Betaflight 4.1 RPM Filter Setup | THE BEST BETAFLIGHT HAS EVER FLOWN 

just watched this vid again,,,,,,, only this time I was hammering the pause button so I could follow step by step and set up my last quad I will be building. She will maiden tomorrow rain or shine. Fly or Fry.

FANTASTIC! The three minute or less video with this longer version is by far the best How To I've seen. The short video was snappy, to the point, clear... perfect!

i just want to say thank you, thank you, thank you! as someone that only sets up a new betaflight quad every now and then coupled with the increased complexity of betaflight with vtx tables and rpm filtering. i have rewatched this video several times since you released it to help set up new quads!! you are awesome!!

Very helpful. Im getting over an fpv plateu now jumping in to learning more about filters to make me a better builder. Thanks again JB for getting me from nothing to full builds in under 5 months, you the man josh!

Thanks a lot for this amazing video, Joshua! I started with configuring my all day 5" quad for bi-directional Dshot and rpm filters. The result was really amazing: almost no vibrations, even in dirty air - very impressive. What a difference! After that I changed my 3" quads with BLHeli_S as well (using the JESC firmware). Thank you for making my flights so much smoother!

I set up all my quads this way. The best advice I've ever got. Much, much appreciated JB

Excellent explanation of how things work and what we need to do. I have a 5" build based on the JB budget build that I want to try this on. 👍 You and ElectroBoom, two of my favorite teachers of cool things. 💖🤓

Listen to Joshua. He's right. Betaflight 4.1 with the RPM filter is fantastic upgrade. My quads were flying quite well on 4.0.4. I didn't think I was going to be in any hurry to upgrade and be making serious changes to my setup. It feels good. It handles propwash better than anything I've ever flown. There just wasn't much to complain about. Then I upgraded and set up the RPM filter a couple weeks ago. I did pretty much everything Joshua recommended here: 1 stage of RPM filtering, 1 low dynamic filter, and bump the sliders a notch or two at a time. I think I am at 3 or 4 notches towards the "less filtering" side of the scale. I was amazed almost immediately. It felt about the same doing flippy flops and sharp turns. I did some of those moves where you fly forward, do a 180, and punch hard to go back the other way. That was just like 4.0.4 for me, so there was basically no propwash. Then I did was an S-turn over a tree. I did it as tight to the tree as I could, I waited until the last possible moment to pull out, I made sure I was falling right down into my dirty air. I wasn't gentle and smooth on the throttle. I punched the crap out of it. I couldn't hear any oscillation or see any in my goggles. There was a tiny bit of propwash oscillation visible in the GoPro footage, but it was impressive. Joshua is absolutely correct. It is time to upgrade.

I love the fact that I understand very little in your videos and yet I find them extremely interesting. I'll save this one for later when I learn to stop crashing Thank you

Good stuff, as always! Was already flying with RPM filters and it’s just fantastic! A world of difference for me!!

Happy to see you change your mind. I remember a video few mounth ago when you first try RPM filter...

I really need to get on this, I have been playing with INAV too long and haven't been keeping up with Betaflight at all.. Thanks Joshua..👍🏻🍻👊🏻

Great video Joshua, no detail left out but so well explained I'm sure even a complete beginner will be able to follow. 👊

Great tutorial JB! Taking the dive finally and setting it up. Thanks for all you do so well!

Joshua, another fantastic video! You've explained what I would consider a reasonably complex topic in understandable terms (again)! Thank you

Only been flying for 2 months, put jsc on my mob 6 followed by the filtering in this video and it flys superb. Thanks dude 👍

Josh. Your explanations are so clear. Thank you so much for all your hard work!

Thanks for your great video. I'm not sure if this will interest anyone here. In BF4 the RC command filter defaults changed from interpolation to filter and the new default filter requires Frsky transmitter to be set to 8 channel mode (9ms). If your transmitter is set to 16 channels (18ms) you get stepping of the RC signal which creates a lot of feedforward noise. The fix is to change to 8 channel mode or adjust RC filter cut-off to

Great job once again Joshua, this really got my chameleon ti flying great again after the rebuild

Thanks Joshua for this fantastic tutorial! I just revived my old SPC Maker 100SP that was literally tweeting from vibrations and with the configuration you proposed it is flying like never before. I use the HAKRC F3 stack and it works great with the JESC firmware. All is great again! I love this little quad :)

Thanks Joshua from the past....and future.....I’m finally putting a quad on 4.1 and this has helped tremendously

Thank you so much. I am still a noob and finally got the confidence to play around with this and what a difference, WOW!

Thanks for this video Joshua! I had almost given up on tuning my Gecko 3". I had spent countless hours trying to tune out propwash and vibrations. I scoured RU-vid and the forums trying out different PIDs and filters and I could never get it to fly great. On brand new props, it would fly okay. Once I got a ding or slightly bent prop, it would fly terrible. Yesterday I installed 4.1 and followed this video for filter setup and now it flys amazing - even on trashed props. My first flight was with a set of pretty beat up props and I could hardly tell. It flew better than it ever has with new props.

