ok this is the real reason airplanes fly... they throw air down at the
earth, which gets mad and reverses gravity to repulse them. this explanes
how a wing can have a lift tio drag ratio in the 40's. how can 1 pound of
thrust generate 40 pounds of lift on a good sail plane? amazing
amplifiers?! no the earth reduces gravity out of spite.

unfortunately you were lied to in your science class along with most people
including pilots in ground school. the asumption is that the air has to get
to the back of the airfoil at the same time. in reality it doesnt. so
although Mr. b's laws are valid and working around the wing and very useful,
the idea that the air over the wing has to go faster is wrong. actually the
air is just sitting there minding its own business when along comes this
wing and swats it downwards.

I'm still not convinced.
When you blow air across the top of a (square or rectangular) piece of paper
hanging from your fingers, why does the paper lift nearly straight out.
There is no downdraft off the back of the paper to force it up and the paper
is not going anywhere. There is stable air beneath the paper that is not
moving.

Didja ever see a thread where I could resist putting in my .02 ?? Several
comments..........1st, on that bit about engine off descent angles; several
years ago I had a couple of hours in an MX II. Instructors advice was to
fly at 300' toward the runway, until you could see the numbers between your
feet. ( No floors ) Then cut the power, point the nose ( front ?? ) down -
WAY Down, and watch the Hall airspeed indicator out of the corner of your
eye, to make sure you were holding 40 mph. Flare when 8' up. It worked -
very well - but he had to make the 1st few landings, cause that nearly
vertical descent psyched me out, and I wanted to flare way too high. Sounds
like what you guys are saying about Kolbs. 2nd. There was a thread a
while ago where I mentioned that many ( I think most ) aircraft are built
with a few degrees of washout at the wingtips, so that in a stall, the root
of the wing will stall, but the wingtips will still be "flying," and give
some aileron control well into the stall. Even so, it's recommended that
you keep the wings level with the rudder, rather than ailerons. 3rd.
My experience and training in the Cessnas tells me that the stall warning
functions according to the "Relative Wind," the angle at which the wind hits
the wing. If you are flying straight and level at a good rate of speed,
every thing's fine. If you then pull the nose up into a steep climb,
nothing much changes, at least for a little while. ( Unless of course, you
really Yank the nose up, in which case it'll stall anyway.) Your speed will
keep the effective angle of the wind at a safe angle. As you slow down
however, the relative wind will start to rotate around and down over the
nose of the wing, until you reach the critical angle of attack, at which
point the wing will stall - every time. I forget the exact angle, (someone
help me here) but I think it's around 15 or 20 deg. to the relative wind.
An extreme example that you can see is at airshows where they have jets
doing aerobatics. When they yank the nose up into an extreme climb, you can
see the vapor boiling in the low pressure area above the wing for a second.
It's thoroughly stalled, at least briefly, and my guess is that it's
momentum that keeps it going until the relative wind catches up. Any of you
aerospace types care to comment ?? I've got a feeling that my neck's hung
way out there, but in any case that's how I understand it to work.
Big Lar.

Larry I made a few comments on stalls also-I try not to say anything but at
times I recognized potential hazards in some of the comments or recommended
procedures from fellow Kolbers on this list,many who I know or have flown
with, I am fully aware of the talent and experience of members on this
list. Over the past 50 years in this business I have followed this procedure
when someone tells me how to do it,or do it better. It is like reading a
book,you agree,disagree, with the author and you use your common sense and
follow a reasonable course of action.
Next time a pilot friend bids you goodbye with the admonition, Keep Your
Nose Down", take it as the sincerest form of wishing you long life.

In making his epic solo flight (with no ground/water support) from
Argentina to Sun n Fun and then on to Oshkosh, Marcello Matocq flew a
LONG stretch over the ocean just off the deck. Figured that when you
are many miles from land, being at 2500 AGL is no advantage to being at
25 AGL as far as gliding distance is concerned, and flying in ground
effect is certainly more effecient.

When all is said and done lift is created by one reason and one reason
only. Namely, the wing must accellerate air DOWNWARD, thereby getting
an equal and opposite force UPWARD on itself (and the aircraft). All of
the discussions about Newton and Bernoulli are simply discussions as to
the MECHANISM that causes the downward accelleration of air.

Another comment on a phenomena I once observed. Our motor home had a
recently installed awning on the side. A long safety strap ran across
the top and then down to anchors at both sides. One day a strong wind
was blowing directly from the side. The strap which went over the
canopy was rather violently flapping up and down and slapping on the
canopy. I went out and watched it and got an idea. I had installed the
strap FLAT all the way across the canopy. Unfastened one end and gave
it a few twists where it went across the canopy and re-fastened it.
Problem solved! No more slapping!
What happened was this. At an instant when the strap was flush flat
against the canopy, the wind was moving rapidly over the top. The air
under the strap (between strap and canopy) was essentially static. This
resulted in a lessened pressure on the top and the strap came up. As
soon as the strap was up, the airflow was essentially the same on both
sides so the "lift" vanished and gravity and tension pulled the strap
back down. This cycle would then repeat itself.

I am tempted to try that idea with airspeed indicator turned into a stall
warning/lift indicator device. Although it is not really an angle of attack
indicator. I guess trying to figure out which would best serve my purposes.
On occasion out here in Colorado I fly into a tight spot or two that looks
interesting and it would be nice to know how close to the "edge" I really
am. I tried the "yarn taped to the side of the windscreen" experiments last
summer. It proved to me that it would indicate the stall angle of attack,
power on or off, but as someone else on the list observed the yarn is
wipping around so much it wasn't too precise. Another problem I located it
down on the vertical side of the windscreen about where my mid calf on my
leg is. I don't really look down there when I am landing or flying too
much so it had limited value as an indicator. With the airspeed indicator
conversion it would give me maybe a more precise visual clue but I am not
sure I have a place to put it. I like the idea of a gauge versus a stall
warning switch since it relays both how close you are to a limit plus the
rate at which you are approaching it. Of course we jump over the stall
limit pretty quick with our low inertia airframes. Anyone know of a source
of cheap airspeed indicators to try this out with?

Gregg and Gang:
How about this:
Use the airspeed indicator as an ASI/Stall Warning/Lift
Indicator, since most of us already have the ASI installed.
Why mount another one to do part of the job? Or am I
missing the point on the AOA/Stall Warning/Lift Indicator
thingee?
Go to altitude and do a series of stalls at 1, 2, 3G's.
Note the AS the aircraft stalled. Then add a couple mph for
safety margin. Does that not do the same thing as the
instrument you all are trying to develope?
I like to "try and keep it simple", which doesn't always
work for me.

Blow on the bottom of the paper. It doesn't get sucked down, does
it.
Kutta-Jukowski, Prandtl's lift theory, and irrotational flow better

The above statement is not entirely true, but close.
I totally agree with Christopher that the air getting thrown
downwards is the "equal and opposite force" that causes the lift,
and that it is due to higher pressure on the bottom of the wing
than the top. In the end they are exactly the same thing, just
depends on how you look at it.
However, the reason a wing is so efficient at creating lift with
a minimum amount of drag is that even with the bottom surface of
the wing completely level to the relative wind, a wing generates
lift! It is not due to a ram air effect.
Although airplanes frequently do generate extra lift due to ram
air effects like when you pull back on the stick and increase the
AOA, the efficient wing does not need to generate all of this
drag to generate lift. Mr. B's law is true, and it applies to a
perfectly flat bottom wing with a smoothly curved upper surface
going straight into the relative wind. It will generate lift
because the pressure is lower on the top than on the bottom,
resulting in a "momentum flux" due to the acceleration of the air
in a downwards direction behind the trailing edge of the wing. (
F=MA is not a magic formula, but I admit that big words like
momentum flux do not originate from my brain. My buddy Rick the
physics Ph.D. and missile designer comes up with the fancy
terms.)
In fact, on a careful analysis of the wing, the AOA is actually
the chord of the wing angle into the relative wind, so that means
the bottom surface can be level or even slightly declining and
still generate lift! It is only when the AOA become zero or less
that the wing develops "negative" lift. Check it out, I am not
making this up. :)

While at the local McGill Ultralight fly-in a few weeks ago, I
met a man that I knew who kept his Kolb Firestar II at the Casa
Grande Airport about 30 min south of Phoenix. He is in his mid
fifties and was a midwestern farmer who visits Arizona every
winter. I kept my Challenger at Casa Grande airport for a couple
winters, and he kept his Kolb in a trailer (how I envied his
trailer!). We chatted whenever we met, and even went off on a
mission once. Nice guy, level headed.
Anyway, I saw him at the fly-in and noticed the big pink scar
exposed on his head. Maybe 5 inches long by about 1 inch wide.
"What happened?", I asked.
Apparently, the engine was idling and he was near the tail doing
something. Due to a smooth surface and maybe a gust of wind, the
plane started rolling away and he instinctively moved towards the
cockpit to shut down the engine (I guess). Well, the prop hit his
head well above the right ear. It stunned him and he fell to the
ground. I guess the plane rolled away?! Someone saw him laying
there and came to his rescue. They flew him in a chopper to bring
him to some major trauma center. He luckily recovered without any
brain damage, but from the looks of the scar, God really gave him
a taste of fate.
I'm not sure what type of prop it was, nor if the prop shattered.
I'll ask if I see him again.
Moral: Smearing brain matter on propellor blades is not a
recommended service procedure.
Oh, and while I'm on it...
The guy who bought my Challenger a few months ago was tweaking
the carbs and such. He is a really good mechanic, but this was
his first airplane. He had the foam seat cushion removed and left
it on the top of the wing (unfortunatley out of sight). When he
reved the engine, the seat cushion slid down and was sucked
throught the prop. Bam! It shattered one blade and threw
fragments all over, and one big chunk though the tail. Luckily,
no one hurt. It was a 3 blade IVO QA prop.
Moral: Props suck.

if Pd is shorthand for pressure differancd: then as lift
increases the Pd would increase. the flaw in this
aproach is "varing airspeed" if you are at stall speed and
you are creating 1 g lift you should be in level flight and
any additional back pressure on the stick would produced a
stall. the results should be predictable. if you were
double the stall speed in strait and level flight (1 g)
and pull back on the stick you are capable of producing much
more than 1 g lift, thus much more Pd
in my humble opinion. there is a company that has a small
device called the "bakon saver" if memory servs. it consist
of a vertical plate with a hole in the front and the back is
marked out in deg. mounted in the hole is a small windvain
that pivits up and down in relation to the relative wind.
true aoa.

Hi Kolbers,
Got a question for ya'll. In the blueprints for the FS II that I'm
building it shows a option that you can install on the outboard ribs to help
reinforce them using 1/2" and !/4" angle (I think thats the size) Can
anybody relate any personal experience about weather this is necessary or
not. I'm not far from the covering process and can't decide if it's
something I should do or not. I will be folding and trailering the Firestar
a good bit. Thanks!!!

ben wrote One thing I'm considering in my rebuild is
shortening my wings,
last year i went to washington to visit my brother and he
took me around to where many other builders had their planes
stored. the one gent had shortened his wings to the end
of the main spar by completely removing the tip bow etc.
at the end of the main spar he added a flat plate on the
end of the wing. the plate was the same shape as the wing
cross section but was about 1 to 1 1/2 inches larger than
the wing. for a test of the two wings performance he flew
with one wing of each style and mentioned that he could not
tell any difference in the two. he was expecting a
difference in both drag and lift but noticed none. the
reason for the change was to have a guard on the wing tip to
advert any fabric damage if the wing tip hit the
ground. hope this helps.

Boyd,
I remember from my old Air Guard days that the F-102 had a vane similar
to that you described. It was mounted on the left side of the fuselage and
pivoted on a vertical plane. It sent AOA information to the pilot.
The guy from Rite Angle is selling one like this. It displays your AOA on
a tree of LED's in inside the plane. These devices measure the angle between
the relative wind the longitudinal axis of the aircraft. The chord of the
wing is
fixed, so this measurement becomes Relative Wind vs.Wing Chord.
My question is: does the "low" pressure on top of the wing change is
proportional
to the Angle of Attack ? Seems that if you lower the nose, changing the AOA,
the
air over the wing changes speed, but is it somehow proportional to AOA. If so,
all we need is a vacuum gauge to measure the upper wing air pressure and
adjust
the stick pressure to maintain the relative pressure to maintain flight.
I'll think about this on the trip to Fun-n-Sun. I'm sure we can find some
Engineer
there to correct us.

