During my first flight with my new C-Fly drone I found, that it is really very good drone especially for beginners. I was using the settings of the video to 2.7K resolution and I was flying fluently because of only 25 pcs/sec video. This video is in 4K resolution, but it has only 15 pcs/sec, it is too low for practical using. That is why I was flying very slowly during this flight.
