GY GYROS

For better-than-piezo gyro performance!

Unlike standard piezo gyros with only a few sensor

nodes, GY Gyros feature a cluster of 18 sensor nodes.

It’s a big difference in sensor

numbers that accounts for

GY’s amazing improvements

in sensitivity and accuracy.

While leaders in other

industries were starting to explore the

potential of Silicon Micro Machining

(SMM), Futaba had already created the

first practical application: GY Series Gyros

for radio control. SMM allows mechanical

and electronic components to be mounted

onto a machined, high-density chip that’s

smaller than a pencil point. The result is a

resonator that is shock- and vibration-

resistant, far more sensitive and accurate

than standard piezo gyros and directly

responsible for GY gyros’ dramatically

superior and exceptionally reliable

performance.

• Avoids the temperature sensitivity of

piezo crystals — GY Gyros function well

within a wide 14°F to 122°F range!

• Reduces start-up time to a virtually

instantaneous 3 seconds

• Requires just 80mA of operating current

Only SMM technology could create GY

Gyros’ incredibly compact, lightweight

Active Angular Velocity Control System

• Sends control signals to the gyro servo continuously, even

when the tail is not moving

• Trims the rudder against side winds automatically, virtually

eliminating the need for rudder trim changes during flight

• Provides the most positive control for hovering and flying

in crosswinds

• Competition gyro ideal

for F3C pattern fliers

• Ultra high-speed

330Hz operation

• Gain can be adjusted

from transmitter

• LCD screen allows

precise setting
