Power HD WB-120KG – 120kg 0.10s HV Brushless Large Scale Servo

At 16.8V, the WB-120KG delivers up to 120 kg-cm of torque with a speed of 0.10 sec/60°. The servo operates within a 12.6–16.8V voltage range, allowing very high steering force for heavy wheels, large tyres and demanding large-scale RC applications.

The strong aluminium case improves rigidity and helps dissipate heat, while the brushless motor and steel gears are designed for high loads and intensive use.

The WB-120KG is suitable for a wide range of 1:5 and 1:6 RC cars, including large-scale monster trucks, buggies and crawlers.

What is the Power HD WB-120KG suitable for?

The Power HD WB-120KG is designed mainly for large and heavy RC models that require very high steering torque:

• 1:5 RC cars
• 1:6 RC cars
• Large-scale monster trucks
• Large-scale buggies
• Large crawlers
• Axial SCX6
• Losi Super Baja Rey
• Losi Super Rock Rey
• ARRMA Kraton 1:5
• ARRMA Outcast 1:5

Important Power Supply Information

The WB-120KG is not a standard 6–8.4V servo. Its operating voltage is 12.6–16.8V, so the vehicle’s power system must be checked carefully before installation.

Because of its high performance, the servo can draw up to 8A under heavy load.

The WB-120KG uses a 15T large spline servo horn, so standard 25T servo horns are not compatible.
