| Subject: | Re: Landing distances |
Reminds me of landing at one of the jungle strips I used to fly into in Papua New
Guinea years back. It had an upslope on it with the parking bay about two thirds
of the way up the strip, but that last third was almost level so you could
actually land downhill if you were lightly loaded, providing you put it down
right at the threshold and jumped on the brakes. The Pilatus Porter turbo prop
with beta range and reverse thrust could stop before the turn off but the rest
of us in our 206's, aztecs, etc usually went past a bit and had to turn around
and taxy back. It developed into an unofficial short landing contest with
the winner being acknowledged at the bar the next evening.
There was one of those push/pull twin boom cessna 337's (I think) made an approach
there one day, first day out after major maintenance. He touched down right
on the mark and stopped short of the turn off ! Fantastic stuff. Won the prize
that week.
Slight problem though, the reason for the short landing roll was that is was not
a roll, but a skid ! He'd forgotten to put the gear down and the back of the
drag curve, full flap approach required enough power that it did not not to trigger
the warning horn. It turns out he had been flying the fixed gear version,
the 336, earlier in the day.... oops !
The competition was called off after that as it was thought nobody could trump
that effort .... particularly as it was the chief pilot at the time who did it
!!!! [Embarassed]
Cest la vie ....... and no it wasn't me !

If you want to loose plug problems altogether, put BR8EV or BR8EIX's in your 2
cycle Rotax that uses B8ES plugs.... the R doesn't matter with those plugs. I
was changing B8ES's every 10 hrs when I first flew the Firefly in 2002. At that
time there were only BR8EV (Palladium) plugs available from NGK. After installing
them I changed plugs at 75 hrs as a preventative measure, even though
it was still starting on the first or 2nd pull and running perfect and they looked
great.... I'm sure I could have run them 100hrs with no problem. Now the
Iridium plugs (IX) have pretty much replaced palladium and are as good or better
but I sold my plane before getting much time on them. These plugs are more
expensive ($7 or $8 apiece) than B8ES's, but there's a reason for that.... they
perform much better and last way longer. I did the same thing on my motorcycle
and am seeing the same results... much better cold weather starting too.
The small electrode must have something to do with it.... more concentrated
spark I suspect but I'm no expert on plugs, just know from experience that these
work much better and last a lot longer than the B8ES's.

Regarding spark plugs for the 503 This is off the Aero Propulsions Web
site..
Spark Plugs:
The recommended spark plugs are the NGK B8ES or BR8ES.
The "R" denotes a resistance which helps suppress radio interference.
The use of spark plugs with a solid tip, rather than the screwed-on tip,
is mandatory. The latter can unscrew itself in flight and dislodge the
spark plug connector cap, creating an ignition failure.
Spark plug gap:
Allowable range: 0.4-0.5mm / .016-.020"Optimal: 0.45mm / .018"
The gap can be reduced to its allowable minimum to help starting in
very cold conditions
Things to be avoided:
Other spark plug models and other manufacturers' equivalents Screwed-on
tips Unverified spark plug gaps

Frank, I went to the hangar today. I put seafoam into
the back cylinder and let it soak while I replaced my strobe light. I
then ran the 447 on the plugs that were in it already. My RPMs were at
6030 tied down. That was up from 5970. I put in new BR8ES plugs and
fired her up.She went right on up to 6270 rpms. That is only 20 rpms
less than what I got when I originaly set the IVO. Ran great on the
way to another airstrip about 9 miles away. The old plugs were very
clean looking with a hint of light brown grey on them, but the new
plugs bumped the rpms up another 240 . You were right on! Thanks for
your input!

Just an added note.
Be careful switching brands of spark plugs with different brands of
spark plug wire caps. I ran into a problem with Bosch plugs many
years ago, when they first came out with a platinum tip plug. Great!
A plug that would be better than the BR8EV and for a fraction of the
cost. Plug worked great, but not with the NGK plug wire cap. Had to
get some Bosch plug wire caps that were molded to match the ribs on
the Bosch plugs. This kept the caps from wobbling around on the spark
plug.

