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

I am new to KST, I am a Hitec user so far..however I am so impressed with the quality & performance for the price point they exceed my expectations & I have bought stocks for the next few aircraft projects..Impressed with Neil too, good advice & prompt no nonsense delivery..on the doorstep before you would think possible these days.

I use these in the fuselages of my aerobatic models for elevator and rudder. Excellent power, precision and speed. I intend to try one as a steering servo in a 12th scale racing car when we get back to normal life.
