Worth noting these comments:

Dr Kiwi: " ... P.S. I would hazard a guess and say that the Turnigy (SK3) and the Infinite are from exactly the same factory... their appearance down to the last detail (other than the stick-on label) was the same, their Kv's were the same, and their performances were essentially identical! ..."
-This evidence shows: The Turnigy SK3 2118-2250 (17g, ~2340Kv) is an identical motor to the OK Hobby Infinite A1705-2250 (17g, ~2340Kv)</p>

Also: Dr Kiwi states: " ... The Turnigy SK3 2118-2250 (17g, ~2340Kv) seems to have similar performance to the Hyperion Z1705-11 (18g, ~2300Kv) ..."
-He also showed that the Hyperion Z1705 had identical appearance to Infinite 1705 (see below) and to Turnigy SK3 2118.

Consistent with, as we have stated above:

2nd shows pic of a LiPolice 1705 motor.
3rd shows pic of rear of a Foxy 1705 motor; 4th shows pic of front of Foxy 1705 motor.
5thpic shows a Hyperion Z1705 motor -can see front, and can just see rear nut assembly.
6th pic shows a Hacker A10 S motor-this obviously has the same front housing as the other motors, and has the same nut assembly at rear.
7th pic, for completeness, shows a Hacker A10 S motor from different website-indicating Hacker A10 can have a slightly different appearance, in different batches.
8th pic shows rear of a Turnigy SK3 2118 motor, which is also a 1705-size (i.e. has 1705 stator). 9th pic shows front of SK3 2118 motor.


It is clear that all these 1705 motors are identical. Clearly, they come from the same factory-SunRay Technology.
In addition, they allhave identical specs -for size, weight, Kv etc etc

We know that the Hyperion Z1705 motor is the same as a HackerA10 S motor, whichhas a 1705 stator.
Also, the Hyperion Z1705 motor is known to be identical to the OKHobby Infinite 1705 motor (see above).

Therefore, these pics and associated data show that, with little doubt:
Hacker, Z-Hyperion, OKHobby Infinite, LiPolice, Foxy, and Turnigy SK3 motors are identical, andare clearly made side-by-side in the same factory.</p>

<span style="font-size: small">UPDATED VERSION:
</span><u><span style="font-size: medium">A NOTE; ON THE DIFFERENT NAMING SYSTEMS / NAMING CONVENTIONS FOR BRUSHLESS MOTORS:</span></u>
Manufacturers, distributors and sometimes retailers can all use different numbers and letters and naming systems for brushless motors. -This can be very confusing. -For instance, even though a particular brushless motor may be exactly the same regarding internal components, may be made in the same factory, and may have identical specifications, it can be produced by the OEM manufacturer with different external colours, different shaped outside housings and with a different external finish. The various distributors who then "market" or "brand" this motor, can then call this identical motor by different numbers, names and codes.
This has several effects:
a. It makes it difficult for us to realise that brushless motors with different numbers and letters, names and external appearances, are actually exactly the same motor internally.
b. It makes it difficult for us to link different motors made by the same OEM manufacturing factory (-almost always a chinese factory, in 2012 ...)
c. It sometimes makes it difficult for us to choose the appropriate brushless motor for a particular plane or helicopter. For instance, the plane or heli instruction manual may recommend a motor of a particular brand, with the motor named for stator size. We may not realise that a differently branded motor, but instead named with respect to external dimensions, may be just as good a choice of motor, or sometimes a better choice, for this plane or heli.
d. We can also add the following effect: Sometimes, a manufacturer or distributor might not wish us to know which OEM factory has actually manufactured the motor, and so they name the motor with a different naming system, to try and hide this information.
-For instance, the Hacker A30-12 XL V2 motor is exactly the same (internally) as the OK Hobby Infinite 3025-770Kv 12T motor, and they are both made in the same SunRay Technology factory in China. However, the Hacker motor sells for $110 (in UK; -and $132 from Conrad UK ...!), whereas the OK Hobby Infinite one sells for $35.
-The Hacker A50-16-S-V2, motor is exactly the same (internally) as the OK Hobby Infinite A4025-370 16T motor, they are both made in the same factory. However, the Hacker motor sells for $173 (in UK), whereas the OK Hobby Infinite one sells for $50.
-The Hacker A60-20S V2 motor is exactly the same (internally) as the OK Hobby Infinite A5030-235 20T motor, they are both made in the same factory. However, the Hacker motor sells for $297 (in UK), whereas the OK Hobby Infinite one sells for $99.
-One way to hide the fact they are actually identical motors, from us gullible consumers, is to name these motors with different completely different numbers and letters -as has been done in this case -and also many other cases.
e. Distributors like to keep their "trade secrets" completely hidden from us. It has been clear for some considerable time thatHacker,Torque and Z-Hyperion motors were identical and were made side-by-side in the samechinese factory. However, what is now very clear is that this same factory is alsomaking these identicalmotors, under some otherbrand names and colours, and that these differently-branded identical motors are being sold widely for 30% to 40% of the Hacker retail price (i.e. Turnigy SK3, OK Hobby Infinite, LiPolice LP motors ...).

