Revolutionary Gyro Technology
It's ground-breaking Futaba innovation, resulting in a line of heli gyros like nothing you've ever seen. The new GY series feature several high-tech advantages over conventional piezo engineering that make R/C heli flying even more stable and reliable.
 
Introducing the GY520. The smallest, lightest and most advanced gyro in the world.

GY Series technology revolutionized gyro performance in 2000 -- and the GY520 is doing it again today. Its cutting-edge MEMS (Micro ElectroMechanical System) sensor design, ultra high-speed processing speed and advanced PID control algorithm put it a quantum leap ahead of all other heading hold gyros in size, weight and performance. It's the gyro of tomorrow -- and it's available today from Futaba.
 
Offers premium performance at a surprisingly affordable price.
Weighs just 6.9 g -- a full 9 g less than any other heli heading hold gyro!
Exceptionally compact, for fast, easy installation in helis ranging from electric micros to .91 glow 3D Monsters!
Cutting-edge MEMS (Micro ElectroMechanical System) sensors detect smaller angle deviations than any other technology.
Improved, ultra high-speed processing rates and an 800° /second rate range offer faster, smoother response and consistent pirouette rates.
Delivers superior performance with analog servos -- and excels with digitals!
