Nice! Can't wait to see the 4500kv on 3s.

[@blackmennewstyle]

You are a life saver lol I was thinking about getting these motors and hopefully you made some thrust tests with the 6000KV version and i can say it is exactly what i need :D Hope you are doing well! Have a great weekend and keep on flying!

[@EngineerX]

ABMNS PRODUCTION seems the 6000kv are the ones people use most. You can use 2S or 3S. I'm still trying to begin building my 3" microbeast with these. Thanks and happy wishes for the holidays for you and your family.

[@blackmennewstyle]

EngineerX I will give it a try with 2" build for now. It should be a micro rocket lol I imagine people love the 6000KV since you can use 3S, the higher KV version you have to stick with 2S and the lower version is maybe way too efficient friendly but might be consired if you just want more flight time. Happy holidays to you and all your family as well! Take care my friend :)

[@Zeraan1337]

Thanks for making videos that show actual stats! Much more useful than a bunch of people talking about 'feelings'

[@EngineerX]

😁 Thanks for watching and glad to hear you find data useful!

[@digranni128]

Show de bola, se eu tivesse visto o vídeo antes, não teria comprado o motor e o esc errado 😂🙆

[@ganon420]

Nice test. Pretty impressive motor. I have the emax 1104 motors right now and when they die these are on my shopping list.

[@EngineerX]

These will be the best replacement for sure!

[@ganon420]

EngineerX Do you think the emax 6a esc would handle these motors on 3s?

[@EngineerX]

I'd say up to Prop# 8 (except 2840x3) a 6A ESC would be barely OK, I'd would prefer a 12A however. 6A would be too risky, these motors can pull a good amount of Amps so better to have some headroom

[@fiveangle]

How are those 50g thrust tests getting crazy efficiency numbers even possible ? 13.1g/W on a 2.5" 4-blade prop nearly defies the laws of thermodymanics. I call shenanigans 😝

[@EngineerX]

LoL ... Shenanigans indeed!! Looks like I overlooked (happens somewhat often) the funny numbers on that 2.5" Prop# 9 as well as on several other props on these tests. The Excel spread sheet I use is supposed to pick the closest values corresponding to the various thrusts numbers on the table. The formulas I use are not the smartest so often times the wrong values are selected due to logged data limitations: Sometimes the spreadsheet will pull Amp numbers that correspond to when motor is being throttled down or when throttle is cut off and ESC is on "active braking" mode, instead of picking when motor is under load or ramping up. I noticed that started happening more on the small motors. So I gotta inspect tables more carefully.... anyway, logged data is on the Excel spreadsheet I provide in every test so you if you had reviewed it you would've seen it's a mistake and correct data is there on the data; I had fixed those errors on the spreadsheet a while back ;)

[@fiveangle]

EngineerX hrmmm. No offense but we look to your tests as the authority with expectation that you had scrubbed the data you were presenting. If you’re saying that we should treat all your data as just a presentation of what a machine spits out and that to have confidence in what you’ve presented we each need to dig into the raw data ourselves, it severely limits the utility and value of the work you do. You’ve been doing this for a very long time so maybe it would make sense to take your work to the next level and begin honing your data analysis formulas so that they *are* the best. Dropping numbers that fall beyond a specified rage outside the standard deviation is simple freshman statistics 101. You provide a very valuable service to the community but they also rely on the results to be accurate. I’m excited to see what steps you consider for the future to ensure we can be as confident in your work as you are. Thanks for all the testing over the years !

[@EngineerX]

You're 100% correct and I appreciate you looking closely at the data. I will keep reminding myself to scrutinize data carefully before releasing it. As usual, careless mistakes like this happen when on a hurry to complete. No excuse however. When I captured the comment on the thrust table the data was wrong and I neglected to re-capture. I'll make a better effort to look at tables closely. Actually, I have caught the same error from the Excel spreadsheets since then, so I've corrected it manually by eliminating the offending ramp-down values. When I said "it happens somewhat often" I was referring to mistakes in the videos. Sometimes I overlook/forget to change the motor name/model on the thrust test runs (green letters) I use previous video editor files so sometimes the previous motor name transfers to new video. Again, no excuse - just gotta review more carefully. Thanks for watching!

