Betaflight 3.5 is coming out. Wait... didn't we just do this? There were just a few awesome features that the devs couldn't quite fit into Betaflight 3.4, but they couldn't wait for 4.0 either. So they've made a Special Release of Betaflight 3.5.
What's new? Dynamic Filter has been significantly improved. And Feed Forward is a thing. What's that? I'll tell you.
Betaflight Configurator version 10.4.0 is officially released. Download it here:
github.com/betaflight/betaflight-configurator/releases/tag/10.4.0
Here's my overview video of Betaflight 3.4 if you want to refresh yourself on what changed:

[@loflofpv6388]

@3:47 were do I download bf 4.5

[@JoshuaBardwell]

In the configurator turn on Show Unstable Releases. Change the pulldown from Release to Release & Release Candidates. 3.5 firmware version now shows up for flashing.

[@alfiekupper7916]

It was a joke JB you misspoke and said 4.5 not 3.5!

[@MrAlansage]

I was just about to say this lol

[@damonbfpv]

went way over your head that joke josh lol

[@Raqtor96]

Yea I was about to comment about the fast releases since 3.5 was so 2 minutes ago and 4.5 already :)

[@Illuzionizhere]

Hey Joshua, I've been watching your channel but this, somehow, is the firth Tim I'm commenting. I just wanted to say that I really appreciate what you do. I rely heavily on your instruction and appreciate your contribution to the hobby. Given that I'm well informed but still novice, I feel like I've been through all the noob experiences with moves included. Thanks for educating us, and keep the content coming! (Videos where you test things with stick position overlay are awesome and my personal fave) Happy flying! Bobby

[@quadifyrc]

Thanks for putting everything in one place. Love the 3.4 vid where you looked at the tuning recommendation difference from defaults, super helpful. Looking forward to the equivalent for 3.5

[@mrmurder75]

Excellent video, been waiting for this. Thanks josh. Been running 3.5 for a little while now but I wasn't too sure about a few things. This cleared it all up for me.

[@jonpacheco7581]

Loved your video and your humor. Thought I was current with all the updates and thanks to you now I know about the new config and all it’s new features! Also I noticed that the vtx smart audio is now fixed on 3.5. You definitely have the most informative content. Thanks!👍🏽🤙🏽😃

[@TMacFPV]

Joshua, I very much appreciate your patience in explaining these things in detail to relative newcomers to the hobby. Also, we all need a refresher now and then. Please don't ever lose it. Thanks

[@uavtech]

Great video; especially on thoroughly explaining FeedForward in easy to understand terms!! Helping with some testing, and if folks like the 3.5 Dynamic Notch improvements - fingers crossed they do! - they will love what is coming in BF 4.0 [in January... :-) ... take a day]. It is even more improved, but alas, again after the cutoff for 3.5. ... and since no one is commenting on the Butter bit at the end .... Good stuff. Fun to play with the drama. It is a hobby for most. So having fun is what it is all about.

[@mrmurder75]

UAV Tech bring on 4.0!

[@rodrigo207]

Just started watching some videos on your channel UAV Tech. Good stuff! A bit too technical for my limited knowledge but I will catch up. Keep it up!

[@uavtech]

Thanks Rodrigo207! Appreciate the kind word.

[@lievenvv]

@@uavtech Thanks for all your work! I have been enjoying your filter explanations/recommendations for a while now.. I've also been (casually) testing BF3.4 and 3.5 on my 68mm-120mm Whoops and micro's. I don't have any structured data for you, but my first impressions are that 3.5 is really fantastic. Cheers for that! (3.4 gave me hot motors, but I didn't know why...)

[@davidoff0921]

It is amazing what you guys doing.

[@scooterpie1143]

Mr. Bardwell, You are amazing. Thanks for this info and helping me make sense of what seems to be impossible to understand.

[@MavenFPV]

Very good stuff Joshua. Kepp doing it. Thank you!!!

