The SC memory is a weird issue. The original photos are stored on the drone card, and duplicates are stored on the SC card. I end up deleting the copies from the SC card, although you have to watch because sometimes a photo will be on the sc card and not the drone card. Hope that helped. In regard to the flight logs, its not intuitive but as I recall you "pull down" the page from the top of the sc screen (pull dwen menu) and one of apps will be the flight logs.
I have noticed some photos get saved on the SC rather than the card, and I can't seem to move/copy them to the card. How can I get these out of the SC?
