ControllerAcc is the value for an object's controller acceleration in m/s, hovewer, almost all people which script them use it as a way to store data. my AK-47 uses it as a method to tell the ammo remaining in clip

HOW?? How does it tell? please give me an example... an easy one

For on collide do something like:  ControllerAcc = ControllerAcc +1

Now every time that object hits something it's controllerAcc variable goes up one.  You can then use that variable to tell the object to do something else.  The only thing about this that's better than custom variables is that you can clone the object and it's clone can do the same thing without having to make a new custom variable.

its impossible to set a hinge speed using only controlleracc. you need a scene.my variable to do so, unless you manage to make a VERY complex collision group array
