A stylish way to add functionality to your aircraft!


Servo arms are a critical, yet often overlooked, component of an
aircraft’s setup. They are a component that is often selected at
the last moment in an aircraft’s assembly, however are quick to
receive blame any time there is loss of control of the aircraft.
A quick glance at these arms reveals beautiful execution of a very
simple item, but once you get past the stunning blue anodized
skin, the attention to detail becomes quite visible. Each arm is
carefully machined from the highest quality aluminum bar stock to
the tightest of tolerances. They are much thicker than typical
aluminum servo arms for better shear and tensional strength. The
hubs are even thicker than the arms for maximum strength and
surface contact with the servo’s output gear. Also a unique
feature to the hubs is the secure, locking clamp design that will
tighten to your servo to virtually eliminate any mechanical slop,
yet release for easy removal from the servo with no tools, scraped
knuckles, bent arms, or bad words uttered.
Polished, bevel-cut edges and laser-engraved JR logo add the
finishing touches to the arms and give an appearance that is
several levels above anything else in the market with performance
to match. Try a set out on your new project. We’re sure you’ll feel
the difference!
