High-Response Brushless Tail Servo

The Futaba BLS256HV is a high-voltage brushless servo tailored for precise rudder input in gyro-equipped models. Able to run from a 2S LiPo source it delivers the quick movement and torque figures needed for aggressive or precise flight styles.

Features for Smooth Control

Its brushless motor architecture yields rapid, smooth travel and precise centering. The BLS256HV balances speed and torque so gyro corrections remain proportional and stable. It integrates well with advanced gyro systems to enhance tail authority.

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

Ideal for flyers who adjust aggressively or demand tight tail response, the Futaba BLS256HV provides reliable output and predictable gyro interaction.

Can the BLS256HV handle continuous high loads?

The servo delivers the torque figures listed but continuous extreme loading will stress any servo. Match the servo to the tail rotor size and avoid binding to prevent overheating.

Are there upgrade parts recommended for installation?

Use quality metal control horns and hardened linkages to make the most of the BLS256HV torque. Upgraded servo arms and tight linkages reduce play and improve feedback.

How do I tune servo endpoints with a gyro?

Start with conservative endpoints and lower gyro gains, then increase travel and gain incrementally while monitoring for oscillation. Small adjustments yield the best results.
