This is the Spektrum AR7200BX 7CH DSMX Flybarless Control System. BeastX flybarless technology is the most powerful, easiest-to-use flybarless technology flying today. Now with the amazing AR7200BX, 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 lets you quickly fine-tune stability, cyclic response and tail response without touching the linkage or requiring special software. All you need is your DSM2/DSMX transmitter and this two-in-one unit!
NOTE: 500 class and larger helicopters require a DSMX remote receiver (SPM9645) (not included).
