Description
The Hitec HS-785HB is the industry-standard sail winch servo engineered to deliver the extended travel and reliable pulling power required for demanding RC sailboat and maritime applications. Featuring a massive 3.5 revolutions (3.5 turns) of travel, this winch is specifically designed to handle large sail configurations with precision and ease. Its output shaft is supported by dual ball bearings, ensuring smooth, low-friction operation that maintains accuracy under the continuous, high-tension loads typical of competitive sailing.
Constructed with Hitec’s durable Karbonite gear train, the HS-785HB provides a rugged, shock-resistant alternative to traditional plastic gears, guaranteeing longevity in harsh marine environments. The unit is housed in a water and dust-resistant case, protecting internal electronics from the salt air and moisture inevitable at the water’s edge. Whether you are outfitting a large-scale racing sloop or a complex winch-based automation project, the HS-785HB offers the robust performance and specialized travel range that standard servos simply cannot match.

Key Features
- Extended 3.5-Turn Travel: The integrated large-diameter drum wheel provides over three full revolutions of rotation, perfectly suited for hauling in large-scale sail sheets.
- Durable Karbonite Gearing: Proprietary gear material offers superior strength and wear resistance compared to standard plastic, ensuring long-term mechanical reliability.
- Dual Ball Bearing Output: Industrial-grade ball bearings support the output shaft, reducing mechanical drag and ensuring consistent rotation under heavy winch loads.
- Water & Dust-Resistant Housing: Specifically sealed to protect internal components from moisture, salt spray, and debris in harsh marine or outdoor environments.
- Reliable High Torque: Delivers consistent, high-torque pull necessary to manage sail tension effectively even in gusty wind conditions.
Benefits
- Maximum Control Range: The 3.5-turn capacity allows for precise, wide-range sail trim adjustments, essential for optimizing boat speed and heading.
- Exceptional Reliability: The combination of Karbonite gears and ball bearings minimizes the risk of gear failure or output shaft wobble during high-intensity use.
- All-Weather Capability: Robust sealing ensures the winch continues to operate reliably even when subjected to the splashing and humidity common in RC sailing.
- Smooth Mechanical Operation: Reduced friction from the ball-bearing output ensures that winch movements are fluid, preventing jerky sail behavior that could affect boat handling.
- Standardized Marine Integration: Designed for easy installation in most standard RC sailboat winch bays, making it a perfect drop-in upgrade or replacement part.
Applications
- RC Sailboat Winch Systems: The definitive choice for controlling main and jib sheets in competitive and recreational remote-controlled sailboats.
- Large-Scale Winch Automation: Excellent for custom automation projects requiring multiple rotations of high-torque, reliable cable pulling.
- Heavy-Lift Cable Mechanisms: Suitable for experimental RC projects that require a winch-based system to lift or pull significant loads.
- Animatronic Tension Systems: Can be used to manage cable-driven motion in animatronic figures requiring extended, high-torque range-of-motion.
- Industrial Research Prototypes: Used in labs for testing mechanical tensioning and pulley systems in a controlled RC-compatible form factor.