<span style="font-size: small">Updated version:
</span><u><span style="font-size: medium">DIFFERENT NAMING SYSTEMS FOR BRUSHLESS MOTORS:
</span></u>Here are some of the most common naming systems, or naming conventions, used for brushless motors:</p>

<u><span style="font-size: small">1. STATOR SIZE
</span></u>The stator of an outrunner brushless motor is the central non-rotating part, which is radially arranged, and which is wound with a given number of turns of copper wire. The outer can with magnets mounted on its internal face, rotates around this stator. Stator arms (also called "stator slots") are always in multiples of three -whereas motor magnets (also called "magnet poles") are always in mutiples of two.
Many manufacturers and distributors name their motors with respect to stator size; For instance AXI, Scorpion, Emax, Pulso, Suppo, Motrolfly and also some motors made in the SunRay Technology factory (e.g. Z-series Hyperion, LiPolice, Foxy, OK Hobby Infinite, -to name a few) are all named this way. Worth noting that Pulso motors are basically a copy of AXI motors, use the same stator-size naming system, and are sold in the USA (with small modifications) as Innov8tive Cobra motors. The O.S. motor naming system has a part which uses length of the stator (see later).
e.g. The AXI 2203/52 motor, has a stator which is 22mm diameter, 3mm in length, and is wound with 52 turns of wire.
The AXI 4130/16 motor, has a stator which is 41mm diam, 30mm length, and is wound with 16 turns of wire.
The Scorpion SII-3020-890Kv motor, has a stator which is 30mm diam, 20mm length; it has a Kv of 890 (-and is wound with 10 turns of wire =10T ).
The Z-Hyperion / LiPolice / Foxy / OK Hobby Infinite 2213/20T motor has a stator which is 22mm diam, 13mm length, and is wound with 20 turns of wire.
The Suppo A2820-6 motor has a stator which is 28mm diam, 20mm length, and is wound with 6 turns of wire.</p>

