No disrespect Charles, but a few questions...
1. How can anyone tell you if there is a problem with your radio from that
picture?
2. Since your plane is parked at Hagerstown? Why not ask their avionics guy
to look at it?
Part of building an experimental is making sure all the parts of your
airplane are working properly before you leave the ground. A simple radio
check before it leaves the ground uncovers your potential problem. Why
hasn't your test pilot (an ex-fighter pilot), suggested a path forward for
you?
Kind regards
Jim!

Can you all look at he enclosed photograph and see if you can help me
figure out how to get it working. My test pilot (an ex-fighter pilot) has
indicated that it is not working at all. He says the radio just blinks and
flashes like it is working (turned on) and pushing all the buttons doesn't
seem to do anything to get it working. He has had to use a hand-held radio
and refuses to fly again until the radio is fixed.
As far as I know, the radio in my plane has never worked. I have never
flown the plane myself, but I do not think it has ever been functional. Is
this a simple fix?

There have been problems with X-COM radios due to manufacturing issues.
These are being resolved, according to the website. They are now being
manufactured by NARCO, a well-known PA based company. Any radio shop should be
able
to remove it and send to NARCO for repair. If memory serves, your
installation was done with a factory supplied harness, so the fault has to be
with the
unit itself.
You might also email the factory and mention the symptoms.

much flying time is now on your aircraft. Actually, if you anticipate
flying a lot between now and Sun N Fun, add that estimated time to the total you
send me. And just to keep things from getting confusing, please also send
your N Number (or country registration) along with the type (Lightning or
Esqual) and total hours of flying time.
I will provide all of you the results of this poll when (and if) I get

| Subject: | Radio Interference |
Some comments from a guy on the Yahoo engines list who's been helping
folk out.
He's done extensive testing around the RFI that the Jabiru engine emits.
If I find the rest I'll post the link on here.
I did extra screening on my Esqual system and the radio still isn't as
good as my Jabiru.
Both have tail dipoles which should be a far better antenna than a
quarter wave fuselage one. However, I have been told of problems with
structure and even paint possibly masking the antenna in a tail.
Dave, what's a vhf-51?

Yes the bosch leads you found look to be the same as I used. They have a
number marking on them something like 365 however some leads had a
different number. look at the picture in the files, you can read the
markings there. The Bosch premade leads cost $6 each here
New Jabiru engines, on the website, appear to have similar leads fitted,
not the old red carbon ones.
Screening the coil leads can be by braid or spiral winding copper tape
over them. But I dont like the idea as its easy to get breakdown
especially the 3300 where moisture could track via the joint. the same
level of improvement is obtained with 2 ferrite beads to each lead. 3
beads is more than needed, if you want to make sure of it. The best
beads are hard to find now, the ones I got were ideal.

Thanks very much for the detailed feedback, I must have missed the
earlier explanation you made I'll have a dig back in Yahoo.
I've just replaced my plug leads on the 2200 plane as it's done 1060 hrs
and I was getting some breakdown. Not expensive as I made them up, but
the price of auto plug leads isn't great so I'll look into changing them
on my 3300 as that is the one with the worst radio.
When you say Bosch ferrite core helical resistance wire are these
standard leads or something different?
I've had a surf and come up with this page
http://www.bosch.com.au/content/language1/html/2253.htm
Doesn't figure on the UK website though.
Screening the coil leads would be by fitting a grounded braid?
Sounds like you've done some great work which it would be really good if
Jabiru picked up on.....

