Since I've passed the 100 hr mark on my n/a 20B Lancair ES with no
significant issues, I'm feeling more comfortable with its reliability and
performance.  So, I thought I would pass this story on for the benefit of
those still building, and those that are contemplating using a rotary in
their project.
----------------------------------------------------------------------------
Sunday was a beautiful day, not a cloud in the sky.  So, the wife and I
decided to fly to Llano, Tx from Lockhart, TX (78 NM) to have some BBQ.  We
were accompanied by another buddy in his RV-7A, also from Lockhart.  His has
a very nice RV-7A (powered by a custom-built Lycoming IO-360).  He always
flys at wide-open throttle, flying on ahead and landing ahead of the rest in
the group.

Well, I thought that two could play that game, and so once I leveled off
at cruise altitude (4500msl), I didn't pull back on the throttle but kept
the power in.  I was cruising along about 192 mph (I usually cruise at
170-175) and I looked off the left wing and there he was, sneaking up on
me.  So, I opened the RAM AIR, tweaked the mixture for full-power, and
re-set the M/T constant speed prop to bring the RPM's up from "economy
cruise" to "racing speed".  I picked up about 18 mph, which brought my TAS
to 210 (according to the EM-2) and sure enough, when I looked to my left, my
buddy was nowhere to be seen.  The 20B rotary was purring along at 6000 rpm
and could have done it all day long (or until I ran out of gas).  Shortly
thereafter, he got on the radio and started quizzing me about my
groundspeed, TAS, IAS, engine rpm, etc.  Needless to say, I landed first.
Man, that felt good!

I really showed him... fuel burn went from 11 gph to 15.8 gph, but since
mogas is half the price of 100LL, it's no big deal.  However, I doubt he
will make wise cracks about the rotary engine any time soon.  I think
there's a P-port 3-rotor in my future.
