RE: Which (chinese) facctories make various brands of ESC ..?

So now what about:
ZTW-MANUFACTURED ESC's:
Now, lets look at the appearance of some ZTW-made ESC's (pic1 shows Reaper 85A ESC; pic2 shows Black Mantis 70A ESC; pic3 shows a Mystery 85A SBEC -all of these are made by ZTW)

ZTW -made ESC's usually have on their label:
Company name / Brand name / Company logo at top left of label;
They have AMP rating and whether BEC or S-BEC at top right (i.e. "85A SBEC")
They generally state "Programmable Brushless ESC" across the centre of the label;
They generally have "RoHS" and "CE" at bottom right of the label;
AND: for ESC's which are rated for 2-6 LiPo, they usually say "5-18 NIMH" underneath this (Note: NOT "6-18" but "5-18" )
ZTW ESC's generally have black motor wires.

-This label design agrees well for most of these ZTW-made ESC's: Black Mantis; Mystery Blue ESC's; JP EnErg Pro; HobbyKing BlueSeries; Reaper; Po8er ESC's; PowerHD; Jamara Xetronic; REVOXX ESCs; Cyclone Power; Maytech Harrier-Suprem (MT) V1;
And also ZTW own brand ESC's (i.e. A series and B series); and ZTW Land Power Series ESC's; -have some of these label features
-And even some HobbyKing "UBEC" models (which are also made by ZTW) have some of these label features ...
For instance, the JP EnErg Pro 110 ESC is shown in pic 4; This label of this ESC differs slightly, in that it has the model name "EnErg Pro" along the top of the label, and the company logo "JP" (=J. Perkins) at bottom left. However it still states "Programmable Brushless ESC"; it still states "5-18 NIMH" (and NOT "6-18" of Ni-anything); and it still has "RoHS" and "CE" at bottom right of the label ....

SO: We can see that there really ARE some general differences in the labelling of Sunray-made and ZTW-made ESC's;
Therefore: -If we see an ESC with yellow motor wires, it is probably Sunray made ( I have never seen a ZTW-made ESC with yellow wires)
 If we see an ESC that states "Programmable Brushless ESC" on the label -then it has a good chance of being ZTW-made (-of course much better signs are if it uses the ZTW program card, and if it has typical ZTW programming ...).
-If we see an ESC that states "Brushless Controller"rather than "Programmable Brushless ESC" -then it has a good chance of being Sunray-made (-of course a more certain sign is if it has typical Sunray programming, or that it uses a typical Sunray jumper program card ...).
-And if it is rated for 2-6 LiPo, and it states "6-18 NiCd" or "6-18"Ni-something (rather than "5-18" like all ZTW), -then it has a good chance of being Sunray-made rather than ZTW made.

It is not a foolproof method. -But it is a bit offun to look; Go on, try it yourself and see if it works ....