[@alexcrowder1673]

Id love to see 4s thrust test on these.

[@leftyfpv8263]

great! i wish they d sent you the 4500kv too. edit lol i commented before the end of the video. looking forward for that 4500kv on 4s and 3inch

[@EngineerX]

Will do ! I'll be testing the 4500KV on 4S soon.

[@imthesonofjorel]

I have been looking for a channel like this forever!! Subscribed ✅ I only have a Kingkong ET 125 right now. With a dead esc. And since I’m replacing that. I figured I could replace the motor as well. I use the gemfan 2540 props. Would this emac 1106 6000kv motor work well for my ET 125?

[@GroundControlRC]

Great testing as always. Who do you think has the best quality and performance on these 1004-1106 motors between Emax and DYS? Thanks much for all your testing.

[@EngineerX]

So far, EMAX, DYS, RotorX (tests coming soon) and SunnySky have very good quality and good performance, though the SSky 1106-6500 makes a lot of power but also needs lots of Amps. I'm sure there are others but those are the ones I've looked at.

[@GroundControlRC]

Thank you much for information.

[@joegreen7253]

Thank you for your videos I always appreciate them can you please do the 75,000 first cuz I bought him and I want to see what's a really good prop for them and thank you again for your videos

[@EngineerX]

Yes, I'll be testing the 7500KV soon. Thanks for watching

[@DavidHanniganJr]

I mean you'd only need additional wire from the motors if you were attempting to make a hyper light 5", or maybe large 4". Or an Extra-Large 3-inch maybe. Otherwise don't you think that'd be plenty wire, even considering 4-in-1 ESC usage? (On normal 1106 builds) Thanks for your reviews though. Very valuable to me in consideration of parts I would be better served to use. Thanks to you I got a set of the Spintech 1106ST 8000kv motors. Either I got too much ESC for them, or they're too much motor for my 90mm frame that I have. Because I'm having heat issues with them. I'm pretty sure that'll go away if I were to get something like a Leader 120, or 117mm frame to put them on.

[@EngineerX]

Yeah, just nitpicking on the wire length on an otherwise outstanding motor. Those SpinTechs run well on 2S, could it be your FC's tune? maybe need to lower PIDs? Also make sure props are not bent. Hope you sort it out. Thanks for watching,

[@DavidHanniganJr]

EngineerX they're rated for 4s right? The Spintechs, I mean.

[@EngineerX]

No no no no no !!! If they survived 4S then they're a heck of some good motors. They're rated for 2S. 8000KV is too high for 4S. 3S would also stress them too much I think but some people may already be trying them on 3S. www.spintechmotors.com/collections/spintech/products/1106st-8000kv-brushless-motor

[@DavidHanniganJr]

Zak Smiley you referring to the Spintechs?

[@DavidHanniganJr]

Sugar Kane Thanks for the advice. As of the last time I was messing with my 90mm, I need it.

[@mikeydeefpv8661]

hi, tnx alot for all the tests! where can i buy the prop you have on the motor at 7:56? kind regards, mike

[@Szper888]

Isn't there a typo - prop 12 3025 tri blade in description (8:47)? For me it looks like GF 3035. EngineerX can you make test of RCX H1304 4000kv and 5000kv to have good comparison with new 1106 motors (like recently tested Emax)?

[@EngineerX]

Correct that should be 3035x3 Yes, I have the H1304-4000/5000KV motors, just need to get some time for testing. Hopefully next week

[@sergeb2643]

What wire size AWG is used in these motors?

[@MrWidhio]

Can you confirm the thrust and current readings for the RX2535bx4, GF2535x3 and KK2840 @ 50 grams? These seem too good to be true. If these are correct, these props are considererably more efficient than most of the other props here at hovering power.

