This weekend,Saturday, Novemember 21, we will be having a BBQ at Quincy
Airport off of Hwy 12. Due to liaibility issues, this is NOT a fly-in,
just a bounch of people interested in aviation getting together and
having fun.
See you there,

Would you consider rebuilding a 582, when its time. I live 15 minutes from
Green sky Adventures the oldest Rotax dealer in the USA and maybe having him
rebuild but that might be about $1000 or more. How much trouble was it
actually to rebuild I'm thinking about going to the Votec for small engine
repair to get ready for when my engine goes TU. What do you think.

Mornin Gang:
Happy Monday.
I can totally empathize with the above statement and situation. I felt the
same way when I pulled the hide off the wings of my Ultrastar to rebuild
after a wire strike. I guess tearing up airplanes is something I have to
accept if I am going to participate in this sport, whether I tear them up,
or Mother Nature.
I watched two Twin Stars at Florida Flying Gators Airstrip get trashed in
Nov 1987. One man made a mistake that took out a brand new airplane, that
later became the Sun and Fun Lt Plane Grand Champion 1988. He didn't do it
on purpose, just got a little over zealous and made a poor decision.
Richard Swiderski was there. In fact that is when I met Richard with his
Ultrastar. No one was hurt physically, but there was a lot of mental and
financial anguish. I felt for both individuals and thanked God it was not
me who made the mistake or who was in the line of fire and had a new
airplane broken.
I have totaled every airplane I built (three) and rebuilt all three of them
at least once. The MK III has had three tail booms. Now that is a job in
it's self, just replacing a tailboom. A heap of stainless steal rivets to
drill out. If you have to drill out a pop rivet, carbon or stainless steel,
take a mandrel that has already been pulled and use it to push the mandrel
out of the rivet you intend to drill. Stick it in the hole and give it a
tap with a small hammer. Then drill, much easier than trying to drill thru
a hardened mandrel end. If the rivet wants to spin, make a little tool with
a flat sharp edge, ground out a little to stick under the edge of the rivet
head. This will put the brakes on the spinning rivet and allow you to drill
carefully.
I need to replace elevator and rudder hinges, but procrastinate for the very
fact that I hate to get started drilling a zillion rivets. Oh well, one of
these days.
Later on,
john h

Funny you should mention that. I watched the midair collision of a firestar
and a Pteradctyl (?) at hoeseheads new york back when they used to have annual
flyins. Both pilots and planes survived. The Kolb guy wasn't looking up and
the other guy wasn't looking down.

Frank,
These motors are simple. Yours is a little more complex than mine, but
anyone with any mechanical skill/understanding can work on them. It
took me less than two hours to disasemble and reasemble when I honed the
front cylinder. The first teardown took about an actual 10 hours total.
Now, on the other hand, I like to work on things. If you are the type
that doesn't enjoy this type of one-on-one with your aircraft, I would
recommend subing the work. I now have a pretty good understanding of my
realiable though. Green Sky comes highly recommended. John H. told me
about them, and I have had good technical assistance from their
mechanics. I look at it this way: Give a man a fish and he eats for a
day, teach a man to fish and he eats for a lifetime. Same goes for
engines. I could pay someone to rebuild, but would gain nothing.
Learning to rebuild myself gives me the understanding, experience, and
ship back and forth, or wait in line to have my stuff worked on.
One day I hope to have the same understanding of airframes....

Sounds quite reassuring, when can we fly. : )
Just kiddin'. I guess that says alot for the structure of the KOLBS in
a crash, or the pilotage of John. I think it was probably a little of
both.
I would like to hear the stories some day John.

A similar point, and this can go both ways of course... If you worked on
it yourself, you *know* the degree of quality and care that went into it.
BTW, Rut, I'm impressed with your speediness on getting back into the air.
I would have spent twice the time just trying to decide what to do.
Good job!

My 447 has this baffle and the rear (PTO) cyl runs ~30 degrees hotter.
I ground down the baffle a little bit to allow more cooling air back to
the PTO. It made practically no difference, maybe 10 degrees (measured
at the typical plug base anyway).

Hi Rut and Gang:
Thanks for the personal invite. I have the B B Q and Quincy on my calendar.
Haven't flown into that airport for a while. I like flying down that way,
it is where I grew up (TLH) and the turn around point for my first long xc
in my Ultrastar in 1984. Time is flying!!! Boy we've gone a long way since
those days. Never would have in my wildest 1984 dreams invisioned the
flights that my little Kolb airplanes have taken me. They all started with
dreams and ended with reality.
I'll try to make it to Quincy, weather permitting.

BK and Gang:
Breakin was not a requirement back in April 1994 when I started flying my
912. Has that been changed to a breakin procedure like the two cycles?
How bad is the leak? Can you see fuel pouring out of the air filter? Or
are you getting fuel residue on engine from fuel vapor standoff from the
carb? This is a problem with my 912 and significant others I have come
across over the years. Problem is caused by airflow over the engine from
the prop and from flying. Sometimes it is the right carb, sometimes it is
the left, sometimes it is both. A lot depends on how the aircraft is
trimmed in yaw. My eng has no oil leaks, but the fuel residue keeps the eng
nasty most of the time.
How to cure it? Turn the engine around and make a tractor out of it. That
is the way the eng was intended to be used, with carbs flying backwards, not
forwards. The same or similar bing carb is used on BMW motor cycles with no
problem, but they fly backwards. I was having carb problems in Dead Horse,
Alaska, temps in the high 20s and low 30s. A German on a BMW rode up the
Dalton Highway but had no carb problems. What's the difference? My carbs
go one way, his the other.
Thought about placing aircleaners in fuselage connected with airtex hose or
something similar. Haven't gotten around to that experiment yet.
Sorry I can't help any more than the above. It is a good eng. Mine is
working on a 1,000 hours (983 hrs as of yesterday). Still performs as well
as when it was a young pup.

John; Does this mean that "excess fuel from the vapor standoff" is coming
forward through the carbs/filters and sucked back all over the engine? And
this is considered "normal" for pusher applications because of how the
carbs are located? The ram-air entering the carb is not strong enough to
keep the fuel vapors from exiting forward trough the airfilters?
How to cure it? Turn the engine around and make a tractor out of it.
This is not an option for a MKIII

john h
Is it possible to turn the intake manifolds around on the engine so that
the carb sits on the backside of the manifold and "going backward" same as
the motorcycle? The drawings(topview) I am looking at in the CPS catalog
suggest that this maybe possible.(I am having a ball with this one!)

Hi Listers,
Al Mojzisik from the RV-List posted the message below to the RV-List
today. Besides making a great point, I thought it was a riot. Hope
you do to.
Matt Dralle
List Admin.
From: Al Mojzisik <prober(at)iwaynet.net>
Subject: RV-List: FAA BANS RV-LIST
FAA administrator, Jane Garvey, announced today in Washington that the
RV-List operated by Matt Dralle (On the left coast!) was to be shut down.
Citing the 51% rule as the reason for the shut down Garvey explained that
with the advent of Vans Quick Build Kits the RV-List offered so much
additional assistance to the builders that they no longer met the 51%
criteria! "These builders are really pushing the envelope!" Garvey was
quoted as saying. "They get all there builder questions answered by one
simple E-Mail to this list! They no longer have to spend hours trying to
figure out the plans and the manuals supplied by the kit builder. This
significantly reduces build time and they make far fewer mistakes. It has
taken most of the fun out of being the Administrator and besides, that
Dralle guy has nicer hair than me!" She also noted. Rumor has it that
Vans also supports the ban because they have noticed that the their sales
of replacement parts has significantly decreased since people get advice on
how to do it the right way the first time from "one quick question" to the
List. We were not able to confirm this rumor however.
It was suggested by Moe Colontino that builders supply their serial numbers
to the list administrator and if they cross check to a Quick Build serial
number then they would not be allowed on the list. Moe also asked that if
anyone had a spare empennage and NON-Quickbuild serial number he would be
interested in purchasing it.
Doug Rozendaal asked the administrator if it wasn't possible that she was
just jealous because Matt Dralle calls himself an administrator too? (The
List Administrator) To which Garvey replied, "Absolutely not! I can care
less what he calls himself! Don't you fly that pink airplane I saw at
Oshkosh? We'll have to have a closer look at that machine!" After which
Rozendaal withdrew his question.
Chet Razer and some others at this point in the meeting asked Ms. Garvey if
there was any more beer since they were done flying for the day anyway. To
which Ms. Garvey responded that that "was an inappropriate question at
such a meeting! " After which Ms. Garvey was bombarded with questions
about bolt torque, Extra storage space in RV's, numerous engine questions,
and finally some misguided newbie asked her about PRIMER!
After tearing her hair out (no wonder Matt's looks better) Ms. Garvey
suggested that maybe she better have another look at the RV-List ban and
reassess her position. She said she is open to more public input if you
don't mention PRIMER!

Hey John, Guess what? The day you pointed out that the hinges on the
Ferguson was worn and to me at the time they did look worn, I preceded to
disassemble the whole tail section. What I found would have amazed you and
the rest of the Kolb gang. I have witnesses that will attest to it.
Would you like to know? Well, I won't knock Kolbs because they're really
good airplanes and I like flying them and I would recomend them to anyone
who want a strong well behaved airplane not to mention I flew a MK3 for some
285 hours. My Mama always told me if I couldn't say anything good about
someone ( I believe that goes for most planes) to not say anything at all.
NO WEAR AT ALL ON ANY OF THE HINGES ANYWHERE ON THE FERGUSON. I might add
that I run the brace wires fairly tight. Even the bolts at the bell crank
pivots were like new. Come by anytime and I'll be glad to show you. The
spacing you saw in between the hinges was in both directions which was there
at initial installation. The hinges are of a double "X" configuration and
seem to be very strong in all directions. I did try to find some wear but
did not succeed. I also keep them lubricated with a light oil which probably
had a lot to do with the lack of wear. You're right in that they did look
worn but if they are I can't find it. There is no side play and no up and
down play.The Ferguson is by no means a perfect airplane but it satisfies me
and I'm the only one that counts. If I ever get 1200 hours on the Ferguson
it will be a long time from now. It will probably be retired a lot sooner
than that which means the hinges want have a chance to wear out.
Lets get back to Kolbs. My friend Jim is looking into buying a Kolb from
another friend of mine (Flint Burns AKA Canary). I talked him out of buying
a Rans not that the Rans isn't a good plane but it want fold like a Kolb.
Then there's the time involved in building while the rest of us is flying.
It is the Firestar, the one I flew to Sun-n-Money three years ago when we
all had such a good time around your camper.It can stay close to home where
the previous owner can stroke it once and a while. We're working on a new
private runway community north of P.C. where we will all have a place to
take the planes in case of another storm like Opal. 100' of my hanger was
blown away in that one. The new runway is in and I have the exclusive right
to have a training operation on the field so long as it originates from my
lot. I hope to retire there and fly 'til I can't see.
This is one sport that crosses a lot of years and friends tend to last a
long long time. I hope you will give me a call when you are down again and I
hope to take Bob up tomorrow if the wind isn't to strong.

Hey Richard, It's a 68'' quick ground adjust on a 3 to 1 E box behind a 582.
I did have some problems with the set up early on with the prop trying to
come apart at the hub. I always caught it in plenty of time though because I
use the inspection tape across the gaps between the blades that IVO
recommends. It took IVO three new sets of blades before we worked the
problems out . He would have given me my money back but I wanted to solve
the problem. There were others who had the same set up and the same
problems I was having. I've had three of the cams at different times on the
end of the torque rods break. THAT WILL WAKE YOU UP especially if your a
long way from home. That made it virbrates really bad at high RPMs but at
cruise it wasn't that noticable. Anyway I welded a little tit on the cam end
and ground it to the right pitch to match the other blades. No vibration. I
have broken two of the backing plates, the thin ones that the adjustment
screw is threaded through. I asked IVO to send me one of the thick plates
like goes on the other side of the prop next to the gearbox. He did with a
thin one to hold the adjustment screw. I put the whole thing on with two
sets of inspection tape forward and aft across the gaps. I've never had
another problem except when I kill really big bugs. Never broke another
piece of tape except when I pulled the prop to do a 50 hour inspection. I
also torque the prop bolts to 215 inch lbs. and check them@ the recomended
intervals. So far the torque stays where it's suppose to and I am happy with
the IVO'S smoothness and quietness.

