Ecopower 110S Servo Banner Photo

The EcoPower WP110S Cored Waterproof "High Speed" Metal Gear Digital Servo is a great option if you are looking for an affordable, waterproof RTR servo upgrade. This high speed version of the EcoPower WP110T cranks out 280 oz-in of torque at 7.4V, with 0.09sec/60°! This makes it a great choice for 1/10 bashing, 1/10 racing, RC boat and even RC airplane applications. Lifetime Gear Warranty through Amain Hobbies for added confidence and durability.

The WP110S is waterproof up to 1-meter so driving in the rain, puddles, snow and mud are not an issue. With .09 transit speed at 7.4V, the WP110S is fast enough to make is a good choice for steering, aileron control and much more! Metal gears were used to create a durable gear train that is easily serviced, and the plastic case with aluminum center section keeps the servo running cool while remaining lightweight. Plus, the digital circuitry allows compatibility with vehicles that use traction control/gyro systems, making the WP110S a viable option for models that are equipped with a stability system.

Good servo for the money. Using this as a throttle servo on my Mugen MBX8R. 4 stars because it doesn't always center perfect but on the track as a throttle servo I can't really notice a problem. Edit: second time out using it, it started smoking and stopped working. Appears to have shorted out and caught fire. Edit 2: Amain took care of me quickly and the warranty was great. If the second servo works better I'll update my review as flukes can happen with anything. Hopefully my smokey servo was just a one off. Edit 3: replacement servo appears to be working well.

This servo worked great on my fury 223s! Plenty of speed and power and comes with a lot of servo horns, would highly recommend

Jim Brockmanon EcoPower WP110S Waterproof High Speed Metal Gear Servo

Bought 3 2 work well as they should. One won’t center every time

Jim CampbellVerified owneron EcoPower WP110S Waterproof High Speed Metal Gear Servo

Mine just plain does not work. Right out of the box, it centered when plugged into the receiver. Then, it does nothing. The Savox it was set to replace does still react (poorly), so the fault is not in the receiver or transmitter.

What reviewers say

Reviewers of the EcoPower WP110S are split. Several praise its speed, power and value for the price, and some report trouble-free use on 1/10 vehicles including a Slash and a Fury 223s. A recurring complaint is centering: multiple reviewers say the servo does not center reliably, and one describes it as slow and veering. Other reports include a unit that stopped working, one that smoked and failed during a second outing (a replacement was reported to work), a unit that did nothing after setup, and a screw that came loose after one run. One reviewer also mentioned owning other variants (WP110T) without issue. Ratings range from 1 to 5 stars, and the reviews do not agree on overall reliability.

  • + Good speed and power
  • + Good value for the price
  • + Comes with multiple servo horns
  • + Works well on some vehicles
  • − Often fails to center properly
  • − Some units stop working or fail
  • − Reports of loose screws
  • − Reported as slow by one reviewer
