nice tutorial! quick tip re Master multiplier. the ripple is oscillation (you'll see it in the dterm traces). Notice that it lower on pitch because there's more weight along that axis and it requires higher relative gains than roll, and you can see this in the latency difference between the two (pitch has higher/slower latency). what you wanna do in that case is bring roll only down until that ripple looks about the same as on pitch and their latency is approximately matched. then you know you have equal responsiveness on both axes. you'd do this by dropping the MM until roll only shows a small ripple then boost pitch PI and D to where it was before dropping the MM.

Great advice thank you Brian! Edit: Other question to you @D3B8 are the filter settings unchanged? I have seen there are presets for super clean/clean/normal/noisy etc. filter settings and wanted to ask how do we judge when its already noisy etc :D

This was perfect showing the cause and effect of the changes made. More of this please! 🙏👍😁 A video series building on these principles would be great.

Great tips! I do my tunes differently, but have always been curious how everyone else does their builds, and I love to test everyone’s methods against my experience, and sometimes integrate new ideas. I never drop I or FF as I generally know where they will end up on the build I’m tuning, but am curious to try single value, instead of my ratio relationship tuning method. Cool stuff! Thanks.

@albertatlinguasoft Год назад

First of all, thank you a lot for your tutorial. Your quad is clean, why do you need so much filtering (I think you have defaults)? Do you use RPM filtering? Did you try to disable Gyro LPF and Yaw LPF? What values do you see in PIDToolbox -> Spectral Analyzer -> filter delay?

@camelisator Год назад

Very good video, I tune the same way the only thing I do diferent is no dmax and I tune the FF to always have P term helping a bit. I find that in slower roll/pitch move it fight agains each other (like in the video at 17:25). I see it as FF is a P term helper not a replacement. Keep it up, it would be nice to see how you tune the filters 🚀🚀

@JevinW Год назад

That’s a good way to put it with ff being a helper rather than a replacement for p. But yeah man I appreciate it. I do plan to go more into depth with quad tuning in the future 👍

@sommmathechamp5801 8 месяцев назад

i just found out that if you start noticing more and more oscilations as you push up the master multiplier, try lowering i term relax to middigate the oscilations coming from p term especially when anti gtavity kicks in. my master multiplier is at about 1.4, when id punch out it would go berserk with oscilations, the blackbox log showed p and d oscilatin in phase while i term was inverted, which means the quad was struggling to meet that setpoint, the antigravity feature was placing on it. so i lowered the iterm relax from 25 to 5 and that practically eliminated the issue! also antigrav gain is on 1.5 since my iterm is already crazy high, i might lower it

Thanks for this video! My usb port is quite hard to reach since mines a waterproof build. Is there a way to do this without the Blackbox analysis? Or should I do this the old school way and adjust the parameters after every flight? My fc has bluetooth

@JevinW Год назад

I believe you can blackbox off of the speedybee app but it’s not too reliable from what I’ve heard. If you still want to get a tune going without black boxing, you could always just raise the master multiplier up a bit and call it a day.

@warmachined3472 9 месяцев назад

Being new to Beta flight how would you set PID for minimal motor-controlled orientation and how would I run servos. Just want the motors for thrust I have servos running the roll pitch and yaw on an experimental system, but have yet to figure out a way to configure them. My receiver is a Flysky FSia10B. I am running the rx1 pad and using serial receiver via ibus. Can I use the chanels on the receiver to run the servos?

@warmachined3472 9 месяцев назад

Oh sorry, controller is a SpeedyBee F405 v3

@Steve-hd2wm 4 месяца назад

You may be better with a different package if your trying to control servos. There is this option within betaflight, but as I understand it this is quite basic. For a great guide on the latest release of betaflight head over to Joshua Bardwells channel. His guide is split into each of the options making it very easy to find the info you require without watching lengthy videos. Also have a look at the software used for flight control on wings and planes. I know they drive servos direct from the receiver but these are quite large that's all I really know on the subject. Hope it gives you a few ideas and avenues to progress you experiment, keep on innervating and I hope you get it flying soon. 👍 Wow! I have just had a look at at your channel going to be a long term project getting it flying but I'm going to keep watching and subscribe. I would have thought you would want your PID loop altering the speed of each motor to maintain a level hover. I don't think beta flight will be able to keep it in the air by itself, as I'm guessing your creating thrust by way of servos on the ducts? Beta flight has been developed over the years focusing on FPV racing and freestyle quads. There options for other motor layouts away from X style frame. But I think on larger lifter and camera platform drones other software is used.

@ciaofpv5520 Год назад

Curious why you didn’t bother balancing the latency & ratios between axes prior to running mm test? I have a slightly different approach when I tune (always learning!), with an emphasis on balancing the latency between axes, prior to running up mm for latency reduction. Brain pointed out recently that what a lot of us have come to recognize as an over damped situation (rises to 1, then quickly undershoots and recovers) is actually the beginnings of an oscillation on that axis, relative to the pids on the other axis (typically roll relative to pitch, if I understood correctly).

@JevinW Год назад

That's actually a good point about balancing the latency ratio's and I wish I would have mentioned that. Personally I don't do it because the difference is so minuscule but then again, you got me thinking as I'm typing this lol, having consistency is probably whats best. I don't believe that means the start of an oscillation just because that scenario can happen even on stock pids.

@ciaofpv5520 Год назад

@@JevinW I think his point was relative to the other axes. I don’t want to get to technical, but I think it’s worth a look the next time you brave the murky waters of bbl/PTB. Just bring a 🛟 so you don’t drown 😅

@pbshooter100 Год назад

Thanks for doing this. I was able to glean some knowledge here which was good but some constructive criticisms if I may. 1. Overall the pace of this video is too fast, speech, mouse movements, screen transitions, shifting from app to app, everything really is very hard to follow due to the speed. I know that short videos are better but if the pace is too fast to comprehend then it doesn't matter. 2. Need more attention to detail, while there is some attempt to explain what you are doing and why in the end I came away with more questions than answers. For perspective what I learned from this video are the SW tools that can be used to tune things and the rough overall process that one needs to go through to do it. What I didn't come away with was any practical idea on how to actually tune on my own as there are too many details left out. Perhaps that was your goal all along, don't know. I know tuning is a complicated process so making a how to guide is hard, iI get it. Thanks for the attempt at it. As for me unfortunately I can't find this video that useful as I didn't walk away with an enhanced ability to tune i.e. I'm no better off after watching the video than I was before watching. Hopefully you will take this the right way, not trying to be negative, just providing my perspective. Cheers!!
