First of all, Hi.  This is my first post to flyrotary.  Looking to build a Cozy IV with a Mazda rotary.

I'm curious what experiences any of you have with the aluminum housings that are offered in the marketplace right now.  I know that a set is somewhere in the neighborhood of $5000.  But is anyone flying with these things?  Does anyone have a high mileage car or a high time race car with these things or do we know of any not associated with the manufacturer?

The manufacturer is essentially selling roses that need no water and never wilt.  There is no downside to these things - except cost - if you listen to them.

I'm looking for a bit of reality if anyone has some to offer.
