I finally got a great day to fly and nothing I had to fix.  OAT - 30F,
Wind - 0. Only hindrances were the snow drifts on the taxiways.  I had
to dig my way out twice when I got a little too far off the path
scraped clear by the city.

I checked the Hobbs as I lifted off, 9.5.  After flying around for a
while getting a feel for the plane at different power settings and
doing some turns I noticed the Hobbs was 9.9.  Flew some more and the
Hobbs was 9.9.  Huh! it must have just clicked over last time I
looked.  Checked my watch and five minutes later the Hobbs was 9.9.
Well crap, how long have I been flying?  I transferred some fuel to the
main tank just to be sure I had plenty. (The fuel gauges work but are so
non-linear I haven't learned what any particular reading really means.)

Uneventful landing and I was sort of expecting it to be OK, i.e. I
wasn't as nervous as I was for the last two.  Now I've got something to
fix.  I got a good time for TO from the video camera and it turns out
the flight was exactly 1 hour.

I'm still seeing around 7500 rpm at TO, 100 mph and 1000 fpm climb.
Today I flew enough to find that I can run around 6500 to 6800 rpm and
keep the temps below 200 with IAS of 130 - 140 mph. And I can maintain
level flight at 100 IAS at about 5500-5800.  I'm going to have to try my
ground adjustable Warp Drive prop to see what kind of performance I get
running with a little more bite.
