Mooney "Trapped on Top"

RPM  required to generate vacuum ?  

 

If the gyro erects at fast idle I doubt a windmilling prop is going to get that low , even with the prop pulled back...... 

My recollection is that the MB motor windmilled around 1,700 rpm with the prop reduced which should be plenty

Some aircraft (T-34A) have a detent which allows reduction of the rpm to about 700 but you can not use this range while producing power

I make a habit of flying with Flight Following whenever reasonable and possible. That way I am already talking to them if I have an issue. The more I talk with them, the more comfortable I am with letting them know what's up.
