Lowell, I do agree although I will say -- I have seen hundred of Kitfoxes taking
off and my videos do speak for them selves with droop tips.
I flew and Lite squared last year for about 5 hours on floats ( model 4 1200 basically
and it was pathetic compared to my I 1050 , both had 582 but it had
no wing tips. Just squared off ends. I suggested to him to contact Mc Bean and
get some hoerner style tips and he would get off the water faster I think.

For calibrating the iron used in covering a plane with Polyfiber,
they have you squirt a blob of silicone-based heat sink compound on
the bottom of your iron, then lay their thermometer into the compound
and cover with a 1/2" thick stack of paper towels. Then turn the iron
on and calibrate/ record what the thermometer says for various
locations of the irons' dial.
They also point out to be SURE to get all the silicone off the iron
before using it to shrink the fabric. It's all there in the
instruction book....yeah, I'm sure. : )

What John sells with his kit (I bought one too) is Tygon, or at least it was
when I bought mine from him, and it does OK with 100LL, but not auto gas.
I'm not really sure there is a product that will work and I may just have to
accept changing the hoses every couple years. Not a huge deal.

Thanks, Guy. I think the key here is the auto fuel has additives that
discolor the urethane where the 100LL, without the same additives, seems
to be gentler on it. At the cost of 100LL these days, I'll just change
out the tubing every couple of years.

Deke,
I use the blue tubing with a white background and a red tube
from a Chem-tool spray can inside. I can see the fuel level pretty well
in daylight, though not as well, I'm sure, as new clear tubing. Next
time I'll use stainless rod inside. My tube has not discolored, but I
use 100LL exclusively. It has oxidized on the outside over the last four
years which makes it a little harder to see through. I'll probably
replace it when I re-engine this year.

| Subject: | re: wheel tracking |
Whether you want toe in or toe out depends on whether you have conventional
gear or tricycle gear.
On conventional gear toe in will make the plane very squirrely while
landing. If the tail goes one side or other on landing the main gear will
swerve the opposite direction this can lead to a ground loop.
On tricycle gear toe in is not really necessary as the CG of the plane tends
to keep things straight. However some planes do have a little toe in to
help assist in keeping the plane straight.
Either way toe in or toe out the shift from straight is usually about 1
degree max.
If you are worried about your bungee gear not being able to handle a little
toe out then you better stay away from grass strips where it will get far
more workout. These are very light planes and if your tires are wearing on
the outside it sounds to me like you have way too much toe in.
My plane a model III-A ( That is what it was sold as by Denney) The toe in
can only be changes by de-tempering the welds of the legs, using brute
force, then re-tempering the joints. If your axel stub is bolted to the
leg/s then I assume you do have a spring leg.

Malcolm
Before you consider attempting to change the tracking of your wheels,
consider this. What I'm talking about is the gear leg that uses bungee
cords and not the grove gear. With bungee cords, the gear is toe in to keep
the bungee cords from extending and wheels spreading outward during taxi and
take-off. Naturally, if the wheels were toe out, then the gears would want
to spread out and the bungee cords would stretch. The perfect scenario
would be to have a straight track, but even with that, I think you may be
looking for a potential problem. You need to decide if replacement of the
tires and expense outweighs the possibility of bungee cord breaking and more
expensive damage and repairs.

FWIW, the oil injection system parts are very expensive. About $800 if you buy
all new stuff. The pump is $285 new. I found a pump taken off a new engine
for half price from a guy that didn't trust oil injection. The tank with low
oil warning capability, cap, lines, and filter are off a 99 Ski Doo Skandic from
ebay for $20. New from rotax is about $200. The manifolds are "recycled"
from CPS for half price.
After I started collecting parts it became evident there are quite a few Rotax
oil injection parts sitting on shelves owned by people that don't trust the system
or for some reason think it is too heavy and robs power.

Malcom, from your measurements my rough calculation is that each wheel is toed

if you are happy with how it handles.

