Engineered as the ultra-compact sibling to the legendary X10, the KST X10 Mini V8.0 high-voltage digital wing servo retains the class-defining 10mm slim profile while shaving weight down to just 23g with a shorter 29.6mm casing. Delivering an impressive 7.5 kgf.cm of torque and a blistering 0.10s/60° transit speed at 8.4V, the X10 Mini is purpose-built for outboard aileron bays, thin wingtips, and weight-critical F3F, F3B, F3J, and F5J competition sailplanes where minimizing rotational inertia and maximizing installation clearance are paramount.

Key Features

• Ultra-Compact 10mm Wing Profile: Retains the standard 10mm thickness while shortening body height to 29.6mm and dropping weight to 23g — ideal for narrow outboard wing bays and thin airfoils where full-size wing servos struggle to fit.
• Reduced Wingtip Inertia: A 5g savings per servo over the standard X10 significantly reduces roll inertia at the wingtips, enhancing roll rates and thermal handling agility.
• High-Voltage Operation: Native 4.8V–8.4V range supports direct 2S LiPo receiver packs — eliminating bulky voltage regulators, simplifying wiring harnesses, and ensuring peak voltage delivery.
• Smooth Coreless DC Motor: Delivers instant start-up, ultra-smooth linear travel, and crisp centering precision with an ultra-narrow 2μs deadband.
• Hardened Steel Geartrain: Precision-cut steel gears supported by dual ball bearings resist slop and withstand repeated high-speed aerodynamic hinge loads and rough slope landings.
• Full CNC Aluminum Casing: Precision-machined alloy case ensures perfect servo frame/IDS fitment, rigid geartrain alignment, and rapid thermal dissipation.
• Programmable & Soft Start: Configurable travel limits and soft-start protection to safeguard linkages and control horn mounts on power-up.
• LDS / IDS Compatible: Directly compatible with standard Integrated Drive System (IDS) and bearing frame mounts for completely flush aerodynamic installations.
