ORIGINAL: carlnoki who makes the Tacon Big Foot line of motors then?
Hello Carl, We have a very good idea whomakes theTacon motors. An educated guess would suggest the XYH-EMP factory.
-In: http://www.rcuniverse.com/forum/fb.asp?m=11426913 -post #1 of this thread:
I ORIGINALLY made the comment-just below the section on Sunray Technology motors, and XYH motors:
" ... E-FLITE motors aresimilarin specifications and also in "ICequivalent" naming to TACON motors (sold by Hobbypartz.com), Tacon have a different external appearance (which is only cosmetic). Possibly, TACON motorsmight bemade by Chinahimark factory ..."
-It is easy to miss this comment, in a long post.
Tacon motorsare basically LIKE E-Flite motors at a much cheaper price -however they are NOT identical to E-Flite motors.

Tacon motors ARE all identical with Exceed-RC "Monster Power" motors - http://www.exceedrc.com/mopose.html
The specs of all Tacon motors are completely identical with these "Monster Power" motors.
The only difference between them, is a very slightly different shape front housing, and that Tacon are green whilst Monster Power are blue. That is about it ...
It seems very likely indeed thatthese "Monster Power" motors are made by the XYH-EMP factory -they "look" identical to many XYH-EMP motors, and their specs are similar to many XYH-EMP motors.
Because Tacon motors are identical with Monster Power, it therefore seems very probable that Tacon motors will also be made by the XYH factory.


PS: The website for Zhuhai Huamai Electronics and Model or Himark Electronic & Model Co - http://www.chinahimark.com/
-used to work several months ago, but now does not seem to function. Maybe they have taken it off-line, since as an OEMmanufacturer they do not want to beeasily discovered as the maker of E-Flite, Himax,and some LogicRC/ Tahmazo motors ...?

JP "E-PRO" BRUSHLESS MOTORS
-Guess which factory makes these ...? -Even have identical appearance to E-FTorque and Sonic Electric motors ....

29g
E-PRO 2821/34 34T, Kv 1518=Hacker A20-34 S EVO, Kv1500, 32T=FURY SA-20-34S/1500Kv, 34T =Hyperion HP-Z2205-34T, Kv1530

43g

55g
E-PRO 2832/20 20T, Kv 1022=Hacker A20-20 L-EVO, Kv1022, 20T=Torque 20T/1030=Turnigy SK3 2830-1020kv, 20T=Lipolice LP-2213/20T-1080KV

etc etc

And the JP E-Pro ESC's have identical programming to: E-F Airboss; Common-Sense-RC; Sonic Electric; Gens Ace; OK Hobby Infinite; BMI SpitzESC's; Shulman Aviation FURY ESC's ...
So guess which factory makes the ESC's as well ...?

CONFIRMED:
BMI-MODELS SPITZ MOTORSandPRECISION AEROBATICS THRUST MOTORS -both made at Sunray Technology


EMAIL: From: *******@bmi-models.com
" ... Spitz motors and controllers come from the same manufacturer as Hacker.
-We (also) offer Motors / ESC -COMBO as a complete set, …all in the blister ..." Best regards Bart Hetzheim BMI NV/SA

" ... Hacker makes some of their larger motors ..in own factory .., but ..smaller motors are made by the same manufacturer as our motors, -actually PA Thrust Motors are also made by this manufacturer ..."



NOTE: This email shows that both ESC's AND brushless motors are made by Sunray Technology ...
-Up to now, we have only known about Sunray Technology making brushless motors for a great many brands ...
-NOW we can see that Sunray Techproduce ESC's as well -They will be a major manufacturer of these, no doubt ... -Probably for virtually all the same brands that they produce motors for ...

"-The PA Thrust motors appear to be almost identical with BMI-Models "Spitz" motors -look very similar, with just minor differences ... "

"Tram: "Well, we've been really excited about our newest venture with the CSRC Product line.

"SPECS OF PA THRUST MOTORS -almost identical to Hacker / Torque / Z-Hyperion / BMI Spitz / Turnigy SK3 motors ... "

Lots of almost in there, appears to be, built to our spec....
Even the things you are quoting which I copied from this page alone contradict what you are attempting to say
Like lots of people have said before
Put you money where your mouth is and provide some actual numbers from testing these motors, take them apart and check bearing numbers etc.
Anybody can cut and past and try to guess, then claim close enough, looks almost the same etc.
They may be made in the same place but you haven't proven that they are the same motor. Not by a long shot!
LOL some of the KV's of the motors you are comparing are different by about 200rpm! how can that be the same motor, how come the hackers have a much higher amp rating than most of the cheapies you are claiming are the same! Big difference between 200w and 85w if you are claiming they are the same!
The proof is in the numbers provided by independent testing, not cutting and pasting crap from webpages!