Lynn,
You are spot on. I just checked my manual. That said, I still think I
would avoid any possibity of silicone contaminant on a paintable surface.
The electronics tech guy at Kitplanes suggested a possible replacement for
the silicone stuff - the white goo painted on sunburn sensitive noses. The
Zinc Oxide is the heat transfer agent in both. What I did is drill a hole
in a piece of aluminum and glued the thermometer bulb in it with some epoxy
moxed with some aluminum grindings in it. Put this on a towel face up and
rest the iron on that and the broad contact between aluminum pad and iron
bottom gives very good heat transfer.

This revives a queation I have been mulling as I read this these posts. My
airplane had the heat bendable tubing once offered as standard with the
kits. Was it discontinued because of the giant plastic fittings necessary
for it's installation. I recall that these would loosen over time and leak
a bit - on a pretty regular basis. With the talk of the need to change out
the barb secured tubing, maybe tightening these giant fittings periodically
is not such a problem after all.

Lowell, my sight gauges were previously what you are referring to. They
also discolored over time which is the reason I changed them out and
converted to the barb setup. However, I never had any leakage problems.
The barb and Tygon method is much simpler and a snap to change to new
tubing. It's that auto gas that is responsible for the discoloration, in my
opinion, which is all I burn.

| Subject: | Re: Rotax spark plugs |
Years ago when I ran a production photo lab we used heat transfer data
printing on the back of our prints and the temperature of the print head had
to be exact. Too hot and the coating on the paper would blister or burn,
too cool and the print medium wouldn't transfer to the paper. The system I
used was a series of wax pencils that would melt at specific temperatures.
Simply mark the iron with say the 285F pencil the 300F pencil and the 315F
pencil and when the first two marks melted and the third one didn't you were
right at 300F.. Using that technique you can quickly locate any hot spots
on your iron as well as quickly calibrate the iron. The two advantages are
you can quickly test the iron and clean up is just a wipe with a paper
towel.
If you want I'll dig out the pencils and get a brand name for you.

Lynn,
You are spot on. I just checked my manual. That said, I still think I
would avoid any possibity of silicone contaminant on a paintable surface.
The electronics tech guy at Kitplanes suggested a possible replacement for
the silicone stuff - the white goo painted on sunburn sensitive noses. The
Zinc Oxide is the heat transfer agent in both. What I did is drill a hole
in a piece of aluminum and glued the thermometer bulb in it with some epoxy
moxed with some aluminum grindings in it. Put this on a towel face up and
rest the iron on that and the broad contact between aluminum pad and iron
bottom gives very good heat transfer.

Whether you want toe in or toe out depends on whether you have conventional

On conventional gear toe in will make the plane very squirrely while landin

On tricycle gear toe in is not really necessary as the CG of the plane tend

Either way toe in or toe out the shift from straight is usually about 1 deg

If you are worried about your bungee gear -not being able to handle a lit

My plane a model III-A ( That is what it was sold as by Denney) The toe in

Hi Lowell and all=2C
I received my kit in Aug of 1993. The tips that came with the kit were 2 p
iece and you had to epoxy them together. The form before installing them s
howed that they were under cambered. I called the factory and they told me
that they were from Model 3's and would work just fine on the Model 4. Wh
en you install them you force the camber out. The droop tips do work. A T
uft test showed no turblance and yarn layed flat when wing was stalled. I
have pictured to prove.

You're right... I did the math and while I didn't come up with Lowell's
answer, it was close enough for government work ;-), the difference was
0.01 degree.

Subject: RE: Kitfox-List: re: wheel tracking
Whether you want toe in or toe out depends on whether you have conventional
gear or tricycle gear.
On conventional gear toe in will make the plane very squirrely while
landing. If the tail goes one side or other on landing the main gear will
swerve the opposite direction this can lead to a ground loop.
On tricycle gear toe in is not really necessary as the CG of the plane tends
to keep things straight. However some planes do have a little toe in to
help assist in keeping the plane straight.
Either way toe in or toe out the shift from straight is usually about 1
degree max.
If you are worried about your bungee gear not being able to handle a little
toe out then you better stay away from grass strips where it will get far
more workout. These are very light planes and if your tires are wearing on
the outside it sounds to me like you have way too much toe in.
My plane a model III-A ( That is what it was sold as by Denney) The toe in
can only be changes by de-tempering the welds of the legs, using brute
force, then re-tempering the joints. If your axel stub is bolted to the
leg/s then I assume you do have a spring leg.

