Futaba BLS351 Servo Engineered for Control

The Futaba BLS351 Brushless High-Torque Servo is made for pilots and drivers who want accurate, repeatable movement under load. It combines a sturdy gearset with efficient motor design to support serious RC tasks.

Brushless Motor Benefits Explained

The brushless drive in the BLS351 reduces heat and wear compared with brushed equivalents, helping the servo to maintain steady output during lengthy sessions and heavy use.

Notable Mechanical Features

  • Magnets: Fitted with Samarium Cobalt magnets for reliable magnetic force and efficiency.
  • Bearings: Dual ball bearings smooth the gearbox and improve response times by approximately 30 percent.
  • Gears: Metal gears are specified to withstand high-torque demands without premature wear.
  • Warranty: Supplied with a one-year warranty to cover manufacturing faults.

Compatibility and Installation Guide

Standard sizing and a universal connector let the BLS351 drop into many models with minimal modification. A round horn is pre-installed and extra mounting parts are included. Ensure your NiMH or LiPo supply can deliver the current the servo draws under peak load.

Specifications

  • Torque: 4.8V: 173 oz-in, 6.0V: 217 oz-in
  • Speed: 4.8V: 0.16 sec, 6.0V: 0.13 sec
  • Dimensions: 1.6 x 0.8 x 1.5" (40 x 20 x 37mm)
  • Weight: 2.2 oz (63g)

For enthusiasts needing a compact, powerful servo, the Futaba BLS351 combines torque and precision for competitive and demanding recreational use.

Yes. The BLS351 operates with standard servo signals used by digital transmitters. Match endpoints and subtrim in your radio to optimise travel and centring.
In most cases you can swap a brushed servo for the BLS351 provided the mounting pattern and horn fit. Check battery and power system capacity to handle the higher current draw under load.
Listen for unusual noise and feel for play at the output horn. If you detect slop or skipping under load, remove the servo for inspection and replace worn parts as needed.
