Denny,
Not sure if you consider Chicago a day trip, but you're more than welcome to
a ride out here. There are 4 Kolbs including mine. 2 with 582's & 2 with
912's for towing hang gliders. We fly out of Cushing Field about 50 miles
west of Chicago.
Chris

--> Kolb-List message posted by: <rowedl@highstream.net>
Here is a question for any electrical engineers on the list.
I recently safety wired my sparkplug wires to my NGK resistive spark plug caps.
This was done over both ends of the boot with a double loop at each end, one over
boot and wire, the other over the boot and cap. I also did this at the ignition
modules as they are the exact same type of connection as the plug caps.
I used one continuous piece of safety wire at each plug wire end and acheived a
very nice strain relief effect, not to mention it looks super.
Here is the problem. : Now I am wondering if the shorted coils wrapped around
the plug wires could cause a parasitic inductive load on the spark impulse and
possibly cause a reshaping of the wave form.
What I basically have is a one to four tranformer coupling between the plug wire
(primary winding) and the safety wire secondary winding.
I hate to go with zip tyes in place of these if the wire won't cause a problem,
but if there is any doubt, the wire is outa there.

Kolbers & FireFly Owners,
I converted the aileron trim mechanism to a system that does not go out side the
cage. A little lighter and safer that the old system. It can be seen on the
bottom at:
http://www.thirdshift.com/jack/firefly/firefly51.html
Since I have been flying a little, I discovered my new angle of attack meter is
not working as described at:
http://www.thirdshift.com/jack/firefly/firefly85.html
When I first researched this technique, I was placing the strings much lower and
they worked great. Then I overheated the Victor 1+, and while waiting for parts
I reworked the system and installed as described. I placed the strings higher
on the windshield so that I could see them easier. But in doing so I moved
them up on the round part of the windshield and away from the slab sides.
Unfortunately, this new position made the string very unresponsive to angle of
attack. I will go back and research where to put them to get better response
and up grade the page.
It is snowing again here today, so I put up some photos and explanation for some
of the coolant plumbing on the Victor 1+. After frying the engine, I am almost
paranoid about seeing or knowing that there is coolant in the engine. These
photos can be seen at:
http://www.thirdshift.com/jack/firefly/firefly86.html
This is a poor substitute for flying, but it is the best I can do for today.

Denny,
In the old days I wired the plug caps with safety wire until I got one
underneath one of the plugs and tightened it down. It made a channel in
the softer aluminum head (ouch). Then, I got worried about the wire
shorting out the spark so I found a better way. Drill two small holes in
the cowling near the plugs on either side (about 4"-6"). Run a couple
strands of safety wire through each of the holes and twist together. Run
a plastic tie wrap around the plug cap and safety wire to hold the plug
caps down. This works much better.

Try fastening your static line below your pitot tube.You can
tape them
together if you want.Take the 1/4 in static tube,solder the
end shut and then
drill 4 small holes in the sides of the tube,two on each
side about an inch
apart.Mine tubes are 4 inchs below the belly anchored to the
floor ,but they
should be fine both through the nose.The static is 1 inch
shorter than the
pitot but that might matter either.It seems very accurate.
============================
on my first attempt on a peto static i put them both out the
front and the asi read low.... i put them out the bottom
about 4 inches down and it fixed the problem.

Jeremy,
No. I just wanted something better than a Rotax 447 on the FireFly. Simonini
nor any engine manufacturer can not be held accountable for someone mounting their
engine on a FireFly. It is really up to the designer or, in this case, the
builder to come up with a suitable mounting configuration. So what you are
seeing are the trials and tribulations of someone trying to keep his FireFly
within the ultra light vehicle regulations with the mounting of a new engine.
In trying to keep off weight, I built some things too light and they broke.
In most of the cases no one heard about it because it did not fry the engine.
But after about ten hours on the engine, I thought I had seen the last of the
early failures, and I was ready to go across country, but I was wrong. The good
thing about it is that each failure made me think it through again and most
of the time the solution was stronger and lighter than what was before.
The rebuilt engine is running very well. I do not know how well because I have
not been able to record any fuel consumption data. But the engine has used two
gallons of fuel since it was put back together and this includes 50 minutes
of flight time. This indicates an average fuel consumption rate of 2.4 gph.
But if one subtracts the fuel used for warm up and taxiing to and from (four
times) the taxiway I use as a runway (.08 gallon on a warm day), the average for
50 minutes of flight time would be just over 2 gph. If I had a better figure
for fuel used during warm up and taxi out for cold weather, actual in flight
fuel consumption will fall below 2 gph. This is very exciting to me and I want
to find out just how good this engine is. During this time I was flying a
700 foot pattern and shot 10 landings.
Since I sent in the last message I have been at work trying to get a little microphone
hooked up to a small cassette recorder so that I can record data in flight.
I finally got it to work, and I have to work up a throat mike holder for
the microphone to keep from getting too much engine noise on the tape. Then
I will be able to record ias, gps speed, engine rpm, and fuel flow rate. When
I get the data, I will put up another plot. Right now the FireFly on downwind
leg, will fly about 65 mphi at 5200 rpm and the fuel flow meter will show about
one gallon per hour. For me this is very exciting, because it means I can
fly to my EAA meeting and back and not have to truck gas to be sure I can get
back. It also means I will be able make cross countries without spending more
time on the ground getting gassed up than in the air traveling.
All of this effort helps me to appreciate all the work that has been done in developing
the FireFly, and to empathize with anyone who is mounting a non-Kolb
specified engine on their project. But for all those who say why bother changing
what Kolb has already designed, I say why not? Now on to getting my strut
fairings mounted to see if I can get a few more mph and lower gph even more.
Will it all be worth it? Time will tell.
I apologize for the ramblings, but the skiff of snow has turned into about six
inches and it is still coming down. I need to get back out and shovel so the
wife can get into the drive and the garage.

