With the first two, you could indeed overrev your engine in a dive, hence the limit set in the pilot's manual. You will be able to overrev your engine in the sime flying de Havilland Mk.I fighters (Spitfire Mk.I and DH-20 Hurricane Mk.I),

klem - I do have great copy of Hurricane Mk.I pilot notes and maintenance manual dated March 1939, all pre-BoB Merlin II and III related. Great stuff, PM me if you'd care for a copy.

Thanks Robo, I forgot it wasn't a constant speed prop on these early machines Dohhh! The reason I ask is that I've seen reference to overspeeding props in manuals for aircraft with constant speed units fitted and was wondering under what circumstances an overspeed could happen.

I guess slamming the throttle to max when going into a dive might not give the constant speed unit time to adjust?

Exactly.
