Accurate Tail Response with Futaba BLS274SV

The Futaba BLS274SV is a compact digital tail servo built to tighten control and sharpen response on your RC craft. Its S.Bus2 programmability lets you tune endpoints, direction and failsafe behaviour for a range of flying styles and tail layouts.

Main Features for Tail Control

Advanced Modulation: Digital modulation keeps input processing precise for smoother, more consistent movement.
Powerful Torque: Provides up to 70 oz-in (5.04 kg-cm) at 7.4V, enough for firm tail authority during aggressive inputs.
Rapid Speed: Achieves a swift response time of 0.05 sec/60° at 7.4V, important for quick trim corrections.
Durable Design: Built with dual bearings and a brushless motor to reduce wear and extend service life.
Compact Build: Weighs just 53g with dimensions of 40x20x37 mm, fitting tight tail bays with minimal fuss.

A solid choice for hobbyists who want a tunable, reliable tail servo, the Futaba BLS274SV balances compact size with strong performance for demanding tail control tasks.

What voltage options work with the BLS274SV?

The BLS274SV runs between 6.0V and 7.4V. Choose a supply that matches your setup to balance torque and speed.

Can I program settings from my S.Bus2 receiver?

Yes, the servo supports S.Bus2 programming so you can adjust endpoints, centering and other parameters through compatible Futaba gear.

Is this servo suitable for collective pitch helis or tail rotors?

Its speed and torque make the BLS274SV well suited to tail rotor roles and smaller collective setups, provided the mechanical linkages are correctly matched and fitted.
