KST Digital Servo

KST X12-508 HV Digital Coreless Servo Motor (metal gear)

The KST X12-508 HV Brushless servo offers a significantly longer life-span, with a superior power to weight ratio. The servo features a nicely machined aluminium case and offerers high voltage capability. It can be run directly from a 2S LiPo battery without the need for a separate voltage regulator.

Another great benefit of X12 servos is the all new design of a circuit board that generates no counter EMF in any working conditions. It eliminates any possible interference with your flybarless system or receiver unit thus as a result giving you only the best in-flight performance.

Due to the extreme reliability and performance this servos are used in film and motion picture industry as well as in robotics, drones, UAV, UAS, academic researches, and other highly demanding applications such as use in various military projects,..