WHAT DO THESE EMAILS AND COMMENTS TELL US ...? -in posts #56 and #58

1. They tell us that BMI Spitz motors, E-F Torque and Common-Sense-RC motors are all manufactured at Sunray Technology,along with "purple" Hacker motors.



2. We KNOW that E-F Torque and BMI Spitz motors are identical (internally) with, and have the same specs as: Hacker and Z-Hyperion motors;and Pelikan Foxy, LiPolice, OK Hobby Infinite, Shulman Aviation FURY, Gens Ace, Common-Sense-RC, Apache, Pilotage Nova-Line, Precision Aerobatics Thrust motors, -to name but a few ...
And then, of course, we also have the Turnigy SK3 motors,which we know are identical internally to Hacker, and also in general have almost identical specs as Hacker and all the other brands, across the whole motor range.



3. This then, would seem to show us the "typical brands" of Sunray Technology -or at least some of these brands.



4. The above emails / posts also tell us that Sunray Technology does not only make brushless motors, they also make a whole range of ESC's.
-This has only just now been discovered. It was not generally realised before, that Sunray also made a range of ESC's (apart from by the re-brander companies, that actually get their ESC's made by Sunray Tech..).



5. It had been thought previously, thatESC's like Hacker X-Pro; Hyperion Titan; E-F Airboss; and also Common-Sense-RC; Sonic Electric; Gens Ace; Apache, OK Hobby Infinite ESC's -were probably manufactured by ZTW, because some of them use a jumper program card that seemed similar to the ZTW program card.
See: http://www.rcgroups.com/forums/showp...78&postcount=3
also: http://www.rcgroups.com/forums/showthread.php?t=1333719



6. However, this ESC jumper program card, whilst it is very similar between Common Sense RC; Apache, Gens Ace, Lipolice and OK Hobby Infinitecards -We canappreciatefullynow that this card is actually significantlydifferent from the ZTW jumper program card. And now, we can understand why the card isdifferent (-reason:-it is not made by ZTW-it is actually made by Sunray, for the ESC's which THEY manufacture...).
http://www.rcgroups.com/forums/showp...7&postcount=13



7. Also: If we examine the order of programming parameters for these various ESC's,then we can see that the ESC programming is identical for: E-F Airboss; Common-Sense-RC; Sonic Electric; Gens Ace; OK Hobby Infinite; BMI Spitz standard ESC's; BMI Spitz data log ESC's; Shulman Aviation FURY ESC's; JP E-PRO ESC's; etc



8. In addition, the ESC programming for Hacker X-Pro ESC's, and Hyperion Titan, Apache, Pilotage Nova-Line and LiPolice ESC's is almost identical toE-F Airbossprogramming -they just have a very slightly different order of programming parameters(-and apart from LiPolice, do not have the Restore Factory Default program setting in position 8).



9. The order of programming parameters is COMPLETELY different for a ZTW ESC -and for all the other re-branded ESC's which are made by ZTW (-and they all have identical ZTW programming) -For instance, in ALL ZTW ESC's, program parameter 4 is ALWAYS: Restore Factory Default



10. Very clearly, Hacker X-Pro ESC's, and Hyperion Titan, Apache, E-F Airboss, Common-Sense-RC, Sonic Electric ESC's etc-cannot be made by ZTW.



11. So if it is not ZTW, then which (chinese) factory DOES make all these different brands of ESC's ?



12. It is Sunray Technology, of course.All along it has been Sunray Technology makingthese ESC's, over the last 7 or 8 years -and it never was ZTW ...



13. So: As well as making brushless motors for all of its"typical brands" that Sunray Technology supplies as an OEM manufacturer, Sunray Tech also makes ESC's for almost all of these same brands:
Hacker; Hyperion Titan; Apache; Pilotage Nova-Line; LiPolice; and also E-F Airboss; Common-Sense-RC; Sonic Electric; Gens Ace; OK Hobby Infinite; BMI Spitz standard ESC's; BMI Spitz data log ESC's; Shulman Aviation FURY ESC's; JP E-PRO ESC's; and previously it made ELE-RC "Advance" ESC's (now discontinued) and Watts-Up Hobbies AP 90A ESC (now discontinued);
In addition,Sunray Technoilogy may well make Precision Aerobatics Quantum ESC's, which in many cases look identical to Gens Ace and LiPolice ESC's.



