Thank you. Yeah, picture quality is amazing for a compact, but it requires some fiddling with rubber bands to keep the shutter pressed down during flight, due to lack of time-lapse. As a result, some pictures are blurry and incorrectly exposed, but usually there are keepers from every flight. At only 28mm framing is not easy, but large sensor with many pixels enables cropping and straightening in post, if you remember to keep large distance from objects you are shooting. Even though the RX 100 I is not perfect for aerial photography, I am satisfied with it and it produces much better photos than the GoPro. I guess it's one of the best cameras that can be attached to the Phantom.
I just looked around and found some wire rope mounts, but they seem to be too thick to prevent the RX 100 from protruding. Further, I suppose it would be challenging to find a good solution to attach the camera with a tripod screw, for adequate balance and ease of removal.
