This is the Futaba GY401 Gyro with an S9254 Digital Servo.|
This is a high performance, compact and lightweight
(AVCS) Angular Vector Control System gyro developed for model helicopters.
Because the sensor and control circuit are integrated, it is simple to install.
AVCS System: Since the rudder trim changes (caused by wind and other
meteorological changes) the front, rear, and other heli attitudes
change and are automatically cancelled; tail (rudder) operation is
easy, making it perfect for 3D flight.
(also known as heading hold gyro)
SMM Gyro Sensor: Use of this newly developed technology virtually
eliminates rudder trim changes during flight (see COMMENTS).
Digital Servo Compatible (DS Mode): DS mode makes it compatible with
Futaba Digital Servos. This maximizes the high-speed response
performance of the Digital Servo.
Included high-speed S9254 Digital Servo boasts 47 oz-in torque and a
speed of .06 sec/60°
Remote Gain Function and Mode Switching Function Remote: Gain
function allows sensitivity switching from the transmitter and mode
switching function allows AVCS/normal gyro mode switching.
Integrated, compact and lightweight design made possible by high
density mounting technology.
Conductive Resin Case: This case improves EMC (Electrostatic and
electromagnetic interference) resistance.

Can be used in helicopters and airplanes (Due to 0-100% Gain Adjust).
The new SMM (Silicon 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
Voltage- use only with a 4.8V battery. (if you use it with a
higher voltage battery it needs to be regulated to 5.2V).
