With it's advanced gyro and balance bar technology, the F645 F-Series single rotor rc helicopter brings stability and ease to the market.  This 4 channel RTF RC Helicopter would be considered an entry level or trainer single rotor helicopter, for pilots who want to begin flying more advanced helicopters.  Built of durable crash resistant materials it is a great heli for beginners and manuverable enough for even more experienced pilots.  It would be the perfect upgrade from a 3 channel helicopter (9053, 9101, 9104) since, its fourth channel allows it to handle better outdoors.  The RTF kit comes with everthing you need to start flying, including a 2.4Ghz transmitter, lithium battery, charger, transmitter and a replacement tail rotor.
