C'mon Al. The useful part of that email was "two inlets, two outlets". The
rest of it was either lecturing, standard cozy implementation or self
agrandizement.
I did a search for muffler (title only) and found 100+ emails in the last
year. People here are contributing lots to the advancement of the art.

C'mon guys. You do this every time there's a crash. Instantly go into
rationalization mode. It's unhealthy. Greatly increases risk builders won't
take action. Increases risk you won't research it thoroughly.
A healthy response would be:" Here's another example of how our engines
produce unusually destructive exhaust temperature and pulses. We have a rich
history of broken exhaust components. We need to be very thorough when
designing and building exhaust."
I designed my own muffler. It had two inlets, two outlets. So if (when) my
muffler failed, it could never block both pipes. I also put loose safety
wire around my pipes, because on a pusher loosing pipe wipes out prop. So
basically, I assume stuff will fail, then design it to control the way it
fails. I've heard of rotary guys doing same type of thing. This is a good
time to share those key items.
On your car, they deliberately design products to fail a certain way. They
will make a component weak, so it fails first. They do that with wheels and
hubs. So when the muffler fails, little pieces come apart, not big sections?
You guys do a great job of sharing successes, design and construction
details. This is another opportunity.

<No doubt you are on the money, Rusty. When folks are already predisposed
to bad mouth the rotary - this will only be more ammunition. "See! even
with umpteen million dollars you can't get one to fly" {:>). But, I
serious doubt it will effect many who have researched the rotary and come to
understand its benefits - as for the rest, who cares {:>)

I'm certain it was a relief to Mistral that the culprit was not one of
their engine components.
Whew! a close one for sure.
Hi Ed,
Unfortunately, I bet the majority of people will only hear "Mistral
rotary", "lost power", and "crash" :-(
