KST DS589MG Servo – 9.2Kg.cm 0.08s 40.0g 15mm

The new KST DS589MG is a very powerful high voltage contactless servo suitable for helicopter cyclic and all fixed wing aplications. At 15 mm thick and 43 g weight it is reasonably small and light, considering its excellent 9.2 kg.cm of torque and 0.08 sec/60° speed.

The KST DS589MG a similar size and torque as the well regared MKS HV737 and is faster and better value.

This servo uses a potentiometer for positon feedback. Also see the KST M589 servo which is the same size but uses a magnetic position sensor.