<u><span style="font-size: small">2. EXTERNAL DIMENSION
</span></u>Some manufacturers name their motors with respect to their external dimensions, usually outer diameter and length.
XYH (i.e. EMP), most Turnigy, Saite, Dualsky,and many other brands, name their motors this way. (-Worth noting that XYH (EMP) motors are sold under dozens of brand names -including Turnigy "standard" and Turnigy "Aerodrive XPSK" -and mostly all these brands also use this external-dimension naming convention for these motors).
Also worth noting that the Gens Ace range of motors, and also the Turnigy SK3 range of motors -even though they are both manufactured by the SunRay Technology factory, and therefore almost identical to Hacker and Torque and Hyperion motors -they use the external dimension naming system to describe their motors
e.g. The XYH N2830/13 motor is 28mm external diam, 30mm long, and has 13 turns of wire (its stator size is 22mm diam, 13mm length -same as a "2213" motor on stator-size).
The XYH N5055/07 motor is 50mm external diam, 55mm long, and has 7 turns of wire (its stator size is 40mm diam, 25 mm length -same as a "4025" motor on stator-size -see http://www.rcgroups.com/forums/showthread.php?t=1724518 ) (This motor was also sold as the old "TGY AerodriveXp SK 50-55" motor and can also be found as an "EMP 5055" motor or "N5055" motor on eBay).
(Worth noting: that some 5055-size motors have a 4030 stator,rather than a 4025 stator ... -for instance, the Turnigy SK3 5055 motors have a 4030 stator, however these motors are actually 59mm long ... -so should really be called a "5060" motor on basis of external dimensions )
The Turnigy SK3 3542-1000kv motor, is ~35 to 37mm external diam, ~42mm long (has 12 turns of wire) (its stator size is 30mm diam, 20mm length -same as a "3020" motor on stator-size). (It is the exact same motor, internally,as: Hyperion Z3019-12T, LiPolice / OKHobby Infinite / Foxy3020/12T-970KV and Hacker A30-12 L V2).</p>

<u><span style="font-size: small">3. THE HACKER MOTOR NAMING SYSTEM </span></u>
Hacker motors aremade together with Extreme Flight Torque and Z-Hyperion motors, in the SunRay Technology factory. They are identical internally and also in specs to Torqueand Z-Hyperion motors, and also to the other motor brands made by the SunRay Technology factory. They have a slightly different external can appearance to Torque,Z-Hyperion and the other motor brands -thisis just cosmetic, and the external can shape and colour has no relation to motor performance.
Hacker uses a different and seemingly unique naming system. The first number reflects power level: "20" motors seem to refer to roughly an I.C. 20-size power level, "30" motors refer to I.C. 30-size in power level; whereas "50" refers to I.C. 50-size power level, etc etc.
The second number in the Hacker naming system, refers to the number of turns (winds) of wire on the stator. The final letter in the Hacker name, refers to the length of the motor -either S, M, or L (small, medium, large) (or: short, medium, long).
(Note: Keda motors are basically -poor-quality -copies of Hacker motors, and since they are copies, they also copy and use the same Hacker naming system ).
For instance, the Hacker A10-9L motor, is "10" size, has 9 wire turns, and is "L" -22mm long (its stator size is 17mm diam, 9mm length -same as a "1709" motor on stator-size) (its external size is 21mm diam, 22mm long -same as a "2122" motor on external dimension) (It is the exact same motor as the Hyperion Z1709-09T, LiPolice / OK Hobby Infinite / Foxy1709/9T-1580KV and Turnigy SK3 2122-1570kv, 9T).
The Hacker A30-12-L-V2 motor, is "30" size, has 12 wire turns, and is "L" -42mm long (its stator size is 30mm diam, 20mm length -same as a "3020" motor on stator-size) (its external size is ~35mm diam, ~42mm long -same as a "3542" motor on external dimension) (It is the exact same motor as the Hyperion Z3019-12T, LiPolice / OK Hobby Infinite / Foxy3020/12T-970KV and Turnigy SK3 3542-1000kv, 12T).
The Hacker A50-16-S-V2 motor, is "50" size, has 16 wire turns, and is "S" -52mm long (its stator size is 40mm diam, 25mm length -same as a "4025" motor on stator-size) (its external size is ~50mm diam, ~50mm long -so about the same as a "5050" motor on external dimension) (It is the exact same motor as Hyperion Z4025 16T, LiPolice / OK Hobby Infinite / Foxy 4025 /16T-385KV).</p>

