Hi Chris, i have a racing frame with 4 brother hobby avenger motor, the pid chart of that quad is horible, the line is not smooth like your video "Betaflight 4.4 Tuning Guide". Do you know the reason?
Wow… Those Mr. Steel motors round out the bottom of all the charts! Remarkable!
Any Ethix motors big or small I've run have been absolute trash
This company offered me a chance to review, but required a ton of weird things if i made a video and i promptly rejected as it seemed super sketchy.
Very surprised anyone agreed to their demands, hope they are actually good.
Also curious that the most commonly used motor isnt on the graphs (headsup 1960kv).
Yeah they are sketchy AF. Just look at Flying Baguette's comment. I would never want anything to do with them, even if it was free
Most commun motor are Tmotor F series . Jon E5
Yep same bs contract and I said no thank you I don’t wanna shill for a company like that.
Mr Rosser already put a disclaimer in the description. No bs contract signed.
They sent me motors still haven't done the review yet gonna do it tomorrow but i didnt sign anything i just said i would give an honest review & opinion, i use high kv motors anyways & i have my brands that i love already ill never personally buy meps motors for anything specifically because they have 0 that i would want i run fast racing motors kv minimum being 2020-kv & 2100-2150kv being my main go to motors. But besides that yea they did have a bunch of wants & i just straight up told them my channel i do it how i wanna do it noone controls me ill never comply with remote i.d. so why would i do anything else that i don't agree with, ill just end up giving these motors away in a contest or something
I just bought wasp majors based on your site having them as the best weight normalised score.
Did they make you sign the contract?
Hahaha, the sent em to me for free. No contract signed. They're not durable enough for bashing, seem lower power than similar motors.
No I didn't.
i realy love the design of the pink motors and they will be in my first kwad soon
Chris , nice review , but at one point I guess you are wrong, they are not unibell, I broke one exactly on a Hidden sealing straight around two pieces
Nice! Like always! Only see your test :)
A manufacturer might submit "Hollywood" motors; or samples selected from a lot --- Caveat Emptor
Are you planning to do a test of motors for 7" quads? It will be great.
Those fluo green ones look so mean. I'll have to get em. Running the tmotor 2203.5 on my AOS LR5 at the moment, I easily get 10+ minutes of flight time running 650mah 6s, these motors seem to be double the size for the stator. Any guess if my LR5 flighttimes would increase or decrease with these? I'm doing light cruising at less than half throttle most of the time.
Hello, Chris! What can you say about motor nuts? How do they affect to quadcopter?
I just started buiu super lightweight cruising drone and need the most efficient motors for it!
Can you test Xnova motors please ?
Hi, Chris. Any ideas about making video about same motor performance, thrust and efficiency comparison between room temp and pre-heated to 60C motor? Also new motor vs motor that has been heated many times and because of that has less strong magnets? Would be really useful for people who like to buy good used motors or use motors for long time.
That would be an interesting insight
What is the efficiency in size 2207 - 2306? What are you speaking about??
Are you purchasing these motors from the mfg, from retail or are they sent to you for free from the mfg?
Why, if you build 100 motors, they will have some type of bell curve distribution for various attributes. When I was sponcered for a decade racing, the team qould always get the top 5% preforming motors. Thanks for sharing.
Greetings, I like the content of your videos and among your videos I am looking for help to know why when I accelerate the motor it works normally but when I lower the revolutions to zero the motor begins to accelerate on its own to the point that I have to disarm the drone because it does not respond. It is my first drone, maybe I configured something in BF incorrectly but I don't know what, although I use an elrs 500 preset from BF. Betafpv elrs superD receiver, FC mamba h743, betafpv 1w module, radiomaster tx16s. Battery 4s. What can I do so that the motors do not accelerate only when I remove the acceleration in the control????
In Chris We Trust!
@chrisrosser any chance you'll look at the flyfish RC sword and flash? they look very interesting.
