Standard Waterproof Plastic Gear Servo 25T (SPMS663)

Standard Waterproof Plastic-Gear Servo with a 25-Tooth Spline is a compact, weatherproof actuator designed for RC models that need reliable, precise control in damp or exposed conditions. It’s a versatile choice for steering, throttle, and other control tasks in boats, cars, and similar hobby builds.

Built with a plastic case and nylon gear train, this digital servo offers durable, smooth operation. It delivers about 76 oz-in of torque at 6V and travels roughly 0.20 seconds per 60 degrees, powered by a 6.0–7.4V supply. The unit measures about 1.57 inches long, 0.78 inches wide, and 1.48 inches tall, and uses a standard 25-tooth spline compatible with common servo horns and linkages.
