Description
The Hitec HS-765HB is a specialized, high-performance sail control servo engineered specifically for the demanding environment of competitive and recreational RC sailing. Featuring Hitec’s proprietary Karbonite gear train, this servo offers a remarkable balance of strength and wear resistance, significantly outperforming standard plastic gears. With a robust torque rating of up to 13.2kg-cm, it provides the sustained pulling power required to adjust sails precisely, even under heavy wind loads.
Designed for reliability in marine settings, the HS-765HB includes a water and dust-resistant case, ensuring that internal electronics are protected from moisture and salt air. It utilizes a dual ball-bearing output shaft and a high-efficiency 3-pole ferrite motor to deliver smooth, consistent actuation throughout its 140° range of movement. Whether you are navigating an RC sailboat in light breezes or competitive heavy-air conditions, this servo provides the precision and durability necessary to keep your vessel performing at its peak.
