For Pete sake.it is kind of like when your wife asks you, "Why do you
love me?".you will get cooked on that question no matter what you say.
When you come to the table with your mind made up you will never
understand the other point of view.
I had a arrogant (sounding) jerk come up to me at SERFI after seeing
the VG's on my wing and ask, "What aerodynamic problem are these on
there to fix?".I just said the problem of wanting it to stall even
slower and more gentle than it already did.
What you fellows saw at the great "test" was 2 different planes, flown
in different configurations, at different weights, at different power
settings.in other words, from an engineering standpoint you saw
nothing!!! The flaps alone can account for a huge increase in max Cl.
If the ground rules had been set beforehand, full flaps/no flaps, idle
power only, load the planes to similar weights, etc. it would have been
in the neighborhood of a valid test, but the true VALID test is flying
the same plane WITHOUT them and then WITH them.no other differences
except the effect from the VG's.
I'LL STATE AGAIN.THE "BEST" TEST OF THEIR BENEFIT IS THE COUPLE OF DOZEN
GUYS ON THIS LIST ALONE THAT HAVE TRIED THEM AND SAID THEY WOULD NOT
TAKE THEM OFF AND THAT IT WAS THE BEST $100 THEY HAD SPENT ON THEIR
PLANE.
If you guys that have NOT actually tried them don't want to then fine,
but DON'T say they have no benefits! Us that HAVE actually tried them
are not stupid...
I have said several times that the improvement is not just a number on
the airspeed indicator but how it "feels" when that airspeed indicator
is getting near the bottom. I will guarantee that the absolute bottom
number will be lower than before, but that isn't the major thing.
I just can't get my head around why you guys are so hell-bent against
something you haven't actually tried.If you try it and can say it was a
waste of time,money,etc. then fine you might have a dog in the fight,
but why do you even HAVE an opinion of something you have NO EXPERIENCE
with? Like the other major "controversy" of the Kolb-list.SEAFOAM.I
never say anything about it, cause.you guessed it .I NEVER HAVE TRIED
IT!!! Sorry, but it didn't interest me!!! Oh well!!! But I haven't had
ANYTHING to say about it, pro or con, because I don't know!!! Nuff
said.

Hey Bob, I noticed that if I loosened the 6 main prop bolts on Warps HPL
hub it
put tremendous presure on the smaller inside bolts.
Maybe I should be replacing mine, although I doubt anything would happen
even if all those smaller blade bolts fell out.

The friction pressure of a prop bolted against prop hub is the primary way that
torque is transfered to the prop. If you reduce the recommended torque on the
bolts the prop bolts could break in shear and the prop might come off. I had
a wood prop on a Weedhopper that would shrink and expand depending on the weather.
One day it got loose and sheared to prop bolts clean off. Later I was told
that wood props need to be retorqued with each change of season or sooner.
Richard Girard is right about the 8mm bolts on the Powerfin. I use some long grade
5, 5/16 bolts that have a higher torque rating than the recommended 175 in
lb or 20 nm but I torque to the prop makers recomendation. I asked Stuart about
using the bolts higher rating once and got my ass chewed just for asking.

| Subject: | Wooden prop bolt torque |
Rick Nielsen brought up an interesting point about bolt torque on wooden
props, that is shrinking of the wood with temperature and humidity. One of
the fellows on the canard aviators forum lost a prop due to this factor and
lost a large chunk of wing in the process. Marc has since been experimenting
with belleville washers as a way to ameliorate the effects of temperature
and humidity. You'd have to take into account that props typically used on
Kolbs have about half the hub thickness of those used on a Lycoming O-360,
but belleville washers (spring washers) are available from McMaster Carr (pg
1165) in a variety of rates and thicknesses, and can be stacked to get
almost any combination of pressure required to maintain a consistent torque
pressure on the prop hub.
Ok, it's experimental aviation here's an experiment to perform. I'll take it
up when I get my Firestar certificated next month, but if there's anyone out
there who's looking for a project, feel free to start without me.

Rick,
You are right about the friction, but I believe what fails the bolts is
fatigue from the bolts slightly bending.
Never had any trouble with my Sensenich 64x79 here in Fla where we have big
changes in temp and humidity. I did however check the torque monthly. After
the first year it seemed to stabilize.

