Going flybarless is a great way to unleash the animal in any 3D helicopter. By eliminating the mechanical complexity and weight of a flybar, you get faster head speeds and lighter disc loading.

This translates into a helicopter that’s much more eager to perform aggressive 3D manoeuvres.

The BeastX™ 3-axis MEMS flybarless stabilisation system is the most powerful flybarless technology available today. Its unrivaled responsiveness and precision completely transforms any 3D flying experience.

Now BeastX technology can be added to most any 250- to .90-size helicopter, while saving space and reducing flying weight at the same time, with the Spektrum™ AR7200BX.

This groundbreaking innovation combines a 7-channel DSMX™ receiver with the BeastX system into a single, compact unit that weighs a minimalist 18 grams. It also has an incredibly small footprint, so it’s easy to find mounting space on even the most crowded heli frames. Perhaps best of all is how simple the AR7200BX is to set up.

Because BeastX flybarless technology doesn’t require a special interface to make adjustments, It can easily be tuned to a heli’s response at the field using just the AR7200BX unit and a DSM2/DSMX computer transmitter with heli programming.
