Paul,

When you say rotor head, I think helicopter--sorry.  I'll check the map and
possibly swing through from Riverside.  Do you have the address?  Did you
check out those Rotamax guys?

Sneaked up on us this year. It is TOMORROW.
Is anybody going besides myself.

Paul Lamar ...No rotor no motor.



Paul,

What's this?  I'm planning to go to Flabob tomorrow--it's Chapter One Open
House.

Another subject--I just received my September Sport Aviation and there was a
thing about Rotamax.  I've never heard of them but I checked their website:
www.rotamax.net
There is a bunch of interesting stuff here.  Apparently, they're working on
three and four rotor variants.  They are based in Ohio and the engines are
almost all aluminum.  I think they are the same displacement as the Mazda
and the website says that they use Mazda seals.  Have you checked these guys
out?

It is the largest meeting of rotor heads in the world. Hundreds of cars
show up from all over the US with about 5000 people.
Google Seven Stock 2007 It is in Irvine at the Mazda distributor.
You will see all sorts of things up to 4 rotor engines.

Don't miss it Steve. A lot better than any EAA chapter meeting :)
Most of the aftermarket rotary venders will be there. RB, Mazdatrix,
Paul Yaw sometimes from as far away as Aus and NZ.

Yes we have had a lot of RotoMax stuff on here. It is derived from the OMC
rotary engine by way of Moller. Paul Moller told me on Tuesday they copied
his design. It is charged cooled so you pay a HP and BSFC penalty right
there. Charge cooling works by passing the air fuel mixture through the
rotor first to cool it. The problem with that is the charge picks up heat
and the VE is poor due to the tortuous path the mixture must take to make it
to the compression chamber. Not at all like an oil cooled Mazda rotor
with a P-port.

Also it remains to be seen if the housings coatings are going to work.
