Just took my first ever flight this evening with my Phantom 4. Was quite nervous but felt I could handle the P4 as I was practicing with a cheap $50 drone and helicopter for awhile. There was little wind and the temperature is -5 celcius. I didn't do anything extreme, just testing the waters, max altitude of 63 meters and flight distance of 2236 meters. My total flight time was 19:35 and I landed with ~20% battery left. Given the air temperature I think that is a decent flight time, granted I have no experience with anything else but it makes me happy.
I used Active Track to track my wife riding on snowmobile and it worked flawlessly, even did the 360 degree shot, it looked great.
Watching the videos all I could think was, this looks like I'm watching something on the Nature channel, amazing. I'm looking forward to flying further, learning more and getting more great footage. Likely get more snowmobiling footage tomorrow.
