It's random , and will go off to red sometimes when I try everything , by that time my animals I'm looking at have disappeared. getting frustrating . Turn controller on and some times it's red but when I really need it it will flash blue and won't fly . Red means it's good to connect . Tried downloading refresh programs . spent hrs on it and now a week . mucking around . Anybody heard of this ? I am in the desert and no Wi Fi , is that the problem ?
