With a flying weight of barely over an ounce (36 grams), the compact UMX™ Yak 54 3D ultra micro is small enough and light enough to be flown just about anywhere. But what really sets it apart is its specially tuned AS3X stabilization system. This exclusive technology makes it easy for sport pilots to discover the fun of hovering and harriers without sacrificing any of the agility an expert 3D pilot demands.
Specially Tuned AS3X® Receiver Makes 3D Easy The AS3X (Artificial Stabilization – 3-aXis) technology in the model’s 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 manoeuvres feel incredibly stable without limiting the aircraft’s agility or interfering with your control. The plane simply stays in whatever attitude you want without making you struggle to keep it there.
The receiver also features five pre-programmed flight modes – three default modes that are active out of the box and two alternate modes you can activate later. Each has different AS3X stability settings tailored for your skill level or the 3D manoeuvre you want to try.Default Modes
Standard AS3X Mode Tuned for the expert 3D pilot but great for flying pattern aerobatics, too.
Hover Assist Mode Aggressive heading hold in roll, yaw and pitch so it's easier to enter and maintain a hover.
Torque Roll Assist Mode Aggressive heading hold settings for yaw and pitch that make torque rolls easier.

Feather-Light, Carbon-Reinforced Airframe Carbon fibre rods brace the wings so you can enjoy outstanding power-to-weight performance and still have the rigidity necessary for crisp control response. The model also features carbon fibre landing gear with wheel pants.
Built-In Side Force Generators Side Force Generators attached to the wing tips boost rudder authority in knife-edge flight so you can fly tighter knife-edge loops.
