>Way too much static at 3000rpm and above.
Hello Layne from Anchorage - who happens to be at roughtly the same latitude as
mine; only that we have, in Norway, the Gulfstream current to bring us a slightly
milder climate along the coast. :-)
Radio statics, also called RFI (Radio Frenquency Interferences) has keep generations
of radio amateurs sleepless at night. They may come from almost anything,
even the slowly rotating propeller shaft of my sailboat when sailing!
In our planes, finding their source may be started by finding if the static increases
in pitch with the RPM. It is then certain that it comes from the ignition
system and/or the engine. Next is to find if it is carried by air or through
the power supply. If you use a hand-held radio with only an internal battery,
do you still hear the statics? Then it is airborne. Shielding and/or moving
the antenna at another place may be the only solution. If it is not airborne,
then it comes to your radio by the power supply line. In that case, you should
consider using ferrite coils on the line, or condensers between them. You will
have to experiment, my friend.
Cheers,
Michel Verheughe

| Subject: | Kitfox with radio full of static |
What Michel said and....
I would like to know a few other things though. What kind of engine are
you
using, what kind of spark plugs and spark plug caps. Is the
interference
strong enough to open the squelch on your radio or do you only hear it
on
incoming signals. does it make any difference to the static whether the
radio is in the left or right seat? Finally do radios receiving your
signal
hear the hash?
The reason I ask this is because the 2 stroke Rotax engines are a bit
odd
ball. The later ones with the electronic ignitions require the use of
*both* resistor plugs and resistor caps.
The plugs are BR8ES. This causes a bit of a problem as NGK makes two
BR8ES
plugs one has an aluminium screw on top and is gapped around .030" or
wider.
The BR8ES plugs coming from Rotax have solid steel heads on them and are
gapped .018" for the extra few dollars It is better to get those plugs.
First the steel tops won't break down and cause arcing inside the caps
which
will eventually short out the caps.
About the caps there are maroon and black caps from NGK and I think you
can
get metallic caps from other suppliers I think the only difference in
them
is the colour. What is important about the is that they should have
about
5K Ohms resistance across the inside of the cap.(between where the wire
goes
in and where the plug clips on. To make it difficult to remember, the
centre electrode of the spark plug also has a resistance of about 5 K
Ohms.
If those resistances are shorted out you will get static, I mean STATIC!
To get to my pet peeve... Grounding. Michaels ships are hard enough to
keep
good grounds on, salt can do strange things to metal, airplanes can be a
lot
more difficult. You can get an alternator wine which will get higher
and
louder as the RPM goes up for many reasons.
Check the ground braid that jumps across the engine mount. This should
be a
honkin' big mother of a wire, well, maybe not quite so big as the
starter
cable but big enough to be noticeable. The contacts of that wire should
be
nice and shiny clean under the mounting nuts/bolts on both ends. A bit
of
crud in either those connections can cause RFI. While you are checking
that
wire give it a gentle tug. The terminals on these wires are generally
crimped on and sometimes, not too often, you will get a bad crimp. If
the
wire comes out of the terminal clean it off and crimp on a new terminal.
Check the mount for the voltage regulator. Most of those regulators
should
be mounted to a good ground. Paint or a little rust behind the
regulator
can cause the RFI and interference on the DC wires.
Finally check that there is a really good grounding strap from the frame
of
the plane to the instrument panel if your instruments are grounded to
the
panel.
If you are using an external antenna on your radio, I do, then the
external
antenna should have a ground plane of about 20+ inches under the
antenna.
Get someone to do a SWR test on your antenna from the BNC connector you
attach to your radio. That ensures your antenna has the best tune for
the
com band. Also look for any nicks, bends or kinks in the coax there is
a
chance they will cause you RFI.

| Subject: | Instructions for horizontal tail. |
The tail of the plane can be subjected to a lot of vibration. In the C185s
they have similar fairings around the tail. Those fairings are mostly held
in place by two machine screws and nuts per side, and then several PK screws
I think they were #10. It is amazing how well they can hold! All the tail
fairings on the C are curved to give them extra strength when held
(securely) in place.

Or make it simple and go down to the NAPA store and get 2 inline noise filters
and put one on the hot wire feeding the panel and one on the hot wire feeding
the radio . I can almost guarantee it will cure all your radio noise problems
. They only cost a few dollars and take a few minutes to install .

