I raced rc cars for 21 years, my sponsor would buy and test a pallet of motors and keep the top 10% of the motors for the team drivers and sell the rest. The difference is eye opening. So looking at one sample is not really what's happening when you buy motors. The quad is limited by the least powerful motor. If these motors were sent to you, they often sent the better tested motors. Thanks for sharing.
Me, who is lazy and cheap: "They're all more than good enough. Got it. Running the cheapest of these I can find"
I really would like to see where the budget options come in against these - basically see if my working theory of '95% of the performance at 50% of the price' still holds, in terms of that extreme edge of the diminishing returns power curve.
I'll have to do a budget shootout next 😁
@@ChrisRosser Yes, definitely. Your results are invaluable for the top 2% of pilots who can actually murder batteries in 69s or less... for quite literally everybody else, they'd be better served running cheaper hardware and using the savings to spend more time on the sticks smashing gates. This even means stuff like running cheap 4S motors on cheap 5S packs. Looking at things like the RPM Authority vs. Efficiency, it correlates so well with KV and mass that once you equalize for pack capability at a given AUW mass, these are at most 5% differences in the extreme cases, and only a small percentage of pilots can even repeatably stress their gear like that through actual tracks (I'm among this group, I just can't hold together the consistency to be truly fast in that regard).
@@ChrisRosser If you have the luxury to add the 'llama special' - 2400KV on 5S into the comparison, I'd love to see where that sits, because it's pretty cheap to throw inexpensive and 15% higher capacity 5 cell packs at cheap/used 4S motors, and it's pace that I personally can't keep up with and have to throttle limit down from, and all but the really fast kids would need to as well.
@tehllama42 that's an excellent question, because I'm on your team! 😂
I love the work you do Chris. I really miss "Rcinpower MCK 2207-2100kv" in the comparison.
i was searching for this comment, feel the same👌
Great tests! The one thing that's missing in my opinion are the five33 champion motors and xnova. The champions edition motors are one of the most used if not the most popular racing motor so it would be great to see how they perform too.
Can assume xnova lr 2207 1950kv are pretty much identical to five33 motor as they're made by the same manufacturer.
Thank you for you work! You make the very best frames and tests!
Timing ON POINT for the MultiGP Season Chris! Another great informed and well documented informational video. Thank you!
i really appreciate these tests, its awsome to see someone doing some actual side by side objective Testing and compaison, and not just talking about what "feels" better. I am curious though how each of these would perform after being bounced off ground a few times.
I can't express how much I appreciate these tests. Do motors for micros/tinywhoops next! There's so little information about those besides anecdotal evidence!
Thanks for the vids, love em!
I'm pretty sure that the exact size of F40 Pro V stator is 23x6.8 which means it was 0.8mm higher than previous model. That should explain some of the torque difference between F40 and F60 Pro V.
Sir ,,, please make a video about top 5 best battery for fpv racing ....😥😥
Your testing procedures are awesome these days! I'd love to argue and poke holes for the sake of it, but I can't. GREAT WORK!
Thanks Chris! Amazing tests. Waiting for I gain tune tutorial - will be very helpful as next step of your PID setup vlog.
Hello Chris, my name is Chris as well. I have been watching a llot of your testing and comparison videos they are very helpful and have a lot of great information that is not normally so readily available to the normal audience member. Thank you for taking the time and heling everyone
Exactly what I've waited for, perfectly in time👌
Great info 😊
Great piece of work. Nice to see someone applying some scientific method to the RC hobbies! I am just starting to play with drones and fpv and your work is extremely helpful! Been playing with model planes since 1956.
I have the Wasp Major 1860 kv on my freestyle build, it goes like a bat out of hell. On my "racing inspired" freestyle build I will most probably use the GTS v3 2107 Plus. Lower weight for the quad and plenty of go is a good recipe 🙂
Love the work you put into this for us all!! Any chance you can get a few brother hobby motors in your next batch!?
