I was flying my 4 day old dji spark drone in front of my.house yesterday and the battery got low and it went to return to home automatically. It was on its way well above the trees to return but then the signal was lost and it went down. I searched in find my drone and it has the red arrow. I understand that that is the last place known before signal was lost. Me and my wife searched for hours but didnt find it..there was no wind so cant see it going too far. Can anyone help me??