[@David__]

Another great explanation Joshua + Thanks for BF devs for all they do to advance the hobby too :)

[@unitedelectrician4334]

Thousands thanks for the unseen hard work. You indeed teach me new stuff

[@NiteOul1]

I have a 3” build running a racerstar starf4 aio board with aokfly 1407 4200kv motors. 3.4 made the quad almost unflyable. Motor were extremely hot no matter what tune I put on it. This was not the same on another, more under powers 3” that I have runnin 10a escs and 1306 3500kv motors. I also have a wizard x220s that had no issues with 3.4. I decided to flash all three with 3.5.... just WOW! I left the tune stock on all three and just adjusted the my rates. They all fly amazing. My 3” racers are completely different animals now. Glad I saw this video though. As I just flashed them today, I was a bit curious about the new features. Thanks again! You are an inspiration bro!

[@jannesbosma9801]

Thanks , these BF updates you are giving us are absolutely excellent! I would really like to see you do more of these, and also specials towards more futuristic features like, flight controllers with F7 on 32KHz. I think you could add more value there.

[@MicroRCFiend]

Looking super healthy in this vid dude and dig the new gigs.

[@pedrogrieblerreche7402]

Betaflight 3.5 is bringing some really interesting features! Unfortunately the quad I'll be buying to start in the hobby is a 2015/16 quad with 2204s and a CC3D (I'm only buying it because it includes a Fatshark Attitude v2 :P). Soon I will modernize that thing... It's also nice to know you're working with Holybro for the Kopis 2! Ask them to give their customers the possibility to choose between the F40s and the F60s, it'd be awesome!

[@StiloNautica]

This was soooo funny!! Thanks Joshua, grts Rotorbird

[@legswithwings6473]

poor joshie... love your great work, keep it up! (its okay if you take a break i don't mind)

[@bsrfpv7828]

Thanks for the info i thoroughly enjoy your tech vids 🤙🏻

[@KGFlyer55]

Thanks again for clarifying new features!

[@mbycfpv8937]

I was waiting for this video to do it. I read the 3.5 notes and wanted to see what you said about it all. Flashed the jb f4 to 3.4 abs tweaked it so much with their notes on how to tune it flew like crap. Flashed back to 3.3 flies amazing. I'm gonna do the 3. 5 defaults 😁tomorrow.

[@Fliptality]

Jesse Wooten same here

[@Propstew]

I can’t thank you enough Joshua! I finally got my bird flying good and I’m able to make content! Can’t wait to try 3.5! Your 3.4 videos saved my ass :)

[@roanumali4366]

Your really awesome Guru JB and funny too with the last part wahaha hilarious....

[@fpvwing]

Sir! Sir! I understood set point weight! Great vid. Nobody does it better.

[@scottmarshall6766]

Us poor end users that are still learning to fly are getting whiplash Betaflight has advanced so much in the last year or so. I built a HelioSpring quad to try Butterflight and haven't had a chance to fly it yet. (and now I heard it's dead somewhere, wonder if my Helio will work on Betaflight), oh, yeah - where did I put that Quad I flashed with the Kalman filters? As overwhelming as the drinking from a firehose info feed is, it would be virtually unfathomable without your tutorials. Thanks for keeping up with it all, I usually watch these videos and let it settle in a couple days, then go back and watch it again. It seems to help, and even though I'm usually a few months behind, thanks to you, I have a pretty good grasp of it all most of the time. Looking forward to watching you run 3.5 thru the Kopis.

[@JoshuaBardwell]

The thing is, nobody is forcing you to upgrade, and if you do upgrade, the defaults probably are going to work well for you. So even though there are tons of under-the-hood changes, you should still be able to keep up... or choose not to keep up, as you prefer.

[@scottmarshall6766]

I know - they really fly great on defaults, but I have the 'can't stop screwing with it' disease. I've got a couple really good flying ones I leave alone so I can get stick time in, which is what I need much more than a better flying quad. One problem is I come from model airplanes and really enjoy building, but it gets expensive to always have a new quad on the bench. I'm finishing up this one for Rampage and stopping (for now...) Having fun so I'm not complaining. Thanks!

[@RCSurf]

lmao , 3 years ago , to now ha ha shh buddy enjoy the smooth ride. the advances in bf have been amazing . wait until you get BF 4.0 :)

[@rodrigo207]

3.5 flies great! I have one quad on 3.4 and another on 3.5. The 3.5 one needed, and still needs, a bit more tuning. But that quad always seemed to need more tweak compared to my other one. One thing I noticed is that propwash handling is better on 3.5, and I thought 3.4 was pretty damn good already. It took me a couple days to convince myself to give 3.5 a try because I thought there was no way it could be any better than 3.4. I was wrong, it is better.

