A big success. We had about a dozen attendees off and on.
Jerry Hey and I flew over in the 182 and Chuck Dunlap  flew in 
from Stafford AZ in his rotary powered RV6.

Tom Parkes lives in Prescott and showed his turbo 3 rotor Lancair
ES near ready for first flight.
We successfully instrumented and tested  Chuck Dunlop's airplane for 
cooling system aero pressures. Also I got a noise reading
of about 112 Db about 30 feet off to the side at full runup.

The pressure taps were located as follows with the pressure indicated
at 120 MPH. All pressure relative to Chucks air data system static pressure.

----------------------------------- Inches
#1 Right side behind water rad.     +1 
#2 Right side in front of water rad +6 
#3 Right side outlet of oil rad     -2
#4 Center in lower front of rad     +7
#5 Center in upper front of rad     +3.5
#6 Left side behind water rad.      +1
#7 Left side outlet of oil rad.     -2
#8 Oil cooler intake.               +7.25
#9 bottom of fuse behind cowl flap  -4.5
#10 cockpit pressure                -2.5

Chuck did an excellent cooling systems job. His rad is
rather small. I forgot the exact volume value and it is almost
working well enough under all conditions and conditions in 
Arizona can be real bad in the summer. There is a bit of potential
for more even distribution of pressure over the
face of the water rad. Also the cowl pressure could be
a bit lower judging by the -4.5 inches behind
The fixed cowl flap.  We did not check the pressure distribution
on the front side of the oil cooler as it was too hard to get
too. Outlet of the oil cooler looks real good at -2 inches both sides.
Main inlet to the oil cooler is also as good as can be expected
with the +7.25 being near full dynamic pressure for 120 MPH.

This is the best results that I have measured so far.
Chuck feels he needs a bigger rad as he is down on power
probably due to an over pitched or too large in diameter prop 
as he is seeing only about 5800 RPM.

Jerry got his first ride in a rotary powered airplane and took 
the measurements in the bargain. Here is Jerry, Chuck and the water 
manometer squeezing into the RV6 cockpit.

Chuck also kindly gave Tom Parkes a ride.

Tom also did an excellent rotary engine installation job and some pictures
on this later.

We buzzed 379 miles over there in the 182 at up to 190 MPH gps with a strong
tail wind. Coming back we paid the piper at 120 MPH gps.
