Thanks Jim. I also have a tiny flashlight as the keyholder of my Kitfox's start
key. I can use it do check the wing tanks in the dark, of course.
But I thought you guys were talking about something you inserted in the sight gauges.
I was wondering what it was and how to get it in such a remote place as
Norway.
Was I wrong to think that it was a kind of floating ball, the size of the gauge?
Cheers,
Michel

John,
Right tank will have 4 holes. Bottom is the outlet, top is the vent and
the other 2 are for the sight gauge. Left tank has 3 holes.. no vent. Hope
that helps.. if not contact me off list I can fax you a diagram.
Fly Safe !!

Subject: Kitfox-List: Fiberglass tank installation
--> Kitfox-List message posted by: "John Bergen" <JBergen@rrc.mb.ca>
I'm installing fiberglass tanks in a series three that used to have
aluminum tanks. Skystar was kind enough to send me most of the parts to
install but no instructions. They have also proven to be impossible to
contact on the issue.
I have two tanks, some plumbing, two tubes of sealant and a handful of
stainless pop rivets.
Each tank has three holes on the inboard sides.
Anyone able to help me decipher how to install them and what the extra
holes on the inboard sides of the tank are for? I'm guessing sight gage.
Thanks in advance.

--> Kitfox-List message posted by: kerrjohna@comcast.net
Harbor Freight has a great little laser/level for $19.95 I think that is ideal
for the kind of precision we are talking about. Use the propeller manufacturer
provided guage to get the approximate static rate desired then use the laser
or digital it insure that all the blades have the same pitch.

John,
No, the cradle that I had would slide up the blade about 6-8". I really
didn't care what the actual angle was, I was only concerned with getting the
blades set so that the engine turned a certain desired static RPM. Then I
wanted to get all blades set exactly the same. I have no idea at what angle
my blades were set, and couldn't care less.
Cliff
You measure the blade angle at the tip Clifford?? John A.

I've never used a laser, I used a digital l
evel, about $100. But I use it
for many other things. You could probably go to any hardware store and
find
a cheap laser. The trick with either of these is to build a cradle that
fits
on the prop blade and holds the laser or digital level. I made mine out of
wood, and it was just a cradle that had 3 contact points and would slide
up
the prop blade. It allowed repeatabilty and stopped at the same spot on
each
blade. The 3 contact points had a small groove that fit the edge of the
prop
blade.
I no longer have that plane or prop and the cradle went with it, so I
can't
even take a picture of it for you. But I'm sure you can figure out
something that will work. Just make sure it allows precision and
repeatabilty.
Cliff
Cliff,
Where can I by one of those lasers? I have never liked the bubble deal on
my Warp Drive. Are they expensive? Thanks, Jeff Puls 912UL

I forgot to add....
Use a digital level or a laser to set the pitch of the blades, if they
are
individually adjustable like the warp drive prop. With the little bubble
&g
t;level that comes with the warp drive, they claim only 1/4 degree
accuracy.
With a digital level you can get 1/10 degree accuracy and with a laser
you
can probably do that or better, if that's even possible.
With these 3 things, carb sync, blade indexing and blade pitch, you can
make
your Rotax 912 feel like flying behind a turbine.
Cliff
Another thing that can help keep your engine running smooth is blade
alignment.
Rotate the blades by hand indexing them against a stationary object.
Make
sure the distance from the stationary object is the same when you move
each
blade past it. Try to get them within 1/8". You can adjust t
his by
putting
very thin shims behind the prop hub.
Cliff
I originally followed some published procedures to manually sync the
carbs
on my 912S by adjusting the throttle cable lengths. After reviewing
a
DVD
on 912 installation tips from HomeBuilderHelp.com...I determined that
syncing using a vacuum gage was pretty straightforward. With the
gages
in place, I was surprised how out of sync my carbs were. After I
sycned
them..the engine was noticeably smoother in the 3000 - 5000
range...and
at
this
yet, I would highly recommend it. Caution..standing behind the prop
adjusting the throttle cable lengths will mess up your hair. Make
sure
you have someone sitting in the cockpit, and the tail is tied down
well.

But I thought you guys were talking about something you inserted in the sight

Was I wrong to think that it was a kind of floating ball, the size of the gauge?

I'd idle my 912S w/slipper clutch + Ivo medium in-flight adjustable
prop at 1400 as normal procedure. It ran smooth and happy there as
far as I could tell. The carbs were balanced with vacuum gauges, not
eye-balled.

Hi Michel
I use a background of diagonal lines that helps show the level due to the difference
in refractive index between an empty and a full line.
The WD40 spout in the tube sounds like a great idea.
