Well, as you see today it's one of nano drones, the X31 is a nano SY drone that this great, compact and can easily carry in his command. We have it in two colors, black and white, at an incredible price of 13 € about this nano drone is a safe bet to take some good times. With a 3.7 v battery incorporated giving us a flight time of between 6 and 7 minutes, slow to load about 35 to 40 minutes.
A stable, tough enough and although the small size that has drone can fly outdoors, as it can with small air breezes, as you can see in the video.
Perhaps one of the best nano drones this stylish, compact and versatile, with very good handling and a headless mode and return home to work quite well, within the constraints of the drones without GPS. A drone that reminds me of the small Xinlin one of my favorite nanos.
