Not really my design, George.  I bought the PSRU I have along with the  
engine from a guy at the 8NC8 airport over in Durham.  He was building a 
2/3rd scale Stearman, and couldn't find a small radial, so he started 
designing a look-alike with a 13B as the base.  He was building it 
heavy, because the design called for a lot of weight up front.

He basically took the wheel hub from a race car and welded it to the C6 
ring gear housing.  Then pressed the works into a custom aluminum 
casting.  The gear box started at 33lbs, and I've shaved it down to 27.  
He mounted car heater cores around the bellhousing with custom made 
aluminum fins slid over them.  Looked just like jugs sticking out in the 
wind.

So as not to fill up Marv's disk space, look through my pictures here:

PSRU.jpg and BellHousing.jpg is what the gearbox and bellhousing looked 
like when I got it.  Just noticed that I don't have any pictures of it 
after my hatchet job.  I'll have to fix that tomorrow.

instinct, and morality, to just sit back and watch people make
mistakes. We want to help them, which means control them and their
decisions, but in doing so we actually hurt them (and ourselves)."
