Futaba BLS571SV: Precision Brushless Servo for RC Steering

The Futaba BLS571SV pairs a brushless motor with a compact housing to provide precise steering control for competitive RC car rigs. Its slim dimensions help when mounting in confined chassis spaces.

Customisable Response with S.Bus2

Thanks to S.Bus2 programmable options, drivers can alter travel, centring and speed settings for a personalised feel. Performance metrics list 0.10 sec/60 degrees at 6.0V and 0.08 sec/60 degrees at 7.4V, with torques of 130.6 oz-in (9.4 kg-cm) at 6.0V and 152.8 oz-in (11.0 kg-cm) at 7.4V to handle demanding steering inputs.

For tuners seeking a compact, programmable servo with solid torque and quick response, the Futaba BLS571SV fits well into performance on-road and club race cars.

Yes, its torque and fast response times make it appropriate for front steering duties on high traction surfaces, provided the linkage and horn setup are solid.
S.Bus2 allows fine centring and travel adjustments from the transmitter, giving repeatable neutral positions and consistent steering behaviour after setup.
Its low-profile shape suits many compact or vintage chassis, but always check the dimension 40.5x20x25.4mm against your available servo bay and horn clearance before fitting.
