Futaba BLS173SVi: High-Voltage Mini Servo for Tight Builds

The Futaba BLS173SVi is a high-voltage capable mini air servo engineered for pilots who need compact, tough control gear. Its S.Bus2 programmability gives you granular setup options while delivering the torque and speed expected from a HV servo.

Built for Reliability and Control

Featuring a brushless motor and metal gear train, this servo is made for smooth, consistent actuation. Dual bearings support the shaft and help reduce wear, making it a solid choice for demanding control surfaces.

If you need programmable precision in a small form, the Futaba BLS173SVi provides rugged components and high-voltage responsiveness for serious models.

What maintenance should be done after flying?

Inspect the servo for debris and check the wiring after each session. Ensure connectors are secure and the servo horn is tight to avoid slop in control surfaces.

Can this servo handle aerobatic loads?

With its metal gears and brushless motor, the BLS173SVi handles moderate aerobatic stresses well when used within its torque limits and correctly powered at HV.

Are there upgrade paths for linkages?

You can pair the servo with stiffer control rods or ball links to reduce flex and improve precision, especially on larger control surfaces.
