Revolutionary gyro technology: 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 Electro Mechanical 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 its available today from Futaba.