Have you ever rebuilt an engine before? Do you have the proper tools?
Are you willing to spend the money to buy the special tools and the shop
manual? Are you mechanically "handy"?
If you have never rebuilt an engine before, go to a motorcycle junk yard,
and buy an old rotary valve Kawasaki two stroke engine. Tell the guy you
just want it to practice on, it will not need to run after you finish. Get
the shop manual for it. You should be able to get both for under $50.
Completely dissasemble the engine AND transmission, and reassemble it.
If you felt comfortable doing that, and everything made sense, and seems
to have fit back together right, now YOU decide if you want to tackle your
582. Either way, it was good experience, and money well spent.
If you decide to rebuild the 582, get a GOOD set of snap ring pliers, the
magneto puller, the wrist pin bearing tool, and especially the little tool
that goes over the end of the rotary valve shaft. Get a good torque wrench.
Understand what the book is telling you to do before you do it. If in
doubt, ask someone you respect. Get a helper that is patient when it comes
time to slip the cylinders back over the pistons. If you can get a helper
that has rebuilt 2-strokes before (successfully!), you are ahead of the game.
Good luck.

I think what it means is the air stream is blowing fluel out of the air
filters. I have used small conical K&Ns thru out life of eng, minus a
couple experiments with 6 inch flat/round K&Ns. Flat filters really messed
with carb performance (primarily hesitation during hard acceleration).
Ram air screws up fuel mixture calibration with these Bing Carbs. The float
bowl chamber has two sources of static pressure: vent tube and one on the
inlet lip of the carb. The vacumn chamber reads these two static air
sources and throttle setting (intake vacumn) and positions the piston w/fuel
needle attached, in the correct position to deliver the correct amount of
fuel being demanded by the eng. Stray air pressure or vacumn to the two
static ports screws up the carbs mind and eng performance, at times.
Right now I live with the following: I connect the two float bowls with one
piece of tubing. Mid point of tubing I drilled thru both sides of the
tubing vertical as well as horizontal (gives me four 1/8 inch holes). Now
both carbs are reading the same static pressure at their float bowl vents.
This prevents one carb running at different mixture than the other. This
mod seems to work well, but not perfect.
Next I have to work on getting good static source to the inlet static ports.
Two ways I think I can do that:
One way is put the aircleaners in the fuselage out of the airstream, using
tubing and one or two air cleaners. Or maybe using tubing and a 90 degree
bend to turn the aircleaner perpendicular to the airstream.
The other way (and not my idea) I saw in a picture of a trike powered by
912. They had fabricated hoods, same shape as conical K&Ns and a little
larger to place over the filters with maybe a 1/2 inch gap all around.
These could be metal or fiberglass.
I think either way would work. The latter, with hoods, probably be the
simplest.

Don't think there is enough space to reverse intake manifolds. That was one
of my original thoughts.
Carb problems on pusher 912 are not overwhelming, just annoying, especially
when one invests that much money into an engine. Last year I bought a
brandnew 351W Ford eng for $2,000. I could buy five 351Ws for same price as
one 912. hehehe

Hi all-
I have been dipping the rivits in Rustolium to prevent calvanic corrosion -
don't know if its necessary but I feel better. Anyway I have found that it
holds the rivets from spinning when I have to drill the occational...okey,
maybe numorous rivets out that I've goofed up. (I wouldn't dip them just for
that reason, its messy and slows you down)

(If the rivet wants to spin, make a little tool with
a flat sharp edge, ground out a little to stick under the edge of the rivet
head. This will put the brakes on the spinning rivet and allow you to drill
carefully).
I need to replace elevator and rudder hinges, but procrastinate for the very
fact that I hate to get started drilling a zillion rivets. Oh well, one of
these days.

Stephen, on pain of my being wrong as usual, here's what Dennis told me
when I went to Phoenixville to see and buy a FireFly. I asked why the FF
had TWO lift struts, when the other, heavier Kolbs had only one. Answer:
to give FF more drag to keep it under 63 mph. I have never heard of a
Kolb wing twisting in the wind. I realize others may say I'm wrong, so
ask Dennis. GB

Good Morning Steph..... and Gang:
Single strut bracing on the wing allows for wing twist and
failure.....................
If the above were true, there would be a lot of Kolbs out there with failed
wings. To start with, we'll get this out of the way quick, Firefly has two
lift struts per wing section. I assume you are talking about lift struts
although you say "single strut bracing."
Wing twist was a way of life with the Ultrastar, but I know of no Ultrastar
that had a wing failure because of wing twist. Of course I don't know much,
but I have never heard of such.
Firestar didn't have wing twist because Homer Kolb and Dennis Souder and the
rest of the gang at Kolb Aircraft came up with a much improved mainspar
attach system to the inboard rib.
Likewise, the remainder of the Kolb line. I invite you to try and twist the
wing of my old MK III.
Don't worry. The folks on this list that fly Kolbs are not alarmed by what
you say. We have a lot of combined experience in the air in all kinds of
weather, wind, loads, etc.
How this helps you out with your research.

Hmmm, I'm sure you'll get a few answers on this one. :)
The question about single lift strut is probably the biggest single false
rumor I hear about the Kolb from the unknowing. *It is obviously a fair
and reasonable question*, but any rumors about this being a weak point
in the design are simply from the unknowing or the envious. If you
build a Kolb, you easily see the aspects of the internal wing structure
that bear wing twist loads. It is clever, light, and very very strong.
I only know of one properly built Kolb wing that has ever failed, this
one from John Hauck, who was treating the plane more like a Pitts Special.
I'm sure he'll chip in here; it was a high time original (5 rib) Firestar
always flown extraordinarily hard (any and all aerobatics), and failed
just after a hammerhead or something similar. Kolb is the *only*
manufacturer who has flight tested one of their planes to the point of
structural failure. It failed far beyond stated load limits, was not
a wing twist failure, and was even improved upon from that test.
Here's an example of the typical rumor on this. A guy I used to fly
with scoffed at my single lift strut Kolb. In typical "Unknowing"
fashion, this person drilled (4) 3/16" rivet holes 1/3 the way up on
points for a 2 gal gas can on each strut!!! What a fool. He assumes
the Kolb lift strut is inadequate, but he drills holes and adds a large
mass (the filled gas cans) to the middle of a key structural part of
his Challenger. I still can't believe it! (I think he decided to go

Hi Guys:
A previous note on this list indicated that I had a wing failure on my old
original 5 rib Firestar. That is absolutely true, but the cause was not
from wing twist. It was from 755.0 hours of extremely hard flying, 1000's
of aerobatics combined with many long XCs flying overloaded in all kinds of
winds and weather. I flew this old Firestar like there was no red lines
anywhere. We were always wayyyyyyyy out of the flight envelope and
eventually just wore the little airplane out. This was the 1988 Sun and Fun
Grand Champion Ultralight and the 1989 Oshkosh Grand Champion Ultralight.
This airplane flew in 32 different states and Canada, just me and airplane.
I learned from this experience, that nearly cost me my life, that stress is
a cumulative thing. My little airplane started out life with a whole
number: 1.0. Everytime I stressed her I was subtracting a little from that
whole number. Eventually I asked her to do something and she told me very
abruptly, "Sorry, can't do it!!!"
Live and learn almost turned into die and learn. Thanks Jim Handbury for a
reliable hand deployed parachute.

Not that I know of. I have a pretty good handle on the database of Kolb
accidents. Structural failure is not on the scope. Crow hopping accidents,
engine seizures, first flight/ inexperience related accidents, there are alot
of these. There is one "structural failure" but this one is cannot be fairly
chaulked up to the Kolb company because the builder failed to install a major
structural bolt. If you are going to fly a Kolb it is much more likely that
the engine will let you down, not the airframe.

and this list would not exist. The only Kolb wing failure that I have even heard
about was a compression strut failure on the earliest design of the Ultrastar.
The only shortcoming that I can think of is that if you wreak a Kolb, it's
probably going to be expensive to repair.

Hi Gang:
No mods to the Firestar. Strictly stock except for the longer 4130 heat
treated gear legs.
Please do not take your hat off to a fool who had no idea I could not get
away with flying an airplane to that degree that was not designed for that
type flight. My last aerobatic maneuver was 11 Mar 1990. Made a normal
takeoff but landed under a canopy, much to my surprise.

I should change this thread subject line to "Loose Lips ...MINE".
On my post about this earlier today, I made reference to John's FS wing
failure. He had related that to me as part of a private (him and me)
email exchange several months ago, and it was our understanding that it
was private info, certainly not mine to make public.
So today I screwed up badly. While writing earlier today, I had myself
thinking I was repeating a piece of that exchange that was perhaps
known history. But I started to realize my mistake more and more as the
seconds passed after hitting the Send key. I blew it and my sincerest
apologies go to John.
There is no way I can undo that send. I just wanted you all on
the list to know that I've sucked John into a discussion that might
better be left dropped. Worst of all, I slipped and breached a mutual
understanding. As a matter of list-serv habits, I realize even more
now how oh-so-important it is to review what you say, names you mention,
etc, etc.
A key piece to the original subject is that these planes are solid but not
designed for aerobatics. Kolb says don't do them. John didn't want to
talk about it. I'm wishing like heck the subject would die, and after
this message I think I won't hit Send on anything for awhile.

Hey Guys:
I reckon I better comment on John J's very broad statement on expense
involved in repairing Kolbs. I find that most of the repairs that are
required in normal everyday little crashes, scrapes, rips, and tears, a few
bent aluminum tubes, and cracked nose pods, etc., can be fixed with what ya
got left over from building, unless it has been a long time since you did
your building, but by then you know how to do most of it cheap.
Big jobs like rebuilding fuselage, building new wings, or your butt, can get
right in yo pocket book. Neat thing about these little planes is that most
of the repair work we can do ourselves cause we built these little suckers.
For us that have our planes registered EXP, we get the FAA Repairmans
Certificate for our particular airplane and can sign off on all our repairs.
Don't have to hunt down and a&p to do it for us.
Nuff said on that,
john h (going to wash off the dirt and leaves I been playing in all day)

Steph and all,
I would say the person who told you that was incorrect. I think the Kolb
wing is very strong. I just helped a friend cover his today. It uses a 6"
main tubular alum spar, built up ribs and drag strut, steel inner rib and
attach points and Stits cover that prevents any twist. A single lift strut
is very adequate. The streamlined formed lift strut when lined on the
inside with a second tube can function without even the jury strut. The
only reason that Kolb uses double struts on the Firefly (I was told by a
person within the company) is to add more drag to fit within the Part 103
speed requirements. I have the MKIII (jury strut free) and am very happy.

Hi all-
I hope I'm not upsetting anyone, especially you Ben, by responding to this
thread yet one more time, however one of the most valuable contributions
this list makes to me as a Kolb pilot wanna-be is the open and honest
sharing of mistakes those of you with much experience have made. By the way,
I'm building my Mk III up in a loft at my in-laws place of business. Two
gentleman have come up to check it out. Both are GA pilots and both have
immediately commented on the impressive construction of the wings.

I too had an "early edition" UltraStar that lacked the inboard ring around the
end
of the tube/spar. I added a ring using chromoly flat bar & plate. Form the flat
bar into a ring of 2 halves with the 4ends bent out 90* & drilled (so the 2 halves
can be bolted down on the tube.) On each half, I welded 2 tabs, spread equally
apart on the edge of the ring. The face of these tabs are perpendicular to the
spar & parallel to the edge of ring. This is then bolted & rivoted onto end of
spar. then out of the flat plate I cut out an X that connected the 4 tabs &
rivoted it to the 4 tabs. All the rivot & bolt holes should be drilled before
welding the tabs as the metal will be difficult to drill afterwards. All this
can
be done with just a 16" hole cut out of the inboard side of the wing. The
difference in handling was astounding. It was crisper & rolled much faster. It

Stephen,
I have the 5-rib wing of the Original FireStar and my buddy that I fly
with every weekend has the same. He bought a used one and after taking
the fabric off, noticed extra drilled holes on the bottom of the main
spar, at the H-section, because the builder botched the repair job after
an accident. He has checked it over thoroughly, the A/P mechanic that he
is, and determined the plane is safe to fly. That FireStar I'm sure has
over 400 hrs logged in 12 years with the 447
40 hp engine. He does inspect the spar on a regular basis and sees no
problem. My FireStar has 420 hours on it and we both are flying out to
AirVenture '99 next summer. If there was a problem with our older
FireStars making a trip like that, we definitely would not be doing it.
You can expect to see two Original FireStars out there, one with extra
holes drilled in a place you wouldn't want them, but then that hefty 5"
spar has proven itself on other Kolbs in many compromising situations.
Back in my early days when I was learning to fly the thing and I'd have
it in a 90 mph dive by not paying close attention to my airspeed and if
there was a wing twist problem, I wouldn't be here telling you this. By
the way, we both fly without parachutes. I say this not because we are
stupid pilots, but because we believe in what we fly is more than
adequate to get us there and back again ....... safely.
Any more questions?

