What was the prop pitch on your RV3. Did the prop stop during the glide or
continue windmilling? I had a PA20 piper with a 74-52 prop, I used to
take it out over a large river sandbar and practice engine out landings. It
glided measurably better with the prop stopped than it did with it
windmilling, or idling.

Don't remember the pitch but cruised at 198 (at)2700.
Wood props and high compression don't windmill, would stop in a few
revolutions.
Could airstart at abiut 150 or so . John