14. It is also highly probable that Sunray Technology make all of the JETI ESC's, since there is a very close relationship betwen Hacker and Jeti. In addition,various other evidence also suggests similarities between Jeti ESC's and many of the "typical" Sunray brand ESC's.




QED - quod erat demonstrandum...-That is enough for now ...

ORIGINAL: siberianhusky Anybody can cut and past and try to guess, then claim close enough, looks almost the same etc.
Well, we DO have direct admissions from: BMI-Models,Common-Sense-RCand also Extreme Flight, that their motors are all made in the Sunray Technology factory. That is something you cannot possibly argue with, siberianhusky.
Also, we now know for certain that PA Thrust motors aremadeat Sunray Tech; And it is very revealing that BMI Spitz motors and PA Thrust both claim to use"High Velocity Forced Cooled Ventilation (HVFCV)" -This doubtless indicates there mustbe great similarity between these motors internally, even if the outside is slightly cosmetically different.
-And it has been realised very widely for a few years now, that Hacker motors are identical (apart from cosmetic appearance) to E-F Torque and to Z-Hyperion motors, and that they are all made together in the same (Sunray) OEM factory. It would seem pure folly,siberianhusky, to attempt to argue against this widely accepted fact.

LOL some of the KV's of the motors you are comparing are different by about 200rpm! how can that be the same motor
siberianhusky: Please point out where the Kv of equivalent Sunray OEM motors (from different Sunray brands), differs by 200 rpm / V. On the contrary, itseems to me that the Kv's matchup extremelywell, within about 20 or 40, and thatis the best that can be expected from Kv. In many cases, the Kv's of equivalent Sunray OEM motorsarealmost identical.
ALSO: Do you really believe the absolute accuracy of each quoted Kv,by each motor brand ...?-It is quite obvious that some of the brands(-like LiPolice, Foxy and Shulman Fury) have anyway simply quoted the Kv given to them by the manufacturer, ratherthan doing any measurement themselves...
And also, it is quiteclear that OK Hobby have usually changed the Kv value by 10, 30 or sometimes >80, from the original Sunray manufacturer value, simply to give the illusion thattheir brandmight be a little different spec fromother identical motorslike e.g. LiPolice or Foxy ...

Also should be realised: That Kv is the "specific no load speed"and is just a theoretical value -true Kv can never be actually measured, because a motor cannot be in a totally zero-load condition, and also internal resistance (Rm) and motor losses prevents true Kv measurement.
Kv is usually only calculated -by making V and I measurements with 2 props, and putting the figures into a program, such as DriveCalc.
Other people actually measure ns -the "real world specific no load speed" -and this does include motor losses. ns is always slightly less than calculated Kv.
Some retailers justmount a small piece of marked plastic on the motor shaft, and take a tacho reading with the motor running at known V, and then calculate Kv =Rpm / V Clearly this will be a very poor and inaccurate Kv, and cannot be regarded as a serious measurement.
So the conclusion is: We cannot really believe the absolute accuracy of any quoted Kv ... The fact that the quoted Kv of some identical motors might vary by 20 or 50 isof no real consequence at all, and is best taken with a pinch of salt...

Default RE: Which chinese factories make various brushless motor brands?



siberianhusky: how come the hackers have a much higher amp rating than most of the cheapies you are claiming are the same! Big difference between 200w and 85w if you are claiming they are the same!
siberianhusky: I am very confused indeed about what you state; Please tell us precisely where you got the figures of 200W and 85W, and for which particular motors.
I quickly looked at a few motors, and obtained the following data (assuming you might think of SK3 as a "cheapie" ):
http://www.hacker-motor-shop.com/e-v...&t=3&c=16&p=16
http://www.aeroshack.co.uk/shop/gbu0...kerMotors.html

Hacker A20-20 L EVO -max 19A, max 200W; Turnigy SK3 2830-1020kv, 20T -max 18A, max 168W
Hacker A30-28 S V2 -max 25A, max 250W; Turnigy SK3 3530-1150kv, 28T -max 24A, max 330W
Hacker A30-12 L V2 -max37A, max 500W; Turnigy SK3 3542-800kv, 12T -max 42A, max 625W,
Hacker A30-10 XL V2 -max 45A, max 600W; Turnigy SK3 3548-840kv, 10T -max 50A, max 750W

