Just the kind of content I like. You educate for knowledge, not for "just do like I did and get over with it". Fantastic! About the notch filter - I think setting a really narrow width filter around 205MHz (in that specific example) and show how it splits the noise band could really go a long way in terms of education and understanding and just a good match for the way you explain things :)
Wow Mark, I have truly always been interested in the more technical side of quad building and flight characteristic setup, but am sad to say that none of many of the Blackbox videos gave a true and defined understanding of what exactly all the terminology was and what precisely was going on.. Joshua Bardwell certainly provided a better understanding and got me dabbling(thank him so much for everything) and at least fiddling a little with filters and blackbox logs, however I still feel I was just kind of trying to teach myself and figure it out. Your channel seemed technical, the theory you set out, but DAMN, after i dived in and started watching, I found just how amazing your explanation is regarding this subject....Sooooo easy to understand! :) :) Thank you so much for making such incredible content, i will certainly refer anyone I know interested in this subject to your channel. Thank you thank you thank you, MY MIND IS NOW SO MUCH CLEARER, thanks for sorting the mess out... BIG thumbs up!!!
Super nice video and explanations! Looking forward to the new PID tuning video! Just a small suggestion: please consider changing your on-screen text font to make it more readable
i love the sliders. this video was super informative. i would go to 4.1, the only thing is when the final comes out i have to remap 2 motors. no biggie, also no since in trying to tune a 4.0.5 right now. it flys great on default till 4.1 is released.
Hi Mark, any chance to get BBE 3.4 running on a Mac with an dmg-package? Or do u know when it would be provided? Update: I created a DMG for MacOS. It works for me
Mark, was there a rpm filter activated or not? If so than there was a lot of extra filtering. Second question I have a very very small spike at 100hz amplified by dterm. I have put a dterm notch 100hz & 10hz width. The spike is completly gone, is this approach okey or should i hav put that notch on gyro instead?
Thanks a lot. Does the slider will be also in OSD ? Else, I will have some holiday, and I really love to participate to BF. (First it will not be a slider in OSD, but just a value in %)
@@uavtech Thanks for your reply. So for others also new, I was looking for the red "heatmap" style chart. Turns out you just have to go to spectrum chart (the view with the green into red spikes) and then from the top left dropdown select Frequency vs. Throttle. Hope that helps someone.. Took me a while to figure out haha.
I've been real happy with the tune I got on my 5" quads after learning here. But i have a question - I'm just about to start tuning a 7" - just wondered if you had any tips...
Look at balance on the props. 7" props are not well balanced it seems and at that size it really matters (pretty big). Then log and tune according to principles. That is what i would do.
I'll incorporate these Fundamentals in my daily pray to the Kwad gods: *F.1: Dyn|RPM - Kills motor peaks (diagonal cloud)* 6:12 *F.2: Static Notch - Kills resonances (vertical clouds)* 6:19 *F.3: Lowpass - Kills ambient (amorph clouds all over the place)* 7:00 Maybe a lullaby: if your motors are too rusty add some Dyn... if you have a shaky rooster add some notch... and if you are full of random noise, try some lowpass, who knows it may be fit
Anyone knows what a decent phase delay would be? I’ m getting about 6ms according to PIDtoolbox, is that bad/medium/good? This quad flies quite well, so I’m guessing it’s not too bad, but I’m interested in your thoughts.
For some reason my board is only logging the first arm sequence of a flight. So if I arm to do a sanity check, disarm and arm again I only get one log with nothing in it. Nevertheless the flash seems to fill up, but no files to download. Does anyone know what is causing this?
@@uavtech I found the answer to my question on the propwashed website, the other logs are available through the dropdown above the legend :facepalm: So now I finally know what that is about :-D Keep up the work, it has helped me a lot to try and get the best tune for my 6" (still working on it). 5" inch just flies great without much tuning. Could you do a video on how to tune 6" and 7" for long range smooth video? Stick response is less important, however motor vibrations, frame vibrations and the ability to handle wind buffeting are very important.
I can , but it is the same principals. Maybe more heavily on the filters, but that is about the only differiential. Still need a tight PID tune to handle wind gusts.
As the filters are mathematical, would it be possible for someone (smarter than me) to write some software to simulate different filter strategies on an existing log? That would make it a lot easier to test filters without having to go and fly again.
Yeah, just takes getting the transform equations into a form (even Excel) with the raw noise to see how it will attenuate it as you move stuff around. It is the next step in our evolution here. We have come a long way over the past 2-yrs in more wide spread understanding of filter delay and attenuation, but mapping it on to existing data is still needed.
@@benaresq , no. Not really. But to do a simulation that runs through a log of raw noise over time. Good luck. Can be done, but outside my pay grade. I doubt anyone would take the time to make that software.
Great videos, really helpful... But... No such word as "irregardless"! The word is "regardless". And "Axis" is pronounced "Ax-iss", not "Ax-ess". Here endeth the English lesson, LOL.