<span style="font-size: small"><u>4. THE O.S. MOTOR NAMING SYSTEM
</u></span>The O.S range of motors also appear to be made in the SunRay Technology factory.
O.S. uses another motor naming system, which combinesmotor external diameter and stator (i.e. magnet) length. The first number refers to motor external diameter inmm, and the second number refers to stator (magnet) length in mm. It has some similarity to the Himax naming system (see below).
For instance, the O.S. OMA-3815 motor is 38mm external diameter, and has a stator (magnet) length of 15mm. It is 38mm long, has a weight of 130g and has 16 turns (its stator size is 30mm diam, 14 to 15mm length -same as a "3014" motor on stator-size); (its external size is ~38mm diam, ~36 to 38mm long -so about same as a "3838" or "3836" motor on external dimension); (It is a similar motor to: Hacker A30-16 M V2, Turnigy SK3 3536-1050kv,Hyperion Z3013-16T andLiPolice / OK Hobby Infinite / Foxy 3014/16T-972KV).
The O.S. OMA-5025 motor is 50mm external diameter, and has a stator (magnet) length of 25mm. It is 58mm long, has a weight of 400g. (its stator size is 40mm diam, 25mm length -same as a "4025" motor on stator-size); (its external size is 50mm diam, ~55 to 58mm long -so about same as a "5055" motor on external dimension); (It is a similar motor to Hacker A50-16 S V2, Hyperion Z4025 16T, and LiPolice / OK Hobby Infinite / Foxy4025 /16T-385KV).</p>

<u><span style="font-size: small">5. E-FLITE MOTOR NAMING SYSTEM
</span></u>E-Flite name their motors directly, with respect to their equivalent I.C. power level. E-Flite motors are all made by the ChinaHimark factory, in China -they are all ChinaHimark "C-Type" motors.
E-Flite motors have identical specs to the "TACON" outrunner motors sold by Hobbypartz.com (The TACON motors have a different external can and colour -this is just cosmetic) and so it appears that TACON motors will also be made by the ChinaHimark factory.
For instance, the E-Flite Power 10 motor is 35mm diam, 43mm longand has a Kv 1100 (its stator size is 28 to 30mm diam, 20mm length -same as a "2820" or about "3020" motor on stator-size) (its external size is ~35mm diam, ~42mm long -same as a "3542" motor on motor external dimension). (It appears to be the same motor as theTacon "Big Foot 10"2820 1100Kv and Turnigy G10 EasyMatch 1100kv).
The E-Flite Power 46 motor is 50mm diam, 55mm long and has a Kv 670 (its stator size is 40mm diam, 20mm length -same as a "4020"motor on stator-size) (its external size is ~50mm diam, ~55mm long -so same as a "5055" motor on external dimension) (It appears to be the same motor as the Tacon "Big Foot 46"4020 670Kv and Turnigy G46 EasyMatch 670kv).
Turnigy "EasyMatch" G-series motors also use the same power naming system as E-Flite, relating the motors to their equivalent I.C. power level. The Turnigy "EasyMatch" motors are probably also made by the ChinaHimark factory, in China, and appear to be identical to E-Flite motors.</p>

