Description

The KST X08H is a version of the KST X08 servo with horizontal mounting lugs (also called mounting tabs), making it suitable for use in wing and other flying surfaces. It is especially good for ailerons on DLGs, electric racers, and all models with thin flying surfaces. The gearing has been optimised to improve the torque while keeping an excellent speed. The X08-H can be operated from a voltage as low as 3.8V (1S LiPo) or as high as 8.4V (2S LiPo). KST improved its geartrain machining tolerances, and this servo is completely slop free, and equal to products costing twice as much. Despite not having an -MG moniker this servo has metal gears, and is very tough.

The KST X08H's high torque, good speed, and 8mm thinness make it suitable for many high performance glider, pylon racers and EDF applications. With up to 2.8kg.cm torque the KST X08 is appropriate for F3K, F5D, F5J, many types of high performance models.

Feb 2017: We are now only selling the new V5 version (there wasn't a V4) which has improved firmware and electronics, giving even more precise centering and a greater throw.

The extreme reliability and performance of these servos also makes them very suitable for use in film and motion picture industry special effect departments. They are also used in robotic, drone, UAV, UAS, academic research, military, and other highly demanding applications.

KST X08H

These are terrific servos, very small and light, but also surprisingly powerful in the high voltage version. I have been using them for all surfaces in a Snipe, and for ailerons in my Ultima 2 Standard. They reduce the outboard weight on the U2 and are able to handle the loads imposed by this airframe without blowback. I bring the ailerons down with flaps, but not as much throw, for descent preset and also for landing. I am pleased with these servos and with Neil's prompt service and shipping.

I like these servos because "They Work".... I recently switched over to HV type servos and these seem to have the power and centering we need.
I like the service I get from Neil and his packaging and shipping is very good.

KST Servos for a Mini Q

I used these expensive servos in my Mini Q as I did not wish to "Spoil the ship for a halfpenny worth of tar" so to speak, they have proved to be ideal for the Mini Q racer. The service from Hyperflight is excellent.

No Brainer

I have KST 08's in all my F5B models, I think they are an excellent product/weight/performace package. As to where to get them, Hyperflight equally a no brainer.
