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 practically anywhere. But what really sets it apart is its specially tuned AS3X stabilization system. This exclusive technology makes it simple for sport pilots to discover the fun of hovering and harriers without compromising any of the dexterity an expert 3D pilot demands.

Specifically Tuned AS3X® Receiver Makes 3D Easy
The AS3X (Artificial Stabilization – 3-aXis) technology in the design’s receiver makes it simple to discover the fun of 3D aerobatics without feeling disappointed. Utilizing a unique combination of sensing units and software application, it works behind the scenes to make slow-speed and knife-edge maneuvers feel extremely stable without limiting the airplane’s dexterity or disrupting your control. The aircraft simply remains in whatever attitude you want without making you battle to keep it there.

The receiver likewise features five pre-programmed flight modes – 3 default modes that are active out of the box and two alternate modes you can activate later on. Each has different AS3X stability settings tailored for your ability level or the 3D maneuver you wish to try.

Default Modes
   General Flight Mode
     -Heading hold in roll-axis for a locked-in feel.

   Requirement AS3X Mode
     -Tuned for the professional 3D pilot but great for flying pattern aerobatics, too.

   Hover Assist Mode
     -Aggressive heading hold in roll, yaw and pitch so it's simpler to get in and maintain a hover. 

Alternate Modes 
   Knife-Edge Assist Mode
     -Heading hold settings for roll, yaw and pitch that make it simple to try knife-edge maneuvers.

   Torque Roll Assist Mode
     -Aggressive heading hold settings for yaw and pitch that make torque rolls simpler.

Flight-Ready Out of the Box
No assembly is required. The design includes the motor, Receiver/ESC and servos already set up. All you have to do is charge a battery, bind it to a suitable DSMX/DSM2® transmitter and fly. An E-flite® 150mAh 1S 3.7V 45C LiPo battery is recommended for best efficiency.*

Feather-Light, Carbon-Reinforced Airframe
Carbon fiber rods brace the wings so you can enjoy outstanding power-to-weight efficiency and still have the rigidity necessary for crisp control response. The design likewise features carbon fiber landing equipment with wheel pants.

Integrated Side Force Generators
Side Force Generators connected to the wing ideas enhance rudder authority in knife-edge flight so you can fly tighter knife-edge loops.

*Battery, transmitter and battery charger all sold independently.
