With a flying weight of hardly over an ounce (36 grams), the compact UMX™ Yak 54 3D ultra-micro is little adequate and light adequate to be flown practically anywhere. But exactly what truly sets it apart is its specifically tuned AS3X stabilization system. This special innovation makes it simple for sport pilots to discover the fun of hovering and harriers without sacrificing any of the dexterity an expert 3D pilot demands.

Specifically Tuned AS3X® Receiver Makes 3D Easy
The AS3X (Artificial Stabilization – 3-aXis) innovation in the design’s receiver makes it simple to discover the fun of 3D aerobatics without feeling annoyed. Utilizing a unique combination of sensing units and software, it works behind the scenes to make slow-speed and knife-edge maneuvers feel incredibly stable without restricting the aircraft’s dexterity or disrupting your control. The aircraft merely remains in whatever mindset you desire without making you struggle to keep it there.

The receiver also includes 5 pre-programmed flight modes – 3 default modes that are active out of the box and 2 alternate modes you can trigger later. Each has different AS3X stability settings customized for your skill level or the 3D maneuver you want to attempt.

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

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

   Hover Assist Mode
     -Aggressive heading hold in roll, yaw and pitch so it's much easier 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 attempt knife-edge maneuvers.

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

Flight-Ready Out of package
No assembly is required. The design includes the motor, Receiver/ESC and servos already set up. All you need to do is charge a battery, bind it to a suitable DSMX/DSM2® transmitter and fly. An E-flite® 150mAh 1ST 3.7V 45C LiPo battery is suggested 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 rigidness needed for crisp control response. The design also includes carbon fiber landing gear with wheel trousers.

Integrated Side Force Generators
Side Force Generators attached to the wing pointers boost rudder authority in knife-edge flight so you can fly tighter knife-edge loops.

*Battery, transmitter and charger all offered individually.
