Having "finished" my plane and signed off in January, I've been
tinkering
with minor improvements, engine tuning, and building up my own flying
currency ever since.  Just about the time all of that came together
the
infamous Pacific Northwest weather socked us in and it looked like it
would
be weeks, months, yea even years before I could do my first flight in
N31CZ.
Well we got a temporary reprieve and today was the day! At about 8:45AM
PDT,
N31CZ defied the laws of physics and actually left the hard but
comfortable
surface of our planet!

The Mazda Rotary, 13B (non-turbo) engine worked fine. Not great, but
fine.
Temps were in the mid-170's for both oil and water the whole time.
(Outside
air temp was 35F-40F). But power was a little anemic, so I'll still
have
some tuning to explore.

ADD ME TO THE FLYING Rotary LIST!!

Congratulations Joe. Got any pictures of the installation?
We are always on the look out for pictures.
For example what does your cooling system look like?

Yes, Congratulations Joe.  This is a 13B non turbo.  but not a pport?
does it have porting? IE.. Bridge porting etc...
T.W.

It's not P-Ported just "Mild Porting" by David Atkins. David Atkins said he
would come up and check out my tuning too. So, that will be a big help
confirming my power (or lack thereof).

Thanx,
