These ½ arms are drilled and tapped for 3mm-linkage hardware and offer maximum steering control, as well as instantaneous throttle and brake response by eliminating the flex you often get with nylon and plastic servo arms. The “full” arm has drilled and tapped holes, as well as “blank” holes to house a wide range of throttle and brake linkage requirements.

Includes:

1 - Futaba 25T Spline - 1/2" Aluminum Servo Horn
