</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 ...).
