Great results!!! Now do it for 5" sized motors and see if it's the same.
Yes... please!
Exactly what I was hoping for..🤞
YES PLEASE PLEASE PLEASE!!!
I'm gonna try these settings on my 5inch today and see how it is
@@joemck1235 watch out for the expectation bias 😉
Finally a science based report on all those parameters. Waiting for bluejay vs blheli. Great work as always.
Thank you! Working on it!
Did you test other motors for response vs timing? I thought I heard it depends on the kV and voltage for peak performance. Would be really interesting to see how it compares for a typical 2207 ~1900kV racing motor on 6s
Just tested 2207, 1800KV on 6s. Identical result.
@@ChrisRosser do you think I could use this for my 6 inch setup with 2408 f80 pro motors?
@@vladimircerovic I think so. Should be plenty strong enough.
@@ChrisRosser Thank you for the info!
9:30
did you do these tests with 16/24-128 with the min of 16 and the max of 128, or did you do 16 as the min, and "by rpm" as the max? I ask because if you did 128 as the max, you are scaling linearly through the throttle which can cause mid throttle oscillations as you cross the resonant frequency with the motor eRPM and pwm rate. If you did the test with 16-byRPM, then you will avoid the resonance crossings, but likely never got over ~40khz pwm because it's just riding above that resonance crossing which never really gets too high. In order to avoid the eRPM/pwm frequency problems, most users are best off choosing something like 36 or 48nas their min, and having 128 as their max. This will scale linearly through the throttle, but will always sit "above" that nasty rpm/pwm resonance crossing.
I did linear for this video but will test byRPM in the next video.
Is it safe in the new version of betaflight in cli we change the motor pwm manually to set dshoot 1200, because motor in betaflight only maximum in dshoot 600.
I have noticed ESC been advertised as 128k versions. But couldn't find any good information about it. Now thanks to your video I know what it's all about👍
Happy to help
This is an amazing evaluation. Some of the results confirm some 'against the grain' things I and others believe, while some completely shock me. What is most clear though is that there is a tenuous relationship between hardware and software. That is to say that that outcomes you would expect from the programming side don't exactly follow suit in real world application. For example 24khz PWM frequency delivering the fastest overall 'in/out' response? 16deg timing is more responsive than the sacred 23deg? Say whaaaaat? That said, I agree with others that I'd love to see this evaluation on a 2207 motor. Something with starkly different stator proportions. Clearly there is some physical x-factor derailing our predictions of how we think things should be. So I think testing more motors with a broad range of physical attributes is the next step, to see if any trend emerges. I'll just also note that I know some very good racers that have always sworn that 24khz PWM feels best. And that 16deg timing feels best. And few who are sold on the idea of 96 and 128khz. So its interesting that when we put these things to scientific scrutiny, these things fall out, even when they're not intuitive. It an important lesson in trusting what feels good over the latest hype and specs. This is such an excellent evaluation. Thank you so much Chris and please give us more!
Can you do this with 2808 1500kv or 2810 1500kv motors? I need higher top speed and longer flight times with a 7". Thanks!
I thought the specs on this esc says 24-128 how did you get it to do 16-128
Love the scientific approach! However this advice conflicts with existing ESC recommendations when it comes to avoiding desyncs. Seems like your settings are closer to the "ideal" setup, but depending on the motor/prop/esc it could cause desyncs?
I think the only setting that would affect that is timing and 16deg is the default and pretty safe in my experience. If you have desyncs with 16deg then increasing timing certainly may help!
From a more pragmatic perspective, going from 16-23° on timing can reduce desyncs, basically as it's reducing the peak torque demand (somewhat indirectly), and along with moving to 48kHz PWM, the overall effect is noticeable as far as D term being slightly 'softer', in that I want more D gain to achieve the same tune with a very locked in setup comparing PtB runs... but that difference is pretty small.
For somebody that spends more time at higher throttle ranges, the higher timing also works out to being preferable, especially since responsiveness isn't my only goal. 31° timing makes more to end power, but isn't terribly robust or efficient, so the 'ideal' answer would be dynamic timing and dynamic PWM, but getting that dialed in is going to vary by deadtime multiplier and motors, which makes that tricky for an ESC MFG to set them perfectly from the factory
Thanks for doing the scientific work for us! Do you consider doing the same for a (AOS-) 3.5" drivetrain (smaller 12P9N motors, 16bit (bluejay/Blheli_s) ESCs)? Could you check how precise the Dshot-RPM values are against the optical sensor?
