last week while flying my Spark the first flight flew perfect on the second and third flight  i lost videio but i had full controll , flew it back and transmission came back then on another flight the same thing happened . i checked the flight logs and found no real errors only it set was Downlink Restored (after 0m 7.3s) and in another flight it said home port updated after i regained downlink .also the time on the file changed when the downlink was restored .not once did i get any warring ,the files are from three flight
