An excellent quadric, for me, as the owner of the first quadric in my life, an ideal option, a lot of different protection against collisions, flying around obstacles, etc. . From myself, I highly recommend taking the FLY More combo right away. I myself regretted the money and now I regret it, at least the bag from the kit is an extremely necessary thing. Flight radius - up to 2.5-3 km in the city (tested from the balcony of the high-rise landing). Of course, it all depends on the obstacles and the noise level of the air. For a long time I could not connect my Nexus 6p to the headset - I simply did not see the connection program. What has revealed - it's not clear, either ating the firmware, changing the cable from the bundled one to your own, or turning off USB debugging on the phone. Also from the jambs - during the flight, about a minute on the 15th, the software hangs and with it the whole phone, while the phone is rebooting - the quadric hangs in the air, if you do not order it to "fly home". Partially helped the inclusion of the air mode on the phone.
