Thank you so much for this video. I have my quad with blheli S flying great, thanks to your hard work. I paid the $5.95 and got the esc's licenced. Flashed the firmware, and telemetry. Now my quad chimes some star wars theme music on startup, and flies better than ever with your recommended set up. Love ya Joshua, thanks again.
Thanks Joshua for another super video! I really appreciate (as a German) your clear and simple enough English. My Comment: On a MAMBA DJI F722 MINI MK2 I've got too many errors with bidirectional DSHOT 600 and 8k/8k. Better and good enough DHOT 300 and 8k/4k.
Yet I do not understand where this value comes from. For instance, I have 1750KV motors running on 6s (22~24V) so at max throttle it means 640~700Hz for the fundamental frequency, and multiples of this for harmonics... Joshua, could you explain why 350Hz is relevant? (Thx a lot for your work BTW, it is an amazing contribution to our hobby!)
Seems like a full loop feedback using the gyroscope as a means of full control of the motor current/commutation strength and thus controlling the vibrations/phase between the 4 rotors to also minimize said vibrations. Not surprising the motors run cooler and thus more efficient.
I have a drone that you tried a long time ago, GX210, and it has always gone very, very fast. I don't just do freestyle races and I want it to slow down. It is touching the stick and it comes out like a rocket. By the way to go from version 4.1.5 to 4.2 you can save the basic configurations with diff all and then import them to 4.2 to avoid having to reconfigure ports, levers, motors, ... etc. Thank you
Thank you for all your informative and easy to follow videos. Your vids links should be printed in all the instructions manuals. Love your vids, Thank you Sir for all your help.
This is where I start getting it finally! God bless you sir, I’m off to the field tests) After 4.2 mentioned more sag effect on hi throttle causing low v alerts... I guess the rates must be corrected.
Thank you for sharing your knowledge. I am noob and learned a lot watching your videos. I am waiting to see tutorial videos on cinewhoop drones full pids setting for smooth and unrealistic footage for professional video makers
I still kinda wish I had time to make a Configurator Wizard that just has a getter to pull things off the community presets depending on a few things. The defaults for 4.1 are not as good as the 4.2 defaults are going to be, but the practical capability has been there under the hood, but not really very accessible. Some of these make sense to make as adjustments from defaults for almost everybody - but defaults still have to withstand 90% of setups, and usually the most strenuous ones are porky freestyle quads on 6S that may have a bit of frame resonance... The timing improvements, sag comp, and actual rates are the real selling points behind the scenes, but a lot of the DBoostGain/Advance and Dynamic Filter changes to defaults are a bit part of why the performance has just gotten better out of the box (very much enabled by timing improvements as far as notch Q that works).
FF_Interpolate and RC Smoothing (set to high values with biquad) are basically 'the' cine-hack. Combine that with the CTZSnooze Cinewhoop Actual Rates, and people would be pretty blown away with how smooth that is, even for ham-handed goofballs like myself.
As somebody who races primarily, I'm a fan of slightly lower sag compensation - picked up 70 as a recommendation from Furadi, and liked that quite a bit more. Still gives me at least 90% of throttle output off the hit, but covers up sag until I'm starting to get under the 3.5V threshold. Downside - if you over-push with it, the quad flies great until it doesn't, and I've been a bit mean to batteries running 100 on there.
Thanks for this. Betaflight 4.0+ has felt jittery to me even when I have FF set low. I’ve been flying Emuflight for the last couple of months because of this. Gave BF 4.2 another try with the suggested FF interpolation set to Averaged 3 and it’s been much better. Think I’m sticking BF.
I have a GEPrc rocket with Flysky for DJI and previously set up with betaflight 4.0. I purchased, (because of you) a Beta95x for DjI fpv for DSMX. I attempted to bind and set up in Betaflight. 4.0. A notice told me that there's an upgrade and to click on that.. I installed the upgrade and attempted to bind. Betaflight never saw the 95x. I tried to connect my previously connectable GEPrc rocket! Now it would not recognize that. I downloaded the virtual USB drivers and tried again..no luck. I connected my analog quads using a micro USB cable....it connected automatically, immediately! Blogs suggested that I switch C-cables to ensure that I'm using one that transmits data, not just charging. I did that. In fact I bought three different cables all high end and none of them worked. Do you have any suggestions, or should I simply install the old version of beta flight..? Thank you. Ken!
