912UL - Will it windmill?

Just a dumb question I have. Will a 912UL continue to windmill if the fire goes out at normal Kitfox glide speeds? Or will the prop eventually stop. Specifically, a 80 hp 912UL with a 3 blade GSC wood prop, but any info is good.  Thanks.

On my 912 when I did switch off the engine to check out how it would glide, with a 2 blade warp drive the engine did not windmill. That was gliding at 65-75Mph. I did not try and dive to see if it would mill at higher speeds...

My 2cents

Thanks.  That's what I suspected.

Fwiw,

582 will stop at 55, slowly bump compression at 75, dive her at 85ish and it’ll airsart.  2.8:1 gears and a GSC IFA prop

Hey, I found this petrel LS doing a glide/land without engine (great exercise)

You will notice, prop hardly moves..
