Thanks John, Wish you had taught me that theory when I was back in high
school. Had an ugly girlfriend. Who knows how things would have worked out.
Sorry, Couldn't help it. I think this is a common phenomenon. Not sure why,
maybe our engine Gurus can explain it. I have seen it on everything from model
AC to my 4 barrel Holly on my Jeep. On my FF 447 the clear plastic filter
bowl is always full of air with bubbles from the fuel pump to the carb. I always
assumed that the float bowl was responsible for leveling out the fuel and
filling in the gaps kinda like a capacitor in a circuit.

To All,
I Finally got my house cleaned up and on the market. The house and land at
the new base is cleaned up but needs rebuilding and additions to be a first rate
operation. As soon as the old house sells I will have the cash I need to
build everything at once. Bryan Melborn and I will be staying there during Sun
n
Fun so let me know if anyone wants to check it out. Not planning on breaking
ground on anything until after the show.

Ed,
My Firestar 2 has a lexan tab attached to the right side of the rudder covering
2 rib bays, has 3 on the outboard angle and 2 on the attached angle. It is
bent to the right thus pushing the rudder to the left (if you are looking at the
plane from the rear). My Kolb was built by Brian Milburn, who I believe most
would agree has a stellar reputation for building quality Kolb aircraft.
If you need rudder deflection to the left, to me it makes most sense to have
the tab on the right side of the rudder, thus "pushing" the rudder to the left,
spreading most of the load along the trim tab itself. With the tab attached
to the left side of the rudder the tab would actually be "pulling" the rudder
to the left and placing most of the load against the attach rivets. But then again,
the load amounts might be so small that this is not an issue. My guess is
that the key point is to attach the tab to the side of the rudder opposite the
trailing edge tube.
I do have a Kolb Trim Tab document dated 10-96 that does show the tab attached
to the left side of the rudder bent to the right. But in this drawing, the trailing
edge tube is on the right side of the ribs, thus making the best installation
point the left side. My plane the trailing edge tube is on the left side
of the ribs, so the tab is best mounted on the right.
Well thats just my .02 worth, and in this case, you are probably not even getting
your monies worth! :-)

Group,
I am left with no choice but to put a trim tab on my rudder. Problem is
the factory put the ribs on the right side of the rudder as viewed from the
rear. I need to make the rudder move to the left substantially . That would
involve putting the 2" portion of the trim tab on the left side of the rudder
while the 3" portion which is roughly 30* would be on the right side in order
to push the rudder to the left. There is not a rib on the left side to put
the rivets in. Is it OK to mount the entire trim tab on the right side where
the ribs are. I will have to put the rivets on the right side instead of how
Kolb shows it. Hope I am making sense . I just dont think I have seen a trim
tab mounted on the same side as the angled part.

Having the fuel pump lift the fuel from the tank naturally reduces the
pressure causing some of the more volatile constituents of the gas to
"boil" out. Cures: 1. JH's opaque line, 2. pump at tank level, 3,
slightly pressurized tank, 4. larger diameter fittings at tank and
larger diameter hose will slow the rate of pressure drop and perhaps
lessen bubbles.

Thanks for the reply.
The only reason I know of the existence of the bubbles is that I went
looking for the cause of the fuel alarm. Otherwise my entire fuel
system is made of AN fittings with alum. tubing or neoprene fuel line
with fire covering. I disconnected one of the carburetors to connect
a clear tube.

That is the same drawing I had . I think I will make a tab out of

This could explain why I have had the alarms only recently. I use

Trim tab, trim tab, trim tab. Put it on the right side, bend to the right to
move the rudder left -- reverse for opposite. They've been used since the Wright
brothers flew.
Don't complicate a simple problem.

Just my opinion after having used dozens and dozens. Trim tabs to be optimized
usually need to be fine tuned by the very smallest bend. Lexan is springy and
I'm afraid you will be making an awful lot of flights to get the minute adjustment
needed. Thin aluminum works best for me. If I need an extra long one, I
cut narrow slots in it and bend each segment individually rather than ann at once.

1/16" (.0625) or 3/32" .09375) Lexan will work fine for the tab.

I did not have a good measuring tool, but am pretty sure that the lexan trim
tab is 3/16 of an inch. I do like that its not very obvious. Step back a few feet
and you cant even see it!

For the new comers, here is an old article I did for Alabama Aviator
web page. I'm surprised it is still up after well over a year:
http://www.alabamaaviator.com/isaa.asp?id=72867
The photos are tiny, but you can still make out what they are.
The Alabama Aviator is a good site, especially for those of us that

Be careful to only add the absolute minimum of weight to the trailing
edge of the rudder. If you add too much weight, it will flutter. Guess
how I know this?

