The GY401 is a high performance, compact, light weight AVCS (Angular Vector Control System) gyro developed for model helicopters. Conventional gyros send control signals to the rudder servo only when the tail of the helicopter moves. When the tail stops moving, the control signal from the gyro becomes zero. Conversely, the AVCS gyro continues to send control sig- nals to the servo even when the tail of the helicopter stops moving.
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
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.
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.