In that case the higher velocity air over the paper is generating low
pressure as according to bernoulli, and the paper gets lifted by the higher
pressure static ait that is below it. and guess what , the air that you
blow over the paper gets thrown down resulting in the paper being held up.
whether the air is moving or the paper, makes no differance. otherwise wind
tunnels wouldnt be much use. in the wind tunnel you could say the wing is
sitting there minding its own business and air comes along and swats it
upwards, getting deflected down in the process. them main thing to remember
is that for the air to hold something up it has to be accelerated down.
just like in order for a propeller to move a plane forward it has to throw
air backward. exactly the same thing.

once the wing stalls there is no low pressure zone and the vapour
dissapears. when you see the vapour is at very high g's, meaning very high

this high g condition for a second or so, and then reduces g's and the

As i said camber can make lift at zero aoa, but not a ton. wings have
thickness for structural reasons and they have the shape they have to get
the most lift for the least drag. dont get me started on drag now! so
cambered wings are better then flat wings, they make more lift cause they
throw air down better.

this is the time honered aproach and it works ok. but stall speed is a
function of g's, cg location, weight, and power on versus power off. if you
can remember all those stall speeds and know which one to remember to give
you the maximum amount of lift in a criticle situation thats great. Stall
angle is constant. no matter the loading g's cg, power on power off weight.
AOA at stall is the same. so if you want simple that is simple. stall
speed is the complicated one. if you always fly 10 mph above your worst
case stall speed you wont stall, but you wont be making very near best lift
in lots of situations, and if you are trying to clear that tree to the
emergency landing field it would be nice to use all of your lift and know
you arnt going to stall. Your a way better pilot then I will ever be so
please fly how you like, but consider that us hacks might be able to fly
alot safer if we have a maximum lift indicator that is easy to use.

I was talking about a flat plate there. The bottem surface of a thick
airfoil is not where we measure AOA. AOA is measured from the tip of the
nose to the tip of the tail, and when the bottem is parallel to the air flow
you still have positive AOA.
Again camber alone can make a bit of lift but it isnt much. without aoa
your not going to make very useful flying machines

Maybe. For a long time I had my wings folded when the plane was in the
hangar and to move it around the only way to do it was to grab the tips and
pick them up and push the plane around like a wheel barrow. Folding the
wings back puts quite a bit of weight on the tailwheel and when you pick up
the back end that way all that weight is placed on the connections that join
the curving tip tube to the leading and trailing edge. It just seemed to me
like more than the system was designed for. I did the extra reinforcement on
the tip but don't know whether it has saved me anything. However, my
wingtips are nice and rigid after quite a bit of horsing them around.

If you are going to trailer and fold often, put them in.
One of the things that comes up when trailering is the proper support of
the weight of the wings, near the tail when folded. The tail can't support
the full weight of the wings, it is too much for the tailwheel spring. So
you must support the boom tube back there, or the wings as I did on my
trailer. I added a couple boat rollers, which the wings' leading edges
roll into as they load onto the trailer. The rollers are located so the
part of the wings' leading edge tube that rest on them is right at the
most-outboard full rib. That is where the plans show to add the angle
aluminum. In hindsight, I wish I would have doubled up on the gussets at
this location too (one on each side), to further reinforce. It is tough to
plan for something you don't know about yet.
Trailering and handling has been a lot more stressful than flight (for both
me and the Kolb).

You can save wear and tear on the wing tips when lifting the folded plane
by opening up the ends of the trailing edge spars and inserting 2 1 ft
pieces of 1" tubing in the ends whenever you need to pick up the folded back
end. no stress on the wing tip or fabric. Remove before flight.

John, I fold and unfold my wings every time I fly this 13 year old
FireStar. The 1/4" bracing broke after about 50 hours where it met the
spar (sharp angle in that spot). If any of you guys hear anything
rattling around in there, it's probably that 1/4" tube. The new models do
not have it, I don't think. I had to cut a large rectangular piece out of
the fabric to replace it with 5/16" tubing. I also beefed up the area
with some more 3/8" tube to reinforce it. I never found out about this
angle brace until now.
While I'm on the subject of wing folding, I have a very nice cradle the
fuse tube sits on while the FireStar is stored. The cradle is welded to a
vertical stand then to an axle with wheels. It keeps the weight off the
wings and tailwheel when stored.

Better check where you placed the counterweights. If you installed them on
the rear spar they may not be as effective as you may wish :) A better
location would be the leading edge of the aileron.

if what you are looking for is to get over the top of a tree

maximum angle of clime. not to be confused with the maximum
rate of climb.
to find a maximum angle of climb do several test runs at 5
mph incriments starting with a gps and travel 1 mile noting
the altitude at the begining and end of the mile.. the
speed which gives you the best altitude difference would be
the best angle of climb. for the best rate of climb
set it up about the same but climb 1000 ft at different
speeds and see which speed gives you the shortest
time. in setting up both test start the climb about
500 ft befor the test ru;n begins so that airspeen and angle

Everything ive ever seen on this subject is that boats make best speed going
somewhat into the wind. Close hauled is probably overstating it but ther is
an angle to windward that is faster then andy other direction. I have been
searching the web for a reliable source on this one bu have not found one
yet. I'll let you know if i do.

only when they are making lift. the trailing edge curves up to provide
pitch trim in a flying wing. the wing is still at an angle of attack to
make lift. For those who refuse to believe that lift is made by throwing
air down i give up. I have done my best to explain and it apparently hasnt
been good enough. I knew I should have left this one alone! back to lurk

Speaking of vapor, several years ago, I took a picture of a USCG C-130 on a
short field take-off from Port Angeles, WA. ( CLM ) Plane was silhouetted
against the trees on an overcast day, and you can see the vapor trails from
the prop tips on all 4 engines. Looks like a basket weave over the wings.
Lest anyone think I'm bragging about the great skill involved, I was trying
for a pic of the plane breaking ground. A buddy's girlfriend looked at the
print and asked what those lines over the wings were. Blew us all away. If
anyone's interested, I'll scan it in and email it to you direct.

since I have done a lot of sailing, I can attest that a broad reach is the fastest
angle for a sailboat. I think the simplest explanation that can be given
is that on a broad reach, you get the full force of the wind plus the additional
aerodynamics of the sail trimmed for the apparent wind. Both forces added
is the maximum power for sailing.
It interesting to note in ice sailing, because there is very little friction, an
ice ship can sail at two or three times the speed of the wind. Once speed is
developed, the sail is then trimmed for the apparant wind instead of the true
wind.

Okay, I have had enough. All you smart guys out there that seem to
understand the theory of stalls better remember one thing for sure. No
matter what you have for guages, guides, gps, etc, one thing prevails and
that is your butt. You had better just watch what the hell you are doing and
what the plane's attitude is. My big question to all is: If you cant or
dont watch the ASI what makes you think you are going to watch a stall meter
or even hear it for that matter. I practice on NOT stalling. Once you have
stalled while low, it is too late. I really dont understand why you cannot
just feel the difference. I fly many different types and I sure can. Maybe
its just me. Mine fits me like a shoe and I love my little '86 Firestar.

Ted,
I think that for those pilots that fly the same Kolb regularly, stalls may
not be a problem. But for someone who is either not current of changing planes,
it is a real problem. Then there is the pilot who is not current and flying a
different plane for the first time.
I even had an adjustment to make when I changed from an original Firestar to
a Firestar II. Then after a winter of rarely flying, I went back to expecting it
to be like the original, and had to make the adjustment again. The Firestar II
needs a little more power in flair and stalls at a higher ASI. Easy to forget
when everything else feels the same.

Hi John and listers.
I did install these angles on the outboard rib, just in case, but another thing
I should have done is make the handle bar inside the wing end tube, for easy
handling when folding. Someone on the list did just that, but I can not remember
who it was.
It looks rally nice and makes it much easier to handle the wings.
I am sure this member can give you more information.

Gentlemen:
I just had a conversation with Kerry Yunck, the top Rotax maintenance guy
at Lockwood Aviation which I think might be of interest to Kolbers running
the 582. The background to the conversation is this: I try to be pretty
scrupulous about running my motor just like the books says. The 582 repair
manual says to run 50/50 antifreeze with distilled water, which is what I
have done. However, the other day I was looking at the clear plastic line
into my overflow bottle and was distressed to see some white sandy looking
precipitate at the bottom of the loop.
Everyone running the 582 knows about the reported problems with cross
shaft leakage, and grit in that system is what is supposed to cause the
problem due to abrasion on the seal. So I promptly called up Kerry and he
reports that he sees about 50 582s per year, and the vast majority of cross
shaft leaking problems come from guys that have used tap water to mix their
coolant.
However there have been some reported problems even when the operator was
using distilled. This drove the engineers in Austria nuts for a while
because there were virtually no reported cross shaft leakage problems in
Europe, until someone realized that virtually all antifreeze in Europe is
phosphate/silicate free while the US is still using phosphates and silicates
in antifreeze, apparently as some sort of blending agent. Kerry reports that
if you are using regular aluminum compatible antifreeze and distilled water
per the manual you can still precipitate out enough grit to buy yourself a
problem. This is obviously what the white stuff is in the bottom of my
overflow line.
Lockwood is recommending Havoline extended life antifreeze. It's orange.
I know there was a thread on this subject a while back, and I bought some
silicate free antifreeze, thinking I'd switch when I got around to it. You
can bet I'll be swapping the old stuff out pretty soon now.

Topher,
I found it ironic and interesting that the most basic issue to flying
generated such a long thread, 97 years after Oroville and Wilbur
figured it out, and long after most of us have piloted a plane. I think
most people on the list appreciated your simplified explanations,
including myself. There will always be a portion on any list that
thinks any subject is beat to death somewhere between 1 and 100
messages on that thread. So, don't lurk if something needs to be said.
Maybe next we could discuss the cause of something else controversial,
like the cause of gravity. NO!!!!!!
Happy wind deflecting to ya. :)

Topher, sure but I'm not that dense. The reflexed trailing edge of the
Kasperwing, or any reflexed wing, deflects air upwards due to it's
reflex. So how can the downward wind theory work here?

Hello Kolber's,
I would like to thank everybody for the many responses on the outboard
rib reinforcement. Ya'll made the decision easy. I didn't need much of a
excuse to call Sue at the New Kolb Co. Kind of got carried away after I
started talking to her---think I spent about $500. Oh yea, we laughed
talking about some of Big Lar's antics too.
On a more serious note, I have some more questions. I've heard people
call theirselves butchers and so forth on this list but I beleave I have got
everbody beat. Take today for instance. I have all the tail feathers and
wings and so forth built and was assembling the plane so I could align the
aileron horns and counter balances. After getting this done I figured I
would fold the wings just to look things over and see where the wing fold
tube will fit in the fusalage tube. Well the wings didn't want to fold all
the way up next to the tail feathers. Upon closer inspection I could see
that the steel inboard rib was binding against the lock nut on the universal
joint. I turned the bolt around in the universal joint since the head
doesn't protrude as much, but it still rubbed. Here's where I really got
stupid. I decided to grind a little bit of the bolt head off and to grind a
small notch in the steel inboard rib with my dremal tool. Well I wound up
with a hole in the bottom steel inboard rib just below where the drag strut
fitting is welded to the steel rib. Does this part of the rib see much
force? I don't know exactly what to do. Also after grinding the main spar
tab per the plans so that it don't bind with the wing tip on the ground I
have about 3/16" of metal from the edge of the main spar pin hole. Does this
sound right. Sorry for the long post but I need some advice on what to do.
Thanks.

think of an s shaped duct. takes air in at the top of the s. brings it
down to the bottom of the s. throws it out the back with a bit of upward
motion. still the overall effect of the s duct is to bring the air down a
bunch, even if at the end it gives it a tiny kick up. That website is
really good by the way (not just cause it backs me up completely!) give it
a read if your still interested.

Uh Oh ! ! ! I think I represent that remark. What price fame ??? I hope
you were laughing 'with,' and not 'at.' Paranoid Lar.
On a more serious note, John, I seem to remember a similar problem on
Vamoose, but it's been so long that I'll have to go out in the morning and
take a look. Gonna have to finish this tarnation thing one of these years.
Seems like the fittings were longer one way than the other or something.
Switched things around till they fit. Hang in there till the A.M.
Problem I've run into, and haven't yet cured is the lexan section between
the wings. ( Gap seal ?? ) When I fold the ( as yet un-covered ) wings,
the trailing edges contact the gap seal and bend it way up. Looks like
surgery is a necessity, cause the fabric will certainly not stand that.
While on lexan, I've mentioned before that I'm copying Ron Christensen of Mk
III 1/2 fame, and mounting that gap seal permanently. More ( ! ! ! )
problems. Lot's of them, of which one of the main ones was bending a 2'
long strip of lexan 90 degrees. Tried clamping it between the edges of 2
sheets of plywood, heating it with a heat gun, and putting all the force I
could with heavily gloved hands. Did a real good job of messing up a
perfectly good piece of lexan. That stuff is Tough ! ! ! Tried bending a
small scrap a tight 90 in the vice with a hammer, like it was metal, and it
worked fine. So, with the new sheet marked out, I took it to a sheet metal
shop, and had them bend it on the brake. Perfection, with no effort, and it
only cost $5.00. Big Lar.
P.S. Ron's plane was a real inspiration. What a beautiful job ! ! ! I
copied several of his ideas.

