The precision and responsiveness of BeastX® flybarless technology completely transforms any heli flying experience. The 300 CFX brings you all the benefits of this technology through the amazing Spektrum AR7200BX Flybarless Control System. The AR7200BX combines a 7-channel DSMX receiver with a BeastX 3-axis MEMS stabilization system into a single, compact unit weighing barely over 1/2 an ounce (18 g). Perhaps best of all is how simple the AR7200BX is to use. No special programming interface is needed to make adjustments. All you need to fine tune its response is the DSM2®/DSMX transmitter it's bound to.
