Gaui X7
Bought at the beginning of 2016 - new kit along with all the setup. Fulfilling a dream of flying a 700. First flights were in march 2016. It flies two 6S LiPo batterries, such a set is enough for a 4 - 5 minute flight, depending on the condition of the batteries and fight style. During the years I tried a few vendors - like Turnigy, GensAce and SLSach. There was only one serious crash once, when an FBL controller unmounted mid-flight. For a long time there were some issues with the motor: model would disable the motor ocassionally (fortunaltey - always right before landing) and wouldn't keep steady RPM. I just re-soldered the whole battery - ESC - motor circuit and the issue went away. I guess my initial soldering was lame ;-) And for the RPM: properly setting up the ESC (especially governor) and switching to better batteries did the job.
