Nautical Power ControlHeavy Duty Winch For RC Sailboats
The Hitec HS-785HB Giant Scale Analog Karbonite Gear Sail Winch Servo delivers powerful torque and precision for large scale RC sailboats. Equipped with a large drum wheel providing 3.5 full revolutions of travel, this high-performance sail winch servo easily controls large sail setups. Dual ball bearings ensure smooth output shaft rotation and long-lasting durability on the water.
Command The WindReliable Torque For Large Scale Model Yachts
Engineered specifically for nautical modeling enthusiasts, the Hitec HS-785HB Giant Scale Analog Karbonite Gear Sail Winch Servo offers the extreme rotation and pulling force needed for big rig sailboats. Its heavy-duty Karbonite gear train is four times stronger than standard white nylon gears, preventing slop and gear stripping under heavy wind pressure. Supported by dual ball bearings on the output shaft, the Hitec HS-785HB delivers smooth and accurate sail adjustment for popular models such as the Pro Boat Ragazza. Important Note: Never use liquid thread lockers on Karbonite gears as the chemical compound causes the plastic output shaft to fail.

Frequently Asked QuestionsEverything you need to know
What is the rotational travel range of the Hitec HS-785HB Giant Scale Sail Winch Servo?
The Hitec HS-785HB Giant Scale Sail Winch Servo features a wide 3.5 full revolutions (1260 degrees) of drum rotation, allowing it to easily pull in and release large sail rigging on scale model yachts.
Can I use chemical thread locker on the Hitec HS-785HB Sail Winch Servo?
No, you should never use thread lockers (such as Loctite) on any Karbonite geared servo. Thread locking compounds chemically degrade Karbonite plastic, causing output shaft failure.
Is the Hitec HS-785HB Sail Winch Servo compatible with the Pro Boat Ragazza?
Yes, the Hitec HS-785HB Sail Winch Servo is an ideal replacement sail winch servo for the Pro Boat Ragazza and other giant scale RC sailboats.
