OK, Doug, you asked for it..........................ol' Lar's gonna give you
all a chance to flame away, for sure............... You DID say neighbor
friendly ?? My opinion (worth what you paid for it - thanks Beaufie) -
despite the recent, excellent series of comments about prop efficiency,
etc., is this: As the propeller tip speed approaches sonic, the noise
level goes up............period ! ! ! If some of you want to holler about
that statement, go ahead, but I'll stand solidly behind it............and
the back-up for my reasoning is this: on just about any day, (hour ??) at
almost any GA airport, you'll see, and HEAR high performance airplanes such
as the 182; 206; Archer; Mooneys, etc., taking off. The 182/206 seem to be
especially bad. The reason ?? On take-off, the constant speed prop is set
for minimum (flat) pitch for greatest rpm/greatest power. Logical, eh ??
On take-off, you want to get OFF the ground, and into the air. At 2600 -
2700 rpm, those long props' tips are nearing sonic speed, and the shock
waves are building up. The result - amplified by doppler effect - is a
loud, irritating "Brrrraaaaaaaaaaaaa" as the airplane passes overhead. I'm
sure we've all heard it, and tho' I love to fly, and will defend private
aviation to the death, I find that racket to be extremely irritating. Now,
picture non-pilot Joe Cool, having a BBQ with friends and family at his home
that he so wisely bought near the end of the runway. You can say
"Screw.............uh..............to heck with him" all you want, but enuf
of those idiots hollering can cause serious trouble for us. Read any issue
of AOPA magazine for verification of THAT ! ! ! I recently checked out in
a Cessna 172 with 180 hp engine/constant speed prop conversion, at Santa Fe,
New Mexico. Elevation over 6300 ft. msl. The drill.............fine pitch;
full throttle, for take-off. Gave us 2650 rpm. Don't know the prop length.
Immediately after lift-off, and I mean at about 100 - 200 ft., the check
pilot had me increase pitch slightly, to bring the rpm's down to 2500, while
still maintaining full throttle. The Reason ?? Noise abatement, he said,
and slowing it down a little drops the noise signature significantly,
without much difference in performance. Who keeps putting these
soap boxes in front of me ?? Incidentally, last Saturday, I flew that
180 hp C-172 into, and out of Angel Fire, NM, at over 8300 ft. msl., with
200# me, and a 220# friend aboard. Interesting...........and different.

I would think of another way to mount the balance weights. at an angle
along the bottom of the wing would be acceptable. If you are planning to go
fast with the plane it is especially importent that you do a very careful
test program that clears the ailerons on your very modified plane for
flutter. easiest way to reduce your chances of flutter are mass balances.
area balancing (spades) helps in some cases too. Spades at the wingtips
will work if the airflow there is pointed generally aft... but with the
wingtip vortex curling up around the wing you might find that the spade
located there is constantly pushed upwards, which you wouldnt feel since the
two sides would cancel each other out, and you would have a fairly high
constant load on the aileron system. Put a tuft out where you want the
spade and observe where the wind is going... if it is very upwards and not
very aft I dont think a spade will work in that position.

I have a friend who used to own a Kolb Flyer with a Cuyuna. He had a v-belt

support that bolts to the end of the engine and supports the large pulley.
He replaced it of course but advised me to fabricate a brace to support the
upper end of the bracket as I have the same redrive on my Ultra Star. It
makes sense because all of the push is concentrated on that bracket and the
four bolts holding it to the engine. Any one else ever have this problem?

Everyone,
I got my camera out of the shop, so I was able to get some photos of how to
tweek in an air speed indicator. I added two photos and some explaination to
the following jump. This technique is some what crude but should work for air
speeds that indicate too fast or too slow. I hope this helps.

Did your friend with the Cuyuna Powered Kolb Flyer have a
single or dual engine setup?
Was his a V or poly-V belt drive?
Was the redrive Homer Kolb's? Mine used an aluminum plate
about 5/8 to 3/4" thick.

His redrive was just like mine. It has four v-belts and the bracket is made
of steel . It has a slot that the prop shaft bearing slides up and down in
with a big hex nut between the large pulley and the bracket. There is a
3/8" threaded rod sticking out the top of the bracket. You loosen the big
nut then tighten the belts by turning a hex nut on the 3/8" rod. Once the
belts are tight, you retighten the big nut on the prop shaft and tighten a
jam nut on top of the first nut on the 3/8" rod to keep it from loosening.

That is not a Kolb redrive. Homer designed the
Ultrastar/Cuyuna/Redrive with two poly V belts and an
aluminum plate to attach to the engine and attach the prop
shaft and pulley. He also used an ecentric fitting to
adjust tension on the poly V belts.
Also, the Kolb Flyer was a twin. Not saying there is not a

I had one. I had a few problems running two engines so I simplified it
by extending the gear and adding an inverted cuyuna. Only flew it once and
sold it but the buyer never got around to flying it and let it rot outside.

I have looked at that and the problem is folding the plane. My new idea
is to have the rods meet at a point and then pin them together when folded
to make the ailerons more rigid for travelling on the trailer.

I think the 3 blade "Power Fin" is the quietest I've heard.
I don't have one, but several guys our club have them on their "503 dual carbs"
and 582s.
The "thrust/power" thing seems not to be a problem.
They're wider at the base than a Warp drive - maybe that has something to
do with it.
The "Trikes" use them along with silencers - they're mostly
built in England and other places over-seas and have to meet
certain "decibel levels" to fly them over there.

=======================
In a Kolb Larry, an easy answere would be the slowest turning prop. In other
words a multi blade prope to a high torque motor, where the blades are in
high pitch and the motor has the hp to to provide the needed thrust.
Lets not forget a good muffler, especially on a 2 cycle one.. :-)

I went thru all this long ago, when choosing prop & re-drive for Vamoose.
The VW engine will be turning about 3800 rpm at cruise, which, with the 2:1
re-drive will give prop rpm's of 1900. Prop is a 72" Warp Drive 3 blade,
with, so far, 13 deg of pitch at the tips. Looks like it's gonna need more.
Full throttle, which broke that re-drive on the 1st full power run was 4800
rpm, for prop rpm of 2400, and was achieved instantly. Thrust slammed a
550# scale against the stops. The noise level was pretty high, (so was the
adrenaline level) but it seemed to be a deep roar, rather than the high
pitched crackle I talked about yesterday. It only lasted a few seconds, and
the excitement level was pretty high. Didn't realize the re-drive was
broken at 1st, and I was grinning so hard my jaws ached. When I started up
again later, and the prop just freewheeled, I realized there was a problem,
and got this real sick feeling, deep in my stomach. Must've let go just as
I cut the power. If you look at the pics on my site, you'll also see that I
paid a fair weight penalty for real mufflers. Noise was a major
consideration in my choices, but my components wouldn't help Doug, cause I
have a 4 stroke, and my re-drive is a semi-custom unit. All my runs were
done while tied to a tree stump, but it appears that I was fairly
successful. Engine noise at low rpm isn't bad, (tho' it drew my neighbors
like a magnet) and prop noise seems (so far) to begin to drown out the
engine as it passes 3000 rpm. The new re-designed re-drive components are
massive, and allow for a little flexing. We'll see how they work out when I
get home. It's cool enuf in Palm Springs to work on it now. Talked
to the A&P who's covering my wings, and they're done, except for final color
coat. He says they'll be waiting for me when I return. Getting there,
folks; getting there. Hot Rod Lar.

His problems may have been self induced, he was helping me do an annual on

John/Gents:
Homer Kolb designed the Ultrastar redrive with a single
caged ball bearing supporting the prop shaft. As the
bearing started to wear (also no way to regrease the
bearing) the prop shaft would develop slop (play) in all
directions. There was no way to adjust this play out of the
bearing.
I discovered I could get two bearings on the prop shaft,
which corrected the slop problems for a while, but was still
not a permanent fix but lasted much longer than the single
bearing setup.

The person sending the e-mail did not give his/her name or where he/her is

Engineer, location and lab name to give some credence to his/her post.
When I first received this post I checked my axle fittings and didn't find a
thing wrong with them after hundreds of not so perfect landings at gross. If
I knew the lab's name and address maybe they can check them out for me ;-)
To me, it sounds like a competitor is trying to bad mouth the Kolb product

On my old direct drive VW I had a 60 inch wood prop. At anything over
2600 RPM the prop noise would wake the dead. At 3600 RPM most of the HP
was used to make noise not thrust. At least one prop efficiency
calculator said this was efficient. With my reduction drive VW I'm
running a three bladed 72 inch powerfin prop. With my 1.61 reduction
drive I'm turning 2250 RPM on the prop at my self imposed redline
(engine RPM of 3600) and the thrust is about twice that produced by the
direct drive 60 prop. At around 2200 RPM the prop starts to get annoying
but when I throttle back to a prop RPM of 2100 the noise is much less. I
have tried two other reduction ratios that reduced the prop RPMs by app.
100 and 200 RPMs at the prop and there was some additional reduction in
noise. With the working RPMs at or below 2000 RPMs on the prop there was
also some loss of thrust.

I have 185 hours on my Firestar2, never bent any gear legs or anything for
that matter. I have had a lot of great landings and some hard ones too. The
idea of a new reinforced gear axle fitting intrigues me. Not sure if it's
needed but I wonder. One could reinforce just about everything if they
wanted, but where do you stop. Keep it light and simple stupid is a good
idea. I was just wondering if anybody else has had a failure? is this the
same fitting design and tube thickness that is on the mark3's??.
Took my 5 year old daughter around the patch for the first time today,
screamed of joy and fun as we landed, guess she liked it. Guess I need to
build some doors so she can fly all winter with me. Me to as well. Getting
cold up here in the DC area, not to mention being worried about being shot
just getting gas.
Lets have some dialog here on the gear fitting, especially from Dennis if you
are still lurking out there. I would hate to tear up a wing if its a real
issue.

