Hi there, yesterday my drone fell off a cliff edge 30ft .. somehow it still flies. My camera and gimbal is damaged and wondered what options I have. I think a new camera is £329 but is money i don't want to part with. So i wanted to ask. (1) is there anyway to know if the camera is broke or if i just need new outer bitd (2) i have a gopro4 - if i git a gopro gimbal would i still control photo/video from the drone ? (3) what's the different between the phantom 3 4k camera and phantom 3 pro ? Many thanks in advance.