Lexan is the right material. It is almost unbreakable. Plexi glass will

I have a little bit of trouble with ignition noise from my 582 getting
into my Yasu handheld radio. I recently got a recommendation to go with
BR8ES plugs as opposed to B8ES plugs which I have been running up until now.
Is there any downside to making this switch? I understand that there is also
a resistor plug cap available from Rotax. What are the trade offs associated
with using both the resistor plug and the resistor cap?

I use both and have no problems. As I understand it there are two types of
resistor caps. If you use resistor plugs then you should use the lower value
of resistor cap. Don't recall the values but I'm sure you'll get them from
the list.

Not to supposed to use both, at the same time. However they used to have a
metal splark plug cap that does the same thing, but doesn't cut down the
spark, or voltage, or whatever the normal resistor caps do-it just acts
like a shield. Proabably it might be a good idea to shield your wires with
the slide on "mesh" and ground it to the engine if you havn't already done so.

I found Velcro in 1" & 2" wide with adhesive already on it. Available in
black & white.
I used 2" on the wing [put it anywhere the gapseal is likely to rub] and 1"
on the gapseal. If you are going to remove the gapseal often then you could
pop rivet the velcro on the ends to the gapseal.
Speaking of Lexan Gapseal- I am only 6' 0" tall, but with my Comtronics
helmet on, it vibrated up against the gapseal [noise]. Remedy- I got a big
clear plastic bowl from Wal-mart about 12" in Diameter, cut a 11 1/2" Dia.
hole in gapseal [next to aluminum leading edge], and pop-riveted the bowl
up-side down inside the gapseal. Use aliminum pop-rivets with the big heads
& backing plates to minimize cracking of the Lexan & plastic.

Randy,
My fabric gap seal gave out last spring and I was forced to make one out
of lexan for my Original FireStar. There are plans for this, contact Kolb
to get this and the formed aluminum LE piece. I used the sticky-backed
velcro to attach it. I also installed a couple of small eye bolts to the
bottom of the lexan (just ahead of the engine) and found a mini-bungee to
hook into the eye bolts wrapped around the main tube. Move the bungee aft
once it's in place. I didn't want to trust the velcro to hold the lexan
down in the rear.

John,
Since replacing the inboard rib would be a monumental task, I would
consult an A & P type about welding a sleeve reinforcement over the area
where you weakened the rib.
On my Mark III I had a problem with the wings not being free to fold
inward due to an incorrect dimension on the inside section of the
universal. Kolb replaced them with the correct part.

Subject: | Baggage Compartment |
Dear Kolbers -
I am thinking of installing a modest cargo sling in the aft area of the
fuselage pod in my Mark-III. I have a couple of questions that I'm
hoping the collective experience of this List may help me answer:
I'm planning to install this cargo sling in the area immediately aft of
the fuel tanks. Ample room while still keeping stuff off the aileron
torque tube. Instructions say to fabric cover over the top of this
area. I see sufficient volume there to install a simple net or webbing
sling, maybe large enough for a couple of small duffle bags. I have
seen a few pictures of Kolbs that have used this empty volume for cargo
carrying (Cliff Stripling's hinged-top box comes to mind).
1) Will this cause some sort of dangerous disruption of airflow (i.e.,
overpressure in the aft inside area) if flown with the doors removed and
this spot left open? (I remember the stories from some years ago of a
few CGS Hawks loosing aerodynamic controllability when flown with doors
removed!)
If nobody convinces me that this is a bad idea, I think I'd like to use
nylon webbing for this purpose. You've seen it: inch-wide nylon strips
sewn together in a grid, three inches between stips, like the troop seat
backs in C-130s and such.
2) Anybody know where I can get this kind of webbing?
Any advice will be helpful. Thanks -

I think you will be fine for airflow, but keep an eye on your CG, if you are
putting significant weight way back there you could get into an aft cg
situation.

The instructions that come with the clear plastic cover that goes behind
your head and is held on with velcro, say to remove that cover if you're
going to fly with the doors off. Otherwise the air pressure will blow it
out and back into the prop. If you follow the plans, and cover the area
behind the seats and tanks, and mount your baggage holder below that cover,
you shouldn't have any problem. For webbing, a Wal-mart or K-mart should
have something sufficient, like lawn chair webbing or some such. If you
want the real good stuff, go to a sporting goods store, and get the
mountaineers sling webbing. Kinda over-kill............... Then
again, maybe you could get seat belt webbing for next to nothing from a
wrecking yard. A friend in Port Angeles who built a Capella put a sling
behind the seats, and adapted a small hikers' day pack to hang on it.
Things didn't fall out, and it served double duty. Handy ! ! !
We'll talk to my........uh........buddies.........about rust a little later.

Hey Kolbers,
Thanks Big Lar, Richard and Ray for the responses and advice. I will
probably get one of the boys down at South Mississippi Light Aircraft to
take a look and make some kind of weld repair. I thought about replacing the
whole inboard rib, but that seems like overkill and a lot of rivet removing
that I don't like doing. I will definitely do something as I'm not
comfortable with it like it is. I'm still not sure why I had this contact
between the two points. I did seat the drag strut end fittings a little
deeper than the plans call for (1/16~1/8") but not enough to cause the
amount of interference I'm getting. I will check with TNK and see if there
is a different universal joint I can use. If I extend the drag strut fitting
out more then I will also have to weld a new tab on the steel rib where it
pins at the front of the cage in order to make the wings align across the
trailing edge. Am I missing something here. Maybe I'm making it harder than
it should be. How about Dennis Souder. Maybe you could shed some light here

John,
Had a very similar experience on the right wing. I seated the drag strut
fitting too deep, but that was the position where the wings came into
alignment. Spent many hours using a water level, and with the help of a
neighbor who is a mason - builds 200 foot long walls straight and true - got
things lined up.
I have a slight dent in the bottom of the inboard rib because the first time
I folded them, it pinched the steel tube on the head of the bolt - I didn't
even feel the contact happening.
My thought at the time was that if I changed the drag strut fitting, I would
have to rig again, including re drilling the main spar attach points, and
welding etc... I'm not planning to fold the wings much, so I'm not really
worried about it. If someone knows what I did wrong, I would love to hear
it - I've given up trying to figure it out.
After folding and unfolding the wings 5 or 6 times, it seems to me that it's
kind of precarious to have your plane in the folded state. I'm not saying
it's a bad folding design, just that the plane is naturally stable with the
wing struts etc... in place.

Subject: | Re: Outboard rib reinforcement |
Hi Chirs and Kolbers,
Sounds like you experienced exactly what I'm going through except that I
will be folding my wings quite regular. I just got through talking to the
TNK and they are sending me a universal joint to compare to mine. They said
some of the earlier model kits got shipped with universal joints that had
the hole drilled in the center of the outboard (part b) universal joint
piece. This hole (the hole that attaches to the inboard universal piece) is
supposed to be offset which will provide clearance in the place that I need
it. The hole in mine is not centered but it is not offset much either so I
will keep ya'll posted on the outcome. In the meantime I'm just going to get
South Ms Light Aircraft to weld up my steel rib. New ones are about 125
dollars apiece, not to mention the aggravation of taking the old one off and
installing the new one.
Later,

Subject: | Pre-coat of Poly-brush or Poly-tak |
Listers,
I am getting ready to start covering my elevators. I have watched the video
and read the Stits manual and the Kolb manual. I am not sure which one to
follow.
The Stits manual specifies pre-coating glue areas with 2 coats of thinned
poly-brush.
The Kolb Manual specifies pre-coating glue edges with a thin coat of poly-tak.
The covering video does not mention anything about a pre-coat.
I am thinking that the Stits manual is working on the basis of heavier,
faster, and "certified" aircraft for its recommendation of 2 pre-coats of
thinned Poly-brush. This is probably not a big deal to most of you. This is
my first time with fabric covering and I am a little (make that a lot) unsure
of myself.
Any help the list would be appreciated. If you read this in the next few
days - sorry you couldn't go to Sun-n-Fun like me. I'd call Jim & Dondi but

Subject: | I Finally got my Kolb |
Hi gang,
Well I'm no longer in lurker status. After months of selling the old Cobra
and looking for a Firestar II, I finally bought one. It's ready to go with
about 250 hours on the airframe. Now I have a couple of questions.
1) I plan to register it as experimental so I can legally take up
passengers. I'm concerned that the airworthiness inspection is going to be
tough since I don't have the contruction log or pictures from before the
wings were covered. Has anyone else out there certified someone elses
handy-work? How did the inspection go?
2) I didn't get the operating handbook or any instructions either. Does
any one have a weight and balance sheet for the Firestar II (wing and wheel
positions, allowable cg range, pilot, passenger, fuel positions etc.) I
plan to get all the data later I just want enough to get flying in a week or
two. I guess a spread sheet would be the easiest format.
3) a good first cut at Vx and Vy would be nice too. I plan to go find my Vs
on the first flight (I'm assuming about 30-35 mph stall).
Thanks for the help and for all the tips I've soaked up so far.

Subject: | Mk III Tailwheel |
Hi Peter,
I had the same problem as you have anticipated. At the airport I use I
have to taxi about 1.5 miles from the hanger to the runway threshold
on concrete taxiways. The standard narrow wheel with a cantilevered
axle (giving a slight tilt to the wheel) caused the tire to wear out
every 3 to 4 months. I tried the shopping cart type (plastic wheel
with solid tire) but the hub disintegrated after 6 flights.
I then decided to make my own design. This design is exactly like the
Kolb tailwheel but there are 2 down tubes welded to the cross tube
with the wheel mounted between them. The axle is mounted on the ends
of the 2 down tubes in the same way as on a bicycle. For the wheel I
used the solid tire from an industrial trolley wheel (5 inches
diameter by 1 inch wide), but made a split aluminum hub using the same
bearing as Kolb . This arrangement has now lasted for 2 years and the
tire is about half worn - a replacement tire costs about $5. The whole
assembly is about half a pound heavier than the standard assembly. I
can send a sketch of the design if it would be of use, but you would
need to adapt it to use components available in the US. Please e-mail
me direct if this would be of any use.

Peter -
I installed an aftermarket replacement for my Mark-III Tailwheel.
It looks almost exactly like the one that comes from Kolb, with the
exception that it is one inch wide (instead of a half), and is 4 inches
in diameter instead of 5. Same hard plastic core, pressed bearings and
hard rubber outer as the original. The center is offset slightly, so it
still fits on the original half-inch diam axle.
I found this at a caster shop, here in town.
Cost was $11.
Take your tailwheel axle assembly to your local caster shop and try to
find the one that will work. If you cannot find one, let me know and
I'll try to dig up the make/model/serial number for you.

Subject: Kolb-List: gap seal
fand what did you use to glue the velcro. Also looking for
any good tips on bending to fit wing. Thanks Randy
Randy, I did not use velcro to attach my gap seal. Wanted something
alittle more secure.I used cam-loc's. I used the "soft" side of the
velcro, just to protect the wing fabric from wear. If you look at the gap
seal from the side, it looks something like the letter "D". The right
side of the D is made out of .0010" aluminum, it has a cam- loc that
locks into the leading edge of both the right and left wing. The top and
bottom of the D is made of lexan, rivoted to the aluminum. At the top
back of the D, I rivoted an angle piece of aluminum, across the seal.
The vertical portion of the D is lexan, also rivoted to the aluminum.
The bottom rear, also has a piece of aluminum angle rivoted to the
vertical lexan, but it is cam-loc'ed to the bottom piece of lexan.
So when I put on my gap seal I spread it open over the main spar carry
through. Then cam loc it together, plus cam loc it at the leading edge.
It will not come off.
Hope this explanation helps
I'm not good at explaining, so if you have any questions, call me at

Subject: | The RG battery has come to WalMart . . . |
As I was passing by the automotive battery rack in my
local WalMart yesterday, a particular product caught
my eye . . . it was a fairly heafty battery with the
grain-elevator like collection of cylindrical cell
housings.
I picked up a flyer on what is called the EverStart
Ultra, a totally sealed, jelly-roll style construction
RG battery. This is a big beast. I would guess it
to be between 25 and 35 a.h. in capacity. Can't
recommend this battery for many airplane applications.
The noteworthy points of this find are (1) RG technology
has found it's way into the most rudimentary of consumer
product streams and (2) the thing sells for $75. The
next thing to watch for is a line of smaller batteries
with the same technology for use in garden equipment
and perhaps even motorcycles.
Of course we don't know who makes this particular battery
for WalMart . . . it has the look and feel of an Optima
but given the age of the original patents by Gates
Energy Products on the Cyclon series jelly-roll cells,
this battery could be made by anybody. Only a test
in the marketplace will tell us if this battery is
worth the lead and plastic that holds it together.
It's not here yet but I believe it's a matter of time
before you can buy a better airplane battery from your
local WalMart than you can buy from any FBO . . .

