I second the motion on Pittman motors... they are the same motors that are
used on Superior Aircraft Systems SpeedBrakes, operate fine at altitude in
low temps, and are capable of withstanding vibration.  Custom windings are
available as are gearheads.  It'll be interesting to see how this turns
out.  Good luck with the prop project.
