About the Servo Horn

Precision Geometry With Durable Clamping Design

Manufactured from high-quality aluminum, the 25T, 14mm height configuration ensures compatibility with a wide range of servos while being perfectly suited for the Stealth platform. The clamping design provides a secure connection to the servo spline, reducing slop and improving steering precision. Structural ribs reinforce the horn against twisting forces, while a raised boss surrounds the ball-end location for added strength during aggressive steering input. Finished in black anodizing with laser-etched JC branding and tooth count markings, this horn combines performance engineering with refined aesthetics.
