Kolbers,
Yesterday, I flew a little cross country from Winchester to just south of
Nulltown to a little ultra-light field tucked in between a line of trees next
to a river. They have a yearly hog roast. When I parked I was next to
another Kolb. It turned out to be Dick Graham who hangars at Green Acres
next to New Lebanon, Ohio and a member of this list.
My wife drove down, and we had lunch. I had a great time talking to a
couple of fellows who are in the building process. It is an interesting
little strip, in that you always land to the north up hill and take off to
the south downhill. The trees pretty well blank the wind until you fly
beyond them or up over them. Stayed until 2pm and then headed back home
through the thermals.
The following is from my flight log:
September 6, 2008 - Flights 708 & 709 - one hour, 56 minutes, 46 seconds -
252:28 tt, Victor 1+ 172:28 burned 3.60 gallons for an over all fuel burn of
(at) 1.85 gph. Flew from I22 to 73II, Nulltown, 43 miles point to point.
Louise drove down to carry gas. Had lunch and flew home. On the way down I
had a tail wind and cruised at 5,200 rpm. Burned 1.5 gallons in 48 minutes
12 seconds for a 1.87 gph fuel burn. On the way back I ran the engine 5,200
rpm, burned 2.1 gallons over one hour, 8 minutes 34 seconds for a 1.84 gph
fuel burn. Averaged 23.8 mpg overall, and 28.7 mpg going, and 20.5 mpg
coming back.
Before leaving, I installed the new valve, and new gage. I did not have the
gage converted to a differential manometer so I plugged the high pressure
line so that the throttling valve out but still referenced the pressure
under the wing at the root tube. The gage showed a couple inches of water
right away at low engine speeds with the valve wide open???. The indicator
needle was a little nervous but I believe that was due to the fact it was
referencing cockpit air. If this continues, I will add a critical orifice
to the inlet. I ran the EGT1 up to 1,300 degrees F and EGT2 ran about 50
degrees F higher. Flew at 1,000 to 1,500 in 55 to 60 degree F air to keep
the coolant temperatures below 180 degrees F. I left Nulltown, at 2pm and
so I had a rough ride home. The engine ran well at all cruise speeds. Upon
landing, I opened the throttling valve to richen the mixture. More tests
must be run to see if this is necessary. Very little to no ETG increase due
to nosing down and unloading the propeller while in thermals. The only
difference I noticed in switching vacuum sources it that there was a marked
change in engine idle. The bleed air in the throat leaned out the idle, so
that minimum idle is below 1,800 rpm. Engine did not quit upon throttle
closure. I had to use the grass runway, at I22 because they are working on
the asphalt runway, sealing etc. Landing at Nulltown is always interesting,
as it is up hill and in between trees. Today landing was into the wind, so
one could get the speed down. Departure is down hill, and when you come out
from in between the trees, it gets interesting.
Brought the new gage home so that I can lighten and change it into a
differential manometer. Need to run more tests. This is very
encouraging.
Fly safe!

Hi Jack & List,
It was nice meeting you at Nulltown. Wish you could have stayed longer. Your well detailed and documented experiments are greatly appreciated in lieu of the normal subjective results or pure hear-say often presented on the net. So, in the spirit of accuracy, I have to make a small correction to your report: I'm hangared at Dahio (I44) not Green Acres. Been there since 1985. Feel free to drop in sometime!

Dick,
My apologies. I had you pinned on a map and I read the listing incorrectly.
I would have liked to stay longer, but my wife who drove down needed to get
home. She is one of the working retired folks, and she had a rough week
traveling etc. If she had not suggested that I fly down, I would not have
come. She needed the rest. Also, we built a new home here, and I am still
smoothing out and planting grass seed. Planted a bunch and it has not seen
rain yet. So I water for two days, and then I have a day off. Saturday was
not a day off.
It is great to get out to be with others who enjoy building and flying small
planes. There are two hangars here at I22 contain very small aircraft, but
I never see them fly. I belong to an EAA Chapter down at Hagerstown, but we
only meet once a month, and there are not very many of us.
I am converting the vacuum gage I had in my lap to a manometer, and I have
designed up a mounting for it so it can be attached to the upper left of the
windshield bow. Once it is mounted, and a few more test flights completed
to check system performance, I want to start making some little cross
countries so that I establish fuel flow rates for a given EGT and rpm. So
there is a chance I will come your way.
It was nice to meet and talk with you.
