Dear Listers,
I added a new Wiki web site to the Matronics Email List features earlier this year. What's a Wiki, you ask? Well, here's the Wikipedia (http://en.wikipedia.org/wiki/Wiki) definition:
A wiki (IPA: [ w .ki ] <WICK-ee> or [ wi .ki ] <WEE-kee>) is a type of Web site
that allows the visitors themselves to easily add, remove, and otherwise edit
and change some available content, sometimes without the need for registration.
This ease of interaction and operation makes a wiki an effective tool for
collaborative authoring. The term wiki also can refer to the collaborative software
itself (wiki engine) that facilitates the operation of such a Web site,
or to certain specific wiki sites, including the computer science site (an original
wiki), WikiWikiWeb, and on-line encyclopedias such as Wikipedia.
Under the Matronics Email List Moniker, there is now a very nice List-specific
Wiki available! It a place for Listers to put articles about any aviation topic
that suits them. The purpose is to provide what the mailing lists do not:
structure and persistence. The mailing lists are a fantastic resource to ask
a question and get good (and bad and funny and annoying) answers. But once the
question is asked and answered it is not in front of the List anymore. If a
new person subscribes the next day, he/she does not see that information unless
he/she goes to the trouble to search the archives, a hit or miss proposition.
The result is that the same thread of conversation gets created and/or revisited.
There are several things that happen as a result:
1. The person gets his or her question answered;
2. The information gets better as more people think about and answer the question;
3. The people who have seen the same question asked and answered get annoyed
at seeing the same things over and over and over and ...
So this is where the Wiki comes in. You know what questions you wanted answered.
You may have asked or answered the question. You know the information is useful.
So you put the information here, in the Matronics Email List Wiki!
It doesn't matter that this information is 100% complete or correct. Just writing
something creates a placeholder and makes useful information available immediately.
It has the same immediacy as the mailing list but it has persistence
and structure.
But what if the information is incomplete or incorrect? No problem! Anyone else
coming along can edit the article! If I write something and you discover something
I have left out or stated incorrectly, you can fix it right then!
So let's begin and make this the place for information about building, flying,
maintaining, and understanding our airplanes.
But what about whether something is "appropriate" or not? Don't worry. Write
it down. Let the reader determine whether or not it is appropriate. If it is,
he/she will read it. If it isn't, he/she won't. It's as simple as that.
And when you do write that article you won't have to worry about whether some editor
is going to decide whether or not to print it in a newsletter or whether
the webmaster will have time to put it up on the web page.
The last question I hear brewing out there is: if anyone can post anything, won't
this just become a mass of garbage? Surprisingly, the answer is a resounding
no. If you want proof, go visit the Wikipedia, a free-to-everyone encyclopedia
written by whoever wants to write articles. The articles there are as good
as anything I have read anywhere and anyone can add anything anytime they want
to.
So don't hesitate. Write it down. Put it here. It will never hurt anyone. The
more information we get here, the more useful it will become to other people
and the more information they will put here for YOU to use.
Here's the URL to start (there are lots more bured under this starting place):

| Subject: | Re: Kolb Glide Ratio (UNCLASSIFIED) |
Glide ratio = Lift/Drag
Glide ratio at best glide speed is (Lift/Drag)max, or L/D max.
Kolbs (and all ultralights) have fairly high drag for their size. The amount of
lift will be = to the weight, which for an UL is not much while flying (500
to 800# gross weight).
Thus we have a (small number)/(big number), which yields a small number, i.e.,
poor glide ratio.
Jets have a good glide ratio because they are very low drag (no struts, small thin
asymmetrical wing, retractible gear, etc.) and high lift. They are high lift
because they fly fast and lift goes up as the square of speed. Best glide
on the A4 Skyhawk is 320 Knots. You have a great L/D max, but your rate of descent
is 2000 fpm with the gear up. Put the gear down, drop the flaps, and the
ROD would probably drop to 6000 fpm.

No need to wait till then if you want an inspection panel. They can be
bought at any aero store. Just stick the ring on, cut out the inside of the
ring with a sharply pointed knife and slip the tin cap on.
The cap has a short piece of tin across its diameter which is pinned to the
caps centre. It is slightly bowed so that the ends slide inside the fabric
on both sides. The tin cap itself will `spam can` as it is made with a
slight curvature.To open press the middle and it will `pop` . To close press
the edges and it wil `pop` the other way and hold the the whole thing tight.

