Hi everyone, just a general question I hope I can get some insight on. My father-in-law loved drones and had a phantom 1, phantom 2 that he flew quite often. He had just gotten a Phantom 3 advanced when he got cancer and passed away. The phantom 3 has never even been out of the box. I know very little about what it would be worth to sell and where I should go to try and sell it. Any advice would be much appreciated
