Futaba BLS452: Responsive Brushless Steering

The Futaba BLS452 is a brushless high torque servo tailored to electric RC cars, trucks and boats. It aims to provide smooth, predictable steering feel across varied driving conditions.

Durable Geartrain and Strong Torque

Metal gearing gives the BLS452 resilience against wear and ensures consistent force when tackling sharp turns or heavy loads. The brushless motor contributes to steady output and reduced maintenance.

Specifications

  • Speed: 0.19 sec/60° at 4.8V; 0.15 sec/60° at 6.0V
  • Torque: 200 oz-in (14.4 kg/cm) at 4.8V; 250 oz-in (18.0 kg/cm) at 6.0V
  • Dimensions: 1.6 x 0.8 x 1.5" (40 x 20 x 37mm)
  • Weight: 2.2 oz (63g)
  • Horn Screw Size: 3x8mm

Whether used for club racing or off-road fun, the Futaba BLS452 balances compact sizing with the torque needed to improve steering authority on demanding courses.

What installation tips help prevent binding?

Ensure the servo output spline and horn are aligned with neutral, and set travel/dual rates on your transmitter to avoid overtravel and binding.

Can I use the BLS452 in a crawler or rock racer?

The torque is useful for higher load applications, but check gear ratio, mounting position and servo size for crawler setups where slow, high-precision movement is needed.

How do I check horn screw compatibility?

The BLS452 uses a 3x8mm horn screw; confirm your horn accepts that screw size or use appropriate adapters to secure the horn.
