Futaba GY 401 Gyro

Delivers high performance for 30- to 60-size helis


Has remote gain feature and transmitter-controled switching to AVCS


Operation is almost 4 times faster (270Hz) than conventional gyros


Measures 1" x 1" x 0.8" (27 x 27 x 20 mm), and weighs 0.95 oz (27 g)

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.

          The new SMM (Silicone Micro Machine) technology is the integration
            of mechanical elements, sensors, actuators and electronics all
            brought together on a common substrate chip. This hobby industry
            first, results in a gyro sensor with an unprecedented level of
            functionality, reliability, and sophistication.
          This will not work with JR digital servos. These have a different
            pulse.

JR G770 Gyro
