About the WP173 Servo
High Performance
The WP173 servo offers exceptional performance with high torque and high-speed operation. At 6 volts, it delivers an operating speed of 0.09 seconds per 60°, while at 8.4 volts, the speed increases to an impressive 0.07 seconds per 60°. This rapid response time ensures precise control, making it ideal for competitive racing or complex maneuvers. With dynamic torque ranging from 123 ounces per inch at 6 volts to 173 ounces per inch at 8.4 volts, this servo is more than capable of handling the toughest tasks.
Durable Construction
Built to last, the WP173 features full metal gear ball bearings and a waterproof aluminum case, ensuring it can withstand harsh environments and heavy use. The all-metal gear train provides the strength needed to resist wear and tear, while the waterproof design protects the servo's internal components from moisture and dust. The addition of an aluminum servo horn further enhances its durability and reliability.
Wide Compatibility
Designed for versatility, the WP173 operates within a wide voltage range of 6 to 8.4 volts, making it compatible with a variety of RC models. Its twenty-five-tooth, five-millimeter diameter output shaft is standard, allowing for easy integration with most setups. Whether you're upgrading an existing model or starting to build one, this servo is an excellent choice for those requiring high performance in a compact size.
