SunnySky X2212 980KV

I have been hearing quite a lot of nice things about the SunnySky X series and when searching the internet and comparing the NTM 2826 that i have with the SunnySky's equivalent, the conclusion is that the standard bearings on the SunnySky are way better, more efficient and give an increased flight time. Here is just one such review. I figured that i ought to upgrade my motors and try these out. As you might know i like to buy a lot of stuff off Ebay and i am well aware of the fact that some of the quality is rubbish, brand products are often copied, sold at a cheaper price and the quality is nowhere near the original product. Most of the stuff i purchase is actually cheap and inexpensive stuff like, props, screws, tools, cabling and so on, so if the quality is bad, then what the heck. Expensive stuff like motors, ESC' s, flight controllers i will usually purchase at a more reliable source to have some assurance of the quality.

Upon searching Ebay for the SunnySky X2212 980Kv, a heap of motors came up, all claiming to be original, well at least they had the original photos of the motor, taken off SunnySky's web page. I searched the the internet for "fake X2212 980Kv" and found a few blogs where a discussion was going on about a load of fake SunnySky motors.

Link to RCgroup discussion on fake motors.

This made me forget my idea of ordering these off Ebay as apparently even well renown places like goodluckbuy.com and banggood.com were selling these fake motors. I decided that i would try to email a seller from ebay and asked him if his were genuine and made him aware of the fact that i knew there were counterfeits around and would demand a refund if i received a fake. He assured me that he did not sell fakes.

I don´t have the fake motor to compare with, so I did some research and then ordered one motor, just to be sure and if his product lived up to the specifications i could order the remaining at a later stage. The motor arrived after just a week and a half which was pretty fast.

Upon examining the box and comparing it to the data in RCgroups the box looked like a fake as they state that the original packaging is to the right, the outside wire is blue.
 On my package the outside wire is red, so i assumed that this was a fake.
But according to Sunnysky their packaging is done in heat sealed thick plastic and not in zip sealed thin plastic Note from Sunnysky mine came in a heat sealed bag. So this kind of gave me some hope, that it was in fact genuine.
The motor arrived in thick and neatly heated
plastic bags 
Fake  motors often come in thin zip tied plastic bags.

 One of the other things to look for is the heat shrink that tucks the wiring into the motor housing, this is nicely done and very clean, the heat shrink goes all the way through on the fake products the heat shrink is not very neat
The motor i received was very neat, the heat shrinks are tidy in all places.

Original is on the left, notice the poorly done heat shrink
The heat shrink on the bullet connectors is also well done with good looking and quality bullet connectors 
These are the bullet connectors on the motor i received.
This image is taken off the RCblog and shows the difference in quality the original is the right

 The bearings on the motor i received look original and measured  9.52 with a caliper


The fake one are a bit smaller.

 The windings should be neat and well made. They look very tidy and well done on the one i received.

 This RCblog photo shows the difference

 The font used also tells you of the originality, on some fake models you can see the different fonts used in the S, the motor i received has the correct font.
Other things look for

I then download the motor specifications from SunnySky´s webpage and simply measured all the parts and everything seems to be in order, so my guess is that this is the genuine product. The only difference i saw was the box. So this is either a very well made fake, or an original in new packaging.
But i can in no way confirm wether this is an original or just a well made fake. Either way, the motors perform well, so all the same, been using them for a while and they do run smooth. One of my blog readers finally found the evidence that proves these are fake, thanks to papadkostas for pointing it out, the web adress at the bottom has a small space between the sky, Kostas received a batch of three motors with one of them having defect bearings. So would not recommend this unless you are willing to take a risk. These seem to be very well made fakes.
