I built this from a kit a few years ago. It is a 300 class with 8 inch props. It has a programable flight controller. The flight controller can be used on helicopters and fixed wing aircraft for stabile flight. It does come with a crash kit. It flies well. This is NOT A TOY or for a beginner flier. In has no GPS flight to help you. You must know how to fly one. Binds to a Spektrum radio.
