Paul,
 Several months ago I related the story of the problems that company
test pilot Tom Hahn had with repeated failures of the PSRU oil supply
line. This was in regards to the Stewart S-51. This ship was the factory
demonstrator, equipped with a big block Chevy, PSRU and modified Beech
King Air prop.
 Tom recently sent me the post below. This is the result of the
company's failure to address this problem (3rd forced landing for the
same failure)
Everyone be careful out there!

one owner, only flown on Sundays, low time, motivated seller, needs a
little TLC

Their credibility is low with me. Something like this is easy to fix by replacing the
aluminum (really bad) or steel line with AN -4 or -6  double braided stainless steel
flex
line. I think they cannot admit they have serious problems with this engine because
to do so
would cause the entire program to collapse. The airplane design and engine are
closely
dependent on each other. It is not like you could take the engine out and put in a 
Lycoming.