awesome results Chris! thanks for this. Quick Q, have you analyzed the negative torque differences assocaited with braking? It came to me that the flipside of those torque curves when slowing also would reveal some interesting differences. I've been doing some testing and noticed a general trend of faster peak motor braking than motor acceleration. be interesting to see how this pans out across motors, given how braking plays a key role in propwash, theoretically
Fantastic testing, Chris! Thanks a bunch! 😃 Really interesting results indeed! I would love if you tested cheap a** motors as well... Just out of curiosity. 😬 Anyway, stay safe there with your family! 🖖😊
Great effort Chris! 👍🏻 Cool stuff! Always curious to see others opinions on motors, as it’s something close to my heart. I fly high KV for racing, and it IS true, thrust is less linear, but honestly this is not critical and doesn’t matter all that much in reality. BUT, having said that 😜 I am weird, and DO straighten the throttle/thrust curve in radio, I fly with a 5% hover, with the rest of the throttle = thrust. Calculating with AUW obviously, and I do this to have more throttle resolution and consistency. OCD and unnecessary, but this is fun for me 😜 I do a specific sequence for the thrust test with the prop and motor I am using… and I made an application that converts my thrust test numbers to throttle curve numbers that I put in my transmitter… every prop+motor combo has its own model obviously… wish Betaflight and such would have throttle curve tuning sometimes, and not just stupid expo poop, but that would be useful only to a handful of people like me. 😜 Importantly, when I do thrust testing I employ current limiting as we fly with batteries and not lab power supplies, even so, results are different in thrust tests -to- air-tunnel -to- real world… soooo, take me with a grain of salt, as with everything. 😜 Professionally I use thrust testing only for magnet and sometimes copper weight/winding optimizations. The test pilots is what really matters, and trumps all, for me… others that I work with disagree 😜 We have “high numbers” motors for the people that buy by marketing and also motors that professionals buy. In addition to the dozen other designs… in the end, it doesn’t matter all that much, people generally employ motors by: appearance, whatever their sponsor gives them, KV, or durability if you are bando bashing. It’s as good as a method as any 😜 Thank you for another perspective Mr.Rosser
Love these motor comparisons, could you use a mouse pointer or highlighter when you're talking about a specific motor so it's easy to see what line in the graph you're talking about without having to pause? Keep up the good work.
I really like the scientific test approach. Thank you very much!
Thank you!
Always looking for the quickest motors.i teach children introuble fpv.and good friend gal kremmer and various company's donated many powerfully motors.we do a monthly build with the kids who each month try build a faster micro than the last.what do you reacon the quickest for pure power.3 to 4 inch
good how are you? Would it be a good option to use the AOS 5 O3 frame with black bird 1950kv motors and I also want to use a gopro 8?
Am i able to use a speedybee f405 stack with a build that has a dji air 03 unit in it or will i need to upgrade my stack to a better one
Cris can you test the Rcinpower Bison motor with a bigger bearing. In the datasheet it's quite an efficient motor, I want to see your tests with it. Is bigger bearing a good step or just a fork in motor design that we should not take care nowdays?
Just finished building my AOS UL7. Holybro F7 AIO with individual Holybro 65A ESCs, Blitz 1.6w VTX, Foxeer Cat3 cam, AXIS 3010 1210kv motos. Still need to make the maiden flight.
I would love to know how consistent these results are for multiple samples of the same type of motor. If the kV is off by up to 5%, wouldnt you expect the overall score to vary by about this much aswell? Since the flight performance of a quad is limited by the worst of the 4 motors, having tight manufacturing tolerances is very important, too.
@Chris Rosser! Would you test the grinder V4 motors? I find that when I break my emax ecoII motors it's the windings that go out. I have started putting the good bells from dead emax motors on the grinder v4 stater when I bend a shaft. The windings on the grinder V4 motors use a noticeably larger gauge winding. I love the fatter windings of the grinder v4 (don't know anything about v3). I am sure the grind v4 motors are probably rebranded something but I don't know what. I wish I could just buy new bells. I think the emax bells have tighter tolerances on the grinder motors than the grinder bells. I'm curious how the grinder motors perform, even though performances isn't everything in this case.
Which 5.5" prop do you recommend for AOS?
Purple motors are usually the best.
The F40 Pro V is 2306.8, so not a small motor.
Oh and the F40 didn't get ranked in the final tiers? 🤣
I'm still going to fly the shit out of them. Been all about f40 and f60 and still prefer them I don't care about bench testing ❤️❤️🤟
I had heard these new F40 were taller than previous 2306, thank you for clarifying it. It actually makes them the biggest motors of this test, not ones of the smallest.
Rcinpower is the new king. power and efficiency. i still love T-Motor for normal use cases, i have the 1204, 2004, F90 1300, F60 and they fly super long with minimal amp use. no race setup!
Please Chris ... im a big fan of you and i really want to know about ethix v5 pink motor silk 1750 its not much info about ... and im shore many of use want to know how the pink motor performs ... thanks Chris 🙂
Hi criss, have you ever got to test the rcinpower gts v4 2207 2100kv mck? i belive it's worth testing. I wonder how it comperes to the T-F40 especially when they are supposed to keep cool.
