The Bulldog prop is controlled by engine oil. The CTM (modified by the counterweights which are at right-angles to the prop mass distribution) drives to coarse and the oil pressure drives to fine. If the engine fails, there's no oil P and you can do what you like with the RPM/pitch lever! You certainly put the lever to max RPM(fine pitch) for PFLs for the subsequent overshoot.An engine underspeed is an indication of an oil problem and potentially serious!
The Jetstream (Astazou engine) goes fine with hydraulic P and coarse with a big f*** off spring in the prop control assembly. On shut down, if the start latches don't engage, the prop shuts down feathered due to the spring. As does the Tucano, and presumably all those small t-props which don't seem to have start latches and start perfectly well from the feathered position. (As does the Jetstream, if truth be told, because once the engine starts turning, the pressure builds quickly and drives the prop fine wards to the correct position).
Hope all this helps - glad to discuss further.
