Buy the KST X08N V6.0 compact servo drive for your FPV drone and miniature machinery!
Ensure precise control of actuators under severe weight constraints. The KST X08N V6.0 servo drive is a high-performance solution for aircraft modeling and drone manufacturing. With an ultra-thin design of just 8 mm thick and a weight of 8 grams, this servo drive easily integrates into the most compact designs where every second and every gram counts.
A wide range of operating voltages from 3.8V to 8.4V allows it to be used with various types of batteries.
-
Premium Coreless motor. Highly efficient coreless motor provides fast response, smooth running and minimal energy loss compared to traditional brushed motors.
-
Wide HV range. Operates at voltages from 3.8V to 8.4V, which allows it to be used with both 1S and 2S LiPo batteries without additional stabilizers.
-
High torque. Develops force up to 2.8 kg/cm at a voltage of 8.4V for confident control of mechanisms.
-
Lightning speed. Just 0.09 seconds per 60 degrees at 8.4V guarantees instant response to commands.
-
Maximum reliability. Solid steel gears and dual precision ball bearings ensure durability and minimal backlash even under intense loads.
Operating principle and design features
KST X08N V6.0 is a digital HV micro servo drive based on advanced coreless motor technology. Unlike traditional iron-core motors, a coreless motor has significantly lower rotor inertia. This allows it to accelerate and decelerate almost instantly, providing exceptional positioning accuracy and fast response to commands. Digital technology guarantees higher angular resolution and more precise position holding compared to analogue servos .
The durable, CNC-machined aluminum alloy body not only provides rigidity, but also effectively dissipates heat from the motor and electronics, maintaining stable performance over long periods of use.
The hardened steel gearbox with two precision ball bearings minimizes backlash and guarantees durability even under heavy-duty conditions. Model V6.0 supports programming via KST-Tool #1/#5, allowing you to customize end points, center and direction of rotation for perfect installation.

This servo is ideal for use in FPV drones as a drive for load drop systems and micro-gimbal rotation mechanisms, as well as for DLG, F3K, F5K gliders and other miniature aircraft models. Version V6.0 received an improved set of gears to minimize backlash. Its programmability, high precision and ultra-light weight make it an excellent choice for projects where every gram and fraction of a second matters.
