The NEW Carbon-Z ™ Yak 54 Forget what you thought you knew about electric aircraft construction and performance. The new Carbon-Z Yak 54 is a giant leap in both that takes Bind-N-Fly ® aircraft capabilities to a whole new level. Knife edge loops, hovering torque rolls at half throttle, ballistic uplines – no longer is this kind of performance the privilege of a select few with the time and money to build large-scale 3D airplanes. The Bind-N-Fly Carbon-Z Yak 54 lets you experience the same precision and unlimited performance in the time it takes to charge a battery, for a fraction of the price. It’s all made possible by Carbon-Z construction. Developed by world aerobatic champion Quique Somenzini, Carbon-Z uses a patent-pending technique to fuse the lightweight durability of a molded Z-Foam™ structure with the strength and rigidity of carbon ﬁber. The result is an airframe that is as strong as or stronger than balsa with an exterior that looks great in all temperatures and weather. This advanced airframe, combined with the custom brushless power system Quique developed for it, gives the Carbon-Z Yak 54 a stunning thrust-to-weight ratio of 2:1 and 3D performance that knows no limits.

Endless possibilities. RealFlight G5.5 isn’t just an essential ﬂight training tool. It’s the R/C ﬂight sim with the most advanced ﬂight physics for mastering your skills. RealFlight takes the risk out of learning how to ﬂy, allowing you to adjust heli parameters to match your actual machine. You can even add changing weather conditions and turbulence levels. Apply tail rotor failures, and you can practice what to do in a real emergency. Other ﬂight sims aren’t as realistic as RealFlight G5.5, but that’s why they aren’t called RealFlight.
2010 INNOVATION OF THE YEAR
The most realistic recreation of R/C ﬂight ever!
