Todd,
Cooling air is a good idea, the permanent magnets
fail at a certain temperature, can't remember what that is though.

Not
so sure about that. I still have allot of things on my plate and I don't want
to rush things, but will try to keep it on a front burner now. You've got to
be getting close to firing it up?
I'm thinking about the cooling issue
that you are addressing with fan blades. How much heat do you think it will
generate? I'm thinking/hoping not much. I don't know about the original Harley
install, but as this is commonly used source of power, I got to looking at my
Ski-Doo, ATV and dirt bike. In everyone of them the stator/rotor is completely
sealed up and is not liquid or oil cooled. And I've never had issues with
them. It would be a simple matter for me to put a small baffle at the exit of
one of the evap cores that I use for cooling and direct some of the air over
the rotor, but due to the tight fit, not much air would find it's way under to
the stator. I'm hoping this won't be an issue. What I'm
hoping is that once the issues around fitting it in place are resolved it will
prove to be a reliable, maintenance free back-up power source without adding
any undue complexity. Of course this what we are striving for with everything
in our airplanes. But previously I've found that some simple solutions to
problems end up causing enough little other issues that the complexity results
in anything but a simple solution. And once time & money gets invested
then there becomes an incentive to keep flogging a dead
horse. I believe the concept is sound, the issue will be
in making it fit into existing RD-1? installations. If it is proven sound,
then maybe Tracy may consider working it into his RD-1 design to facilitate
easier installation, however I suspect that Tracy probably has too much other
stuff on his plate to get started reworking an already proven
PSRU.

It's in your blood, ain't it.
Sounds like you'll have your flying before I even get a first run.
