Secraft Aluminum Servo Horns - Protect Your Servos Without Sacrificing Precision.
One of the greatest benefits of aluminum servo horns is the strength, rigidity & precision that aluminum has to offer - especially so with modern flybarless helicopters, which place great demands on servo arms during aggressive flight. However, with an upside, there is always the inevitable downside - rigid aluminum servo arms tend to transfer forces directly to the servos in a crash, resulting in stripped servo gears.
If this has been your past experience, you will love the design layout of Secraft servo horns - servo arms designed for maximum strength & rigidity in flight, which translates into precision where it counts. However, when those inevitable crashes occur, the Secraft arms differ, as the channeled cutaway of the servo arm is designed to fail, rather than transmitting the crash energy to expensive and difficult to replace servo gears, saving you time, money, and getting you in the air that much quicker.
Utilizing a large channeled cutout with a locking screw for maximum torque, these aluminum servo arms are strong when they need to be, yet give when overloaded, allowing your servos to be spared - all without the sacrifice of flexible, fail prone plastic servo horns that simply cannot be trusted in high servo load applications.
Available in multiple colors & sizes, Secraft servo arms are available for Futaba, Hitec & JR servos, allowing you to find the perfect application needed for your next flight.
(1) Aluminum Servo Arm (Hardware Not Included)
Futaba / Outrage TORQ / Align / SAVOX / MKS - 25T Spline
Horn Screw Size: 2.0mm (Not Included)
Material: 6061-T6 Anodized Aluminum
1st Ball Link Hole: 14mm from Output Shaft to Ball Link

* Follow aircraft manufacturers recommendation for servo horn control setup
* Use thread lock compound on all metal to metal screws
* Install linkage ball on bottom of servo arm (when / where possible)
All crashes have their own dynamic, and no crash is ever the same. These arms are designed to fail when needed in order to protect your servo gear train, but due to the many variables involved, servo gear damage is still a possibility.
