Summary These are replacement sticks for the Eachine H8 Mini Quadcopter. It will lengthen out the sticks a little more and will soften the movement. They fit snug on my radio and do not require any glue. If they print loose for you, then you can use a drop of hot glue to secure them. *Note: The H8 and the H8S have different shaft size. Please check my other designs for the H8S sticks.
