The build quality is top, the accessories such as replacement blades, SD Card inkl.Kartenleser etc. is excellent. It has a camera on board that can be operated from the FB out fine. In the house he can fly very well. So far so good. In the description, however, advertised that it was the first helicopter to be even able to fly in the wind - but the reality is different. In practice, it blows to the helicopter at the slightest breath of air, the tail rotor is also much too small to be able to control contrast. Thus, it is good actually - if not absolute wind at all - only "indoor", making it unusable for me, I wanted to let fly in my garden him. I have returned the helicopter and will yet make up my mind now for a Quadrocopter.
