So here's my story. Got my 1st P2V+ V2 in December. After about 10 flights it decides to imitate a flying rock. Here is the story of the death of my first Phantom about 2 weeks after I got it. viewtopic.php?f=27&t=31547 I returned it to Amazon and got a full refund. Decided to buy the "latest greatest" the P2V+ V3 model. I especially wanted the camera control wheel on the controller. I paid $250 more than the 1st one but I got all of the new features (if you can call cheaped out wiring a feature) plus another battery. Yesterday I picked up the Phantom and, based on what I have been reading for the last day about the effect of a minor tipover/prop strike burning out the ESC, can't even fly this new one! I am incredibly frustrated with DJI and totally had it with all of these quality control issues. I tried to crack open the shell tonight to see the markings on the ESC but of course I didn't have the right screwdriver to open it up. More GRRRRRRRRR. I am wondering if anyone can tell me if I have the 2.1 ESC just from the markings on the case. Model # is PV331. If that does not indicate which ESC version I have I will crack it open tomorrow to take a look. I am already expecting the worst and will, if not clearly marked 2.1, consider returning it unflown and sitting on my cash until DJI gets their crap together. Sorry for the rant. I never expected that my wallet would be 10x lighter and that I'd be 10x more frustrated before I ever contemplated buying one of these things!