Scared not upgrading yet but will do soon.. I’m still to new to be fiddling with all this stuff. However my Tinyhawk Freestyle is a little bouncy but I will deal with it. Plenty of your other videos about how to fix it with the pid settings but I just can’t figure it out. If you have a great Pid set up for Tinyhawk Freestyle send it to me if you could , That would be great.. I actually did my maiden flight after doing a few mods and I haven’t even tried to go mess with the pids. Like I said I have watched your videos but freaking out a little about what to change and when.
Wait we can do 8k / 8k on an F405 cpu now? old video said do 4k/4k and cli shows too much cpu cycles being used on an f405 cpu. Did you mis-speak? is that correct?
I checked Betaflight source code and as far as I can see -- it uses the Mahony filter for attitude estimation. As far as I know, accelerometer data is used to compensate gyro bias drift in the Mahony filter. So if you turn accelerometer off you will probably start feeling this effect of non - zero gyro bias. Maybe it is not a problem for acro mode and you will not notice it. Does anyone know this? Can you actually feel the difference with accel on and off for acro flight? (I don't have any quads yet, just interested in engineering stuff)
Hi Joshua and thanks for the many entertaining and informative vids. Helped me alot. I am Very new to this and have a couple of drones (TH2, Mob7, Cygnet3 pro). the cygnet has 3.5.7 and it seems I can only use BTa config 10.5 to flash and fiddle with. The others have BT4.x and I can use BT config 10.7 to alter but can't seem to access the 3.5.7 easily so am always reinstalling Configurator ver 10.5 or 10.7 back and forward. Is it not possible (should be) to have both installed at once? BT 10.7 only sees BT4.x and not 3.5.x or I can't flash with it.... Ideas/thoughts? best regards ian in NZ
Knocking off Accl, barometer, & mag on 3 of my f4 quads and setting D-shot to 600 allows 8k pid loop. Always shows 8000 on all three parameters in CLI and they fly GREAT !!!
Nice video again but I am having problems with bidirectional even with safe "tasks" and Id like to ask what is a good setup if I don't use bidirectional...it was like having random slaps in the air at the yaw axis... Plus, even disarmed, the quad was consuming 1-2 amps...
So ... I tested rpmfilters ... and my quad still flies better and have better feeling with one lowpass on gyro and one on dterm and no notchfilter & rpmfilter than with all this fancy sliders tuned fully to the right, default filter settings and rpmfilter on. Offcourse I pushing more noise to the motors but they dont go hot they dont go even warm ... What now ? I think something is broken in my build ;)
Thanks, Joshua! What about the filter settings for a 3inch cinewhoop? Any different from what you recommend for a 5-inch? Also, shall we set number of harmonics filtering to 1 as well in BF4.2?
hey joshua - is it possible to get bi-directional d-shot running with kiss-escs? I find it incredibly hard to find information regarding unusual kiss-setups, sorry to bother you with that :/
Hey I flashed my escs to bidirectional blheli s with the blheli m configuration app. Once I enabled bidirectional dshot and my motors spun up and smoked instantly
Okay so I JUST got a Tinyhawk 2 Freestyle, and installed Betaflight 4.2 (no previous versions because this is my first quad), saved the original configuration, flashed my Flight Controller to the newest version with chip erase (original was 4.1.0 Oct. 2019), and pasted the original config back onto the flight controller. Everything seems like it's how it should be, but will this affect me like Joshua is explaining.
2:00 Every quadcopter can run bi-directional and rpm filtering? Even ones with BLHeli (non-s) ESCs? What about the Dshot selection for the aforementioned ESCs? Just asking before I toss all of my Littlebees.
