Compact High Voltage Rudder Servo

The Futaba BLS256HV is a compact, high voltage brushless servo engineered for precise rudder control in gyro-assisted models. Designed to accept 2S LiPo input it offers a blend of speed and torque to tighten tail tracking and reduce drift.

Designed for Stable Tail Control

The brushless design of the BLS256HV provides sharp, repeatable motion and fine centring. Its speed specs and torque ratings support steady corrections from the gyro under typical flight loads. This servo is a solid match for advanced gyro controllers where predictability matters.

Specifications

  • Speed: 0.055 sec/60deg at 6.6V, 0.050 sec/60deg at 7.4V
  • Torque: 61.1 oz/in (4.4 kg/cm) at 6.6V, 69.5 oz/in (5.0 kg/cm) at 7.4V
  • Size: 1.57 x 0.79 x 1.45" (40 x 20 x 36.8mm)
  • Weight: 2.15oz (61g)
  • Power Supply: 6.0 - 7.4V DC

For modelers seeking a compact servo with reliable speed and torque the Futaba BLS256HV delivers consistent behaviour and clean gyro integration.

Will this servo fit standard tail servo bays?

The BLS256HV uses common compact dimensions but always check mounting hole spacing and clearance. It is designed to fit many helicopter tail servo bays with minimal modification.

How should I power the servo to avoid noise or interference?

Use a stable, filtered supply inside the 6.0-7.4V range and consider a dedicated BEC for the gyro and tail servo. Good wiring practices and common ground help reduce electrical noise.

Can I use the BLS256HV on larger scale models?

It depends on load demands. Check the torque specs against your tail size and expected forces. For very large tails you may need a higher torque unit, but for many mid to large electrics the BLS256HV is appropriate.
