BTW did anybody read the March Kitplanes article Meredith Effect Fact or Fiction?

   Kitplanes is doing a ten times better job than EAA Sport Aviation mag.

   Can anybody that has my book tell me the key facts the author is missing ? :)

         I read the article... but I have not bought your book yet

         What did you think of the article? Did it answer all of your questions ( if any) :)

         Paul Lamar


   No it did not answer all my questions. ..I was somewhat disappointed in the article. ..
   .looking for more science to use in making decisions

   You will get it in my book Bill :)

   Dear Paul,
   The article "hit the spot" for me. Anyone that has the slightest interest in "alternative" power for aircraft would certainly want to know more. Whether anymore "science" was required is debatable.

   I have been watching developments of various power plants, and read many articles that have been written by individuals who have fitted (or failed to fit) an alternative engine in their aircraft. The only uint that seems to have had some success is William Wynne with the corvair engine. I attended his "college" at Leesburg last year, which was very useful. The output is not sufficient for my needs but I wanted to see how the "college" concept worked. I believe that his approach and his enthusiasm has resulted in a very high percentage of successful completions.

   I am very interested in building an aircraft (Glasair ll/lll) with a rotary engine, but I have neither the engineering background nor the time for such a project with the resources that seem to be available . On the face of it seems that there are several individuals working on projects (some of which exchange information) constantly re-inventing the wheel.
   I am not suggesting that I am so inept or lazy that I just want to "walk into a shop" or contract a company to produce a FWD solution. I am well capable of maintaining my own aircraft and have rebuilt several conventional auto engines, but from what I have been able to glean, the Wankel, although simple in concept does present real challenges when adapted to an aircraft.

   I have just watched your 2009 Wankle Ag interview on youtube.com <http://youtube.com> <http://youtube.com>. I see that he has a "double engine" driving a single shaft. Has anyone tried this configuration with say, 150 hp/engine, total 300 hp? It would give almost the security of a twin engine aircraft without the assymetric problems. Just a thought. I don't have dimensions or weights so it may well be totally impractical.

   Apart from Tracy Crook's book, and your book are there any more publications directly related to rotary engines in aircraft?
   Now that Tracy Crook has "retired" who is the "go-to" source for parts/components - fuel injection, manifolds, radiators, psru etc. etc required to convert for example a 13 or 20 series engine?

   I know that you are off to Europe soon, and as I will not be back in the US until the beginning of March, so an early reply is not needed.
   I am enjoying reading the posts, although many are way above my pay scale.
   Enjoy Europe

   Do you have my book? The Kit planes article system will not cool a rotary.
   There is a lot missing in the article.

   The ACRE NL web site is more than a book if you read it all :)
   There is very little that is not covered.

The rotary is less of a problem than converting a recip engine for aircraft use. The basic engine assembly is bullet proof if assembled with due care. Paul's recommendations regarding rotor housing seals from Creavy, and his cooling system book along with the web site information are to be paid attention to. P-port and mount parts from Jeff, EFI via Motec and Paul's new ignition and universal mount will get you in the ball park. Look around for a used or Tracy PSRU. 250HP to 300HP depending on the PSRU ratio. The cost for the install will be less than a new Lycosaur. If you fret about the fuel system you could mount an extra fuel pump, ECU and injectors to A/B and be able to switch if a problem comes up.