Gosh John I am afraid the only way to get Ben back for this breach of

Anyhow since Ben (the mouth) Ransom ;) brought it up what actually happened

I would have thought the opposite. Most of the tubes you can buy at a
metal tube store. Most of the steel can be rewelded. If you wreck a
Challenger or
Quicksilver then you will be paying big bucks. If we can build it we can fix it.

Hi Stephen: Can't resist getting my .02 worth in too. I mentioned some
time ago to the group that I had to make a choice while building my Mk III.
I had enuf money for full radios ( for flying in LA airspace), or a
ballistic chute - not both. Chewed my nails some till I built the first
wing. Hah ! ! ! Sent the money for the radios. Maybe get the chute
later, but I doubt it. If you'd like some numbers, consider this: The
main spar is 6" dia. and measures a little over .090 wall. There is a
massive steel rib / ring solidly rivetted to the inboard end. 9 more ribs
are rivetted on with 10 steel rivets each. An additional 18 half ribs are
spaced between the 9 full ribs, and rivetted to the spar and to the leading
edge. Full ribs are rivetted to leading and trailing edge spars. That's
for each wing. Drag struts are 4 - (four) - thicknesses of thick aluminum
tubing, telescoped and steel braced. One of my pilot / builder buddies
said "My gosh, you could hang a 172 from those, and they wouldn't even
creak." Nuff sed. Just something to get the group going
- maybe a little twist - built in - wouldn't be that evil a thing. A
little washout might make it almost unstallable, cause the tips would keep
flying after the inboard sections were stalled. Course, I understand
Kolb's are very mild in the stall anyway. And, thinking about it, you'd
probably lose some lift. Any of you engineer types have any thoughts ??

During my ongoing search for ways to reduce my EGT's I found that the factory-
set timing was 2.2 degrees late. Rut Fuller confirmed this observation and
worked with me to insure dead-on resetting. Tom Hertz, our resident factory-
trained expert, was not so sure we should have reset the factory's timing
because he thought they set it electronically at during the factory test run
and it was optimized for this particular engine. He reasoned that the
standard .086-before-TDC / eyeball-to-reposition-the -transducer method was a
field fix and probably not as accurate. My argument is that even if they use
a timing light, access for repositioning (tweaking) the pick-up transducer
would be a major problem. Yes, the EGTs did apprear to go down slightly after
we reset by the "field" method.
Here's another thought on EGT probe/gage systems. Are Tempilstick temperature
indicators accurate enough to use in varifying calibration ? For folks who
don't know Templesticks look and work like color crayons but the marks they
make melt at a given temp. It would seem that we could put a Templstick mark
on the probe and watch the gage as we apply heat with a heat gun. I bought
two of them at a local welding supply ( $8 a pop) but they did not know much
about them. I remember that we used them in liquid rocket engine test firings
but that was long ago. I am planing to cal the Mfgr today and will report

I wouldn't put any in. As we discussed a few months back, the planes
fly/mush along at stall speed without spinning, even with mild aileron
action. Although not advised as normal practice, they can even be aileron
controlled (roll) while stalling straight ahead. That's pretty stable
stall mode flight and I wouldn't fix what ain't broke.

Hi O.P.: Not a bad plan. Can you notice any effect, beneficial or
otherwise ?? I learned about the benefits of WO in flying school. Now I'm
learning that hang gliders have quite a bit of WO, and on my last lesson I
repeatedly found that the stalls were unbelievably mild - even in a turn,
and even in a quite steep turn. Believe me, I was really watching. That
was Momma Bourne's young son hanging up there, and I may be loco, but I'm
most certainly not suicidal, local opinion to the contrary. Big

Hi Group: A week or two ago, there was some discussion about tightening
fabric on wings, and some of the problems that crop up. Last night I was
re-reading the Oct. ' 98 issue of Sport Aviation, and toward the bottom of
the center column on page 93 is a reference to inter-rib bracing tape. On
page 94 is a diagram. Since I'm getting quite close to covering - finally
- I listened to you guys, and then read this with great interest. Any
commments ?? Seems like this could really help the " wavy ribs " problem,
with almost no weight. Or is it that much of a problem. The point was made
about the last half-rib, between the last rib and the wing tip as being
difficult to hold straight under fabric pressure. Would this hold it
straight and true ?? TIA. Big Lar.

Hello Jerry,
I have over 300 hours in a Flyer. Also have some images of it on my
webpage:
http://www.angelfire.com/ok/froghair/
Overall, it's a great little plane although it does come-up short on
climb-out (~200 fpm max). Aside from that, it handles like a dream, very
forgiving but able to handle a pretty stiff wind also. Mine has Solo engines
and they require a little more attention than a Rotax but the parts are
quite a bit cheaper.
If you want to know specifics, ask away...

<< A little washout might make it almost
unstallable, cause the tips would keep flying after the inboard sections
were stalled. Course, I understand Kolb's are very mild in the stall
anyway. And, thinking about it, you'd probably lose some lift. Any of you
engineer types have any thoughts ??

I love my Firestar, don't get me wrong, but I think that it could be brought
closer to perfection here on earth, If it had wash-out. It would add drag,
sure, but it would do just as Lar says, keep the tips flyin when the main wing
stalls. Maybe the drag could be compensated for by changing the angle of
attack of the horizontal stabilizer to a more flatter angle instead of the
LARGE angle presently built in....this also causes drag!.....plus stability of
course, , but isn't it nice not to have a wing tip drop off heading for a
spin.. The pterodactyl had that washout, and I considered it one of the
safest to fly because of it................very docile in spite of having a
short chord.......GeoR38

Hi Gang:
Been a while since I did any covering, but I doubt if it has changed since I
last covered my MK III wings in '92or '93.
I was self taught how to cover, dope, and paint fabric covered airplanes.
Started in '84 and did a lot of it until the final cover on the MK III. Out
of three airplanes I built and finished, two of those planes got the wings
covered twice, the MK III had two sets of wings the first few hours of
flight. All turned out pretty good. What I learned about covering and
painting I got out of the bible "The Stits Manual" and the covering and
painting instructions that came with each particular plane kit. I found if
I did what Ray Stitts told me to do I would get good results. I did and it
worked.
I shrink the fabric tight, cause in the winter the fabric will loosen up
some when it gets cold, and I do not want loose fabric. I shrink the fabric
on the wing before popping fabric rivets. Once the fabric is tight, if a
rib has a little curve to it, I can straighten it up thru the fabric. Once
it is riveted, I lose that option. Outboard false rib won't go anywhere if
it is properly braced before covering and shrinking. It is awfully
rewarding to do a good covering job and a lot of fun. Enjoy it while you
are learning and when you are doing it, cause when you finish, that part is
all over. Don't personally recommend rivets before or during the fabric
shrinking process.
Gotta go look at the Atlanta and New Orleans sectionals, maybe Jacksonville
too, and get ready to go to the BBQ Flyin at Quincy, Fl, Saturday. Gosh, I
haven't been anywhere since OSH.
Later Gang,
john h

Last weekend I bought a 1/2 ownership in a project. An old man in our area

Here's the interesting part: with only cosmetic changes, and a slightly
longer landing gear, he has built it into a scale replica of Roscoe
Turner's "Turner Special", a racing plane from the 1930's.
Unfortunately, after his death, his daughter threw away a lot of his

Hi Richard and Gang:
Sounds like Richard's MK III non-standard wing has the same flight
characteristics as all the Kolbs I have flown. The Ultrasater, Firestar,
and MK III all use the same wing section outside dimensions except span.
All fly just like Homer Kolb wanted them to fly, gentle with no surprises or
bad habits. The Slingshot also shares those wonderful Homer Kolb flight
characteristics.
Thanks Homer,

As promised, please find attached a list of everyone that has made a
contribution as of Thursday 11/19/98 in the Fall 1998 List Fund Raiser!
If you made a contribution using a company check, be sure to check under
that company name if you can't find your personal name. To the best of my
knowledge, there is only one name that is missing and that was a cash
donation in which I misplaced the envelope. If you sent cash, and your
name is missing, drop me an email and I'll make sure that your name is
listed on the follow up Contributor List post in a couple of weeks.
Well, I must say that this was the most successful Fund Raiser for the Lists
to date. I want to thank each and every one you that has made a contribution
to support this valuable service. Your generosity has paid for the most recent
system upgrades and will support the on going expenses of running the Lists
into the coming year. The number of contributing members as a percentage of
the total number of members on the combined lists was up by 100% percent this
time. There were many 'first time contributors' this time around, and I want
to thank them for coming on board!
I also want to send a personal and hearty thank you out to my good friend
Al Mojzisik for his unrelenting support, encouragement, and creativity on
my behalf during this Fall's Fund Raiser. Al, you're a great friend and
I thoroughly appreciate all of your help. Thank you!
I would also like to thank those of you that posted inspiring words about
the List and what it means to you. It would seem that your comments inspired
many to make that first time contribution!
Many of you included a few words of thanks and encouragement along with
your contributions and I appreciated each and every one. I was very moved
by the incredible support and friendship each of you have expressed. I have
been very inspired by your kind words and appreciation of the long hours
I have spent maintaining and upgrading this service.
If you were meaning to make a contribution but it slipped your mind, there is
still plenty of time to get it in before the next Contributor List posting.
As I mentioned above, I will be posting a Follow Up Contributor List in
about two weeks to acknowledge the stragglers.
Thanks again to *everyone* that made a contribution! *YOU* make this List
possible! I'm just here to steer... :-)

Hi Duncan and Kolb Gang:
I have used a hand deployed prcht twice, both times forgot to kill eng.
First time was still at full throttle when chute deployed, second time was
at idle when deployed. Both times the eng was still idling when we hit the
ground (me and the plane).
I think I recall a prop fouling a chute. It'll wrap right up in a second.
My Brother Jim made me a kill system for my 582 from a Radio Shack Plastic
Box and two sets of Ford ign pts. Took some 1/16 lexan hooked to a 1/16
inch cable which was hooked to the bridal loop at the apex of the canopy.
The lexan went into the pts which were spliced into a wire from ground to
kill wires. When prcht fired, cable pulled lexan out of pts and killed eng.
Believe me, unless you are some kind of super cool dude, you won't be
thinking of hitting kill switches or anything else except getting your buns
safely on the ground.
When I replaced the 582 with the 912 I didn't reinstall the kill box because
it added to the complexity of removing the center section. Do I really need
it? I don't know. It is debatable, but for now I fly without it.

| Subject: | Floats and gross weight |
Hi,
I'm interested in putting my FireFly on floats; maybe a Full Lotus
monofloat. It seems like a Full Lotus Monofloat 1000 would be
sufficient, but the FBO at a local airport has a few used and new
1700 and 2000 Full Lotus monofloats which he just aquired and is
interested in selling (he doesn't know what he wants for them yet
though); would something like that be overkill for the FireFly?
If I do this, it would definitely have to be an amphib setup; I don't
want to be stuck with land or water, I want to use both... According
to Full Lotus' web page, the 1000 and 2000 can be set up for amphib
(pricey!!!!! $$$$$$) :-( but the 1700 can not. (Any less costly
options here?)
My main question though is... I'm already at gross weight for
my FireFly. Actually, I'm slightly over, maybe 520-530lbs and
I believe the gross weight for the FF is 500lbs. Does adding
floats affect the gross weight? Obviously they'd add weight,
but I thought maybe they act as a "lifting body" which
would offset it... ?
Oops, I thought of another question: How does the monofloat
attach to the plane? Is there a mounting kit or something that
I need to buy from someone? (Kolb?) If so, anyone know
what it costs?
Ummm, one more question. :-) If I were to get my FireFly on
floats, I've played with the idea of registering it as an experimental
so that I could build float time (for reduced insurance premiums, etc).
Is there any problem with using Full Lotus floats on an Exp. aircraft?
Any "gotchas" to look out for here with registering my FF as an Exp
floatplane in general? (I am the 2nd owner, and not the original builder.)
Any info or advice on any of the above would be greatly apprecated.
Thanks!
-Jon-