great job! but why are there no x-nova motors in your tests? these are also top-end motors
Rcinpower on top as always x)
Please add the names of items being tested to your video descriptions. Here's why I ask: in your Jan29 video, you mention you'll be testing the RCinPOWER GTS V4 2207 in an upcoming video. So I go to your channel and search for things like V4, GTS, 2207, RCM (... in the video it sounded like "RCM", not "RCin" - I figured it out eventually), and nowhere could I find a specific reference to that motor. So I went to google and searched your channel name and the name of the motor - no luck. So I went back to the Jan 29 video, checked for a pinned comment mentioning the V4 motor - nothing. I then learned how to download and search the entire collection of a video's comments, and searched that for references to the V4, in hopes that someone might point me in the right direction - nothing helpful, just references to "please test the motor". So expanded the search to all of your videos comments for the last year - too many results to go through manually. So I sat and had a think, and remembered that captions are a thing. So I researched and learned how download a youtube video's captions to a text file, and then proceeded to do that for all your videos posted after the Jan 29 video. ... and now I'm here. Honestly, still not sure this video is the direct followup to the Jan 29th video, or just one that includes the motor, but having spent a lot of time and having learned several new skills, I thought I should stop. Pretty please - add the names of items under test to your video descriptions.
@Chris Rosser how did you measure the Torque? Did you calculate the inertia? of each motor or how did you do it?
Watch his previous motor testing video he did a few months ago. There's a flyweight that he was putting on each motor and spinning them up/spinning them down.
I have a set of F60 V 2020kv on a Mark5 built. Looks like I am getting a set of Wasp now.
Yeeees.. The racing motor test! And I love your JWST pics in the empty screen space. Nerd! ;)
Very interesting and informative video. I follow Minchan Kim, he's running RCinPower MCK 2207 2100kv motors with the Gemfan MCK 51466 V2 props. 3.6" pitch. It'd be really interesting to see that combo tested. Happy flying everyone. 😎
I know this is a big ask; but it would be impressive to see some form a durability test in your motor benchmarks. Be it heat generation / thermal runaway point on flywheel testing or full on what point they "smoke" at. Crashing "shouldn't" be a worry for racers; be we all know "don't crash" is a tall order on anyone. A tree / branch strike kilometers out over a forest covered mountain with a cinema based quad can be hella stressful on the flight home (and have burnt in such situations). I guess I'm just curious if there is even much of a variance in such durability. I'd 110% pick a motor based on if I have a better chance of it getting home with a bench prop (I know this is also tune / frame dependent)... do you think there is even much various here to influence buyer decision - and is there a non-destructive testing method?
how about new MCKs motors?
Can you post your esc settings you were using during these tests? Like your other video your lack of clarification on leaves little room for performance nuances.
The most popular motors with everyone I know are the iFlight Xing. I would have loved to have them included in this shootout.
Be sure to include lamination thickness in your deep dive video 🙏 Would be interesting to see if there's an actual benefit to 0.15mm vs 0.20mm or if any motors with thicker laminations somehow manage to put up better numbers.
nice!!
I do agree with the other wasp majors they are great. I personally race an win with the GTSv3 2107 2080 KV on 6s. The efficiency loss isnt as note worthy on a 1300mah pack with a quad weighing in at 250ish plus battery. Current builds are getting lighter and lighter. That will make a difference on efficiency
Why nobody talks about the Xnova Motors? They are pretty good
Great video! Sad not to see the new Xnova motors here as they were used by top pilots last season (flyfive33 champion and classic xnova). In racing also reliability/durability is very important due to constant full-speed smashing, but hard to compare in these kinds of comparisons.
Couldn't agree more! I reached out to Xnova and tried to buy some. I couldn't get any. Availability is important, you can't invest in a motor that you can't get a month or two later.
The pilots I race with will go with durability first. Nevertheless, great info!!
This is good information. However, it would be good to see what the motor to motor variability is within a manufacturer. For example how do we know if that top performing/or underperforming motor wasn't an outlier. It would be all for naught if one were to purchase a set of four motors hoping they're all the same only to find that the manufacturers variability is too high to make this all meaningful.
Can we get a similar video comparing 7” motors
Awesome work! We need this for tinywhoop motors too! Who is also of this opinion?
Are you planning to do a test of motors for 7" quads? It will be great.
I am also very interested in this and would like Chris to test it😁
Put the wasp major on my new 5 inch and it’s almost to much for me so definitely worth the top spot lmao.
I have nice idea to made super coils,i wana share it with you
I hate RCINPower! The bell is very soft! I bought replacements for the broken ones but I didn't learn, the new ones got bad dents again in a simple crash 😪
Don’t buy uni-bells. They are all like that. 0.2mm aluminum will do that. 😜 I hate this too 😜 it’s a pain in my butt. Steel ring is always awesome for bashing. 👍🏻
@@lemonsquareFPV Cool! I love my brotherhobby returner 6. It's more than 3 years old and has experienced so many severe crashes, I've only replaced 1 motor.
