I've got 2.06mile from my spark using it in FCC mode with parabolic reflactors and Yagi antenna on my controller battery will only allow maybe 500meters more if it's windless day and you have balls like yoga ballsIf you are using the Spark controller, range has nothing to do with the tablet/phone that you are using. Range for the controller is about 2,000 meters under optimal conditions. Cellular networks are not used nor needed to fly the Spark.
