Hey Paul, don't give us more work than we already have!

You surely know that Norton/MidWest/Diamond's technology of air cooling the
rotor(s) seriously limits the maximum power output of these engines.  It
seems that it's fine for single-rotor models but not for 2-rotor ones.

As you know Diamond has discontinued the production of their 2-rotor.  I
believe they have 40 or 50 unassembled engines and are willing to sell them
as such. I didn't know Christian Dries had a problem with selling to
Americans... (BTW, we certainly don't! :-) ).  But I am sure there is a
practical way around this problem for whom is really interested.

Best regards to all,

Hey Francois, how is your foot healing going? Hope you get well soon. Fixing the air
cooled rotor was one of the suggested changes I would make. That and the roller
rotor bearings. I would convert it into a miniature Mazda with a oil cooled
rotor and with pressurized plain bearings. That should up the RPM close
to 10,000 and add 50% to the HP.

I do not know how old the post is regarding the air cooled two rotors.
Can you tell me if the unassembled engines are still available, or if the entire lot must be purchased in one lot?
I am interested in one or perhaps two of them; we need some information, some internal parts, etc.  I do not know Diamond, and do not know how to get in touch with them.

We are working on a radical new rotary design, but it is too early for any real information.  Perhaps by mid-2005 we can let you know something....
