One strong aluminium servo output arm (horn) that fits KST servos with a 6 mm output spline. This is used on KST servos 15 mm thick and larger. Does not fit the KST X08 or X10 servos.
Also fits most Blue Bird servos apart from the tiny BMS-101 and A10 series.
Contains one substantial metal output arm only. The distance from the servo output shaft axis to the holes ranges from 18.5 mm to 24.5 mm.
Clamped in place using a hex end screw. Allen key not supplied.