Hi Dave.
indeed they do. Its about 30 years or more since I flew a sailplane last and
just couldn`t remember the terms. I look at the picture on my den wall now
and there is me in this sleek 19 metre span , shiny fibreglass bird, water
tanks, poitive and negative flaps, retractable wheel, long glass nose with
me almost laying on my back to fly it and I think. Good Grief did I really
fly that.

Hi ,
not too serious. I had it happen a couple of times in my Challenger
which with the high wing pusher position is similar to the Kolb.
When the engine coughed I slowly opened the throttle and that kicked
the ice on through. Never had to land out becauase of it.

I was once flying a powered parachute, at dusk, temperature about 68
degrees, and humidity so high that fog was starting to form. 503 engine
suddenly coughed and died. Couldn't be restarted. I landed unpowered in
the nearest hayfield. No problem. Tried to restart the engine shortly
after landing. Started just fine. Figured I must have had a seizure, so I
opened the engine up. No sign of a seizure anywhere. Figured it must have
been carb ice (most likely explanation).
I solved the problem by buying an electric carb heater (Cyclone) It was an
electrically heated ring of metal that fit around the throat of the carb
air intake, and warmed the metal enough to prevent ice crystals from
sticking. Ran off the 503 electrical output. Never had an another engine
failure. Very nice gadget.

I fly the best looking plane there is, a Kolb mkIII.
My mkIII is also self launching, gives me the option of when and where
I want to land, and allows me to go-around if I screw up my landing.
All the while being mighty purty!!!

Just curious, what would I look at in my MkIII wing if I did have an
inspection port?
At least once a flying season I shake the wing tip up and down and
listen for
unnatural sounds. As it is I'm happy that no critters or nesting bees
can get in there.

Subject: Kolb-List: Looking for a Kolbra or Slingshot
My name is Richie Mattson and I live in Duluth MN. I tested out a
Kolbra recently and really enjoyed it's flight characteristics. I am
interested in finding one for sale in the mid 20's with a 912 or one for
less with a 2-stroke that I could replace. If you know of one for sale
or someone who is considering selling, please give them my number.
Also, I have seen some postings regarding the Slingshot. Could
someone fill me in on the differences between these two models. Maybe
the Slingshot would work for me as well. I see that there is one for
sale in PA. I hope to find a plane and have it ready for winter ski
flying by the time snow flies. Also, I would really like to take it to
Sun n Fun this April. I really enjoyed my trip to Oshkosh the last 2
years in My Aerolite 103 but need to upgrade for longer trips.
I have been reading the list for a few weeks now and like the hutspa
of the members and their zest for life. I hope I can make this happen
so I can meet some of you at the fly-ins around the country. The wife
has already resigned herself to the fact that I have found a new
adventure to pursue so at least the main hurdle is cleared. Now it's
down to finding and/or building the right plane. Let me know if you
locate one. Thanks for the help.
P.S. Hi to John H. It was great talking with you at Oshkosh last
summer. Thanks for turning me on to the Kolb.

| Subject: | Re: UltraStar Value? |
This is just my opinion, from being a Kolb owner for 10 years and wanting and
pricing Kolbs for years before that.
$4,000 to $5,000 is a fair price for the Ultrastar. It could be worth more if it
was a show plane and less it it had any problems. But based on the photos, it
seems to be in good condition, and I based the price on that.

Here is a technical question. I love my Mark III Classic. BUT, it is
noisy. I use a Geo Metro engine which is great, but still noisy. I
have heard that if one cuts a slot in the after part of the exhaust, it
will be quieter. I now get 270 lbs of thrust at 5000 ft density
altitude which is about 325 lbs at sea level. I will be trying this
slot soon along with a thrust test to see if there is a difference in
noise and in thrust. Has anyone ever tried this on a four cycle engine?

My experience in sailplanes is limited. The Grob 103 is slick and easy
to fly and stays up with a real good glide ratio. The Schwitzer 2-33 is
a dog, but fun to fly. The most fun and easiest to fly was a PW-3 which
has a glide ratio about in the middle of the Grob and the dog.. But,
all of them required some altutude to operate in and so the beauty of
low level flight is lost. I love my Kolb except for the noise. I am
thinking of building a flying trailer and putting the engine back there.
