Dear Listers,
As of today, contributions to the Matronics List Fund Raiser are lagging behind
last year at this time by 21%. I have a fund raiser each year simply to cover
my operating costs for the Lists. I *do not* accept any advertising income
to support the Lists and rely solely on the contributions of members to keep the
expenses paid.
I run all of my own servers and they are housed here locally, and the Internet
connection is a commercial-grade, T1 connection with public address space. I
also maintain a full backup system that does nightly backups of all List-related
data so that in the event of a server crash or worse, all of the Lists and
the many years of List archive data could be restored onto a new server in a matter
of hours.
All of this costs a fair amount of money, not to mention a significant amount of
my personal time as well. I have a Fund Raiser each year to cover these costs
and I ask that members that feel they receive a benefit from my investments,
make a modest contribution each year to support the continued operation and
upgrade of these services.
If you enjoy the Lists, please make a contribution today. I also offer some incentive
gifts for larger contribution levels. At the Contribution Web Wite, you
can use a credit card, Paypal, or personal check to show your support for the
continuation of these services:

Thank you for your support!

Steve,
I put mine up the wing struts on the upper side.
You hardly notice them except when you are getting in and out.

Does anyone have a suggestion on where to put the 2" EXPERIMENTAL
placard on the Kolb Mark III classic I do not want to put them on the
fabric? I am thinking about putting them on the outside of the cabin
doors at the bottom.

thumping with the panels yielded a different pitch from left wing to right.

Hi
What a great idea!. We can now tune our wings so that they vibrate in unison
or in harmony. If we add in the tail and rudder we could get a full five
note chord.
I think I shall go for a F9th aug 5th.
Instead of arguing about VG`s we can now have a brand new thread, never
before discussed.
For starters, should all Firestar wings be tuned to the same note?. Maybe a
third above a Mark 3 which would naturally have a little more bass in it.
Could we tune them so that a formation fly past, say at Oshkosh, could
reproduce the the opening of Beethovens 5th.. What prospects unfold before
us !!!!!

Well,this probably isnt Kolb related ,since it is an Ultrastar,but I
will
put this out anyway.
My ULTRASTAR has flown without the filler between between the center
section
for 60hrs+ since April. I have not noticed any loss of control at
stalls or
in any other flight position,including landing....plenty of room to
flare.
I installed a velcroed gap filler with an alum. flashing leading edge to
give it stiffness,instead of using a center rib of sorts.
The takeoff-climbout seemed a little faster,but what really seemed to
change was the pitching up of the nose at cruise
Originally I needed to install a bungee to hold the stick back(John H
trim)
which worked great. I now have to push FWD at level cruise(75%). Just
trying to figure out why it changed so much
On the flip side,I can putter at 3200 rpm and sink about 80fpm or
so.Havent
dead-sticked it yet,but will try it as soon as the weather changes.Got
10+
in so far,so I have a good reference point.

Bob
It seems like when I was covering my airplane I read in the polyfiber
instructions that the use of a heat gun would damage the fabric. They go to
great lengths to have you calibrate a iron and warn you to not exceed a
maximum temperature. Seems like they say that a heat gun would too easily
exceed the maximum temperature. You may not have damaged anything, just
wanted to advise everyone this isn't the recommended method of shrinking
fabric.

Dude - last I heard, Ultrastars are Kolbs - no problem.
Shooting from the hip here, perhaps having the prop below the trailing edge of
the wing keeps the airflow from exiting the gap to the extent it would if the
prop is higher, thereby reducing the normal loss of lift. And the stick bungee
worked the way you would expect.
Now that you have a gap seal, the loss of air through the front part of the gap
(where the prop draw would not have as much effect) is reduced, giving you a
bit more lift at the forward part of the wing, changing your apparent center of
lift forward. Now you have to hold forward stick to compensate. In any event,
your center of lift has moved forward.
Not sure if this is right, but that is how I am visualizing it. And as Beauford
says, Worth what ya paid fer it.

Mark,
Just to add a little to what Richard wrote. By closing the wing gap, you
have increased the effective length of your wing. For the same thrust or
throttle setting, the wing will generate more lift. To maintain level
flight, you must hold forward stick and reduce the AOA until the wing
generates the same total lift as it did with out the gap seal. If you are
holding an uncomfortable amount of forward stick, you may need to adjust the
horizontal stabilizer AOA.

| Subject: | Metal fuel pickup from TNK |
Dear Kolbers,
Since my engine quit in flight due to bad polyurethane material in the pick
up interface line, I learnt from some of you that an =9CALL METAL
=9C fuel pick up is available from our good friend Travis at TNK.
I ordered the same for both the tanks and found it really good. The fitting
is soldered to SS tubing and the whole line can be slid through the rubber
grommet, into the tank.
Surely some peace of mind during flying :- ))

Ummm, Rick, I was only offering a solution to remedy an imperfect situation,
not advice on how to cover a plane.
BUT, since the cat is out of the bag, lots of planes have had their dacron reduced
to the dimensions allotted with favorable results.
A heat gun with a diffuser on the end would be a help in reducing spot overheats.
The gun does better than an iron in shrinking large panels to a light fit. Damage
would not be easily done at this stage.
Final tightening can follow using an iron.
If one is concerned about strength, the cabin area would be an excellent candidate
because strength is not a factor.
Old bedsheets would suffice.
The place where the iron excels is slightly lumpy areas around curves and tubes.
Especially good for taking wrinkles out of
surface tape.
BB, good day, bowling with fellow geezers, hiking the back fields with my recent
adopted pal, a toy fox terrier.

Whaddya talking about? An UltraStar is certainly a Kolb!
I posted on this a few weeks back after flying without the gap seal for the
first (and last!) time. Bottom line is that the plane handled very mushy,
needed a lot more back stick to lift off, and the rate of climb was
drastically reduced.

Hello Kolbsters,
Has anyone ever seem a belly fuel pod on a Kolb. I was fly moose surveys
today, and most of the Supercubs we charter have belly pods. The plane I was
in today can carry 36 gallons in the pod, the fuel is transferred in to the
wing tanks once enough fuel in burned off. A smaller pod for a Kolb could
carry a couple hours for of fuel.
Thanks to Rick for doing the math on the "Starved Horse Wing"!
