Hi everyone. New Spark pilot and new here. Been flying for about a month now and enjoying it a lot. No issues so far......until yesterday. I fly it over the water a lot while boating but thankfully that wasn't the case yesterday. I was video recording some beach footage, flew it out about 200 feet, maybe less and it suddenly started landing on its won. I noticed that I might have lost Wifi signal, battery was almost full. I was able to locate it, thankfully I was nearby at the beach and not flying over water. I'm surprised I lost wifi, it was a residential area on an island. My question is......shouldn't the Spark fly back to me when it lost signal instead of just landing all of the sudden on its own? I'm still learning so your help would be greatly appreciated. Thanks in advance.
