The new KST DS589MG is a high-voltage servo suitable for helicopter cyclic and all fixed-wing applications. At 15mm thick and 40g weight, it is reasonably small and light, considering its excellent 9.2 Kgf.cm of torque and 0.08 sec/60° speed. A similar size and torque as the well regared MKS HV737 and is faster and better value.

This servo uses a contactless sensor for position feedback. Also, see the KST MS589 servo which is the same size but uses a magnetic position sensor.

Features
