Lynn,
Any idea what amp output would be for your motor used as an alternator after diode array
and regulated to 12-14 volts ??.............

Lynn, do you have any documentation stating a max RPM?

In the tech data the KV rating times the voltage applied gives you the prop RPM per volt. Usually 11.7 or 22 volts from Lipo batteries.
Virtually unlimited RPM as an alternator, as no copper is moving at all. No brushes to wear out or sparking.
For example a 670KV motor with 11.7 volts and a medium size prop about an 11" by 6" will turn up 7,839 RPM. You can hover a 5 pound 60" wingspan plane with that. They don't even get hot. Mine was $28.50.