[@weazlefpv5514]

That was awrsome man great video!!

[@Raven187FPV]

😂 actual lols at the end there. Did you hear about the new fork? Lubeflight. It's silky smooth. KY filter is insane.

[@PatentLobster]

Thanks Josh good video as always

[@tbcreative3703]

Awesome as usual 👏👏👏

[@shawnpatrick344]

THANK YOU SIR KEEP KILLING IT YOUR THE MAN

[@chucksandos8939]

Very interesting methods. Many thanks for expand it for us

[@traumhobby]

...the end :) ... Joshua you´re a real joker! Thumbs up

[@Sean-fs1sg]

Fantastic explanation, thanks!

[@Zugmunt]

The beta/butter flight banter at the end was great! Love it! Wahahaha!

[@WildpixFPV]

Thank you, Joshua! :)

[@p074rb34r]

Love your videos, and you helped me figure out why all my CLRF4S video kept cutting out on all my Armattans and personal builds! Keep up the good work, but I'm still upset about the Mach2 video transmitter I bought that doesn't work with Beta flight anymore. and I still fly my original Fuuton, I'm gonna install Rotorriot motors on it, cuz my Raceflight build never got off the ground...

[@michaelinmotion]

I run the Mach2 as well. Perhaps you missed the video Bardwell had, but you CAN still update to the latest BF firmware and still keep your smart audio feature for the older gen Mach2. Here's the latest 3.5 BF hex files: ci.betaflight.tech/job/Betaflight%20Maintenance%203.5%20%28AKK%20-%20RDQ%20VTX%20Patch%29/lastSuccessfulBuild/artifact/obj/

[@dr.sheldronecooper1786]

You are my freaking hero!

[@wareagleA5]

I'm already loving 3.4, can't wait for the new configurator and 3.5. The release notes, tips, and filtering advice are also great, BF devs are doing great work.

[@3-danything977]

So cool. Lots of good info

[@Mikebfpv]

Hahaha love it JB!

[@DangerDavefpv]

thank you very much bardwell... im using the 3.5 and im clueless on all it can do to improve my flying feel

[@someonespotatohmm9513]

just installed and mostly configured bf3.4 on my first quad today. Made sure it doesn't explode. Now i get to do it again :D

[@vissago]

The fortunate thing about the internet is that despite peoples abject unwillingness to be friendly and the demand for screaming and drama - you aren't obligated to give a shit about any of them :D keep doing what you're doing and dont let the drama queens get you down.

[@JustAskDave]

Thanks Joshua, I have learnt so much over the last week from your videos! I am new to quads (a week in) but not new to flying (been flying RC for over 40 years). I have a 140mm frame quad set up using the OMNIBUS F4SD and it flew OK after programming using your excellent how to set up from scratch video. However, a wire snapped off the receiver while hovering and it dropped about 3 metres landing upside down on cement quite hard. Now as the quad lifts above say 2 feet it goes into an uncontrollable roll to the left. Below that height it stable, as it approaches that height it becomes quite unstable and wobbles, once it hits that height there is no controlling it even with full right stick. I ran it up on Betaflight without the props and as the motors his about 50% the graphic of the quad in the first tab of Betaflight shows it rolling to the left even though it sitting still on the table beside me. Any ideas? I have updated it to 3.5 with default settings and the transmitter is at default except for an arm and a angle/horizon/rate switch. I am thinking that the gyro may have been damaged in the crash, though the only physical damage was 2 cracks in the very light weight prop guards. Cheers for any input, Dave.

[@JoshuaBardwell]

Something doesn't add up here. If the gyro showed the quad rolling left, then the quad would roll right in flight, to counteract the perceived left roll. But the bottom line is, you crashed it from 3 meters onto cement, and now it flies weird. If it hovers, then I think the ESC and motors are okay. If it tumbles out of the air, then it might be a damaged motor. If it rolls left as if you were giving it stick input, then I think it's a damaged FC.

[@JustAskDave]

Yep, same thoughts all around that I was having. Guess I will see if I can get hold of an new FC and see what happens. Thanks heaps for your thoughts and keep up the good video content!

