I bought this Drone today and was enthusiastic at first. It stands on its own in the air and stabilizes each Influence (wind) outside. You can fly very well and makes great shots (although I found the images that exist partly on Youtube a little better). On my third flight to Akkuwechesl the Drone is but like at 30% battery suddenly like a stone from the sky! In the app was a bit of connection to engine 4 disturbed or so ähnlich.Der battery had been place after the fall and the drone had been forced to insert every single time. On the Internet, I then read that this error is not unknown and Handle multiple users described the same problem. I was then on the same day directly back from the merchants and have returned the Drone. I will indeed buy me via Amazon another, have, however, been some concerns about flying again at high altitude.
