N492CM flew for the first time Sunday morning. It was
a short flight (.2)—just enough time for one pattern.
The engine was super smooth, and seemed to have lots of
power, although I never really did look much at the dynamic RPM that I
reached. I was busy paying attention to the coolant temperature. The
oil temp stayed below 200 the entire flight. But I took off with water
temp at 185, then with full power and the climb to only 2000, the temp rose to
about 230. I pulled the power back, and basically glided around the
pattern for a full stop. As soon as I pulled the power and dropped the
nose, the temp started back down. When I landed, it was back to 195.
Taxied back uneventful.
I have the small (facial area) thick radiator from Ed Klepeis
(see the pic below). Is anyone else using this one? How have your
temps been? I would like info and pictures on your setup to see if there
is some tweaking I can do to mine.

Special thanks to Tracy for the many phone calls and extra
help. There is no substitute for a great builder assist hotline!