That awesome dude deserves far away more love from the community
Happy you are getting new videos again after the summer break. Always learn some technical stuff from your channel! Excellent job!
It would be cool to see the results of your recommendations, something like side by side comparison :)
Yes. Folks always vanish after. Problem solved. They are happy so i never get a log back. Will make a note to grab this one.
Yep, second this suggestion.

“The Professor” Mark as always you rock!
Finally some sliders, looking good! Thanks as always.

Great job with the videos. It's very interesting when it comes from you.
Super interesting as usual. How do you get that BBE view in the beginning of your video? You mentioned a link but it didn’t show for me.
Tiny.cc/uavtech
Excellent video
Really looking forward to the new blackbox version. By the way, the tiny.cc URL you're showing is wrong, you have to use lower case letters.
Number 10 on likes list. That’s for the vid. I learn so much from you. Thank you

I think RPM was on, but not sure.
I like D-term notch. Less lag on the signal to P-term.
If a light quad, note prop wash goes up to 80 to 100hz.
How did you get that red noise graph?
Latest BBE MAster build. See tiny.cc/uavtech to download until the next official release of BBE.
@@uavtech I didn't see the pull down for type of spectrum. Thanks.
@@aowi7280 , make sure to unzip and run BBE exe from the unzipped folder.
@@uavtech Oh, so it's windows only for now...😭😭
@@lajulasse4332 , they will release soon. There is a mac version around let me find it.
are the slider labels backwards? more is on the left and less is on the right and when you move to right it increases the multipliers
Depends on how you look at it. Moving to the right is less filter (higher numbers). Moving to the left is more filtering (lower numbers).
Thanks a lot.
Does the slider will be also in OSD ?
Else, I will have some holiday, and I really love to participate to BF. (First it will not be a slider in OSD, but just a value in %)
Not sure yet. I think not, but would be nice.
I cant find how you got the 2d spectrum analyser on your BB explorer
Need newest build of BBE. 3.4 build at tiny.cc/uavtech
So i got the old .json to work with the workaround in the ticket above. But the specturm analyzer view is still a mystery to me.
Click the buttons in the legend. It will do a spectrum on whatever trace you click.

What is the Blackbox Explorer Version you are using?
3.4.0. You can download at tiny.cc/uavtech
I'll incorporate these Fundamentals in my daily pray to the Kwad gods:
*F.1: Dyn|RPM - Kills motor peaks (diagonal cloud)* 6:12
*F.2: Static Notch - Kills resonances (vertical clouds)* 6:19
*F.3: Lowpass - Kills ambient (amorph clouds all over the place)* 7:00
Maybe a lullaby:
if your motors are too rusty add some Dyn...
if you have a shaky rooster add some notch...
and if you are full of random noise, try some lowpass, who knows it may be fit
Learn it, Live it, Love it!! 😜

If it is flying good, don't worry about it.
Wait how'd you get that overlay of the pid tool box on black box ? Or Am I to drunkn? I got bbe 3.3.1
You need a newer nightly built at : tiny.cc/uavtech
@@uavtechThanks! Okay i got the nightly BBE from your link. But not sure what i press to get that Pidtoolbox overlay in the background. stooped.
@@zoobydooby2302 , click any trace.in the legend. It will run an spectrograph of it. Then maximize that and look in upper right.
Is there a phase delay calculator in the configurator based on our current settings?
See tiny.cc/uavtech for a.Phase Delay calculator (Excel files at root).
Pretty interesting, dude! Thanks! 😃

I do like the looks of those sliders the numbers always get me messed up
Yeah, less focus on the numbers and more on slider positions. It is very nice!
As the filters are mathematical, would it be possible for someone (smarter than me) to write some software to simulate different filter strategies on an existing log? That would make it a lot easier to test filters without having to go and fly again.
