Hi- not sure if this is the correct email address,
  but would like to find out more about the aluminum rotors?

  Since somebody let the cat out of the bag at SevenStock-2010
  this is an indication of what you are going to have
  to deal with Jeff & Dave :)   What is the status of the test
  engine?

Are you guys familiar or aware of RX7 Specialies.com  They are out of
Calgary,AB. I just looked and he has aluminium housings to build all aluminium
three and four rotor engines and mentions AC use. With Jeff's Al rotors, a
very potent engine could be built.

They could be reselling Racing Beat aluminum end housings.
The 3 rotor housing looks new.

That 3 rotor center housing looks interesting.
What it looks like to me it is made in two pieces
on an NC mill and sealed with O-rings. Looks like
a good idea. It all hinges on what kind of wear
coatings they are using.