Yes, there have been cases where the pilot didn't not turn off the engine
before deploying the chute. My own experience:
upon inspection of a 2 seater Q/S before I took my first lesson; my friend
(experienced pilot, came along to see if I'd puke after the big breakfest he
gave me) found on the BFI's plane that the static strap that holds the chute
to the frame would have fouled because of the way it was tie-strapped on the
vehicle!
IMHO ::: Ignition breaker would be nice, but I can for-see the problem will
be the propeller windmilling for a few seconds or so...it would have to
have a delay of some sort so that prop stops before deployment of the
chute...

| Subject: | Re: Floats and gross weight |
Jon,
I've thought a lot about adding floats too. I haven't decided yet,
but I do know that I wouldn't add them unless I could do it for under
80-100 lbs. Even that much added weight is a significant compromise to
what used to be a 300 lbs empty weight plane. The other big piece of it
is that even without floats, you can land in a ton of places right next
to the water. I know that ain't the same, but that and the fact that
tundra tires and good gear allows much rougher, shorter landing spots
in a variety of places is a valid argument against floats. Then there
is the compromised flying attributes of the plane and the added risk
of water operations. All that said, I'd still love to have some super
light floats and may build them someday.
As for the gross weight thing, I'd assume that the float is not a
lifting surface, rather, just added empty weight.
One thing about registering Exp, I assume then that you would need
to get a Seaplane rating. Cost, choke, glug, ...

I have an engine shut down switch built into my Chute deployment handle
mounting. It is out of reach so it won't be accidentally be actuated but it
is physically tied to the actuating handle. If the engine is running WOT and
the cable gets hung in the prop at least the prop won't have a full power
stroke behind it. The BRS reps at Sun-n-Fun liked it but said it was more
important to make sure that the rocket, cable and canopy have a clear exit
path. Mine is a built in soft pack which means I have to have a door or
burst-open hole for exit. I am satisfied that between my carefully designed
exit, automatic shut down switch and IVO prop which I think would quickly
shear off if it met the cable I'll have a pretty good chance if I ever had to
pull that handle. I'm not sure one of those nine pound Warp props would shear
as easily.

I've seen several planes with this setup, as a backup. I plan to implement
it in my Challenger currently under construction. It's definitely not as
good as having a delay to let the prop fully stop, but it is better than
deploying the chute into a prop spinning at 2000 rpm.

Nope! not necessay. You don;t need a seaplane rating to legally fly a
experimental plan (or a tail-dragger endoresement, or a mult-engine rating -
if your exp. plane falls into these).
You will need it to get insurance though. :)

Hi Guys:
Do you all really think instantaneous deployment is not as good as having a
delay? Not hardly. I can almost guarantee you won't want to be sitting
there fat, dumb and happy, waiting for your prop to stop so your chute will
deploy. Uh, uh!!!!!!!!!!!!
If and when you get in a situation when use of the chute is necessary, it
won't be like on a nice Sunday afternoon flight where you have time to
decide what to do and nonchalantly do it. Your altitude at the time is a
big determining factor, attitude of the acft, is it stable, spinning,
flipping, flopping, what ever. It will be a big shock that demands instant
action, right now.
My first deployment was at 200 feet and 75 mph. Airspeed saved my buns.
Second deployment was aprx 500 feet. Not a split second to try and decide
what you are going to do, when the acft is in a 90 degree dive screaming out
of the sky.
I few days before I used my prcht the first time I was in Florida at my
brother Jim's house. We we were going to repack the chute. Jim asked me if
I had ever practiced throwing the deployment bag. NO! He sat me down on an
airconditioner unit with my prcht on and said: "Deploy it!" I did.
Several days later I did it again from the seat of my Ultrastar at 200 feet
AGL. I also practiced in my mind over and over what I would do if I had the
requirement. It was second nature, automatic. Same, Same in the Firestar.
I practice reaching for the deployment handle on the ballistic chute in my
MK III. I know where it is and I can get it with either hand or both
without looking for it. In a wildly spinning tumbling acft it may be more
difficult locating and pulling that red handle. Make it second nature to be
able to do it without thinking about how you are going to do it. And don't
fly with the safety pin engaged.
I remember a gentleman at Sun and Fun 1990 who saw a video of my prcht
deployment in the Firestar. He said he thought he would put his prcht back
in his airplane after he viewed the tape. He had flown with it for 6 months
and didn't need it, so rather than carry the extra weight around he took it
out. To me the prcht is insurance. I don't know if I'll ever need one
again, but if I do and I don't have it, it won't do me any good. I've
carried the 21 or 22 lbs of prcht with me since day one in the MK III.
Never flown the airplane without it. It is a permanent part of the
airplane. I don't realize the extra weight; to me it is not extra.
Just a little food for thought,
john h (getting anxious to fly to Florida in the morning)

Hi Gang
I also fly with a BRS on my FSII. I think an old ad said it best.
And I
quote, " I was once asked if I ever used my parachute. I replyed yes, I use
it every time I fly, but I have never had to deploy it. Food for thought!

Ray,
I cut one of mine down by 1/4 length and then cut a slot (about 1/4 of the
circumference) out, then I screwed it to the wall and kept all my tubes in
it. The cut length allowed the uncut tubes to hang out so I could see what
was in there (it was mounted on top of a shelf above eye level, but out of
the way) The small piece I just screwed to the wall and put any small cut
pieces in so I could see and use them possibly later.
Hope this helps.

Guys,
A rectangular wing will stall in the center area first and this is why
you will hear the "burble" in the prop prior to stall. There is no need
to add any WO with this type of wing. I'm sure this is exactly why Homer
used this design.

I had to cut the shipping tubes with a saw to pieces less than three feet
befor the recycling center would accept them as cardboard.
Be careful though as this operation claimed first blood on my project.

Would you be willing to share/loan a copy of this tape for the benefit of us

(I would be happy to pay for handling/shipping costs or provide duplication

Hello everyone,
Richard came and took the SS away yesterday, so it's time to move on. I'd like
to thank everyone on the list for all the advice and entertainment I've received
over the last couple years. Even though the SS didn't turn out to be exactly
what I wanted, I don't consider the time and money to have been wasted.
Overall, it was an enjoyable experience, and along the way, I met some great
people, and made some lasting friends.
Later today, I'll be leaving the list, and also removing the SS pictures from my
web site. Will Uribe has volunteered (didn't say no fast enough ) to post
some of my pictures as long as there's any interest. I sent him a CD-ROM last

Take care, and I'll see you in the sky when the RV-8 is done.

Russ,
We're going to miss you. It was good visiting with you over dinner (thanks
again) when you passed through Dallas. I hope the progress on your RV goes
quickly and you are into the air quickly.
I flew today for the first time in about 3 months. I couldn't believe it
had been that long, but my logbook reminded me. I have little excuse
except the building of our house in Central Texas. It only took me one
landing to feel comfortable again. I raised the clip on the needles of my
carbs one notch and they are preforming perfectly as regards the EGTS...
right around 1100 instead of below 1000. All the other gauges are in the
optimum range. I noticed that flat out straight and level my rpms were
climbing above 6500. I may tweak in a little more pitch on the AQ-IVO.
I bought a used ICOM headset adaptor for my ICOM A21 and it works very
well. I never could get the intercom (cheap one) that I bought to work
properly. Now I will be able to announce my intensions instead of just
listen to others. I feel a lot safer now. The traffic at our airport
today was busy with usually two or more in the pattern.
Pretty soon I will switch over to the full doors and full enclosure as the
temps are beginning to turn cooler. Today was cloudless with a 10 mph wind
aligned with the runway and mild temps. Perfect.

Well, that was clear as mud. Let me try again.
The waiver (think I saw it mentioned on this list) is signed by me, the
grateful UL owner and given to the property owner and it says something to
the effect that I waive all rights to sue him/her for any reason while
performing my UL activities on (or from) their property.

I have made several fiberglass fairings /gap seals on my FS2 covering a second
chance softback. I used laminated balsa for an exit area as long as the pack
opening and about 3/4 width. Make sure that the areas surrounding this exit
hole are smooth and snag free. It would be a real letdown to have a

David,
I'm at a loss to help with your reference but it sounds like you know
what you want the 'waiver' to say - so why don't you just write it?
Actually the above couple sentences would probably do.
I had to sign a "waiver" to rent my hangar. Upon seeing it, I asked the
landlord where she got it. She said she had paid a lawyer a couple
hundred bucks to write it up. I compared my copy to a standard lease
agreement available for about 50 from any office supply store -
virtually identical! The lawyer skinned her for a couple c-notes by
taking a standard lease and replacing the word, "contents" with
"aircraft."
I didn't have the heart to tell her I was flying a "vehicle," not an
"aircraft!"

Dear Listers,
After a full weekend's work, I've come up with a really nice new List
Subscription web page. The page allows you to Subscribe, Unsubscribe,
and Search for your email address on any of the Email Lists. Subscribes
will still require Administrator Approval, but the page should really
go a long way to making the overall process much smoother for everyone.
The standard Majordomo email method is still available, but I strongly
recommend to everyone that they use the web page excluseivly.
I have also made some rather extensive modifications to the text trailer
appended to each of the messages posted to the List. I've added a number
of web site URLs that should answer many of the questions I seem to get
daily. I know the trailer is a little on the long side, but its great
reminder for everyone, and I filter it out before appending messages to
the Archive.
Please have a look at the new List Subscription Form and maybe see if
you can locate your address using the search capability. The URL for the
new Subscription Form is:
http://www.matronics.com/subscribe
There are a few other permutations of the "subscribe" portion or the URL
that will work as well, for example "unsubscribe", "subscription", etc.
But these all take you to the same page, so just remember the URL shown
above.
Enjoy,

Woody, Ray, et al.
Am still alive and more or less, in operation... Thanks for asking... Sent
Ray a separate note a little earlier when I came across another one from
him... I am methodically working my way through the half-million or so
e-mails which have accumulated while I was out foolin around at the office
for the last month or so... 'Ol Saddam has us in high gear at work, and I
haven't had much chance to even do the eat - sleep - change drawers routine
to acceptable standards, much less fool around with the pile of dacron and
aluminum refuse heaped in the garage... (good thing I still wear O.D.
drawers...)
In late October, I finally got some fabric on the horizontal tail surfaces
and the rudder... This modest progress was compromised, however, by the fact
that my current Bride insisted upon leaving the garage door cracked about a
foot, so that her worthless little fuzz-butt cat could go in and out... When
I finally managed to get out there to do some work this weekend, I learned
that the result of that particular intellectual shortfall has been the
apparent adoption of my garage as some sort of high-performance proving
ground for exotic feline waste distribution and advanced hydraulic
experimentation... and it was evident that at least a dozen or so of the
more advanced participants had some bizarre
affinity for anything with Ray Stits' name or logo on it.... Particularly
the Polyfiber already installed on the stacked-up tail parts... There also
seemed to have been a great deal of interest in settling the matter of
ownership of the large roll of dacron fabric still under the worktable...it
was "marked" virtually from end to end with such a thoroughness, and to such
a depth, that a reasonable person would have difficulty buying the notion
that this result could have possibly been the result of random actions by
uncomprehending dumb animals... In my mind's eye, I could just see the
little buggers lined up waiting their shot, each with a little number
clutched in his paw, while the furry little foreman directed each, in turn,
to the precise location called for in the master plan....
Long story short... The neighbors were treated to the sight of yours
truly, on his flabby belly and bony knees in the driveway scrubbing what
they probably thought was the longest piece of cheap white carpet they had
ever seen with soap and hot water... Most of the obvious stench has
abated... although I have now fully reconciled myself to the fact that no
machine bearing the distant but unmistakable essence of feline territorial
imperative is ever going to grace the big winner's circle at Oshkosh, I
guess I need to reassure the cat lovers on the list that no harm came to the
'ol Lady's little fop of a long-haired cat over this... I do admit,
however, that I went ahead and cleaned a couple of toilets with him while I
had him all lathered up from doing the dacron on the driveway... But I went
ahead and dried him off and put him out in the back yard... Did you know
those little suckers get about a yard across after 15 minutes on the
permanent press setting? He still won't come when I call, but he does stay
in the yard when I go outside with food, now....
I cannot see inside the tail pieces, and I absolutely refuse to peel off the
fabric and do them again... I washed them out as best I can. I reckon we
will now subject 'ol Ray's epoxy primer to a long-term test by a solvent
vastly more formidable than mere MEK.... Last night I dreamed I was
taxiing down a ramp at high speed, closely pursued by a huge pack of dogs...
(sigh...)
Pray for peace... these hours are killin' me...

