Paul, I read the statement of Butch and have to agree that Jurgen did not
mark it very well at all.  It is absolutely necessary that a comapny like
Jurgen's would have given engines to kit manufacturers to install in their
demo aircraft.  I tried to get Jurgen to give an engine to B.J. Schramm
(helicycle).  Nothing came of that whatsoever.  When I told Jurgen that I was
going to put the two rotor engine into the revolution helicopter I not only
had to buy the engine but I also was charged for things I would not ever use.
 He did give me a 25 percent discount.  To get information on the fuel
injection of the engine was a labour of love.  To get full scale prints for
engine installation was impossible.  The marketing of the engine left
something very grave to be desired.  The problem with the engine is that the
manufacturing process necessary for the housing rotor is not done easily and
that the coating of the engine pieces (nickasil) is not easily done by an
American manufacturer.  

I talked to my metalurgist friend and he also agrees
that the detonation coatings are probably the way to go.  Jurgen has a great
number of patents covering his engine which are unique to the engine.  I
don't know if you have ever seen an engine taken apart but it is not a simple
Mazda configuration.  I wanted to manufacture and market this engine if we
could still get the patents and tooling.  I would welcome any and all to join
in this effort.  We have CNC machines and time available to do the job.  If
you could get a consortium of people together that would be terrific.

Well perhaps if he is going to hold us up on the patents perhaps it
would be cheaper to design from scratch a smaller, all aluminum P-Port version
of the Mazda 13B specifically for ultra lights with detonation gun coated
rotor housings to avoid the high tech steel liner. I have a few ideas
for improving the water flow in the block as well. In the quantities we
would sell initially sand cast housings maybe be cheaper than die cast 
housings anyway.
