Futaba Servo BLS 671SV – Digital HV Mini Brushless Servo
The Futaba Servo BLS 671SV is a digital high-voltage (HV) servo in mini size, equipped with a brushless motor. It supports the S-BUS2 protocol and is SR-capable, allowing flexible integration into modern RC systems.
Brushless motor for high efficiency and long life – ideal for demanding RC modeling applications.
Digital HV technology enables precise and powerful movements at high voltages.
S-BUS2 and SR capability ensure simple wiring and compatibility with current receivers.
Mini size (15x27x33 mm) fits into tight installation spaces, such as aircraft fuselages or vehicles.
24 months manufacturer warranty provide long-term investment security.
What sets the Futaba BLS 671SV apart
Unlike traditional brushed servos, the BLS 671SV operates brushlessly – meaning less wear, higher torque density, and consistent performance over its entire lifespan. Digital HV technology allows operation on high-voltage sources (up to 8.4 V), delivering increased torque in the same compact size.
Ideal for...
RC airplanes, helicopters, and multirotors where every gram counts and precision is key. Also suitable for RC cars and boats requiring compact servos with high torque.
How to use the Futaba BLS 671SV
Connect the servo to a compatible S-BUS2 receiver. Ensure correct power supply (up to 8.4 V). Mount the servo using the included screws in your model. Perform a functional test before first use.
