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!

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

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.

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.

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

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.

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!

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 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?

@joshuahenriques3224 Год назад
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
