KST 25T-6mm Arm Set – Also Fits Blue Bird Servos

Four assorted heavy duty red plastic servo output arms (horns) that fit all KST servos with 6 mm diameter 25 tooth output splines. We think this is most KST servos greater than 12 mm thick.

Also fits most Blue Bird servos apart from the tiny BMS-101 and A10 series.
