OK FGD
t303, your account refers to simulating the engine failure by setting flight-idle. Flight-idle is not the same as windmilling. This is twice now that I have called you on this.
I mistakenly thought the argument was concerning drag, your concern being about a windmilling prop, lack of climb performance and all. I offered my experience in the aircraft with the gear out (lots of drag). My bad, so I'll fold.
Life's too short.