<u><span style="font-size: small">6. HIMAX / HIMARK MOTOR NAMING SYSTEM </span></u>
HiMax (also called "HiMaxx" and "HiMark") motors are also manufactured by the ChinaHimark factory, in China. They are distributed in the USA and in Europe by the Maxxprod company, and are sold in Europe as Multiplex Himax, TopModel XPower, and JP Energ C-type motors -these brands are all the same motors. These motors all use a different naming system, which is a hybrid of other systems already mentioned. The first number in the name shows the diameter of the motor, and the second number shows the length of the stator. The third number after the dash, shows the number of turns for each motor.
For instance, the Himax/XPower C2812-26 is 28mm external diam, has a stator of 12mm length, and has 26 wire turns and a Kv 900(its stator size is 22mm diam, 12mm length -same as a "2212" or about "2213" motor on stator-size) (its external size is ~28mm diam, ~30mm long -same as a ~"2830" motor on external dimension) ( -This is the same motor as the E-Flite Park 400, 920Kv motor).
The Himax/XPower C5020/14 is 50mm diam, has a stator of 20mm length, and has 14 wire turns and a Kv 670(its stator size is 40mm diam, 20mm length -same as a "4020" motor on stator-size) (its external size is 50mm diam, 55mm long -same as a "5055" motor on external dimension) ( -This is the same motor as the E-Flite Power 46 670Kv; and also same motor as: Turnigy G46 EasyMatch 670kv; (-theseare a similar, but not identical motor,to theTacon "Big Foot 46"4020 670Kv motor -because Tacon motors are made by the XYH-EMP factory, are identical to Exceed-RC "Monster Power" motors ... ).</p>

<span style="font-size: small"><u>7. TORQUE MOTOR NAMING SYSTEM
</u></span>Extreme Flight "Torque" motors are, of course, made together with Hacker and Z-Hyperion motors, and other motor brands, in the SunRay Technology factory. They are identical internally and also in specs to Hacker, Z-Hyperion and other brand motors. They have a different external can appearance to Hacker and Z-Hyperion, which is just cosmetic, and the external can has no relation to motor performance.
The naming system for Torque motors is confusing, and gives relatively little useful information about the motor. Some Torquemotors are named with reference only to number of turns and Kv; Other motors are named with reference to approximate stator diameter, as well as number of motor turns and Kv.
For instance, the Torque 20T/1030 motor has 20 wire turns and a Kv of 1030. It has a weight of ~55g, external diam of 28mm and length of 30mm (its stator size is 22mm diam, 13mm length -same as a "2213" motor on stator-size) (its external size is 28mm diam, 30mm long -same as a "2830" motor on external dimension). ( -It is the exact same motor as: Hacker A20-20-L-EVO, Kv 1022, 20T;OKHobby Infinite/ LiPolice / Foxy 2213-1080Kv 20T; andTurnigy SK3 2830-1020kv, 20T)
The Torque 2814T/820 motor: the 1st number is "28" -actually it has a stator diam of 30mm; It has 14 wire turns, Kv of 820, weight of ~143g, external diam of 35mm and length of 42mm (its stator size is 30mm diam, 20mm length -same as a "3020" motor on stator-size) (its external size is ~35mm diam, ~42mm long -same as a "3542" motor on external dimension). ( -It is the exactsame motor as: Hacker A30-14-L-V2, Kv 800, 14TandTurnigy SK3 3542-800Kv 14T)
The Torque 2812T/720 -also has stator diam of 30mm, but with 25mm length; It has 12 wire turns, Kv of 720, and aheavier weight of ~177g, external diam of 35mm and length of 48mm (its stator size is 30mm diam, 25mm length -same as a "3025" motor on stator-size) (its external size is ~35mm diam, ~48mm long -same as a "3548" motor on external dimension). ( -It is the exact same motor as: Hacker A30-12 XL V2, Kv 700; LiPolice /OKHobby Infinite/ Foxy 3025-770Kv 12T; andTurnigy SK3 3548-700kv, 12T ).</p>

<u><span style="font-size: small">8. PJS MOTOR NAMING SYSTEM
</span></u>PJS brushless outrunner motors are named very simply, according to the amount of static thrust that they are capable of producing. Of course, in practise the amount of thrust depends critically on the prop used, and number of Li-Po's used -so it is not necessarily a useful or accurate naming system.
e.g. The PJS 3D 300 SFR motor, is for indoor models. It produces 300g of static thrust; It is heavy by the standards of today -weight 36.5g; Kv 1210; external diam 32, length 45mm.
The PJS 3D 1500 motor, is for park flyers. It produces 1500g of static thrust; Weight 131g; Kv 765; external diam 40, length 45mm.
The PJS 3D 3000 motor, is suitable for 50-size models e.g. the Sebart Angel 50. It produces 3000g of static thrust; Weight 345g; Kv 496; external diam 53, length 46mm.
PJS produce a very large range of motors, from small 36g motors -up to very large 1,550g monster motors using 30 inch props which produce up to 18kg static thrust - see http://www.pjs.cz/index.php?cPath=1&amp;...=2a&amp;page=1</p>

