Overview
The Kpower HBL830 is a digital brushless servo for RC car steering, model-aircraft control and laboratory automation. Its no-load speed is 0.05 ± 0.01 s/60° at 7.4 V, supporting applications that need quick linkage movement. A 25T, 5.9 mm output spline, metal gearing and dual ball bearings provide key mechanical selection details, while a 300 mm lead helps with installation planning.
Features
- Digital control with a brushless motor.
- Low-backlash machined metal gears.
- 7075 aluminum case.
- Dual ball bearings and a 25T output spline with a 5.9 mm diameter.
- Potentiometer position sensing, with magnetic encoder customization supported.

Customization Requirements
Discuss required wire length, control type and position sensor with the supplier. Magnetic encoder customization is supported; the specified standard position sensor is a potentiometer.
Applications
- RC car and off-road vehicle steering: The 0.05 ± 0.01 s/60° no-load speed at 7.4 V supports quick steering-linkage movement, while the 25T output provides a defined horn connection.
- RC airplane control linkages: Use the digital brushless servo to actuate model-aircraft control mechanisms, with multiple horn shapes available for different linkage arrangements.
- Laboratory automation: Drive small positioning linkages using potentiometer feedback and low-backlash machined gears.
- Drone mechanism actuation: Operate servo-driven linkages where the specified mechanical dimensions, spline and control requirements suit the mechanism.
What's Included
- Kpower HBL830 servo.
- Four servo horns: one round disc, one two-arm horn, one four-arm horn and one six-arm horn.
- Four black mounting grommets.
- Four brass-colored mounting eyelets.
- Four silver-colored mounting screws.
- One black machine screw.