Get something simple, like a stick of wood that holds them down, something

You want an idiot proof parking brake system, otherwise it may not entirely
release when you think it has, and then may still be on when you touch down
at your next landing. (Guess how I know that?) (No, it wasn't the MKIII)

Someone asked:
> is there a parking brake setup for the Matco hydraulic heel brakes? <
Adding a parking brake to a hydraulic system is as easy as installing one
more valve. Matco sells one for about a hundred bucks, but really doesn't
need to be elaborate to work. You want a valve to close after you push the
brakes to the floor, thereby trapping the pressure between the valve and
the wheel cylinder. I guess you'd need two of them, if you're using
individual wheel brakes. I wonder if the $8 ball-valves they sell for fuel
shutoffs would work. They are 1/4", they are brass, they are cheap. I am
guessing we're putting less than 150 psi into the brake lines.

The new VW Trends magazine for May 2000, page 26, has a tech report on a

www.aircooled.net This is a high temp coating for exhausts, etc. that can
be applied at home. Looks good, and I don't remember if anyone mentioned it
on the string a few months ago. The ad also touts it as an anti-corrosive
coating for battery mounts, etc. Kinda reminds me of the "Hammerite" paint
I used on boat trailers. Stuff was amazing. Anyway, a quick look at the
sites tells me that the -15 is a medium temp anti-corrosive coating, and
the -20 is the hi-temp stuff. Go to the aircooled.net site and enter POR-20
in the search box. Looks like a good product. Also, for anyone
interested in older VW's, and /or VW engines and parts, the aircooled.net

I don't know much of anything about the other radios, but I do have a
DelComm and know a little about it. It is a fine quality radio --
excellent transmission and reception. They are cheaper than the
others. The compromises, i believe, include:
-bigger size -- not horrible, but size matters
-they do not work with most mic's. I forget the details on this, but
they require a different impedence mic than is standard. UltraCom
helmets have this and an old David Clark style headset have it. Sorry
this is so vague off the top of my head. There is an expert source of
information, parts/kits, and help (for reasonable fee) wrt Delcomms.
It is Jim Vroom in Dallas. He helped me put together a great

Randy, that tube extention is real handy when you're putting the wing into
position from being folded when the full enclosure is in place.Howard is
right, it also supports the leading edge of the fabric gap seal. G.Aman FS2

I found it positively in the way when putting up the wings, but that is
on a FS KXP. I think the tubes bumped into the KXP's long windscreen.
I've also used a lexan gap seal so didn't need the tube support for the
standard fabric gap seal.

On my Firestar, Mk III and FireFly, I whacked those tubes off after almost
poking a hole in the fuselage fabric while folding the wings. Attempted to
use the soft wing gap cover but went for .016, 6061-T6 Al. on all three. I'm
sure it's all up to personal preference. The two piece metal wing gap is some
extra work (especially the cutting of the parachute exit hole) but I think it
looks better and probably adds a tad of lift.

Hi Randy and Kolbers,
On the Twinstar Mark II that I had the leading edge extensions helped
support the alum. gap seal but I think the most important function for that
particular plane was that it gave you a place to secure the inboard end of
the wings while hauling it on a open trailer. I used rubber bungy cords to
strap the wings together which made them secure on that end of the wings.
Also put foam pads between the wings and cage where the wings would make
contact.
Later,

Although I have done no difinetive experimentation to verify this, I believe
the VG's help all aspects of your plane's performance. As far as fuel burn
is concerned, I burn the same amount as my wingman who flies a FS I & who's
gross is 150 lbs under mine, this was not true before I installed the VG's.
Also, we both maintain level flight at same engine rpm. As far as cruise, I
just don't know. I like to run about 60, even though I can go 90 at full
throttle.
Possible additional uses :
Under Horizontal Stab. to increase elevator authority
Both sides of Vertical Stab increase rudder authority
Both side of Cage for improved airflow to the prop.
I intend to try all of these [time permitting]. Let me know your results.

Question: It's pretty well known and accepted that ultra-violet light
will quickly destroy the dacron fabric that we cover our planes with.
I've been wrapping the completed ( ! ! ! ) tail pieces with a blue surgical
sheet ( that's what I have available ) to keep them clean and protected
while I do more pieces. My only storage place is on the porch where the
work is being done. Looking at them today, it dawned on me that the coating
instructions call for silver paint until no light can be seen through the
fabric - 2 or 3 coats. When I look thru the blue sheet, it is NOT dark.
Light coming thru is blue. Blue. Hmmm...............seems to me that the
blue cloth would filter out, or slow down the U/V ( change the wave length )
to where it won't harm the fabric. Then again..............maybe not.
They are only in the direct sun for a few hours in the morning, till the sun
gets above the roof, and haven't been out there too long. What are you
guys' feelings about this ?? Should I work out some kind of solid shield ??
Will the blue sheets be OK ?? They aren't regular woven sheets, but some
kind of pressed synthetic that is water resistant. The more I think about
this, the un-easier I'm getting. Big Lar.

My plane is a Firestar (1985) so possibly is suffering from old age.

HI Lar
If your porch is glassed in I do not think the UV rays will penetrate.
Glass lets in light but no UV. Years ago I did an experiment and nailed a
chunk of bare fabric to a fence post and let it stay there. after a year it
seemed more pliable but just as strong. I did not have any kind of fabric
tester but it seemed strong enough. I will also repeat my old tale of the
Vector sitting outside for 8 years with no protection other than house paint
on the wings. Still good when I tore it apart. The contact cement holding
the fabric on seemed to hold better than any polytacked fabric I have ever
pulled off. When I do my Mk111 (or maybe I will call it the MK X) I will
omit the silver paint. Reasoning that I will hanger my bird most of the time
and the new synthetics are more resistant to UV than the old cotton
coverings of years ago.
Bet I just gave Jim or Dondi a heart attack.
Woodi
I believe a silver coat can be brushed on and the fabric will suck it in
and get rid of any brush marks. That is how it is done with the HI PEC system.

Yesterday I started installing some of the hardware purchased at Sun 'n Fun.
Replaced all of the fuel lines (1/4 and 1/8 ), the squeeze pump and filter.
After a close QC inspection by Rut Fuller (remember him?) I rolled her out to
make sure the engine was ready to fly. Switch-on, squeeze the bulb till the
carb bowl, new filter and lines were full. Two strokes on the prime pump,
yelled "clear !" and pulled the starter handle. She would not even pop. Gave
the prime pump a few more stokes and tried again without success. Checked the
rear plug and found it bone dry. When I went over the fuel system again I
found that the 1/8 lines to the primer pump were switched. It was trying to
pump fuel back into the tank from the carburetor prime port. Switched the
lines and made sure the flow was correct. Pulled the starter maybe a dozen
more times then gave up and pushed her back in the hangar. Re-checked the
plug and it was still dry. Finally checked the carburetor bowl and as I
released the bowl it was jamb full and fuel came gushing out of the bowl
under pressure. I was running late by then and had to leave.
The purpose of all this is to see if anyone else has run into this situation
or has suggestions on what to try next. Constructive help always welcome.
Thanks in advance, I'll post my results when I solve the problem.

Glass will allow UV. I have a perfect example
In the screenprinting industry we use an exposure system to burn our
screens. The emulsions are only sensitive to UV. The film is placed
under a glass and vacuum is activated. Exposure is thru the glass in
about 1 minute. The glass does not block UV. I also use UV activated
adhesives to bond glass. A small blacklight is all it takes to activate
these products thru 1/2" smoked glass.
On the other topic. If you must use the Stits process just to feel
better go ahead and use the whole batch of materials.
I have done my own testing of fabrics and coatings and find that
ordinary Polyurethanes like Red Devil or Krylon bond very well to Stits
fabric and showed no sign of degradation after many months of exposure
to Southern California summer sun.. I would only use these alternate
coatings on an ultralight where the speeds and loads are lower and the
resale value is so low as to be a non-issue. You will certainly save
money on the coatings and you will not have to breathe the noxious MEK
fumes.
Still should use Polytack to hold the fabric on as it is just as easy.

OK, for what it's worth, my understanding has always been this: U/V will
penetrate glass, but in so doing it's slowed down (??) to infra-red
frequencies, which will not penetrate glass, and reflect back as heat. This
is why a closed car gets so hot on a sunny day. (Especially my
big-windowed, dark green T-Bird in the desert) So, on that premise, is the
blue fabric eliminating the U/V on my tail feathers, or enhancing it ?? Or
will it make any difference ?? I think, just for my own peace of mind,
that I'm going to cut a chunk of plywood to cover them, and hide them behind
it. I'm not sure how that translates to curing adhesives thru glass with
U/V light, cause I've seen that work too, and I know you're right. That's
the main factor in my deciding to really cover the fabric, and not take a
chance. As far as the further coatings go, I'm pretty well committed to the
full Poly-Fiber system. I should be able to fly for at least 10, and maybe
as many as 15 more years, health and physical systems permitting, and if
properly done and cared for, the fabric should last that long - even here in
Palm Springs summers. Wish I could talk Dad into leaving this awful place,
but Mother's buried here, so that's the end of that.

Bob and Kolbers:
I don't want to seem argumentive, but I have yet to see a
Rotax or Cuyuna powered UL with reduction drive windmill.
The prop stops when the engine stops. I'm sure a lot of us
would have liked to see that ole prop windmill when we lost
an eng on final so we could get an air restart. One
exception, that I have no experience with, is the "clutch"
that some people install on their drives that allows the
engine to idle with no prop load. I can see that system
allowing the prop to windmill should the engine shut down
completely or at idle.
I also find just the opposite true of your comment reference
drag and a stopped prop. A stopped prop has far less drag
than the disc created by a slowly turning prop at engine
idle. Of course, I am speaking of Kolb aircraft. Do not
have enough experience to comment on "real airplanes." On
our airplanes, glide is increased a great deal after the
prop stops. I feel it is a good idea to learn to do engine
off practice emergency landings for just that reason. Most
folks do practice eng out emergency landings at engine
idle. Get accustomed to that mode. Then when the engine
actually stops, they are surprised to find the aircraft
flies and glides much better, which could possibly cause
them to overfly their intended forced landing area.
Correct me if I am wrong, but this is the way it works with
all the Kolb aircraft I have flown.

