Chris,

Way to go!  It sure is nice to hear the purr (roar) of the rotary
after many months/years of hard work.  Keep it up... actually flying
behind a rotary is even better.

The folks at LaGrange, TX have a monthly BBQ fly-in, and yesterday was
the weekend.  It was a brisk morning, but clear and calm.  As is the
custom, a bunch of us flew down from Lockhart to eat some good BBQ and
talk airplanes.  I was alone in my Lancair ES, just enjoying the
smooth, clear, calm air.

On the return flight, I was cruising along at 175 TAS (mph) and
4500MSL and decided to see what she would do.  Normally I cruise along
at 4800-5000rpm, but with the M/T electric prop, I have the option of
selecting engine rpm by changing the prop pitch.  So, I cranked the
pitch to where the 3-rotor was purring along at 6000rpm and waited for
things to settle down.  After re-trimming a number of times to keep it
at 4500msl, the speed gradually increased from 195TAS, to 196, 197,
198, ... and finally settled in at 203TAS (per EM-2).  That was too
cool.  I had selected the ES for its (advertised) cruise speed of
200mph, so this confirmed it that the rotary is putting out the power
to match their numbers.  Higher altitudes and with the ram-air open,
I'm confident that it will match Lancair's "advertised" top speed.
What a great day it was!

Keep building Chris, your day will come.
