Hi Ernest,
i researched this topic just a few weeks back; I think a Harley M/C alternator is just right for the rotary. 25, 32, and 45 amps available OK to 9000 rpm. I think I will mount mine on the prop flange. Check out www.compufire.com All courtesy of Leon Promet
The back of the prop flange is a good idea for mechanical attachment. The only problem I see is that the shaft RPM has already been reduced there. Ground operations will only get you something on the order of 300RPM. The Compufire unit is supposedly wired to give you more current at low speed, but putting it before the PSRU will keep you from having to stress the unit's low speed ability.
My plan has been to put one on the input shaft of my PSRU. I have a 1", 10-spline shaft, which is what these units were designed to take as far as I've been able to tell from the pictures.
