I went for a bimble last night! The end of a hot day, cloudy, but visibility
was okay. Being a low-hour pilot on the Kitfox II, I choose my flying
conditions carefully, especially after a few high-speed exits from the
runway and a couple of pirouettes. Last night, the wind was about 7 knots
straight down the runway, so I pushed her out the hangar, pre-flighted and
fuelled her, and after a second check of conditions, away I went.
I took in the local sights like many times before, passing over stately
homes, before heading down to the Cotswolds hills. The air was sooth as
silk, and with the Fox trimmed down, I was cruising at 70mph at 5600 and
just taking in the beauty of it all as I orbited a hot air balloon at a safe
distance. As the sun would soon be setting, it was time to head back to the
fold, and as it was so humid, I decided a slow powered descent from 1,500
feet to reduce any risk of carb icing.
As I approached the airfield at circuit height, I announced my joining
downwind, and not another aircraft heard or seen. Absolutely perfect. The
windsock showing about 20 degrees left of runway 22 as I let down 10 degrees
of flap.
As I turned base, I noticed another hot air balloon had landed in the field
below. It was one of those big ones carrying 12 passengers! Time to turn
final. A little too high, as I had been distracted by the balloon, so I
eased back on power to idle and lined up. Everything looking good. As I
approached the numbers I started the flare and held it off, and off and off,
until the tailwheel touched a fraction of a second before the mains!
Perfect, what an end to a great hour of flying, until I heard "Tango Zulu,
final for 22"
Where the heck had he come from? I knew he was a Hatz, and they don't
approach slowly, so had to make a fast exit from the active!!
Lessons learned!
1) Continue to announce your position in the circuit
2) Keep a good lookout, even if you hear nothing in circuit!!
3) Don't let yourself become distracted.Looking at the hot air balloon,
instead of long final, may have helped!
4) Even on a quiet evening, don't hang around on the active. If 'Tango Zulu'
hadn't of announced his final, he may had to have go around, or even worse,
being a taildragger also, he may not have seen me!
Well, on to the next lesson!

Awhile back someone suggested cutting the windshield into two pieces and fabricating
something out of metal to join the two halves together near the curve
on top of the windshield. As I recall the thought on this was to take some of
the stress off the sharp bend which might prevent cracking and crazing.
Just wondering if someone tried this and whether it worked.

Very interesting narrative, Peter! I learned a new word too. Bimble. That
must mean something good and fun, right?

Jimmie,
I was "one" that suggested such a thing but haven't done it yet. I
replaced my windshield with thinner Lexan and it still crazed. The next
time I replace it I'm going to attempt such a mod. My thought is to cast
the portion of the windshield in the compound area while it's still
installed and use the cast to fabricate a fiberglass transition piece.
That's about as far as I've gone with the idea. To me, it would be easier
to make a fiberglass piece than try and beat metal into the proper form.
But, I'm not sure. I may not need to make a cast either. I could just lay
up glass on the existing windshield and once cured, trim to fit??????

--> Kitfox-List message posted by: John King <kingjohne@adelphia.net>
Lynn,
The three holes are there because no two Kitfox's are not only not built
alike, but are not loaded the same. Like you when I built my Model
IV-1200, I also did what they did on the factory aircraft, used the top
hole. During flight testing landings I could not three point the
aircraft with the stick all the way back. After moving the horizontal
stabilizer tab down to the middle hole, three point landings were easily
achieved. Problem was that I had to rebuild new fairing for the
stabilizer/fuselage interface. Back to the paint shop.
I didn't have that problem with the Series 6, since the stabilizer trim
does that automatically.

Jimmie...I heated my windscreen with a heat gun in order to take some of
the stress off of that area. I guess it worked because I have
experienced no crazing in this area...maybe I just got lucky.

Steve,
I think you might have gotten lucky. I called the Lexan people years
ago when I was getting ready for my first installation. They said, "
Applying local heat wouldn't do anything to help the situation of crazing",
"The material had to first be dried around 200 degrees to remove all
moisture", "Then, increase the temp to around 300 degrees" (I forget exact
temp), "Then, bend and allow to cool slowly".
I installed heat lamps on both sides of my windshield for several hours
in an attempt to dry and slowly heat. Then applied heat with a heat gun as
I pulled the Lexan into position. Did everything I could think of and it
still crazed shortly after installation.
I don't understand how some have installed the Lexan and it never
crazed????

It very well could be environmental Don. At the time of installation I
lived in the Mojave Desert...a place with zero humidity...in fact, it's
so dry that a tin can discarded a hundred years ago will still be in
very good condition. The sheet of GE Lexan had been in the desert for
several months prior to installation...that could have been the
difference I suppose.

Steve,
Wow, I guess you don't have to dry what ain't wet.. This may be the key to
what Lexan was saying (It must be dry before heat bending).

Great Steve. Two years is the best I heard of. Wish we could figure out
what you did right to prevent the crazing. Seems to me the process of
heating would dry the material, so I think there is something else at work
here. We must have a Mechanical Engineer and a Chemist on the list? Help
us solve this widespread problem.

FYI I put mine on over three years ago, according to the instructions by cutting
out a little more material than necessary around the king pin fixtures and sanding
the cut out edges some. It had been stored in my cool, damp basement for
several years and was cool (65*) when I installed.........no cracking or crazing
either, but then, not flying yet or out in the extremes of heat and cold.

The person who built my Kitfox heat formed the windshield in place. First
he fabricated a jig by pulling a laminate off the aft edge of the top cowl.
He than mounted this jig in place after removing the cowl. He cut out the
one piece windshield / skylight and mounted it with clecos across the top.
He then bagged the whole thing with "space blankets" with a duct connected
to a heat gun. He also installed some thermocouples to measure temperatures
at various places. Using the heat gun he heated the bag enough to allow the
front of the windscreen to sag into place. Working outside the blanket he
pulled the sides together to the door frames, particularly at the top
compound curve. He then went into the bag and clamped the windshield around
the cowl jig and door frames. After clamping he heated again, held at some
temperature, and then let the whole mess cool. The result was a window that
was "almost" completely formed. (It still must be sprung into place, just
not as much. ) The reason he went to all this trouble was that it was
0.110" thick lexan .

Hi,
I don't know if you already received an answer. I've never heard
of an epoxy that wasn't fuel proof, but if you can say which Hysol you're
referring to, I could probably find a definitive answer.

| Subject: | Old Kitfox IV kit Restarted |
--> Kitfox-List message posted by: "Colin Durey" <colin@ptclhk.com>
Hi folks,
am a newbie to the Kitfox family.I just bought a part
finished Kitfox IV kit that was first shipped from the factory
sometime in 1995. After an initial period of activity, the orginal
owner mothballed it for about another 6 years, then, after another
short burst of enthusiam, virtually abandoned it. The kit is in excellent
condition, with about 30% or so completed. Apart from some obvious
issues such as the internal condition of the engine (never been run),
I was hoping you might be able to offer me a few pointers as to what
to be aware of/concerned about, as I try to get it underway again.
There are a couple of cans of paint and glues in the assemblage of
bits, and, although never opened in all that time, I am guessing that
they are probably only fit for the tip???
I am located at Mt Kuring-gai, a northern, outer (very) suburb of
Sydney, so am on the other side of the planet to most of you. If you
know of other Kitfox owners in this region, I would appreciate knowing
their contact details.
Regards
Colin Durey
