I bought this package, quad is great. I'm running 4s 1300mah graphenes. 3 flight modes are dialled in straight out of the box. It is a fast, and stiff frame. Top is a bit thin, but survived a few crashes unscathed. Transmitter has good feel for the price, and starts range beeping at about 250m, so not great range, but ample for racing. Overall this is a great package and good value. I like how each component is replaceable.