Hi John, always read all your post & enjoy them tremendously. I'm not at
all surprised your article is on the Alabama aviator website yet! It is a
wonderful story for aviation and ultra-light aircraft in particular1 As a wannabe
pilot, its hard for me to imagine doing a trip like that once. Please keep up
the good work with your articles. What i especially like in your post, is
that i've never heard you talk down to any low time pilots or wannabees like
myself, and to me that only adds more interest. Best regards, Dave Culver

I just can't let this pass.....why? Is this somehow connected to Erwin
Schrodinger's paradoxical cat or Heisenberg's uncertainty principle?
If you cannot observe the bubbles they're not there? Surely the
transparent fuel line isn't that porous? Experimental data to back this
up?
Yes, I know the above relates to quantum states, not the
macroscopic world, but you get the drift.....

Hi Jim:
What I was saying was the bubbles are going to be there no matter what
you do. The bubbles pose no problem to me, in that they do not affect
my engines performance. Bing took care of the problem by providing a
system to seperate the air from the fuel before it enters the main jet
well.
Nope.........I didn't say or intend that the bubbles were not there if
I could not see them. ;-)
Did not say the plastic line was porous.
Have no experimental data to back up what I said.
I do have the experience with my engines and fuel systems though, to
more than adequately back it up.
Nope, don't get the drift. Not looking for it.
Take care,

Hi Ed:
I don't know.
I bought one of those David Clark helmets their headset fit into, but
never could get comfortable with it and sent it back. That was years

The use of non-transparent fuel line may have its roots in the radio
show, Click & Clack, wherein they sometimes advise placing black tape
over a gage to "eliminate" the suspected out-of-tolerance reading.
And while you are replacing the see-through line, buy one of those
Magic Mile Maker thing-ys that clamps around the fuel line,
decreasing fuel usage.

Ron,
The bubbles are possibly of some concern, the fuel pressure loss is
definitely something to be concerned about. My fuel level is 30 + inches
below the fuel pump at times and my fuel pressure stays very constant. I
also use EIS to monitor fuel pressure and have never had it to alarm with
the engine running. Is your tank properly vented? Do you have a fuel
filter on the suction side of the pump and if so is it located down at the
tank or close to the pump? How often does it alarm? Any kinks or callapsed
hose on the suction side?

Looks good. Couple questions: How does the radiator work up ahead of the
engine? I had my radiator in that location for a while, finally decided
it was acting too much like a spoiler - Biggest problem was if I got up
to operating temps and couldn't go ahead and take off, it overheated.
Because it was too far from the prop, no airflow. But your radiator
looks bigger than the one I had - comments?
How much does the electric flap actuator weigh?

--> Kolb-List message posted by: "Noel" <noel@teledata.qc.ca>
Hello group !
I had a very nice flight today in this wonderfull winter day.
The temperature was around 20 F (-7 C) and the conditions were ideal !
I am posting a few videos made with my camera phone to give you a taste of winter
flying around Montreal ...
The first one shows the majestic St-Lawrence river just north of Mtl, where 3
other rivers join the big one ... That is the Outawais, Riviere des prairies
and l'Assomption ...
Remember that the quality is limited ... and to turn the volume down before playing
;-) You need a recent version of Real Player to play the video.
More videos to come ...

Hello again ...
This is a shorter one ... flying low over the frozen river ...
It look like water at first but watch more closely ...
You will even see some ice-fishing shacks ;-)
The nice thing in winter is that it;'s perfectly safe to fly this way ...
I would not do that in summer ;-)

Eugene,
1) How long does it take to deploy your flaps?
2) Where did you get the electric screw & what's the weight?
3) Where did you get the plastic angle stock?
4) Did you do a before & after comparison of your wing tip mod?
Thanks,

It is not "washout" but is "incidence". I installed one on my FS II but have
no photo; if I did it wouldn't show much more than the original bracket.
Will allow you up to approx. 1/4" adjustment up or down on the rear of your wing.

" Is your tank properly vented? "
Yes. I measured 2 inches of water pressure on a
manometer taped into the fuel tank vents during level flight.
"Do you have a fuel filter on the suction side of the pump and if so

Yes I normally have a fuel filter in the sentiment
bowl. However, I removed it for the testing. So it would not impact
the observations.
"How often does it alarm?"
The alarms seem to increase as the fuel level in the tank
goes down. The alarms first occur at about 10.9 gal out of 13.4 gal
at the start of the flight. The alarm flashed so fast I couldn't see
what the parameter was. Later (about 30 min.) the alarm stayed on
long enough to identify it as the fuel pressure. Later still (about
35 min) it stayed on long enough for me to watch the fuel pressure
fluctuate between 0 and 2 and back to 0 pounds of pressure. I headed
back to the airport then. The alarm was flashing randomly and
frequently a couple of times a minuite. There was about 8.5 gal of
fuel in the tanks. The tanks are in the wing roots. All my testing
was done on the ground with the remaining fuel in the tanks.
The alarming was frequent enough that I turned on an auxiliary
electric fuel pump when I entered the pattern. The alarms
stopped. The fuel pressure no longer fluctuated around 4 to 5 psi
but stabilized at 5 psi. The electric pump is about 4 inched from
the sentiment bowl at the same level.
" Any kinks or collapsed hose on the suction side?"
I inspected for this, however, the fire protection covering
over the neoprene hoses makes this hard to determine. In view of the
last question and the electric fuel pump action, this could be a
problem area. Tomorrow I will determine the adequacy of the hoses to
the engine!
Thanks
Ron

