DJI SPARK DRONE
This drone been flying for 5-6 hours and maximally achieved my expectations - see video made before selling. DJI hold a track in strong wind - TRIPOD position creating amazing videos /auto programme video camera/. About batteries, I will be honest - since new, never been working for 16 minutes, maybe on table in living room. Think about temperature, wind, maneuvering, gimbal, speed, wifi connections...
