Futaba GY Series Gyroscopes
Gyros FAQ - GY-601 Review by Model Helicopter World
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.

Here are the secrets behind GY Series gyros:

SMM (Silicon Micro Machine)
Essentially, it's micro-machining mechanical parts and systems right on a silicon chip a first in the hobby industry. This results in unprecedented levels of functionality, reliability and sophistication.

AVCS (Active Angular Velocity Control System)
This feature is the equivalent of heading hold, except that it utilizes a gyro sensor that's more accurate and less susceptible to vibration than conventional piezo gyros. It continually sends control signals to the servo , even when the tail is not moving, for extremely low temperature drift and more positive control for hovering and flying in crosswinds.

Ideal for electrics and 30-size machines

Single-gain adjustable trim, with 70Hz operation
