I have a phantom 3 ADV and am wondering if theres a trade in program? I want to trade my Phantom 3 ADV for  a Phantom 4 + cash

Yes ... it's called Craigslist

Craigslist response is valid but...
Being technology is moving so fast.... Think upgrade program would be a great idea for DJI...
Example: Trade-in price like x-amount per month technology deprecation, wear and tear based on flight data.

Should be a win win solution.  Knowing the future I would eventually like to trade my Phantom in for DJI flying car.
No ghost drone about it will happen... Just say'en
   

Doubt if DJI will ever go this route.

Truth, It would be a nice program for them

Veery dodgy. How would you know if the aircraft had been crashed or not? And what value is it to DJI? The answer is NONE. Firstly the customer would want too high a price for it as a trade-in, and to DJI a new one is probly worth a few dollars to produce. Then there is all the shipping and handling. Nah, if I was DJI I would not touch it with a barge pole.

PR value perhaps? Nope, you are going to buy your new one from DJI anyway.