Happy Monday Morning,
Had a good time this weekend. Flew down to Quincy, Florida, for their
get-to-gather.
Sat morning I got up at six, the OAT was 35F. Ugh!!! Too cold for an old
fart to go flying around the countryside without an ECU (environmental
control unit) or in our terms, a heater. By eight it had rapidly risen to
38F as I loaded Miss P'fer and got ready to fly. Took a little coaxing to
get the 912 to start and run, the enrichers weren't up to snuff for the cold
damp air. I bought a new Wal-Mart 14 amp battery last month and it did its
job. No need for a jump start. God blessed me with a good day and we were
off the ground at 0830, winging our way southeast. I had to stop after an
hour and check out the back of a hanger in Clayton, Al, then another hour
and I was landing at Quincy.
They had a good turnout for the flyin, Kolbs overwhelming all other brands
of ULs and Exps. Mike Highsmith and Richard Lovell from Panama City,
Florida, were there when I arrived. Both previous Kolb owners, both have
decided to fly "other" brands of acft.
The Quincy boys had the grills hot and smoking. I sampled some of the best
venison sausage I had ever eaten followed by a delicious cheeseburger.
Compliments of the Quincy gang. Got to see Ruts "original" Firestar, that
brought back some memories of the 80's, and Dwayne's Fire Fly. Both good
looking airplanes.
My Brother Jim met me at the airport and later took me to St Marks for a
delicious fried shrimp, oyster, and Grouper dinner. Thought I had died and
gone to heaven. Overslept Sunday morning and got back out to the airport
for a noon takeoff for Hauck's Holler. It was misting rain, and cool. The
airport was almost deserted. We poured 5 gal of 93 octane in Miss P'fer for
insurance, then gave a gentleman, who was flying a two place Quicksilver a
short demo flight in the MK III. Needless to say, after getting out of the
Quick, he was impressed with the MK III and is going right out and buy one.
hehehe I gave him a good flight and the 912 performed first class. With
two up and almost 20 gals of fuel, plus my gear in the gear locker, Miss
P'fer was climbing 1300 to 1500 fpm. She made me proud of her. However, I
think we were taking advantage of the nice east wind reflecting off some
rising terrain. I didn't tell him that. Did some steep approaches,
couldn't see his eyes, but I bet they were wide open when I initiated the
first one. I tapped the vsi with my finger, he didn't have a headset, to
show him it had pegged at 2500 fpm rate of descent and 65 mph. What a
performance. Couldn't haul her to a stop as quickly as I would have liked
to cause the800X6's had turned into skis on the wet grass.
Off Quincy and with a pit stop at Clayton, Al, again, was touching down at
Gantt International Airport in less than two hours. Not bad for an UL to
fly 176 miles. I still had over 10 gals fuel when I landed. I could have
made the flt down and back, with play flying at Quincy, and had a five gal
reserve, but why take a chance on wind, weather, or some other act of God or
Rotax or "Murphy."
Had a great time and look forward to the next.

<< I have almost finished my soft pack (leading edge) installation. I hate to
see my alum-lexan gap seal go in favor of fabric seal. I would like to
talk to those that have done something other than fabric. How did you
rocket or entire chute pack? >>
Bruce,
I have a Second Chantz soft pack mounted between the wings. The rocket motor,
which is about 1.5" in diameter, points straight up and sticks out about 3"
above the center section. The center section gap seal is made up of lexan,
with a piece of aluminum at the leading edge spar, as was explained in one of
Kolbs newsletters. I cut a round hole in the top lexan for the rocket motor
to protrude through. I then cut the top lexan to form a trap door, which is
about 6" wide and 12" long, big enough for the chute to be pulled through.
The trap door is made by cutting two slits 12 " long, fore and aft, about 6"
apart, and one slit going across at the aft end, connecting the two 12" slits.
The cross slit must intersect the center of the rocket hole, so that the cable
is free to pull out the chute, which would then force open the trap door. The
'hinge' of the trap door is simply the lexan 'bending' and is located at the
leading edge of the door. Once the door is cut into the lexan, you have to
secure it in the closed position, because the natural tendency is for it to
spring open, due to the curvature of the lexan gap seal. I just used some
tape to hold it closed. The rocket motor has plenty of force to overcome this
light restriction.
The lower part of the gap seal is harder to describe. On my Original
FireStar, there is a U shaped tubing (a hoop) above my head. First I pop
riveted a piece of aluminum sheet on top of that, on which I set the soft pack
chute. Then I cut out most of the lower part of the lexan gap seal, so the
cut out resembles the hoop in shape, but still leaves an edge resting onto the
edge of the hoop plate. It just doesn't cover the central part where the
chute is sitting. In other words, the bottom part of the lexan gap seal
covers the bottom surface of the wing, but only extends onto the hoop plate,
reaching in about 3/4" all the way around, for support. Now it gets even more
difficult to explain the rest of the job. I cut another piece of aluminum,
about 2" wide, in the shape of the hoop plate, with the outside edges even
with the previous mentioned hoop plate. Then I cut another piece of lexan,
about 1" wide to the same shape as the 2" aluminum, except it is 1" smaller on
the outside dimension. Both sort of resemble a horseshoe shape. These were
pop riveted together (sandwiched) onto the aluminum hoop plate. This made a
groove about 1" in width all the way around on the outside edge, for the lower
part of the gap seal to slide into and keep it from interferring with the
chute pack. This permits me to easily install and remove the gap seal, which
I have to do since I fold the wings after each flight. The gap seal is held
in place with velcro at several locations. Any questions?

CARBON. Too much of it. After removing the engine assy, I took it home to
disassemble it in my shop. I thought for sure it was going to be something
serious, such as the gear box or crankshaft. I had already checked the wooden
prop for tracking and balance. The gearbox had clean oil and no sign of metal
found on the drain plug magnet. The ignition timing was within .004" of the
prescribed .086" BTDC. As soon as I removed the cylinders I saw that the
piston domes were "thickly" covered with carbon. My last decarboning was done
less than 60 hours ago and I didn't think it would accumulate that much in
that time. But it did. I cleaned it all up, installed new gaskets, and took
it back to the airport. One flight around the field and Yeaaaaaa, its
sounding good again.
Thanks to all who responded with suggestions on what it might be. It gave me
things to look at before dismantling. So lets see, I guess I'll go and get me
some of that SeaFoam!

Hi Bill and Kolb Gang:
Just curious about all that carbon. I never experienced carbon buildup and
never decarboned a Rotax 2 cycle eng during my two cycle career (except
during rebuild). I reckon I just blew the carbon right out of them as I
flew. However, I never babied my two strokes, never cruised less than 5800,
and yes I did take them on nice long XCs often. I think long XCs at a
respectable power setting of at least an hour or more are necessary to keep
these little hornets happy and clean. In addition, every now and then, mine
got a shot of Marvel Mystery Oil in the fuel tank.
I have noticed with regularity that my 912, as well as the two strokes, that
are flown only locally playing around the patch, tend to get lazy and lack
that sharp crisp feel that they should have. They get to where they don't
want to idle smoothly and just get plain lethargic. I can go on a descent
XC and the first landing I can tell the difference. Just like giving them a
good enema. Cleans them out. On this flt to Quincy, Florida, I put 16 oz
Marvel Mystery Oil in 25 gal (twice the recommended oil) and after a couple
hours she was back to her old self. More power and much smoother. Not
trying to sell MM Oil, but I have used it since 1964, when I purchased my
first new Honda 305 Super Hawk. Used to put a cap full in every tank. Did
it do any good? Back then I don't know, but I use it now in a 351W marine
engine, Dodge Cummins diesel, Kubota diesel, Onan 4 KW generator, and the
912.
Besides, it smells good!!!

Hello Kolbers,
I haven't been to active in this list but have definitely read alot of
good advice. Our MkIII is coming along nicely, we have all of the tail
pieces built and temporarily installed on the fuselage tube (It looks
like a huge lawn dart).
I ran across some information last summer concerning covering and
would
like some opinions. There is a company in Ennis, Montana called
"Aircraft Finishing Systems" that sell a water born finishing system.

Their Email address is afs(at)3rivers.net if anyone would like the
information.
Also I have been playing with a web page of our building progress if
anyone would like to take a look and make some comments. It can be
found at http://www.digisys.net/users/paulv/kolb.htm
Happy ThanksGiving

| Subject: | Re: Floats and gross weight |
Hi,
I'm interested in putting my FireFly on floats; maybe a Full Lotus
monofloat. It seems like a Full Lotus Monofloat 1000 would be
sufficient, but the FBO at a local airport has a few used and new
1700 and 2000 Full Lotus monofloats which he just aquired and is
interested in selling (he doesn't know what he wants for them yet
though); would something like that be overkill for the FireFly?
As a rule of thumb use a float system that has a bouyancy of twice the
gross weight of your plane including the amphib weight and mounting
hardware.
If I do this, it would definitely have to be an amphib setup; I don't
want to be stuck with land or water, I want to use both... According
to Full Lotus' web page, the 1000 and 2000 can be set up for amphib
(pricey!!!!! $$$$$$) :-( but the 1700 can not. (Any less costly
options here?)
My experience with the MKIII on floats is to stick with Lotus Floats since
they absorb more impact force than rigid floats and the tubes are easy to
replace.
I would not pinch on the float cost but would look for someone that can
make a home build amphib system. My experience with the Lotus amphib system
has been less than satisfying.
My main question though is... I'm already at gross weight for
my FireFly. Actually, I'm slightly over, maybe 520-530lbs and
I believe the gross weight for the FF is 500lbs. Does adding
floats affect the gross weight? Obviously they'd add weight,
but I thought maybe they act as a "lifting body" which
would offset it... ?
The amphib system of a Lotus Mono float weighs about 35 lbs. Float weighs
around 45lbs and mounting hardware should be 15 lbs. Total added weight 95
lbs.
It all adds to the gross weight and drag coefficient of the plane.It
requires 25% more Hp than std engines for decent water take-off and climb
performance due to the added drag and weight. As far as "lifting their own
weight", the stall speed of my MKIII with duals appears not to be affected
by them compared to what other MKIII owners have reported but I believe
that once in the air, weight is weight!
Oops, I thought of another question: How does the monofloat
attach to the plane? Is there a mounting kit or something that
I need to buy from someone? (Kolb?) If so, anyone know
what it costs?
Although there are Kolbs with monofloats around I do not know of anybody
selling a mounting kit. If you can build a Kolb, attaching a monofloat is
not that difficult.The amphib hardware and mounting hardware all should be
combined in a single design.Kolbs also require a retractable waterrudder
for decent turn control on 10MPH+ wind conditions while taxiing on the
water.
Ummm, one more question. :-) If I were to get my FireFly on
floats, I've played with the idea of registering it as an experimental
so that I could build float time (for reduced insurance premiums, etc).
Is there any problem with using Full Lotus floats on an Exp. aircraft?
Any "gotchas" to look out for here with registering my FF as an Exp
floatplane in general? (I am the 2nd owner, and not the original builder.)
This has already been answered correctly. BTW, when I registered my MKIII
as an amphib,the FAA inspector had checked their records to make sure I had
a float licence before coming out to inspect it.
Any info or advice on any of the above would be greatly apprecated.
I personally think that monofloats with sponsons on Kolbs or any other UL
look ugly and it is difficult to get into the cockpit and use the plane
around other boats and docks but if all you use it for is to beach it maybe
you are ok with it.

