 GY Series Gyroscopes
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. |

FUTM0807 GY401
FUTM0808 GY401 Heli Gyro w/S9254
GY611 w/S9256
Adds a new dimension of control for larger-sized helis.
A super narrow pulse (760µs) drive system greatly improves servo response; high-speed processing boosts gyro response.
The high-resolution 12-bit Analog to Digital accurately converts the sensor output to a digital signal.
Newest generation SMM (Silicon Micro Machine) technology and a low-back aeroform case enhance vibration resistance and neutral characteristic.
The GY611's highly precise angular velocity sensor allows the AVCS to perform even better, minimizing rudder neutral position drift and eliminating the need to trim the rudder during flight.
Includes a high-response S9256 servo that's compatible with the super narrow pulse drive and features an alumite case with heat sink.
