About the WP173-X24 Servo


Design

Unlike all other traditional servos on the market, the EcoPower WP173-X24 micro Servo features a first of its kind innovative built-in direct axle and links mount system that revolutionized the game by allowing the WP173 to be directly mounted to the SCX24 axles with no need for a servo mount! This brilliant mounting system provides a sturdy and rigid fit with extra clearance between the chassis rails!

Extreme Torque & Speed

Whether you are into hardcore Comp rock crawling, backyard crawling or just hitting the trails, a high-torque and speed steering servo will always be at the top of the upgrade list, especially for rigs with heavier tuning weights and wheels! This EcoPower WP173-X24 micro servo is capable of outputting 173oz.in (12.5Kg-cm) of torque and 0.07 sec/60 of speed at 8.4 Volts to turn even the heaviest micro rig wheels smoothly, precisely and with ease!

Robust Construction & Drivetrain

When it comes to durability and reliability, the EcoPower WP173-X24 micro servo is fitted with all metal heavy-duty gears, an all-aluminum finned case to maximize heat dissipation and an aluminum 25T servo horn to ensure maximum durability and flex-free operation under the harshest conditions! In addition, the EcoPower WP173-X24 is fully elements and waterproof! Allowing you to navigate through wet and dirt-filled trails with peace of mind!

Seems to be a great servo good power nice quality, but unfortunately doesn’t work with the MEUS Scx24 axles the dif cover plate contacts the link mount that is on the servo and won’t allow you to mount this servo on that axle. Will mount on stock style axle and dif covers.

Awesome upgrade for the scx24. Direct fit and easy to install

Didn’t even make it 2 months. The direct mount to stock axles was nice but wouldn’t buy this again.

What reviewers say

Five verified owners rated this SCX24 direct-fit waterproof aluminum digital micro servo between 1 and 5 out of 5, averaging about 3.2. Two reviewers reported gear stripping within a few months, one of whom noted the warranty excluded gears and that replacement gearsets were not apparently sold. One reviewer said the servo was quickly warrantied by the seller after gear failure. Reviewers agree it fits stock-style axles and differentials with a direct mount and is easy to install. One reviewer praised power and build quality but found it incompatible with MEUS SCX24 axles because the differential cover contacts the link mount on the servo. Gear durability is the recurring concern, and reviews are few.

  • + Direct fit on stock SCX24 axles
  • + Easy installation
  • + Good power and build quality
  • + Quick warranty replacement reported
  • − Gears strip after a few months
  • − Gears not covered by warranty or available as spares
  • − Incompatible with MEUS SCX24 axles
  • − Fails to last beyond two months for some owners