Something bazaar on mine. I have everything set in Betaflight and all seems to work fine including running motors manually with the master slider. However, when I unplug from Betaflight and bring the quad alive with the radio, hitting the arm switch; the motors speed up well over idle and I get a vibration in the whole quad. I don't have angle mode or level mode set up so I'm not sure whats going on. Suggestions? BTW - end points, centers and everything else is set nuts on 1000-1500-2000.
@@gregoryhurst5982 Props off first for safety. Then I thought the flight controller might be fighting so I put the props on..... Same result. Also noticed that when I advance the throttle, the motors would spin up then decrease by themselves.
I have upgraded my Emax BUZZ to BetaFight 4.2.6 and updated BLHeli 32.7 and when I enable Bidirectional DShot the Quad will not arm. The error from BetaFlight is RPMFILTER DSHOT_BBANG. If I turn off the Bidirectional it arms and fly’s fine. Thanks in advance for your help.
Will the cli tell me why on a new build the #3 & 4 motors wont spin in the motors tab? I got these weird FC and esc by some guy named bard well. And there brand new! Lol
Ok JB - third time around watching this one 😁 You set vbat compensation to value = 100 I understand, this is turning it on. I think to myself....hmmmm usually, 0 is off and 1 is on, OR true/false, so... Can you set it to lets say 50%? so that the vbat comp isn"t so "linear" from batt start to batt end? Like, maybe it can function, but not AS SEVERELY...like... still a frisky fresh battery, but not such a saggy battery at the end?? I hope that i'm making sense - would love your reply on this....thank you for another awesome vid bro 😎 Oh damn - one more thing- Your notch filters aren't on - and you explain why - what should they be set to? Same as BF 4.1? Thank you JB 😘
@@JoshuaBardwell So, JB, while taking the time to answer my question about the vbat compensation value, didn't answer my second question asking about the notch filter settings. My first impression: meh, he answered you, probably didn't have time to answer about the notch filter settings. And here is yet another instance of JB's magic. Notch filter settings are unique to your quad's particular noise. I think that I learned that once, when I watched his notch filter vid a while ago. ( th-cam.com/video/iUASxYf-6sg/w-d-xo.html ) LOL thank you JB 😘
Changed to 4.2. Everything is flying great but there is a ton of shaking when accelerating upward. Any tips on what to adjust in the tune to fix that. Originally this quad was on 3.5.7 and didn’t do it until the firmware update.
hey josh i know your busy i have a dji air unit and googles and remote...armattan installed...they pre-install with stick arming can i just change that in betaflight to a switch? and will stick arm still exist if i do ?....Thank you for all your time...
Any idea why my home direction arrow just points forward on bf4.2 It worked on bf4.1 with legacy target great it does return the right direction when gps mode is actived but once I fly away from home direction it turns forward
Josh, I took your advice and set the Dynamic Notch Max HZ to 350 and this made my quad uncontrollable and gave it harsh oscillations and random death rolls. I had flown without issues prior to this on 4.1.7 with the Max HZ at 600 as suggested in an older video of yours. I switched it back to 600 and the quad flew flawlessly once again so I don' t know what was up with that.
@@JoshuaBardwell I tried flashing a new version of 4.2 and setting up RPM filtering and the entire quad from scratch (without importing any CLI diffs) and it still gave me the same oscillation issues. I noticed the motors were getting super hot too. I switched back to 4.1.7 and my old CLI diff and the quad flew smoothly again and the motors were cool. I'm not sure whats going on.
Hello Joshua .. perfect as usual. Just one thing ? As my FC is a F4 . PID Loops 4 Khz and ESC D Shot 300. When I check Tasks in cli : GYRO 8000 filter and PID 4000 .. did I l miss something ? is it a problem ? thank you for your priceless knowledge. Regards
@@JoshuaBardwell Thank you for your answer. Assuming I can't change the Gyro from 8000 as you say in the video ; your tuning shows FILTER and PID at 8000 in the cli screen with "Task" command , as mine say's 4000 , this was my concern , am I wrong ?
Thank you Joshua, great tutorials on BF 4.2, I'm making the change now. What green do you use in the logo? I've tried all combinations and BF says size is fine but it won't accept the colours.
