Engineered for the absolute extremes of large-scale competition RC and heavy-duty industrial platforms, the KST SV6010-12 super high-voltage brushless digital servo unleashes a staggering 70 kgf.cm of stall torque and a rapid 0.09s/60° transit speed at 13V. Built with an oversized 8mm output spline, wear-free contactless magnetic (Hall effect) position sensing, and native 3S LiPo / 12V direct drive capability, the SV6010-12 delivers unyielding holding power, absolute zero-drift centering accuracy, and indestructible geartrain reliability for 1/5 and 1/8 scale RC vehicles, giant-scale aerobatic aircraft, and high-load robotics.

Key Features

• Monstrous 70 kgf.cm Stall Torque: Delivers massive holding and steering authority under the heaviest centrifugal loads, severe track bumps, and massive giant-scale aerodynamic surface pressures.
• Heavy-Duty 8mm Output Spline: Oversized 8mm spline architecture resists extreme torsional shear forces that strip conventional standard splines, paired with an included heavy-duty aluminum servo horn.
• Wear-Free Contactless Magnetic Sensor: Hall-effect contactless position sensing completely eliminates physical potentiometer wiper wear, resistive track degradation, and vibration noise for permanent, millimeter-precise centering repeatability.
• Super High-Voltage (SHV) Direct Drive: Wide 8.0V–13.0V operating range allows direct 3S LiPo connection — bypassing separate BEC voltage regulators, cutting system complexity, and maximizing voltage delivery.
• High-Efficiency Brushless DC Motor: Delivers cooler continuous operation, instantaneous torque delivery, and unmatched service life under punishing competition cycles.
• Expansive 200° Default Travel: Wide ±100° (200° total) factory travel range offers extensive linkage throw for giant-scale control surfaces, crawler steering setups, and robotic articulation (programmable endpoints).
• Hardened Steel Geartrain: Precision-cut steel gears supported by dual ball bearings withstand violent shock loads, landing impacts, and aggressive steering lock-stops without developing backlash.
• Full CNC Aluminum Casing: Precision-machined alloy case ensures rigid geartrain alignment and rapid thermal dissipation during grueling high-torque runs.
