| Subject: | Setting up the Fuel lines |
So when I get home I replacing my fuel tanks and re-running all the fuel lines
since I don't like the way the builder did it. The fuel lines come out of the
tanks on the bottom of the rear inboard portion of the tank, I believe this is
where the drain or strainer is supposed to go. the port on the inboard side
had a line with a valve on it that could be used, very infrequently, for draining
fuel. Once inside the lines run behind the seat and under the door up to
the header tank behind the panel. I don't like that the lowest point of the
system is in aluminum tubing under the door. there is also no vent for the header
as it is plugged off instead of going back to one of the tanks. this should
go to the TOP of one tank, correct?
So how do you have your lines running? How does the manual recommend running the
lines? Is there any benefit to going to the nylon header that goes behind
the seat? Any other thoughts? Thanks.

| Subject: | 1.4 lb Battery!?!? |
U Fly It is advertising a new LiPO battery that only weighs 1.4 lb and is supposed
to be a drop in replacement for use with HKS and Rotax engines. My first
thought is that this can offset the slight forward shift in CG associated with
the HKS engine. Also, dropping 10-15 lbs is a pretty nice weight saving plan.
I think it was about $250 so you definitely have to pay for the pounds.
My biggest concern is that my experience with lithium is that you have to be careful
charging it. Would our charging system have to be modified so as not to
charge it to quickly? Anyone in line to buy one of these yet?

James,
I think this will be pretty much the consensus over the years. The later
Kitfoxes use a header tank that is placed near the bottom behind the
passenger seat. Because this becomes the low point in the system many have
done away with the gascollator. The fuel lines are run from the main tanks
to the header tank, then at the side of the seat to the shut off valve.
Some, myself included have added a switchable 4.5 psi max Facet fuel pump in
the aluminum line just out of the header tank.

| Subject: | Re: best way to adjust toe in? |
Jerry,
First a story. I used to use a local (Alaska experience) DFI for my
BFRs. He liked to play with the Model IV during the check ride and I
usually had to replace the tires after each BFR. I couldn't seem to
convince him that the cowl on the Kitfox tapers toward the prop and if
you line it up like you do in a Cessna, using the side of the cowl as a
reference, you are always landing in a crab. I mention this because
your ground down tire is on the right side which is exactly what would
happen if you are using the cowl side to line up the airplane on
approach - you might be touching in a slight crab. One early
recommendation, when I was doing my first airplane's test period, was to
line the airplane up - on the ground - with a distance object (tree)
then get inside, find your comfortable seat position, then with a grease
pencil or a piece of 1/8" masking tape draw a vertical line on the
windshield over the distant object. This way you have a real visual
reference on what is really straight ahead.
regarding the toe-in. Early on the factory sent out a service letter
and this is basically their recommendation. First, secure the airplane
to the floor. I made an "A" frame device bolted to the floor that
secured the tail. (This is needed if you want to follow their
instructions in correcting the alignment). Then drop plumb lines from
the main tail wheel bolt to the floor, and from the mid point of the
belly between the gear legs, then connecting those points you would get
the long axis of the airplane. Then you will want to find the angle of
each wheel (axle) and determine the tow-in. When I did it, I clamped a
piece of angle iron to the axle and again dropped lines to the floor and
by extending these lines, I was able to determine the angle of the
axles to the center line. I think you will find that with the early
landing gear, there is up to 3 degrees toe in as a matter of course. I
f you have a cad program or a friend who has one, these measurements
will be an easy calculation in the program.
Straightening the toe in is basically, putting a piece of pipe over the
axles and muscling them into alignment. I put a piece of copper tubing
inside my cheater pipe to protect the threads. The results was quite
surprising. That .049 wall tubing weldment is surprisingly tough. The
gear legs held firm and the correction was all in the axles. It is mild
steel and bends quite nicely. I did have to shim my brake caliper with
washers to bring it into alignment with my new axle position. If you
really want to tweak the legs themselves, you will need some heat - like
orange.
Another way to do a quick and dirty check on alignment is to position
your airplane and at the aft most position on the tire (axle height),
put a piece of masking tape and a vertical mark. Do this on each tire.
Measure between the marks, then move the airplane forward until the
marks are at axle height on the forward side of the tire and measure
again. This will give you a ball park indication on the alignment. It
won't tell you which gear leg to concentrate on, but will indicate an
overall problem.
Hope this helps.

Is there anyone that can tell me the best way to adjust toe in on
a Model 2 , the out side of the right tire is wearing out fast ? Or is
it the camber?

Lowell, I had a hell of a time lining up on the runnway until I put a piece
of black electrical tape on my cowl to give me a reference to be aligned
straight down the runway on landing. I wouldn't call the crab "slight" when
I used the unmarked cowel to line up. It was a "big" crab that was not
managable. I still have to tell myself I use the tape to line up as it still
looks like I am crabbed to the left when I am properly lined up.

| Subject: | Re: Setting up the Fuel lines |
James, My fuel routing sounds similar to yours. But, I do have a vent line
from the nylon header back to the wing tank. The header tank is to be
mounted low behind the seat to give a reserve when steep desent unports a
wing tank. I had an aluminum header tank mounted much higher and John McBean
suggested the lower mounted nylon tank. I do have shut off valves on each
wing tank supply line and the vent line also.

Jerry,
One thing to consider is that IF there is any camber (tops wider
than bottoms) when the plane's horizontal then you'll have massive
toe-in when it's three-point, regardless of how much toe-in you have
when horizontal. Just FYI.

James,
Let's see: wing tanks, strainer, 1' of 1/2" flex tube turning aft
along upper fuselage member above triangular window, converting to 3/8"
aluminum tube, around the seatbelt mount and back forward to the top of
the poly header tank low behind the bulkhead behind the right seat. 1/4"
Aluminum tube vent from the top of the header tank to the top of the
right wing tank. (Blue 1/4" fuel line from just over the rear corner of
the triangle window to the tank.) Fuel drain out the bottom of the
header tank. (My gascolator.) 3/8" fuel pickup centered two inches above
the bottom of the header tank to a fuel filter just forward of the
header tank, around the right seat below the door sill, back to
centerline to a fuel valve in my "center console", then forward through
the firewall just above the lower motor mount bolt.
The only benefit to the low aft header tank is that it acts as a
gascolator and that it vents uphill all the way to the wing tank. (You
have trouble pushing bubbles down hill.)
