Features
-Futaba's Entry Level Heading Hold Gyro + S9254 Servo
-Best choice for professional hobbyist.
-GY401 Gyro with SMM Technology from Futaba.
-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.
-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 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 (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.
