Futaba GY401 is a High Performance, Compact and Light Weight (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 helicopter attitudes change and are automatically canceled; tail (rudder) operation is easy, making it perfect for 3D flight.
• 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. Integrated, compact and lightweight design made possible by high density mounting technology.
• Conductive Resin Case: This case improves EMC (Electrostatic and electromagnetic interference) resistance.

Includes:

• One GY401 gyro
• One mini plastic adjustment screwdriver
• Three mounting pads
• One instruction sheet

Specifications:

• Length: 27mm; Width: 27mm; Height: 20mm
• Weight: 27g

Comments:

Can be used in helicopters and airplanes (Due to 0-100% Gain Adjust). The new SMM (Silicone 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 anunprecedented level of functionality, reliability, and sophistication. This will not work with the JR digital servos. These have a different pulse.
