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 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.

Grate servos. I'm using them for 60" Extra and this time they will go for my new EF 60" Laser. Grate service from Hyperight, got them in less than two weeks. Thanks Neil for prompt and comprehensive answers to my questions.
