The Aeromatic propeller is a fully variable pitch propeller that is virtually equivalent to a constant speed propeller. But it is not quite the same thing. The typical constant speed (CS) propeller for a Lyc 0-320 will weigh about 54 pounds, add to that the weight of a governor and the cockpit control, you are pushing 60#. In addition to that, the engine has to have a hollow shaft in order to feed the oil to the hub.