| Subject: | Re: Quincy, Florida, Flyin and BBQ |
Hey John, Glad to hear you made it home okay. Richard and I left about 9:30
while
we still had a high ceiling. The prediction was for more rain down in P.C..
We both had things to do today and had to get home. Sorry to have missed
you. Rut took us to breakfast early in down town Quincy. We picked up some
gas for our trip home. When we got back Rut, his girlfriend (Deana) and I
got to go up in the QS that belong's to Charles Davis. He's an ASC- BFI .Boy
did that bring back memories when I use to train in my QS. Not a good X-C
machine but a great trainer.
The food and company was terrific and I must congradulate Rut on his first
gathering. He's only been doing the UL thing for a few short months and he
has already accomplished more than most UL pilots do in their entire flying
life. "Way to go Cowboy, YEE-HA".
Richard, Rut, Deana and myself took over the FBO after everyone left that
night, made a pot of coffee and watched every movie we could find that had
airplanes ,collected by the local EAA chapter. Then we watched "
Independence Day " again because it had airplanes in it. The rain had been
light all afternoon as you know.
When we finally called it a night , Richard decides to take his sleeping bag
and sleep in the FOB on the couch. The minute I get comfortable in my tent
the rain started and didn't let up for five hours. It was nice and not to
cool. The water repellant I got from Wally World did the trick on my tent
because I hardly got a drop inside and sleep like a log for most of the
night. I can tell Richard's days are numbered when he sets up his tent and
then takes the warmth of a cozy coach inside just because of a little rain.
To bad I didn't think of it first. But then he's only 71 years young with
2000 hours in UL's. I guess he's entitled.
For those who don't know Richard Lovel (AKA Bluebird) my wingman. He
started flying UL's sometime after he retired from the Airforce, where I
might add, he drove recovery boats to pick up downed drones and lots of
other assorted things from the waters south of the Florida panhandle. He
flew a QS 'til he wore it out then a Fire Star 377 but couldn't wear it out
after some 800 or so hours, no rebuilt engine either. He was looking for
something with more room back before the FSII came and settled on the
clipped wing Challenger. You wouldn't believe how much stuff he can get in
there. He probably would be flying the FSII if he had known it was only one
year away. Never the less he has 800 hours already on the Challenger and
it's still going strong. This guy just loves to fly. If there is any chance
to fly on any given day he will be in the air if it's only to fly the
pattern. He says this is his last airplane but our friend John Wayland is
about to bring his new Sling Shot on line to taunt him a little. Finally he
will beone of the slow one in the group for a change. He'll have a lot to
think
about on those long X-Cs we are planning. Texas, Arizona, Indiana, Kitty
Hawk to name a few. He is a world of information on X-Cs and where to go
and what to avoid, but most of the time you have to ask , maybe it's because
he feels it's more fun to discover things for the first time on your own
rather than knowing the end of the story before you get there. He want let
you get into trouble but he will let you experience flying the way he and
John W. did a few years ago.
Hopefully I can join them again in their quest to cover every square foot
of the southeast with a UL.
Anyway we got home alright. Ran into a little rain and low vis. just west
of Clarksville and had to descend to 1000' but no problems. It was right
after I sat down at P.C. that the rain came in earnest. We'll do it again
next year. Maybe more can fly in, as it was I am glad we all had a safe
flight
and a very good time. FIREHAWK

Hi Ray;
One more idea for you to consider; I cut mine in half length-wise. During
the construction process, I placed one of the halves on top to the fuselage

I guess he's really gone to have missed this bit of humor!
But seriously though, UL motors may be their Achilles heal for a lot more
folks than just Rusty. The caution to keep an emergency landing site in
view constantly, that it's not IF but WHEN the motor dies, is a huge
disadvantage to the UL community.
I saw a Wankel display at Oshkosh - very interesting. Expensive! Had a
60hp twin rotor mounted in a go kart, but never saw it run. They also had a
static display with a prop setup which seemed to work OK, but the whole
prospect looked a bit premature. And very expensive! I guess that, and
weight, are the main reasons 2cycles rule.
Wonder about that BMW boxer conversion I've heard about...

I don't think it is exactly huge. Definetly a factor, but 2-strokes
can be kept pretty reliable. Main thing required is knowledge of what
they want, and then the diligence to treat them right. 2-strokes are
sorta dirty, loud, need oil added to gas, and deliver unwanted vibration
to plane and pilot. With all that, and an ultralight's ability to land
in little space means reliability isn't the top of the disadvantage
column as far as I'm concerned. Of course I may change my tune when mine
decides to go quiet again someday.

Duncan and Gang:
I use a 70" dia 3-blade prop on my MKIII/912.
Don't know what the boom clearance and total height is. Have to go to
airstrip and measure.
Two blade prop would give you a lot more clearance than 3-blade.
My 912 is about an inch lower and 1/2 inch further forward than the factory
mounts.
Next time I go to Gantt Int AP I will try and remember to take a tape
measure and get the info for you.

You should make it. My 912 MKIII with a 70" warp drive would just make it and
my garage door is 83" high as well. Turn one blade straight down and the others
will be a little lower.

No trouble with throttle linkage. Be sure you have the throttle lever for the

Michael,
Loved your story about Richard. My wingman is Kenny Mancus. He is 73 years
of age and will go flying at the drop of a hat. Has a KXP with 600+ hours
since spring of 92. One time I got up real early and flew over his house. He
came running out, never looked up to see who it was, just jumped in his car
and raced to the airport. He almost beat me back there. It was going to be a
windy day, so rather than set his plane up for such a short flight, I asked
him to take a ride in mine. What a joy it was to see the smile on his face.

Hi Michael,
The prop is a Tennessee, wood, 66 X 30, clean it after each flight, looks like
new. Had checked tracking and balance before removing engine and both were
good. I usually cruise at 4800 to 5000 RPM with this prop (to keep up with my
buddy who has a KXP 447 with 66 X 32 and turns 4500 most of the time). My CHT
about 250 and EGT indicates 1100, sometimes lower. Plugs are a nice light
chocolate brown color, so mixture appears to be not overly rich. But
apparently something is making lots of carbon. I'm using Castrol Super
snowmobile oil @ 50:1
I know the reccomended prop for this engine is 66 X 28, but when I originally
got my kit it had a 66 X 32 prop and I flew with that one 3 years. And I
turned less RPM, in the 4200 to 4500 range The EGT then was really low, in
the 900 to 1000 range. It didn't seem to make as much carbon, but it did make
it and I decarbon every winter when its to cold to fly. I mostly use Amoco
fuel, but have also used others on occasion. Guess I'll have to start
experimenting to see if I can reduce the carbon buildup. Funny thing is, it
only gets on the piston dome. The heads are clean!

Hey John,
Sounds like one of those fun trips that keeps a smile on your face for
several days. I didn't realize a 2 up loaded MkIII would climb so well.
Hmmmm, you got me thinking too. I'm not really seriously thinking of
getting into another airplane yet, but last night I read an old review
on the Avid and Kitfox. I've wondered how they stack up as competitors
to the Kolb MkIII. The review article was not kind to either the Avid
or the Kitfox, but it was perhaps written from a standpoint of someone
used to a hands-off XC cruise plane. Most of us I guess prefer the
lighter controls and a little yankin and bankin once in awhile.
Any/all comments on these three planes?

To all,
I got in a hour or so today after I changed out the half doors for the full
doors and enclosure. I felt like I was in a spam can again... almost. The
visibility was limited with some foggy scud clouds and the overcast was at
1.5K' - 2K'. The wind was not a big factor. I don't think I would have
flown in unfamiliar territory today, but I know that area very well so up I
went. I did a circuit at my home airport and then flew over to a lakeside
airport about 15 miles away to practice on their grass field. On the way
over, I checked the GPS against the ASI to see if changing the doors had
made any difference in the indicated readings... no difference, but still
way off actual... no matter. I have been careful to try to run my rotax at
least 5800 rpm (as suggested by J.Hauck). That "putts" me along at about
70 mph... depending on how trimmed out I am and how rough the air is.
Today, the air was relatively stable considering all the cloud activity...
no sunshine to cause convection currents I guess.
When I got back to my home airport I made my first 1/2 flaps landing. I
was pretty high on final and rather than just dump the altitude with the
flaps then retract before landing I just left the flaps deployed. I kind
of liked the extra drag and shorter float they provided. Now that I have
over 50 hours, I will begin to experiment with them some.
I checked the main wheels and they needed tightening... one side only 1/8
turn, the other 3/8 turn... to bring them back to "non-wobble" "not-tight"
snug. I also tightened the cable brakes a little. I needed a little more
stopping power. After all the talk about hinges, I oiled mine a little.
Talk about quick light ailerons now... sure, dream on...
I discovered a screw up on my part and I have no idea how long I have been
flying this way. The last time I loosened up the wing gap seal (probably
to take off the rear enclosure last spring) I failed to slip the hold down
hook into the tube that holds the center rear portion of the gap seal down.
I have been flying that way for awhile with no problem. I could see where
the hook had rubbed paint off the tube and where the gap seal had risen up
to touch the muffler (I have an aluminum plate there to protect the Lexan
from melting) and other engine parts, but the rear springs did their job as
well as the "hook" and held everything in place.
I gave the radio some more use today and I am very satisfied with the clear
reception from other aircraft. I feel I am transmitting pretty well now,
but so far have only tested once. Whatever... nobody was complaining
today. Enclosing the Kolb does reduce the decibels due to wind noise...
maybe even the engine a little and probably helps my transmissions.
Shielding the plug wires helped some I know... no more stacato noise rising
and falling with the rpms. Getting a good headset adaptor made all the
difference.
I am a happy camper...

I agree 100%, and even minimize ithe impact of quietness more, and certainly
do not consider "engine quiet" as a curse. Actually I consider the engine as

7.9:1 with the engine at idle and airspeed of 42 mph approx.To me flying an

Gentlemen, I would someday like to see a study done on 2-cycle vs 4-cycle
reliability. I think at this point in history, the 2-cycle would really
give some startling aviation statistics as far as trouble-free hours for
the amount of time flown. Carbon buildup will always be the downfall of
these engines, but now that we all know about Seafoam and other such
additives, these little hummers could really tip the scales on the fours.
I'm impressed with all the hours flown by you guys and others using the
2-cycle. The four cycles do fail too, even those expensive Lycomings,
because they have many more parts that go wrong. Maybe there is something
to be said for simplicity ....... it means reliability.

Don't fold the wings up, take them off. I take the wings completely off my
MKIII when ever I need to put it in the garage for maintainance, etc. You
are only pulling out one more bolt, it is no big deal. It adds maybe 5
minutes more when I put it back together.
I have made a couple racks that hang from the garage roof, and just put
the wings in them. Heres how they work: Get a 6' length of 2 1/2" or 3"
pvc and hang it from the ceiling in a level attitude about 10" below the
ceiling. This is the support for one end of the wing. Put a screw eye in a
rafter and tie a heavy cord to it. Get a 6' length of 2 1/2" or 3" pvc and
hang it from the cord at one end. Put another screw eye in the ceiling at
the other end of where the pvc will go when you swing it up level. Put a
loop of cord in the screweye.
When you carry the wing in, ease one end of the wing over the level
hanging tube. Then go to the other end of the wing, where the pvc is
hanging vertically, and swing it up level to support the wing, and slip the
loop over the end of the pvc tube. Done.
Caution! Stits paint does not resist abrasion for beans. Don't slide or
scrape the wing along the pvc, or it will rub through the paint.

