Precision actuation by Futaba BLS171HV

The Futaba BLS171HV offers robust torque and accurate positioning for demanding control tasks. Its S.Bus programmability makes it suitable for complex installations where fine tuning is required.

Strong torque with fast response

The brushless drive in the BLS171HV generates 164 oz-in (11.81 kg-cm) of torque at 7.4V and achieves a speed of 0.10 sec/60 degrees at the same voltage, delivering reliable performance for competitive and technical use.

Configurable via S.Bus for tailored behaviour

S.Bus support lets you customise travel, centring and other parameters from a compatible transmitter, making it easier to match the servo to different control surfaces and linkages.

What current draw should I expect from the BLS171HV?

Current draw varies with load, but expect higher peaks under heavy or stalled conditions; ensure your BEC or regulator can handle surge currents for safe operation.

Is the BLS171HV waterproof or splash proof?

The BLS171HV is not specified as waterproof; avoid exposure to water and protect the servo in wet conditions or choose a sealed alternative for aquatic or all-weather use.

Can I use this servo for steering and throttle duties?

Yes, the torque and speed profile suit steering and throttle applications in cars and boats, provided the mechanical setup matches the servo's size and torque capability.

What mounting considerations are there for installation?

Ensure secure mounting to avoid flex, use correct screw types to prevent stripping and verify horn alignment to reduce side loads on the bearings and gear train.