I'll definitely be doing som e testing with different sized motors. As far as I can tell the result seems consistent across different motor sizes.
All 128kHz ESC should link this video on their page
Just waiting for FOC to come to this hobby.
my t-motor F7 only supports 3.2kHz/3.2KHz should I still use DShot600 as im trying to run a high kv 6s setup?
Dshot300 is probably best for 3.2kHz 👍
@@ChrisRosser thank you! Really love your stuff keep up the great work brother!
please test 2207 motors so we can see if the results are the same :)
I'll cover it in the next video. The results are the same.
12k subs and climbing. Keep up the amazing content.
Thanks, Will do. 12k Woop Woop!
Intanto complimenti per il lavoro che fai. Ho seguito i tuoi parametri nei miei tre quad 5 inch. Ma tutti e tre (2 Speedybee f7 ESC 50a e uno Skystars f7 con ESC 60 A) hanno problemi quando aumento il gas andando a tremare terribilmente. Ho addirittura perso un elica...
Può essere colpa del dinamico idle attivo? Due cose dinamiche che lavorano sul motore possono creare conflitto? O semplicemente ESC e motori non sono di qualità eccelsa?
👍👀🇭🇷
Great information! While you did qualify that this advice was for 2004 motors - you're not concerned that these conclusions are overly broad given that voltage/kv and esc deadtime could all influence these stats? Some ESCs have deadtimes that are like 3 times that of others and entire batches of certain Mamba ESC's have had serious power delivery issues.
Exactly my concern (see my post). Rampup Power can be different on different ESC's. That's already known. Also overpropped motors will benefit from higher rampup power.
I'm not particularly concerned because the timing and ramp-up power recommendation is the default in BLHeli32 anyway so they are very very very well tested settings that most pilots are probably already using. If people have issues on the stock settings then increasing timing and reducing ramp-up power etc. may help.
You're absolutely correct about the deadtime dependency of some of these, particularly braking and PWM relationships. That tends to absolutely explode the hardware and test count requirements pretty badly though...
@@tehllama42 You're 100% correct on that. And the amount of work doing these tests for even a single ESC is pretty immense for a side hustle. And annoyingly with bl32 (unlike _S), you can't even know the deadtime of an esc without possibly consulting a spec sheet but more likely using your own oscilloscope... mostly just the one size fits all approach might need some qualifications for ESC's like, one of the Aikon's for example, that has a super long deadtime where performance drops off a cliff with increased pwm. maybe i'm being silly about a nuisance that affects a very small subset of people though.
@@CesiumSalami Sounds like Chris's latest result is that at least motor size small bumps don't disrupt the findings overall - I do feel like there will be some deadtime dependencies on what cPWM range really makes the most sense, and that it'll be slightly tied to what timing and motor inertia is there. 31° is definitely how to make the most power, but 16° being better at low RPM can fully explain the responsiveness metric in this case. Dynamic-everything promises to be the best of all worlds, but so far 32.8 has been more problematic than those added features and associated benefits can justify to me (and I was cramming 32.6.6 onto quads as early as I could)
what settings would you suggest for timing for a 7" built with 2810 motors? I've got sitting here but currently using 2806.5's need to make new arms that have 19x19 mount or I'd have the 2810's installed. thanks for the video and your help.
Love your work. Especially the timing was indeed a very surprising result. I always just set it to 23deg as everyone suggested... and also did that on my babyhawk II HD from something much lower, thinking it actually improved handling. Now I wonder what I really felt! (but that thing is just not worth the science as I'm just using my AOS5 since I got that, lol)
You should post some footage of your actual tests by the way... I bet this is super interesting to watch!
Haha, just a lot of whirring and noise during the testing. It's driving my partner crazy :P
I'm pretty sure on my 60amp mamba 128K esc its 24-128k i have two f55's aswell havent built anything with them yet. are they 16 to 128k? why the diffference if true?
What would settings be for lets say a 530 KV motor spinning 12 inch propellers
Hi, Just bought a F55 128k esc. What are big difference between f55 vs f55 pro esc?