Hey I could use a little help, I've ordered an iflight dc3 dji bnf, its my first quad and I'm going to need to flash it to 4.1 or higher to be able to connect my dji remote. I was planning on just saving the settings typing 'dif' and then repasting them in after updating because I'm new to the hobby id don't want to get too overwhelmed in settings too quickly, should I stick to the 4.1 or fully upgrade to the 4.2 and adjust the settings you mentioned? Any help would be kindly appreciated. Many thanks.
4.2 is not released yet. If it's released then I would goto it. Don't paste old settings into 4.1 or 4.2. There are some parts that are ok to paste. Other parts will mess up the config.
@@JoshuaBardwell thanks Joshua, do you have a video on the settings I would need to configure for 4.1? Many thanks man. Big fan! Appreciate what you do.
Warning: If you use your own DJI Remote Controller, you need to update betaflight to 10.6.0 to set up and bind your DJI remote controller. Model 1 setup: Reveiver tap -----> Choose 'Spektrum / Graupner / JR (TAER1234) ' Model 2 setup: Reveiver tap -----> Choose ' Frsky / Futaba / Hitec (AETR1234)' Will i need to flash the firmware to do this Joshua? Or just update the configurator and leave existing firmware in?
What about your APD escs on your Beastclass? Got them on a beast/Xclass but I dont know anything about the APD that allow for bi-directional Dshot but the APD are smooth as hell on 4.1.
I watched your films but missed how you connect a fresh build to Betaflight. Is there a cable connected, wireless, I am at a loss on how it is done. Thanks.
@@JoshuaBardwell Thanks! I found a cable that fits. As soon as my battery connector converter comes in, I will do the Betaflight. My battery connector and drone connector have differ ends but found a connector that will allow the two to work. Thanks for that pointer. Looking forward to flying it soon.
Hi Joshua, Chilean Flyer here. Big Fan! Quick question. what is an acceptable amount of error on the motors tab using rpm filtering? plugged in it's at zero but when I pump the throttle the error starts to rise a bit and on engine one I get into the red and sometimes engine 4. is that normal or should it stay at Zero the whole time?
@@JoshuaBardwell thanks! gonna tak her easy and fly around. it does go over 1 % (red) I assume I have a bad motor cuz I just changed the ESC for that motor. Would less filtering ( I ve space for one more click to the right) free up some processing power and correct the issue. Im running a beat up matek-CTR with GPS, Baro and smart buzzer. LOOP 8 and 4
Did anyone try to setup bidirectional dshot for Zeez f7? I tried on mine, but when I select 8k/8k motors get some minor errors 0.1 - 0.8 and I'm wondering is that ok? Since it's f7 flight controller...
So I was wanting to flash the OEM firmware on an Emax quad. They say I must use link to dl the BF configurator from when the quad was made. While installing it BF telling me I'm supposed to use latest ver of BF which I had but now this older ver is replacing it. I'm trying to learn this stuff. Why isn't BF backwards compatible with itself? This mean everytime I have to use a previous BF version, my current one will be deleted and replaced? This is nuts!
Betaflight absolutely is backwards compatible with itself. You can use the latest configurator on firmware all the way back to approximately 3.2 or 3.0. Basically forever.
Which wires do it put together for the lumineir lux f7 30x30 to the 30x30 lumineir blheli 32 50 amp esc 6s ?more wires on the flightcontroler then the esc
TLDW:
1. Bidirectionnal D-shot and RPM Filters (4kHz PID loop for f411, verify tasks in CLI for excessive CPU usage)
2. set ff_interpolate_sp (AVERAGED_4 cinewhoop, ON race)
3. set vbat_sag_compensation = 100 && set vbat_pid_gain = OFF (be sure to calibrate the battery measurements)
4. Dynamic notch filter (width percent =0, notch Q = 250, notch Min Hz = 70, notch Max Hz = 350)
5. Set rates with new method (follow link to video)
Thank you, Professor Bardwell!
You have set thousands of people free to fly.
Cheers!
Thank you Joshua; after these adjustments that you indicate, my drone has improved a lot.
