- Does anyone have any idea of how many Kolbs have been-produced of eac
h type, both by Old Kolb and New?- And about how many are still-under c
onstruction?- Just curious.

| Subject: | MkIII antenna location |
Boyd and Larry=2C
Thanks for the detailed responses. All this information is helping me co
me to a final decision where to locate it.
As I said before=2C I'm leaning toward the fuselage=2C underneath and rea
rward (below the front of the boomtube). This seems to be pretty close to
where Richard Pike located his=2C and confirmed by Larry that it worked pre
tty good.
Presently=2C my plan is to build a dipole antenna=2C and make the groundp
lane out of 1/2" wide copper foil strips=2C in the shape of an "X". The BN
C bulkhead fitting will be centered on the X=2C where the 1/8" steel rod ma
st is fastened.
My final design seems to be a combination of a couple of other typical ai
rcraft radio antenna designs. (mast of the dipole Scott showed us=2C groun
dplane of common base station type design=2C etc.) Unless new and better i
nfo comes along=2C this is what I'll likely go with.
Locating the antenna at the top edge of the windscreen may not be a good
location for me. I had planned on putting my Garmin 296 antenna there=2C a
nd I understand there may be RF interference problems having two different
antenna types near each other. Belly mount antenna seems to be the best ca
ndidate=2C so far.
Putting a dipole out on the wing's leading edge would be the easiest=2C a
nd would probably work the best=2C but it would also look the dumbest=2C IM
O.
Thanks again to you guys that have responded to my request. You've been
very helpful=2C and am helping me get this figured out.

If anyone can explain the ins and outs of why a capacitor is necessary and
what it does, it's him.
Rick Girard
>>>>>>>>>>>>>>>>>>>>>>>>>>
I see that no one else has given this a go,,,, so I'll try!!!
a capacitor is made up of 2 metal plates separated by a non conducting
film,,, with 1 plate Pos and 1 plate Neg.. When attached to a voltage
source that is not regulated ( moments of voltage spikes followed by moments
when there is no power) when hit with a voltage spike works much like a
battery to absorb the spike and the associated current, but it works a bit
different. In a battery the voltage in the circuit has to rise in order
for the excess of electrons to enter the battery and cause a chemical
reaction ( charges the battery). But in a capacitor the current will
flow into the plates before the voltage has time to peak. The capacitor
stores the electrical charge much like a battery. But it acts much quicker.
And during a moment when there is no power from the source, the capacitor
gives up its stored energy to keep the current flowing smoothly. During
this time the capacitor is partly discharged creating room to absorb the
next spike.
If I could use my plumbing experience .. And make an analogy that is all
wet, it may paint a better mental picture.
Suppose we have a garden hose shoved down an over flow pipe. If the hose
is turned on to half speed, The amount of water in the overflow is
equal to the water in the hose.. If someone starts to turn the hose faucet
on, off, on, off, on, off, on, off. the water flow in the overflow will
follow the surges.
Now lets take the hose out of the overflow and place it in a tank with a
overflow, with the hose at half speed the water in the tank will rise
and the amount of water going down the overflow will be equal to the flow
from the hose, now if someone starts to turn the hose on and off ,
the excess water in the tank will cause the level to rise slowly and it will
slowly increase the amount of water in the overflow, and if you turn the
hose off for a moment, the water in the tank will continue to run down the
overflow at a slightly slower rate. All this time the outlet flow in the
overflow will go up and down but it will be more constant.
Now increase the size of the tank to say a swimming pool. ( a larger
capacitor) and the surges in the overflow will be even less.
Now how does this affect us in our kolbs. Lets compare the flow of water
in the overflow to the volume of our radios. A constant volume is much
easier to listen to.
Told you the analogy was all wet.
Do not archive.

Mike what you are describing is a quarter wave antenna with an X shaped
ground plane. A di pole ( di meaning two) is a radiating element with
one ground element usually mounted in a straight line, and in our case as
vertical as possible.

Boyd=2C
Yup=2C you're right. I got too loose with my labels. I meant quarterwav
e.
On the aeroelectric list=2C a guy suggested checking out Bob Weir's (from
Kitplanes fame)website. I am very familiar with Bob Weir's designs=2C and
in fact=2C I built of the copper foil antennas already=2C back in 2001. I
built it with the intention of using it on my MkIII=2C but then recently s
ort of changed my mind. Now=2C I'm back to using it. It seems like it wil
l be the best one for me=2C after all.
Thanks to everyone for their help.

No it will not hurt. The installation manual on the 912 says to install a
22,000 uf 25 volt capacitor between the positive output on the voltage
regulator and ground. That should be enough to smooth out the power. if
you went 40,000 uf it would it make it smother than smooth,, it wont
hurt but it may not do any additional good., going too large should not
hurt unless you are cramped for space and weight. If a person wanted he
could install one near the voltage regulator and one near the radio. If
you can only find a capacitor of half the desired amount,,, put two in
parallel, that will cause the values to add. On the electrolytic type
capacitors they are marked with a + and - make sure they are installed
correctly.
Two capacitors of the same rating mounted in series will give you the value
of 1/2 of a single capacitor.

Your invited to my second annual birthday fun fly weekend. Located at Ace
Airfields in Farnham Va. Camping under the wing fun with food ,music &
great fun with other pilots like yourselves. The fun starts on July 9-10.
My airfield is located at GPS 76*36.071w & 37*56.500n close to the bay. The
runway is a north< south orientation it is a 2000 ft grass strip with a line
of trees on the west side of the field. When you approach from the north use
left traffic from the south use right traffic. Stay over the trees on the
west side of the field.I will be useing craf ch#12300 to help if needed. If
you choose to drive use GPS king ln farnham va or give me a call
(GREG) (804)450-6200 Hope you can attend.

Sorry, but now I am confused. As near VERTICAL as possible?

| Subject: | Fire Fly with everything you need. |
A friend of mine needs to sell his Fire Fly due to health reasons. Below
is a description of what he has.
-------------------------------------------------------------------------
-------------------------------------------------------------------------
-------------------------------------------------------------------------
----------
Trailer two year old Hallmark 26 foot, oversized, insulated, finished
interior with cabinets, AC/DC lighting. Soft-Ride suspension, Low Miles.
Excellent tires. Easy to heat with a Coleman Camp heater or electric
bathroom heater.
Firefly first flown two years ago. Wings built by Dennis Souder
(Original Kolb) and dry-stored.
Fuselage built as Oshkosh Display Demo -- serial number UL 001. Before
the FF production series. Travis and Brian says no changes were made in
the production. This is the original.
No damage except a very small neat smooth patch on one wing. I dropped
the wing in the wind.
Icom Radio with PPT and Lynx Headset and charger. Lynx helmet.
BRS-VLS chute. Two years since new.
Black Max brakes.
400 X 6 tires, mag wheels.
EIS, compass, ASI. Mounted in instrument pod that brings the panel close
enough to easily reach while harnessed.
Hardware for winter canopy
IVO three-blade
140 hour engine with new rings. I didn't need rings, but I was
encouraged by CPS to replace them.
Recent teardown and de-carbon. (about four or five hours on de-carbon)
Five and ten-gallon tank with frame fitted to match either.
Recently ramp-checked as LEGAL Part 103, I have the papers.
Rigged straight and level.
I have flown at Reno-Stead a few times since I lost my strip, and I
don't feel safe with the amount of traffic over there. On last flight it
took almost forty minutes to get airborne.
I must sell it or park it, as the nearest other alternate field is
outside my affordable driving range.
