This is the GY240 Gyro with SMM Technology from Futaba. 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. One Year Warranty
FEATURES: AVCS System: (Heading Hold) 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. SMM Gyro Sensor: Use of this newly developed technology virtually eliminates rudder trim changes during flight (see COMMENTS). Integrated, compact and lightweight design made possible by high density mounting technology. Conductive Resin Case: This case improves EMC (Electrostatic and electromagnetic interference) resistance.
