It functions the same as all VDM hydraulic electric propellers. It functions the same in both the FW-190 and the Bf-109 series.

The propeller is a VDM hydraulic electric propeller. It functions as a CSP in hydraulic mode (don't get confused, hydraulic mode is when the hydraulic switch is turned on) and as a variable pitch propeller with the switch turned off.

Congratulations to the Foundation, will be a very nice aircraft. It will be good to see a bird fly again.

So you are saying that the base of the propeller feather is hydraulic mechanism? I'm sure, it does not have a separate hydraulic system (for example, is something that the landing gear, or (later) the oil/water radiator). The "hydraulic systems" is in a separate chapter of the manuals, and there is no VDM parts. But this means, that it get the pressure directly from the engine? The lubricating oil used as "hydraulic fluid"? It is also true that the air compressor is doing the same way... I did not know this.
