This is a Futaba GY401 Gyro w/SMM Technology! use of a new extremely small drift SMM(Silicon Micro Machine) gyro sensor virtually eliminates rudder trim changes during flight. Since rudder trim changes caused by changes in tail reaction, torque changes due to wind and other meteorological changes and main rotor rotation variations are automatically cancelled, tail (rudder) operation is very easy, making it perfect for beginners.
It's a ground-breaking Futaba innovation, resulting in a line of helicopter gyros like nothing you've ever seen. The new GY series feature several high-tech advantages over conventional piezo engineering that make R/C helicopter flying even more stable and reliable.
This is the Futaba GY401 Gyro. 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: Sine the rudder trim changes (caused by wind and other meteorological changes) the front, rear, and other heli attitudes change and are automatically canceled; 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.
