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.
