I have flown Phantom 2 with gopro, Phantom 3, Mavic Air 1 in the past. For me, the main and main improvement is the CAMERA. She is wonderful! Finally, it became possible to shoot high-quality photos and videos during normal hours and even after sunset (not in the city, where there is a lot of artificial lighting, but in nature!) The camera is a huge breakthrough compared to my old Air 1. In terms of speed and controllability, things have become much better with this drone. Overall, feeling more in control while flying