Oh I'm getting excited, I was kinda waiting for this video from you. I'll go JESC, 4.1 and RPM filter... (I hope) 💪

For motor temps I would use a laser thermometer comes in really handy anyway . Great video josh I learned a lot might just give this ago thanks mate 👍🏽😀

Love it bro , thanks so much for the straightforward understandable information, been waiting for this video, much love

Im running JEsc firmware. Thanks for sharing, always a great stuff from you bro! Have a nice day!

Honestly, you are my favorite youtuber right now💯

I've been flying for about 6 months and I've learned just enough to be dangerous and get myself in trouble. I feel lucky to have this guy explained to us what the hell's going on. I should just be flying and not watching so many RU-vid videos

I don't know what my life would be without you ... You're a very good teacher ... Wow And look, my English is a little precarious ...

Been on the rpm filter for month. Love it

I used BF 4.1 and JESC on my 2.5" Tomo EvoHex 2.5" with BLHELI-S ESC's and which was almost unflyable due to vibes. Now it flies awesome!

Joshua, thanks for the video. I just tried it on a 2.5 inch quad and wow it was like night and day. I noticed much less jello than before to boot!

Excellent, done that on Blheli-s perfect and awesome. Thanks again Joshua for the community.

Thanks Joshua! Cant thank you enough for how much you have helped me.

I am still running betaflight 3.5. Something. Thank you for the information I have been waiting for 4.1 to upgrade everything.

Go Joe! I'll wait for stable 4.1, but I've already purchased the licenses for the jESC - just to support the developer.

Okay so your suggestion was incredibly helpful. Strangely enough the FF values are killing me from default. Was getting a crazy bounce back no matter how high or low I put the PIDS. So far stock PID but lowering FF to 60 across the board has this bounce back to a minimum. Sounds soooooooo clean!!! Never heard anything like it until now. Your the man JB

Well done on this Vid Joshua, keep up the good content

All set up ready to go. Thanks man!

I had a amazing flying quad that took a hit to a motor that made bearing replacement necessary. However, after replacing them it never flew the same. Horrible vibrations. This saved my quad and put it back to its original flying grandeur. Lol Thank You!!

Great tutorial, Thank you! can’t wait to try rpm filter on my quad! 🚀

Awesome. Been waiting for this. Thx Joshua.

Just changed my hummingbird f4 pro to 48 khz, and did all the rpm settings. Also used the updated settings on jescs website for d notch settings. Flys even better now, loving it.

I am a newbie at this. But I like to tweak so I installed Jesc on my UR85HD and followed the settings shown on this vid. I left the "Gyro RPM Filter Harmonics Number" on 2 and the sliders on default and it was terrible. Prop wash and vibration all over the place, but once I have set the "Gyro RPM Filter Harmonics Number" to 1 and the filter sliders to the red area (1.4) things started to improve. With the sliders both on 1.7 the UR was flying like on rails, tomorrow I will test the sliders up to 1.9 or maybe 2 I can't imagine it improves more but who knows. Thanks for the tutorial!

Really worked well. At first quad was worse, then as sliders moved to right all oscillations disappeared . Yet another excellent explanation !!!!

It is soooo nice that BLheli 32.7 is finally out that you can flash right from the BLHeli_32 configurator (FINALLY!!!). And awesome job breaking it down. You lay it out so nicely.

Good stuff (as always). Thanks Josh!

Good God! Thanks JB! Almost completely eliminated prop wash by just doing this! Ooooooo yeah! Thank-you thank you Thank you! Your an angel!

Thank you for the complete walk through :)

I love the hyperlow vert v2. Glad you swapped to it from them marmotte.

Thanks JB, this is super helpful!

"Joshua Bardwell your my hero..." ....... thanks for all the knowledge good sir!

Thank you for the video, as always really clear !!

I thought my Chameleon flew great with 3.5 but since i upgraded to 4.1 I cant believe the difference in how well it flies!! I wasn't gonna ever update my kwads because I liked the way i had them set up but now I need to update all my FC's to accept 4.1 since my other kwads have Omnibus F3's. Gonna be a nice winter for upgrading!!

Josh, I’m really happy you like it - and even more happy that you got it installed in 3 minutes ;-). The main improvement in 4.1 is that bidirectional dshot is now easy enough to setup that everybody can try it!

nice video for beginner,Thank you very much!

you make it easy! Thanks Joshua!

