hello my question is how the flight distance here in the left of the screen is calculated? because the time i now was online it even become more. is this because i sync the data of my drone? so yes why is the data here more realstic then on my i pad? because i lost the flight data from my old drone overthere? ps my charging times of my battery are less then the flight times and battery's are from previous drone. so it need at least more. can anyone clear the things for me? thanks