Subject: Re: More Radio Noise
Hi Clive,
Yes your idea of grounding the shields at the cockpit end does make
sense and I have tried it that way and with both ends grounded. But the
reason I say to only do it at the engine is mainly to avoid any
circulating currents getting to the electronics in the coils when for
instance you are cranking the engine with mags off or flying with one
disabled (because a rotor slipped and causes misfiring on that mag,
whatever. You then have a situation where the electronics in the coil is
subject to the voltage difference between the cabin ground and the
engine ground, with 200 amps starting current that may be 2 volts. Its
just not good practice. I flew my C150 for a couple of years before
discovering it had no earth straps fitted across the rubber engine
mounts (there should be 2) meaning the 400 amps starter current return
to the battery was soley via the throttle, mixture and various scat
hoses wires that connect to the fuselage! No wonder it was a slow
starter.
The jabiru charging regulator does put out some spike noise which can
make a pitter patter on the audio systems, but in my case its not a
problem and I dont have a large capacitor like the Rotax recommend. I do
have a large battery and its direct connected to the regulator both
sense and charge wires no switch contacts to cause trouble.
For eliminating the ignition noise, for my engine the most dominant
noise by a large amount, The best step was to replace the carbon film
leads (cars stopped using these after the 70's) with some Bosch ferrite
core helical resistance wire ones off the rack at our local car parts
store. I have no opportunity to test other brands, but assume Bosch
supply this lead to many european cars so its a matter of buying 8 leads
long enough to cut off the straight plug connector and crimp the angled
connectos on.
2nd step was to bead or shield the coil lead. This is a copper wire
lead. Some have said it can be replaced at the coil but if that was easy
Jabiru would already do it instead of soldering on an extension for the
3300. terminating these ferrite core leads is also harder to do.
putting the r plugs in last change cut my noise downn a little further,
but my static tests suggest the HT leads radiate the most noise. Avoid
adding more than the leads + the R plugs as its already over the normal
system resistance by then.
So other than trying the wiper to ground the flywheel, like someone in
Europe did, I dont think there is much more to do.
I have seen reports of
shielding the cowl with mesh or conductive paint
magnecore HT leads
ferrite beads on HT leads
filters on radio etc.
all not having any useful effect.
I suspect that some of the problem is that any one of those things
alone might not be notcable to the user, without the benefit or testing
in a repeatable environment. I used test equipment to find the best HT
leads and r sparkplug combination, and various radio frequencies with
known reference signals in flight, comparing the unmodified mag noise
with the modified side. The L mag is always slightly noisier than R, so
that has to be taken to account.
If you study the graphs of my files, and flick between them or print
them and overlay the traces, you can see the improvement made by each
type of lead, and the fact that the improvements are different depending
on the frequency being looked at. I have plots over much wider
frequencies, and the inductive leads are best overall, even better than
standard full shield aircraft leads (which are helical wire core, by the
way)
Its my belief that the coils will never be able to be totally
suppressed, and to do better would mean shielding the distributors as
well. but its more important that the engine is reliable. If the antenna
is already in the tail theres no where else to go.
Good luck.
Ralph

Hi Ralph, I was reading your post on radio noise with interest.
You suggest grounding the P lead shield at the engine end. I did it the
other way, grounded on the panel earth as I felt a cleaner shield would
be better and bringing the engine ground 'signal' into the plane would
be a backward step.
I did no end of shielding and have big cables on my ground circuits and
still have a ropey radio.
What's your thinking about grounding the P lead shields at the engine
end?
I'm open to any ideas to improve things and I suppose I could be taking
the interference that is in the P lead into the panel.....
BTW, the Antenna is a dipole in the tail which works very well in my
other aircraft (Jabiru).

I have an Esqual. a with jab 3300. My fix or relief came when I mounted
my antenna, vhf-51, inside the vertical stabilizer and used rg 400
cable. When it is stuck inside the fuselage only about 1/2 of it is
mounted vertical, this is ok if you are doing steady aileron rolls, just
kidding, so I thought why not in the tail where you get a total
vertical antenna and it is as far away from the engine as possible.I can
receive and send clear 100 plus miles Unicom frequency. I have a Garmin
SL 40.
Hope this helps Dave McC.

Plug lead material, see the picture in the 'files' on the bottom link,

Ferrite beads on the Coil HT, never heard of this or thought of it,
seems two leads help a third makes no difference. Seems a great cheap
and easy improvement.
Shielding the P, leads, we all probably know this but Ralph suggests
shielding is grounded at the engine end.
I did the opposite thinking I might import some RF into the panel area,
he also suggests using the shield as the ground for the mag switch,
can't see what difference that would make so won't change mine, it does
remove a wire so would do it this way in the future.
8mm Ferrite beads are the order of the day!
Then new plug leads!