Ralph,
You missunderstood what I was describing, I am safeting my wires to the caps
and ignition modules, not the caps to the engine. Trying to insure the wires
will not pull out of the plug caps or CDI modules.

Dear Santa,
This Christmas I would like a new Kolb Mark III X-tra with the 912S engine and
Warp drive prop. If your elves can manage I would also like it to be fitted with
EIS and painted in plain white. I know you like white and a touch of red would
be ok if you see fit. I know your on a tight budget as most of us are but
hey your Santa! Don't bother trying to fit it thru the chimney even though the
wings fold. I have been a very good boy this year and if you see fit this would
make me very happy. Plus the folks at The New Kolb aircraft company and others
that have Kolb aircraft have assured me that they are safe and fun to fly.
Not to knock you set up, with the reindeer and all, but you might like to look
into one yourself with skis!
I know that you are close to Jesus and all and please don't let those folks in
Australia get you down with all their anti Santa BS.
Perhaps if you outfit yourself with a Kolb he just might want to join you for a
ride!
Thanks
Paul
ps. I will have the usual snacks out for you (crawfish & your favorite beverage)!

| Subject: | Throttle and choke cable splitter problem averted |
--> Kolb-List message posted by: <rowedl@highstream.net>
Dual and triple carb two stroke pilots.
I think I avoided a potential puzzler today.
I have three bing carbs on my 690L and am using the three into one cable splitters
on both, the throttle and the enrichers.
Today I decided to wrap the individual sets of three cables with spiral wrap from
where they come out of the top of the splitters up to the point where the begin
to separate to each carb, (also could have used zip ties.) (I spelled ties
right today}
Anyway, after I finished, I shook the set of throttle cables side to side to simulate
the rocking of the engine when running. Upon doing this, I could hear
the slides in the carbs pinging lightly off the idle stop screws. This happened
because the cables where tied together by the spiral wrap so the ends were rocking
up and down in the caps of the splitters causing the slides to alternate
up and down slightly. I figured the enricher plungers could be doing the same
thing, so I removed the wrap on those too.
I am sure this would have caused a real tough tuning problem down the road.
Bottom line, I don't think its a good idea to tie the sets of throttle or enricher
cables together where they exit the splitters on the carb side.

If the plug wires are properly screwed into the plug cap and coil I cannot
imagine them ever coming loose. I would be more concerned with the safety
wire causing a problem. Just my thoughts.

I don't think you oughta wring yer hands over this (maybe) "transformer"
problem. Why not try it on your car/truck? To see whether there is any
actual inductive pickup, wrap a coupla turns around one of yer truck
plug wires, ground one end. Bend the other end so that it is close to
grd metal. Wait for nightfall. Start engine.See if any spark jumps off
the ungnded end. Since it's dark, feel around till you find the end. Ck
to see if yer eyeballs light up. Ck rpm. Then grnd the open end. Ck rpm.
Rationalize.
Some tachs get their info from a twisted wire around a plug lead.
Doesn't bother the plug.

You are right again. I remember ending up with 10
or 15 wraps of wire around the plug wire for my
Firestar Tiny Tach. Even then it would act up and
make me angry. hehehe
Now, please decipher the EE49 (before sparks) for

> Denny n folk....I may not understand exactly what's being said here but I
for one HAVE had a problem with the lil smooth coke bottle metallic cap
screwing itself back off the top of the spark plug and moving far enough away
from the threaded post at the top of the plug to make my one cylinder
useless......while I was at the 500 foot level!!! Fortunately I was high
enough and close enough to the field to Kill the engine which was vibrating
wildly, I aimed the ol nose right at the power lines I had to pass over...saw
I had enough speed....and came in for an eventless dead stick landing. Just
another day in the life of;.......... etc.
The problem was that the cap was screwable. If it were part of the plug head,
I don't think the wire terminal of the ignition lead would have departed the
coke bottle top of the spark plug..at least it never has yet.
So shit happens and fortunately I was in a position to glide it in.
I am pretty sure if I had a tight safety wire system on the ignition wire the
plug would have continued to fire in spite of the cap coming off the top of
the plug. I am also pretty sure that if the plug did not have that lil coke
bottle cap screwable on the top of it the wire probably would have never
come 0ff either. dunno bout this fer sure, but this is what I think Denny is
trying to protect against.
One thought ..... a transformer requires a circuit on the secondary side
to make current flow...otherwise only a secondary voltage would exist
in the secondary
( safety wire) therefore no spark energy is lost if no current flows in
the safety wire. ie. the way the safety wire is used would determine if
it affected the spark shape against time. There is the potential for a poor
transformer there but it may not drain any energy from the plug wire
if it is not a circuit.

You can order spark plugs from CPS and other U/L dealers where the plug top
is not a screw off aluminum top, but a solid steel top of the same shape as
the screw off aluminum coke bottle shaped top. They cost more, but worth
it. The tops do not screw off, they are an integral part of the plug.
There is another reason to use those instead of the plugs with the aluminum
screw off top:
I discovered that my brick red phenolic spark plug caps (The ones that are
on the high tension leads from the coil) were wiggling around on the spark
plugs. This was because the wire clip inside had vibrated it's way into the
NGK aluminum spark plug screw off top, and was now free to wiggle around in
the area it had chewed up.
Installed now spark plugs and after a few hours, the situation repeated
itself. Went to solid steel topped spark plugs and solved the problem. I
suggest not using spark plugs with aluminum tops for that reason also.