Thank you so much for this video. I have my quad with blheli S flying great, thanks to your hard work. I paid the $5.95 and got the esc's licenced. Flashed the firmware, and telemetry. Now my quad chimes some star wars theme music on startup, and flies better than ever with your recommended set up. Love ya Joshua, thanks again.
What fc?
JESC and esc music? how?
4.2 feels awesome. Two quads on it with JESC ESCs and they fly great on stock PIDs
I just flashed mine. Do I have to make these changes or should I test fly first??
@@mach389 there is no secret sauce. Just tune accordingly.
Beezer Media thanks much appreciated
I just installed JESC firmware and did the interpolate_3 thing and I don't notice a difference at all. Is there really a difference?
Thanks Joshua for another super video! I really appreciate (as a German) your clear and simple enough English.
My Comment: On a MAMBA DJI F722 MINI MK2 I've got too many errors with bidirectional DSHOT 600 and 8k/8k. Better and good enough DHOT 300 and 8k/4k.
Hey Bud, Thank you for all your vids. I appreciate it. Peace
You are Joshua Bardwell, and I learned something today!
Thanks for driving into this. Looking forward to playing with 4.2.
I like 'you are gonna learn something today' :)
Thanks for the 350 equiv on low. Was scratchin my head on that one going from 4.1.

Great update on the other filter changes after the RPM setup for bf 4.2.
Looking forward to trying actual rates to work on my rates. Thanks Joshua
I gotta give you props brother. I try to watch some other FPV creators to answer my most burning questions but no one satisfies like JB 😂😎 👏
RPM filtering is basically magic. It takes hot motors, and makes them cool, for no reason and no tradeoff at all.
Seems like a full loop feedback using the gyroscope as a means of full control of the motor current/commutation strength and thus controlling the vibrations/phase between the 4 rotors to also minimize said vibrations. Not surprising the motors run cooler and thus more efficient.

Me either. Emuflight flight has treated me way better.
Great video thank u jb
Am i the only one that wants to see features removed?
Shits like IT, never stop learning.
It’s a frikkin rabbit hole!
They should make different tabs: standard, advanced, expert
And make a drop down with presets to start from
8:19 so is it 70, 60 or 80?
90
Just watched the rpm filtering video and it’s 90.
Almost did the intro as the outro lol thanks for the great content.

So what is the interpolate = before you set it to 1 2 or 3? I set it to 3 and now it just randomly jerks in steady straight flight.
would u have a setup tuning guide for 4.2 for those who don't or can't turn on the Bidirectional Dshot slider ?
Something bazaar on mine. I have everything set in Betaflight and all seems to work fine including running motors manually with the master slider. However, when I unplug from Betaflight and bring the quad alive with the radio, hitting the arm switch; the motors speed up well over idle and I get a vibration in the whole quad. I don't have angle mode or level mode set up so I'm not sure whats going on. Suggestions? BTW - end points, centers and everything else is set nuts on 1000-1500-2000.
Without props on? That's not a surprise...quads aren't meant to be armed with props off.
@@gregoryhurst5982 Props off first for safety. Then I thought the flight controller might be fighting so I put the props on..... Same result. Also noticed that when I advance the throttle, the motors would spin up then decrease by themselves.
I have upgraded my Emax BUZZ to BetaFight 4.2.6 and updated BLHeli 32.7 and when I enable Bidirectional DShot the Quad will not arm. The error from BetaFlight is RPMFILTER DSHOT_BBANG. If I turn off the Bidirectional it arms and fly’s fine. Thanks in advance for your help.
Will the cli tell me why on a new build the #3 & 4 motors wont spin in the motors tab? I got these weird FC and esc by some guy named bard well. And there brand new! Lol
Ok JB - third time around watching this one 😁
You set vbat compensation to value = 100
I understand, this is turning it on. I think to myself....hmmmm usually, 0 is off and 1 is on, OR true/false, so...
Can you set it to lets say 50%? so that the vbat comp isn"t so "linear" from batt start to batt end? Like, maybe it can function, but not AS SEVERELY...like... still a frisky fresh battery, but not such a saggy battery at the end??