[@JustAskDave]

OK, did some more digging, no issues with the software and asit turned out no issue with the FC either. The build instructions were a bit wrong in my mind, they had an o-ring below the ESC and one below the FC. Moved them to be above/below the FC and it now flies stable again though with a massive vibration. Whilst hovering for a couple of minutes one blade self destructed, so I think I know where the vibration was coming from! Now to source some new blades... Thanks heaps for your reply and thanks heaps for your videos, have learnt so much in a very short time.

[@jrkrgrsherman]

You are such a good actor.

[@JoshuaBardwell]

I'm gonna assume this is sarcasm.

[@trif55]

I literally flashed 3.4 to my quad last weekend, GG!

[@NanDaKai]

Thank you!!!

[@TheXanUser]

so glad i stayed till the end! wish they could align the config version numbers with the firmware version.

[@bisarowood]

"Feed forward" finally a tuning feature I understand ! coming from FBL heli

[@toddbeal4373]

Hahaha loved that ending man!

[@garylawrence4youtub]

Love the ending 🍴

[@t3g3lst3n]

Oh no, I'm 90% done setting up bf 3.4, now there are a new again... LoLz I don't want betaflight & butterflight, i want oilflight were stick centers are ever changing together with expo during flight and if camp (hover) to much in same spot it will reverse a channel randomly... ;) Nice video as always! Love the end.

[@UFOFPV]

Thanks JB

[@gitech7450]

I've got a thing on 3.4 with 1104 7500kv motors. Thought they where hot(er than they should be). Downloaded... flashing... Tnx for the heads up Josh! Will update when tested..

[@dabit4840]

I tinkered a lot with BF3.4, but I never managed to make it fly without a glitch here and there, and the best I could get was 'Oh, it is OK', but never 'Amazing!' The BF3.5RC2 which is on the quad right now is totally different. Went through a tuning session, ended up with fairly high PID numbers, verified the results with Plasmatree and the blackbox analyzer, and the quad flies sharp like a razor. Zero dipping, zero propwash oscillations, smooth sounding and cool motors, extra flight time, totally unimpressed by strong wind, and a magnitude more precise steering than I managed to get with 3.4 The only 'extra' thing I had to do was increase TPA a bit (breakpoint 1350, attenuation 0.3) to cope with oscillations at the upper throttle range where the (usually beat-up) props are starting to disturb things.

[@RADERFPV]

I'm pumped about the Kopis 2, for sure!

[@flo-ridafpv5713]

♡ that ending

[@DavidOwensuk]

Great video

[@campilottv]

I like the last minutes :-)))))))) - so coooool

[@lievenvv]

Yes, it made my 3" fly amazing! And yes, it cooled my motors down from 3.4. Even made my brushed Whoop fly great. Thanks, devs!

[@MrJarrod]

Love the butterflight joke. People get get so passionate about it. :)

[@pippifpv]

I want a kopis even more now. That is a nice racer.

[@pablofpv]

You made me laugh out loud! I feel your frustration ,I wish everyone just stop innovating ,I can't keep up........

[@williambarth5271]

It’s funny, look at butterflight now, 😁😁, great video

[@douglasyoung3992]

Always informative and truthful. If you ran for president JB you have my vote.

[@jleak4408]

aside from being an FPV savior legend, your also a really funny dude. thanks JB

[@zymurgyjwt]

Put 3.5 on my on my f722 and its great. Almost as good as my hello with butter.

[@B3NSipodtouch]

Very old version of beta flight just wanted to check out what updates there were two years ago versus now and love increasing your watch time

[@daggad02]

Great video. I am still on 3.2 tho...just lazy I guess but the damned thing flies sooo good ! :D

[@MrDally87]

The MacOS version of the 1.4.0 config. Fails to load the ports tab. Says “update req. “ any suggestions. Does it on 3.4 or 3.5

[@rogueFactor]

I wish I had access to the data but I don't tho if I had to guess betaflight is SHIPPING on more microquads at this point than full-sized quads as well as replacement FCs. Albert Kim's recent BF v3dot4 roast video showcases 3dot4's serious issues. When we can easily in under 15 seconds toast a $30 motor because of flight software, BF developers should be praised for the attention to the community and 3dot5 IMO is the answer to recent concerns especially in the micro quad area.

