Hi Paul
one of my aircraft owners Andrew Martin has contacted you recently re.
the design of an engine mount, I manufacture a range of light aircraft
under the brand name Australian LightWing in Ballina on the east coast
of Australia (about the middle) my company has been manufacturing light
aircraft for the past 21 years, please have a look at
www.lightwing.com.au.

Andrew is going to build one of our 4 seat aircraft.
Anyway, to cut a long story short, we have a US agent that intends
importing our aircraft and fitting (we will initially fit the engines
here) the  1 cyl Rotamax rotary to our 2 seater and the 2 cyl Rotamax to
our 4 seater.

His company is called Airgyro. What I am looking for is
someone that has fitted one of these engines to preferably an aircraft
to get some feedback on how is the best way to mount them and any
potential problems that may arise. This sort of information is always
going to be best obtained from a hands on person rather than from the
engine supplier. The Rotamax web page seems to have been last updated in
2005 so there is not much there, I believe they had an engine in a bike
at Oshkosh but thats about all I know. If you email your phone number I
will call you to save you waisting time typing. I will only take a few
minits of your time.
Regards
Howie Hughes


Yes I have recently met Nate Oldham owner of Airgyro at an airshow and
talked
to him about this. We are on it Howie. We are here to help. If you wish I
will
put you on the news letter. Expect as many as 100 emails a day in the
middle of the week. Far fewer on weekends. If an when I get a dwg of the
RotaMax engine mounts I intend doing a suggested 3D installation dwg
including
cooling recommendations for Andrew's airplane as I already did one for the
Mazda engine. The people from RotaMax are also on here.

I also have a book on on cooling the Wankel available from Aircraft Spruce
if you would like to read up on the cooling theory.

BTW I don't mind typing. I prefer it to talking :)

Paul,

Would you like me to send you a solid model of the single and twin engine?
What file format best serves you? We would appreciate any help in assembling
the necessary "fire wall forward" components for a successful installation.
We had kicked around the idea of a cradle that had the Rotax type firewall
four mount, and then extending it out whereas our engines would bolt to the
cradle and the cradle to the craft. This would give us an advantage in the
current Rotax powered and or Rotax designed aircraft.

What do you think?

That would help greatly. IGES format should work. I take it you are using
Solid Works.

I'll reserve comment on the cradle idea until I get a chance to study
a few configurations in 3D.