<span style="font-size: small"><u>9. MEGA MOTOR NAMING SYSTEM
</u></span>Mega outrunner motors have a naming system which is a little different to others. Some motors are named with reference to the older brushed motors. Other larger motors are named with reference to stator size and number of turns.
e.g. The Mega RC 600/10/8 motor: is equivalent to a 600-size brushed motor; the 2nd number "10" shows a stator length of 10mm, the 3rd number "8" shows it has 8 turns. Weight 85g, Kv 1695, diam 36mm, length 35mm (its stator size will be 30mm diam, 10mm length -same as a "3010" motor on stator-size) (its external size is ~36mm diam, ~35mm long -same as a "3536" motor on external dimension).
The Mega RC 41/30/15 motor: 1st number shows stator diam 41mm; 2nd number "30" shows a stator length of 30mm, the 3rd number "15" shows it has 15 turns. Weight 499g, Kv 410, diam 49.3mm, length 52mm (its stator size is 41mm diam, 30mm length -same as a "4130" motor, or ~4030, on stator-size) (its external size is ~50mm diam, ~52mm long -same as a "5052" or a ~"5055" motor on external dimension).</p>

<u><span style="font-size: small">10. MVVS MOTOR NAMING SYSTEM </span></u>
MVVS uses a different motor naming system to that of any other company. Each outrunner motor is designated with a 1st single number, signfying size of the stator, and the Kv. A list of the motor numbers is shown below, showing the stator size that this number refers to.
e.g. The MVVS 2,0/1120 has a stator diam 26mm, length 9mm, and Kv 1120. Weight 87g, external diam 36mm, length 31mm (-same as a "2609" motor on stator-size) (-same as a "3630" motor on external dimension).
The MVVS 8.0/680 has a stator diam 36mm, length 20mm, and Kv 680. Weight 223g, external diam 44mm, length 46mm (-same as a "3620" motor on stator-size) (-same as a "4446" or ~"4250" motor on external dimension).
For MVVS motors:
No Stator diam Stator length
2.0 .... 26 mm .... 9 mm
2.5 .... 26 mm .... 13 mm
3.5 .... 26 mm .... 18 mm
4.6 .... 26 mm .... 26 mm
5.6 .... 26 mm .... 36 mm
6.5 .... 36 mm .... 15 mm
8.0 .... 36 mm .... 20 mm</p><div id="fb-root" class=" fb_reset"><div style="position: absolute; width: 0px; height: 0px; top: -10000px"><div></div></div></div>

<span style="font-size: small">HACKER, GENS ACE AND TURNIGY SK3 ARE IDENTICAL MOTORS
</span>
I have purchased several Hacker, Gens Ace and Turnigy SK3 motors for comparison.
Pics show 3 motors, all of 55g weight, Park Flyer size:
Hacker A20-22 L-EVO, Kv 925, 22T
Gens ACE Mars BL2726-960KV, 22T
Turnigy SK3 2830-920kv, 22T

These motors are all suggested to be made by the SunRay Technology factory. They all have a 2213 stator.
You can see from the pics, that they have identical stators, and windings and bearings. This is also clear from the end-view of the stators.
These motorsalso have identical magnets, and number of magnets.
In addition, the connecting leads, the plugs and way the leads and heat shrink cover are arranged, is identical for each motor.

They all appear to be identical, as far as the internal working parts are concerned. The outer housings may be a slightly different shape, the outer colour different, but this is just cosmetic, and has no effect on motor performance.

