No, it isn't a problem with the controller. You can see the target angle going up and down, yet nothing happens - also, nothing happens when the target angle is changed manually. If the parts on top of the piston get broken off, the pistons can move. I don't know about the hinge on the top.
The pistons are also a bit shaky in some cases, almost like they're trying to extend. Or maybe the Kraken is messing with me.