As you can see very clearly indeed, there is very little difference between the equivalent same-size Hacker and SK3 motors. In general, the SK3 motors are actually rated for larger current and power, compared to Hacker. So it appears to be completely opposite to what you suggested..

the cheapies you are claiming are the same
Worth noting I am not talking anywhere about so-called "cheapie" motors -we might typically regard EMP XYH -types, standard Turnigy, Emax, Suppo, Mystery, as "cheapie motors".
There is nothing "cheapie" about E-F Torque, Z-Hyperion, LiPolice, Shulman Aviation FURY motors ...
Fact is: All these motors are made in the same large OEM factory, side-by-side with Hacker and all the other brands, and all of them are just re-branded with different external colours andstickers ...

... not cutting and pasting crap from webpages!
So I wonder, siberianhusky: Why are you quoting "200w and 85w" -and where did this info come from ...?

ORIGINAL: siberianhusky
Common-Sense-RC Product line "... these motors ... are built to our specs by by the same manufacturer that produces them for some of the largest companies in the hobby ..."
You picked up on Common-Sense-RC (CSRC) motors, and suggested they might have different specs from other OEM motors produced by the Sunray company, because CSRC state ".. built to our specs ..". I spent a few mins looking at specs of CSRC E-series motors - http://www.commonsenserc.com/page.php?page=ezmatch.html -and managed to get weights /dimensions from 1 or 2 other sites.The table below shows how they match with other Sunray-produced OEM motors:

28mm external diam motors
CSRC E5-M-11, 41g, Kv 900=Hyperion Z2209 32T, 910Kv =SONIC ELECTRIC SE-2809-910, 32T=Pilotage Nova Line DT2209/32-910, 32T

CSRC E5-M-14, 41g, Kv 1200=Hacker A20-26 M EVO, Kv1130=Torque 26T/1135=Turnigy SK3 2826-1130kv, 26T=HYPERION Z2209-26T 1120 KV

CSRC E5-L-8, 56g, Kv 800=LiPolice / Foxy 2213/24T-880KV=Infinite A2213-862, 24T=HYPERION Z2213-24T 850 KV



CSRC E5-L-10, 56g, Kv 1000=Hacker A20-20 L-EVO, Kv1022=Torque 20T/1030=Turnigy SK3 2830-1020kv, 20T=HYPERION Z2213-20T 1025 KV


37mm external diam motors
CSRC E8-S-10, 76g, 1000KV=Torque 2830T/1095, Kv 1095, 30T=APACHE APS30-30T 1070 kV=Pilotage Nova Line DT3007/30, 30T, Kv1050

CSRC E8-S-12, 76g, 1300KV=Turnigy 3530-1340kv, 24T

CSRC E10-12, 111g, Kv 1200 =Turnigy SK3 3536-1200kv, 14T=LiPolice / Foxy3014/14T 1132KV, 111g =HYPERION Z3013-14T 1085 KV

CSRC E25-12, 160g, Kv 1200=Turnigy SK3 3542-1250kv, 8T


As yousee, the CSRC motors match up very well indeed,with the specs of other OEM motors produced by Sunray Tech.
So, although CSRC themselves state that their E-series motors were "built to their own specs"-actually, most of the CSRC motors have specs which are the same as for matching Hacker / Z-Hyperion / Torque / Nova Line / SK3 motors. In other words, most of theCSRC motorsare simply re-branded standard size Sunray motors.


Pics showa CSRCE5,E8andalso a CSRC"E-46"-size motor (i.e. equivalent to a 46 IC engine). Noticehowthe packaging is exactly thesame asfor Hacker /BMISpitzmotors, and for e.g. E-F Airboss ESC's-this seems to be a characteristic and almost diagnosticfeature of a Sunray Tech OEM product.
Also notice how the front housing of CSRC motors is identical to Foxy motors;-see previous post #50

EXCEED-RC BRUSHLESS MOTORS -from Hobbypartz
http://www.hobbypartz.com/exceedrc2.html
-Looked at these,after carlnokiasked aboutthe Hobbypartz TACON motors, in a previous post.These Exceed motors havea most incredible range:

1.Exceed RC Legendmotors
For Light Weight Planes & Small Quads -Theseare all exactly the same as the older Tiger motors(now discontinued)
e.g.http://www.himodel.com/electric/T-Mo...ess_Motor.html
Exceed RC Legend 1304-3400KV T-1304, 8.5g, D16 L11 =T-motor T1304 3400KV
Exceed RC Legend 2008-2000Kv, 31g, D26 L15 =T-motor T2008 2000KV

2. Exceed RC Rocket Motors
Look very nice and well made motors (see pic below);From stator-size2205(33g)all way up to stator 4120(292g)
About 80 motors in the whole range...! -The 3015 range alone,has 12 motors with different Kv's ...!
WONDER WHICH FACTORY MAKES THESE MOTORS ..?(I have no idea -I do not know a factory which makes 12 different 3015 motors..!)

3.Exceed RC Optima Motors
Some of the EDF motors in this range(e.g. Optima EDF Motor 64mm 3800KV) look exactly the same motors as:Turnigy 2810 EDF 3800kv for 55/64mm fanand also E-Flite BL480 Ducted Fan-These Optima and Turnigy EDF and E-Flite DF motors must all be from same manufacturer (seepics)...
http://www.horizonhobby.co.uk/aeroon...flm1550df.html

4.Exceed RC Elite Motors
Inrunner motors for park fyers.Identical to the Exceed Elite motorson Exceed-RC website -http://www.exceedrc.com/eliteseries.html
-Looks like these motorsare made by the Exceed-RC company ...?

5.Exceed RC Helium Motors
Helicopter motors

The Exceed-RC "Monster Power" motors used to be sold by Hobbypartz-now seem to have been discontinued.
However, they are still sold by Exceed-RC - http://www.exceedrc.com/mopose.html
-It has been generally assumed that these motors were made bythe XYH-EMP factory -http://en.xingyaohua.com/html/class/213.html
However, I have just realised that these "Monster Power"motors have IDENTICAL specs to both TACONand E-FLITE motors.
-This might then suggest they are made by the ChinaHimark factory (Himark Electronics) rather than XYH-EMP.

I PRESUMED, SINCE THE MOTORSARE NAMED "EXCEED-RC",THIS SUGGESTEDTHEY ARE MADE BY THE EXCEED-RC COMPANY - http://www.exceedrc.com/ -It now appears thatExceed-RC probablyhave them made by variousOEM companies, and just slap their brand stickeron. After all, we can see that theExceedLegendmotorsare made by Tiger-Motor and not by Exceed. It therefore seemsthatExceed-RCare not manufacturers, but re-branders.


Pics show: Some of the Exceed-RC Rocket motors, and Optima, Turnigy and E-Flite DFmotors which appear identical

ORIGINAL: siberianhusky They may be made in the same place but you haven't proven that they are the same motor.
The proof is in the numbers provided by independent testing
Yes siberianhusky, in some ways I agree with you. I do not think anyone can seriously question that Hacker, Torque, Z-Hyperion motors are made in the same Sunray OEM factory. And it is perfectly obvious that Pelikan Foxy, LiPolice, OK Hobby Infinite, Shulman Aviation FURY, Gens Ace, Common-Sense-RC motors and all the other typical Sunray brands, are also made in the same OEM factory.
But are they all exactly the same motor, as far as internal parts, and performance figures are concerned ..?



So far, we have the evidence of Dr Kiwi (Phil), showing that Torque, Hacker, Hyperion and OK Hobby Infinite motors are identical, and give exactly the same performance figures. Dr Kiwi also commented for Hacker and Torque motors that " ... the bearings and shafts look identical ..."
http://www.rcgroups.com/forums/showthread.php?t=358646
Dr Kiwi also found that Hyperion, OK Hobby Infinite and Turnigy SK3 motors were identical in construction and performance.
http://www.rcgroups.com/forums/showt...1521696&page=4
We also have comments from various other people that the internal parts of Hacker, Turnigy SK3, Gens Ace, and Hyperion motors are identical.



However, as final proof we really need a properly organised examination of the motors and independent tests of their performance figures. That is why I am in the process of constructing a Motor Thrust Test Stand (to take at least 50-size motors), and I am also setting up an Eagle Tree data logger.
All will be revealed, in the next several months ...

