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: RE: Kitfox-List: 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: RE: Kitfox-List: 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 .

not sure size really  about  # 8s maybe ? 

I also made gap seal coversimilarar for the top of the horiz stab.
not sure why it was left open.

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

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.

Subject: Kitfox-List: Boneyard


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