[@EngineerX]

Those are errors in the Excel spreadsheet data. The 0 - 150g ramp-up logged data ended up out of range of the rows that retrieve the data points for 50g thrust. I've revised the Excel spreadsheet so you can download the corrected table from the DropBox link in the video description. Thanks for noticing! and yes, if those had been correct.... we could hover for at least 30 minutes on a 450mAh Lipo ;)

[@gianlucazizzari]

The banggood page says only the 4500kv is 3s lol, I will wait for you to test the 7500kv on 3s to see the numbers for the blade props and then I will probably invest in a set :D, cheers.

[@EngineerX]

I'll run that one next, but that KV i a bit high for 3S- 12.3V on the thrust stand. The power supply I use can only go as low as 12.3V, I may have to start with a LiPo charged to 11.5V and see how motor reacts (how hot it gets)

[@gianlucazizzari]

EngineerX yeah perfect, cheers.

[@FeWolf]

Issue for me is finding a 2 blade prop for them

[@phatfil77]

Wow! So the RX 2535bx4 makes more thrust and with less amps than the KK 2840x3?

[@EngineerX]

Yes, but that's only on the top-end. Unfortunately I can't spare enough testing time to run more extensive data collection, like running a slower full RPM sweep so we can compare each prop at the various RPMs. If you notice, the 2840x3 will make the same thrust that the 2535x4 makes but at lower RPM, so it should perhaps build thrust just a tiny bit sooner. From what I've read people saying is that the 2840xx3 props works pretty good. I need to try it myself at some point, I just haven't been getting enough flying time lately

[@afiqaFaT]

Im a bit confuse for 3s, gemfan 2035 props, will these 6000kv motor would not get overheat? Is low kv or high kv is more suitable for 3s and 2035 props setup? My stock fly egg100 motors just burnt when i push it a bit. Planning on these motors.. but dont know to pick which kv

[@Frogs77]

AFIQ aFaT I'm wondering the same thing. Do I go 6000 or 4500? With 2035's on 3s.

[@EngineerX]

Lots of people run 3S on the 6000KV motors. Just make sure ESC is capable of supporting the loads. 10A ESC's should be the minimum. 6000 for 3S if you want a very fast setup, 4500 if you want longer flights.

[@afiqaFaT]

EngineerX my stock flyegg 100 motors is 7800kv.. rated for 2s.. i pushed it with 3s racing style then burnt the motors huhuu

[@rolandburrows4859]

So if I wanted to turn my flyegg 100mm into a cruiser using the 4500kvs using 12As ESCs and a GF2035s, that would be good? Or is better to use these 6500kvs?

[@afiqaFaT]

Roland Burrows ok now ive installed the 6000kv, with 3s setup.. its run very2 fast and mltor temps were just abit hot that i still can touch with my finger! Nice!!

[@RCinginSC]

I don't know what the deal is but I ordered a set of the 6000kv motors running on 3s and there things get smoking hot. Even on 2s, they get pretty darn warm. I was running 1105 6000kv hglrc motors before and they never got hot. What's the deal with these motors.

[@EngineerX]

Very strange those are overheating on 2S. I've read one other case with GF3040x3 on 3S running hot.

[@im_ricebowl]

Maybe its the filtering from betaflight 3.4 (i heard that version is known to smoke micros) i ran 1103 on 3s on 3.5 and its fine so these motors should be better.

[@villegasdanful]

Nice video, can u do the 4000kv version on 4s?

[@EngineerX]

Yes, I will test on 4S @14.8V

[@ssaxin81]

Ive saw new motors on Mymcmart, H1304, 4000 and 5000 Kv are avaliable. Calculating iron volume vs 1106 it's roughly same volume for both... it will be very interesting to see test result for this motor , the 5000 Kv ver. How can i contact you to donate or send you the motor fpr testing ?

