Hi, I mounted the F1 on the wing of a RC plane and set for Record/Photo. After I landed I refueled and set the recording for straight video and took off again. I also made a video on the plane facing backwards. When I reviewed the videos after, I saw that the first recording had stopped about 11 minuites into the flight so I missed the landing. It was not a battery issue because the second and 3d recording worked well for the entire flight with no issues. Any ideas about what happened?
