Thank you for purchasing the E-fl ite ® UMX ™ Yak 54 180 ultra micro airplane with which you’ll enjoy a
bold new level of aerobatic performance. No other aerobatic design meets the challenge and demands of
precision and 3D versatility like the Yak 54 can. Recognized early on by the father of 3D, Quique Somenzini,
his Yak 54 concept ushered in a new era of RC aerobatic agility that’s now possible to experience in small
fl ying spaces indoors and out. Your UMX Yak 54 180 offers incredible speed and thrust from its specially
tuned brushless power system. But what truly makes this go-anywhere 3D thoroughbred truly special is
its incredible AS3X
® System that delivers incredible precision so that you can perform aerobatics smoothly
and the control authority to pop sharply into 3D maneuvers with the stability of a giant-scale aerobat. And
despite its size, AS3X stability also helps you fl y in moderate winds without seeing so much as a bobble,
plus you’ll be able to hold high-alpha fl ight angles that have a locked-in feel.
The exceptional capabilities of the E-fl ite UMX Yak 54 180 may require a little more fi rst-fl ight preparation
than other Bind-N-Fly
® ultra micro aircraft you may have experienced. A thorough read of this manual will
help assure that you’re equipped to successfully enjoy all the benefi ts this outstanding ultra micro model
has to offer.
