--> Kolb-List message posted by: "Carlos" <grageda@innw.net>
Hi Bob,
My Firestar would bank to the right side and I had to hold left aileron
inputs constantly to keep the wings level in flight. I had to raise the
trailing edge of the left wing to correct the problem. By raising the left
wing trailing edge, I effectively lowered the left wing leading edge to
match the right side. It ended up that the left wing trailing edge which is
very near the U-Joint being slightly higher than the right side wing
trailing edge as viewed from behind the plane.
Because I raised the left wing slightly, I also had to readjust the the
push-pull tubes between the aileron lever and the bellcrank under the tail
boom. This was to keep the joystick in the neutral position along with
ailerons in the level positon. With everything properly centered and
neutralized, I have tried reduced the drag to as little as possible.
Now, I can hold the stick in the neutral position and the wings will stay
level without any inputs from me.
If you have a minor wing trim problem, the English U-Joints are an
effective and practical solution. If you are not sure about how to install
them, you should contact Kolb for further help.
I will try and get a photo as soon as I can pry my digital camera away from
my daughter (She thinks it belongs to her!)
Best Regards,
Carlos Grageda

Are there any Kolbs registered as AULA in Canada? Will TNK issue

Ron,
It might help to insert a short section of clear fuel line just before your
engine pump. If you do not see bubbles here but continue to see them after
the pump, you may have a diaphragm starting to go bad, a pin hole leak on
the suction side of the casting or loose screws holding the pump together.
If you see bubbles before the engine pump, it indicates that there is a
failure some where before the engine pump. You may have a small crack in
the fuel line, or a connector that is not tight, etc. If you turn on your
electric pump and the bubbles disappear, it is a further indication of a
small suction leak between the electric fuel pump and the engine pump.
Also there was a service bulletin out on your engine model describing cracks
found in engine pump inlet region. You may want to check out:
http://www.auf.asn.au/airworthiness/912031.pdf
Hope this helps you out.

Ron/Jack/Gang:
After rereading the SB, looks like activation of the electric fuel
pump, with engine not running, would be a good way to check for
leaks..
I remember in the old days of ultralighting with transparent fuel
line, spending a lot of time chasing air bubbles to no avail.
Eric Tucker, Rotax, recommended using a fuel pressure gauge to monitor
fuel pressure.
Was thinking, that's dangerous for me, it might be a good idea to
check the fuel pressure sender for the EIS. If the warning is raising
Hell and the engine is continuing to run normally, could be indication
there is a problem with your fuel pressure monitor.
Just trying to help.

John,
Thanks for posting the article - great trips make for great reading.
Did you have any problem with carrying a survival rifle at Canadian customs?

AZ/Gang:
No problem taking survival rifle or shot gun into Canada if barrel is
at least 18.5".
No handguns allowed.
Must buy a weapons permit for $50.00 CDN (30.00 US). Is good for one
year. Customs will be happy to sell you one. ;-)
A letter from Air Transport Canada can be downloaded from their web
site. This autorizes you to fly your US Experimental Aircraft into
Canada.
Most of the time you will not meet a Canadian Custom Inspector, but
get cleared over the telephone. I usually call Candian Customs prior
to departure from the US and let them know what my ETA is, in addition
to the normal flight plan with the comment ADCUS (advise Customs).

Gang,
Fixed my problem. I replaced the rivets holding the Wing Fold Tube in place
with 3/16" AN- bolts, washers and lock nuts. (Yes, if you have a wife with
small hands it is possible for her to get the washer and nut on the inside of
the boom tube.) This really anchored the wing fold tube in place, but the problem
still exsisted in that the bolts were supporting the weight of the wings.
So, after getting an ok from Travis at Kolb, I mixed up some JB Weld and filled
in the voids on both sides. On the right side, the void was really big, like
about 3/8" bigger than the tube in some places, so the tube was just "floating"
in the middle of the hole. I didn't notice, but as the JB Weld dried, it
trickled down the inside of the tube so that only a small thread connected
the wing fold tube to the boom tube. Still, even this small amount really solidified
the Wing Fold Tube. So, I had my wife (with the small hands) tape the
inside of the boom tube and reapplied JB Weld and it worked fine. The tube now
is very solid. Just to be sure, since there are no rivets on the right side,
I made up a small plate and riveted it under the Wing Fold Tube. The wings
fold up very nicely now and line up with the Wing Fold Tube better than they
ever did.
Thanks for the help.
AzDave
(For those of you not aware of the problem, the original builder apparently
misaligned the Wing Fold Tube and elongated the hole in the Boom Tube to make
it fit. This caused the weight of the wings to be carried by the rivets instead
of the Wing Fold Tube, and rivets kept breaking.)

Richard / Richard and fellow Kolbers,
Back at ya with the info on the electric Linear Actuator I'm using
for my flaps.
Electrak 1, model S12-17A8-06
12 VDC, 75 lbs. load rating,
stroke length 6 ",
and it weighs exactly 1.45 lbs.
You can find it here -
http://www.linearactuators.com/PDFs/Catalogs_and_Brochures/
Actuator_Catalog_Industrial_Section.pdf
But also check out ebay item #
4611331619, also 4612266425, and 8035475116
may be of interest to ya.
One caution, not all models have built-in limit switches.