Bill and Kolb Gang:
Yep! We got the Fire Fly flying, after doing some head
scratching and adjusting to get the brakes to cooperate.
A new type of mechanical brake was installed with a little
longer gear legs prior to departure from the Kolb Factory.
Norm Labhart test flew the FF at Chesnut Knolls and it
worked ok. I flew it a little the first Sunday of S&F and
had some problems with the brakes. Got to have good brakes
to ground handle the aircraft in all that traffic in the UL
area at Lakeland.
Before the week was out, both Norm and Bruce Chesnut were
flying the FF.
The Kolb Company had a ball at Lakeland this year. Dick
Rahill came down to fly the Firestar, as usual. I flew the
SS. Norm flew the MK III Extra most of the time. We had a
lot of wind, mostly 90 deg cross winds, but the Kolb handled
the wind plus natural and aircraft induced turbulence as
normal. There were many times when Kolbs dominated the UL
pattern. Friday evening there were all four Factory Kolbs
in the pattern and no other aircraft in the air for more
than 15 minutes.
I thoroughly enjoyed flying the SS this past week. Had a
chance to fly it fast, slow, and hard. It always did what I
asked it to do without any complaints. That includes some
severe landing gear testing, if you know what I mean. There
were times I was sure I had bent something. But to my
surprise, the SS shot did not bend and kept coming back for
more. If I had to build another experimental, it would be a
hard choice to make between the MK III Extra and the SS.
Would not be hard to configure the SS to hold a 20 or 25 gal
fuel tank and still have enough room for my camping gear,
etc. With a 912S it would have a very decent cruise and
still be able to handle those little short, rough UL
strips. :-) Oh well, got to wear out the old MK III first.
Enjoyed meeting a lot of you all face to face after being
friends on the internet for a couple years. Always enjoy
seeing old friends that I usually only get to see down at
Lakeland or up at Oshkosh.
Got to get busy with the MK III and get her flying. Lots to
do now that I am back home. Only two and a half months til
time to head north to Alaska. My work is cut out for me.
Thanks to all of you who have helped me out with my "flight

Big Lar.
I'm sure you'll get a few responses about this and I'll add my ignorant
2-cents worth. I've just completed refurbishing a 1994 Firestar II and since
I have neither the equipment, facilities, nor talent to paint, I covered my
UL with heat-shrink polyester film for the color coat. In order to do this I
had to omit the UV coating from the usual Polyfiber covering process. Being
concerned that this omission would leave me with degraded fabric over a short
period of time, I made up test panels of my planned finishing while I was
refurbishing the other pre-covering parts of the Firestar. The colored panels
are on the roof of my shed and have been tested, so far, up to 180 hours of
sunlight exposure. Punch tests have been done by a local A&P mechanic using a
Seyboth (?) tester. The original start-date punch results were in the green
for all colors - white, red, blue, and yellow. Punch tests results after 180
hours showed only the tiniest lessening of strength, that is, the position in
the green range nearly approached the yellow. I plan to continue periodic
punch tests just to see if and when significant degradation occurs, but since
I keep my Firestar in a hangar, the 180-hour test reflects quite a few flying
years for me.
Hope this helps.

first trip into the overcast skies of Montana.
The first take off I tried climbing at 55mph and the aircraft did not
seem as if it were climbing like it should. Executed a go around and
used 60mph as the approach speed. Flew down to just a few feet off the
runway then slowly started reducing power until the mains smoothly
touched the asphalt then reduced power to idle and let her roll to a
stop (8000 feet of runway sure is nice).
Pondered the problem for awhile then added one more degree of pitch to
the prop to see if it made any difference in climb out.
Taxied back to runway and smoothly added power. Climb out wasn't much
different so used 50mph for climb and decided this was acceptable.
Continued climbing in the pattern until 6000 feet. At this point a
friend was in his Citabria waiting for me and came up along side and
checked out the aircraft from his point of view (which surprisingly was
right side up, he can't stand to fly straight and level very long) I was
informed everything looked A OK.
He asked me what my airspeed was and when I said I was showing 55mph he
laughed and said he was showing 83mph on his indicator (no wonder climb
out was poor).
Proceeded to do control checks and stall investigation. Controls were
comfortable throughout every check so slowed down to see if I could find
the stall speed. At 28mph (On my indicator) the aircraft stalled with
very little advanced warning then resumed flying just as quickly.
At this point my left hand was frozen numb from the air coming through
the bottom of the door. I have my throttle on the left side and my hand
is positioned right where the air comes in (Brrrrrr).
My ground crew told me that I needed to do some practice approaches at
altitude, NOT. I felt if I stayed up there any longer I wouldn't be able
to move my hand at all (it really wasn't that bad).
Descended into the pattern using 45mph (as indicated on my erroneous
indicator) as the approach speed and used a lot less runway then the
time before to settle the aircraft back down on mother earth ;-)
Now I need to fix the airspeed problem and fly, fly, fly !!!!!!!
Come on Big Lar you're missing out on something fun.
It's hard to believe that 20 months ago there was a pile of aluminum

Subject: | Polyester film covering - LONG post |
For Topher and others of you that may be interested I'll cover (no pun
intended) the details of how I applied model aircraft polyester heat-shrink
film to my Firestar II. Maybe a little background first - I fly with some
other Kolb folks, a few of which have BEAUTIFULLY painted finishes on their
aircraft. Since I have minimal paint equipment, no good place to paint, and
inadequate painting skills, I needed a means to have a respectably-finished
Firestar that would not receive finger-pointing and laughs at the times I
would be in the company of the good looking Kolbs.
From a little experience on my past Spitfire ultralight, I'd found that
heat-shrink covering could be applied to Poly-Fiber covering material. I'd
had a need to add new sails to my Spitfire and found the tail coverings to be
a poor fit. So I covered these surfaces with Poly-Fiber fabric being careful
not to shrink the covering too tight for the lightly-build tail structure.
The finishing was done using Great Plains Coverite's film. I'll omit more
details of this development and application since the routine I did on the
Firestar is much better. However, results of the Spitfire tail covering were
good and can be seen at: http://members.aol.com/ulflyer/spittail.jpg
Before I did any actual covering I made several 14" square test panels. These
were simply pieces of " steel conduit welded into a square structure and
Poly-Fiber covering applied. From these I tried several finishing methods in
order to check polyester film adhesion, shrinking and attachment results.
Most of this was done using combinations of Poly-Tack (full strength and
thinned), Poly-Brush (thinned and multiple coats) , and Balsarite in single
and multiple coats. The resulting routine gave film adhesion to the
Poly-Fiber such that the film would tear when it was peeled from the
Poly-Fiber. This result suited me. The final routine is to finish the
Poly-Fiber fabric with one coat of Poly-Brush, apply the polyester film right
after a second coat of Poly-Brush, shrinking the film with heat and pressure
onto the fabric.
There are a couple of critical points in getting a wrinkle-free covering and
great adhesion - First, the Poly-Fiber fabric MUST be shrunk at a higher
temperature than the shrinking temperature of the polyester film. Generally,
I shrunk the Poly-Fiber to at least 300 degrees. For the color coat I used
Top Flite's Econokote, which is a low-temperature polyester film covering,
and shrunk it at about 220 - 240 degrees. Second, the second coat of
Poly-Brush must NOT be completely dry when the polyester film is applied. I
suspect that the remaining solvents in the Poly-Brush assist in the
attachment to the adhesive on the polyester film. The polyester film will
still adhere to the Poly-Fiber fabric if the Poly-Brush has dried, but not to
the peel-tear state. Light iron pressure and/or hand pressure (over a rag)
with a heat gun during the shrinking process will assure smooth attachment.
Another concern was the lack of UV protection I would have since I had to
omit the silver coating in the usual Poly-Fiber process. I made a finished
panel using the white, red, blue, and yellow colors of my Firestar and had
0-hours exposure puncture tests done by a local A&P mechanic. This panel is
currently on the roof of my shed and has had 180-hour tests done with only
the tiniest measurable degradation (probably just a variation in the use of
the tester). I plan to continue the exposure and puncture testing but the
180-hour result is several years worth of my flying time.
For my Firestar a completed wing panel took 4 days - Poly-Fiber and finish
bottom in 9 hours (1st day); Poly-Fiber and finish the top in 9 hours (2nd
day); add color covering (4 colors) to bottom in 8 hours (3rd day); and add
color (4 colors) covering to top in 8 hours (4th day). Results can be seen
at: http://members.aol.com/ulflyer/FSwingbuild.jpg Cost of completed wing
covering and coloring was about $650 and could have been a lot less with
fewer colors. Materials came from our Kolb source, Jim & Dondi, and a local
hobby shop supplied the color covering. I don't have any number info for the
cage and tail areas but they were done similarly.
Here's what I did:
Cover the structure using the usual Poly-Fiber process. Stop after the first
coat of Polybrush. Nothing unusual here except I omitted the taping of edges.
Everything else was done per Kolb instructions. I may note some thanks to
whoever posted the squeeze bottle routine for Poly-Tack application 'cause it
saved me lots of time, messiness, and waste. The only difference that I used
was following the squeeze bottle with a small brush instead of my finger. A
two-coat application to the full perimeter and ribs of the wing took only a
few minutes.
The application of the polyester film is made following a second coat of
Poly-Brush over a limited area at a time. I found that during cool weather
work (about 50 degrees) I could cover three or four main rib sections at a
time. During warmer weather I cut that back to two panels at a time to assure
that the Poly-Brush was not completely dry. One word of caution about the
amount of "dry" - I mean that the Poly-Brush should be just dry to the touch
but not "hard". If the Poly-Brush is still wet ANY amount, when the polyester
film's glue side touches the Poly-Brush, it's STUCK - no positioning or
moving that piece around. Once the film is laying over the area I began
tacking the edges with a small iron. On the open flat areas of the wing I
heat-shrunk the film with a heat gun and pressed the film onto the Poly-Fiber
fabric using light hand pressure on an old tee-shirt. I worked across one
panel at a time 'til I reached the end of the wet Poly-Brush area. Then I
folded the film back over the finished area, applied Poly-Brush to the next
area, waited a few minutes for it to "dry", pulled the film over this next
area and did the attach and shrink routine. Finishing and shrinking around
the edges was done in the usual model-application methods - pull tight, heat,
and press with the iron.
The only area requiring a slightly different technique is the scalloped areas
between the leading edge upper ribs. Here I just positioned the film lightly
from rib-top to rib-top and, using the small hand iron, pressed the film down
from the rib top toward the next rib stopping about midway between ribs. Then
I reversed the direction from the next rib, again meeting about halfway
between the ribs. This worked best for me.
Whew - I'm worn out again just typing this routine. I hope this helps those
of you that may be interested in this covering routine. If you have
questions, just ask and I'll try to answer them. More photos of my
refurbished Firestar can be seen at: http://members.aol.com/ulflyer and
just click on some of the .jpg images there, e.g., FSrtfront.jpg,
FStail.jpg, and rear34.jpg. Several photos are some of my other past
ultralights and other fellow fliers but you can pick out the Kolbs from them.

Polyester film wouldn't stick to it very well and heat application seemed to
soften the silver coating. See complete write-up in other post. Current
polyester, no-silver trial panel has gone 180 hours with no measurable
degradation. I understand your concern, though. My original concerns are
going away.

THe polyester film might be a very good UV barrier by itself, I will see if
I can find this out.
the uv additive that can be put in the polyspray probably could be put in
poly brush without effecting your method. I am going to try this out on a
couple of test panels and see if I can do it, if jim and dondi will sell me
some uv additive
A couple of questions
is all of the white on the whole wing film? was the $650 for just the film
or for film and the stits products? what size, length width and thickness
of flim did you use? can you see the seams? would you do it again this way
even if painting were an easier option for you?
"The finishing was done using Great Plains Coverite's film... For the color
coat I used Top Flite's Econokote"
Was the Great Plains Coverite used as the white on the FS or only on the
Spitfire? is Econokote available in the white? is either one better,
worse, cheeper then the other?
Thanks for the writeup, you are doing the true meaning of experimental
aviation! trying new things.
One thing I want to try is using Tyvek none woven polyester sheet instead of
dacron (polyester) fabric covered in the plyester film. Tyvek is used as
house wrap and is very tough stuff that shrinks like all polyester. it
would probably not need to be polybrushed at all because it is airtight by
itself. it is available in 10 foot wide rolls so a whole wing could be done
with only a rear seam. have to do lots of testing on it before I could
trust it though.

Well... that "Russell" guy ain't worth two dead flys.
Hey.. I just heard you guys had the "best" looking Kolbs they ever was!

Peter & List,
They show the weight for the 1.0 liter 3 cylinder @ 148 lbs. - don't know if
that's wet or dry.
Horsepower is shown as 62 @ 5700 rpm - don't think you'll be running at that
rpm too often - 58 hp is probably closer to reality, but that's a guess
after talking to Raven. Jeron says the geo falls between the 582 & 532, but
with the supercharger (coming soon @ $1250) it will edge out the 582.
Performance @ takeoff will be less than 582, but cruise will be better -
four stroke vs. 2 stroke.
Cost depends...if they do everything, and ship you one out of the box it's
$5795. However, if you find your own engine - I'm working on one now for
about $450 - and do the modifications yourself, and find the lighter
starter, & alternator & computer, & harnesses - the total price should be
under 3.5k.
I've spoken with them & ordered a catalog ($60 - goes toward purchase). The
documentation/quality of the manual is outstanding - photos, complete
explanations etc... Geron says he's got a bunch "about ready to fly" on the
MIII.
Anybody out there installing or flying the geo on the MIII???

You must use a '93 or early '94 engine & most of these would be hi mileage,
so expect to rebuild. A good used engine will cost you around $500, but
rebuild parts seem kind of expensive. The redrive kit, including the dry
sump, was around $2900.
When you remove the engine from the car you also remove the wiring harness
[carefully]. If you are really interested in this you need to call Raven &

First, polyester is NOT a "very good" UV barrier. I spent almost my
entire working years with thin film (4 mils, 100 microns) polyester used
as a photographic film base. This material has an optical density of
about 0.06. Very little is blocked by the polyester.
Second, remember that on an airplane the polyester is not intended to be
the UV blocker, but rather the THING FROM WHICH THE UV MUST BE BLOCKED.
Any blocking the polyester does is as a result of absorbing the UV,
which in effect is what is destroying it.
On a number of occassions I have used scrap thin film polyester to cover
something outside, and found that it became brittle in a relatively
short time.

