Thanks for the response.  I too am using Bob's Z-14
   diagram....as a
         matter
         of fact it is literally what I am working on now.....today, even,
         if'n I get
         out there, which I hope I do.  Bob is scheduled to come to
   speak to
         my EAA
         chapter (EAA Houston, Chapter 12) in October.  He expressed
   his lack of
         desire to come during a Houston summer <g>

         My most pressing question right now has to do with the
   placement of
         the fuel
         pressure regulator.  I have gotten different perspectives from
         difference
         folks as to whether it should go inline before the injectors or
         after the
         injectors.  The concern and/or confusion comes mostly from the
         "pin-hole" in
         the fuel rail.  One engineer says the pin-hole will be acting
   as the
         pressure regulator so no other is needs, another says it should go
         before
         and still another says it should go after (like many auto's
   do).  I
         guess
         this is one of the problems that goes with being at an airport
   with
         dozens
         of ROCKET SCIENTIST (we are NASA's Johnson Space Center's main
   field
         (EFD -
         Ellington Field).

         I have most the fuel system complete, except for this one
   little item.
         Several emails have been sent to Mistral, but we have had no
         response.....guess I am too small a fry with just the
   intake/fuel rail
         purchase (even though I am thrilled they made it available).
   Since
         I am at
         a bit of a hold up with the fuel regulator, I moved onto the
         electrical. I
         have wired most of RWS (Tracy Crooks') ECU and started its
   install and
   I
         have the "big wires" installed in my Velocity.  Should be mounting
         the B & C
         contactors, regulator and busses etc later today.....well, in
   theory.
         THANKS AGAIN.

         All the best,

         Chris

   Chris,
      I posted this for a Mistral manifold user on Flyrotary a while back.
   The functionality is the same as other systems and allows the "bypass"
   function for repriming should you run a tank dry. You still need the
   regulator. The small hole doesn't perform the regulation function. You
   still need a pressure regulator with a manifold pressure tap (reference)
   for things to work correctly. The regulator maintains a constant
   pressure delta relative to manifold pressure to work the best.

   There has lately been a thread on this newsletter which questioned
   Mistral
   Engines' support to some of its customers.  This is inexact and I
   would like
   to set the record straight:

   1. Mistral never sold anything to any Chris.  Having said this, we
   did sell
   an intake manifold and fuel rail kit in July 2006 to Mr David S. in
   Texas.
   We believe but have never been formally notified that David and
   Chris are
   partners on a rotary powered Velocity.

   2. In August, David came back with some questions which Mistral's Chief
   Engineer, Gordon Anderson, answered at length on 8/14/06.

   3. On 3/2/07, I received an email from Mr Blaine S. from Texas, who
   mentioned that he was working with friends on a rotary powered Velocity
   equipped with Mistral's intake system and fuel rail, but he didn't name
   these friends.  Blaine asked questions pertaining to Mistral's fuel
   rail and
   fuel system in general.  Gordon answered them at length, together with
   excerpts of some Mistral's manuals, on 3/19/07.

   4. Neither Gordon nor myself have received any other communication from
   either David, Chris or Blaine.

   Mistral Engines DOES SUPPORT ALL ITS CUSTOMERS to the best of its
   technical
   and human resource capabilities.  In the present case, the total
   time Gordon
   spent supporting this sale ate up pretty much any profit margin we
   may have
   had.  That's OK but everyone will agree that it cannot become a rule.
   However, let me state here that Mistral Engines will keep supporting its
   existing spare part customers.

   If an email from Chris got lost, which is of course possible, we
   sincerely
   apologize to him and ask to please resubmit.  However, in the case
   of his
   questions relative to the fuel rail, we believe we answered his
   partner last
   month, within a couple of weeks of the inquiry.  May I humbly
   suggest that
   partners within a project identify themselves clearly to us or,
   better yet,
   that all communication be routed through the purchaser, because that
   is how
   we keep our client files.

   Fly safe,

   Francois Badoux
   CEO, Mistral Engines



These guys are definitely from France, right?