@Chris Rosser - Very nice review and analysis! Any thoughts on how the number of motor poles will affect these results? Thinking about the motor timing mostly. Am interested in seeing what else can be done to make a light weight build more efficient (for longer duration & range)
Now do the test with a overpropped motor. The result will be quite different. Hope the most guys here take this with a grain of salt. Autotiming for example can lead to desyncs, same goes to 16° timing on bigger motors. Autotiming is also only more efficient on a thruststand at certain throttle values were the motor only sees static load. In a dynamic environment like during flying, autotiming can give you worse results. On my 7" 16° seems to be the most efficient setting, that's interesting result seeing your test. Variable PWM can produce heavy noise on certain throttle positions due to aliasing effects, check out the Blheli32 thread on RCgroups. 48khz fixed PWM can not be recommended on bigger overpropped motors like 2806.5 with 7x4x3, due to massive lack in torque on zero throttle situations. Any fixed pwm value can induce noise, it's better to try different settings on different builds.
Just my 2 cents, hopefully not everyone will just use your recommended settings on every quad he has and wondering why it's suffering from random desyncs.
Absolutely - while I do actually have 7" builds on 48khz and get good results depending on the motor/esc (i actually do run 48khz on a very fat 2507 7" build ... but not the point...!) You do get those occasional builds where someone, for various reasons that linear pwm scaling causes vicious aliasing that catches you not at one but seemingly multiple places and it's a big deal on 7" stuff since you may cruise at single throttle setting for a long time. The "By RPM" variable pwm and 24khz low setting for 7 and 8" or a higher low pwm rate for 5" stuff is really stellar and more reliable across various setups kv's, throttle limits, motor output limits, etc.... I honestly wouldn't waste time with this variable pwm that's not "By RPM" based like is available in AM32 or BL32 32.8.3 - i genuinely think that the linearly scaled variable pwm option is just bad (period) for real world applications. It's outcome is highly variable given the setup and application vs. "By RPM", which really isn't as much.
If you are having desyncs increasing timing can certainly help. I would agree that PWM frequency by RPM is the best and it should give pretty similar results to linear as you will still be at high frequency at high throttle and low frequency at low throttle. The comment on overpropped motors is interesting. I'll be sure to give that a go.
@@ChrisRosser
Thanks for your work. Looking forward to seeing the results.
@@waldemarkraus2855 Retested with byRPM and results are similar to 16-128k 👍 Also tested a 2207 motor on a steeper 5x4.5x3 prop and results are pretty much identical to the 2004 on a 5x3x2.
Hey Chris, Are all these settings ok for a pretty heavy 1507.5 motored 3 inch quad? My squirt built is trying to carry a hero 9 and it struggles in certain situations so I want to make sure I am getting the most out of it.
Yes they should be!
The big difference I noticed when switching to a 128k by rpm ESC was crazy quick air braking. It's pretty damn cool
I ❤ this content & I wholehearted support your work 😊
How about 2806.5 motors 7" - motor timing and Rampup Power settings - if By RPM mode enable 16-128 rpm. Wanna try to put optimal setup for freestyle. Thanks
Try 16deg and 50% rampup for 2806.5 that's what I run. 16-ByRPM is the best I think.
Beautiful set of results! Thanks for this!
My pleasure!
what i dont get, if i just want pure freestyle flightperformance is it better to use fixed? like it was always reccomended or not? my mamba could go from 24-128....thank you so much
I would use 24-byrpm for freestyle
This data is amazing! Thank you Chris. I've found myself coming back to this video to reference the charts.
Glad it was helpful!
You are sure that mamba f55 pro 128k esc have F4 cpu? Their specifications lack of informations. Great video!
Yes you need an F4 to be able to do 16-128k I think.
Finally the video I've been waiting for someone with a thrust stand to make! Thanks.
Glad I could help!
i like this science approach. lets goooo
lets gooooooo!
Excellent video ultra clear, you know what happen to cncdrones page?, is not working
Just a glitch I think. It's working for me now.
I'm try this. I need most efficient. I normally do 48khz on drones. Except some tiny whoops 96khz. But I'm try auto timing vs 23 I use
Chris, you have the timing concept reversed... the number of degrees represents the off or delay time with trap zero crossing. That is why you would see faster response, greater amp draw with a lower number in the blheli32 timing setting. Thank you for your time doing these tests and being an invaluable member of our community ❤
How do you know it has an f4 prosessor?
Like your videos @Chris Rosser , keep it up.
I have been building my own fpv drone based on a mamba F40 128k.
It uses 2004 mamba 1700 kv motors (wide stator). I am going for 5x3x2 props.
The lift the drone has when arming with standard settings (5,5%) is ridiculous. From what I have seen
1.5% idle is the highest I can set it without taking off xD
I hope that what you say is true and there is a possibility after tuning the quad you will have better efficiency. I am getting my 1000 mAh 80c (I had 48 amps output while I will need atleast 80 Amps) batteries soon which will give the quad a final weight of approx. : 400g > thus the lift it has.