[@duckslave]

Really good explanation of feed forward and dynamic filter changes - but, as UAVTech commented - amazing things are happening with the dynamic filter. I've been testing each new variation, and the work of CTZSnooze and UAVTech is producing truly amazing results in terms of the accuracy and effect of the dynamic filter. CTZSnooze, in particular, has had some real epiphanies about how the DF should work, to the point where, in flying the latest beta variant today, I found that the Dynamic Filter performed like a magician in terms of exactly tracking peak noise from 150hz to nearly 700hz, and with no bandpass filter involved. I wish these changes could be incorporated into 3.5.0 stable, but, as UAVTech said, they are scheduled for BF 4.0 due to the feature freeze on 3.5.0. The really cool thing is that, properly configured, the new black magic works as well on micros as full-sized quads.

[@uavtech]

George H, you don't give yourself enough credit. Thanks for all YOUR efforts on testing. I'm the guy the took vacation why you guys were hard at work. and 1000% on: "CTZSnooze, in particular, has had some real epiphanies about how the DF should work, ... ". HE IS AMAZING!

[@duckslave]

UAV Tech - thanks Mark - but you guys are the brains behind the whole effort - I'm happy just to be a part of it and learn.

[@Sugar_K]

George H Ctsnooze’s eureka moments are almost daily right now. By the time 4.0 comes out the dynamic will be a greatest filter on planet earth

[@duckslave]

Sugar Kane - I couldn't agree more - hard to keep up with him, but worth it!

[@cJhudanich]

Great video, you never disappoint after a 20 min episode. I have a question about 3.4 and some of the 3.4 RC differences I found, whats the easiest way to ask you about them? Made a night and day experience after i found them, at least for me.

[@JoshuaBardwell]

You can email me or message me on FB.

[@heartofamericafpv5584]

Just a heads up, I was smoking a ton of motors and it ended up being because of my high yaw p gain of 105. I would break a blade off a prop and it would keep flying until a motor smoked.

[@JoeStanFPV]

3.5 is amazing... the fast forward feature per axis is sooooooo nice

[@conroy539]

JoeStan FPV is in iiiiii

[@exinfernnus]

Wow, F40 pro 2? Bring your good batteries. I have some on a slightly heavy Chameleon. The power is insane, but so are the batteries I have piled in a cement block near the garage. Thanks for the clarification on these new variables. Hohoho, yah, the ButterFlight thing, repercussions.

[@BOTGRINDER]

here cause of thumbnail

[@joelposthuma4473]

My 3" flew soo much better with 3.4.1 I previously had 3.3.3. I can't wait for 3.5 I hope it is out before I finish building my quad.

[@_bdub_]

Sorry to ask for help here in the comments but after flashing 3.5 my Ports tab is unavailable it says "Firmware upgrade required. Serial port configurations of firmware < 1.8.0 is not supported." Nothing is shown in the ports tab just this message, ideas? **NVM FOUND MY ANSWER ITS A BUG

[@brapppstar2314]

HELP! i cant seem to install usb drivers i have tried on 2 pcs now and still same thanks

[@KingPInAut]

I updated to 3.5 but now I can't control my Runcam split through the transmitter anymore :( Is that a known issue?

[@bazmatthews3717]

Awesome, you the Quad G

[@garycragg1]

I flew today on 3.5 .. yes i definitely felt a difference .. my quad was smoother and more locked in .. 3.4 was awesome this is better.

[@garycragg1]

love the honesty ... lol

[@M0rdH0rst]

I've noticed the hot motors on BF 3.4 too. Strangely I did not notice anything in flight or in the logs, they just got hot.

[@KrotowX]

Dynamic notch improvements and feedforward in BF 3.5 are definitely worth to try. Will do that by myself when rain will end here. In fact I should thank BF devs for freeing us from tinkering with stuff that actually can tinker itself. The next little breakthrough probably will be dynamic PIDs that will allow us to forget about PID tuning completely except some very specific cases. Other good thing in usage easing direction would be a setup wizard for board direction/motors/etc. like Kiss configurator have. Butterflight in general is same Betaflight with Kalman filter and flawed AKK SmartPort implementation. After filtering improvements in Betaflight 3.4 release I can't see a big reason to use Butterflight anymore. Although there are always someone who wish to be more different than others. Wish them luck in being alternative ;) Have no luck with rain at today too. However it gave me a little spare time so I'm now building 3rd racing quad on Floss frame.