Let's see...Can you mount a flange to the crank for mounting the
propeller? Is the crank stout enough to handle the enormous gyroscopic
loads of a prop?
Will the power band of the engine require a redrive to slow the prop
down? (ask Richard Neilson if you don't have a good working knowledge of
prop speeds vs. prop efficiency ).
Does the block have some way that it can be mounted to the airframe?
Holes tapped in it that you can bolt a mount to?
One that is frequently a show-stopper...does it have a big oil pan that
will jack it up off the frame too high (when mounted on a Kolb-type
design (pusher engine)) And if you mount it low will you be able to
drain the oil? Will you have to dry-sump the engine?
And "plenty of power" in the case of the early VW Beetles was about
35-40 horsepower...
This is what I could think of in about 18 seconds...
The closest thing to a bolt on auto-engine conversion around right now
is probably the Raven Redrives packages and their all based on 1 of
about 3 different Suzuki (Geo Metro/Tracker) engines.
Of all the auto engines that I have ever heard of being put on airplanes
I've never heard of a Toyota ANYTHING being flown...NOT SAYING IT CAN'T
BE DONE, just that I've never heard of it. Have heard of Nissans, VW,
Subaru, Suzuki's, Honda, Chevy, Ford...go figure...Toyotas are good car

I've installed the Titan exhaust system on my Rotax 912 - the instructions that
come with it mention the use of some insulating sleeving on the fuel lines that
go near the exhaust. The stufff I find in the Aircraft Spruce catalog talks
about spiffy fittings that take a special tool, and not of the prefabbed stuff
seems to include the simple hose ends to go on the hose fittings that come
with the Rotax fuel pump and carbs. Can I just use the Firesleeve hose and slip
it over the existing fuel line (Gates 1/4 ID automotive) without fittings,
or is there something better? Thanks, guys.
Getting ready to take the plane out to the field, an operation called Flying Fun
out at Sundance Field just north-northwest of LaBelle, FL. Jim Hubbs runs the
ultralight operation. I hope to test run the engine next weekend, and get
the plane inspected soon after. Don't know what I'll do with that big hole in
my garage.

Hi Duncan/Gang:
I have about 400 hours on the Titan Exhaust/912/912S. I did
not use fire sleeve on my 1/4" Gates heavy duty fuel line.
I routed the fuel line and secured it so it would not make
contact or come close enough to the exhaust tubes to be a
problem. I use short pieces of left over fuel line for
standoffs (1", 2", etc.). Run black heavy duty tie wraps
through the fuel line standoff, around the intake manifold
(for whatever I am securing it to), back up through the fuel
line standoff, and around the fuel line. The fuel lines are
an important part of my preflight/postflight inspection.
john h
PS: I also used some fiberglass exhaust manifold wrap on
tube that is in really close proximity to the ignition
modules, and on the other side of the engine where a tube
comes close to the balance tube between the two intake
manifolds.

Thanks, John. Good tip about the manifold wrap - that was probably going to
be the next thing I would be pondering... at this stage of the
construction, I'm finding all the things left to do that I couldn't figure
out before. Everything left is some stubborn little problem I put aside,
some a year or two ago. "I'll figure that out later", I'd say. Well, later
is now, and I sure appreciate the help.
Another thing to figure. I'll be trailering the plane out on an open
trailer - I have about 35 miles to go. I was planning on making two trips,
one for the fuselage and another with the wings. The fuselage will be
traveling backwards and I'm concerned about wind loads on the folded tail.
I was thinking about fitting some foam between the folded surfaces and
wrapping the whole assembly with the saran-wrap like plastic they use at
Home Depot to wrap carpet and flooring for loading - this would fuse the
surfaces into a single unit and keep the wind from getting between them. Is
this overkill? General advice on open-trailer transport would be most
welcome. Thanks in advance.

The stuff that you apply yourself and cure in the oven is not all that
great in my experience.
The best (cheap) thing we have found so far to keep the muffler black and
rust free is to sandblast it rust free, spray it with high temp black, and
then wipe it down with cooking oil frequently, especially when it is hot.
Just before you start up and go flying works well. The oil burns on, and it
won't rust.
Don't use old gravy, or pork fat, or the dogs will be chasing your airplane
down the runway, or trying to dig into the hangar...

it down to a professional place and they tried. It didn't come out like the
bottle said it would. I think it will protect okay, but it never gave the
finish they said it would on the bottle ( but that may have been me and not

I used it too - need a big oven. It works marginally at best.
I still have to spray over it with high temp paint.
But with that stuff on it I can take it off every 6 - 8 months (before it
rust)
- wipe it down with acetone or carb cleaner - and repaint again over the
ceramic.
I would rather have "paid" to have it done right the
first time. But they don't like doing "used" mufflers.

Ken, Group:
If you can live with a flat black exhaust, I have had good luck with Tech
Line Black Satin.I has been over a year, it seems to be holding up well and
no rust. (but my FS 1 never sees rain) The bottle says Mega High Temprature
Thermal Barrier Metallic/Ceramic coating. parts must be sandblasted and
clean. Spray on lightly, too much and the bottle says it will flake when
cured. Also, keep it mixed well, it settles out quickly. let dry overnight ,
reassemble and run for 30 min. to 1 hr. to cure. Seems like it cost around
$20.00 for 4 oz(Aircraft Spruce & Specialty), but I used maybe 1oz. to cover
my Hirth exhaust.

Ken,
I'm not so sure for low speed aerodynamics. If that were the case, why do
golf balls go farther if they are dimpled rather than smooth? My
Firestar paint is rolled on like painting on a wall and is not smooth
like a spray paint job. Could this be the reason it flies slightly faster
than most Firestars? Low and high speed aerodynamics are different and
this may be one of those cases where added roughness to the wing surface
may be an advantage for low speed aircraft (less than 100 mph).

without damaging it:
Polyfiber Paint Cleaning Solvent
Kerosene
WD40

Windex
Soap and Water
Automobile wax (paste and liquid)
Lemmon Pledge

Richard/Guys:
Ain't there sumthin about "cleanliness is next to
Godliness"??? :-) Think we ought to take a shower before
we work with Lexan?
Does make me curious though..........???
May have been chemicals from your deodorant or from your
bath soap. Or could have been all that pepper vinegar you
put on your turnip greens oozing through your skin.
Not long ago was finishing up my new lexan on my doors.
Last thing to do was put a drop of thread locker on the nut
for my door handle. Got a little too much on there and it
ran down the door. Results were the same as some of the
high test gasoline. Looked like spider webs, crazing. In

a Firestar wing, or extending just a tad?

Don,
How big a person are you and what is the shortest strip you plan to operate
out of?
I'm around 270# and our FireFly does pretty well though not as well as my
Hawk but with that short 22 foot wing what can a person expect. As for
gear, as with any Kolb don't get them to slow as when they quit flying,
they quit flying and drop in. Until your used to it flying it, carry a
little power and fly it in. Back off the power just as your about to touch
down. Seems to work well.

When I was building my MKIII, I considered building the wings to 32',
rather than the 30' the plans called for. I would probably have gotten
slightly better climb, made it a little bouncier on turbulent days, a
little tougher to land in crosswinds, and a little less roll authority. But
I kept it stock, and am glad I did. 30' is enough wing for a MKIII.
Fireflys seem to fly great, but I have noticed that they always seem to be
flying around nose high, and they even look like they would like a bit more
wing.
If it was me (and I am not an engineer, so this is shade tree mechanics
talking) I would probably build each wing 12" or 18" longer, and just
respace all the ribs and spar attach points, aileron sizes, etc. to
compensate. I would not extend the wings any more than that, because you
don't want to change the stress loads too much, so if you do extend the
wings, I would then reduce my manuevering speed a bit from what the factory
calls for. Then go with the VG's, make sure that your center section gap
seal has minimal air leakage, and you will probably have the most docile FF
in the country. It is already an excellent airplane (if I lose my medical
it becomes the airplane of choice) and since the name of the game is
tinkering the airplane to exactly suit what you want, if you are willing to
take away a bit in one area of performance, (top end) you ought to be able
to add in another area. (lower stall)

Richard/Gents:
I flew the SS quite a bit before I got into a FF. Up until
my first flight in the FF, I had no desire to fly it. A few
years back, the factory SS, my normal ride at Sun and Fun
had been sold. Was given the opportunity of flying the FF,
if I was interested. Said I would give it a shot and see.
My best discription of the FF is it is a little SS. What a
little hot rod!!! I had a blast flying it. Quick roll
rate, acceleration, and climb. Had not problem keeping up
with traffic. Handled the rough air that is inherent at
Lakeland's ultralight strip, although I did hit the aileron
stops occasionally while making full stall landings.
I am not sure what the wing incidence is, but if it is
similar to the SS, then not nearly as much as the Firestar.
Slow flight is gonna drop the tail in order to get the
necessary angle of attack, like the SS. Those FF's you saw
flying around with their noses in the air were begging to
fly a little faster.
I would not change the wing on a FF. If I wanted something
to land slower, fly slower, then I would get another
airplane, i.e., the FS. About the only thing I would do
would be put longer gear legs on it to get it in a good 3
point stance for improved landings and take offs. Would not
hurt to move the main gear forward a little to put more
weight on the tailwheel. I did put the FF on its nose when
taxiing down wind.
The FF handles turbulence well, better than the long wing
Kolbs. Lighter wing loading equals rougher ride.
Take care,

John/Gents:
Bought the bearings at a local bearing shop. Pull the old
one, take it with you to match up the new one.
The Kolb Ultrastar Redrive was basically an aluminum plate
aprx'ly 5/8 to 3/4" thick. Was not cast.
Two tapered roller bearings would be the way to go. Then
they could be adjusted to get the slop out.
> Would it be

Depends on what you want. I wouldn't spend the time and
money doing it. For that matter, have no desire to fly and
keep an Ultrastar flying. It was a good airplane, probably
the best ultralight at the time for its time, 1984.
However, it has some inherent problems that were designed
into it:
Prop in close proximity to the ground encouraged frequent
prop purchases because of grasss, weeds, rocks, sand, and
broken landing gear.
Rigid landing gear invited frequent rebuilds.
Early Ultrastars inboard rib/main spar attachment did not
keep the main spar rigid in torque. Aileron input at higher
speeds caused the leading edge of the wing to move up or
down, cancelling out the aileron input.
Had no inflight restart capability.
There were other problems with the Ultrastar that I can not
remember at the moment. It has been 17 years since I flew
mine.
Take care,

======================
Thats an interesting question, about exending the wings. If you extend the
wings you will loose top speed, also keep in mind that the longer the wings
the less g's they will take if you don't beef up the spar. You will gain
lower speed performance.
All the above is in direct proportion to how much you will extend the wings.
I would suggest you don't do it. You can always build a small extra wing
(biplane type) right over the fuseledge on the CG. From what I have seen of
the cage so far it can be done. As it hooks into the cage it will not
detract from main wing strangth, it will give you extra lift, but would you
have enough HP to take adventage of it?
I guess that's why its called experimental. :-) If I get really bored after
I am done with my M3X I may do it... it will be a detachable one though, so
if it does not do enough good it will be a hanger ornament.

Subject: | Re: Firefly droop tips? longer wing? |
Richard & All,
I'm not so sure a little extra wing would slow it down. Our FireFly moves
right along. If you think about it, if it is flying slightly nose up that
means it's cruising with a higher angle of attack to carry the weight on
the existing 22 ft wing span. A slight increase in wing span might reduce
the angle of attack required for level flight thus reduce the drag it
induces. I got into this a little bit when researching the effect
different wing spans had (20 vs 24 ft) when ordering my ThunderGull kit. I
found that the 24 foot actually cruised as well on that plane but at the
expense of an additional 20+ lbs. I was attracted to the shorter wing span
for hangar space reasons. I get nervous when people want to start making
changes like that without doing a complete structural engineering
review. Adding extra wing make change stress levels and points - would the
spars be adequate for the extra stress and weight - then what about the
struts, same thing. Would they need to be repositioned to handle the extra
tip stresses, and then if angle of the struts is changed, how would that
impact their stress and strength requirements plus there is the wing fold
feature that would be impacted. The FireFly is fine as it is, fly the
thing. The only changes I thought that had some possible merit was the one
change Jack Hart done to the flaperon regarding control sensitivity and
authority. I feel the flaperons are a little to sensitive for the amount
of stick movement - end up fighting yourself when in turbulence. The other
I still feel that would be beneficial to lessen its nose over tendency
would be moving the gear slightly forward, maybe an inch. If I were to do
it over the last one thing I would do is to modify the axle bracket by
adding a flange to it to permit using Azusa band brakes rather than the
heavier Azusa internal expanding brakes. Our has the enclosure which we do
like. By the way if any one is interested ours is for sale. Need to make
room in the stable, to many planes, not enough hangar.

John,
Interesting to hear you put the FireFly on it nose. I don't feel quite so
bad now. Done it while landing, wasn't the planes fault, something I
done. I agree longer legs would extend the gear further forward and help
reduce that tendency but then I would have even a harder time getting in
and out with my short legs. Note that with my full figure I am loading it
on the forward CG/balance point while sitting on the gear. So far I have
put it on its nose lightly one other time and my co-owner done it once him
self. I suggested to the Old Kolb Company that the gear be moved forward
just a little to reduce this slight tendency. They never did it. The
other thing I had them do was lower the forward cross bar on the seat. For
us short folk, it cuts into the back of your legs some. I since have heard
other request it when they ordered theirs and some that found out
later. Hope the New Kolb Company is listening. Its a good flyer though.

Been flying mine since 1985, still love it but I would like to get something
I can land on the water and carry two. This would be heading into a whole
different realm than flying ultralights. I guess we will have to wait and
see how sport pilot is introduced, it may force everyone out of even legal

The difference was early US's used the same technique for
main spar to inboard rib attachment as tailpost to
tailboom. Two 4130 tubes, inside, top and bottom of the
main spar. No 4130 ring. So nothing to keep the mainspar
from "oil canning" and twisting. Stick left to roll left.
The right aileron goes down. Main spar not rigid enough to
prevent twist, so the leading edge of the right wing also
goes down. Effect is cancelation of the aileron input.

How many hours does that equate to? I flew mine 385 hours
in a little over year 16 months). Then flew my buddies for
75 hours while I was building my Firestar. Like I said
previously, it is a good, fun flying airplane, but the
maintenance ate up my very limited budget.

You must have had one of the first ones. I ordered mine in 84 and it came
with the 4130 ring and a single 4130 tube that went inside on the top.
Later ones had ring and two tubes.

385 hours in 1.5 years, thats a lot of flying !!!! Unfortunately I do not
have this many now. I trailer my plane to the airport and one day while I
had one wing set up and was walking the other out when a gust hit and
flipped the plane over and broke one wing. Due to a new family, layoff, and
multiple jobs, I never got around to fixing for about 8 years. It has been
flying now for two years, but I am also remodeling a house so flight time is
still minimal.

Duane,
When we returned from London and I returned to my house the power had been
out for 6 hours. The next day I discovered that the power company had driven
heavy equipment over the runway and made deep ruts in it. So that sort of put
a stop to my taxi testing.
I called them and they finally came and filled the ruts and reseeded.
I did not take the plane out of the storage building until this past Sunday.
I made about six crow hops and the highest was about six feet above the ground.
I suppose now the next thing to do is take off and fly it around. I am reluctant
to do that at this short runway. I contacted the owners of the runway
you told me about at Coleman, between I-75 and the Sunshine Parkway. It is 4,000
foot long and they are ultralight friendly. I need to convert my open car
hauler trailer to transport the Firestar there. Will work on that the next few
days.
After I make a few takeoff and landings from the long runway, then I should
be ready to try it on this shorter runway.
Thirty years ago I would not even done any taxi test, I would have just taken
off.

385 hours in 1.5 years, thats a lot of flying !!!! Unfortunately I do not
have this many now. I trailer my plane to the airport and one day while I
had one wing set up and was walking the other out when a gust hit and
flipped the plane over and broke one wing. Due to a new family, layoff, and
multiple jobs, I never got around to fixing for about 8 years. It has been
flying now for two years, but I am also remodeling a house so flight time is
still minimal.

I'm lucky if I get over 35mph most of the time.
The question is has anyone towed open trailer ( My ship when finished will

Subject: | Re: Kolb Firestar ll- Axle fitting failure |
Will,
I appreciate your comments and suspicians. My message is not a Hoax it is
the real thing. Being a new member to the list I didn't realize I had to
identify myself. My name is Bob Erb and I live in Rochester NY. You have my
E-mail address.
I am a new builder, new pilot and new Kolber. The reason for my
communication was to share with the Kolb list an incident I had with an axle
fitting that failed and caused me many haeataches as outlined in the
communication. I thought the purpose of the list was to help each other and
present potential safety issues.
I belong to a club with 54 ultralight members with many different types
of aircraft. I wouldn't trade my FireStar for any other plane in the club. It
is my pride and joy. I have the highest regard for most everyone at the New
Kolb Aircraft co. especially Ray Brown who I worked closely with for two
years when I was building my bird. They don't come any better than Ray. Even
though I have a close relationship with Kolb, I felt it my responsibilty to
communicate what I feel and the engineer felt was a design weakness. We all
have our own opinions and I respect that. If fellow Kolbers want to ignore a
potential problem that is their call and their life. As for me, the axle
fitting will be number one on my preflight list.
By the way Will, the engineer is an ultralight pilot and has been for the
past 25 plus years. He has been flying the Kolb products and they are his
choice of ultralights. I feel we all have a responsibilty to make our sport
as safe as possible. Again, I urge all to inspect closely your axle fittings
especially those with a FireStar II. Kolb is doing their part to try to make
their products as safe as possible and are now reinforcing the axle fittings
on the FireStar with gussets. I comment them for this effort even though they
believe there is no problem with the part.
Will, again thanks for your input--- Bob Erb

Ken,
Yes, here is my open trailer that I have been using for 15 years towing
my Firestar 8 miles to the airstrip. Notice that it is very light so I
can use my 4 cylinder Grand Am to tow it. It has worked out very well
because there is a lot of shock absorption in the trailer's leaf springs.
I trailer at highway speeds even though it has negative tongue force (it
lifts off the ball when I disconnect it). The ONLY reason this works is
because the wing section hangs off the back end acting like a big
stabilizer as I trailer down the highway. I have not added tongue weight
because I like the idea of letting it sit on the tailwheel once it lifts
off the ball. I prop up the tongue, swing the fuse tube support down,
then it's ready to roll off once I undo the black tiedowns. It is stable
as I have trailered other Firestars through some extreme wind on a
two-lane highway with trucks passing in the opposite direction. I ALWAYS
use a lock, backup chain, and rope for safety.

I towed my Thunderbird (modified MK 111) from Canada to Kentucky. Thats
about 650 KMs. No problems and had it up to 60 mph on occasion but I did
the posted speed most of the time. I did have some damage from an insecure
aileron that banged into the tail section and poked a hole in it. Easy fix
anyway. Be sure you have a way of securing the ailerons so they do not move
at all and you should be okay. My wings were supported on the leading edge
to take weight off the wing support tube on the boom. The wings remained on
the fuselage. I saw no reason to take them off. I did remove the prop for
transport. I have a small v section on the front of the trailer which may
or may not affect aerodynamics. The trailer is one designed by Kolb and is
very easy to handle.
The trip was a learning experience and I have no qualms about
transporting it that way again in the future.

Hello Kolbers,
With the move to our new house nearly complete I am back on my Mk3.
Test ran the 912 again today.
At 1,750 RPM for ~ 4 min: Oil T122, Oil P62, EGT1923, EGT2925, CHT1117, CHT144.
Run time.4 Hrs. OAT was 79.
Drip leak at inlet to coolant radiator, tightened hose clamp but leak persisted
at same rate. Drip leak at fuel pump out let, tightened clamp stopped leak.
Engine idle had been set by mechanical method but turned out to be too fast (~2500
RPM). Idle was reduced by trial/error but engine was not smooth. There is
also a vibration that seems to be from prop (3-blade Ivo).
Coolant will be drained for inspection and repair of radiator inlet.
Vacuum gage will be installed on carb Xover tube to set idle.
If vibration persists after final tuning prop will be removed for balancing.
Also took a few minutes to fly the FireFly, reported on separate post.

Duane,
Good chance your carbs are not balanced. Notice the difference in CHT and
EGT. The carbs need to be balanced at idle with both carbs at idle stops
and at some throttle setting when carbs are controlled by cables.

Hello Kolbers,
The South GA/North FL beach run from Panacea to Mexico beach is now scheduled for
the weekend before Turkey Day and I want to be flight-ready.
Took time out from the Mk3 work to polish my FireFly flying skills. The objective
was to practice simulated engine out landings. I started by cutting the engine
to 4000 RPM on final and worked up to cutting the engine to 300 at the beginning
of the turn to base. I had to bring on some power several times but it
is great training. There is an old saying that calm seas don't make great sailors
but until I get better at it I prefer to do this on perfect days like today.
Things I knew but reinforced today:
Start with >800 AGL
Keep your airspeed:
more in turns
more on final so that you will have some left for touchdown
Watch out for quick loss of airspeed when you level off for touch down
FireFlys can start "mushing" and be falling like a rock before the pilot feels
the classic nose up/breaking stall. Mushing usually ends up with the tailwheel
touching first followed by a hearty touchdown of the mains. Don't ask how
I know ;(
My best landings were when the nose was just about level with the ground. Raising
the nose causes quick loss of airspeed and mushing.

That's great---I do believe the failure was on one of the newer Firestar's

believe that some measures were taken to strengthen the area. My information
is that it wasn't ignored by Kolb but acted upon.

Bob, welcome to the list and thanks for your reply.
I'm glad you understand where I'm coming from. I have been a member of this
list sense 1996 and have learned not to take every post at face value
especially from anonymous posts.
Yes, the list is for helping each other and present potential safety issues
like you did. But if the axle fittings were as bad as your engineer friend
say they are we would be hearing more about axle fitting failures just like
we hear about bent gear legs. If TNK changed the way they make the fittings
then they should post the potential problem on their webpage and urge us to
replace the fittings.
At the airport I fly out of, this summer we have seen 2 tow planes crash at
the runway's threshold due to dust devils. Last weekend I had to use full
aileron deflection on my FireStar during landing due to one of those dust
devils. I came in fast for better control and bounced 3 times. Chuck, the
Flightstar driver, was watching me land and jokingly told me the 3rd landing
was the best but he knows it can get exciting landing on runway 08. First I
checked to see if I bent a gear leg then I checked the axle fittings and I'm
happy to report they wear still intacted.
This list was a big factor in deciding to build the FireStar. I was stuck
between getting the Challenger or the FireStar. Had I read your post while I
was making my decision I may have decided to purchased a Challenger kit. Then
it would have been your fault every time I took out the nose wheel when I
landed out on one of those rough desert playas, yes I'm a good democrat,
blame everyone else ;-)

Well, fellow Kolbers, I just had the pleasure of introducing our famous? "Big Lar"

in my Firestar II and were lucky enough to see quite a large heard of antilope
and half a dozen coyotes. With his didgital camera clicking rapadly we may be
treated to some pictures on the list. It was his first flight in a small? ultralight
and he found it very invigerating to fly 10 or so feet high off of the
ground. It took some very pricise flying to try to out minuver those coyotes.
I mean they can turn on a dime, even tighter than my Firestar II. I arranged
for some of our other Kolb drivers to be at the field. We have 5 Kolbs at our
field.
Both this Firestar II and my single place KXP are up for sale and will appear

If Lar thinks they are good enough to go for a ride in, then they must be
OK. So Lar, Post some of those pictures if they came out OK.

You be very pleased with the Tracy O'Brien brakes. Friend put them on his
Hawk. Work great and install was a snap. He had the Azusa plastic wheels,
they also have a kit with the adapters for the Hegar wheels. Several other
Hawk owners have since added them and report their working just fine. You
will need a little info when you order them. Type of wheel, axle diameter,
and axle length. They even made customer spacers for my friends, not sure
they do that for every order.
Only be careful, they break very well - you will also need the 3/4" dia.
master brake cylinder if you go single control. Talk to them about this
since being a trail dragger you need to be careful not to have to much
braking power and nose it over.

I also can also recommend Tracy OBrien brakes.... compared to the 'other'
popular brands I found that they are considerably less expensive, maybe
because they fit the popular Azusa wheels that you may already own. Also
lighter in weight and plenty of braking power... I can hold my Firestar up
to over 4000 rpm runup (til the nose tips over). Use a hand lever on the
stick. My only problem is a gradual, mysterious loss of hydraulic fluid from
the system over time... but it still works fine until I top off with more
fluid. Can make some amazing sharp turns using the single lever (on grass)
using the technique I learned from John Jung (throttle up, raise the tail,
hit the rudder, gradually release the brakes... and around you go!)

It was great.................a Kolb-er's paradise. I think George, and Ed
Kiger, and their buddies have created one of the neatest little toy patches
around. Zooming around up there, it seemed like everywhere I looked, there
were airplanes parked by houses, or sticking out of hangars. I believe
George told me there were 35 members of the Black Mesa Flyers, of which at
least 1/2 dozen, or more, are Kolbs. Prescott, AZ, EAA chapter has over 150
members. This is an ACTIVE area. What he DIDN'T tell you were about the
snickers as ol' 6', 200#, pot bellied Lar crammed himself into the back seat
(??) of a 503 powered FireStar II. (I think it was really the luggage
compartment) Did he mention ducking as my knees waved around his ears, as I
tried to get rid of the cramp in my butt, caused by twisting (trying to
twist ??) to get a coyote picture ??...................that almost didn't
come out anyway ?? I also found that there's still room in my life
for the trusty old Nikon F2 that I've used with so much pleasure and
success, for so many years. The digital camera sorta worked, but by the
time I'd found my target thru that chintzy little viewfinder, set the zoom,
pressed the button 1/2 way, waited for the green light to come on, then take
the picture.......................at 65 mph, it did hamper my style a bit.
(??) Next time, the Nikon goes for the ride. See what I'll go thru to
weasel myself into another ride ?? I'm in the early stages of learning how
to edit photos in the computer, so the antelope and coyote pics are only
fair - I enhanced them as best I could - but still................I'll
publish some to photoshare tonight.................then it's up to Matt,
when you'll see them. Don't expect too much. Did I mention that
George is a sneaky ol' rascal ?? First, he took me for that jaw dropping
ride, over that neat country, where the antelope play, and the coyotes
run..................THEN, back at the hangar he shows me the cute little
FireStar I he has for sale. You think I wasn't about ready to write a check
on the spot, and cram that thing into the back of a certain Dodge Pick-m-up
?? Or tie it to the roof ?? Or even fly it home, then hitch-hike back for
the truck ?? Dirty Pool, Man ! ! ! A couple or 3 things DID
impress me.................He demonstrated rock steady hands-off flying for
quite a way, and that little plane seemed to handle the extra 200 lbs of
lard very nicely. It must be a gas, when he's by himself. When circling
the antelope, he made a couple of passes - not too close - then left them
alone, before they got too nervous. Even did the same with the coyotes,
which many consider to be fair game. Livestock, he stayed completely
away from, which impressed me even more, cause I know 1st hand (from
listening to livestock owning friends in Sequim, WA) how irate the owners
can get over dumb-shits buzzing their animals. Then he made a touch
followed by a full stop landing..............both wheel landings, and both
'squeakers.' (Are they still 'squeakers' in the dirt & gravel ??) We
lucked out, and got our flight in between rain squalls, then visited with
others. Many, many airplanes; many pleasant people, in a really nice

At the fly-in, we saw the new Obrian brakes they are offering. They said
they are so much better than Matco. More money! But worth the difference, is
what they said. Maybe we'll hear from some on the list who has experience
with the new brakes?

Jon, I have the same problem with my TOB brakes. I've gradually lost some
throw in the brake handle, and I'm squeezing all the way to the stick, now.
Previously, I could slide my wheels on grass when locked up.
How are you able to top it off without introducing a bubble which then
has
to be completely bled again?

Paul,
To the best of my knowledge, US's were sold as kits in the early to mid
80's. They are all basically the same, structurally, except for two
additions that were made to the later ones. one is, a brace was added to the
drag strut to hold it in column and keep it from buckling in a hard pull up
and the other was a 4130 steel ring, much like the one the fuselage tube
attaches to on the cage, was added to the root end of the wing spar to keep
the spar from twisting from up and down aileron forces. They were powered
by a Cuyuna, two cylinder, 35 hp, two stroke engine, mounted upside down
with a belt redrive. Some have been converted to other engines like Rotax.
I've even seen one with a water cooled Suburu engine. Bad things about the
US are 1) you are limited in prop diameter because of boom and ground
clearance to 50". And even at that they are prone to pick up rocks and
debris from the ground, damaging the prop and 2) They have stiff (rigid)
landing gears which won't take much abuse. Many have been converted to use
the tapered aluminum gear legs used on later Kolb models but they still bend
gear legs on hard landings. Most of the kits were assembled using carbon
steel rivets and they rust over the years which could weaken the structure.
On the one I am rebuilding which is an 84 model, I am drilling out the steel
rivets and replacing them with stainless. That's about all I can tell you.
I'm sure there are others who can tell you much more about them.
Hope this helps.

Use the original holes. The holes weaken the ribs an amazing amount so
any more holes would weaken it further. No one will notice if the holes are
out unless you point out the ones that are 1/16 out of line. You will also
save time and go flying sooner.

Dale, if the holes are drilled that much off center and you are not satisfied
with using the old holes, you can replace the tubing of the rib very easily
and drill new perfect holes you can be proud of.

I am at the point in construction where I need to install the floor

mounts? Does the seat webbing sandwich between the pan and the upper frame?
I don't want to permanently attach the floor pans, so that I can access
the hydraulic brake cylinders. Is there something better than pan head
screws? If the pan does angle up at the rear I will need to get a larger

There's a couple of pics there, that show the floor pans fairly well. Keep

Bob,
I saw the O'Brien brakes setup also. Spoke with Ray about them.......what is nice
about his new setup is they a made a device which bolts on over the heel brake
studs. This unit holds the master cylinders and easy as 1.2.3 to install.
He indicated pricing will be in the upper 3 digits. I interpret that as to
around $800.
That Ray is superior to Bob Villa.

At the fly-in, we saw the new Obrian brakes they are offering. They said
they are so much better than Matco. More money! But worth the difference, is
what they said. Maybe we'll hear from some on the list who has experience

Yes it does. It overlaps the front piece and lays on top of it.

Yes. Don't have a picture, but I cut out 2 strips of .024 aluminum (one for
each side) about an inch wide and laid them over the fabric so that the top
edge is as low as possible so that your legs won't contact it, and it
projects downward at the same angle as the floor pan angles up. The rivits
that attach the fabric go through it to hold it to the tube. There are
several places along the lower edge where I drilled holes and inserted
U-type tinnerman nuts. The upper edge of the pan lays on it and is held to it.
> I don't want to permanently attach the floor pans, so that I can access

>screws?
I welded extra tabs onto the tubes and used tinnerman nuts with screws. You
could rivit aluminum tabs and use U-type tinnerman nuts for easy removal.
Find a 2' x 3' carpet that matches your paint scheme, cut to fit, and lay
it over the pan when you're done. Drill and stick the screw through it.
Stops vibration and noise, and the screws won't vibrate back out.

Russ,
When Kolb started offering dual stick controls as an option on the Mark III
they quit turning the floor pan up at the rear. It was in the way of the
dual controls. I had the same question when I was building mine. You should
have 4 strips of aluminum about 5/8" wide and the width of the seat.