I might just post you the maiden flight. However I am still awaiting my protective coating for the ESC & FC might be wise to use since the weather is not great.
and what about running 48khz low by rpm high. ?. Sad you dident do this test since i think this is where most wanna run it at
That'll have pretty poor braking performance compared to 16k-ByRPM which is the best performing setting in my testing.
A longer video with more motors would be nice. Interested in cinelifter motors mainly. like 2812 and 3115
Looking at this and the recent post by Joshua Bardwell about by-rpm, it looks as if with variable pwm one would never really use 128k at all if you’re not at full throttle.
For a 7” cruiser, I’m looking to squeeze efficiency out of it for max flight time. So what to here? Would 128k fixed be detrimental for stability or the right way to go anyway?
It's also great on kiss so I've heard
Man 10% longer flight time on drones I have already doing over 35mins be crazy
Very nice!
Can you also check a 2812 1100kv size motor which is often used for cinelifter.
How does it behave for x8 configurations with bigger motors?
Hi Chris, I have Mamba F50 pro esc. Does it make sense to use variable pwm 16k-48k by rpm, or just use fixed 48k?
I am very curious about motor timing vs efficiency graph. There should also be interesting observation which might further improve flight time.
Very interesting and informative video. I'm running the Tekko32 F4 (32.8.3) on my Ultra(dshot 2400) build. Motor timing 23, I will try 16 as you suggest. And pwm frequency 24 low and by rpm high. Have you tested / can you test high pwn set to "By rpm"? By rpm is suggested by krunked after numerous test flights. Thanks for sharing, learned a lot. 🤓
its about power~ youll get lower power at lower timings.
@@Krunked Motor timing? So you prefer 23 vs 16? Thanks for all you do Krunked.
@@jlarson42 yes. I personally prefer 23. I find it to be a happy medium between power and flight time.
16 and 23 deg for me had almost identical thrust and power. (8deg did have less power than 16). 23deg had worse acceleration and deceleration though so 23deg is a tradeoff.
@@Krunked thanks. 👍🤓
I had a problem with blheli 32.83 and 48khz as my esc where having dsyncs when i dropped the throttle, and i wonder if you want the data for a test and explanation.
Thank you very much for your viedos, and your content
Finally got a drone .. you're a genius
Cheers! Enjoy it.
Thanks for this! Moving it forward again Chris.
You bet!
I have a v2 Zeez 4in1 that uses L4 MCU's and it came locked at 96kHz and it was really unstable at low throttle, quad felt like I was flying in strong winds, but locking it to 48kHz sorted the issue for me.
I've wanted to try the latest Blheli32 test code so I can test out variable PWM settings but there isn't a hex file for the v2 Zeez 4in1, or I'm unable to find it in the list, they only had the Zeez 60a hex file.
Really interesting ! I’m eager to know 2806.5 / 3008 /3107 and similar performance for long / cinematic flights ! Thanks for all the work. You are doing 👍👍💪
Thanks a lot !!!
Have you seen highly efficient IQ-control motors that have integrated ESC's? Why haven't we seen them already? they are available already for years, except their patented underactuated propulsion.
This was brill. Nice one fella. Fancy doing the same thing to a 250x motor?
Wow, good real data for us
This is the stuff,
the answers to the late night ponderings while staring at specs of components.
"there has to be some way to figure it out"
Huge fan of all the AOS frames so far, 5, 5.5, and now 3.5 built.
the T3, and 7 next...
😍
Wasn't there a desynk issue with larger motors with lowering motor timing below defaults?
Great Video!
Which is more efficient? Motor A with higher kV and auto timing or motor B with lower kV, but higher timing, if both produce the same power at 100% throttle?
I think A, but if anyone can test that, you can. Maybe by varying the voltage instead of using different kvs.
Contrats! Keep the good work!
Thanks! Will do!
Hey Chris. Interesting video, lots of knowledge here!.
What bheli settings would you recommend for Shendrones Siccario X8 with 2x Hobbywing 60A ESC, Brotherhobby 2812 1115kv motors running Hqpropos 8x4.5x3 ?
16-128kHz, 16deg, 40% rampup 👍
Was the variable PWM used the linear variability (setting the min and max), or did you set the min and use the 'BY RPM' for max? I'm assuming the linear setting since BY RPM doesn't seem to get up to max in most cases.
