A few weeks ago I purchased a DJI Phantom s/n PH63561xxxx, no version #, I just purchased another due to the price drop s/n PH63580xxxx V1.2. The s/n 63580xxxx has 2 silver prop nuts and 2 black prop nuts which are threaded differently, the 63561 has 4 prop nuts threaded the same in silver color. It seems obvious that the higher s/n would be a newer model but I have been proven wrong before. My question is what did I get a newer version or older version? I have not plugged the new one into Naza software yet to see what it says because I may want to return it if is a much older version. Is there a hierarchy to serial #'s?