From: | Cavuontop(at)aol.com |
Subject: | Specification Drift |
Gentlemen:
While I was in London, KY for the Kolb gathering something came to my
attention which I think is ripe for discussion on the list.
The new TNK models, the Extra and Kolbra, despite their outward
changes, all use the wing spar and strut system devised by Dennis and Homer
for the Mark III. When I bought my Mark III the specs said the gross weight
was "800-- normal, 1000 maximum." Because the new models are heavier --seems
the average Mark III Extra is coming in around 575 lbs.-- there is not alot
of headroom after you load full fuel and a 200 lb pilot. In fact, if you
were playing by the rules most of the new planes would be limited to
something like a 90 lb passenger assuming 15 gallons and a 200 lb pilot.
The response of a number of builders has been to unilaterally raise
the gross weight of their planes. I saw a data plate on a Kolbra where the
builder stated the gross weight was 1100 lbs. He had a jabiru engine and a
full panel, and, as I recall, a BRS, so I suspect he needed it just to carry
a passenger.
I asked another Mark III extra guy to see the engineering calculations
he had done to justify the gross weight increase and he replied, "Kolbs are
strong." When I pressed him for the numbers he got annoyed and said, "The
design is very conservative," and told me as the manufacturer of the aircraft
he could set the weight anywhere he wanted. That ended the conversation, but
left me to wonder at the difference between that which is permissible and
that which is right.
In some respects I think folks like John Hauck and Rick Trader is
responsible for this cavalier attitude (and I make this observation with the
greatest respect). John has written about loading his plane to 1200 lbs and
above. Nothing has happened to him yet, which permits folks to draw the
conclusion that it must be OK. However, my rather primitive understanding of
structural failures in aircraft is that everything is just fine and dandy
until the wing fails upward just outside the wing strut attach point, or some
other similar scenario. Put another way, the failure is often instantaneous
and catastrophic, it doesn't give you any warning. So if you are operating
outside the envelope and you haven't had a problem yet it only proves that
you haven't had a problem YET.
Anyway, I am somewhat troubled by what I see as fuzzy, unquantified,
thinking on this subject.
Years ago a seriously obese friend of mine who was a partner in the
Cessna 182 I was flying asked me to fly with him out to Williamsport, PA to
pick up a couple who was staying with him for the weekend. We topped off the
tanks (80 gallons) for the trip. When we got to Williamsport we were met at
the ramp by the passengers. They looked like a pair of bowling balls. The
wife fatter than the husband. With the fuel we were carrying we were going
to be way over gross. I turned to my friend and said, "Why the heck didn't
you tell me were flying these enormous people when we got the fuel . . . what
were you thinking!!!!???""
He looked a little sheepish and said, "Well it said in FLYING magazine
that if you can close the doors on a Cessna 182 you can fly the load." I
suggested that the Pilot Operating Handbook might be more authoritative, and
made him take out the POH and do the calculations based on a combined
(estimated) passenger weight of 500 lbs. The calculations showed that we
would be out of CG to the rear and well over gross. When he was done I asked
him what he thought about the ride home. Astonishingly, he said that he
would still do the flight. When I asked why, he just gave me some hand-wavey
bullshit about the 182 being a great load carrying plane and the CG graph in
the POH being written by lawyers. It was evident that he thought that the
gross weight and CG limitations published by the manufacturer were merely
advisory and didn't apply to him when they were inconvenient.
What resulted was a scene on the ramp that embarrassed all concerned.
But the fact of the matter is that insurance companies (especially in the
present environment) are looking for excuses to deny coverage, and operating
the aircraft outside the published envelope is the equivalent of painting a
big bull's eye on your chest for the plaintiff's lawyer prosecuting the case
for the injured passenger.
The question is this gents: is it right to load our planes beyond
their recommended gross weight?

Hey Russ. Bill sending, still working on my Mark III Classic in Colorado.
I fabricated two aluminum inspection plates for the brake cylinders, one for
the rear floor piece, then one for the forward that overlaps the rear one
partially. The front plate is notched to accomodate the heel pedals These
are attached with camlocks. Also put two inspection rings in the fabric
just below the brake cylinders. This should give me good access just in
case I spring a leak. Call me if you have questions 303-838-2240. Good

Very good post Mark! My answer to your question is an absolute NO. Gross
weight figures are there for a reason and the lawyers didn't come up with
the figure. Some aircraft are more forgiving than others, and Kolb
happens to be one of them, but how far can a pilot carry it? I recently
bought a Honda Shadow motorcycle and noticed the gross weight is printed
in the operators handbook AND on the machine itself. Not only is it
printed, but they come right out and say that 'serious injury or death'
could result if that limit is exceeded.
We as pilots know all of this and tend to push the limits. I exceeded the
limits on that bike when I took my heavy son for a ride. I knew the bike
would not break, BUT a motorcycle is designed way beyond its published
weight restriction. Knowing this, I took responsibility and had a safe
ride. Aircraft on the other hand have this tendency to built up metal
fatigue, unlike the motorcycle frame that is made totally of steel. What
about weight and balance? The laws of physics are sometimes very
unforgiving and there are a few of us who have survived such catastrophic
incidences. We have all heard some of these stories right here on the
list.

I agree I hear this quite a bit of this also. When I have flown even the
factory Kolb MKIII with the 912 I know it is over gross but not to the
tune of 100lbs over. I had a long discussion with Dennis Souder on this
point back when he was the owner. He indicated that the design was
conservative but that was ALL he would say. I did get him to agree that
SOME overloading on a smooth day would be OK. He said he had considered
raising the gross weight limit but everyone seems to fly the planes over
gross, if he raised the limit and people continued to be as loose with
the raised limit people would die. My interpretation of the discussion
is the 1000 lb. gross weight is a warning flag if you get close to or
exceed it you need to compensate for it.
My personal rule is this. I will fly my MKIII at weights up to 1050lbs
gross weight but I will never fly fast in midday thermals at this
weight. If I'm flying in the 800-900 lb. range and below 80 MPH I should
be able to fly in reasonablely rough weather. Keep in mind my stomach
will not tolerate much so this should be ok.

When I did my dual training for a PPL in rented Cessna 150's, they
almost always took off, over gross, with full tanks. Full tanks were

that the tanks were not full. I was not impressed with general aviation
becuause of that.

The feel doesn't change much. I does ride thru the thermals better. It
takes more back pressure to keep the nose up but this can be trimmed
out. On climb out with high power at low speeds I find I'm holding the
stick back quite a bit. My MKIII has a higher thrust line than most so
it is worse than other MKIIIs. I think it was Richard Pike that warned
about flaps. I use flaps for landing if I had a missed approach and had
to do a go around I would have to raise the flaps to climb. I don't use
full flaps but full flaps with full power could cause a power dive. I'm
considering changing the balance of my plane. I would rather add weight
to the nose when I'm light than adding weight to the tail when I'm
already heavy.

In fact, if you
were playing by the rules most of the new planes would be limited to
something like a 90 lb passenger assuming 15 gallons and a 200 lb
pilot.
Considering everything you said...this is a trivial point. TNK (I
believe) has done away with all but the standard 10 gallon gas setup.
(I believe you have the 3 tank 15 gal. setup that Old Kolb did for
awhile...)
So add 30 more pounds to your passenger... ;-)

Hey Russ. Bill sending, still working on my Mark III Classic in
Colorado.
I fabricated two aluminum inspection plates for the brake cylinders, one
for
the rear floor piece, then one for the forward that overlaps the rear
one
partially. The front plate is notched to accomodate the heel pedals
These
are attached with camlocks. Also put two inspection rings in the fabric
just below the brake cylinders. This should give me good access just in
case I spring a leak. Call me if you have questions 303-838-2240. Good
Luck!
Bill,
I am a little confused about inspection rings in the "fabric" to
get to the cylinders. The cylinders would be above the nose cone when
it is installed. I am making an access panel under the nose cone to get
at mine (realizing that you can drill out a couple of rivets and the
remove the pan above the cylinders...forward pan, not the rear pan...)
Anyway to make the access hole in the fiberglass, all you have to do is
cut out a piece of the cone, cover a little bit of the edge of the piece
you cut out with duct tape (for a release agent) tape it in place on the
outside, and lay-up a couple of strips of fiberglass on top of the joint
(on the inside of the cone). Let it cure a couple of hours and pop the
panel out before it bonds too good and let the "flange" you just made
cure all the way. Use tinnerman nuts in the fiberglass flange (or
nutplates, bonded to the back side of the flange and use stainless steel
screws through the panel and viola!

========================
If the Kolb is rated at 4.4 G's it will cary its gross weight X 4 which I
think is in excess of a couple of tones. In other words they may have
exceeded the margin of 4 g's at gross that was designed at the factory, but
were still well within the stractural strangth of the wings. Now if they
were to do aerobatics its likely they would not be here. I am more impressed
with that power to weight ratio being able to hoist those two adults. :-)

=============================
Well you need to define *right*. Simply casting doubts does not lend itself
to an intelligent analysis.
In terms of overloading you need to keep in mind the built in margin. If an
aircraft is rated for 4-5 g's ultimate then you can multiply the GW by the
g's and then you would know when something will break. However its very hard
in normal flight to ever get close to 3 g's let alone 4.4 (or whatever it is
it was tested to).

Jeremy - Mine is a Mark III Classic, Matco brakes. The brake cylinders are
about 3/4ths behind the cage rear bottom curved hoop where you attach the
bottom fabric. With the nosecone installed, the inspection ring is
installed so that the forward most part of the ring is about an inch behind
the rear edge of the nosecone. This only gives me access to the rear
cylinder fittings from the bottom, and with the removable inspection plates
above the cylinders, I have top access to the forward fittings, and top and
bottom access to the rear fittings. Hope that makes it clear. Bill

At the most recent TNK London gathering I asked what about the possibility being
tail heavy in my Mk3/912, w/ 20 gal of fuel, 150 Lbs of me and a full-swivel
tail wheel. The two suggestions I received both avoided the adding major weight
to the nose which adds to the total weight and chips away at performance.
1/ Put a fat cushion at the back of the seat to move my weight forward. I have
done this to all four of my Kolbs with a square life preserver cushion. It works
for me because my legs can reach the peddles and Florida has a lot of water.
The peddle adjustments could be changed to suit most pilots.
2/ Move the battery from the design location behind the passenger seat to the nose
cone (Minor increase incurred by extending the battery cables).
John H. has assured me that, with the 912 power, performance will be no problem.
I'm sure he is right but I want all I can get.

Fellow aircraft mutilators, finally got around to windscreen work today.
I laid out a slightly oversize marking on the lexan and started a cut with
the tinsnips...yechhhh. Didn't like it . Went over to the local humonguous
hardware store and found at the miraculous price of $62 a really nice
variable speed, orbital, dust blowing, headlight equipped , scrolling,
Skil jigsaw. I stuck a 12 teeth/in bosch blade in it and voila! As nice a
cut as you ever saw. (I always wanted an excuse to buy one).
This is the GE MR10 UV and mar resistant stuff, guaranteed for
10 yrs against yellowing in the sun. The label says it can be cleaned
with fantastic, windex, lysol, mr clean, pine sol, 409, top job
and a few other various solvents. -Guess I'll have to save the
peel wrap for future reference. It really is scratch resistant though,
because as I forced it , all rolled up into my little hatchback vw,
I ground the paper off against the deck latch-no scratch!
Anyway, tomorrow some drillin' to do. -BB

Don't know where you got your prices but the kit my friend purchased for
his Hawk that fit the Azusa 6" plastic wheels that was less than $300
including the single handle master cylinder. Yep, they were a snap to put
on his plane. Shouldn't be to bad on a Kolb - problems may be where the
cheap wheel barrow type wheels have been used. May still even work since
old Azusa brake drums were bolted to the wheels. The install on the Azusa
wheels you remove the existing bolts that hold the halves of the wheel
together and replace them with new bolts that have stud sticking out from
what would be the head. It catches into a slotted disc which is connected
to the disc rotor. Makes changing a wheel a snap unlike the Hegar design.

