The KST A12-T is an ultra high torque servo that uses a magnetic (hall effect) sensor to provide position feedback, replacing the troublesome sliding contact potentiometer used in most sevos. This improves the reliability of the servo enormously, while also proviing better accuracy and resolution. The A12-T also benefits from an ultra-efficient 7 phase coreless motor, a hardened steel gear train, aluminum case, slow start, low current consumption and constant power output. These make it perfect for high performance gliders, larger electric models and jets.

This servo uses a mini 25 tooth (Futaba) output spline for maximum compatibility with the large variety of aftermarket control horns. Supplied accessories include two strong red nylon output arms, and three normal strength white nylon output arms.
