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.

Nice Value
Color: Consuela the Cactus - Large, Size: Large Dog
Very cute! Its soft and feels like it is well made. It is a heavier toy and a tougher one. Not a plush toy. I will order again for our older dogs. Nice value for sure!

Great toy for our best boys!
Color: Consuela the Cactus - Large, Size: Large Dog
You can never go wrong with BarkBox toys and this was no exception. Our dogs like toys that have squeakers and that they can tear into. This style of toy fits the bill. The design is cute as well. I’ve had this in the house for months and, while it’s definitely seen better days, it’s still intact and they haven’t gotten to the inner layer. (Not for want of trying.) The perfect type of toy for our fur babies.

Survives 7 months so far.
Color: Christmas Consuela, Size: Large Dog
It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks. Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

Short-lived but much enjoyed as a chew toy
Color: Consuela the Cactus - Large, Size: Large Dog
I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.
