Exotek Racing expands its support for the vintage Team Associated RC10 Classic line-up with a heavy-duty clamping aluminum servo horn, part #2392, priced at $17. Built for 25-spline servos, it features steel thread inserts accepting Associated 4/40 or M3 ball studs.

An optimized linkage geometry

The trick behind this Exotek horn: the ball stud sits directly above the servo case, eliminating the odd steering link angles found on stock horns while maintaining a tight clamping grip on the servo spline for consistent centering. Compatible with RC10 and RC10T chassis in the Classic line.