Well Kolbers:
Reliability is relative whether two or four stroke. If it is running it is
reliable. If it ain't it is unreliable. Most of the problems I have had
with either type eng was my making, or failure to check what someone else
did. Two stroke was sparkplug wire falling off inverted Cuyuna, paper fuel
filters, fouled spark plug. 912 only quit when I got a couple gals of water
with 10 gals of gas and I failed to drain fuel prior to takeoff. Course the
eng didn't stop on the ground, it waited til I was most vulnerable, a couple
hundred feet in the air in a hard climbing turn. Was able to get her turned
360 deg and land where I had just departed. Lake Texoma, Texas, last Jun,
got the first ten gal of fuel from new fuel tank, filter, pump, hose and
nozzle. Was lucky, didn't lose eng until about two hours eng time after
refueling. Fuel filter packed up completely with debris, shut off fuel
supply and eng twice. Lucked out and got it on the ground again
successfully. Only time the 912 everstopped in 985+ hours.
Had a 582 seize, never determined cause. This type failure bothers me more,
when it comes to reliability, than flying with the 4 stroke. Haven't heard
of any 4 stroke siezures. This 582 seizure gave me no warning signs, feel,
sound, or instrument readings, no clues that it was impending. I still fly
2 strokes and don't sit on the edge of the seat when I fly them. They have
given me good service and reliability.
One of the biggest factors to fly a 4 stroke is economy of fuel, oil,
sparkplugs, and teardowns. If one flies enough it will make up the
difference in purchase price with economy.
Yes, if it is mechanical it may break, no matter what it is.
Was taught in flight school to always have a forced landing area in site.
Still an important safety factor.

As an interesting aside on 2-stroke reliability, Duane Cole's video, "VFR

Hisself advises that he always flys evaluating the terrain ahead so that
given the choice, he has a good flat field within gliding distance in case
his Expensive Genuwine Certified Aereoplane Engine quits. And he says he
normally alters his flight path right and left to give himself an out just
in case. Maybe that puts things in perspective?

it get wet or when was the last time a front came through your place or did
you leave the prop vertical the last time you flew before you noticed the
vibration? It's funny how one answer can lead to a whole lot more questions
ain't it? I don't know about the snowmobile oil your are using but I bet if
you were to switch to Pennsoil 2 cycle air cool oil and run it a little
harder it wouldn't have a carbon problem. I use to the same problem with a
different brand that works great in a lot of other engines but I always had
a carbon problem too. Then I called John Hunter at Lockwood to find out what
they used in their 582's. He told me that Rotax recommends Pennsoil (air
cooled) in all there aircraft engines regardless of whether it was air
cooled or liquid cooled because of the way they are run ( long periods of
sustained and steady RPMs and similiar temps). This was after my brother had
put some 800 hours on a Lazair with the 9.5 HP Rotax's using Pennsoil with
out a rebuild. Then there was my wingman Richard who has always used the oil
and has never had a problem. I wasn't satisfied with the evidence that they
gave me either. I had to try something different also. Guess what ? I was
decarboning every 100hours or less. I probably should have done it at 50
hours. I have 250 hours since the top end (this is where I started using
Pennsoil) and it is still going strong without a decarboning. I don't have
any of the other problems that goes along with carbon buildup either like
hard cranking from the rings being stuck on the pistons and smoot black
plugs, which I had to change a lot more often. Richard had even gotten to
the point that he would not even crank his plane around me until he was sure
I was cranked. I spent many times hand proping while he held my plane. We've
not had to hand prop but once and that was from a dead battery since I
switched. I am convienced it was the switch to Pennsoil. I also use the
injection system that is still set from the breakin.
How many hours do you fly and how often? Did you know that wood props
absorb water and that it can migrate to one end? I have a wood prop I use as
a spare. In case of emergency only. I know it is as balanced as I can get a
wood prop but compared to my IVO it can't hold a candle to the smoothness or
quietness.
The whole plane benefits from the lest amount of vibration that can be run.
That old wood prop liked to have beat me to death on our trip to Nulltown,
In. last year while the IVO was being repaired. After that trip I decided to
stay home if I couldn't have the IVO.
I know there are pros and cons to all of this and would like to hear from
the rest of you. Who knows there might be something out there you are using
with great results and we would all benefit from it. All for now. Thanks for
the return. Firehawk.

John: You get alot of respect on this list and you deserve it. But let
me offer the following. Again, it is NOT my intention to give you a hard
time. Several years back at lakeland I was doing my annual tour of the
certified rotax repair guys' tents. Every year I go talk to these guys and
ask them about the failure modes they have seen in different engines,
principally 582 and 503 because that's what I fly. My experience is that
engine rebuilders are a much more reliable source of good information about
failures than pilots themselves. Anyway, the guy from Greensky (I think)
offered to sell me a brand new freshly rebuilt 582 which he said had something
like 5 hours total time on it. I said gee, why was it rebuilt after such a
short time? The guy knew I was a Kolb pilot, and he sorta shuffled his feet
and said well, one of your better known kolb pilots seized it up. I said
jeez, how did he do that? The guy replied, well, this pilot thought that
Marvel mystery oil was good stuff, so he put a little in the gas. That worked
out good so he decided to put a little in the injection oil. Well what most
folk don't know is that marvel mystery oil is mostly solvent and perfume with
a little high grade lubricant. The pilot put in enough that it screwed up the
oil/fuel ratio and he seized the engine due to lack of lubrication Anyway, he
said that guy was you.
PLEASE DON"T ANYBODY SHOOT ME!!!! I'M JUST REPEATING WHAT I WAS TOLD.
However, even if this story isn't true (which I repeat it may not be)
there is a lesson to be learned from it. We are all tinkerers or we wouldn't
build our own planes. Every kolb owner has customized his plane to some
degree and as his own way of doing things. This is fine except that there are
limits to how far we can deviate from "doing it by the book." There is a
whole category of accident which happens in this category of plane which
doesn't happen in GA planes. Example: a guy a my field with an early firestar
found his plane to be nearly uncontrolable after he changed the frame tubing
around and moved the gas tank to "make it look cooler." When do you think the
last time was that happened with a c-182?
My point here, and I think I'm in agreement with John, is that when it
comes to operating Rotax engines most of our wounds are self inflicted.

Hi Eugene:
I wish I could say I religiously follow the principle of having that forced
landing area in sight, but I get complacent and find my self in situations
where I would most definitely be the loser is I lost an eng. I have never
lost an eng when I expected it. It always comes as a complete surprise.
In the days of 2 stroke flying I practiced what I preached. I think the
fact that the 2 stroke quit more frequently made a better pilot out of me.
Also in those days my XC flying was done with mag compass and sectional.
That also made a better pilot out of me. Today with the GPS I get lazy
because it is so reliable. I try to keep up with my progress on the
sectional most of the time. Coming out of Kankakee, Illinois, to Joliet and
Oshkosh this year I lost the GPS. Shocked me right back into the real world
in a flash. I had to fly pilotage and dead reckoning to Joliet before the
GPS decided to cooperate. After I got settled down to busy, I realized I
had been missing out on some good flying. All I had to do was watch my
airspeed and altitude, read my sectional and follow my route on the ground,
as I cross checked the mag compass. I wasn't worried about ground speed,
ETA, or staying precisely on course. Given the choice though, I'll fly with
the GPS as primary nav aid. It saves time, gives me a lot of emergency
options, and makes my XCs safer, which translates to more longevity and the
opportunity to continue flying.

Hi Gang:
I think you are talking about Gerry Olenik, owner of the oldest Rotax
dealership in the US. I've done business with him for years, however, Gerry
didn't get involved with my 582, except to sell me pistons, rings, and
gaskets to rebuild it. I had over 200 hours on this eng, flying to
Lakeland, Homer's in Pa, and Oshkosh. This was a new eng I got from Homer
when I built the MKIII. Flew it the same way during its entire life, with
Marvel Mystery Oil since day/hour one. Seems to me, if it was the MMO that
caused the seizure, it would have happened early on. Put about 1200 hours
on my Cuyuna and 447s, all with that shot of MMO. The 582 is the first and
only 2 stroke I have ever seized, including a fist full of MX bikes,
outboard motors, and my weed eater.
I swapped the 582 for the 912, but I went south instead of north to do it.
I dealt with Ronnie Smith. I guess stories like this are part of the little
bit of notoriety I have gained over the years.
I think I mentioned in a recent post that I doubled up on MMO for my flight
to Quincy, Fl, and return. The 912 has ingested a lot of that stuff over
the hours, also my Dodge Cummins Diesel, Onan generator, and the 351W eng in
the old Searay. I swear by it. I wonder if it would work on my
arthritis??? hehehe
Did you guys know if you keep a four stroke eng bogged down, running below
the power band, that it will carbon up, get cranky, lazy, and weak? Don't
you know how much better the old buggy runs after you take it out on the
Interstate and blow that sucker out for an hour or so. Two stroke engs are
just like deem 4 stroke engs when it comes to getting clogged up with carbon
and gunk. I read on this list of making these poor little engs fly around
at 4500 to 5000 rpm their entire life. Then when they get gunked up with
carbon, cannot figure out what they are doing wrong to cause this terrible
condition. It is pretty simple to me, it is your left hand, the one you
have on the throttle. The rotax 2 stroke is not a tractor (farm) eng, it is
a high performance, high rpm eng that spends its entire life loaded/going up
hill all the time, even when it is idling. It has an expansion chamber
exhaust system that is designed to make the eng efficient, both power and
economy, somewhere after 5300/5400 rpm. I always found with the 2 stroke
(Cuyuna, 447, 582) that they all like to run 5800 rpm cruise. At this rpm
they are smoother and the internals will stay significantly cleaner.
OK, I can only talk, with experience, about 2 strokes up thru the early
90's, but I bet they haven't changed all that much since then.
Just my own thoughts and experiences friends. This ain't the gospel, but it
has worked for me, and it is still working. If it changes, I'll let you
know.

Good point David.
The typical terrain around my area makes it easy to fly a 2-stroke.
I'm not sure I'd have the nerve to fly most of the time over mostly
unlandable terrain.
Another little point about keeping an emergency landing field in site: One
of the things I find a little bit of a game is to keep track of the good
em fields that go behind you. When I give myself the quick pop quiz of
"alright! where is the best spot?!", i often find I select something
and a few seconds later realize a far better spot is right behind me
within easy glide. Makes me pay attention ...until the day dreaming
takes over again. Day dreaming requires higher altitude, and sometimes
it is easier just go up to get that bigger margin of comfort.

Right on, Ben:
You can't beat altitude for that added bit of safety.
If I have to cross "bad stuff" I get altitude.
One point to remember if the fire goes out, choose a good forced landing
area and get set up to land in it. If you see a better one and you have a
lot of altitude and plenty of time (and this area you know you have made)
then change, but it is usually much better to select the site and land in
it. Bill Griffin, on this list will probably more than happy to tell you
what can happen if one is not decisive.
There ain't no go-a-rounds,

Hey Ben. If you guys are Kolbers does that make me a Ferber?
Amen on the bigger picture Ben. I can relate from my on experience that an
engine out at altitude is a lot more forgiving than one at low altitude. The
options are much better and you have time to think, what the best coarse
of action is. That difference in time can make the difference in whether or
not you make it or break it. In my training course , I try to instill into
my students to always have a spot picked out within the cone that the
airplane always sits on in flight. The outer edge of the cone is at a 45*
angle down from the plane. It may be overkill for some pilots but this will
usually work on any airplane. I believe in the "WHEN NOT IF " saying about
engines, all of them. Just the other day a student pilot an his instructor
had to put down on a county road north of here because the Lycoming in the
C-150 quiet. Funny thing is I had to practice emergency approaches on that
same road when I went for my private.
I'm getting like John about this stuff. It's almost addictive. I wonder if
there is a support group for E-mail addicts on the "Internet". All for now.
Firehawk.
P.S. I definantly agree with the MMO that John uses. I use it from time to
time as a gas additive. Sure helps to keep thing clean along with Pennsoil.
But
I don't mix the two, something a Pennsoil Rep. said one time " It may or it
may not mix but do you want to take the chance?'' I think he was refering to
outside temperatures and the way the viscosity is different in the two oils
not readily mixing.

