About this part

Servo Overview:

The KST A12-T Aluminum Mini Coreless Magnetic Sensor Metal Gear High Voltage Servo is a precision-engineered solution for large-scale gliders, open-class GPS gliders, large aerobatic gliders, and jet turbine models. Built for high-voltage (HV) operation, it combines advanced technology with robust construction to deliver outstanding control and reliability in demanding applications. Featuring a mini twenty-five tooth Futaba-compatible output spline, it ensures maximum compatibility with a wide range of aftermarket control horns.

About the Metal Gear HV Servo


Superior Reliability

Instead of a traditional sliding contact potentiometer, the KST A12-T uses a magnetic Hall effect sensor for position feedback, dramatically improving durability and eliminating common wear-related failures. This design also enhances accuracy and resolution for precise control inputs. An ultra-efficient coreless motor provides smooth, consistent power output, while the hardened steel gear train ensures long-lasting strength. The aluminum case offers excellent heat dissipation and secure mounting, and features such as slow start, low current consumption, and constant power output make this servo an exceptional choice for high-performance aircraft.