I have the 3/16 rod ends and always inspect them on preflight. I have debated
whether or not to change to the 1/4 inch. What is the factory official opinion
concerning this?
What has been the result when one of these break in flight?

As I recall Lynn, I believe that is correct. I'm sure the service bulletin
is available on John's web site. Personally, everyone with a IV should have
a look at those rod ends to see if they have the 3/16" units. I'm not
saying they should all be changed, but it's something to be aware of and if
you're in the building process, now is the time to consider upgrading.
Some say it is from mishandling that caused the breakage, which to some
extend may be true. However, there is a lot of down pressure on those rod
ends, even in normal flight. However, in turbulence, they can really take a
beating.

Kay and I finally got to the salvage yard to pick up personal belongings and
look over the remains of N96KL. I thought some of you might be interested
in what we saw.
First, though, was what we felt. I had been concerned with what my emotions
might be when I saw the remains and was surprised to find that the reunion
was a bit dispassionate. It was not very emotional at all. Kay shed a tear
as we drove away, maybe because the airplane had been, in a sense, a bit of
competition with her for my time for nearly fifteen years. I took no
souvenirs, but have numerous pictures taken over those same years and tons
of video footage taken during the numerous flights. Maybe that is why I was
not too moved seeing the pile of "junk" We would have liked to have
lingered longer to just poke around, but the owner of the salvage yard
seemed to have no interest in us or our interests. I guess by agreement, he
stood as guardion of the salvage remains as an agent of the new owners - the
insurance company to see that nothing belonging to them ended up in the
trunk of our car. On the drive out, as we talked about him, I opined that
he probably had zero personality. Kay suggested that it might be possible
to be below zero in that area and we both laughed.
And junk it was.
A brief description. The engine and all attached to it including the
firewall and instrument panel were angled toward the ground so the spinner
flange was at ground level. The windsheld and all the skylight area tubing
was just gone as were the doors. The wings were folded back against a
crumpled fuselage (for trailering) and the empennage was moderately damaged.
The wings were pretty much intact, but the wing spars were damaged as were
the flaperons, but not severly, yet not salvagable without major work. The
empennage looked the best of all the structural components - salvageable but
not without some welding. Interestingly enough, the seats were just sitting
there as secure as could be with the seat belts piled on them with virtually
nothing overhead and everything forward moved forward which provided for
easy egress for us after the dust cleared.
The most striking thing I noticed was that the lift struts were perfect,
including the recently discussed rod end fittings. These are probably the
only structural members that could be bolted directly to another airplane
with nothing needed except cleaning up the fairings.
For those of you that opted for the Hammerhead landing gear when the quiet
war was raging between Grove and Hammerhead, the following might be of
interest. the gear was sheared off completely, but the gear showed no signs
of being bent or damaged in any way. It was my understanding that
Hammerhead opted for 7075 aluminum bent then treated to T6 , which if true,
is really tuff stuff and might explain the fine appearance of the gear legs.
Both tires (Mippi style) were still on the gear and the right tire deflated.
The left tire was still pressurized. I didn't have time to examine the tire
to see why it deflated, nor much time to examine much of any of the engine
or engine compartment. I did notice that the battery was in position snugly
held by the tray and the three adel clamps. The ELT was on the seats as it
had triggered and the emergency folks removed it to shut off the signal.
As to the point of impact? The gear sheared off, the engine was angeled
down which opened up the cockpit area (absolutely nothing above the seats)
like breaking a stick over your knee, both wingtips were damaged, but not
excessively, and the fuselage was crumpled. At the site, the bottom ring
cowl was under the tailwheel. My guess is that we came down hard on the
landing gear and it didn't absorb as much energy as might be expected and
the fuselage folded down over it. We had wondered what had caused the
puncture wound in Kay's calf - there was lots of broken structural tubing
that might have caused that.
The engine was apparently still running as one prop blade was sheared off at
the hub and the engine apparently ran for a third of a revolution as the
sheared blade was in a horizontal position.
One more interesting thing that I noticed. I made a thin aluminum enclosure
to hold the power supply for the video camera. It was about .5"x1.5"x2" in
dimension, mounted by adel clamps and the circuit board for the supply (the
only mass) mounted in the opposite side from the adel clamps. The impact
distorted this box to a parallelogram shape, by maybe 1/8". I don't know
how many Gs that represents, but we feel pretty fortunate we are doing as
well as we are, let alone us both being here.
Regards,
Lowell