Thanks for the good wishes Dennis.
I am relearning the art of taxying a tail dragger in a straight line. Got
the tail up yesterday and, you wouldn`t believe it, but there is a bump in
the middle of my strip where a hedge was grubbed out and I was accidentaly
nudged into the air. Just for a moment you understand. Actual flying would
be illegal and I wouldn`t want to do that now, would I?
The baggy pockets which I was convinced caused the runaway into the barn,
was aided and abetted by the fact that Jabiru policy is that if something
fails the throttle goes to `Open`. I think the baggy pockets just jogged the
throttle enough for that to happen. Makes me feel a bit better, but not
much. That throttle friction nut is done up good and tight now!
Cheers
Pat

We do have one problem.
Your statement "It was nice to be "Experimental 1782 Charlie" instead of "yellow
ultralight." is incorrect.
Your callsign should be "Kolb 1782 Charlie" all the time with one addition. When
you call an ATC Tower on initial callup you add "Experimental" to the end of
your callsign then omit "Experimental" on subsequent contacts.
See Aeronautical Information Manual section 4-2-4. Aircraft Call Signs.

Roger:
I know what you are going through. I used experimental for years. Then John W
straightened me out. I am Kolb 101AB. Occassionally, I stick experimental on
the end when I go into a towered field.
Congratulations! Now you can stop looking over your shoulder when you fly out
of those "citified" airports. Flying out of Rock House Field, I would not worry
too much about an FAA inspector.

This darn program sent my post before I got the photo of the welcoming committee
posted.
Anyhow, when I was on short final to Gantt Internationa Airport, I noticed the
whole crew was out to meet me. They decided they would wait where I normally
stop the airplane and disembark. There must have been 20 momma cows and babies
under the tree. Some of the calves were probably a day or two old. Got their

Steve, I think you and Rick N. are both right, just looking at it from
different ways. The prop gets loose as the wood shrinks and the torque
pulses of the engine then rock the prop back and forth against the loosened

Works a little different if your system uses drive lugs, like the Warp
Drive.
I very seldom break a prop bolt. One or two since I started flying 912
series engines some time ago.
Question: Would failure in shear and bending be the same? Seems to me
shearing off 6 prop bolts would be tough to do with a wooden prop. Bend
them enough cycles and they will fail.
john h

The prop gets loose as the wood shrinks and the torque pulses of the
engine then rock the prop back and forth against the loosened bolts.
Eventually, the prop bolts fail in shear.

Hi Gang:
Sorry about firing a blank a minute ago.
Every time I would hit reply to Jim's msg, my computer would lock up.
Finally, it burped, and fired off a zero reply to Jim's email.
Anyhow, Jim mentioned loose drag strut fitting bolts and universal joints.
I include these in my preflight and post flight inspections. I have found,
through the years, there are a lot of Kolbs out there flying with the
trailing attach points pretty sloppy. They fly better snugged up. I push
up and down on the inboard rear corner of the wing pretty hard. If it has
slop you will see it move. I tighten up the drag strut bolt through two
small slits in the inboard rib fabric. I have also changed out a bolt this
way. A little tedious, but can be done.
Take care,
john h

That's better than most of the tractor gascolators I've seen... but I was
looking for something with a drain, like I had on my '41 T-Craft.
I now have one of the inline filters with a glass body from the auto parts
store on my Ultrastar... not as convenient, but I can unscrew the ends if I
really need to.

The throttle lever on my firestar did the same thing in flight after only 80
hours. I was able to change throttle settings by turning the hub. I made a
temporary field repair using JB weld and a 3/16" drill bit as a connecting
rod. That was 40 hours ago and I see no real need to change it.
Mine broke off without bending as yours did. If you look at the missing
paint at your bend, it looks to be corroded like it had been bent for a
while?

Those do look nice, but they still lack the combination of features that
seems to be no longer available... a clear bowl so you can see what's
inside, AND a drain valve.

John, Go to Canard Aviators at yahoo groups and read Marc Zeitlin's story.
Lyc O-360's have drive lugs and 3/8" bolts to hold on the prop. Look at the
pictures of what the prop did to the wing and winglet when it departed. It's
a chicken and egg question when you find yourself with a prop one moment and
without one the next.

Does an 0-360 have any kind of torsional vibration dampening, other than
the prop?

John W,
Thanks for the link and the lesson, "Kolb 1782 Charlie" it is. Makes sense. When
I used to fly 172's it was always "Cessna 1556 Foxtrot." Guess I should have
checked the AIM instead of mimicking the locals. I also enjoyed your movies
from the Kolb homecoming.
John H,
Nice welcoming committee. In a former life I used to live on a ranch with 600
pairs of those beautiful Charolais. I fly back there now and then. One must
beware the land mines lest one find oneself with green stripes on the bottom of
the wings. It will be nice not looking over my shoulder on the ramp or doing
360s to wait for the "real" airplanes in the pattern.
Take Care,
--------

No, theres a flywheel to carry a ring gear for the starter and that adds
very little since it's aluminum. Rotax has the benefit of 40 years of
engineering science to make their little jewel work. I didn't really
appreciate what their engineers had accomplished until I tool Eric's class.
Lyc is stuck making adaptations to the technologies of the 1930's. Like the
Rotax, it's a real testiment to the engineering technology of its day.
