The following question came up in a warbirds discussion and I couldn't find a definitive answer from a web search:
For a P-51 with a Hamilton Standard prop, if the engine loses all oil pressure (such as when Dago Red blew the side out of its motor prior to the lap record attempt in 2000), does the prop pitch go to full coarse setting (assuming it isn't already at that setting), full fine, or does it just remain at whatever blade angle the prop is in when the governor looses pressure? An answer from any team members with knowledge on this subject would be greatly appreciated.
thanks
