Reduced Power to Increase Range in Vintage Mooney?

[Hank]

That's right--105 MPH windmilling, 100 MPH if the prop stops, but don't sacrifice altitude trying to stop it as it will restart when you accelerate back to Vg, barring mechanical issues that should stop it anyway.

If you have the guppy mouth lower closure, it helps with cooling which enables me to climb at/near Vy much of the year.

I was looking in the downloads section of this website. A member named Cruiser has a chart showing altitude vs. speed for the models except for the short bodies.