[@EngineerX]

Hey Eddi, thank you so much for your very nice offer. MyRCMArt sent me those 1304's so I have them on hand.... my only problem is available time to run tests. It's been busy at work so not as much free time lately and weekends have been busy as well, but I'll get to testing them as soon as I can. It will be very interesting to see if the taller stator on the 1106 has the advantage. My feeling is that taller stator has a better distribution of copper since from what I've read the copper on the coil top and bottom (end turns) doesn't produce power so taller stator has less copper there than a shorter stator .... we will see (compared to the 1106-4500KV motor - I'll also be testing it soon)

[@koocoo]

will the 6000kv be ok with 3s 500ma 2030 blades to burn through 3-4 batterys at a time without meltdown on a 80g build?

[@EngineerX]

Hard to say - I have not yet flown the 1106's yet, only 1104-7500kv (but on 2S)with GF1940x3 I've gone through 5 LiPos in a row in a session but not on full throttle. Motors were fairly warm but OK. My best guess is they should be OK... but I would check temps after the first LiPo, if you can grab it firmly with index finger (wrap-around) and not get burnt, then should be no problem

[@koocoo]

follow up, i ran the 1106 with gf 2040 on 3s. 20 seconds full throttle pass the motors would burn your finger. not worth it! :) will melt down the motors after 2 full 3s 500mah battts if you are lucky

[@engizmo]

How hot were these motors getting on the gf3025 tests?

[@EngineerX]

engizmo fairly hot. Close to getting uncomfortable for holding firmly with my hands. But that is quite normal for this size and KV. I think they should be OK in flight but I still check temps on first test flight.

[@MatiXbike]

Do you think it can stand 4s ?? with smal props ??

[@EngineerX]

I have read a couple of people trying 4S but I can't recommend it 100% as I have not really tried myself or seen it done. On a super light 2.5" or 3" (3025 prop) it migh be possible but I would be very careful in checking motor temps. I'd say it's quite risky!

[@Nici619]

can you test the motor on 4s with 2" props?

[@EngineerX]

I might run a couple of 2" props on 4S and add them to the 7500KV video, on the thrust stand motors are highly stressed, so risk of burning windings is high

[@Nici619]

EngineerX ah ok. Thx for the answer and the test.

[@peterzingler6221]

Will they fit on babyhawk:D?

[@EngineerX]

Unfortunately I don't have a Babyhawk motor in-hand. We would need to know the mount hole pattern on the BHawk motor. For propellers, these do have the 2 holes that have same spacing as BHawk props.

[@thmls5744]

I maybe found an one hell of a motor to test, the rcINpower 1108 4000kv and 6800kv www.banggood.com/RCINPOWER-G1108-4000KV-6800KV-Brushless-Motor-CW-for-FPV-Racing-p-1205032.html?rmmds=category should be very competitive to the Rcx 1304 I think

[@EngineerX]

Awesome find !!!! I'll have to order that 1108 !!! thanks for the link.

[@yolofpv2936]

Hey Engineer X! I did a thrust test on these 1102 15000KV motors for a brushless whoop here: kzbin.info/www/bejne/npqbdoZ5h9Z6fKM I’m not sure if I did it in the most scientific way possible. Any chance you can do a thrust test on these guys and some of the 07xx series!

[@EngineerX]

I have tested some of the new BrotherHobby 07XX or 08XX- 10000/15000KV (I forget exact size/KV - got data at home) Just have not had time to sort it out. It was quite difficult to set up those tiny motors.

[@yolofpv2936]

EngineerX That’s awesome! I and a bunch of other people on the brushless whoop train would love to see those thrust tests! Keep up the good work!

[@EngineerX]

I'll be working on several new test results data/videos this week. Had not had any time the last 2 weeks :( Hopefully the data is good. Also have some lower KV RacerStar BR1103-8000/1000KV that I tested. Too many motors so little time ;) Thanks for watching. check back in a couple of week, hope to have video up by then.
