Overview
The Hot Racing Aluminum 25T Double-Lock Servo Arm (Untapped) is a builder-friendly servo horn for 25-spline servos from Futaba, Traxxas, Savox, Orion, and ProTek. CNC-machined from 6061-T6 aluminum and finished in clean black anodizing, this horn features a double-clamping locking design and two pre-drilled 2mm pilot holes that you can tap or drill out to your custom steering linkage requirements.
