Futaba BLS571SVOS O.S Tuned Speed T1 - low profile 41g servo, 0.10s, 9.4kg-cm  [BLS571SVOS]

Futaba BLS571SVOS - compact speed for sharper control

In tight races every input counts. The Futaba BLS571SVOS provides fast, accurate motion in a compact form factor. With O.S tuning applied, this servo targets pilots who want quick, dependable actuation without added weight or bulk.

Core strengths and technical summary

The Futaba BLS571SVOS packs strong credentials into a small body. It weighs 41 grams, moves at 0.10 second per 60 degrees and delivers 9.4 kg-cm torque at 6.0 volts. Those figures suit on-road classes and light off-road rigs that require immediate steering correction.

The O.S tuning enhances response smoothness and power delivery, reducing erratic motion under aggressive inputs so steering remains predictable during hard cornering.

Quick setup guidelines

To make the servo perform reliably, use a fast receiver and keep servo endpoints trimmed in the transmitter. Match horn length to steering geometry and supply a steady 6.0 volt source. These adjustments help exploit the BLS571SVOS speed and holding power on track.

When to upgrade to this Futaba servo

If you are replacing a standard hobby servo, the Futaba BLS571SVOS offers a noticeable jump in speed and torque. Its tuned behaviour and build quality make it a practical upgrade for racers and advanced hobbyists focused on consistent lap times.

For compact, fast actuation and reliable holding power, the Futaba BLS571SVOS is well suited to drivers upgrading their steering and control systems for better on-track performance.
