About this part
Servo Overview:
The KST A12-S Aluminum Mini Coreless Magnetic Sensor Metal Gear High Voltage Servo is purpose-built for large-scale gliders, open-class GPS gliders, large aerobatic gliders, and jet turbine models. This servo shares the same length as the popular KST X10 servo, but features a slightly thicker twelve-millimeter profile for added strength and stability. Equipped with a twenty-five tooth spline compatible with Futaba standards, this servo delivers precise and reliable control for a variety of demanding applications.
