This is the GY401 Gyro with SMM Technology

This is a High Performance, Compact and Lightweight (AVCS) Angular Vector Control System gyro developed for model helicoptersBecause 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.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.Conductive Resin Case:This case improves EMC (Electrostatic and electromagnetic interference) resistanceIntegrated, compact and lightweight design made possible by high density mounting technologyNever opened and the box is 100% new.

Specification: Length: 27mmWidth: 27mmHeight: 20mmWeight: 27gVoltage- use only with a 4.8V battery. (if you use it with a higher voltage battery it needs to be regulated to 6V)
