The KST X08 V6.0 Metal Gear Digital Micro Servo is a slim 8mm micro servo for RC gliders, DLG aircraft, and tight-space control installations. KST describes the X08 series as compatible with 1S and 2S LiPo-style setups, giving builders flexibility in compact aircraft power layouts. Verified KST data lists a DC 3.8V-8.4V voltage range, up to 2.80Kgf.cm torque at 8.4V, and 0.09sec/60deg speed at 8.4V. The servo uses a coreless DC motor, hardened steel gears, aluminum alloy case, potentiometer feedback, soft start, and programmable support. With a 23.5 x 8 x 16.8mm case and approximately 8g weight, X08 V6.0 is a strong choice when the installation needs a narrow digital servo without stepping up to a larger mini-servo size.

X08, X08H, and X08N are related X08-series products with different mounting layouts. Choose the version that matches the physical installation, not only the electrical specification. Does OpenELAB list multiple Shopify variants for this product? No. The current Shopify product is a single variant with SKU KST-X08-V60. What is the maximum listed torque? The technical specification lists up to 2.80Kgf.cm at 8.4V. What is the fastest listed speed? The fastest listed speed is 0.09sec/60deg at 8.4V. Is it programmable? Yes. KST lists programmable support and soft start for the X08 V6.0. What voltage range can it use? The listed voltage range is DC 3.8V-8.4V. What is included in the package? The package includes one X08 V6.0 micro servo, three plastic servo horns, four mounting screws, and one servo horn screw. What should I check before replacing another servo? Confirm the 23.5 x 8 x 16.8mm case, 15T 4mm spline, control pulse range, mounting style, and voltage before installation.
