I am purchasing some spare parts for my Phantom including a CW and CCW motor.  Can someone tell me if I received the right parts?  How can I identify the correct (upgraded) motor for the DJI Phantom Vision 2+ V3 ??  I do not trust the packaging, is there a way to identify by examining the actual motor?  

It should look like the 2312 on top, not the one below with the different base. But it probably won't have the numbers on it.