What kV were the ECO II 2004 motors, 1600kV?
Also what version of BLHeli_32, 32.8.3?
Thx!
Linear for this testing. I'll be covering by RPM in the next video
Looking forward to the next video!
Thank you! Me too, I'm learning a lot.
Very interesting variable pwm. 24-128.
That sounds as a great update! Using variable pwm means has to be tweak the “thrust linearization” in betaflight too? If yes, how to deal with it? Thanks mate for your great videos! I learn a lot from you!!!
You shouldn't need to change any betaflight settings as far as I am aware.
I am not sure I agree with using a 2004 as a representation for more common 2207 or 2306 size motor.
It was what I had on the stand at the time. I plan to confirm the results on other motor sizes.
@@ChrisRosser I see. Thanks for replying.
Does Chris have a second channel where he tests all these in actual flight footage and time?
Will you do the same tests for bigger motor/prop combos?
Like 6-7-8 inch?
I'll try. Next video will be with 2207 comparing BLHeli32 and Bluejay. It'll be a smorgasboard of data!
Thanks for this easy learning video! I will try some numbers and see what comes around...
thanks again ross great info as normal. to unmanned tech this happy needs companies like you thankyou.
Have you tried blheli 32.9 on this board?
Yes, works great.
@@ChrisRosser sweet. thanks.
Psshh, im waiting for the 256 pwm escs, going for 20% longer flights! just kidding, thanks a ton for this testing. You finding these mamba pro esc's to be robust? $50 for a 55amp esc seems to good to not have downsides.
I compared today a Tekko32 F4 65A and Mamba F65 on the same rig(10" 2812 Motors) and I'm blown away. No additional noise in my gyro traces with the mamba ESC. Surprised by the result since the Mamba should have least filtration due to lower amount of caps.
I have a really unstable quad after I using variable pwm and it after I change back to fixed pwm, problem goes away. Would you have any kind of setup for variable pwm for a 5”.
Try 32.8.3 test code and 16k -> ByRPM 👍
This actually makes me feel quite good about my mostly pragmatism-driven suggestion to run 48k fixed, 23° fixed, 25% Rampup/Startup with low demag on everything, because it does quite well overall. I suspect taller motors, and particularly tests that focus a bit less on that
Yeah, I think it shows that the received wisdom is pretty good. Maybe a small benefit to going to 16deg and 30-40% rampup. And 16k-byRPM on ESCs that can do that. But the benefit is going to be modest (but maybe still worth having).
@@ChrisRosser This reflects really well on the developers, as stock settings are really pretty justifiable across the board, especially for slightly larger stuff on average.
Once BL_32 is truly stable with dynamic PWM and dynamic timing, then there is finally a justification for the price premium on those ESC's in my mind, but as alluded to elsewhere, the deadtime multiplier sensitivity to that is going to need some sorting out as well.
Chris which version of blheli32 are you running for this test. I know it is 32.8 but was it 32.8.x.x?
32.8. I'm not running the testcode yet. But with the AM32 variable PWM it looks very exciting.
What set you apart from others,? T90
Second, please 🙏 do more common set up like 2207/2306 with 5-5.1 inch prop.
Keep up the interesting content and great hard work!
Yep it's down for me as well. I'm sure it's just a glitch. I've messaged Nick.
@@ChrisRosser checkout this video
There is a common issue with the latest 32.8 blheli regarding rpm and noise
Also a new coming feature of ByRpm will gonna be add to the PWM options it seems to be the best options by the dev suggestion
ruclips.net/video/8plcho0gAgw/видео.html
This is such an interesting and absolutely useful research! Thank you for effort, Chris!
Would 16k-128k variable be beneficial for larger 2807+ size motors or nah?
Yes, I think so. There is no reason that these findings shouldn't apply to larger motors.
Perfect timing! Just bought 2 of these esc's to take advantage of the new biamp setting in blheli32. What do you think about setting low pmw freq at 24khz and the high at the biamp option?
I'm going to test the by rpm option to see if its any better!
how did you make sure that your power meter is correctly calibrated dependless current/voltage fluctuation which is different for different pwm freq. if you would connect osciloskop to your power source you will see definitely non constant voltage....
The current sensor on the thrust stand has a low pass filter on it precisely to filter out PWM pulses. It's a vital part of the design exactly as you say 👍
@@ChrisRosser Thanks for explanation, we should remember that any measurement results, without providing measurements tools accuracy and methodology, are useless ;)
I think you may have lost a section of video between 9:50 and 10:05, it cuts from responsiveness vs pwm freq to partway through a conclusion on motor timing.
