It is a good Quad with quality components. But they should have used some loctight as screws keep falling off from time to time.
The quad is awesome when it's flying perfectly. One time I had armed the quad and only 3 prop were spinning, I had to unplug the battery and replug and it was fine after. Another time I was flying, had rssi in the 80's then it just lost power and fell from the air. So I am unsure of item.
