Tunable Control with the Futaba BLS371SV for Nitro Surface Cars

The Futaba BLS371SV offers precise steering and throttle control for glow-engine RC cars, thanks to its brushless design and S.Bus2 programming. It is tailored to surface use where quick, predictable inputs make a measurable difference on track.

Programmability and Integration

Specifically aimed at surface racing, the BLS371SV supports S.Bus2 for direct connection to compatible transmitters and receivers. Using the CIU-2 USB adapter lets you fine-tune operating parameters on a PC, adjusting behaviour to suit track conditions and driving technique.

  • Weight: 2.22 oz (63 g)

The Futaba BLS371SV is a practical choice for racers needing reliable, programmable servo control and a brushless build for long term use.

Can the BLS371SV be connected to older PWM only setups?

Yes, it will operate on a PWM channel, but programmable features through S.Bus2 will not be available unless the receiver and transmitter support that protocol.

What mounting checks should I perform after fitting the servo?

Verify the servo sits flat and fasteners are secure, confirm horn alignment at neutral, and ensure the servo travel does not bind through the steering geometry before first run.

Is additional cooling needed for endurance events?

In prolonged, high-load use consider improving airflow around the servo and avoid enclosing it in tight spaces. Good cooling extends component life in long events.
