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 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.