G-FORCE MOTORS -from Value Hobby
I very recently noticed a range of motors called "G-Force", sold by Value Hobby. These came up because the G-Force "G25" motor was mentioned as the suggested motor for a pretty-looking 30-size F3A plane called the "Oasis F3a" - http://www.rcuniverse.com/forum/m_11351624/tm.htm



The range of G-Force blue coloured motors is shown here: http://www.valuehobby.com/power-syst...-airplane.html
They range from a small 2204 motor (22g, Kv 1650; 28mm diam; stator size 2204) -up to a largish "G60" motor (360g, Kv 400; 5065 on external dimension -i.e. 50mm diam, 65mm long; likely to have ~4030 / 4035 stator).
The smaller motors are named with respect to stator size and then brushed motor equivalent (e.g. 400, 480). Motors of 100g and above are named with respect to approximate IC power level -e.g. G10, G46 etc.



Question is: Which factory makes G-Force these motors ...? Short answer is -I do not know. Any ideas out there ..?
Let us take the G25 motor as an example -They state it is a "3548" motor (on external dimension) -it has specs 160g, D~35 L~48, is avalable with Kv's of 850 and 1100. Prob has ~2826 / ~3025 stator. They state it is a "Good replacement for E-flite power-25". The pics below show the front and rear housings.



a. First, is it a motor made by the XYH-EMP factory ? - http://en.xingyaohua.com/html/play/427.html (XYH "N-type" motors)
-XYH list 3548 motors, with weight 171g, and Kv's 790, 900, 1100. So the Kv of 1100 and weight about matches up. The G25 Kv of 850 does not.
However, it is clear that XYH also make a ~3548 size motor with a Kv of 850, because there is a "Turnigy 3648 850kv" motor,and this will be made by XYH- http://www.hobbyking.com/hobbyking/s...or_1450kv.html -It is quoted by HKing with weights varying from 131g to 181g ...
-So: Maybe the G25 motor is made by XYH, with just the front and rear housings changed to a different cosmetic shape ...?



b. If we look at the XYH "C-type" motors - http://en.xingyaohua.com/html/play/409.html -then their rear housing has a little similaritywith the rear of the G25 ?(see pics) -so again, maybe the G25 is an XYH motor ...?



c. Also, some "Mystery" motors have been advertised with front housing that looks similarwithG25 motor (see pic) -and Mystery motors are usually made by XYH.



d. Front housing of G25 has some similarity to Topband motor (pic 6 below) -so maybe Topband is manufacturer ? - http://www.topbandmotor.com/en/chi/a...=161&comid=113



e. Certianly, G25 is not same as the E-Flite Power 25 motor -the E-Flitehas weight of 190g, although has Kv 870, and D35 L54



f. Is it an EMax motor ? -There isan Emax BL 2826-this has specs 182g, Kv 850, D40 L48 - http://www.emaxmodel.com/views.asp?hw_id=114-So Kv is same, but Emax motor has diam of 40mm, and does not look anything like G25.AlsoEmax motor accessories look different to G25. So does not appear to be an Emax motor.



g. Also does not appear to be a Suppo;Saite;or a KMS / KBM -type motor ...



So: As I said at the start -It is not clear (at least to me) who makes these G-Force motors.
Maybe it IS the XYH factory -and just front and rear housings of G-Force motors are changed from the standard XYH style ...?



What do you think ...? Any ideas out there, for who might make theseG-Force motors?


Pics show: 1 & 2, front and rear of G25 motor; 3 & 4 show rear of 35-size XYH "C-type" motors; 5 shows front housing of a "Mystery" motor; 6 shows Topband motor.

Default RE: Which chinese factories make various brushless motor brands?



G-FORCE MOTORS (Value Hobby):
Have considered this a little more: I think G-Force motors MAY be made by the XYH-EMP factory.
There are 2 reasons for suggesting this:



1. I have seen that "Mystery" advertise motors with exactly the same Kv's and size as the G-Force G25 i.e. Kv's of 850 and 1100 (see 3 pics below -all are Mystery "3648" motors, size is given on external dimension -same external size as G25 motor),



2. Mystery motors like this are usually made by XYH-EMP -and the green 3648-850 one is without doubt an XYH-EMP motor -the front end housing looks typical ...



3. Another reason is that if we look at G-Force Heli motors - http://www.valuehobby.com/power-syst...nner-heli.html
the "G Force E500-1600KV Heli (500 Class)" heli motor is obviously an XYH-EMP motor (see pic 4)
If a G-Force Heli motor is made by XYH, then the airplane motors are likely to be also made by XYH ...?



