Now that I have the holes in my ceiling repaired, I'm going to try this process again. This time, outdoors.
😂
😅😅😅😅
You are a true gift to the fpv community. Thank you for all of you work! 🙏
yes
Facts.
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.
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.
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!
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.
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!
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.
Fantastic game changer video. Gives a reasonable intuitive understanding of tune parameters, along with specific recommended solutions. Thank you Chris.
Finally someone explained tuning and filtering where I can almost understand it! Thank you!
Chris, thank you so much. You brought tuning videos to perfection. This the pinnacle of the series
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.
The suspension analogy!! So perfect.
This is not just a video, a lecture actually. Thanks for your high quality effort 😎
Thanks Chris, this is pure gold! Now to watch on repeat & & take notes !
This is an amazing lecture on quad tuning!
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
Thank you Chris, new to FPV, I want to dive deep into tuning and you gave me all the education I need to get started!
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.
Who is Mark? I'd love to learn more about Betaflight
@@olegvlasov2744 youtube.com/@uavtech
@@MurdersFPV thank you
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...
I'm in the process of retuning of my quads right now, including one AOS frame! Thank you for all you have done on this topic! Great content 🙂
YES! If Chris Rosser is going to teach me how to tune it, I better order one before they are out of stock!
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. 👍
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!
Thank you for the video. I have to watch it again because I have visit and I did not heard much of it.
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 CZcams. 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.
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.
Love the college format presentation, very clear. 👍
After your last tuning guides super excited for this
Absolutely great analogy on the Car Suspension.
HUGE TIP... @ 20:05 move left stick right to get to save & exit menu FAST!!!
came here to say the same thing, made my day when I accidentally happened across this shortcut
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!
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.
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.
another great video from a great engineer! good job Chris, I really appreciate!
I never truly understood PD until you explained it as car suspension. Amazing!
great video.. im starting to catch on .thanks for the time you put in to thios hobby,.
love how much you share with the community. great informative content again! do you recommend any particular black box serial port logger?
The car suspension analogy was pretty damn spot on man such a good way to explain it in laymen's terms
The best guide to date!!! Definitely learned a lot today...!!
Excellent info as always. Thank you
Brilliant Video! ;-) Really helped me to understand Betaflight tuning and blackbox functions better and the result is much better handling drones. Thanks a lot!
Best video about perfect pid tune, ty!
Awesome video. You are My Rosetta Stone of PID Tuning
You're awesome. Finally I learned how to tuning any square 🤠
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.
Thanks Chris . This was very helpful mate 💪🏻🤘🏻
Great as everytime. Thank you!
Master class !!! . Awesome video Chris. Thanks.
This video is insanely good! thank you!
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.
thanks for the masterclass boss!
Very good guide, thanks!
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
Thank you very much!!!! Great video
gracias Chris por tu trabajo y aporte saludos..
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 to hear! Thanks for the message and your support.
Amazing video. Thank you so much.
I love your videos... really brings me forward
Great video!
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.
from 4 videos on bf tuning (2 hours ) to 20 mins, top content
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?
Thanks for this... I've been on emuflight for the last few years and just switched back over to betaflight last week as it supports the osd better for walksnail.
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!
you can also use the yaw left to go back on the menu
Thank you for such an informative video. Im doing this outdoor with a little wind. Would the wind affect the result ?
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.
LOVE YOUR WORK BRIAN!!!
@@xxxplode5999 thanks man
Brian is the real hero here! If not for him this video would never exist! Cris should have plugged brian more
@@fr3style I agree!
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.
👏👏👏👏Merci beaucoup pourcette video j'ai appris plein de choses grâce à vous
Thank you so much. 😊👍🤝
Amazing video the only improvement would've been demo flights of the pre and post tune but excellent information please make more thank you
I've been flying BF 4.4 for a few weeks now, and am pretty happy with my numbers, but I of course had to put your expertise to the test. Here's my feedback:
I did not know that feed forward was not used in Angle mode. I disengaged it, and found no difference. I will fly without it from now on in Angle mode, as there's no need.
I have no black box, but found your filter recommendations to be much better than what I was using. The motors sound smoother, and they finish a flight very cool to the touch.
I'm going to experiment with my P-D balance some more. I may find something more in the process. Never tried it without I-gain, so I expect I will learn.
My minimum RPM is much higher by preference. It suits the way I use my throttle in Angle mode. 130 would be a tad high for most 2-inch builds, but that's my number.
On the whole, this is top-notch information; a typical Rosser Joint.
Thanks for sharing, Chris!
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
Thank you so much.
Instant thumbs up 👍
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.
In the previous videos you ised to turn off the dynamic D but is this 1 you didnt ? Any reason for it ?
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?
Great tutorial
At 3:33 when you turned on the rpm filter, you left the motor poles at 14. S/b 12 on that quad.
Thanks!
Brilliant.... simply BRILLIANT!
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
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 😅
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 nice videos! What if my older quad is still flying around with multishot, should i replace my esc's? For a better tune?
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’ve got very god results using dynamic idle and brake on stop function for esc..motors just sings now!
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
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
Guy is the KING
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?
Could you do a tutorial on using neural networks in predicting the optimal PID values?
You are crazy man! ❤
Muchisimas gracias por este video, Excelente!
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
