HS-785HB Giant Scale Analog Karbonite Gear Sail Winch Servo (HRC33785S)

This giant-scale analog sail winch servo powers the winch on large RC sailboats, delivering the torque and travel needed to reel in big sails with precise control. With a large drum wheel and about three-and-a-half revolutions of travel, it can haul in sails on even the largest rigs with steady, predictable motion.

Built around a dual-ball-bearing supported output shaft and Karbonite gears, this winch servo is designed for long, reliable service. It’s a ready replacement option for the Pro Boat Ragazza, offering robust performance for demanding conditions; note that thread lockers should not be used on Karbonite-geared servos to avoid shaft damage.
