KingMax BLS1506L HV Brushless Low Profile Digital Servo

The KingMax BLS1506L is a high-speed, low-profile HV digital servo designed for RC aircraft applications where fast response, compact installation height, and precise control are important. With a brushless motor, 7075 aluminum gears, full CNC aluminum case, and up to 17.8kg-cm (247.24 oz-in) of torque at 8.4V, this servo is a strong choice for thin wings, pattern aircraft, sport jets, and other tight servo installations.

The low-profile case helps reduce installation height while still providing HV performance from 5.0V to 8.4V. The BLS1506L also includes dual ball bearings, waterproof construction, and SSR mode availability.

Why Choose the BLS1506L?

The KingMax BLS1506L is best positioned as a fast, compact, precision-focused servo. Its low-profile case makes it useful where a standard-height servo may not fit, while the brushless motor, CNC aluminum case, 7075 aluminum gears, and HV capability give it the performance needed for demanding aircraft installations.

Note: Maximum torque and speed ratings are achieved at 8.4V. Actual performance may vary depending on voltage supply, linkage setup, aircraft application, and installation.