I agree that there is likely no reason why the UV absorber used as an
additive with the PolyFiber process could not be used in either
PolyBrush, PolySpray, or PolyTone even though the normal use is
intended to be in PolyTone. All three (as well as PolyTak are
fundamentally the same polymer with different additives to perform the
desired function. One should keep in mind that the use of this additive
is intended only as an ADDITION to the normal UV blocking of the
PolySpray, not as a replacement. It has been demonstrated that coatings
without the silver but with the additive in the PolyTone have only a
small percentage of the protection of the material with the silver
alone.

How are you going to attatch the Tyvek to the structure? Very few
things stick to bare polyester. With our photographic films there had
to be two separate layers applied during manufacture of the film base to
permit the photographic emulsions to stick. The only adhesion that one
gets with standard aircraft polyester covering systems is the physical
adhesion of the first coating(s) penetrating the weave and encapsulating
them.
I really advise great caution in these areas .

Epoxy will get a nice grip on polyester as will many urethanes. I'm sure
one could find an adhesive that would stick tyvek to a framework.
Possibly Cyanoacrylate woud work.
Tyvek is a spunbonded polyolefin. Not certain if this is a polyester per
se.

Gil and Kolbers:
Me too!!!
Steve Whitman and his wife paid the ultimate price for
mixing covering and coating processes.
The fabric covering and finishing process is essential for
flight. If it fails, the result is catastrophic. I for one
do not mix and match. I used Stitts (now Polyfibre)
exclusively through Polyspray (silver). Primarily Aerothane
finish paint, but at times have used some Randolph finish
paints. Polytak and Polybrush hold the dacron together.
Polyspray protects it from UV, the one thing that it does
not like and that will destroy it.
Please use caution when making decisions that defer from the
normal covering and coating process.
Take care,

John Hauck knows more abot this than I do from his years in aviation.
Did not Wittman forget some necessary process that attached the coveing
to the frame and wasn't he flying in a very high velocity aircraft at
the time of his death. The current discussion about alternate coatings
involves ultralites which rarely exceed half the speed at which Wittman
was traveling when the covering let go. This is a key point in these
matters. Ultralights are slower so the loads are lower. Only the
approved systems should be used n fast planes or those intended to carry
more than one person at speeds over 65-75mph in my opinion.

Think of the sheet as a filter. It passes Blue since that is what you see.
There is no reason to believe it doesn't also pass the adjacent color UV
that you can't see. I do believe, however, that the sheet blocks all light
to some degree and would expect some attenuation in the UV just because of
the fabric threads.

OK, for what it's worth, my understanding has always been this: U/V will

is why a closed car gets so hot on a sunny day. (Especially my

blue fabric eliminating the U/V on my tail feathers, or enhancing it ?? Or
will it make any difference ?? I think, just for my own peace of mind,
that I'm going to cut a chunk of plywood to cover them, and hide them behind
it. I'm not sure how that translates to curing adhesives thru glass with
U/V light, cause I've seen that work too, and I know you're right. That's
the main factor in my deciding to really cover the fabric, and not take a
chance. As far as the further coatings go, I'm pretty well committed to the
full Poly-Fiber system. I should be able to fly for at least 10, and maybe
as many as 15 more years, health and physical systems permitting, and if
properly done and cared for, the fabric should last that long - even here in

Ah, the beauty of ultralights and experimentals! One has
the choice to do it his way. That is why I build and fly
these things.
However, when it comes to fabric and coatings, I personally
will install and finish like the manual states. No
experimenting or short cuts for me.
High speed, low speed, there are a lot of forces acting on
the fabric of our little airplanes. I don't want to be the
test pilot of an experimental covering process, now or
later. :-)
At times even certified methods of covering airplanes
fails. Sun and Fun 1984 or 85, I watched the fabric depart
the top right wing of a brand new Great Lakes biplane.
Sounded like a violent explosion when the fabric let go.
The pilot was lucky. He was able to hold the aircraft level
at 400 feet long enough to fly out of the immediate airport
area, then jump with a good parachute.
I like to remember that that thin piece of cloth also gives
tremendous strength to the wings and flying surfaces of my
airplane.
Anyhow, I am not telling you all what to do nor not to do.
I am telling you what I will do and not do. :-)

Hi Kolbers,

great success, but recently my supplier went out of business and I decided I
would give Pennzoil a try. Unfortunately I am having a difficult time
locating any in the local retail department, hardware and/or auto parts
stores. I try to explain what I want, but they just keep referring me to the
2-cycle outboard motor or multi-purpose 2-cycle oils.
Would someone please let me know what the stock number is (located on the
back side of the container) for Pennzoil 2-Cycle Air Cooled oil. Then, when
I find someone willing to order it for me, I can be assured of getting the
proper item.

<< A couple of questions
is all of the white on the whole wing film? >>
Hmmmm Not sure I understand the phrasing of the question. All of the white
you see IS film. The white only covers the rearmost area and the stripes
between the blue, yellow, and red as you can see in the photos. White does
not cover the whole wing with the other colors added on top of it. Each color
break has -inch overlap only. And the reason is that it's VERY difficult to
get the film to cover itself without trapped air and bubbles. Maybe good
hobbyists know an easy technique to solve that problem, but not me.
<< was the $650 for just the film or for film and the stits products? >>
For ALL the stuff - film Poly-Fiber, Poly-Brush, Poly-Tack, all film, etc.
but only for the wings. I think the cost for the rest of the covered areas
was about $250. That may be a little less expensive than a good, complete
paint job, but I'm not sure.
<< what size, length width and thickness of flim did you use? >>
Top Flight's EconoKote comes in 26-inch widths and lengths of 6 feet and 25
feet. I used some of each size. I don't know the thickness but it's quite
thin, say, about 4 - 6 mils maybe. I made scale drawings of the items I had
to cover (tail, cage, & wings) and drew the color scheme that would best
utilize the material. I used this to make purchases. I only deviated a little
from my drawings in the final application, however, there was still lots of
film left over. I tried to minimize seams at the expense of extra material. I
cut the film to the strip width I needed on a band saw while the film was
still on the cardboard tube roll. With the right bandsaw blade and slow
feeds, the edge result is smooth.
<< can you see the seams? >>
The only noticeable seam is the white seam that runs spanwise out the wing at
the 26-inch dimension from the trailing edge. I found that a white seam is
more noticeable than other colors because it's somewhat translucent. This
happens to leave an interesting appearance to the wing. The dark blue and red
joints and occasional patch are not easy to see at all.
<< would you do it again this way even if painting were an easier option for
you? >>
If I had the talent, equipment, and facility and enjoyed painting I might
paint it. Mainly 'cause this film covering may detract from resale value
since it's a "non-standard" finish. I plan to keep this Firestar for a long
time so resale is of no consequence right now. In my opinion, this covering
routine is a lot easier than painting and much quicker. The Poly-Fiber
covering is the same either way, but I'll guarantee you can't get a good
multi-colored finish with paint in the same time or with the same effort.
Ughconsider the sanding and taping .Ugh. Also, the film very easy to keep
clean and shiney. I use a bit of the new automotive silicone spray wax on the
leading edges and later just clean bugs and stuff off with Windex - just
spray and wipe and it's like new.
<< Was the Great Plains Coverite used as the white on the FS or only on the
Spitfire? >>
Yellow Coverite film was the only film used on the Spitfire, specifically
known as Great Plains Coverite 21st Century film. Top Flight's EconoKote in
all the colors shown was used on the Firestar - no Coverite.
<< is EconoKote available in the white? is either one better, worse,
cheeper then the other? >>
EconoKote is available in white and lots of other colors, about 10, I think.
Don't know about better or worse. EconoKote is less expensive than Coverite
but I picked it because it's available in 25-foot rolls. From Tower Hobbies
(online at: www.towerhobbies.com) EconoKote sells for $7.99/6-foot roll and
$37.99/25-foot roll. EconoKote has a tensile strength of 25,000 psi (for
whatever that's worth) and a weight of 0.20 oz/sq.ft.

Bill, I have an original Firestar with the old style 447, no CDI and I
switched from Penzoil to Klotz and then to Amzoil 2 cycle racing oil. It
is meant for aircooled 2 stroke engine and is fully synthetic. I found the
EGT down almost 100 degrees immediately (1250) --the plugs are brown and
clean. It costs about $8.00 per quart--cheaper by the gallon but I like
the stuff. I also do the Seafoam treatment regularly. There is a
concern that the synthetics oils do not do a good job of residual coating
of interior engine parts but I fly every week or two even in winter. If
the engine sat longer I might use something else or fog the engine.
Liquid cooled engines have more choices for oil but air cooled engines
need the best lubricants that run clean.

I may be wrong but I think one of the benefits of Tyvek is that it is
pourous and does breathe letting houses self adjust. It's main purpose being
to stop drafts. I may be wrong, it has happened before. Of course one coat
of house paint ought to seal it up real nice.

Seems like it might be a little of both. I understand that we "see" a color

Fine, but in this case the sheet looks blue, ( reflecting blue ) but also
transmits some of the light, ( passes blue ) although it's much dimmer
inside. I suspect partial to good protection because of absorbing part of
the light, but as I said the other day, I'm a-gonna cover it up, to make

Big lar, I work for a large medical co. and we use Tyvek for the packaging
of our catheters and stents, after they are packaged they go through a
sterlizing chamber process. I have talked to the rep. who we purchase this from
but never about using it for covering, that is I never new, however I'am going
to be seeing him next week again and I can ask him about it if he has any info.
on this. btw we use about 12,000 sq. ft. per day.

What sounds "neat" can kill you. IMHO--My "very" humble Opinion.
Geeze-don't want to step on any toes again-but...fabric is important! and
I'm not trying to be a know-it-all.
Example: I almost shot myself down with a nose mounted rocket-worked great
the first few times but....
Thought I would put "fins" on the front "and" fins on the back, because
that was what the "cruise missile" looked like-and it looked "neat"!
Accidentally hit the fire button with my elbow while I was climbing. It
fired---I saw the smoke stream...it turned up- (because of the fins up
front)---2 seconds later I saw a streak coming back at me, no telling what
the closing speed was-(I'm guessing 130-140mph) - I did not have time to
react, except to turn my head to the "right"- (like "that" was going to do
any good)! It hit the bottom of my left wing-the plastic fin cut a 5 inch
slit in the bottom of the wing- the rocket left a black streak along the
bottom of the wing, thank God it didn't hit the Prop! Now I don't redesign
the rockets-I leave them alone-they only have fins on the back for a reason!
They make fabric a certain way for a reason-not that I know why, but Ray
Stits sure did.

Hi Kolbers,
I have been using Castrol Super Snomobile 2-Cycle oil for several years with
great success, but recently my supplier went out of business and I decided I
would give Pennzoil a try. Unfortunately I am having a difficult time
locating any in the local retail department, hardware and/or auto parts
stores. I try to explain what I want, but they just keep referring me to
the
2-cycle outboard motor or multi-purpose 2-cycle oils.
Would someone please let me know what the stock number is (located on the
back side of the container) for Pennzoil 2-Cycle Air Cooled oil. Then, when
I find someone willing to order it for me, I can be assured of getting the
proper item.
Thanks,

i shouldnt have said air tight but it is very nearly air tight. it is
permeable to water vapour but if you try to blow air through it you get
nowhere fast. it is liquid water proof as well, they sell it as waterproof
breathable windbreakers at target.
John H. I would agree that without very careful testing no one should try a
new covering system. but remember that stits is a "new covering system" and
if no body experimented to figure it out we would be flying cotten and dope
still, and if nobody tried cotten and dope we wouldnt be flying period.
when i say i would like to try tyvek i dont mean I am going to throw it on
my firestar and go flying!!!!!! I am going to make a frame and try it out
and see what kind of properties I get compared to stits. if they seem
acceptable then maybe I would cover a fuselage or some none criticle part of
an airplane with it and wring it out for a few years. thats how we make
progress.
Polytack should work on tyvek is because it has surface texture, it is looks
sort of like cotten candy pressed into a sheet. very fine fiber size.
i was wrong, tyvek is polyethylene not polyester.
according to the maker
"Tyvek is DuPont's brand of spun-bonded olefin - a high-tech fabric created
by DuPont from high-density polyethylene (HDPE). The manufacturing process
creates a unique balance of properties that are ideal for a Protective
Cover. Protective covers manufactured with 100% DuPont Tyvek provide
superior protection from harmful environmental conditions. product is
lightweight, easy to handle, and provides superior protection from water,
dirt, dust, UV and IR radiation and many chemicals. "
note that UV and IR light dont hurt the stuff.

