Thanks Steve,
That puts me up to date on their parts progress,
it will be a mammoth job replicating the Mazda parts to provide the audit
trail necessary for certification. Personally I would think periodic
destruction testing of the Mazda parts to be sufficient - but that may
sound too logical for FAA, unless their doing that in the interim.
If Mistral bought parts directly from Mazda
Japan, I'm sure there would be sufficient audit tracking for the certification
process. I know Mazda won't get involved in the certification process - which
is a real pity IMHO.
Thanks again for the info.

George,
My engine is a hybrid of Mazda and Mistral parts. The rotors, rotor
housings, and intermediate housing are Mazda. Both end housings, PSRU
and oil pan are Mistral. They are using Mazda parts at this point of the
certification under a temporary agreement with the FAA. They are still
in the process of developing their own parts to replace the Mazda parts.
As for the muffler, I agree, the packing will not last. I've spoken
with the folks at Burn's Stainless and they are now using a stainless steel
fabric in the mufflers they provide to rotary racers. I will have mine
changed out at my first opportunity.
Best Regards,

Steve,
Very nice, very smooth and strong, the muffler
doesn't sound too loud, however I don't expect the packing to
last.
Mistral do make good stuff, but expensive. I'm
wondering if their using Mazda parts on this engine or their own parts
developed for certification.
The plane look ready to launch itself into the
air with those high RPM runs - what static RPM do you achieve with the
Mistral engine.
If you can provide any info it would be
appreciated.
I can understand your frustration.

Here
is a link to my latest engine start. As many probably don't know,
I'm not nearly as smart as most of you, so this engine is a full-up
Mistral 2 rotor, their first in the field as a matter of fact. It is
normally aspirated, and has a Burns Stainless 3" x 17" muffler with
stainless scrubble packing. The muffler is not terribly effective,
but I'm going to stick with it for now.
The airplane is basically ready to go, but my airworthiness
certificate has been delayed because the Van Nuys FSDO has arbitrarily
banned experimental flights from my home airport, Santa Barbara.
I've got the national EAA working on the problem, but, for now, I
wait. I thought you-all might like to see this.