Love from Assam,, India 🇮🇳🇮🇳🇮🇳👍👍 May Allah bless you 🤲🤲
I’m looking for motors for my 3 inch 4s light weight build. I’m hopping between 1404, 1407 and 1507. Which one should I go for a good freestyle quad.
A t-mount 1404 would be good for a lightweight ripper, and I enjoy it… but durability wise a 5mm prop mount motor with a 3mm internal shaft is great for bashing 1506, 1507, 1606, 1607, or something… just make sure you don’t get a 2mm internal shaft motor!!! I’m not sure what you have available to you, but the RCinpower GTS-V2 1506 and EMAX RS1606 are amazing 3mm shaft motors, I absolutely love for freestyle bashing. The 1404, 1604 and 1804 builds that I also fly are a much more fragile.
From these I'd get 1404 for light build.
I404 Xing, hands down, the most quiet and most efficient in the 1404 class for a 3" or 4". I have the T-motor F1404 as well, and would say it's best for a 2.5" or 3"
That 2107 rcINpower motor would be great for racing! Light weight with plenty of power!
IMPORTANT NOTICE: there are 2 cheat motors that you didn't include here. It is the GEPRC 2306.5 1350kv and the OLD Emax 2306/2207 1700kv. These motors are WAY WAY more efficient than ALL the motors (even bigger ones) and sadly they are very hard to find now, either anyone makes something close to that so far...
What about the John Deere motor? I heard that's the best hands down. Can't triple stamp a double stamp
try true dc brushless pipe motor, where a long copper pipe is the dc current induction conductor sheet and radial magnet with iron core rod is the magnet source, and either the rod/magnet or the sheet rotate/move, and the core keeps the inward magnetic field inside the core, then wraps out from the ends, yep dc motors are simpler and dont require any ac/commutators, like ac/pulse motors
yes the iron rod magnet routing core is essential, the rod/magnet stack can be long, just like in an ac transformer
dont even talk about blac motors
the iron core will force the dc magnetic field through the iron core, out from the ends
and the radial magnet field is pushed through the copper pipe sheet
if you more than 2 wires, its an ac/pulse (non-dc) motor
Hmmm, bench efficiency tests are less accurate than bench amp draw tests... You can't factor in the flywheel effect of heavier, higher diameter motors... Heavier motors can be more efficient when you're decelerating the motor.
It doesn't make much sense to normalize the score according to the weight of the motors, since those 2 or 3 grams do not make a difference in the total weight of the drone.
Ummm, what? 2-3 grams x 4 adds 8-12 grams to the total weight of the quad.
Comedy. I just decided on your frame next then you post this after I was staring down some fpv cycles on jbs site.
Yea now I'm curious how my xing2 1700s are against those wasp major greys and measured kv.
Who else remember when Brother hobby was the name of the game😂
These kind of scientific tests scratch a huge itch when it comes to parts selection. I hate it when i go on forums and groups and the answers are like "this can work". Indeed it can, but are you sure it s the best?? ;)
Why do you never include Xnova motors in your videos? They are widely regarded to be a very good brand, at least in Europe.
I assume you tested a lot more motors than you show in your score at the end? As almost all of them are getting scores over 100, that would not be possible.
damn, your tests are very precise, but they are all static, motors can behave diffrently with airflow
I have a small fan that blows on the motors during the test to keep them cool.
@@ChrisRosser I mean airflow on the prop. Maybe it doesn't matter but I think that in flight a motor can spin faster because of the air that is like pushing prop
@@rcfan7349 This is true and it does affect the torque-rpm curve of the prop but when motor testing we don't use a prop to measure torque-rpm curves. We use a flywheel. The prop is only used for power and efficiency testing so we can get a complete picture of motor performance with 2 static tests that applies to any prop and any flight condition.
С вами очень интересно.
RCinPower Pay u for make this video Bro?...... ( I just want to know if this test is fair enough....😉) ✌😋
No, not a penny. And their new motor the GTSV4 didn't do as well as the V3 or Wasp... 😬
@@ChrisRosser 😉👍
but you really chose the worst motors to represent T-motor, if you've chosen T-Motor F40 Pro "II" instead of version "V" then they would've easily won here. version "II" was by far the best, after that they kept on adding weight for no performance benefit, version "II" at 32g was the best motor ever made by T-motor (in this category), the only benefit of version "V" is durability but sadly you give no points in that subcategory.
I still run the F40 Pro II when I’m running POPO props… you are right, still an amazing motor! I run all the newest stuff that comes out too, it definitely still holds its own.
T-Motor just got T-Bagged
This is super miss leading. I will say one thing: rcinpower motors are known for very low tolerances and as a result crazy very low durability. They kill new absolutely, but everyone who tried RCinpower for 5" switched over. Something to consider against synthetic tests.
