Futaba BLS571SV S.BUS2 High-Voltage Low-Profile Brushless Surface Servo

The Futaba BLS571SV is a high-performance, low-profile surface servo engineered for competition RC cars and other installations where mounting height is limited. Its brushless motor, metal gear train, high-voltage capability, and fast response make it an excellent choice for demanding steering applications.

The BLS571SV supports Futaba S.BUS and S.BUS2 programming and is compatible with Futaba SR Mode when used with an appropriate SR-compatible surface radio system. At 7.4 volts, it delivers up to 152.8 oz-in of torque with a transit speed of 0.08 second per 60 degrees.

Discontinued—Limited Availability: Futaba has discontinued production of the BLS571SV. Any remaining inventory is available only while supplies last.

Key Features

  • Low-Profile Surface Design: Compact height is ideal for competition cars and space-restricted chassis installations.
  • Brushless Motor: Provides efficient operation, responsive control, and extended service life.
  • High-Voltage Operation: Rated for operation at 6.0–7.4 volts, with an operating range of 4.0–8.4 volts.
  • S.BUS and S.BUS2 Programmable: Compatible parameters can be adjusted through supported Futaba programming equipment or transmitters.
  • SR Mode Compatible: Supports Futaba's high-response SR Mode when paired with compatible Futaba surface transmitters and receivers.
  • Metal Gear Train: Features metal intermediate gears and a hardened aluminum final gear.
  • Fast, Powerful Performance: Produces up to 152.8 oz-in of torque with a 0.08-second transit time at 7.4 volts.
