Power HD WT120 Brushless Crawler Servo - 50kg 0.08s
Brand: Power HD
Part No: HD-WT120
Shadow Stock: Usually ships within 4-5 days
The Power HD WT120 Brushless Crawler Servo (HD-WT120) delivers serious holding power and speed for scale and competition rigs. With up to 50.0 kg-cm torque at 8.4V and a swift 0.08s transit time, this brushless, steel‑geared servo is built for demanding terrain and precise control.
A pure brass case allows the WT120 to act as a functional balance weight. In chassis designed with a servo on the beam (chassis mount), the added mass helps settle the front end. In servo-on-bridge (axle mount) competition setups, additional weight at the axle can enhance crawling posture and grip.
The WT120 supports the FlySky i-BUS2 protocol, enabling real-time servo status viewing on FlySky NB4 series radios, with on-radio parameter programming for quick trackside adjustments. Rugged steel gears and IP67 waterproofing provide durability across varied conditions, while smooth dual ball bearings and a compact 41.0 x 20.0 x 29.0 mm footprint make installation straightforward.

The cases of WT162 and WT120 are made of pure brass material and can be used directly as balance weight servos.
When WT162 and WT120 are used in a simulated crawler chassis designed with a servo on the beam, the weight on the beam can be heavier and the posture of the whole car can be better.
When WT162 and WT120 are used in a competition performance crawler chassis designed with a servo on the bridge, the weight on the bridge can be higher and the crawling performance can be better.
Both WT162 and WT120 use brushless motors and support the FlySky i-BUS2 protocol. The servo status can be directly observed on the FlySky NB4 series radio in real time, and the servo parameters can be programmed on the radio.
WT series servos are all made of steel gears, IP67 waterproof, durable, and can be used in various environments; they perform well on 1/10 and 1/8 simulation crawlers and competition crawlers.