If you had enough power to get off the ground, you would have a very
marginal rate of climb. I got a few hours in a N3-Pup with a Global engine
(like 1/2 VW), if we got 150 ft min. climb we considered that to be in nose
bleed territory. If your trying to stay with minimum engine a good over
hauled 377 with CDI ignition upgrade would do nicely.
The only feasible option for a 4-stroke I've seen out side of the HKS is
the engine some of the old Team aircraft guys were putting together. It
looked good and the engine it's based on has the reputation of being
tough. (Citron (sp) from France if I recall right) The only problem last
I knew was they haven't really proven it with any adequate amount of test
stand or flight time. Next issue was parts - lack of sources in US if they
were to abandon the product. The weight looked good, might of been based
upon a belt or gear box reduction unit with electric start. I and my
hangar mate were quite interested in it but it the developers seemed to
have lost their momentum just as things were looking promising. Too
bad. See info on it at the link below.

Hi Paul here. Glad to be able to offer a tip for you folks! Being a biker
for many years and dealing with lexan windshields,facesheilds, and huge
Mississippi bugs, I can truly offer a great fix for cleaning lexan. Go to
your local motorcycle dealership, and ask for a green lexan cleaning cloth.
sorry cant remember the name brand but they will know what your after. The
material is sorta like a wash cloth treated with a built in solvent that is
activated with clean water! it will remove bug guts and will not distort the
view of the lexan. For helpers it's a jap rag as we call em. hope ya can
find them if not let me know and I will find the mfg. for you.

JD,
I used too much poetic license when I used the term "top off" !! I use
ZepRep's technique to refill, do it every few months, but still wonder where
all that fluid goes! (cant find the leak). I get about 4" of air in the
lines at each wheel over about 4 months.
I would love to slide those wheels on the grass locked up.... but it doesnt
count toward braking efficiency when the Firestar's nose is tilted down and
dragging along the ground on a landing!!!!! Gotta be gentle with those
brakes.... more than enough strength!

goodmorning... One of the most taken for granted parts of an airplane
are the lift struts..and one of the most important as far as stress. Most
planes are overbuilt in this area, including Kolbs, until rust or hidden
damage take their toll. The lift struts on my mkIII are strong enough
ok, but HEAVY. If I change anything in the future it will be to weld
up some nice aircraft streamlined tubing with integral end fittings.
-An adjust feature would be nice too.
When I bought my damaged cage from Ron Carrol (wonder
whatever happened to him?) the left gear tube was folded back/
torn away and the lift carry-through tube had separated right where
the two little diagonal braces attach at the middle. That is the
weakest spot in the whole lift assembly. The welds at the center
create a heat-affected area. Rather than reweld a whole new tube
in, it was easier and stronger to use an outer sleeve repair right
at this spot . -Better than new. But the moral of the story is,
if you have any questions with bent gear/hard landings, look
closely at this spot-even to the point of removing paint that could
be hiding damage. -BB

Hey Jerry B, I also have flown the N3 Pup with short wings and the Global and
agree wholeheartedly that it was (by Kolb standards) underpowered....barely
skimmed over the trees and houses at the end of the runway on the first
flight. However, the person I ferried that N3 for, destroyed it later, and
bought another one with another version of the 1/2 VW and longer wings and he
gets off in almost the same distance my 447 Kolb does.
No one was more surprised than me....dunno the rated horsepower but the prop
is better matched (as directed by Morrey Hummel) and the pilot is 165#...I
was 190# at the time. The prop matching on that little engine is unbelievably
important....ya gotta git over3150 RPM, that much I do know. Well that little
airplane has the appearance of crumpled aluminum foil right now but the new
one is performing beautifully with the 1/2 VW that is NOT the Global. Somehow
the Global is wanting of HP.

As the Owner/Builder of the only flying Kolbra I am compelled to answer
parts of your posting. I do not know who designed or did design testing of
the Kolbra so I can't blame or thank any particular person. Because your
model of aircraft specification indicates a particular number, you cannot
assume that the other models will use the same number. If you unilaterally
do anything in aviation the outcome is severe so I don't do anything
unilaterally. I do not have a BRS. My Empty Weight is 576 lbs. @ 55.97%
MAC, Useful load is 524 lbs.
Since our aircraft are "Experimental" or "Ultralight," few of the FAA Parts
apply to us as to structural requirements. FAA Part 23 is for certified
airplanes and the information is still pertinent to us for safety. Since I
don't have access to the design specifications or the structural analysis,
I get my guidance from AC65-9A. When I talk about c.g, weight and balance,
and specifications, I have included in CAPS what TNK has provided.
Weight and balance data can be obtained from the following sources:
The aircraft specifications. TNK BROCHURE
The aircraft operating limitations. TNK BROCHURE and my flight testing
The aircraft flight manual. What I determined to write.
The aircraft weight and balance report. What I determined and
calculated.
So that we are talking about the same things, the following Terminology must
be understood:
*The Datum: imaginary vertical plane from which all horizontal measurements
are taken for balance purposes.
-LEADING EDGE OF WING
*The Arm: the horizontal distance that an item of equipment is located from
the datum.
-Actual measurements.
*The Moment: the product of a weight multiplied by its arm.
-My calculations.
*Center of Gravity: a point which the nose-heavy and tail-heavy moments are
exactly equal in magnitude.
-My calculations.
*Maximum Weight: the maximum authorized weight of the aircraft and its
contents, and is indicated in the specifications. For many aircraft there
are variations to the maximum allowable weight, depending on the purpose and
conditions.
-TNK BROCHURE (1000 lbs normal, 1100 lbs maximum)
*Empty Weight: includes all operating equipment that has a fixed location
and is actually installed in the aircraft.
-My actual weighing.
*Useful Load: is determined by subtracting the empty weight from the maximum
allowable gross weight.
My calculation.
*Empty Weight Center of Gravity: the c.g. of an aircraft in its empty weight
condition.
-Not provided.
*Empty Weight Center of Gravity Range:
-Not provided.
*Operating Center of Gravity Range: the distance between the forward and
rearward c.g. limits indicated in the pertinent Aircraft Specifications or
Type Certificate Data Sheets. These limits, determined at the time of design
and manufacture, are the extreme loaded c.g. positions allowable within the
applicable regulations controlling the design of the aircraft. These limits
are shown in either percent MAC (mean aerodynamic chord) or inches from the

You can see from the information that there is several areas that can be
improved on, ie., Manufacturer Aircraft Specifications, Manufacturer and
Design Aircraft Limitations and published envelopes. Since there is no such
thing as "recommended gross weight", we have to use the information
available to us and tailor it to our situation to cover the most extreme
situation we could imagine flying at. Remember that the Gross Weight on the
aircraft placard is the weight that corresponds to that extreme condition.
What some people interpret as a "Cavalier attitude" others could interpret
as that person having more knowledge or experience in that area and the
other person not taking the time to gain that knowledge or experience. If
1200 lbs is on the aircraft placard, then it is not overloaded until it
exceeds 1200 lbs. My 1100 lbs number was published by TNK and is on my
placard and no I will not exceed it.

Sorry, I had to resend this message. I forgot the links to TNK Brochure in
the first send.
As the Owner/Builder of the only flying Kolbra I am compelled to answer
parts of your posting. I do not know who designed or did design testing of
the Kolbra so I can't blame or thank any particular person. Because your
model of aircraft specification indicates a particular number, you cannot
assume that the other models will use the same number. If you unilaterally
do anything in aviation the outcome is severe so I don't do anything
unilaterally. I do not have a BRS. My Empty Weight is 576 lbs. @ 55.97%
MAC, Useful load is 524 lbs.
Since our aircraft are "Experimental" or "Ultralight," few of the FAA Parts
apply to us as to structural requirements. FAA Part 23 is for certified
airplanes and the information is still pertinent to us for safety. Since I
don't have access to the design specifications or the structural analysis,
I get my guidance from AC65-9A. When I talk about c.g, weight and balance,
and specifications, I have included in CAPS what TNK has provided.
Weight and balance data can be obtained from the following sources:
The aircraft specifications. TNK BROCHURE
(http://home.attbi.com/~kolbrapilot/KolbraWB.JPG)
The aircraft operating limitations. TNK BROCHURE
(http://home.attbi.com/~kolbrapilot/KolbraWB.JPG) and my flight testing
The aircraft flight manual. What I determined to write.
The aircraft weight and balance report. What I determined and
calculated.
So that we are talking about the same things, the following Terminology must
be understood:
*The Datum: imaginary vertical plane from which all horizontal measurements
are taken for balance purposes.
-LEADING EDGE OF WING
*The Arm: the horizontal distance that an item of equipment is located from
the datum.
-Actual measurements.
*The Moment: the product of a weight multiplied by its arm.
-My calculations.
*Center of Gravity: a point which the nose-heavy and tail-heavy moments are
exactly equal in magnitude.
-My calculations.
*Maximum Weight: the maximum authorized weight of the aircraft and its
contents, and is indicated in the specifications. For many aircraft there
are variations to the maximum allowable weight, depending on the purpose and
conditions.
-TNK BROCHURE (1000 lbs normal, 1100 lbs maximum)
(http://home.attbi.com/~kolbrapilot/KolbraWB.JPG)
*Empty Weight: includes all operating equipment that has a fixed location
and is actually installed in the aircraft.
-My actual weighing.
*Useful Load: is determined by subtracting the empty weight from the maximum
allowable gross weight.
My calculation.
*Empty Weight Center of Gravity: the c.g. of an aircraft in its empty weight
condition.
-Not provided.
*Empty Weight Center of Gravity Range:
-Not provided.
*Operating Center of Gravity Range: the distance between the forward and
rearward c.g. limits indicated in the pertinent Aircraft Specifications or
Type Certificate Data Sheets. These limits, determined at the time of design
and manufacture, are the extreme loaded c.g. positions allowable within the
applicable regulations controlling the design of the aircraft. These limits
are shown in either percent MAC (mean aerodynamic chord) or inches from the
datum of the aircraft.

