Hi Ernest,
Would you mind posting a status report when you get this installed and
working?  It looks like a good alternative, but I don't see why each of
us has to invent the same wheel.  =20

The back of the prop flange is a good idea for mechanical attachment. =20
The only problem I see is that the shaft RPM has already been reduced=20
there.  Ground operations will only get you something on the order of=20
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=20
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=20
as I've been able to tell from the pictures.
