Martin,
I'm here in Nashville but have no idea how to find these
airports you mentioned. I will be out driving around the
area and hope to get up to the Clarkesville area today.
Please call me on my cell phone at 704-661-7899.

Hi Gene,
I have to assume you are using Netscape.
When running Netscape to view my website photos, you have to change the " \
" to a " / " just before the photo file name. When you use Microsoft
Internet Explorer browser, it loads right up.
For some reason Netscape changes my last / to a \ . I do this for fun so I
don't know why it happens.
Here is a sample photo:

I am in the process of changing the classification of my aircraft from
"Ultralight" to "Experimental". I have applied for and received the "N"
number. I'm getting ready to apply for the Airworthiness certificate.
FAR 91.9 states that I need a "FLIGHT MANUAL".
Does anyone have a Flight manual that I can use as a reference so that I can
make one up for my aircraft!

John,
I just reviewed FAR 21.191 and didn't see anything about a flight manual
for experimental aircraft in the airworthiness form.
Anyway I don't have one, never seen one, and the inspector never said
anything about one, but if you find one, I would like a copy. Maybe it
will help me fly better.

Richard,
I have been using 5/8" ID high temp silicone tubing over my springs to dampen
them for about 170 hours now. I still safety wire them but I haven't had one
to break yet. The tubing is available through model airplane suppliers, it
is used to couple a tuned pipe on an RC plane.

My Kolb friends using Netscape:
I have mad the proper changes to the links to all the photos on my website so all
the Netscape users should be able to see the pictures now.
If anyone has any problems with links, I would sure like to here about it.

--> Kolb-List message posted by: "Richard Swiderski" <swiderski@rocketjet.net>
Kolbers,
I've been re-doing my website, http://www.geocities.com/ib2polish , &
thought a portion of its text would be of interest to those who might be
thinking of "going out of the box" as far as using alternative engines is
concerned. If you want to see the torque curve, go to MY KOLB; then to
ENGINE; then to ABOUT ENGINE. It over lays the Suzuki's curve with some
Rotax curves. below is an excerpt.
Richard Swiderski
SlingShot/ almost TuboSuzuki / Florida
ENGINE DATA
Naturally Aspirated:
This engine is ideally suited for aircraft use. Its most outstanding
attribute is its torqu curve. It is virtually flat throughout its operating
range. The Suzuki's 4-stroke, 3 cylinder, one-liter engine is called their
model G-10. Naturally Aspirated (NA), the G-10 at 3500rpm has 60ft-lb & at
5800rpm it 55 ft-lb. The question everyone is asking is, "Can it replace my
Rotax 582 two-stroke?" Since HP = Torque X RPM / 5252, we can compare the
useful power of both engines very nicely. So as not to be comparing apples
to oranges, we'll use % of maximum operating rpm. At 100% throttle: The
Rotax 582 has 6400rpm/52.5ft-lb/64hp; & the NA G-10 has
5800rpm/55ft-lb/61hp. At 75%: The 582 has 4800rpm/45ft-lb/41hp; & the NA
G-10 has 4350rpm/60ft-lb/50hp. At 60%: The 582 has 3840rpm/38ft-lb/28hp; &
the NA G-10 has 3480rpm/62ft-lb/41hp. The bottom line is: The G-10 has a
32% more power @ 60% throttle; 18% more power @ 75% throttle; and 5% less
power @ 100% throttle. So att full throttle, the 582 will slightly outclimb
the G-10 but at cruise, the 582 is left in the wake! The above formula
works amazingly well. If you take my computations & compare them to the
factory you will see they match perfectly. At 2gph in cruise, The G-10 has
less than 1/2 the fuel consumption of the 582. On a 4 hr trip that amounts
to at least 48 lbs of fuel, which more than compensates for the slight
increase in engine weight.
As per issue 37 of CONTACT! magazine, Steve Parkman had a NA G-10 in a
Jenny replica. Because of the prop diameter his engine was limited to
4800rpm. He dyno'ed the motor in 3 configurations & got 51 hp @ 4800 with a
carburator and 53 hp @ 4800 with Throttle Body injection. He got 64 hp with
port injection, but did not specify @ what rpm (probably at 5800).
TurboCharged:
The G-10 Turbo is were things really get exciting! I have not found
any published performance curves for the turbo version. All manuals agree
that it has a peak torque of 107 ft-lb at 3500rpm. For max HP I've seen:
70hp; 80hp; & "Not Available". The HP ratings don't jive. As we seen
above, torque & HP are mathematically interchangable. So we know for sure,
that at 3500rpm & 107ft-lb of torque, it is producing 71hp. From another
approach, we know the NA port injected version gets at least 64hp at 5800rpm
& the turbo G-10 has 8.7 lbs boost @ 5800rpm which is 59% above one
atmosphere, and 1.59 X 64 = 102hp. The conversion aftermarket rates this
engine from100-115hp. If we use the rule of thumb that an engine's peak
torque is close to its max HP, then it would make about 107hp. If we
extraplolate off the NA G-10 torque curve we get the following for the Turbo
G-10: 60% = 5800rpm/95ft-lb/105hp; 75% = 4350rpm/104ft-lb/86hp; 100% 5800rpm/95ft-lb/105hp.
If we compare this to the $12,500 912S we get: 60% 3480rpm/84ft-lb/59hp;
75% = 4350rpm/91ft-lb/75hp; and 100% 5800rpm/89.2ft-lb/99hp.
Translation: This obscure little engine outperforms the premier,
"100hp" Rotax 912S by 17% @ 60% throttle; 13% @ 75% throttle; and 6% @ 100%
throttle. Obviously, the standard "80hp" 912 is not even in the same
league. This Turbo G-10 is a torky little beast! But that's not all... The
Turbo G-10 can do this at a comparable weight (170 lb vs the true all up
weight of 168 lb for the 912); it has better fuel economy; can cruise at a
lower/more comfortable rpm; and best of all, you can go to your local
AutoZone and rebuild it for $500. You can not bore a 912 jug. Guess how
much money one of those four Rotax jugs cost? Hint: More than a G-10
rebuild.
What about reliability? How does it compare? Well its a no brainer
(In my opinion) compared
to the two-strokes. There are hundreds of G10's flying, many with over 300
hours. I know personally of one with over 500 hrs used as a trainer. The
owner loves it & said all he does is check the oil & turn the key. If you
compare the Turbo G-10 to the 912S, well there are maybe ten of the Suzuki's
flying, and many hundreds of the 912S's. The 912's certainly have a good
record and a long history. However, if the "it takes a beating & keeps on
ticking" track record of the hundreds of thousands of G-10's in abused
auto's (that routinely get 150,000 miles, and whose turnpike speeds are
comparable to aircraft rpms) are any indication, then an 800-1000 hour TBO
is quite reasonable. 500 hours is 5-10 years of flying for most of us, and
if just changing the oil and plugs during that time is all that's needed,
then for the cheap price of an overhaul, even a 500 hr TBO would be
acceptable.

One night while you were sleeping, one of the world's best light aircraft
engines mysteriously got better!
"TBO for the 912 and 912S series engines was increased from 1200 to 1500
hours"
(Reprinted without permission from Experimenter Magazine, July 2003 Page 5)
How does this happen, all by itself? Maybe the only thing they could find
to improve was the TBO! ?
