The requirements vary by the inspector. Each has his own quirks and
druthers. Mine didn't even ask to se if the engine would run.
-which if it didn't would be a REALLY safe airplane.
He did ask me to put stops on the aileron controls so they wouldn't
interfere at full throw.
I used an FAA inspector who, at the time, didn't charge anything :)

Im with you Possum, I am putting my VG's in the valleys, I think valley placement
would definatly be better than the tops of the ribs. If you can picture the
airflow in your mind, you want the little "tornados" that the VG's generate
to stay attached to the wing over as great an area is possible. If The VG's
are on top of a rib and the tornados start already on top of a rib, I picture
them being sucked off the top of the rib sooner and not covering or attaching
themselves to as much of the wing area. With the VG's between the ribs, the
little tornados are more likely to flow up from the vally, covering both the valley
and getting to the tops of the ribs before they seperate. THis is a "theory"
of mine, but I base it on on pictures of tests I have seen in wind tunnels
where VG's were tested with air mixed with smoke where you could actually the
tornados and how they attached themselves to the wing and where they finally
seperated...

In my post I said that I was going to CENTER A PAIR of VG's A PAIR .... A
PAIR on the wing ribs, meaning one VG on either side of the wing rib (That's
what CENTER means), A PAIR not a single VG thus leaving two in the valley
(one each from two pair). Look at R. Pike's photos, look at the pictures on
Landshorter's web site. The PAIRS are centered on the ribs. A PAIR of VG's
is two at a 30 degree angle with the front being the closest point of
separation for the PAIR.

Fellow Kolbers,
Several people ask for pictures of my Firestar flap setup.
I just posted several to the kolb photoshare along with several of my
vortex generators and of my wing tip mod.
Please check them out when Mat gets them entered.

Can someone who has the Landshorter's VG's tell me the length of the base of
the VG's and the height of the VG's.
I have a set of home-made VG's and want to compare them. I have a the set
on my Firefly that are of the design by Jack Hart and placed as by his
directions. I am satisfied with the improved performance of the Firefly.
They are made out of valley aluminum and are installed with double sided
tape. Have been on for two years and have not lost any. They are placed in
the valley between the ribs.
Any one wanting a picture of them on the wing, e-mail me off list.
Landings are much easier.

Chris, just to pee on your chips, The land shorter VG photo's may make it
difficult to actually see exactly the pairing position.
In FACT Joa from Harrison designs gave me a detailed hand drafted diagram
of the Recommended and Tested position of the pairs on this type of wing
construction which has (VALLEYS) and the PAIRS were to be mounted in the
valleys.
Well thats my last on this topic anyway.
Kind Regards
Mike

| Subject: | Fuel Line Bubbles |
--> Kolb-List message posted by: Ron Hoyt <rrhoyt@ieee.org>
I have noticed a disconcerting phenomena in the fuel supply lines of
my 912UL. i.e. Bubbles of sizeable dimensions. These bubbles are
showing up at the carburetors after the 912 fuel pump. The fuel pump
provides 15 gal per hour so there appears to be sufficient fuel for
the engine. The trouble is that they trip the ESI fuel pressure
alarm by allowing the fuel pressure to go to zero. I presume this
occurs as the bubble passes into the carburetor.
Is there any experience in the group with this phenomena.
The fuel supply to the pump is about 18 inches below the pump. The
fuel supply is from a sediment bowl that is completely full during
this phenomena. There are no leaks in the fuel system.
Do the bubbles come from the pumping energy of the pump agitating the fuel?
Are they from the vacuum in the 18 inch lift of the fuel?
Will they cause the pump to fail pumping fuel and only pump vapor?
Is the fuel pump showing initial signs of failure?

Hi Ron H:
Best way to fix bubbles in the fuel line is change from transparent
fuel line to top quality Gates neoprene fuel line. Not only will you
not have to worry about bubbles in the fuel line, but you will have a
fuel line that is much more durable and reliable than transparent
plastic "UL" lines.
The Bing carbs are designed to seperate air from fuel prior to entry
into the main jet well, on both 4 and 2 strokes.
I don't use a fuel pressure sender and display on my 912ULS
application, so have no idea if my pressure is going to zero or not.
However, the engine driven fuel pump on the 912 series engines is more
than adequate to lift fuel several feet to the carbs with no problem.
Take care,
john h

--> Kolb-List message posted by: DAquaNut@aol.com
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.

Ed,
My rudder trim tab is on the right side to push the rudder to the left. The rivets
are on the right and the bend is to the right. It works good for me. Mine
is made from Lexan and is less noticable than aluminum.

Ed, you will surely get more replies tomorrow, but I will offer my opinion
now.
I have not seen Kolb's dwg. on the rudder trim tab, but I have seen a bunch
of tabs.
If the rudder needs to be moved to the left, then the tab should be mounted
on the right side & bent to the right.
Don't see where you have a problem.
