Using a unique mix of sensors and software application, it works behind the scenes to make slow-speed and knife-edge maneuvers feel incredibly steady without limiting the aircraft’s dexterity or disrupting your control. The plane simply stays in whatever mindset you desire without making you struggle to keep it there.

The receiver likewise includes five pre-programmed flight modes – three default modes that are active out of package and two alternate modes you can trigger later on. Each has different AS3X stability settings customized for your skill level or the 3D maneuver you want to try.