This is interesting, and if he tests it the way he says, should be OK. I
think I'd be most concerned with glue adhesion, and does it really shrink.
We have high density polyethylene 15 gal. buckets on the roof of the hotel,
( Ritz-Carlton, Rancho Mirage ) with some mighty potent chemicals in them
for the boilers. Nalco 2548 for example. Those buckets are translucent
white, and have been up there for years in the direct sun. I've been there
3 1/2 yrs, and they were there long before that. Still look, feel, and flex
like new. Hell for tough. Which plastic you've got makes a huge
difference, and you can't tell by looking or feeling. We also get 1/4"
translucent white tubing, for the chemicals, and for the pneumatic a/c
controls. Looks and feels like the stuff in the buckets, but degrades and
crumbles within a few months in the desert sun. Interestingly, the black
tubing which feels the same, and which you can buy at Ace Hdwre will last a
long time in the same place. I think (??) it's because the black absorbs
the U/V, but then again, it could well be a different plastic entirely.
I'll be interested in hearing what that rep has to say about his Tyvek
packaging. Sorry folks, Vamoose is still going to be covered with the
full Stits/PolyFiber process. I'm doing plenty of experimenting already;
somebody elses' turn now. Big Lar

I've gotta go with Possum. Why in the hell would you mess around with a
system developed over years & years by Ray Stitts & others I can't
understand. I almost want to say, "Use your brain Kim."
The instructions for use with the polyfiber system are very, very, very
explicit about mixing other products & UV protection - they say in one year
the fabric will deteriorate w/out proper protection. Model airplane film is
for model airplanes.
I'm no rocket scientist, & I know that many innovations and inventions have
come from people doing what wasn't accepted as ok in their day, but I sleep
better just following the directions from the people who designed &
developed the systems we depend on for our very lives. Otto Lilienthal died
flying one of his gliders after hundreds of glides...God bless him for
advancing aviation, but that doesn't mean the rest of us have to play black

Something in here has been itching at my head, and it finally came clear -
when I was trying to get to sleep for a 5:00 AM wake-up. Poly Tak, and
Poly Brush don't really stick to the Stits fabric, they soak through and
encapsulate the fibers, so that glue is sticking to glue, and the fabric
happens to be in between. The Poly Tak sticks the whole mess to the
aluminum. I mentioned in the previous message that I'd be concerned about
adhesion. Tyvek may be slightly porous, I'm not sure, but I do know that
it's not a woven fabric, and will hold water. I really question whether the
Tak and Brush will stick that Tyvek down. To properly glue a plastic, you
need a solvent that will melt the surface, and effectively weld the pieces
together. That's fine, but if you "slightly melt" the Tyvek, what
properties will the joint have ?? Will the solvent stick to the aluminum ??
Will the partly melted Tyvek stick to the aluminum ?? From what our
experimenter said, he sounds like he's got a conservative, well thought out
plan of action, and that's good. Be careful. Someone mentioned the
Wittman crash earlier. If memory serves, didn't he mix techniques between
dope/cotton and Stits, with a resulting loss of fabric from the tail ?? At
200 mph ?? Earlier today someone else cautioned about that very thing,
using that example. Someone else expressed shock that someone would try
techniques that weren't tested and proven. Most people would probably agree
with him, but the point was also made earlier that this is how Stits, and
Ceconite, etc. came to be, and are now accepted as the industry standard.
If someone doesn't try new things, no progress will be made. It takes all
types to make this whole system work; none are completely right, and none
are completely wrong. We're all necessary, so I don't think it's
appropriate to chomp either on those who do, or those who don't.

The drawback to Tyvek as a covering would likely be an inability to
properly tension it. Also Polyethylene is very slippery stuff and the
types of paints that bond with it are kinda limited. I am a
screnprinter. I have printed banners made of Tyvek. There are special
inks (paints) for it. They tend to get stiff and crack if applied too
thick. This is my firsthand experience with it. Also there are different
grades. Now many of the large format digital printers are capable of
printing directly onto Tyvek. Outdoor durablity is not long at this
time. This type of Tyvek is corona treated to be ink and toner
receptive. If you want to test Tyvek try to get some of this kind from a
large sign and banner supplier.
Good luck

If I remember right, Steve Wittman had used an older type technique when he
covered the wings of his airplane. The wings were all sheeted with thin
plywood, and then the fabric was used over the whole wood wing as a
finishing and smoothing layer.
This is a good way to do things, has a long history.
With cotton or linen fabric, you can use aircraft dope as an adhesive,
laying the fabric over the wood, and then doping over/through it.
As the dope penetrates the fabric, it sticks the fabric to the surface
underneath, and it makes a real tight attachment, especially doping a large
sheet of fabric over a flat sheet of wood.
If you have been around long enough to remember covering model airplanes
with silk, and doping the silk in place with Aero Gloss or Testors dope, it
is the same idea exactly.
When Wittman laid the fabric over the plywood, he did not properly attach
it down. Can't remember exactly how he mixed apples and oranges, but
whatever it was that he used to attach the fabric out in the middle of the
span, the airflow began to suck it loose from the plywood, and his airfoil
began to radically change shape as the fabric sucked up.
I am thinking (and could be wrong) that he glued the edges down with
Polytak, or it's equivalent, and then just used Polybrush everywhere else,
expecting the doping effect of the Poly-brush soaking through the Dacron
into the wood to hold the fabric in place. It didn't.

I don't have a problem with people experimenting with anything. Especially
the model airplane film over the fabric, I've seen it and I think it looks
fine. But when people start talking about wrapping their wings with "Saran
wrap" and crankin up "Old Yella", I'm just afraid that someone will
actually do it.
As far as the rockets go, I'm not talking about the "big" ones that Hawk
mentioned, just "model" rockets- kinda big model rockets- but just hobby
shop stuff. Don't really shoot them at anything in particular, maybe a
buzzard or two, mostly just "fly-in" fun stuff. Besides, they worked out
better that the "Paint ball" gun idea.

Well ok. I wasn't trying to be HARSH about the model airplane film on the

As best as I can recall Steve covered his wings using polyester fabric but
traditional doping systems for the glue/paint. Traditional doping systems
will not hold down polyester very well. Steve's very high speed plane flew
many many miles very fast with this mixed covering job and then he had a
delamination at high speed that resulted in the wing fluttering off the
plane. thats what I remember anyway.
yes this flying business is very dangerous. no you should not go messing
with covering systems without a scientific testing approach. yes we should
try other systems so we can always use the best materials and system
available. Tyvek covered with film might be a fantastic way to go, or it
might not work at all. there has been a none flying, static display in the
ultralight area at Oshkosh the last couple of years of a flying saucer
shaped "plane" that was covered using tyvek. it looks very much like a
polyester job done through a first thin layer of silver, but if you look
closely you can see the words tyvek printed all over the fabric. if you go
to Oshkosh and its still parked out there by the barn check it out. I am
going to play around with it on some frames and see if it works at all. You
got to remember that the only thing magical about the Stits method is that
Ray took the time to experiment with it until he found and documented a
system that works. it is polyester fabric from the fabric store and some
vinyl base solids desolved in solvents. The fact that Ray came up with this
system was that that was what a very clever guy could find that was
available at the time. just having to be near MEK is reason enough to use
some system other then Stits. you guys have been making fun of it, but that
stuff is really nasty.
I am kinda stunned that anybody would be against trying to improve on Stits.
I think Stits is ok but I am sure not thrilled with the stuff. expensive,
time consuming, high skill level required and poisonous. a couple of wiffs
of aerothane will destroy your lungs folks. whats to love. oh thats right
it does look nice and holds up real well IF applied correctly.
by the way my main interest in this is I hate to paint. If I can get a
great looking finish without having to fling gazillions of micro particles
of plastic desolved in solvent at my wings and hope that the resulting film
of solution dries into a smooth shinny layer of plastic I am inclined to go
with it. Makes more sense to me to just take a sheet of perfectly smooth
cured plastic film and stick it to the wing in a couple of pieces.

I am almost certain that they angle down a little [as on my Firestar]. If
you were to invert the engine [for some reason] you would have to remove the

As some of you may remember quite a few months ago I
posted an ad that I have wanted an ultralight since about
1980 but never had the guts or the timing was off, whatever
the reason it just did not happen. It might even had been a
blessing ( states Ralph burlingame of mound , mn.) early
designs were just so,so. one person on your list even had
the guts to say " if you havn't done it by now it will
never happen. I kept this persons e-mail but I will not
mention his name for the sake of embarrassment. he knows
who he is. I have been just lurking at the list for over a
year now, and I'am astounded at the wealth of information on
the list. I have wanted to purchase a kit, but it was very
time consuming. and my hobbies include, scuba diving through
the ice, hunting , fishing , collecting antique john deere
tractors and stationary gas engines, and golf. that's maybe
why I never purchased one before. It seems even the ones
that came up on the list were always about 1200 miles from
mn. I have even bid on kolbs from the ebay site, not a good
idea when your 1600 miles. well my ship finally came in. a
1995 kolb fs came up for sale a short time ago that is 95%
built and about 50 hrs. to go on completion. It has a BRS
chute, brakes, full winshield, ect. all I have to do is
install the winshield, gauges and complete the wiring and
instal the chute. this is where your help comes in, can you
tell me where the best location is to place the chute or is
this just a matter of preference. I would also like to know
where there are some afi's or bfi's that owns a mark III and
lives in the state of nd, sd, iowa, or wi. I need to take my

Congrats on your purchase. I have my Second Chantz soft pak chute installed
between the wings and use a lexan center section gap seal. The rocket motor
points up vertically and protrudes thru a small hole in the lexan cover.
Then there is also a flap in the lexan that will open up permitting the chute
to be extracted by the rocket The lexan cover was a modification, by Kolb,
to the original fabric gap seal. I modified it further (slightly) to
accomodate the chute and can still remove it easily to fold the wings, which
I do each flight.
By the way, Homer Kolb was also an antique John Deere tractor collector!

I hate (sure) to monopolize the List tonight, but something occurred to me a
couple of minutes ago, while sending a pic of ole Lar with his famous
covered rudder. Long ago, when I first started whining, some one mentioned
the idea of putting the Poly Tak into a squeeze bottle, and applying it with
the bottle and a finger. Have any of you tried to find just the right
squeeze bottle when you want one ?? That's another story, but I did find
the ideal bottle for just $1.69 at Rite Aid. ( Hate that name ! ! ! )
Well anyway, I tried it, and boy would I make PolyFiber rich. There was
'Tak everywhere. I think I'm safe in saying that that section is Solidly
Glued Down ! ! ! So, it went by the wayside. Then the other day, some
one - and I deleted the message, so I can't give you credit - mentioned
something to the effect of using the bottle with a BRUSH to spread the
'Tak. Yesterday I whupped myself out to the torture table after work, and
had at it. Got to looking at the squoze bottle, and the idea went "Ding."
Grabbed the bottle and an acid brush, and used the bottle to lay down a
medium bead of goober, and kinda paddled it along with the brush. WOW ! ! !
Fast, even, and neat. Laid the fabric over it, slopped it with MEK, and had

You have presented a very good discussion of the issues that are
involved here. Standard aircraft polyester is woven in such a manner
that the PolyTak can be forced through the weave and encapsulate them,
thus providing adhesion. Polyethylene is also a very smooth surface
just like polyester and any adhesion must come from similar
encapsulation. If Tyvek is really so tight a "weave" that it will hold
water, I doubt that sufficent adhesive can be forced through the weave
to provide encapsulation. As you point out, adhesion can be obtained in
some cases if the adhesive contains a solvent that will soften the
surfaces. In general both polyester and polyethylene are not even
slightly soluable in any reasonable solvent.
Yourself and several others have pointed out that the current "standard"
systems were once unproven and were developed by experimentation. No
argument there, but I have questions as to whether most people
understand just what such experimentation means. Much more is involved
than simply making a couple of test panels and working with them.
Anyone who has not had a background in such research should proceed very
carefully. There is more to proving a new concept and procedure than
meets the eye.
Last, I have to ask the question "Why?". There were clear and evident
problems and reasons for dissatisfaction with the old cotton and Irish
linen plus dope systems, and the interem systems of polyester fabric
with nitrate and butyrate dope still left much to be desired. Hence
there was much to be gained when Ray Stits (note there is only one t)
set out to develope something better. Today it is difficult to see what
would be gained with the processes being discussed.

Sure glad you put the (??) after "slowed down", because this is
meaningless. ALL electro-magnetic radiation travels at the same
velocity under all conditions and cannot either be speeded up or slowed
down. The difference between UV and IR is a matter of wave length, with
the shorter wave lengths (high frequency) being more energetic. This is
not changed by passing through glass or any other media. Light as we
think of it has a wide range of wave lengths from the long IR to the
shorter UV. In traveling through a media some wavelengths are absorbed
(media heats up) and/or reflected back.
The fact that one cannot see light coming through a media does NOT
insure that wavelengths outside the visible spectra are also blocked.