Yep that should have been trimmed out. Thanks for letting me know. Should be fixed by youtube in a bit.
me : i don't even know what is blhili or dshot ;)
Thanks chris very interesting video.
Would it be possible to run another test where you can verify your results in a more like real flight situation. I'm thinking that you can run the motor and esc for a longer time from a recorded blackboxlog from a real flight. You can scale the motor power to compensate for the static thuststand.
I worry that copying a flight log will lead to very noisy and variable signals. To be able to detect the small changes a consistent test method is really important. For long range cruising where throttle is nearly constant the slow ramp provides good efficiency information. For freestyle the sharp throttle changes give responsiveness which is the most important criteria for that style of flying. With many configurations to test it is good to be able to keep the tests short as well!
Great video Chris. Thanks for the information.
Great timing, I just bought my first blheli32 esc earlier today lol
I hope its a Mamba!
Haven't watched yet but the holybro f4 esc I was running 16-128 variable pwm and was getting fantastic flight times on it. Also was very smooth
Well damn I did not expect motor timing to be so different. Very very surprised here that a lower motor timing gives more response! I would of thought higher timing means higher response. I find ramp up power to only need to be changed if you are running higher kv motors than you should for cell count. I was running 2205 2300kv on 6s with 5 inch props. It was super overpowered but when I lowered ramp up power down to 10-25% it became much easier to tune the quad.
Me too. Shocking right! Timing below 16deg gives slower response though so it deems that 16deg is close to optimal.
The same is true in the world of automobiles, where 16 degrees engine timing seems to be the standard.
Very interesting. Thanks for sharing that knowledge!
Based on the chart at 8:30 24khz seems to be the best choice... lowest time and the acc/dec time seem to be most similar
For responsiveness I would agree (although the results for 16, 24 and 48 are very similar) but efficiency is better with 48K or 24-128k variable PWM so its a tradeoff.
I'm beginning to think that all flight controllers produces the same flight characteristics. I have a 2017 cl4facing flight controller which I flashed with Emuflight. I flew it and it flew really well like my other quads. I'm in the fpv hobby for 2.5 years now and based from what I have experienced with flight controllers, what I am thinking now is that the possible differences between flight controllers are the build quality, number of pads and layout of the pads. Apology if my post is unrelated to your test. Just wanted to share what I think. Because of that Chris, can you provide at least 3 or 4 flight controllers which you think are amazingly built? ... I'll continue watching now :)
The FCs themselves do very little - the ESC's do play a bigger role. The difference really is processing power (F7 is nice, but F405/F411 work), UART convenience (F7 is very nice, F4's are pesky with inversion and especially F411's UART count), and sensor(s) (MPU6000 is ideal as a single unit, but dual ICM is very slightly better). That's really it, the LDO design on the gyro matters probably the most on performance, otherwise it's all about convenience factors (like JST plugs and available pins, plus more BECs than 5V are great).
I'd honestly point towards the Talon F7-HD for 30x30 for the price right now that's unbeatable, 20x20 I still like the HW F7, Talon F7v2, or FoxeerV722 V2mini, but those are all slightly pricy.
Oh got it! That's awesome information my friend! I'll check out the list you shared. Thank you!
@@neilfpv Of those, only the TalonF7-HD is worth hurrying to check out. It's a really solid unit, I'm a fan.
In a lot of ways, anything with an MPU6000 is going to be solid... and F7's are just easier to work, have more usable UARTs, with and let you run 8k/8k/DShot600, which is perfect.
@@tehllama42 why are some saying that running at dshot 1200 or even 2400 will make motors even run smoother? Do you agree with that?
@@neilfpv Because they have no idea what they're talking about, for the most part.
Very interesting findings!

Yep, top of the line. Thanks to Tyto Robotics for that one!
Great stuff ! Finally data not „feal“ 🤮
Please do this for brotherhobby 3115 with Aeronaut 10x7 Power Prop to see if this holds true for bigger setups 🥰
Seconded this motor! Its the extreme opposite end. Start there Chris and work your way to the middle and see what kind of trends develop =)
Hi Chris can you please make a video on battery's 4s vs 6s needs to have exact same motors and props but with kv so that they have exactly the same rpm output.. I would like to see all the benefits each give as with the weight limits being forced on us I think we might need to go backwards from 6s
