Micro-machining mechanical parts and systems right on a silicone chip and also low-back aeroform case improves vibration resistance and neutral characteristic. AVCS (Angular Vector Control System) (same as Heading Hold) system requires a high-precision angular velocity detection function and extremely small output drift by using a new type of gyro sensor. This minimizes rudder neutral position drift during flight and eliminates the need to trim the rudder during flight.
