the Betaflight Blackbox Explorer but I can´t really see all the options that appears on the right side of the screen. Do I need to setup that manually or is there any preset I can download so I can see excatly the same plots as you do? Also, when setting up the Dterm cut off frequencies.. What exactly should I look up in the graphs in order to dial the filter in? Thanks in advance
Hi Chris... I am trying to learn before buying an FPV. This seems a little advanced. Where I can start learning about beta flight? Because I don't even know what is bi directional shoot 😅 Thank you!

Push left stick to the right and hold briefly to quickly get to the save/exit menu. You don’t need to use back repeatedly.
Good to know, thanks!
Or just Left stick to the Left to go back.
I find using LUA script (Betaflight setup) on the radio easier. No goggles needed.
Chris I have to say It has taken me over a week to follow all of this. However I now have the perfect step response tuned quad thank you for this info.

Absolutely great analogy on the Car Suspension.
Hi Chris,
just looked up the specs of the 1002-motor the Sub250 Nanofly20 quad uses and it states that it has a 9N12P configuration instead of the more "standard" 12N14P configuration that the larger motors have. Not sure if this really matters for the tuning process when enabling "Bidirectional DShot" and leaving the motor poles at the Betaflight standard 14 poles as seen in a short video blip instead of 12. Would be interested what potential issues you could see if any. And on a sidenote: I love your scientific method of procedure "consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.". I hope that someday this will make it into some form of Betaflight Auto-Tune capability for the general public. 🙏
You'll want to change the motor poles to 12 on that 1002 motor if you are enabling bidirectional dshot. The correct magnet count is required in order for the correct RPM to be determined. If the magnet count is wrong then the RPM will not be calculated correctly and the RPM filter won't work to the best of it's ability, which may in turn cause hot motors.
Thank you Chris!!!! Yes, can you please make more tiny whoop 65mm 75mm content.. and also 7" tuning content?? Thank you!!!!!!!!!!!!
Hay chris when using pidtoolbox do i need to change anything in the blackbox recording in betaflight or just leave it at 2 and gyro_scaled? Thanks mate

At 3:33 when you turned on the rpm filter, you left the motor poles at 14. S/b 12 on that quad.
Hi Chris, is it no longer necessary to use the CLI commands to open up the full power of the PID loop like you did with previous tuning videos?
I'm finally to the point where I am capable enough to need this guide. Great video. I'm curious about applying the betaflight presets for the radio link. Is that a necessary step for something that is already built and flying, that we just wish to tighten up a bit?

If your best P&I log is set to 1, how do you set D at 2.5x? I guess I missed something!
Best video about perfect pid tune, ty!
Hi Chris! Amazing video as always! Can you say, which parameter I need to adjust if the wind shakes my 3 inch toothpick too much?
Master multiplier as high as possible. This will make it react faster to the wind. Higher I gains might also work
This is a good guide - but you should credit Brian White most of this guide other then the filters section and the dynamic idle is based off methodologies Brian developed and tools he created, there is not any acknowledgment of that which is a shame.

Hi Chris, love your channel. I have a question, when you open the blackbox program, what parameters do you have in the legend when analysing the throttle pump log. I'm really new to blackbox analysis. Thanks Simon.
Excellent info as always. Thank you
Amazing video the only improvement would've been demo flights of the pre and post tune but excellent information please make more thank you
Hi Chris nice videos! What if my older quad is still flying around with multishot, should i replace my esc's? For a better tune?
Great as everytime. Thank you!
@20:30 How do you create the "Step Response Function" graphs?
More "how To" detail need for those of who have never seen BF BB Explorer before
thanks for the masterclass boss!
Nice demo. But I wonder how you could set full throttle inside the home without hitting the ceiling 😅
Hi Chris! This video looks amazing! I can’t wait to tune my quad and make it fly better but I was wondering were/how did you get all the curves for PD balance and Master Multiplier and the ones for feed forward!
Thanks a lot😉
I mean in wich software
Ho it’s in the description
Thanks for an informative tuning video Chris.
But what about older builds that have DShot600 but NOT bi-directional?

