ReadyToSky Aluminium Servo Horn Arm, Red

Red aluminium alloy servo horns that replace plastic arms on steering, control-surface and payload-release linkages. Three versions are offered; pick the one that matches your servo's output spline.

Key features

• 15T for ES08MA II: CNC-machined arm with a 15-tooth spline, sized for the ES08MA II 12 g metal-gear micro servo used in small crawlers and compact mechanisms
• 25T 28.5mm Half Arm: single-sided 28.5 mm arm with three holes for adjusting throw, on a 25-tooth spline for standard-size servos
• 25T 31mm Full Arm: 31 mm arm with a 25-tooth spline and M3 clamp screw that locks it to the output shaft; fits MG995, MG996R and MG946R-class servos
• Aluminium holds its shape under loads that flex plastic horns, keeping linkage geometry and centring consistent

Count the teeth on your servo's output spline before ordering: a horn only fits a matching spline, and forcing a mismatched one strips it.