I hope that i'm making sense - would love your reply on this....thank you for another awesome vid bro 😎
Oh damn - one more thing-
Your notch filters aren't on - and you explain why - what should they be set to? Same as BF 4.1? Thank you JB 😘
Yes, you can set it to less than 100%.
@@JoshuaBardwell Thanks for taking the time to respond JB.
@@JoshuaBardwell So, JB, while taking the time to answer my question about the vbat compensation value, didn't answer my second question asking about the notch filter settings.
My first impression: meh, he answered you, probably didn't have time to answer about the notch filter settings.
And here is yet another instance of JB's magic.
Notch filter settings are unique to your quad's particular noise. I think that I learned that once, when I watched his notch filter vid a while ago. ( th-cam.com/video/iUASxYf-6sg/w-d-xo.html )
LOL thank you JB 😘
You generally shouldn't be using static notches if you are using RPM filters. That's why mine aren't on.
@@JoshuaBardwell (bends the knee) 😁
Changed to 4.2. Everything is flying great but there is a ton of shaking when accelerating upward. Any tips on what to adjust in the tune to fix that. Originally this quad was on 3.5.7 and didn’t do it until the firmware update.
hey josh i know your busy i have a dji air unit and googles and remote...armattan installed...they pre-install with stick arming can i just change that in betaflight to a switch? and will stick arm still exist if i do ?....Thank you for all your time...
Any idea why my home direction arrow just points forward on bf4.2 It worked on bf4.1 with legacy target great it does return the right direction when gps mode is actived but once I fly away from home direction it turns forward
I saw a cleanfligh update the other day...
Hi!, i have a question, if i have Gyro 8000, filter 2000, PID 2000; this means i need to put Gyro 8Khz and Pid loop freq 2khz?
Josh, I took your advice and set the Dynamic Notch Max HZ to 350 and this made my quad uncontrollable and gave it harsh oscillations and random death rolls. I had flown without issues prior to this on 4.1.7 with the Max HZ at 600 as suggested in an older video of yours. I switched it back to 600 and the quad flew flawlessly once again so I don' t know what was up with that.
I don't think you had RPM filtering working. You only set max to 350 if you have RPM filtering enabled.
@@JoshuaBardwell I did have rpm filtering on? I'll check it out
@@JoshuaBardwell Yeah I had bidirectional dshot enabled, Gyro RPM Filter Harmonics Number set to 1 and Gyro RPM Filter Min Freq to 100
@@JoshuaBardwell I tried flashing a new version of 4.2 and setting up RPM filtering and the entire quad from scratch (without importing any CLI diffs) and it still gave me the same oscillation issues. I noticed the motors were getting super hot too. I switched back to 4.1.7 and my old CLI diff and the quad flew smoothly again and the motors were cool. I'm not sure whats going on.
Are you pasting in parts of the old config to 4.2? If you paste in PID, filter, etc stuff from 4.1 to 4.2 it can cause problems like this.
Hello Joshua .. perfect as usual. Just one thing ? As my FC is a F4 . PID Loops 4 Khz and ESC D Shot 300. When I check Tasks in cli : GYRO 8000 filter and PID 4000 .. did I l miss something ? is it a problem ? thank you for your priceless knowledge. Regards
No that's correct. The gyro is running at 8k which is its native rate and cannot be changed in 4.2.
@@JoshuaBardwell Thank you for your answer.
Assuming I can't change the Gyro from 8000 as you say in the video ;
your tuning shows FILTER and PID at 8000 in the cli screen with "Task" command , as mine say's 4000 , this was my concern , am I wrong ?
If you have an F4 then you should have 8k/4k most likely. Definitely if you are using rpm filtering, which you should be using.
@@JoshuaBardwell Thank you !
Joshua turned in to Tom Nook at the end.
are the defaults safe to start with on defaults? i have a 10" setup, the iFlight XL10, 2814 xing motors
Can you please do a video for a 2s whoop setup ?
What would you set the notch max filter for a 6 inch and a 3 inch?
Thank you Joshua, great tutorials on BF 4.2, I'm making the change now. What green do you use in the logo? I've tried all combinations and BF says size is fine but it won't accept the colours.

