I stopped off in Michigan and met C. Smith at
his hangar. He is building a P-port rotary powered Zenith 601.
Here is a shot of his square tube exhaust manifold.
This will be the start of a tangential muffler.
Note the English wheel. Brian Trubee will not have the
only aluminum cowl :)
C. Smith came up with some cute Minihelc pressure gages.
These are super sensitive at only 2 inches of water full scale.
I was unaware they made them this small.

 No way dude that is twice the HP and twice the weight than what
that plane is made for and it will take a 50lb chunk of lead in the
tail to put it in balance, I am building Zenith 601 and I have
1500hrs flying time in my rotary coot but for the Zenith I am just
going to bolt on a 0-200 and go fly as I am done experimenting.

I made a mistake Ken. It is a 605.

Let us know how that O-200 works out for you :)
I'll bet you won't see 1500 hours with out some
valve work. I think I only average 500 hours with
out some valve work on my O-470. Of course I cannot legally
do the work myself so it gets expensive.