He used nitrate dope for this purpose instead of following the

Go check the Buzzman Web page

Here what he is saying about the carb intake manifold.
-----------------------------
Inverted installation problem with the Rotax dual
carb 503 engines.
If you are using a dual carb 503 in an inverted
installation you must turn the aluminum intake manifolds
over - once again the engine was designed to run
spark plugs up. On the 503 dual carb the inlets -
when the engine is upright have a slight upward
incline. When you turn the engine over this incline is
NOW down, which necessitates the removal of the
intake, turning it 180 degrees and reinstalling it.
Hope this help

> attacking the plane
A technique was developed by my PolyFiber dealer that works great. He
uses a squeeze bottle similar to the ketchup/mustard bottles seen in
some restraunts. It has the pointy shaped cap with a small hole. The
procedure is to simply squeeze a bead of PolyTak about 12" long, spread
it quickly out with the finger, and apply the fabric. Then move along
to the next 12" section. This works well if the surface is horizontal,
but if it is vertical one uses a slight modification. Place the tip of
the bottle against the surface. Place finger of left hand against the
tip and the surface. Squeeze and move bottle tip and finger together.
Finger acts as a dam and one gets the appropriate bead of PolyTak.
Spread the bead over the surface and apply the fabric. Thinks work best
if the bottle is kept relatively full of PolyTak as this permits a more
controlled feed by gentle squeezing. I keep a rag draped through my
belt and quickly wipe the finger after each application.
Prior to learning about this process I used a baby food bottle and a
brush. Within MINUTES solvent loss from the bottle takes place. In
dipping the brush and then wiping on the lip one starts to get a buildup
of semi dried PolyTak, and quickly starts getting lumps. The brush
itself soon starts to dry, and gets the buildup of lumps. The bottle
technique eliminates this completely.

Just sent out another post on this subject. Don't know what kind of a
bottle you used, but the rite (pun intended) kind of bottle works very
well indeed. Hole in end of snout was maybe 1/16". Believe source of
the bottle was Revlon. In using this bottle I used much LESS PolyTak,
with almost zero waste. Also, elimination of the lumps and gel slugs
of dried PolyTak made for much easier iron working on the cemented
surfaces..

The 503 I had on my firestar had oil injection, it injected the oil into
the intake manifolds from the bottom side of the intakes, engine upright,
you could rotate the manifolds 180 deg. but I believe, if my memory
serves me right , you would have to modify oil lines(longer). But this may
create a problem with gravity causing oil to drain out of the end of the
lines
while the engine is off, this may create problems during the first few
minutes
at start up? I believe my carbs were slightly tilted down.

Contact BRS. They have things worked out for a host of different UL

The intake manifold on a 503 DCDI can be removed and mounted in

The speed of light in a vacuum is constant but light has different speeds
through different media. that is how lenses bend light, by refraction.
defferent media also change wave length, reflect different wave lengths etc.
there is window glass available that stops transmission of 99% of uv and ir
light but regular glass does not.

I went out and got a blade style piper pitot off a Cherokee. Think I paid
$10.00 for it at the fly mart at SNF. It has a nipple outlet for both ram air
and static. I riveted a small aluminum plate at the front of the frame to
mount it on. It sets at the back of the nose cone, offset to the side from
the back of the nose skid. Works great. Leaves the nose uncluttered, and the
way I have it mounted I can tip the nose all the way down onto the skid and
there is still plenty of clearance between the bottom of the blade and the
ground.

I enjoy your messages a lot Gil, but this time I have to brace my feet a
bit. As Topher mentioned, light does travel at different speeds, etc.
Instead of 'slowed down', I should have said 'changes frequency.' U/V is
a high frequency radiation that goes right through ordinary car window
glass, but in so doing its' frequency is changed, or 'slowed down' to the
less energetic infra red, which can't penetrate glass, so is reflected back
on the inside, and is therefore trapped as heat, and parked cars get hotter
than H--- in the summer Specialty glasses I don't know about, except to
note that if you look at the windows of an energy efficient house at an
angle, they have a "sheen" kind of like an oil film on water. That must be
what he meant about u/v reflective glass. Now, if we could only adapt
that coating to our fabric, we just might have something.

You are certainly right about the change of velocity in media other than
vacuum. Got careless there. Three years after retirement and some of
the ability to think thoroughly before speaking seems to diminish.
Also agree with the rest EXCEPT for the changing of wavelength.

Gary, I know the preferred location for the chute is above the pilot in

There was an acrobatic circumstance in Disneyworld a long time ago when a
challenger pilot was performing acrobatics for the Disney show and his wing
popped up due to too much stress, I believe. It folded up against the other
wing as the plane began to descend and the pilot fired the chute!!
Unfortunately, the mortar that pulls the chute out of the canister somehow
got tangled up with some of the metal of the folded wing and the entire plane
and pilot was lost. The acrobatic show of the 5 Challengers at Disneyworld
was cancelled and to this day, I don't believe another one has ever been
reinstituted.
I have mounted my parachute under the gastank below the 5" tube for this very
reason. When my wing falls off, it won't fall down and my chute will have the
best chance of finding an area to deploy.

There are probably lots of good places, but here is a picture of where I
put mine, and it works great.
Both the pitot and static tubes extend not quite as far forward as the end
of the nose cone, so they cannot be bumped by someone walking by.
The pitot tube has the end open, the static has the end closed, and then
holes drilled in it a little ways back, I hope the picture will make it
obvious.

Momma said there'd be days like this, she just didn't say there'd be so many
of them. Yesterday afternoon, I was working on the......Gap Seal ??
.........Center Section ??.......what is that thing called anyway, that goes
over your head, and between the wings on a Mk III, and is made of lexan ??
I think of a gap seal as being the tape between the wing and aileron, etc.
Anyway, I spilled some lexan solvent/glue on the rear part of the 'center
section.' Worrying about getting the paper off it doesn't matter any more,
cause it's ruined. The rear 2 1/2 ft. of it has a large white blotch that's
non-fixable. So now I have a couple of options. 1.- Buy a new chunk of
lexan, and make a replacement for the ruined portion. 2.- buy a piece of
thin aluminum and replace the same portion. Here's my questions:
when sitting in the pilot's seat, and entering a turn, how much of the "roof
" do you guys look thru, if any ?? Seems like the forward 1/3 is about all
that would be useful anyway, unless your head tips back a lot farther than
mine. I'm thinking that making the replacement part out of aluminum would
make a good ground plane for the radio antenna..............?? Or would it
be too close to the engine, and its' electrical noise ?? If I use the
aluminum, how thin can I get away with ?? Or should I ask, how thick should
I go. What a tremendous burn ! ! ! You shoulda heard the squalling when
that damned bottle tipped over and spilled. Aaaaaaaaarrrrrggh ! ! !

Steaming Lar and Gang:]
Forgot to answer your question in the previous post.
I rarely look up thru the center section in a turn. In my
airplane I cannot use but the forward half anyhow. Sheet
metal last much longer than Lexan and is impervious to
gasoline. Not so Lexan. I have ruined center section and
windshield because of spilled fuel.
Antenna may be a little close to the engine back there. I
always put the antenna under the nose of my Kolbs, as far
from the engine as I can get it, plus the fuselage seperates
the two. I guess I could put the antenna out on a wing tip,
but don't want to do that. Takes too much coax cable.
Take care,

How can you keep getting yourself in trouble. A cheap and simple fix would
be to just paint the damm thing. You won't lose a lot of visability. On my
MK X I will have a permanent gap seal. The center section will remain on the
airframe at all times. There will be a 2" pad of closed cell foam glued and
covered on the side of the gap seal ( exact shape of the airfoil). When the
wings are folded There will be about 1/4" of squash to keep things sealed

should not affect the aerodynamics.Nothing to take off and nothing to put

Too windy to fly today so I worked on my "annual".
Changed the plugs. The old ones had thin black/brown coat after 14 Hrs.
After replacing the all fuel lines, the squeeze pump and the filter I could
not get the 477 to start. Bled the fuel lines in, resolved the primer pump
connection error (the crooked port is the inlet),...still no luck. Finally
found that the engine shutdown / parachute deployment switch had been
activated. The seatback cushion had been moved for access to a terminal strip
behind the seat and had bumped the switch to the shutdown position. The chute
safety pin was in place so there was no possibility of the chute firing.
Anyway... the engine started on the first pull.
Checked prop bolt torque and prop run-out and found that IVO to be right on
track, dead center. Checked the output of my Key West power converter and
found it to be 13 to 14 volts (no load). I'll change that puppy out for my
new Kuntzleman when I figure out how to mount the Kuntzleman.
Checked the fuel pump discharge pressure and got 3.9 to 4.6 psi. My best
trick so far was to use a spigmomanometer ( the ones used to take your blood
pressure) gage to determine the fuel pressure. The gage is calibrated in
mm/Hg and I wanted psi. I went to my ever-present engineers handbook found
the conversion factor and .... It worked! I had tried to buy a real fuel
pressure gage at S'nF but the good ones were too expensive.
I still have to remove the exhaust manifold for a rough check of the rings
and any possible scuffing. I'll lube the exhaust flex joints and inspect the
rubber isolators on the muffler bracket while I'm at it.
The air frame and fabric are next but they get checked pretty well during
preflight. This will be a two man check just to make sure.
I don't want to wear my plane out testing it but it is nice to know she in
good shape when I'm over areas where emergency landing spots are now
continuously available.

Oh, boy. I really feel for you guys spilling stuff. I had a good one happen
last week. An old friend of mine, age 81, was working on an R/C plane and
needed something to seal his fabric, used dope but just needed a little and
did not want to spend five bucks for a bottle. I opened my gal of poly
brush, 3/4 full and gave him a few onces. I put the top back on and stored
it in the cupboard above the sink in the kitchen of my trailer I use for
building. About two days later, I went in and there was a streak of poly
coming down from the cabinet into the sink. ALL of the poly was gone. It
had drained down the drain and almost melted everyting. It never melted
through - I wonder why not - but it did leave all the PVC soft and pliable.
Now, if it starts leaking I will have to replace the whole gambit. Lost
almost a gal of brush. Now, here is the good part, it melted the guys fabric
and loosened it from the balsa where it was attached and he has to start over
again. It really pays to be a nice guy some times. I guess it is only made
for stits products. G'day Ted

Kearbey et al: The conversion factor for psi to mm/Hg is 51.7. Thanks for
asking. I always wonder if there are any fellow gearheads out there reading
my posts.
Keep 'em flying, Duane the plane in Tallahassee, FireFly, SN007, 447, IVO,

Good Morning Boyd and Kolbers:
If I understand you correctly, needle adjustment was made to
one carb only. I would not recommend changing one carb
without also making the same change to the other. The 912
engine is run at the factory for 30 min. Everything is
adjusted correctly at the factory, except balancing
(syunchronizing) the two carbs. Just a WAG, but sounds like
you may have a carb sync problem rather than mixture
problem. If you change the fuel needle setting (controls
midrange mixture) on one carb, do the same to the second
carb. Eric Tucker told me that the 912 is tuned right on
the lean "edge" in midrange. I have found that at temps
below 50 or 60F the 912 will get too lean and start acting
up, i.e., feel like it is going to come out of the engine
mounts at times. Sometimes it will be more subtle, the
engine just doesn't feel sharp. When I detect this, I pull
on the enricher. If the rpm goes up it indicates I am too
lean in midrange and the fuel needles need to be raised a
notch. Seems if you use a more open free breathing exhaust
system the midrange problem is more pronounced.
The 912 is very fuel sensitive. If it is not getting as
much to drink as it wants it will definitely let you know.
3800 to 4800 is midrange where the engine is tuned on the
lean edge.
I do not use an egt on the 912 and do not intend to use one
on the 912S. First, I would not get to upset because the
egt's are not tracking identically. I personally do not
believe this is that important. If there is a wide gap
between readings, I'd check to see if my gauges were
calibrated and accurate throughout their entire scale.
Probably not. Then I would insure that carbs are in synch.
I do not operate in the 3800 to 4800 rpm range. My low
cruise is 5000 rpm.
Hope this helps you out a bit.

I wouldn"t change a thing. If you go for a lower cruise rpm you will hurt
your short field takeoff. Besides, 2 strokes don't like to run too slow;
below 5000rpm you will be running rich and will carbon up pretty fast.

Hi, Ralph. What type of synthetic are you using. I have just about talked
myself into switching from Pennzoil. I know synthetic is more expensive, but
to not have to de-carbon seems like a good trade.