Hey I could use a little help, I've ordered an iflight dc3 dji bnf, its my first quad and I'm going to need to flash it to 4.1 or higher to be able to connect my dji remote. I was planning on just saving the settings typing 'dif' and then repasting them in after updating because I'm new to the hobby id don't want to get too overwhelmed in settings too quickly, should I stick to the 4.1 or fully upgrade to the 4.2 and adjust the settings you mentioned? Any help would be kindly appreciated. Many thanks.
4.2 is not released yet. If it's released then I would goto it.
Don't paste old settings into 4.1 or 4.2. There are some parts that are ok to paste. Other parts will mess up the config.
@@JoshuaBardwell thanks Joshua, do you have a video on the settings I would need to configure for 4.1? Many thanks man. Big fan! Appreciate what you do.
Warning:
If you use your own DJI Remote Controller, you need to update betaflight to 10.6.0 to set up and bind your DJI remote controller.
Model 1 setup: Reveiver tap -----> Choose 'Spektrum / Graupner / JR (TAER1234) '
Model 2 setup: Reveiver tap -----> Choose ' Frsky / Futaba / Hitec (AETR1234)'
Will i need to flash the firmware to do this Joshua? Or just update the configurator and leave existing firmware in?
Is it possible that Anti Gravity is not available on mac? I cant find it in the settings.
First time I put 4.1 on any flight controller and now I have Hot motors. What is a quick fix?
Watching this for the third time
What about your APD escs on your Beastclass? Got them on a beast/Xclass but I dont know anything about the APD that allow for bi-directional Dshot but the APD are smooth as hell on 4.1.
No support at this time.
I watched your films but missed how you connect a fresh build to Betaflight. Is there a cable connected, wireless, I am at a loss on how it is done. Thanks.
You plug a USB cable into the flight controller.
@@JoshuaBardwell I see that open spot. I’ll check on the right connector for that. I may have a newer cable that fits that smaller connector.
Thanks!
@@JoshuaBardwell Thanks! I found a cable that fits. As soon as my battery connector converter comes in, I will do the Betaflight. My battery connector and drone connector have differ ends but found a connector that will allow the two to work. Thanks for that pointer. Looking forward to flying it soon.
Hi Joshua, Chilean Flyer here. Big Fan! Quick question. what is an acceptable amount of error on the motors tab using rpm filtering? plugged in it's at zero but when I pump the throttle the error starts to rise a bit and on engine one I get into the red and sometimes engine 4. is that normal or should it stay at Zero the whole time?
Under 1% is acceptable but 0% is typical.
@@JoshuaBardwell thanks! gonna tak her easy and fly around. it does go over 1 % (red) I assume I have a bad motor cuz I just changed the ESC for that motor. Would less filtering ( I ve space for one more click to the right) free up some processing power and correct the issue. Im running a beat up matek-CTR with GPS, Baro and smart buzzer. LOOP 8 and 4
could you try fall out of love by illenium and annika wells for a freestyle song?
If this wind ever dies down, I want to fly to one of his other songs.

Still running 3.2 don't need to change anything spend more time flying and less time flashing
it’s all about feature choice, honestly I love upgrading but it’s also not always the best to do if you have a GREAT tune
Did anyone try to setup bidirectional dshot for Zeez f7? I tried on mine, but when I select 8k/8k motors get some minor errors 0.1 - 0.8 and I'm wondering is that ok? Since it's f7 flight controller...
So I was wanting to flash the OEM firmware on an Emax quad. They say I must use link to dl the BF configurator from when the quad was made. While installing it BF telling me I'm supposed to use latest ver of BF which I had but now this older ver is replacing it. I'm trying to learn this stuff. Why isn't BF backwards compatible with itself? This mean everytime I have to use a previous BF version, my current one will be deleted and replaced? This is nuts!
Betaflight absolutely is backwards compatible with itself. You can use the latest configurator on firmware all the way back to approximately 3.2 or 3.0. Basically forever.
Which wires do it put together for the lumineir lux f7 30x30 to the 30x30 lumineir blheli 32 50 amp esc 6s ?more wires on the flightcontroler then the esc