Can you test the meps king 2808 6s 2408 6s and 2806.5 6s
Mepsking wanted me to review their motors - but their “contract” was sketchy and they wasted my time, so I blasted them on my community tab…
In their contract terms they requested:
- That I provide “unlisted videos and pictures before release” of the review.
- And, an agreement that “Mepsking would own the rights to use the video that I made AND post it first before I do, if necessary.”
Yes you read the quoted part correctly. 😡
These slimy conditions were deal breakers for me and I’ve been turned off off their product line. I have no idea if they have changed their ways as this was just a couple months ago.
It’s good to see someone actually test these motors to see what they’re capable of, so thanks for doing this.
They tried the contract with me too. I told them to send me the motors and I would test them and publish the results, no more no less.
@@ChrisRosser That's great!
@@ChrisRosser Good man! It might be worth making a quick pinned comment mentioning that, or something in the description.
Mepsking has built a questionable reputation with content creators as evident from the comments section...
Hey, do you have some preferred way of private contact? I wanna learn more about the specifics of the contract and the things they requested
@@Vitroid yep you can use the contact form on my website!
has anyone done a good durability test on all these motors, seems like all motors fly well enough for me, i just get sick of replacing them, i want the most durable over all else.... going to be buying a set soon
My tmotor pacers are bulletproof
Please do a review of the Xhelix FPV Garuda SF 2306 Motor. it comes with a NS54 magnet which should in theory perform better than whats on the market right now.
This looks like sponsored content and I'm surprised and disappointed you didn't disclose it as such. You have a good reputation based on objective data-driven analyses. This is a good way to to throw it all away and lose the trust you've built - be careful!
This is NOT sponsored content. They sent me the motors, I tested them and published the results nothing more nothing less. This is an open offer I have for all motor manufacturers. If they send me motors I'll test them and publish the results so we can compare to all other motors tested.
@@ChrisRosser Thank you for clarifying! Good to know. Stating as much at the beginning of the video might be a good idea. It seems to be the norm, and the omissions here plus some of the comment had me questioning.
@@dishwashersafe222 Good suggestion. I've added it to the description and will make sure to mention it in future videos. Overall I think the test results show the motors are Ok but not great overall unless you only care about efficiency.
@@ChrisRosser I care about efficiency the most. I think the general flight times in the hobby are way too short. Running 2203.5 from tmotor on my lr5 at the moment. I'm getting 10mins of flight time on a lipo and I don't miss any power. I'll be flying with a lion pack soon :D
Thanks a bunch for all the testing, Chris! 😊
Looks like the perfect motors for me! 😬
Anyway, stay safe there with your family! 🖖😊
How many different samples did you use in your testing?
They sent two samples of each.
I have the 2207 motors for 6s and they don't do well for freestyle the shaft bends very easy in light crashes the materials are cheap but maybe to cruse around would be okay but that all
Agreed, these are not bando bashing motors (they don't have the power for it) but better for long range cruising.
will you be reviewing motors for 7" for long range efficiency? ?
Tongue in cheek- like your halo in this video
Why is the stout v4 very efficient in the "best 5 inch motorr" video, for example? much more than the 2306 emax for example and instead in this video it becomes 70% efficient, if I look for the table it now has 90%. Why these changes?
Where is Xnova in any of your charts ?
I use flash hobby 2306 1400kv on my planes. Super efficient on 4 / 6s
Ya I spin a 9x4.5 master airscrew prop on 3s with those motors super efficient and they handle it surprisingly well wasn't expecting much with how cheap they can be had.
@@thirtythreeeyes8624 they work fantastic at such a cheap price that I don’t even look for other motors anymore. Flash hobby on everything now lol 😂
@@dronepilot260rc Ya looking at the windings they're neater than a lot of motors at twice the price.