<span style="font-size: small">quod erat demonstrandum ... ?</span></p>

FURTHER INFORMATION:
In addition:
1. The Hacker motor has an IDENTICAL front housing to the Turnigy SK3 motor.
The only difference is that the Hacker front housing is black, whilst the SK3 front housing is silver.</p>

2. The Hacker and SK3 (and also Gens Ace) motors also have an identical rotating can -in both length and metal thickness,and magnets and magnet placing. The magnets for each motor are also slightly curved.
Once again, the only difference is that the Hacker rotating can is purple on outside, whlst the SK3 can is silver(and the Gens Ace is black).

From these spec sheets, you can see very easily that ALL theLiPolice / Pelikan Foxy /OK Hobby Infinite motors have <span style="font-size: small">exactly</span> the same naming system as SunRay, and that all their specs are <span style="font-size: small">completely identical </span>to all the SunRay motors.

Seems that Mr Hacker has copied the Novak car motor ...</p>

May be relevant to the above post, to show the followingcomments: -originally made by Christian Lucas, in Germany:
http://www.rcgroups.com/forums/showp...;postcount=206
-He gives the opinion that Hacker does not really have their own motor designs, they just copy from others. He calls Hacker a "German Copyshop".
He states that Hacker outrunner motors are just a copy of Plettenberg motors. Evidently this is what Uwe Plettenberg himself says.
And it is very clear, for instance, that the Hacker Q60-7M F3A is just a copy of the Plettenberg Xtra 30 motor, with the Q60 having a purple colour on the outside, and a slightly different can with a removable rear end housing.

Christian also states that all Hacker inrunner motors are just a copy of Lehner motors ( -and from the above comments, the Hacker inrunner car motoris acopy of the Novak motor ... )

-I have also heard several other people give similar views about Hacker motors.

Certainly, we know from the evidence in this thread, that Hacker outrunner motorsare exactly the same (internally) as:Torque, Z-Hyperion,

If anybody reads that entire thread instead of the one he linked to you may note all the suspended accounts are from this guy!
Same BS, no actual proof the motors are the same from actual testing. Many motors are made in the same plants to different specs, N50 vs N30magnets, cheaper windings that have a lower grade of insulation, cheaper magnets, cheaper shafts, not as well balanced, the list of places they can save a few bucks is almost endless, stator laminations......
Just because the Chinese copy or manufacture something that looks the same as somebody else's product does not mean it's made to the same quality.
We've all experienced the cheap chinese knockoff. They made it famous!
The only way this thread can have any validity is if this guys actually buys tests and disassembles the motors he is all claiming are the same.
Do SOME of them look the same yes, are the guts the same, I doubt it!
LOL he is even no claiming that motors with MINOR differences in the cases are the same.....
Sad joke!
The fact is there are not that many plants making motors for us in china, of course some motors are made in the same place, all to the same specs - NO!
All you have to do is go to the Hacker webpage and note that Hacker sells all the replacement parts for ALL of their motors. That is just one of the things you are paying more for, crash a hacker outrunner, bend a shaft, order a new shaft and your going again, the cheapies - buy a new motor!
http://www.hacker-motor-shop.com/e-v...=3&c=441&p=441
here is the hacker parts listings for the A30 series.
Draw you own conclusions based on this evidence from the Hacker page. Might be made in China but I guarantee to different specs.

In fact if you read that entire thread, (I just did) http://www.rcgroups.com/forums/showt...4#post21396796
Dozens of people in there asked for the same simple thing I've asked for, numerical proof not dimensions from a motor add!
Completely ignored all those requests and just kept on with they "look the same so they must be the same" No testing or actual proof was offered in that thread, just more looking at pictures and making an assumption - Then posting it as fact!
Show me the facts not just supposition based on pictures and the weight and dimension of a motor! No surprise that motors of the same "class" share the same dimensions and weight!
Where is the actual REAL test data?

