Hello, I already said I fly with a drone of 9 kg. recognized by Italian FAA so I can get permission to fly in areas around airports. With my new Phantom 4 (This phantom is not yet authorized for aerial work) but I wanted tried to fly into a no-fly zone just to see if I could activate it. This has been successful but the Dji Go App ask me my telephone number , and my credit card number. I did this, and I could fly. The flight was only a test I flew less than a minute to a height of 15 mt. 3.7 miles from the airport. The question is: what it means send to the Dji My credit card data? Ta!