Mark:
Eric Tucker, Rotax two and four stroke "guru" explained to us in the
last class I attended a year ago, that Rotax had a difficult time
maintainer suppliers for any length of time. For example, the
question was asked, "Why doesn't Rotax put fuel injection on its 912
series engines?" Answer was, lack of a supplier that would stay the
course. It cost a great deal to certify an engine and its
accessories, which does not affect us UL and experimenters, but does
cost them a mint for their certified line. Uncertified parts for
Rotax are the same as certified except the certified part has a
serial number to track it, and ours don't.
Rotax has been using NGK plugs since the very early years.
I had good luck with Bosch WR4CP Platinum plugs and metal jacketed
Boxch plug wires for a 4 cyl Volvo, about 1975 vintage. Back in the
mid 80's that would make two sets of wires for a 447. Now it will
make one set of wires for a 503 or 582. Probably still available and
cheaper than Rotax supplied parts. This plug worked great on my 447.
Never fouled another plug after I started using them and they lasted a
very long time.

Not a good idea at all. The problem is not making it stay on, the problem is
that you are using aluminum in a place that requires steel. The solid top
spark plugs have a steel top, while the screw on spark plug tops are
aluminum. The problem arises when the Rotax plug cap is snapped onto the
aluminum spark plug top. There is a hard steel spring wire in the Rotax plug
cap which holds it on and provides continuity. When it is snapped over the
aluminum plug top, the engine vibration causes it to quickly eat it's way
into the aluminum. Even though you deform the screw-on aluminum top, it is
still going to be chewed up/worn away in a way that the solid steel spark
plug top will not. You will end up with a Rotax plug cap full of aluminum
dust and a wobbly poor connection. Eventually you will have to buy a new
Rotax plug cap because the aluminum crud will ruin it.

I'm a little confused about which NGK plug works "best" in the Rotax engine. What
are the upsides and downsides of the resistor type BR8ES NGK Spark Plug? I'm
figuring the upside is the ability to reduce noise in my radio. Am I trading
off noise for a less reliable spark plug?

Probably not less reliable. If it was less reliable, Rotax wouldn't tell you
to use it.
But the hotter a spark I can have, that's what I want. If I don't need a
resistor plug, then I won't use one.

John M:
There is not enough difference in performance between resistor and
non-resistor plugs to measure. Most engines are equipped with
resistor plugs. I know the 912 series engines are factory equipped
with resistor plugs. Rotax would not install a spark plug that was
less reliable than another, especially in a two stroke. The NGK
resistor plugs and Rotax have been operating many, many successful
hours.
What does Rotax put in the two strokes now days?
My 2 cents worth.

Brother Richard,
The heat range of a spark plug does not refrance the heat of the spark but rather
the heat transfer of the spark plug to the cly head as Eric Tucker explained
to me in the 4 stroke school If i remember it correctly :D

Assuming that you have an ignition system in perfect condition, I'm sure
it's not worth measuring. But if one of us might some day have the
remarkable misfortune to have an ignition system that is putting out less
than it should, (Unthinkable! Rotax ignition systms are surely failure
proof) or leave a spark plug in too long and let it get cruddy (Never
happen, GI) then you might be glad to have as little resistance in your
system as possible.
Especially if you don't need it, which is my whole point.
Here is a link to the difference between resistor vs non-resistor plugs:
http://www.ultralightnews.com/enginetroublshooting/resistorcapsandplugs.htm
Here is a line to the CPS tech page on plugs
http://www.800-airwolf.com/pdffiles/ARTICLES/part9.pdf
-which says that using both a resistor cap and a resistor plug can cause
problems.
And which I have experienced in the past.

Didn't mean to slam a door on you, such was not my intent, tho it
sure sounded that way when I re-read my reply. My apologies.
Often, advice from such sites must be evaluated critically.

