Super narrow pulse drive system substantially improves servo response. Microcomputer high-speed arithmetic processing substantially improves gyro response. High-resolution 12-bit A/D (Analog to Digital) accurately converts sensor output to a digital signal. SMM (Silicone Micro Machining) 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.

Futaba S9256 digital servo is fully compatible with super narrow pulse drive and features high response (0.06 sec/60°) and Alumite case with heat sink to cool the motor.

You get: Futaba GY611 sensor, control amp, S9256 servo, mini screwdriver, 3 sections double sided tape and instruction sheet

You’ll need: 4.8V Rx battery (higher voltage could damage the servo) or a regulated 6V system with a separate voltage regulator (5.3v max) for the servo.