Subject: Kitfox-List: re: wheel tracking
Malcolm
Before you consider attempting to change the tracking of your wheels,
consider this. What I'm talking about is the gear leg that uses bungee
cords and not the grove gear. With bungee cords, the gear is toe in to keep
the bungee cords from extending and wheels spreading outward during taxi and
take-off. Naturally, if the wheels were toe out, then the gears would want
to spread out and the bungee cords would stretch. The perfect scenario
would be to have a straight track, but even with that, I think you may be
looking for a potential problem. You need to decide if replacement of the
tires and expense outweighs the possibility of bungee cord breaking and more
expensive damage and repairs.

Where is that located, Pete? Around here it's going for $3.75-3.85-

used to show it at a given price..sorta low...then you find out that
they add the tax in after the pump quits running, instead of

Lynn, I remember when I built my home in the early 70's a friend said, "Put
a gas tank in the ground. You can save $.05 a gallon buying it in bulk with
the convience of delivered to the house". I lived in the country in a
farming community. I spent a couple of $100 to buy the tank and have it
buried. I bought gas delivered to the house and saved $.05 a gallon for
about 2 years. Then Farm Service decided to increase the price to deliver
less than 300 gallons. A new concept of pay at the pump with credit card
and pump it yourself came along. It cost $.04 a gallon less at the gas
station then. I think Pete lives in CA.

Either that, or the folks at Rusty Allen are hoping for you to buy
oil, coffee, charts, etc., while there. I've seen some places drop
the price hoping to get traffic to come in and increase their number
of airplane "operations" and impress the FAA (or whoever....State
funding, runway improvement surveys, etc.) into sending money their
way. In our state of Michigan, Jackson (JXN Class D) recently had
more operations than Lansing (LAN Class C), sending the message to
somebody that Jackson might need more funding than Lansing is getting.
We recently had a "suit" visit our EAA chapter urging us to "visit
the airport" and help keep up our numbers. : )

Yeah, Pat, I know that the tank at home sometimes is not the cheapest
way to operate, but I like the convenience of not having to fly
somewhere to fill up. I did some math one day and figured the cost of
flying to various distances to get fuel, and (not recalling what the
figures were) it usually didn't make it cost effective to fly out of
your way very far to save a few cents. Now if I'm heading to "X" for
example, and I'm low on fuel, and they're close to what the cost is
in my tank at home, I'll fill at their place. Sometimes I just fill
there anyway, to thank them for the use of the car, etc. (I fill the
car, too, if there's room in the tank)
P.S. A friend gave me my tank, so my cash outlay was pretty low to
get started. I also have a hangar-mate next door, and he gets 100
gallons to my 300, so maybe the delivery charge is waved. My fuel
comes from Air BP out of Toledo, Ohio, about 75 miles away, and they
deliver all around the area, so I get it when they are "in the
neighborhood."

If the initial measurement was taken after the plane was pushed
backwards, the measurement was done incorrectly. The plane must be
pushed forward 8-10 feet to neutralize the landing gear before any
measurement will make any sense. The plane in question might be
different, however.

Noel,
I just drew a 72" line with approximately 2-5/16 offset and had the program
calculate the angle. My guess was that original measurements were eyeballed
and and that is what I did on the computer. It has been over 50 years since
I had trig, so the cosine stuff was way out of my league.

Malcolm,
I calculated total toe in as you gave a measurement that gave total
difference front to back of your rods. I think Noel gave the toe in for
each wheel. His combined would be 2.25, which is close to my calculation.
I have done several such measurements on different landing gear sets and the
right and left are usually not the same. I have found on occasion that the
total discrepancy is on one gear leg alone.
Regarding your question, I think I would go on the feel of the airplane on
landing - if it doesn't feel squirrely to you, I would ignore it. If you
are concerned with tire wear, you might consider tweaking it, but that
procedure can be a challenge. What you might do is remount the tires so you
will wear the opposite side.
Lowell
