FrSky BLS6501H Brushless Aluminum Servo (High Voltage)
About this part
Servo Overview:
The FrSky BLS6501H Brushless Aluminum Servo is a high-performance servo designed for applications that demand precise control, powerful torque, and reliable operation. Part of FrSky's Xact series, it features a fully CNC-machined aluminum protective case, durable metal gears, dual ball bearings, and a precise Hall sensor for responsive performance. Supporting operating voltages up to 8.4V and FBUS, SBUS, and PWM protocols, this servo offers flexible integration with compatible radio systems. Its FBUS functionality also enables real-time telemetry, configurable servo parameters, and a built-in servo winch mode without requiring a separate winch controller.
About the BLS6501H Brushless Servo
Brushless Precision and Advanced FBUS Functionality
The BLS6501H combines a rugged aluminum housing and metal gear construction with fast response and powerful torque performance for demanding RC applications. Its Hall sensor provides precise position feedback, while FBUS telemetry supports monitoring of current, voltage, temperature, status, and rotation position through compatible FrSky equipment. In FBUS mode, the integrated servo winch function allows users to configure continuous clockwise or counterclockwise rotation and adjust operating speed, with support for compatible 6mm 25T winch spools. Configuration options and firmware updates help tailor the servo to specific model requirements.