This is correct. A hot spark is a spark that I can see jump a big gap in the
daylight as opposed to a cold spark that is so wimpy it can only be seen in
the dark, and may or may not fire the plug. Having a hot spark has nothing
to do with heat range. Apples and oranges.

God's-own-Lightning would be a welcome change from the
anemic flicker we now enjoy. Just look at plugs taken from a
modern coil-on-plug vehicle when the owner actually takes the
100,000 mile plug replacement interval as gospel...electrodes
are probably absent and/or reduced to nubbins but still light the
fires reliably....not efficently, but still......

I was impressed with the CPS article on plugs. I think I'm going to order some
non resistor plugs just in case.

just as
| I know what stock Kolbs are like. But if that is all that matters,
why do

Richard:
The CDI is super hot. If you let a plug get cruddy enough to foul, it
ain't gonna make any difference if it is resistor or not. Now days,
if you foul a plug, you better not be flying cause you got a serious
problem.
Now..............if you want to fly with a non resistor plug.
Great!!!
I prefer resistor.
You probably light up the airport when you crank.

PS: I will sleep better tonight because you know what comes in Rotax
and stock Kolbs. However, to change something for nothing can not be
too gratifying. I have certainly done that many times when I found
out my idea did not work as I thought it would.

How often does one rebuild a carburetor? My engine is how 7 to 8 years old, Rotax
503 DCDI with 190 hours. The carbs work fine as far as I can see.

You might check the date on the CPS publication. Sounds to me like it
was written back in the early days when we were flying with point ign
and not CDI which fires through peanut butter.
As far as California Power Systems goes, they have a a lot of articles
written by Mike Stratman who owns the company and makes lots of money
selling you all parts whether you need them or not.
If you have questions reference Rotax engines, why not check with the
source, Rotax? That's what I do.
A CDI system either works or doesn't work. There is no in between
like the old point system.

Usually, the parts that wear in a two and four stroke carb are the
little tangs on the floats, the little arms on the float lever, the
posts the floats ride on. Also the enricher valve.
I check mine periodically. If they look pretty worn, I replace the
worn part. Don't do it very often though cause Bing parts are out of
sight.

Yeah, it's so super hot we have to run a plug gap of .020 max
Whoo Hoo
My wife's motorcycle runs a bigger spark gap...
And as far as lighting up the airport? If I can't hear hash on my home made
recycled radio system, why should I think it would bother other people with
a good system? Anyway, no complaints in ten years.

Hi, I used to own an original firestar with a 377. Take off was never over 125'.
Landing about the same maybe a little longer.

I second the opinion on the fairing. I've always wondered why someone
doesn't design a fairing for the 503 in a Firestar-type installation. Seems
like you could pick up 10 or 15 mph, considering how draggy the unfaired
engine appears to be.

Roger L:
I'd go broke rebuilding carbs if I built them every 200 hours. More realistically,
take a look at them every 200 hours.
Also of extreme importance for two and four stroke carbs is to pull the float bowl
and check for water and contamination. A drop of water will turn into a lot
of crud that can shut down a two or four stroke.

REF:
I went to the hangar today. I put seafoam into the back cylinder
and let it soak while I replaced my strobe light. I then ran the 447 on
the
plugs that were in it already. My RPMs were at 6030 tied down. That
was up
from 5970. I put in new BR8ES plugs and fired her up.She went right
on up to
6270 rpms. That is only 20 rpms less than what I got when I originaly
set the
IVO. Ran great on the way to another airstrip about 9 miles away. The
old
plugs were very clean looking with a hint of light brown grey on them,
but the
new plugs bumped the rpms up another 240 . You were right on! Thanks
for
your input!
-----------------------------------------------
Ed,
Sometimes it is simple, glad it worked. I've got to try Richard
Pike's non-resistor plug idea too, would be great if it would work for
me. (I may experiment with his safety wire clamps again also, maybe my
tubing was old or below par. Richard's web site is full of good info!)
