SERVOS FROM SAVÖX.
Mastering the fundamentals is critical in any creative ndeavor. Aspiring Top Chefs must master a Velouté and the other mother sauces: musicians hoping to hit
it big need to start with their chromatic scales. In that same
vein, one of the most fundamental hacks for an ambitious
roboticist is the classic full rotation servo hack. Servos are a
staple in robotics, renowned for their simplicity,
affordability, and controlability. However, many RC servos
have a limited range of motion because applications like
steering the rudder of an RC airplane do not require full
rotation. Many robotics applications, however, do require
full rotation. This month, we have the pleasure of
presenting a set of servos from Savöx, a company that
specializes in high performance servos for RC cars and
planes. In addition to testing their stock capabilities, we
wanted to execute the classic full rotation hack to see if
these servos designed for steering could deliver the same
high performance for long distance locomotion.

Savöx is a company that offers high
performance electric motors, servos, and sensors.
On the cutting edge of quality with in-house R&D
and production, some of Savöx’s flagship
products are their RC servos. Savöx servos come
in a variety of shapes and sizes, and are targeted
for use in RC cars, trucks, planes, and boats for
things like steering mechanisms. The servos we
received were the SC-1258TG model. The
technical stats on the servo are impressive. The
first thing you notice about it is the sleek case
made from aluminum that is not only durable, but
also doubles as a heatsink. The SC-1258TG boasts
a speed of 0.08 seconds/60° with an impressive
torque of 12 kg*cm. This combination is achieved
with a gearbox made up of beautifully machined
titanium gears. The unit is driven by a small
coreless motor which means that the servo has
excellent acceleration. The SC-1258TG is a digital
servo with 12-bit resolution, ensuring that it is
both fast and accurate. Quality comes with a price