I take it that you installed the rings but not the holes & covers?
If holes & covers, that seems like a lot to me. On the other hand,
I think there should be *some* holes and covers to be able to look inside.
I installed 2 rings/holes/covers on each wing:
- 1 on the bottom of each wing where the lift+drag struts join the
main spar -- a key spot to be able to get a visual on at annual.
I just love to look at that home-made AL box where they join cuz
it is so impressive how you can get so much strength out of thin
AL (!). Also, I could get a wrench on top of the big spar bolt
if I needed to (or somebody with small hands could).
- 1 on each wing root just behind the main spar to peek in on the
drag strut and it's steel braces. For the wing root, you could
cut it and patch it annually but rings seem more the right way
to do it.

I just installed the rings. If I need to I will I will cut them open and put
in a cover. Perhaps at my first annual I will cut open the hole by the lift
strut to check. The big benefit to the rings is that if you ding your wing
you can cut open a nearby hole and see how bad the damage is without having to
take all the cover off.

Yes but why? I have never pulled the wings for storage and have never

David, what I meant by "flying by the engine" was disregarding some common
sense dealings with the hard spots, namely the ground, or other hard barriers.
For instance, when you fly near the "granite" (mountain, hill) it would be
adviseable to stay on the windward side to take advantage of the prevailing
air currents for lift, just in case the engine did quit.
Instead of coming in for a landing at a constant 1.3 degree
declination like a GA plane might at a big airport, stay high enough to always
be able to pick an alternate landing point , until you finally clear the final
impediment or barrier such as telephone lines before "aiming at the ground" or
slipping to the ground. Yes you will land hotter and longer but always
safer.(unless of couse you blast yourself into the woods at the other end of
the too short runway!!) I think I hate that when that happens.
Know the wind strength and direction at all times to be able to
estimate how far you can glide if the engine quits now....no, I mean ....now.
My L/D is 7.9:1 on an engine idle ( therefore it is probably better than that
when the prop stops completely), therefore I can go almost 8 miles on a dead
day if I'm up one mile, and that is like money in the bank for engine failure.

the leading edges are so close to the ground when it is folded, that they
can readily drag when you go over a hump, or where a ramp meets the
trailer. His leading edges were kinda beat up.
I am glad I did not provide for my wings to fold, so that I am not
tempted. Besides, empty weight is 513, with 15 gallons of fuel, it is over
600 pounds. Trying to push that across the back yard to the garage would
wipe the Old Poops out. It is heavy enough with the wings off.
Besides, the only time I put it in the garage is to do maintainance. And
the wings would be in the way.

Hi Michael,
I know what you mean about moisture in the prop. I fold the wings for storage
after each flight and the prop is always placed horizontal, so it shouldn't
get out of balance from that. Besides, balance was one of the first things I
checked. I just might take you up on the suggestion of using Pennzoil. I had
originally started using that oil, then the Castrol became easier to get
locally, and its a good oil, but maybe it is part of my problem. Trouble is,
if I change too many things, I'll never know for sure which made the
difference, if any change at all. And it takes at least 40 maybe 50 hours
before a decarbon is needed. I had about 60 when I noticed the problem.
<>
Well I'm sort of retired, so I fly about twice a week, depending on the
weather. First year, 1994 I only flew 30 hrs. Since then averaging about 70
hrs per year, and now have 305 hrs. on it. I'd even fly more often, but I
have to drive 35 miles to the airport. That takes 1 hr each way due to
traffic and back roads. Then it takes me 1/2 hr to set up, fuel up ,etc.
Then another 1/2 to tear down and clean up, etc, So I usually don't go unless
I can fly at least one hour or longer. Been on several cross country trips of
1-1/2 hrs. each way.
Thanks for your input FIREHAWK.

On this list, I have been reading a lot about cold seizures, hot

with our 2-stroker's.
I'll preface what I wish to ask with: In this area, the east kern
portion of the upper desert of southern california, there has been no
known seizures. I know of one person with a firestar & 447, who waited
until he had 632 hours on the engine before he broke it down. He only
found some minor scratches in the aft piston area.
My question is this: What oil are you using in your mixture's. I
would like to know if there are any seizures using the av-2 oil?

When I built my Original Firestar I wasn't aware of the aluminum replacement
for the fiberglass tailwheel rod. However, now that I am flying it I see
that the replacement is needed because the tailwheel flexes sideways when
turning.
My question to the group is: What is the best way to remove the epoxied-in
fiberglass rod? Naturally, I don't want to damage the lower fin in doing
so. The use of heat is out of the question so I assume I'll have to cut off
the rod near the lower fin and drill a pilot hole as close to center as I
can. Then follow that with progressively larger drills. Is there some
other way?
Thanks,

Here's a little thing that happen to one of the guys on our field as
described by my partner.
They had a fly in the area on one of the most beautiful days I've seen in a
long time. Crisp with radiant blue sky, little wind and I had to leave on
a flight that afternoon so couldn't attend. My partner flew our FireFly in
and had a great day.
Gene, one of our buddies on the field missed out on the fly in. Seems he
suddenly developed noise in his engine (a 447). Later found
out that one of the brand new spark plugs had broken off some porcelain near
the electrode. Put a new plug in and the noise went away for a little
while. He ended up pulling the cylinder and found the broken hunk of
porcelain in the cylinder. It had beaten up the piston top, which he
smoothed with a dremel tool. He's ready now to test fly it.
Talk about luck.

Happy Thanksgiving Kolbers:
Jerry, I don't really know how lucky your buddy is. If a piece of porcelain
beat up the top of the piston, it had to have something to beat on, and that
would be primarily the cylinder head, and possibly the top ring.
Depending on the severity of the damage to the top of the piston, I might
have considered replacing it with a new one. Dremel tool equates to
grinding and grinding equates to loss of mass and weight. Might prove to be
a problem.
I used to balance my pistons, rings, wrist pins and bearings. There was
always enough difference in their weights to make a difference in the
vibration level of the 447 and 582. Just food for thought.

Hey Bill, Sounds like you got it under control. If you call the Pennzoil
people they will put you in touch with some one in your area.
70 hours a year, huh. I can see you are a dedicated flyer when you have to
drive all that way and then set it up.I must be one of the few that is only
5 minutes from my plane. I use to live 10 minutes but that was to far and it
took too much time to get to the airport. So I built me another house closer
and then sold the other one. Now I,m thinking about building a house on a
new runway north of here where I can just walk out the back door and get in
the plane and go. I dream a lot too.
Bill, I have a wood prop that I use as a spare and another that I have on
my Fisher 202. I have never been able to balance them satisfactorily. Would
you mind telling me how you do that ? I bet there are a lot out there that
would like to know. I've used prop balancers and they don't seem to give me
the balance I am looking for. There is always this low frequency vibration
that can only come from the prop. I guess I'm spoiled by the smoothness of
the IVO.
I was out flying around this afternoon just checking that bolt I torqued
for maintenance, I am just amazed sometimes how good it feels to be able to
fly. It was so smooth and no one else around. John H. mention that he uses
Marvel mystery oil in his mechanical things, I do too, mostly the Gas add
treatment. My Dad used it in all his machines too, way back in the 40's and
50's when we used to run a sawmill in Southeast Georgia. I was only 4 or 5
years old when I was introduced to it. We had our share of break downs but
they weren't usually from the engines we ran. I remember when my brothers
bought the old sawmill from Dad they used the same old Red Seal power unit
flat head 6 cylinder, gas ) that ran the mill originally. That was some 20
years later. After a little cleaning and adjusting the old thing could be
hand cranked in one throw. It came with a built in crank handle just like
the old Model As. I remember being so small that I could hang on to the
crank and it would only move as the compression leaked down. Man to me that
was a long time ago.
The old place we grow up is a car lot and a mall now. I used to fly my U-
control plane where the mall parking lot is.
Listen to me rattle on. We were talking about planes. I hope that one day
we can all met from time to time. It can happen. So many stories to tell and
so little time to tell them. Later FIREHAWK
PS Bill is the Castrol you use a TCW-3 or a TC oil?

Hey Jerry , My brother had a relief valve that use to come on the little
185-9.5 HP Rotax, break off and go through the top end. It did the same
thing by imprinting itself all over the piston top and the bottom of the
head. He did the same thing that Gene did. It ran another 400 hours before
he finally stopped flying for medical problems. He has the little engine
that could. FIREHAWK

Happy Thanksgiving everyone...
I happily spent it with my family in Maine...skipped the football this year
to help my dad install a 503 Rotax on his FireStar II project (he's dreaming
that he will fly it before snow arrives!! It would be a safer bet to put
the 503 into his snowmobile!!) We ran into a few questions...There is no
suggestion on what to torque the nuts to on the aluminum plate that attaches
to the crankcase, or the bolts/nuts that go through the Lord Mounts. I read
all pertinent material a thousand times and I couldn't find any #'s...So has
everyone else just tightened it all up until you feel like it will stay
connected in flight, or is there some magical ft/lb # that we should be
aiming for?
I'm a silent reader in this email list...but all of your tips/helps and
"banter" are all appreciated.

For torque on regular nuts and bolts (steel on steel) you can look in a good
repair manual (such as chiltons, or for you engineers out there, "Machinery
Handbook") and it will have recommended torque tables. Remember, a bolt and
nut is actually a clamping device, so the torque is specified to obtain the
maximum practical clamping force without straining the bolt shaft (or threads)
beyond the yield point of the particular alloy. For accurate work, oil
threads before torqueing.

Ron,
I replaced mine years ago by taking a propane torch and very carefully
heating it up and then using a vise grips to twist it and pull it out. My
lower fin did get burned a little, so I had to repatch and repaint it but
it will come out with some heat. BTW, I've been flying off the
replacement fiberglass rod for about 10 years.

You shouldn't oil threads before torqueing. Every manual or how to book
I've seen specifies to torque with dry clean threads.
Also--two days ago I had to heli-coil a cylinder tie down stud on an O-200
that had apparently been torqued while oily or over torqued. The original
threads just pulled out of the case.

Tom, I hate to get argumentive, but I've built quite a few engines, and
have always read to " Make sure threads are clean and lightly oiled.
Torque to spec with a quality torque wrench." Never, ever had any
problems. A small thing to try is to thoroughly clean a head, block, and
bolts. Torque one down dry, and focus on how it feels as the pressure
comes on. The next one, LIGHTLY oil it with a light oil such as zoom
spout, which is a 10 wt non-detergent turbine oil, or 3 in 1. NOT WD-40 !
! ! Torque it down. You can literally feel the difference. Try it,
you'll like it. Big Lar.

Hi Group: I forgot to say that oiling threads works well, but the last
few engines I've built, I've used Bostick Anti-seize lubricant - lightly.
Torques down smoothly and years later comes loose without binding. Works
especially well on exhaust manifold bolts. Haven't had any problems I can
think of with coming loose prematurely. Big Lar.

Hi All: For all this time I've been reading engine diagnosis notes with
some interest. Most of my experience has been with 4 stroke engines, but
for 7 years in Idaho I felled timber with a Stihl 051 AV chain saw. I
realize it's not a Rotax, but it is ( was ) a 2 stroke. You may believe me
when I say we ran those motors VERY hard. No danger of crashing, just grab
the spare saw and fix the 1st one that night. What I remember tallies for
the most part with what I read here. One way or another, seems like we
spent an awful lot of time fiddling with those little Bing carburetors. (
Bing I think, made in Ireland at any rate ) Probably the second most
severe problem is one I don't recall seeing much of here. That is a main
seal sucking air, especially the drive side. As it started, the symptoms
could drive you crazy, very hard to pin-point. As it worsened, it would
get more serious. On a large tree, 4or 5 or more feet thick, which makes
for a long, hard pull, it could suck enough air to lean it out, overheat
and seize the piston. Also seems like that was about the only time we did
seize up. Is this a problem on Rotaxs ?? Or have they figured a way
around it ?? Just noodling. Big Lar.
________________________________________________________________________________
| Subject: | Re: Torque For Engine Mounts... |
I agree with Larry Biglar about his suggested experiment--try the difference
with an oiled thread and a non-oiled thread. One problem is that you can't
really de-oil metal without washing it very thoroughly. For the non-oiled
test, wash with really hot water and a strong detergent ("Dawn" brand picks up
mineral oils best, in my experience), dry with a paper towel and follow with
an acetone rinse. There is a difference, and you can measure it!
Agree also with Biglar on anti-sieze, especially in high temperature
connections where the oil will cook off, and also on steel bolts threading
into aluminum.