Salute
you should have tested Xnova lite speed and lr2 too🤣
Each motor will have a max efficiency vs torque. This can be calculated from I_0 and kV. Why are you using a fixed power? This will randomly favor motors for which the parameters align by chance closest to their optimum efficiency point.
meps kings and rcinpower motors are good, but also hard to get in europe anyway. both companies are not able to even set up a useful homepage and links to thrust charts with more than 1 prop. :-) ?? have to ask myself, if i break one, how much does it cost to get a replacement. how long do i have to wait and how long are there parts available. these are the reasons i use t-motor and xnova. t-motor has parts for years and xnova is my new brand i test now. some heli pilots use them in competition. in the quad scene they are not so common, maybe not main target. i know, affiliate has to be there, but some day maybe one pilot will make a test with a xnova motor. bought a T2204, which is one of thr lightest in its class. 20gr for the lr 5. should be not too much.
How much did they pay you?
Nothing. I don't do sponsored videos, I just test motors sent to me and put them on the motor leaderboard. As you can see these motors are very efficient but otherwise unremarkable.
@@ChrisRosser Good to know, thanks!
How are you measuring the watts of mechanical power produced for your efficiency calculation? Most motor test data gives efficiency as thrust (g) / electrical-power (W). This seems like a more intuitive and useful measure of efficiency because thrust and power consumed are two values we practically care about, even if the units don't match. Regardless, can you throw the Rcinpower Smoox 2306 motors on the test stand? Their motor test data shows efficiency that is off the charts compared to other motors.
edit: I saw you had the Smoox 2306 included in the best 5" motor video, and their efficiency tested right at average. Could you try reproducing their motor test data and see how far off your results are? The data they show is 50-75% higher than equivalent motors.
Mechanical power is measured by multiplying measured torque by rpm (in rad/s). Electrical power is measured by multiplying RMS voltage and RMS current. Divide one by the other and you get motor efficiency. g/W is a good measure of efficiency but is very prop specific. Motor efficiency is prop independent.
@@ChrisRosser So was the mechanical power measured with the flywheel?
@@theroburrito It's measured using the propeller. By reporting mechanical/electrical power rather than thrust/electrical power you can separate the motor and propeller efficiency. Motor efficiency is mech watts / electrical watts and propller efficiency is then grams of thrust per watt of mech. power. Total efficiency is motor eff. * prop eff. giving grams of thrust per watt of electrical power. I'll cover this in my next video which is planned to be a heap of 3" prop testing.
And one 2207 burned out totally by first testflight
Mepsking blatantly rips off FPV content creators articles and build guides to post them on their website with no credit whatsoever. Don't think we should encourage people to buy from them.
Seriously?! Will check this out, thank you for posting!
Going to that website right now. If true thank u
I fully agree with FlyingBaguette, no doubt. Too many chinese companiese are appearing on the market just to make business, with no respect for the work done by other.
@@DoctorrMetal I've mostly seen them rip off builds from whiffles on rotorbuilds and articles from firstquadcopter, there's also obvious AI generated content that's just awful.
Was thinking about doing an rc car with an fpv can with gyro data threw telemetry and seeing if that esp32 could do simple image stabilization of analog something something..
I just had a 10 min flight on a 1550mAh on a 6" Banggod w/ Xing 2604 1650kv
They still got those crappy plastic wires?
Mine have silicone coated wire
@@ChrisRosser cool then they must have changed them
T-motor.
Lower KV = better efficiency... Congratulations Chris, you have discovered pyhsics.
Is it only me that find some weirdness between sound and lips movement?
is he british..?... idk.. :-) once you see it. it will make you crazy.
Yeh it’s not synced
Def not the normal quality from him.
yea, this is his only video I noticed that, probably happened in final editing
Si di sicuro sono buoni ahahahahahahahahahahahahaahhahaahhahahahahahahahahahahahahahahaahahahahahahhaahah, primo non sono unibell , la campana si divide nella prima riga rossa, sono fatti di cartone, io ci sto lontano .
Mepsking are trash motors. Buddy of mine tested them out in real world conditions. Overheating, build quality was questionable and one of the set he got didn't last a day
They’re made by T-Motor, I’ve had people send me messages saying as much and that items purchased from mepsking have come from T-Motor office
Only Today...Tomorrow its trash.
