Overview
The Kpower HBL833 is a brushless digital servo for RC aircraft, UAVs, robotics and industrial automation. Its listed 0.07 s/60° no-load speed supports fast positioning, while metal gearing and an aluminum-alloy case provide its mechanical construction. The servo measures 40 × 20 × 38 mm, weighs 66 g and operates from 4.8–8.4 V, with a listed stall torque of 10.6 kg·cm.
Features
- Brushless motor with digital servo control.
- High-precision metal gearing and an aluminum-alloy case.
- High-speed HBL833 model with a listed no-load speed of 0.07 s/60°.
- Potentiometer position sensing and two ball bearings (2BB).
- 25T output spline with a 5.9 mm diameter.
- 120° travel angle, listed as customizable.
