Moin I wished in my middle age a helicopter birthday, picked Amazon, ordered, delivered quickly. Out of sheer excitement intercepted the postman, unpacked, charged and from the Post.Sehr went quickly learned to fly it. The helicopter is very easy to use, as already described in other Rezesionen. Slowly accelerating until he begins to float, have fun and trimming. I'm almost addicted to processed very clean, robust so that he even withstand even falls from 2m. The well done with the cute lighting, oh yes, the acceleration key is to enjoy with caution. I myself have only made attempts at hold. In larger rooms, no problem.
For this product, I can only guess. Price and quality is right.