My question, Chris, is whether I would notice a significant difference if I started tuning my quads again?
Hello Chris! One question.
For the PD balance, it is the same to move the damping slider (D gain) or to move the Tracking slider(PI Gain)?
Thank You!
@ChrisRosser why do you recommend the biquad, when BF docs suggest avoiding it and using pt3/4 instead?
Many thanks Chris, I did not find a preset for a T100 class 3S quad and will now try to use this instruction as a guideline. If only there were a preset for AFHDS FlySky.
When you do Step Response analysis, Feedforward and Dmax should not be enabled (about PD, Master and I-Term optimization). Otherwise, this can make troubles into results and you could have issues to interprete results.
yea i wondered why he doesnt drop dmax to 0..
Great video. I recently got into the Mob6 with 30K kv motors on 1210 biblade props. Using a value of 30 on dynamic idle seems to work best for me.

Curious to know if dynamic idle should take power to weight ratio into mind rather than just prop diameter? Or just keep going lower until the motors don't spin smoothly at 0 throttle?
This video is insanely good! thank you!
Hi Chris, great sharing for PID tune, I follow your step, and set I-Gain to zero and tune P&I Gain.
however, when start from 0.4, arm and yaw drift right quite fast. all I need to do it turn the I-Gain back to 1.
yaw drift gone and able to arm and take off.
why set I-gain to zero and tune like you not work for me?
Hi Chris. Thanks for the video. I'm a bit confused. We looked at the noise graph, but what are we using it for? Right after, you show recommended setting for the filters, but don't ever show how this relates to that graph or how the graph helps us determine out ideal setting.
Wouldn't it be possible to use the function that the new 3D printers have called "input shaping" to analyze the resonances of the motors even on drones?
Hey there, at 4:29 you downloaded a preset for ExpressLRS250Hz, what do I need to do if I am using a DJI FPV REMOTE 2 and not using ExpressLRS signal ? Do I need to download something else or skip this step ?
Hi Chris, thanks for the tuning tips! In the dynamic idle tuning section, i noticed you are aiming a minimum tip speed of 45mph, is there a reason why you increased it from the 30mph you recommended in the specific dynamic idle tuning video? Greetings
Loved this Chris, just retired from 40 years in control and instrumentation so reminded me a lot of my Uni days.
However, my quad wont fly with bidirectional dshot switched on. Is there a way around that?
from 4 videos on bf tuning (2 hours ) to 20 mins, top content
I once spent time in adjustments tab. Used two 3 pos switches and was able to move PIDs up and down while flying. Was fun. Did not know what I was doing though.
another great video from a great engineer! good job Chris, I really appreciate!
Hi Chris , i want to ask about " Feedforward - Transitions " what is transition does on the quad ?
Watching this video third time, every time I advance how longer I can watch it before I fall asleep 😂 it seems like I need couple more attempts 😅
if you press right with the right stick in osd you go strait to save and exit/reboot (for making new logs)
double check your frame and arm screws first! was trying to troubleshoot some occilations yesterday and turned out my arm screws had come loose on all 4 arms
First time commenter but long time watcher. Love the vid and couldn’t have come at a better time! Just built my first 2s hd whoop and I’m having serious issues tuning it. The pid loop for roll seems to be normal but im getting some serious oscillations on pitch. I’d love your opinion on what causes there too be more oscillations on what usually seems to be pitch. When flying the whoop I get constant jitters in the camera even when just hovering. Build as far as I can tell is solid. Thanks in advance for any advice
Hello! I am stucked in STEP 1: FILTERS... I have downloaded the Betaflight Blackbox Explorer but I can´t really see all the options that appears on the right side of the screen. Do I need to setup that manually or is there any preset I can download so I can see excatly the same plots as you do? Also, when setting up the Dterm cut off frequencies.. What exactly should I look up in the graphs in order to dial the filter in? Thanks in advance
Hi Chris... I am trying to learn before buying an FPV. This seems a little advanced. Where I can start learning about beta flight? Because I don't even know what is bi directional shoot 😅
Thank you!
Could you do a tutorial on using neural networks in predicting the optimal PID values?
Instant thumbs up 👍
