After completing the flight plan, I click on start. In the ckecklist, accuse mission is far away. Reboot the drone, control, cell phone. I tried to change the takeoff location, change the battery, and change the telephone set in which the application is installed. I calibrated the drone again. But it’s no good, continues mission is far away. The scheduled flight is 15 minutes, at a height of 90 meters. How can I solve?
My drone is a Phantom 3 standard.
