Exotek RC10 HD SERVO HORN, for 4/40 or M3 studs

Exotek RC10 HD SERVO HORN is built for precise steering on compatible RC10 setups. This heavy-duty alloy clamping horn centers the linkage cleanly over your servo case. It helps keep left and right geometry consistent for smoother, more predictable control. The included steel thread inserts let you use Associated 4/40 or M3 ball studs without extra hassle. A secure grip on the servo spline supports stable centering over repeated runs. Designed for a long steering throw, it supports full movement both directions. Choose this horn to tighten alignment, reduce unwanted link angles, and improve reliability at the track.

Designed specifically for the RC10 classic line (RC10, RC10T), this heavy duty alloy clamping servo horn helps position the ball stud directly over the servo case which aligns the link perfectly with the steering cranks. This eliminates any odd steering link angles that distorts the left and right steering geometry. And because it is designed for the RC10, you do not need to add a bunch of thick spacers that can bend or shift during a race.

Additionally- you may use the Associated 4/40 or M3 ball studs thanks to the included steel thread inserts.

The clamping servo horn also maintains a tight grip on your servo spline for perfect centering, race after race.

And of course, the horn is designed long enough to provide full steering throw right and left.

Note- for 25 spline servos only ie Futaba, Protek etc.
