With a flying weight of barely over an ounce (36 grams), the compact UMX™ Yak 54 3D ultra-micro is small sufficient and light sufficient to be flown almost anywhere. But exactly what really sets it apart is its specifically tuned AS3X stabilization system. This exclusive innovation makes it simple for sport pilots to find the fun of hovering and harriers without compromising any of the dexterity a specialist 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 find the fun of 3D aerobatics without feeling frustrated. Utilizing a unique mix of sensors and software application, it works behind the scenes to make slow-speed and knife-edge maneuvers feel incredibly stable without limiting the airplane’s dexterity or hindering your control. The plane simply stays in whatever attitude you want without making you battle to keep it there.

The receiver also includes 5 pre-programmed flight modes – 3 default modes that are active from package and two alternate modes you can trigger later. Each has various AS3X stability settings tailored 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 specialist 3D pilot but great for flying pattern aerobatics, too.

   Hover Assist Mode
     -Aggressive heading hold in roll, yaw and pitch so it's much easier to go into and preserve 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 From package
No assembly is required. The design features the motor, Receiver/ESC and servos already set up. All you need to do is charge a battery, bind it to a compatible DSMX/DSM2® transmitter and fly. An E-flite® 150mAh ONE 3.7V 45C LiPo battery is advised for finest performance.*

Feather-Light, Carbon-Reinforced Airframe
Carbon fiber rods brace the wings so you can delight in exceptional power-to-weight performance and still have the rigidity needed for crisp control action. The design also includes carbon fiber landing gear with wheel pants.

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

*Battery, transmitter and charger all offered separately.
