Stable Control with the Futaba BLS151

The Futaba BLS151 Brushless Standard Air Servo brings stable, low-wear performance to aircraft control setups. Its standard dimensions and weight suit many models, and the brushless construction gives at least five times the life of comparable brushed servos.

Components That Enhance Reliability

Magnet Quality: Samarium cobalt magnets are fitted to reduce cogging and improve resistance to impact disturbances.
Balanced Power: Uses comparable current to brushed digital servos while providing the benefits of brushless operation.
Ball Bearing Support: Dual ball bearings keep the output shaft running true for precise control inputs.

Specifications

Power Supply: 4.8V ONLY
Speed: 0.15 sec/60° @ 4.8V
Torque: 133.3 oz-in @ 4.8V
Size: 1.57 x 0.79 x 1.37" (40 x 20 x 34.8mm)
Weight: 1.59oz (45g)

For hobbyists needing durable, responsive servos in airframes, the Futaba BLS151 performs well when powered by a 4.8V NiCd pack and paired with FM, PCM or FASST radios. Periodic checks and correct mounting ensure long service life.

Can I swap this into an old model that had brushed servos?

Yes, the size is standard so it often fits older mounts, but confirm connector and travel settings and use an appropriate 4.8V supply to match requirements.

Does the servo require special programming?

No special programming is required for basic use. Set endpoints and centring in your transmitter and use recommended radio systems for reliable operation.

How tolerant is it to vibration?

The samarium cobalt magnets and robust bearings improve tolerance to vibration, but solid mounting and soft mounts where needed will further protect internal components.

What surfaces is this best suited for?

Designed for a variety of aircraft control surfaces, it is a good match for ailerons, elevators and rudders where reliable centring and torque are required.
