The Sony RX100 functioned well except just before the balloon burst it appears the servo stopped working. Maybe because of the cold etc but you can hear it stop on the go pro video. It does start backup on the download journey but the camera will have auto powered off at this point.
It would look like i have sorted the issue with the GoPro Hero 4 Black shutting down due to heat as it ran perfect for the length of the flight. The full video can be found here
