And you missed my point ack-ack; don't bring up whats already settled.
Chalenge, I meant actuall rudders like on a plane. The 'rudder' on a GV, and the rudder of a plane are only the same in the sense that we have the same name for them. I mean on a tank, its not even a physical thing, its just a name we've given to the actions of the driver opperating under orders of the tank commander.
