   Paul,

   I would think it would not be difficult to speak about ALL alternative
   engines.

   Besides the Reciprocating two-strokes and four-strokes, there is only
   the rotary Wankel type and the turbine.

   The turbines are usually too expensive in many way, initial cost,
   maintenance and in fuel consumption.
   The RP-engines are known in general, there is no need to discuss these.
   Here you just say that the crankshaft could be a potential hazard for
   continuous high load settings as in flying.
   Vibration is another issue not too favorable. Weight can also be
   discussed.

   Then what is left is the Mazda rotary that is available and practical.
   All that's needs is the conversion for aircraft use. That's where you
   come in.

   Regarding any "other" engines there simply are none. Period.

   Besides, the vast amount of R&D that has gone into the Wankel engine by
   Mazda can not by duplicated overnight by any other engine development.
   As stated above, there are no other alternatives around that can be
   bought, successfully used and that have a track record.
   That is always your way our of any proposal that might be mentioned.

   Just set 5 Minutes aside at the outset of you presentation covering ALL
   alternative engines.
   Also, I trust that Pat had only the Rotary in mind anyway.

   Paul,

   I called the Copperstate Forum Chairman last week about a time for
   you to give a talk on Rotary Engine.  I asked if they could schedule
   it for Sat AM.  He told me that Pat from Contact Mag. was handling
   the scheduling for the Alternative Engine Forums in Tent Five.
   These forums are loosely restricted to any engines or accessory
   topic other than certified.  The chairman told me that he would
   forward the info on your topic and time slot request to Pat.

   I suspect that Pat is having difficulty filling up the other days
   with engine topics, hence his request for you to give multiple
   talks.  As I originally requested, your talk would be on Rotaries of
   your choosing, not on alternative engines in general, as Rolf also
   pointed out.

   I'm sure there are a lot of builders here in the inter mountain
   area  (Anything East of L.A. County) that would greatly benefit from
   an introduction to Rotaries.