Yep, weight makes a big difference on that airplane. The owner let another

better with him but its still marginal, no reserve that's for sure. I

This brings up a question that I have been wanting to ask? I notice that
many of the BRS systems that are mounted in Kolb aircraft are inboard,
behind the fabric covering. Has this mounting placement been tested? will
the chute penetrate the outer skin? and if so what about entanglement with
the prop/tailfeathers/wings. The ones that look more promising as a life
saver are mounted on top. Pointing upwards. I'm new here so go easy.
Otherwise Expect No Mercy!

This incident shows that the chute has worked in that model one time and
included that it had not worked one other time. Both incidents the
occupants had only minor or no injuries. What is missing is what panel came
off the wing and why (still to be released information) or what caused the
other incident.
I think that not having a chute makes one fly more conservative and not take
that extra chance.

John/gents:
This incident/Acident was caused by maintenance screw up. Bolt/fastener came
out of one end of aileron rendering it useless and pointing the wrong way.
No evidence of safety wire. Here's the NTSB report:
http://www.ntsb.gov/ntsb/brief.asp?ev_id=20021008X05290&key=1
Made a living jumping out of airplanes in the Army, have two saves with a
Jim Handbury hand deployed parachute, both caused by material failures. The
first was factory's fault and the second was my fault. Either way it saved
my ass twice.
The last one was in March 1990. I modified my flying style, built the Mark
III, still fly with a ballistic recovery system, and I thank God every
morning when I get up and every night when I go to bed for giving me another
chance at life.

This safety issue is hard to get a handle on . If anyone on this list
was not a bit "adventurous" they certainly would not be interested in flying
ultralights or experimentals. Every time you fly it is a calculated risk. Calculated
is the key word because we all calculate differently. I am not trying
to change any ones opinion but just merely point out that we all calculate differently.
I have known some very good pilots that are not here with us anymore.
And on the other hand , I know some very poor ones that are still flying.....go
figure. Some of the greatest pilots have died in very unusul ways, pilot error
or mechanical malfunctions...
For me flying is worth the risk that I accept.

Morning Ed/Gang:
Amen!
I have made a lot of mistakes during my short life time. Hopefully, that is
how I learn. I know some circumstances have reinforced the learning curve
and hopefully, I won't have to repeat them.
If flying was not an exciting, adrenulen pumping hobby, I wouldn't be
interested in it. Ultralights and light planes, that I build in my
basement, add to the interest and excitement of flying. I am responsible
for all, what is good as well as what is not so good.
I feel much more comfortable flying than any day driving on US 231S or in
the traffic of Wetumpka or Montgomery, Alabama, especially the rural roads
up here in the woods where I live.
Don't think I will ever fly a perfectly safe airplane in a perfectly safe
environment, especially mine, but who wants to.

Ed and others,
The way I look at it, ultralight (fat ultralights) and light aircraft are
much safer than GA. Why? Speed kills. The faster one moves through the
air (or on the ground), the more risk that is taken. The light plane has
low kinetic impact forces and a lot of built-in drag which are both
safety factors. I have witnessed some terrific ultralight accidents over
the years and most have walked away.
I watched one guy pile in his 2-seat Quicksilver straight into the ground
from 100'. His body bounced upwards on impact and I thought he was dead.
I ran over to him and he gets out with a smirk on his face.
Another one was a friend that hit a high voltage powerline at 60 mph. The
line snapped and his plane came tumbling to the ground (actually ice, as
it was during the winter out on the frozen lake in northern Minnesota).
He told me that he waited for the crackling of the electricity to stop as
the line was wrapped around the wing and tail before he hopped out
completely unscathed. We both dragged his plane off the lake that
afternoon.
Another guy had crashed his ultralight on 5 different occasions, one time
so severely that the engine came off and rolled across the field. This
guy was a licensed GA pilot that flew a Pitts Special. He eventually gave
up light plane flying and strictly flew the Pitts. He died in his sleep
of an apparent heart attack.
If one thinks of all the auto accidents that happen every day, flying a
light aircraft is almost like taking a walk in the park. Sure it's a
calculated risk, BUT so is getting off the couch and walking outside.
Speaking of which, I had a friend who's father died as he was getting
into his truck one morning. He slipped backwards on some ice and hit the
back of his head.
Life is a risk ......

jerb
cant tell you about the powerfin but i can give you a
comparison between the precision prop and the warp...
buy the warp....
to be honest it is not an apple to apple comparison as i did
some fabric changes on the cage at the same time i changed
the prop, i also pitched the warp for better cruise.
with all the changes i went from about 76 to 92 mph.... i
can hold about 5 to 600 less rpm and still maintain the old
performance levels.
the reason i first tried the precision prop was that while
visiting my brother in washington we visited some of the
other pilots and the opinion was that the precision had
more thrust than any others.... with my experience buy
the warp.... tnx john for the info you shared with me on
this matter.

I know for a fact when a pilot thinks he knows everything and he don't stink no
more because he gets so dam arrogant he is a dead man. Cause when you quit learning
it is all over with. I spent 15 years army aviation and 14 years flying
a low performance low powered ultralight. The smart arrogant pilot over and over
and over is the one you here about died in a perfect flying airplane do to
pilot error. There names never end in christ,Mahommed,or Budda cause you can
hear '' there no it all attitude when they get close". And they are dangerous.

Hey Jerb and All,
Just finished my test flights with the inflight electric Ivo props, both the
3 blade ultralight and 2 and 3 blade medium models and compared them to my
existing 68" 3 blade PowerFin - F.
These test were on my fourstroke BMW with a Rotax C gearbox 3:1. about 70
hp.
I made a chart plotting the rpm. and speed to get a real feel for comparison
of efficiency.
The PowerFin is the most efficient, but only by a small margin and is not
inflight adjustable unless you want to spend $2,800.-
The Ivo 68" 3 blade ultralight prop is surprisingly close to the PowerFin
and only $860.- for inflight adjustable. But most important, it is
absolutely smooooth... at all rpm's.
Next I tried the Ivo Medium 2 blade hoping for more efficiency with the
wider blade, but it was not, almost identical, but a lot more vibrations, to
the point where it was uncomfortable.
The Ivo Medium 3 blade was definitely smoother, but not as smooth as the
ultralight model and about the same efficiency.
The clear winner for my situation is the Ivo ultralight 68" 3 blade inflight
adjustable.
Now I can actually get to 84 mph at 5200 rpm. and cruise very nice at 4800
rpm at 76 mph. and burn 3 gallons per hour.
Between Climb pitch and Cruise pitch I see a 26 mph increase in speed....
It is like adding another gear.
All this testing was done at 850 LB gross weight in my Mark III Xtra.
The inflight adjustable prop really makes sense with a fourstroke engine,
unless you have 100 hp and power to burn.

Great Post John!!!
I want to throw in another tidbit for those that are fretting nervously
about the Gross weight thing (justified fretting or not...I'm not
judging...)
Another thing that affects the "gross weight" of an airplane has nothing
to do with the strength of the design at all. A very important
specification is "power loading" Just looking at the Mark 3 for
instance... It was originally flown with a 503 (and I remember Dan
Johnson saying that it was very adequately powered with that
engine...wonder what he would say about a 912S powered one???) Anyway,
a given airframe with a 503 might be doing well to climb out at 200 fpm
at 800# while at 900# it would be a sure bet to crash in to the tree
tops at the end of the runway. The same airframe with a 65hp 582 or a
912 powered version would have no problem at 900-1000#. Point being
strength of the airframe is not the only point.
Look at Skystar (the KitFox people) Their model 4 Kitfox lists a 1200#
GW except for when powered by a 503, when they limit the GW to 1050#.
It's not an airframe strength issue at all, it's an engine "strength"
issue.
I don't know what the limiting factors were in any of the Kolb designs,
airframe or power, just throwing this in to muddy the water some more.

Dear Kolbers,
I've been 'unsubscribed' for the last couple years, finishing-up and then
enjoying my modified Twinstar. If anyone is interested, I put some images
up at:
http://gbronline.com/froghair/TSpix/index.html
Sorry, the page will take some time to load unless you're on broad-brand...
Details:
1984 Kolb Twinstar.
Rotax 503 SCSI w/'B' Gearbox.
Warp drive 2-blade prop.
Cruise @ 5400rpm - 55 mph true.
Completed & taxi-tested 9/13/01 (2 days after the world changed, impeccable
timing as usual...). Crow-hopped & flew a pattern or eight or twelve on
9/15/01 (after GA suspension lifted). Have put 80+ hours on the Hobbs to
date and love it although I was hoping for 60 or better cruise (always the
optimist...). Cockpit enclosure copied loosely from Mark II.
Thanks to the 'old-timers' on the list for all your support! I'll probably
un-subscribe again shortly - just hard to find the time - but will be
lurking through the archives.

It may take a lot longer than a year for the aluminum to rust. If you
are real worried about it paint all the steel parts you can see with white
paint. Rust shows through white real good. After a year if you do not see
any brown streaks coming off the steel parts you are probably okay. Perhaps
squirt some wd 40 into the tail fabric through small vent holes in the
fabric. These holes can be made easily with a soldering iron.

Understand that I don't want to start a flame war BUUUUUUUUUUT, you did buy
a motor and pay for the covering and paint etc. Payed for the insurance and
I'm sorry you guy's get screwed on the money conversion. But as far as I'm
concerned the cost of flying is the cost of buying all of the equipment.
Remember you bought a engine gauge why, have that compass? I just don't

Woody/Gang:
What about the inside of all those 4130 chromoly steel tubes?
4130 rust by looking at it.
I have used tube seal on all three of my Kolbs. Never, to the best of my
knowledge, heard of anyone else going to the trouble prep'ing the steel
fuselage and other tubular steel parts.
Do not take it for granted that your factory or otherwise welded steel tube
fuselage/parts are sealed airtight. There's pin holes in all those welds.
Tube seal will find them in a short period of time.
I bought a qt of Stitts (now Polyfiber) tube seal in 1984. Have done my
three airplanes with it. Some of them more than once. Still have enough
left for a half dozen more airplanes.
I have had the opportunity to see what happens to 4130 on the inside when
not prep'ed with tube seal. It ain't purty. Certainly got my attention.
And these were airframes that had not been swimming in a Georgia lake of
submerged in a hanger for a week.
Just cause you can't see it does not mean it ain't there. Rust to 4130 is
just like termites to pine in Alabama.
Take care,

BTW: A balistic recovery system or hand deployed parachute is only as good

survivable fatal crashes when the system was not activated. One must
indoctrinate himself, train/practice what he is going to do if the need
should arise. There will normally be no time to sit there and contemplate
what the next move is to be or be so horrified, as the result of an

Hello list members.
My feeling towards the chute is that it gives me more security for that one
moment "if" something happens I am insured.
We do buy insurance for dead things, and then life insurance for us (me),
but then I am dead. It helps my wife and children, but how about me? I would
like to get some of the insurance money back, to repair for the life, just
like you would do with the dead part you insure, like the house, car and
such. Something to compensate for the dead thing you lost.
I know insurance can be costly, but life is too good, and too short to take
that chance, if you have other options like a chute.
Just my opinion. Flame away.
Best wishes.