I can confirm that Joe Lucid custom firmware for BLHELI_S esc's works great. I flashed 4 spedix ES30 HV's with the custom firmware which cost $5USD and then followed Joshua's video tutorial above and it's all working perfectly :) Small price to pay for rpm filtering but worth it

Thanks for your diligence, as always...btw, what about forgoing turtle mode, setting ESC's to Multishot (faster than Dshot), running 8k/8k w/ separated motor PWM from PIDs, running motor PWM of 500...much less noise, and latency, allows less filtering, and CPU load...and better overall performance. ✔👍👌

Awsome, when i build up my qwads again I'll definitely use it

thank you man! i m configuring a 3 inches cinewhoop

Thank you for this information and great explanations :)

You helped a lot! Thanks!

I'm updating all my bugs to RPM filters, with Jesc Configurator. thx

Thanks Joshua for the tutorial and great tips, I am going to test these settings on my toothpick! Nice greetings!

Gonna have to build a betaflight rig to test it out thanks JB

Thank you again for this video!

Thanks again for another great tutorial!

Freshly built 7" came with 4.0 on it. Default Filters flight was not great and motors were warm to touch after a pack. I upgraded to 4.1.7 (to avoid 8k lock) and if felt so much better that I ripped a full freestyle pack over asphalt (maiden rip) and when I landed the motors were cool to the touch. Mind you, this is a 7" 6s. Thanks Joshua!

just followed along and set mine up just like you said, im pretty stoked to try it out! also still trippy to watch an instructional video and the host has my face on him haha.

Did this on my cinewhoop, propwash is almooooooooooost gone now. Good stuff!

thank you! will use that knowledge soon! greets from Poland! fly safe :D

It works fantastic for me. Cleaner props sound, less prop wash, but most amazingly the motors are not even warm. 4K/4K/DShot300

Just did this for my Eachine Trashcan last night and had a little fly around the house and motors stayed completly cool, was originally running 4.0.6 with AndyRC's tune which gave me really hot motors while doing the same thing. Only thing I had to do was drop to 2K/2K with Dshot300 (Dshot150 was giving 100% errors in the motors tab), not sure if this is recommended but seemed really stable on the indoor flight, need to wait until the weather improves a lot before I can try a real flight.

I did all my 5" quads and my 3" Diatone 369. Your setup is amazing on all my quads. Just expressing my gratitude again Take care

Tank you for the quick replie Sir

I stand by UAV Tech here. Great job explaining it to simple minds like me. 👍

Its really good.. I updated all my quads.

Ni e job. Thanks for the how to. It was a grear help

Please inform me of how to support your channel. You have are god sent to me. I just started fpv less than a month ago and all this terminology, in the beginning, was like a foreign language. It's still quite a bit to grasp, but with you in my corner helping me step by step I feel confident that I will get a handle of this stuff eventually. I feel bad learning all of this and not contributing to you. You rock!!

Great video thanks for this.

thanks for the help man!

JB, not sure if your live shows have been taking on guess yet. but it would be great to see Mark aka UAV Tech and you on a live stream focused around Filtering & Tuning and everything that goes with it.

For heavy-ish freestyle quads that have bounce back, try switching I term relax type to gyro and reduce the iterm relax cutoff to 11. Reducing feed forward will help smooth out your moves as well, since betaflight 4.1 can be a little too snappy with the new feed forward system

Thank you sir! You are the best.

also regarding the magnet number, i looked on the motors website ..look for Configuration: 12N/14P ...thats how i found out i had 14 magnets instead of counting them

Set up a 3 inch with this new wizardry, and its insanely good!!

Thank you Josh ❤❤❤❤❤

Great Info. Thanks Bro..

Thank you soooo much!!!

devil is in the details... that little green tape lmao! good job JB

Thanks man God bless ya!

I did this to my 3inch geprc Sparrow, and now it flies so much better! Propwash is gone 😁

Thanks!

Thanks

I had enough parts to build a quad. So I put together a acrobrat and put 4.1 with rpm filtering. Honestly I dont feel a difference, but to be fair I haven't flown it enough to make a honest comment. I have a matek f722se, a hglrc 32 35amp esc and f22 3750kv motors running 3056 props on 4s 650 tattu regular bats. I set 8k 8k with dshot 600. I need to run tattu r-line 850mah which seems to have less sag then the 650 regs. My initial feeling is that it sounds smoother and flys clean. I set it up as JB suggested and the motors are warm not hot. I did use some damaged/rough props to just be safe. I feel very comfortable upgrading all my quads to 4.1 with rpm filtering. 10.6 gui is awesome. Cuts down on cli commands from vtx to rates. The devs are kicking ass! I do believe Joshua is right, no reason not to upgrade! I was able to force prop wash, but I haven't really fine turned and you can force prop wash on any fine tuned quad. Awesome tutorial, Thank you Joshua!!

I'm upgrading. Cheers JB. ✔✔🍻

My quad fly perfectly on 4.06, when i update with rpm filter, i have very rough idle and motor get hot no matter the how high or low i set the filter slider. (no flying, just idle) 1700kv, 6s

Great, thanks!!
