So i got the spark instead of mavic being a first time drone owner i thought 2 km would be enough range and traveling a lot the spark would save on weight and space but i am thinking i made the wrong choice using phone i only get 30 meters at best and using rc with otg only 100 meters of a supposed 2000 meters and this is in clear field with no power or wifi within 300 meters i spoke to dji but they basically said its not their problem when i get home i think i may sell it and go to different brand of drone as dji is no help what so ever with after sales support
