Futaba BLS571SV: Compact Brushless Servo for Tight Chassis

The Futaba BLS571SV offers brushless motor efficiency in a low-profile package, making it a solid upgrade for racers needing improved steering authority without sacrificing fit. It works well in compact bays and tight internal layouts.

Responsive Drive and On-the-Fly Settings

Featuring S.Bus2 programmability, the servo allows in-field adjustments to suit track conditions or driving style. It posts 0.10 sec/60 degrees at 6.0V and 0.08 sec/60 degrees at 7.4V, and delivers 130.6 oz-in (9.4 kg-cm) at 6.0V and 152.8 oz-in (11.0 kg-cm) at 7.4V for dependable steering inputs.

Specifications

  • Speed @ 6.0V: 0.10 sec/60°
  • Speed @ 7.4V: 0.08 sec/60°
  • Torque @ 6.0V: 130.6 oz-in (9.4 kg-cm)
  • Torque @ 7.4V: 152.8 oz-in (11.0 kg-cm)
  • Dimensions: 40.5x20x25.4mm
  • Weight: 41g
  • Rated Voltage: DC 6.0V-7.4V
  • Operating Voltage: 4.0V-8.4V

Choose the Futaba BLS571SV when you need a compact, high-voltage servo that gives predictable steering and easy programmability for competitive setups.

Do I need a special receiver to use S.Bus2 features?

You need a Futaba receiver or controller that supports S.Bus2 to access advanced settings. Standard PWM receivers will run the servo but without S.Bus2 programmability.

Can the servo handle 2S LiPo voltages reliably?

Yes, the BLS571SV is rated for DC 6.0V to 7.4V and performs well on 2S LiPo systems within that range. Ensure wiring and connectors are solid to maintain stable voltage under load.

What maintenance keeps this servo performing well?

Regularly check linkages for slop, confirm gear mesh and keep the casing free of grit. Replace worn horns or mounting hardware to avoid binding that stresses the motor and gears.
