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.
FEATURES: 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. One year warranty

SPECS: GY401 Gyro- S9254 Digital Servo Length: 1.1" (27mm) 1.6" (40mm) Width: 1.1" (27mm) .79" (20mm) Height: .79" (20mm) 1.4" (36.2mm) not including horn Weight: .95oz (27g) 1.8oz (50g) Torque: 47 oz-in Speed: .06 sec/60°
COMMENTS: 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 pulse. 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).
