Futaba BLS152: Durable brushless servo for precise control

The Futaba BLS152 Brushless Super High Torque Air Servo is aimed at modellers requiring dependable, accurate actuation on substantial airframes. The brushless motor architecture extends service life significantly compared with brushed types, while dual ball bearings and Samarium cobalt magnets reduce friction and improve resistance to shocks and vibration.

Engineered for steady output and heat management

The BLS152 delivers strong torque while keeping power consumption similar to traditional brushed units. Its aluminium centre case adds rigidity and promotes heat dispersion during prolonged operation, making it appropriate for large-scale models where consistent control response is critical.

Specifications

  • Speed: 0.14 sec/60 deg at 6V
  • Torque: 430.6 oz-in (31.0kg-cm) at 6V
  • Size: 1.59 x 0.83 x 1.51 inches (40.5 x 21 x 38.4mm)
  • Weight: 2.58oz (73g)
  • Horn Set Screw Size: 3x8mm

For pilots fitting larger models, the Futaba BLS152 combines robust construction with refined internals to give dependable high torque control and lower maintenance demands.

Use it on ailerons, rudders or elevators of large models where firm, accurate movement is required and where standard servos may struggle under load.
Yes if the battery and regulator supply the correct voltage and current. Many users install a regulated 6V BEC or an appropriate battery pack to maintain consistent performance.
Routine checks include verifying horn screws, linkages and bearing smoothness. The brushless motor reduces brush wear, so mechanical checks are typically the main maintenance items.
The specified horn set screw dimension is 3x8mm; ensure compatible horns and fixings to maintain secure connections under high torque conditions.