<span style="font-size: small">LIPOLICE, PELIKAN FOXY AND OK HOBBY INFINITE MOTORS -ARE IDENTICAL<span style="font-size: x-small">

3rd pic shows Lipolice 5045 motor (~6374 size on external dimension; similar to Hacker A60-L motor)
4th pic shows an OK Hobby Infinite 5045 motor.

Clearly, the Lipolice 5025 motor is identical to the Foxy 5025 motor.
And the Lipolice 5045 motor is identical to the OK Hobby Infinite 5045 motor(even the rear mounting plate is identical ...) (-the Infinite motor has a very slightly different front housing) (-this shows the previous "Scorpion-like" gold / black scheme of the OK Hobby Infinite motors ...).
Obviously, this shows that Lipolice, Foxy and OKHobby Infinite come from the same factory. There is no doubt at all.

What the manufacturershave done, is to slightly alter the outer appearance of these different motor brandsfor the smaller 20-size, 30-size and 50-size motors. Inside, of course, all the Lipolice, Foxy and OK Hobby Infinite are identical, and they have the same quality and performance.
However, they have not altered the outer shapeof these 5025 and 5045 motors-showing the common and identical heritage of these 3 motor brands.

And, of course, Puffin Models website actually states: <span style="font-size: small">"Pelikan Foxy Brushless Motors .... are produced by the manufacturer of Hacker outrunner motors"</span> - http://www.puffinmodels.com/category.php?dept=281

So:We can be certain that Pelikan Foxy, LiPolice, OK Hobby Infinite motors are produced in the SunRay Tech factory,
-and that they are identical(internally) and in performance toHacker, Torque, Z-Hyperion, Shulman Aviation Fury,Gens Ace motorsetc etc,

<span style="font-size: medium">-TO SHOW HOW IDENTICAL MOTORS CAN BE MADE TO APPEAR DIFFERENT MOTORS TO THE CONSUMER ...</span>

This shows how Sunray Technology attempt make the same motor"look"a little different for each brand they manufacture.

Very clearly,they are all basically identical 2213 motors,made in the same factory-of course, we know that. -The only real difference is that the Infinite motor has grey end housings; whilst Lipolice has green, and Foxy has blue ...
-And we can see very clearly, that the Lipolice and Foxy motors are identical when viewed from the front aspect (pics 4 &amp; 5) (very minor difference in machining ...).

What the Sunray Tech factory have done, to try and make them look like different motors,is simply to make the shaft come out ofeach motor at different ends-to create the illusion that they might somehow be different motor brands,and not be related in any way ...
For the OK Hobby Infinite motor,the shaft comes out of the "back" end housing,and so they canphotograph the motor from this back aspect(i.e. pic 1).
For the Foxy 2213 motor,the shaft comes out of the "front" end housing,and so they photographTHIS motor from the front aspect -and create the illusion that it might bea different motor in publicity photos (i.e. pic 5).-If yousaw pics 1 and 5 side by side, you would never guess that these were completely identical motors,made side-by-side in the same factory, with identical internal components ...
And for the Lipolice 2213 motor,the shaft is placed in mid position, coming partly out of the front,and partly out of the back ....! (pics 2 &amp;4)
(-of course, the position of the shaft in any outrunner motor can be altered, simply by loosening the allen screws and pushing it through ...)

So what Sunray Techhave done,to try and make these identical motors appear to look different for each different brand:
-For one brand, they image motor from frontand change the colour of the end housings
-And for another brand, they image the motor from the back and have a different colour again for the end housings ...
-And in some cases, they also machine the end housings in a slightly different style( -as wasdone, for instance,with Hacker and Torque and Z-Hyperion motors -they are all identical motors,they just havedifferent colour end housings machined in a slighly different style,they have the rotating can painted in different colours -and of course, a different brandname on the outside)</p>
