BeastX® flybarless technology is the most powerful, easiest-to-use flybarless technology flying today. And now with the amazing AR7200BX system, you can add it to your 250- to .90-size helicopter while saving space and reducing flying weight at the same time. The groundbreaking Spektrum innovation combines a 7-channel DSMX® receiver with a BeastX, 3-axis MEMS stabilization system into a single compact unit. Besides eliminating the mechanical complexity of a flybar, the BeastX technology built into the AR7200BX system lets you quickly fine-tune stability, cyclic response and tail response without touching a single linkage or require special software. All you need is your DSM2®/DSMX transmitter and this unit.
