This is after one martini and into my second glass of wine, but why do I
need to calculate my power?  I'm going somewhere, I climb to 8500 ft.
westbound and 9500 ft. eastbound and I'm at full throttle, 2350 RPM, leaned
to about 50 deg. rich of peak in my IO-320, and when I put the numbers into
my GPS (temp./alt./IAS/Altmtr.) it comes out my true airspeed is usually
around 200 kts.  I put the descent into the GPS and down I go to arrive
about a mile or two short of the runway (uncontrolled field) at about 190
KIAS.  With all due caution and with appropriate radio transmissions, I
arrive over the runway at about 50 ft. (maybe less) and pull up and around
into the downwind.  When I reach the abeam point I am at about 110 kts. so
the wheels come down and as the speed gets below 100 kts. the flaps go to
about 1/2.  Around the corner we go at about 85 to 95 kts. keeping the nose
down, with power as required  and aiming at the end of the runway.  With the
runway made, full flaps go down, power as required to let the speed get down
to 75 or so and fly it down to 1/8 of an inch off the runway then ease the
power off.  Keep the nose up now and the airplane will do the rest.  Keep
the stick back full (aerodynamic braking) don't touch the brakes until the
airplane slows to a fast walk speed.  Taxi in and park the thing and start
answering the questions, i.e. how fast does it go, how long did it take to
build it etc.  Fun.

I don't know how much power my engine is putting out and I don't know if I
need to know that.  It is light, straight, fast and a real beauty and I talk
to it and it talks to me.  Where have I gone wrong?

Larry, I might put a tailhook on this thing.
