A big windmilling prop is much worse than engine at idle.
Like Ron said: be careful out there.
When I bought my Fly Baby, the idle was set to about 750 RPM. I thought that was fine, and flew for a number of years.

That change in RPM made a bit difference...probably about the same between idling and windmilling.

I just read this crash report where a low flying pilot let his groundspeed decay from 105 to 41kts just before impact. (GPS recorded)
Then he asked the first responders "what happened".
