Specially Tuned AS3X Receiver Makes 3D Easy The AS3X (Artificial Stabilization 3-aXis) technology in the models receiver makes it easy to discover the fun of 3D aerobatics without feeling frustrated. Using a unique combination of sensors and software it works behind the scenes to make slow-speed and knife-edge maneuvers feel incredibly stable without limiting the aircrafts agility or interfering with your control.
