MS589 is a very powerful high-voltage contactless servo suitable for helicopter cyclic and all fixed wing applications. At 15mm thick and 38g weight it is reasonably small and light, considering its excellent 9.2Kgf.cm of torque and 0.08 sec/60° speed.
The MS589 uses a Hall effect (magnetic) position sensor for maximum accuracy and reliability. Also, see the KST D589MG servo which is the same size but uses a potentiometer as a position sensor.
The KST MS589 has a similar size and torque as the well-regarded MKS HV737 and is faster and better value.
Despite not having an -MG moniker the KST MS589 servo has a hardened steel metal gear train.