[@ericmoore86]

"Oh well" LOL! Hey, thank you for all of your time sharing this information with us. I am fairly new and highly appreciate it, since I know nothing until you teach me. Could you help explain why my quad disarms when airmode is off in acro and I let it free-fall? Crazybee f3. Thank you again.

[@JoshuaBardwell]

If your quad is disarming check the Warning OSD element as described here: kzbin.info/www/bejne/hGnSfoB9Z9CgpNU

[@SuperBradley79]

I think it's only a matter of time til you appear on TBBT!

[@peterpunch1]

So at first I am interpreting your description of feed forward to be related to the term "acceleration" on hid devices, e.g. mouse sensitivity acceleration. If that interpretation is true I am having a flashback from my thousands and thousands of quake1 & 3 hours between 1998 and like 2012 were I ran both positive and negative acceleration in very fast paced gameplay jumping around the maps. It was wonderful once used to but a problem introduced on the years I used acceleration was that I could not run any other titles even recreationally without playing like it was the first week in front of a computer and it was hard getting back to after just a few weeks off not playing but sitting with the mousepointer in windows. If feed-forward = acceleration, do you think it could possibly introduce somethink alike when switching quads and components?

[@tinysfpv7105]

hi, Josh, I am getting an error from the ports tap I am using an omnibus FC and the error is this ( Firmware upgrade required. Serial port configurations of firmware < 1.8.0 is not supported) can you help please and thanks

[@BruceLuckcuck]

It a bug in the configurator and should be fixed later tonight.

[@tinysfpv7105]

Bruce Luckcuck Thanks

[@kingyfpv4787]

Me to buddy exactly the same thing :(

[@kingyfpv4787]

Bruce Luckcuck I hope it is mate thanks for the information;)

[@TM245]

I've heard of Paying It Forward. But now there's Feeding Forward? And we have to put Butter on our Flight? Where do we get the long and lat for the delivery?

[@fpvandgasrc4321]

Hey great video as always.. when is your house going to be in liftoff?

[@JoshuaBardwell]

Before the end of August.

[@peppebck]

I’ve learned ff before watching your video. I was hitting a wall and I made a fast correction. The reaction of the quad was way more aggressive of what I expected and almost crashed. Now I’ve learned why. I think I’ll lower them to almost 0.

[@JoshuaBardwell]

Well be careful because 0 is not "neutral". It will actually dampen the movement.

[@IceCreams62]

Do you know if with the new configurator for 3.5 the BLACKBOX EXPLORER will be directly available inside the conf like in Butterflight configurator ? A little feature but very appreciate.

[@joehamon9570]

Hey bud have you seen the furious fpv 2.4ghz true d module for Fatshark. Please get your hands on one of these long range an great penetration may be awesome I really need your opinion before I go all in gonna run crossfire for Rx link

[@RockTouching]

Fingers crossed 3.5 will fix hot motors on micros like you said. I'd really like to switch from 3.3 for the new features!

[@Seaweedaids]

Micros wont get hot motors on 3.4 if you run the same filtering settings. The defaults are more aggressive in 3.4 and 3.5, noisy quads might still need to enable some of the static notches.

[@fpvwing]

Sir! Sir! I understood set point weight!

[@quincydrones928]

I get a weird error message on the ports tab in betaflight and cannot configure the ports. Firmware upgrade ? What exactly needs the firmware upgrade now ? My computer ? The board ?

[@BruceLuckcuck]

It's a bug in the configurator that just got fixed. Should be a new version out later tonight.

[@mikebagnallshooting9818]

Everytime i follow KZbin tutorials the lay out and workings of sites needed are different to mine so i can't get set up the taranis plus of mine won't even flysky a micro help needed bad before I give this up

[@dave3883]

Very cool

[@cenabitednbfpv587]

so im assuming i need to toss out my pids on my 3inch quads and start overe? TBH I LOVE the way they are flying, should i even bother if i love the way things are flying????? Ill try it on one but damn keeping up with the devs is killing the fun i cant build and update quick enough all I wana do is fly in my spare time, why dose this have to be full time, i need to do music and fly, ill you just come do my pids n keep my ish ready to fly, like a lipo buttler????? ill up my patron hahaahh