4. This exact same 190g 1600 Kv heli motor, is also sold by HobbyKing as the "X500-TW-1600 (Heli)"and used to be called the "HobbyKing 500H Heli Motor 1600kv"
-This very same 190g heli motor is also found on eBay as the "5STAR 1600KV Outrunner".
All of these motors are very obviously made by the XYH-EMP factory ...

Tentative conclusion: G-Force motors may be made by XYH-EMP -with just a small cosmetic change i.e.the front and rear housings changed from the standard XYH-EMP style ...




pics show: 1,2,3, Mystery motors; pic 4 shows G Force E500-1600KV Heli motor (500 Class); pic 5 shows HobbyKing X500-TW-1600 (Heli) motor; pic 6 shows 5STAR 1600KV Outrunner motor; pic 7 shows HobbyKing 500H Heli Motor 1600kv (name now changed ...)

"MYSTERY" MOTORS -have found this new info (well, newto me anyway ...)

http://www.rcgroups.com/forums/showp...76&postcount=7
Dr Kiwi: " ... Mystery is Shenzhen Sudan Yuanda Model Co.,Ltd (Red China)
http://www.777model.com/en/product.asp?cid=172&PageNo=2&keyword=
The KMS brand motors that Hobby People and a few other sell, are by the same manufacturer.
... (..Mystery) D2830-3200 (3200 RPM/Kv) ... is identical to ... KMS (Quantum) 2213-05 ... but KMS doesn't sell the hardware with their motors either, or separately either.
None of these slick dealers in Hong Kong are supplying the motors for planes with connectors, mounting hardware or Prop adapters ..."

The above linkdoes not work; Buthttp://www.777model.com/ does ...
" .. Established in 1995, Shenzhen Industrial ... Sudan Model Department is a high-tech organization specializing in the design, development, manufacturing and distribution of all kinds of R/C model products and optical glass, lenses and binoculars, spotting scope, monocular... "

Airplane motors are shown on: http://www.777model.com/product01.asp?id=43&c1=43
Very large range of motors: From 2204 19g motor, up to 3648 216g 37mm diam motor



Some of them appear to XYH-manufactured motors e.g. Mystery F3648 1700KV http://www.777model.com/product01view.asp?id=2097
THERE ARE SO MANY MYSTERY MOTORS .... !



I suspect many of the "Mystery" motors come from a whole range of different OEM factories. They do not appear to manufacture motors themselves. -The Mystery company just appears to obtain motors from a range of OEM companies, and re-brand them as "Mystery" ...

Some of the "Mystery" motors are also made by SUPPO e.g.The Mystery2212/15 930 kv motor, is obviously a SUPPOA2212 / 15 motor - http://www.suppomodel.com/
also see: http://www.rcuniverse.com/forum/fb.asp?m=11470090

FYI: Mystery "Star" ESC's -use a ZTW program card http://www.777model.com/product01view.asp?id=287
-and therefore are re-branded ZTW ESC's

pics show: KMS Quantum 2213-05 motor; and Mystery D2830-3200; they are indeed the same motor ...
-They both have same weight (58g), same Kv 3200 and same dimensions ...

KMS QUANTUM motors: -ARE THEY THE SAME AS AXI motors ...?
I have now found this information:



http://www.rcuniverse.com/forum/fb.asp?m=10021231 -Sept 2010
cobrajocky: " ... The KMS Quantum 2820/05 was the exact same motor as the AXI Gold 2820/10 (KMS is a manufacturer in China), but apparently Global Hobby has dropped them to carry a really crappy line of their own ... Either way, there are no KMS motors in the US anymore ..."



I do not know how true it is,that KMS Quantum motors are the EXACT SAME motors as AXI ... -I have never looked ...
Certainly, KMS Quantum motors are still available from many outlets in UK (in March 2013) -e.g. http://www.sloughrc.com/default.asp?...:120-010,b:KMS
-even if they might not be available in the USA any more ...

Now: Might KMS Quantum motors REALLY be the same as AXI motors ..?
After all,KMS Quantum motors are usually much less than half the price of a same-size AXI motor e.g. http://www.electricwingman.com/brush...gold-line.aspx



Let us have a look: First, KMS Quantum 2820/05 vs AXI 2820/10 GOLD LINE
http://www.sloughrc.com/default.asp?...=M-KMSQ2820/05
http://www.modelmotors.cz/index.php?...e=10&line=GOLD
Also: http://www.rcgroups.com/forums/showt...7#post19255401



KMS Quantum 2820/05: 142g; Kv 1130; Diam: 35mm Length: 48mm; LiPo: 3-4 cells
=
AXI 2820/10 GOLD LINE: 151g; Kv 1200; Diam: 35mm Length: 48mm; LiPo: 4 cells



-The specs of these 2 motors are certainly close to each other;a small Kv difference is easily within the range of measurement error; small difference in weight may be due to one motor weighed with connectors, the other without ...
***** And the 2 motors do look VERY very similar -indeed almost identical -on pics, see below ... *****
-And even the accessories for AXI and KMS Quantum motors look identical ...

