This is the Max6.
Installation shows the bolt goes into the nut then into the metal holder that holds arm. It can’t be right!
There’s no way to tighten it and worse, it’s damn hard to dismantle when we install it bolt into the metal holder then the nut in plastic arm holder that has the Leyi logo.
This is how it’s suppose to be install in order for it to be held tightly. The nut is inside the red holder.