Thanks Richard,
The radiator works just fine never had a problem even on the hottest
days last summer. It may warm up a bit over operating temp in a
prolonged idle. I do not worry about it until temps get over 180.
Temps are 140 +/- while flying. I'll block off part of the radiator
in colder weather. I wanted to keep radiator and exhaust weight in
front of the engine so I could mount the engine as far aft as
possible for maximum prop clearance from torque tubes. I used an
aluminum auto radiator from a Ford Fiesta. It fits nicely between the
wings and slants front to keep the height to a minimum and provide
room for a standard rotax exhaust system.
The electric servo is very light, I would guess less than 1lb. I will
post an exact weight for you this coming week.

Hey Rich,
I knew someone would ask me that. :-)
I lucked out when a local machine shop went out business that used
these servos for a project they worked on. I salvaged several from a
bunch of stuff they were discarding. They were slightly used but like
new.
I believe you can get them from an industrial supply place like
Grainger but they may be a little salty. I could check for you. I'll
also post an exact weight but they are very light.
I did not time the full stroke but they are very similar to speed of
152/172 Cessna flaps, perhaps a bit faster.
The plastic angle is a corner wall protector strip you can get in the
Paint and Wall Paper section of a Home Depot or most any homebuilder
supply place. They come in 8 lengths with stick on adhesive for only
a coupla bucks. Of course the adhesive is on the wrong side for our
use. I simply removed the tape, cut them to little inch and a
quarter pieces, put them all in a jar with gasoline for an hour or
two to dissolve the sticky adhesive then wiped them clean with a
towel and cut the angle with a scissors. Make half of them left and
half of them right. Stick em on with a dab of clear RTV silicone.
Cost ya less then 10 bucks.
As far as the wing tip mods, I have had several Kolb models with the
standard wing tip. It is rather tedious to get the compound bend on
the bow tube just right to do the tip modification. The difference
in handling is that the mod now gives some definite roll control with
rudder only which the standard Kolb tip configuration does not
provide. All standard Kolb models are roll unstable with rudder
control only. I like the looks of it and the roll control but would
I encourage others to try the mod? Probably not.
The flaps and the VGs are what make me a happy camper with my
Firestar mods.

| Subject: | Re: English U-Joint |
--> Kolb-List message posted by: "Carlos" <grageda@innw.net>
Hi Robert,
I have installed the English u joint to correct a minor incidence change in
my Firestar II. I bought my Firestar used and eventually recovered the
fuselage cage due to some fabric damage at the bottom of the fuselage.
When I did the recover I decided to powder coat the tubular cage. After the
work was completed, I found out that the heat of the powder coating process
must have relaxed the fuselage cage stresses built into the cage during its
construction. During the first test flight I found I had a wing heavy
condition of the right side that I didnt have before.
The English U joints allowed me to reset the incidence of the light side to
match the wings together again.
I blocked up the Firestar into a level flight attitude. By moving the
supplied washers from top to bottom,one at a time, I was able to match the
two wings again using a long level across the bottom of each wing until the
bubble matched side to side.
I bought a pair of the U Joints just in case I needed alot of adjustment but
I ended up only using one on the left wing.
I hope this helps answer your questions about the English U Joints. The
joints allow me to zero out my wing trim and avoid speed eating drag due to
aileron trim deflection.
Best Regards
Carlos Grageda

Carlos --
Thanks for the description. I have a couple of questions, though:
What flight characteristic occured due to the "wing heavy condition of the
right side"? Would it have a tendency to bank right?
Did the position of the left wing end up higher or lower than with the
standard u-joint?
And, last, do you have a photo of the joint in place?
Thanks!

| Subject: | Old Kolb Wing Rib Reinforcement |
--> Kolb-List message posted by: "Dan Cooper" <kcooper@ptd.net>
Fellow Kolbers,
Started wing assembly today on my Old Kolb Slingshot after a really, really,
really long delay (do planes still have wings?) and could use some advice.
I=92ve got a blueprint page showing the additional =BE=94 angle reinforcement on
the outer rib, with no mention in the instructions. Unfortunately, there
isn=92t enough =BE=94 angle to do the job. Got no problem ordering more. There
is,
however, 48 feet of =BD=94 angle that isn=92t mentioned anywhere in the prints
or
instructions. I assume it=92s for additional reinforcement of the remaining
ribs (or maybe a trailer to haul it) and have been trying to figure out how
much and where. I would have enough to run along the bottoms but wonder if a
diagonal would add more strength. Anybody have any ideas/plans that show?
Thanks, =91Coop=92 in PA