James Hallam, who has a Twister with Jab 2200, has had a hell of a time
with
interference and I pointed him towards a UK company that manufactures
plug
leads for racing engines that employ the same technology used in the
Bosch
Oz leads. It made only a marginal difference, and not worth the =A3200
or so
quid he paid.
I have tried ferrites on the ignition coil leads and that was a total
waste
of time.
I don=92t know anyone who claims to have found a noise reduction from a
grounded shield on the P lead. But removing RFI is a black art and what
works in one installation can be hard to replicate in another.
I have come to the conclusion that there is no magic bullet. The best
thing
to do is what Jabiru do themselves and that is mount the aerial as far
away
from the engine as possible. Of course, if you can get a job at Jabiru
or
working for Jabiru, the RF disappears. Roger Lewis was deaf to it, I
wonder
if he can hear it now?
Cheers,
Paul

>From what I can see from the work Ralph has done the fixes are
associated
with:
Plug lead material, see the picture in the 'files' on the bottom link,
the
Bosch cable is shown. Link to Bosch leads on previous posts (aussie
website).
Ferrite beads on the Coil HT, never heard of this or thought of it,
seems
two leads help a third makes no difference. Seems a great cheap and easy
improvement.
Shielding the P, leads, we all probably know this but Ralph suggests
shielding is grounded at the engine end.
I did the opposite thinking I might import some RF into the panel area,
he
also suggests using the shield as the ground for the mag switch, can't
see
what difference that would make so won't change mine, it does remove a
wire
so would do it this way in the future.
8mm Ferrite beads are the order of the day!
Then new plug leads!
Regards, Clive

| Subject: | new soon to be option for the Lightning |
All Lightning enthusiasts,
As you might expect, Nick and the Arion team get lots of suggestions for
the Lightning. These suggestions range from such things as changes to the b
asic
design, things to add as options, and even things that would add another
flight capability for the airplane=99s operation. Being a very proac
tive group,
they evaluate all of the suggestions for the various pros and cons, and eve
n
do preliminary testing on some of the suggestions to determine if any shoul
d
be incorporated. Occasionally, someone=99s suggestion is determined
to have
great merit and that suggestion is then incorporated into the basis Lightni
ng
design, or into Arion=99s overall business plan. A little over a yea
r ago,
someone asked if it would be possible to put floats on the Lightning. Obv
iously
that is a very intriguing idea, but one that would require a great amount o
f
time. First you must design the floats and subsystems, then produce a
working prototype set of floats, and finally to flight test them: Too much
time for
the ever busy Lightning Skunk Works team to take on.
But sometimes potentially good suggestions have a way of getting done even
if the =9Cfactory=9D guys are too busy to get directly involved
. So, not to let
a good idea go to waste, the Virginia detachment of the Lightning Skunk Wor
ks
team has been hard as work in a hangar at Wakefield airport (KAKQ), with th
e
goal of producing a prototype set of floats for the Lightning. Primary
credit for the design and fabrication work of the first set of floats goes
to Joe
Mathias. Joe is an absolute master craftsman in all types of aircraft
construction and has built and restored several Oshkosh champion aircraft i
n the
past. Of course, Joe was ably assisted in this monumental task by his bri
de
of many years, Linda Mathias who built Lightning kit #20, N59JL. The
prototype set of floats for the Lightning are constructed of marine and air
craft
quality plywood, but once the design has been flight tested, they will be u
sed
to produce a mold so that follow on floats can be quickly duplicated out of
fiberglass. The photos below (photos by Russell Hornsby) show the floats
mounted on the test aircraft, N31BZ, Buz=99s highly modified Esqual L
S (Lightning
Stuff). Heck, I might change the LS to LSS to mean Lightning Stuff Seaplane
.
This photo was made on the initial roll out day, but since that time, water
rudders have been added to the floats and are tied directly into the aircra
ft=99
s rudder cables. We have also built a dolly that will allow the airplane
to takeoff from a =9Cland base=9D. The dolly also makes it easy
to move the
airplane around the hangar. Initial water landing and taxi testing is plan
ned
for a secluded cove in the nearby James River. We are planning to make th
e
initial water landing later this afternoon, April 1.
Blue Skies,
Buz
