UMX Yak 54 3D BNF Basic with AS3X, 430mm Overview
With a flying weight of barely over an ounce (36 grams), the compact UMXâą 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 AS3XÂź 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 AS3XÂź Receiver Makes 3D Easy
The AS3XÂź (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 maneuvers 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 AS3XÂź stability settings tailored for your skill level or the 3D maneuver you want to try.
Default Modes
Standard AS3XÂź Mode
Hover Assist Mode
Alternate Modes
Torque Roll Assist Mode
Flight-Ready Out of the Box
No assembly is required. The model comes with the motor, Receiver/ESC and servos already installed. All you have to do is charge a battery, bind it to a compatible DSMX/DSM2Âź transmitter and fly. An E-fliteÂź 150mAh 1S 3.7V 45C LiPo battery is recommended for best performance.*
Feather-Light, Carbon-Reinforced Airframe
Carbon fiber 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 fiber 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.
*Battery, transmitter and charger all sold separately.
