2 pcs one-sided and 2 pcs two sided arms for KST X06 servos. Fits 15T 4mm servo output splines.
Note these two arms are differing heights, so one servo may be placed in front of the other without the pushrods interfering. Please carefully inspect the arms to see the small differences between them.
The spline hole in these arms also fits the KST X08 servo so this product is a good alternative for the X08 arms which are slightly larger.
