Today here in China DJI is offering to recycle your Phantom 3 against a new P4. Its only currently available here in China if you look at the DJI web site as a Chinese version. I tested the offer and found a P3A in good working order and everything still in good working order an offer of $405 was made subject to factory inspection. I bought mine direct from DJI here in China and as i speak Mandarin have had the best support available. What they do with the old P3A i don't know maybe used to exchange with broken ones Exchange turn round not quoted extra battery not included in the offer :-( Pity the offer isn't against an Inspire Pro RAW which i like very much apart from the ludicrous price.
