Dear Mr. Lamar,

I read your excellent article titled "Why not a Rotary?" in the Sport
Aviation magazine.  I was always interested in the Wankel engine principle
and would like to use one in an airplane, especially a well proven model such
as the Mazda engine.

Presently I am building a Europa XS Kit plane.  Unfortunately the Mazdda
engine is too heavy for a Europa.  Ideally I should use an engine around 110
to 120 Hp and not more than 160 lb. installed weight with accessories.

The Power-to-weight vs. HP chart in your article shows an engine:  Moller
Rotary.  This is exactly in my range of requirements.  I have not heard aobut
this engine before and I don't know where to find information on it.

I would greatly appreciate it if you could lead me to the source of
information.

They have been promising that engine for quite a few years but it does
not seem to be getting any closer to production. Royce Wise on here
is working on a light weight version of the Mazda one rotor that might come
in at 160 pounds with PSRU. To get 120 HP however you will need to
use what is called a peripheral port. An intake port directly into
the rotor housing and a 2.85 to one PSRU. An alternative would be a small
turbo charger. Up to about 175 HP would then be available for little
or no weight penalty as it would replace a required muffler.
