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 ? :)

Paul Lamar


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

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

ATP Bill

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.

Paul Lamar



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.

   Did I tell you about the new, US Army surplus air cooled Teledyne engines offered in ebay?
     Prices range from $400 to $800, and powers are stated as 8 to 40 HP.
    It's concurrence to RCEs and much complex and unsafe, but prices look right. Or not?
     Thanks, have a nice weekend. Best regards. Salut †
