AS3X System

Agility and Stability in Perfect Harmony

Since the beginning of aeromodeling, agility and stability have been at odds. Build a model to be more stable and you lose some of the crisp response you need for aggressive aerobatics. Make a plane more agile and you'll find yourself working harder to keep it in a desired attitude. No more! With a Spektrum™ receiver equipped with the AS3X (Artificial Stabilization – 3-aXis) System, you can expand a model's agility and stability without having to sacrifice either.


How It Works

The AS3X System works behind the scenes to stabilize an airplane in whatever attitude you command. It does so using a combination of sophisticated 3-axis sensing technology and exclusive flight control software tuned by expert RC pilots.

In a 3D aerobatic model, the AS3X System makes slow speed and knife-edge maneuvers feel much more stable even when the pitch and roll rates are set extremely high. In a scale park flyer or ultra micro, it will counter the effects of turbulence on windy days so the plane tracks beautifully and feels more precise. Maybe you‘re a scratch builder who finds that scaling and CG limitations make it tough to create agile or realistic looking models that aren‘t a handful to fly. The AS3X System can help here too. What the AS3X System does not do is limit control or fly the airplane for you. You always have control. The AS3X System simply gives you more.

Upgrading Your Fleet with AS3X Technology

Adding the magic of AS3X technology to everything from small foamies to giant-scale warbirds is easy with these Spektrum™ AS3X receivers. All are compatible with DSM2® or DSMX® transmitters and are programmed using an intuitive interface that is available for PCs and popular mobile devices.
