Upgraded from the acclaimed X12-508, the KST A12-610 V8.0 high-voltage mini wing servo brings more torque, refined soft-start protection, and premium CNC aluminum construction to glider wings and compact fixed-wing airframes. Delivering up to 9.0 kgf.cm at 8.4V in a slender 20g package, it provides the precision holding force and smooth control authority that competitive glider pilots demand — without adding unnecessary weight.
Key Features
- Upgraded Torque Performance: Delivers 8.0 kgf.cm at rated 7.4V and up to 9.0 kgf.cm at 8.4V — a significant step up from its predecessor, the X12-508.
- Soft Start Function: Built-in soft-start protection gently ramps servo movement on power-up, safeguarding linkages and control surfaces from sudden load spikes.
- High-Voltage Operation: Wide 4.8V–8.4V range supports direct 2S LiPo compatibility without voltage regulation.
- Coreless DC Motor: Fast, linear response with minimal deadband ensures precise aileron and flap control across the full travel range.
- Hardened Steel Geartrain: Precision metal gears engineered for zero backlash, consistent centering, and resilience against aerodynamic hinge loads.
- Full CNC Aluminum Casing: Precision-machined housing provides accurate servo bay fitment, structural rigidity, and effective heat dissipation.
