High torque control from Futaba BLS171HV

The Futaba BLS171HV brings strong, repeatable torque and accurate positioning to demanding RC projects. Its S.Bus programmability lets model builders refine steering and control endpoints with ease.

Quick response and steady torque

Powered by a brushless motor, the BLS171HV delivers 164 oz-in (11.81 kg-cm) at 7.4V and a speed of 0.10 sec/60 degrees at the same voltage, giving crisp reactions for tight tracks and technical manoeuvres.

Flexible integration with S.Bus systems

The servo supports S.Bus adjustments so you can tune travel, centring and other behaviours from compatible transmitters. That flexibility makes the BLS171HV a good match for multi-servo rigs and advanced control setups.

Specifications

  • Torque: 164 oz-in (11.81 kg-cm) at 7.4V
  • Speed: 0.10 sec/60° at 7.4V
  • Weight: 1.66 oz (47.0 g)
  • Dimensions: 40.0 × 20.0 × 34.8 mm
  • Motor Type: Brushless
  • Gear Type: Hybrid
  • Rotation/Support: Dual Bearings

If you need a compact, programmable servo with reliable torque, the Futaba BLS171HV fits well into performance-oriented RC models and custom installations.

What power source works best for the BLS171HV?

A 7.4V supply (2S LiPo) is recommended to reach the rated torque and speed, and you should confirm your BEC or regulator supplies enough current during peak loads.

Can I use this servo with mixed brand receivers?

Yes, as long as the receiver supports S.Bus or you use a suitable interface; standard PWM receivers can work if you configure the servo via the correct adaptor or controller.

How durable are the gears and bearings?

The hybrid gearset and dual bearing support provide solid durability for performance use, though correct mounting and avoiding overload will extend service life.

Is the BLS171HV suitable for scale servos conversions?

Its compact dimensions and torque make it useful for many scale conversions, but check horn fit and space constraints before committing to a swap.