Another comparison:
KMS Quantum 4120/05: 307g; Kv 710; diam: 50mm Length: 55.5mm; LiPo: 3-5 cells
=
AXI 4120/14 GOLD LINE: 320g; Kv 660; diam: 50mm Length: 55.5mm; LiPo: 4-5 cells



-Once again, specs are very close, Kv difference is easily within range of measurement error; one motor may have weight quoted with connectors, the other without connectors, etc ...
**** AND: THE 2 MOTORS DO LOOK ALMOST IDENTICAL (see pics below) ****




SO: WHAT ARE WE SEEING HERE ....?
ARE KMS QUANTUM MOTORS MADE IN THE SAME CHINESE OEM FACTORY AS AXI ??
(-Like the situation with: Hacker and Torque, Z-Hyperion; LiPolice, OK Hobby Infinite, Shulman Aviation FURY, Gens Ace, motors etc etc)
OR: ARE KMS QUANTUM MOTORS JUST COPIES (i.e. CLONES) OF AXI MOTORS, MADE IN A QUITE DIFFERENT FACTORY ... ?
-Llke PULSO motors are just copies of AXI,-but (evidently) made in a completely different factory ...?



If indeed, KMS Quantum motors are made in the same OEM factory as AXI motors, and they turn out to be identical with AXI motors (apart from a different external colour and brand label)
-then we will have the situation that KMS Quantum motors are basically AXI motors for ~40% of the price of AXI ...




pics show: 1, 2, 3: AXI 2820/10 and 2 pics of KMS Quantum 2820/05
4, 5, 6: AXI 4120/14 and 2 pics of KMS Quantum 4120/05
7: AXI 4120/10, from rear aspect -showing that the AXI and KMS accessories (in pic 5) even look identical

Default RE: Which chinese factories make various brushless motor brands?

Great thread DoctorM
I confess I can't tell any difference between the Hacker A30 14l and 2814t 820 Torque
when fitted in my Sebart Katana.
My Thrust 30 does look different internally to the other 2 though.
As you can tell by my lekky hanger I'm not averse to spending money and was going to
buy an eflite 110 and 160 for my qq 69in yak and 2 meter Capiche 140.
I may check out the Tacon 110 first just to see.

ORIGINAL: rceccleston Thank you Dr Motor , this is a great thread
Thanks for this

... and an eye opener to the world of branding.
YES ...! I had absolutely NO IDEA that one factory in China might make all these different brands ...
-Hacker, Torque, Z-Hyperion;and Pelikan Foxy, LiPolice, OK Hobby Infinite, Shulman Aviation FURY, Gens Ace, Common-Sense-RC, Viper VA, Apache, Pilotage Nova-Line, MegaPower Taurus, Lipotech, Sonic Electric, BMI Models "Spitz" motors, Precision Aerobatics Thrust motors, Boost motors (Robotbirds), JP E-Pro motors; ELE motors (now discontinued)
AND: Turnigy SK3 motors
AND O.S. motors, Futaba motors
And Losi, Orion andHacker car motors
And "Turnigy Trackstar" carmotors
And of course: All the ESC's for most of these brands ...
And: Quite a large number of different HobbyKing ESC's e.g. Turnigy dlux ...

It is really quite amazing ...


QUESTION - Who makes the Turnigy Rotomax series?
Short answer -I don't know.
I have tried to find out, but so far, no luck. Perhaps someone reading this thread knows, and will tell us. Please.
The Rotomax motors look like a very good range, and goodquality ...

-We DO know that the GSModels factory (i.e. ZhuHai GS Model Accessories Mfg)
http://www.gsmodels.com/en/products0...me=CA%20series
make the Turnigy CA motors CA80-80 and CA120-70 -as you can see

However, at present we do not know which factory makes the Rotomax motors.


PS: We can see from the GSModels website that they make a large variety of brushless motors; but I do not obviously see the CL, D and F series motors being soldby any major retailer that I can think of ...
