Good News!!! After several back and forth emails and a few photos DJI has confirmed I have the correct no version ESC's installed!!! Just email them your concern and provide the Pahntom S/N on the aircraft body and/or wi fi S/N and they will tell you whether you have a problem. Here is a cut and paste from my DJI email:
My original inquiry:
I purchased two Phantom Vision + version 3.0 directly from your DJI website in November. I am member of the DJI Phantom 2 forum and I am aware that there are some problems with Electronic Speed Controllers (ESC's) and that some Vision + Ver3.0 do not have the correct ESC's installed for the V3.0 2312 motors, and are going bad. One of two phantoms I purchased has no version number on the ESC bar code stickers, where apparently the correct and updated ESC's have Version 2.0 or 2.1 printed on them. I have attached a picture of the esc.
I have been advised by others who have done so, to contact DJI in regard to this.
Could you please clarify this for me, or confirm that my aircraft has the correct ESC's installed. I have been told that DJI can verify this by means of the serial number that I have provided below. Thank you.
DJI response:
Thanks for contacting DJI.
Regarding your concerns, please kindly send us the SN number on either WIFI Extender or the aircraft body for our better analysis and troubleshooting.
We'll follow up your problem soon after getting your feedback.
and finally after sending them the information they requested i just got this today:
