Power HD WB-150KG – 150kg 0.09s HV Brushless Large Scale Servo

At 25.2V, the WB-150KG delivers up to 150 kg-cm of torque with a speed of 0.09 sec/60°. The servo operates within a 16.8–25.2V voltage range and is designed specifically for demanding high-performance large-scale RC applications.

The strong finned aluminium case improves rigidity and helps dissipate heat. Its brushless motor and steel gear system are designed to handle high loads and intensive use.

The WB-150KG is particularly suitable for 1:5 and 1:6 RC cars, large monster trucks, buggies and crawlers where the performance of a conventional standard-size servo is not enough.

What is the Power HD WB-150KG suitable for?

The Power HD WB-150KG is designed for large and heavy RC models that require extremely high steering torque:

• 1:5 RC cars
• 1:6 RC cars
• Large-scale monster trucks
• Large-scale buggies
• Large crawlers
• Other large-scale RC models using a 15T large spline servo

Important Power Supply Information

The WB-150KG is not a conventional 6–8.4V HV servo. Its operating voltage is 16.8–25.2V, so the vehicle’s power system must be checked carefully before installation.

Under heavy load, the servo can draw up to 6A, so the wiring and power supply must also be capable of providing sufficient current.

The WB-150KG uses a 15T large spline servo horn, so standard 25T servo horns are not compatible.