I'm passing this own as more food for thought...take it however you
wish...Like has been said already, the whole chute issue is like
Ford/Chevy.
(Before anyone thinks it...the "mystery person" is NOT me... ;-)...)
A fellow I know had(?) to deploy a BRS about a month ago due to the king
of all pilot errors...fuel starvation. Now I know the first 2 things
that everyone will say...
1. "That was DUMB!!! I'll never do that!!! He was (insert expletive
here...dumb, careless,...distracted maybe?) Well my answer is this...I
pray that your right...but are you? Go read the NTSB archives about all
the retractable-gear pilots who have landed with the wheels comfortably
up in the wells. There is a saying around Long-EZ pilots that there are
those that HAVE landed with the nose wheel retracted, and there are
those that WILL. Fact is if you do anything long enough, you'll
screw-up. Its part of that list of absolutes in the universe that is
better known as "Murphy's Law". Like the saying goes, "Never say
Never."
2. And I've already heard this one several times since this
incident..."I'd never pull the chute just cause the engine quit!!! I
want to be a "pilot" all the way to the ground...not a passenger. Well
boys and girls, this man is alive today because he pulled the handle.
There was nowhere to go and nothing but 75'+ Southern Pine trees for as
far as the plane could glide. Now I know nobody gets out of gliding
range of a safe landing spot because we are all perfect pilots in a
perfect world. This particular case he got too low on final approach
into a 4000' paved runway at a Class D airport, and when the engine
quit...he sized up the situation, said "Oh well", and give the red
handle a mighty pull.
YES, it was a series of bad judgments that put the guy in the position
to NEED to pull it, but when he needed that one last option to save his
butt, it was there and he drove home that night to a wife and 2 kids
that were glad to see HIM and not the "county sheriff" coming to deliver
the news.
Now the end to this story is interesting. The chute deployed fine at
about 100' above the trees and the plane lowered between 2 large trees.
The smallest tips of the limbs of these trees were probably 15' apart
and the plane rung the hole. It lowered through the hole until the
canopy hung up in the top of the trees and stopped the descent. When
the plane stopped the nose wheel was about 2 feet off the ground. He
unbuckled the seat belt and hopped out...and promptly threw-up. The
wingtip bows were bent in the descent, so the wings will need a recover,
but other than that, the plane was unscratched.
This all happened right at dark about 1/4 mile off the end of a fairly
busy airport. Airport buddies got the plane out of the woods at first
light the next morning and pulled the parachute canopy out of the trees
before it was spotted...and everyone involved decided that what the FAA
and the airport authority didn't know, wouldn't hurt them...
And everyone... LIVED... happily ever after...

Something I find fascinating in this whole discussion on chutes is that no
one has mentioned the "spouse factor." The fact that I have a chute on my
MKIII makes my wife a lot more comfortable flying with me. I think my
MKIII is perfectly safe without a chute, (although when I am flying up to
Chestnut Knolls, there is about 20 miles of no place to land in the event
of an engine out, and having a chute lower me into the never ending trees
is probably a better option than trying to slow flight into the treetops,
but I digress.)
How many pilots in little single or two place airplanes are comforting
their spouse because they have a chute on board? Maybe it is subjective,
maybe you will never use it, maybe there is a situation where it will do
more harm than good. Who Knows? But if you are out poking holes in the air,
and the spouse at home is in a more settled frame of mind because you have
a chute....small price to pay.

Ken, I agree with you 100% !! As a matter of fact, the singular thing that
makes ULing "safe enough" for me is the advent of the BRS. Something that
planes didn't have before ultralighting. Who ever heard of the parachute
bringing down both you and the plane!! Sure kills the idea of jumping out of
a perfectly good airplane, doesn't it? And, indeed, our craft are NOT
certified like the very expensive GW craft are. Sure there really is LESS
reason for certification as the craft are simpler, fly slower and have very
little to hide. True, but the question as you have stated begs the
asking....why NOT have a chute?

either, but they had good reason...... in their minds anyway.... it would be
sissyfied. Many died needlessly, but for a good cause, they proved they
WEREN'T a sissy ....kinda similar to the folk from the terrorist camps that

Ralph / Listers,
Here's a Minnesota deployment for you Ralph.
Not directly Kolb related , just something to think about.
Date: July 6, 2002
Location: Rural Lake Park, MN
Air: 83degrees
Wind: Calm
Aircraft Type: Tierra II w/503 rotax
Occupants: 1(Pilot) no passengers
Altitude: 250ft
Problem: Elevator push/pull tube disconnected at elevator.
The engine was at high power when the elevator push/pull tube broke,
changing power settings would change his pitch attitude but would not pull
up out of a dive if he would have allowed it to get to that point. I
believe, and so did the pilot, that this was an emergency and his only
chance, given the wooded area he lives in, was his BRS. (In his words)"I
Killed the power, popped the chute and braced for a rough landing"." Thank
God I had the BRS". This was his second forced landing. His first was a
water landing after sudden engine failure( no it's not on floats). After
that his wife insisted he get the BRS. At the time he didn't think he would
ever need it, and really had a tough time with the price, he felt it was
allot of money for something he would never need. Made a believer out of
him.

I have a King KLX100, its a GPS/Comm that I find is real nice to have in

display button and all the frequencies for all the local airports is
displayed. I select the desired frequency and talk. It also has a
emergency feature were I hit two buttons and confirm then a pre recorded
emergency message is transmitted along with the exact GPS location. I'm

From: | ul15rhb(at)juno.com |
Thanks Guy for this post, I was wrong. You have proven there has been a
chute deployment in this state (MN).
By the way, the guy that I talked about that piled his 2-seat Quicksilver
straight into the ground from 100' that had a smirk on his face, also had
a BRS onboard. He survived just fine and is still flying today. This is
not to say that everyone would be so lucky.
I suffered a prop failure in '91 (Culver wood prop) that took out a third
of the inboard left aileron of my Firestar. I was able to glide my
crippled plane to the ground (actually ice, as it was on a frozen lake)
and made a very soft landing that I will never forget.
Last fall, a year ago, I struck a hawk that dented the left wing again on
the last outboard rib. The plane had a serious vibration problem and
right rudder was needed to compensate for drag on the left side. I did
not know the extent of the damage until I had flown 38 miles home. There
was a 1 inch dent in the middle straight section of the rib, and the
fabric was caved in on that side that created the drag.
If I had a BRS, I might have used it in both of these situations. As it
was, I lucked out and am still flying the same Firestar to this day. Am I
stupid or do I have a death wish? No.
My reasoning is this:
"As long as I fully understand what happened in both of these situations
and can correct it (ie: use a composite prop and avoid birds as much as
possible), I do not have a safety issue. It's when I don't understand
something that could be the real danger."
Again, this is not an anti-BRS post. I felt as long as we were on this
topic, I might tell you guys my own experiences flying my Kolb.
Oh, and then there was the encounter with a low-flying jet ...... :).
Maybe in another post.

Jerb and Others,
I had a similar problem with my Garmin 90 not wanting to lock in. I read up and
found out that the reason is that the chip calculates where the satellites should
be based on where they were the last time you use it. If I have not been
flying in a while, I set my Garmin out on the hood of the pickup and turn it
on. By the time I get the FireFly out of the hangar and ready to fly, the gps
is locked in. Initially I turn it off so that I can use the radio without interference,
but when I get away from the airport I can turn the gps on and it
locks in in a minute or so at most.
I hope this helps.

Hans and others,
In part, it depends on what type of lift struts that are on the plane.
For 13 years I flew with riveted round struts on the Firestar and they
vibrated at 3000 rpm and at idle. I made new streamlined struts with the
extruded material and they are quite a few pounds heavier but they do not
vibrate at any rpm.
I trusted my life to those 25 rivets at each end on those round struts,
and was always looking at them, while on approach, when I throttled back.
It didn't give me a warm fuzzy feeling watching them vibrate the way they
did.

===============================
Some years ago I got curious about those ANC headsets, and bought a pair
with the expectation that they will not live up to the hype and i'll send
them back within the 30 MBG. I now own two. :-)
The set that I use daily is my old David Clark's -60, which started life as
just plain old passive set. I sent them to that mod outfit in Texas called
Headsets inc (I think they have a site). They came back as good as any
factory ANC set I have tested. I preserved my original investment by doing
that. My other set is Lightspeed M-20 or some such. They are too pretty to
use. However when I am done with my build the D/C set will go into the M3X
and the fency Lightspeed will go into the Beech.
I need to add that I have as yet not flown any of them next to a screaming
2cycle motor, so I don't know how well they'll do. But I am curious.

Ron/Gents:
Got a set of Litespeed 25's for Xmas. Couldn't wait to fly
with them in the Mark III. Wore them around the house
making noises to see how well they performed. Great! Got
in the Mark III, fired it up, put on the Litespeeds. Worked
great. Taxied out, performed mag check, takeoff check, and
they still worked great. Took off, and immediately started
getting feedback throught the headset. It was real quiet
between the WAH, WAH, WAH, WAH, droning feedback. Sent'em
back and got my money back. They did not work with a 912
and 3 blade fast taper Warp Drive prop, and enclosed
cockpit. I do not know how they would work with a two
stroke. I think there are some people on the Kolb List
flying with them though.
Would like to get another set that was tuned for my type
noise and environment. Would be nice to fly in a quiet
environment.
Take care,

Dwight/Gang:
I'm not Ralph, but I also went to streamline struts on my
Firestar for the same reason. Did not like looking out
there at them vibrating like a guitar string.
Saved up my pennies (and a lot of dollars), ordered some
4130 streamline tubing (forget the dimensions), took my old
round lift struts down to my brother Jim's, fabricated steel
streamlined lift struts. While he was at it, Jim welded
some bushing stock in the end fittings so I could bolt the
lift struts snug and prevent vibration from enlarging the
holes.
Result was vibration went away and performance increased,
especially power off on approach to my little 600 ft
airstrip.
The new streamlined lift struts were worth the time and
money involved to fabricate.

Dwight and others,
Actually the streamlined struts were already built for a late model
Firestar with 5/16" pins, and had to modify them for my Original with
1/4" pins. So I ended up cutting off 3" on each strut and drilling new
holes. I bought 4 new end fittings at $20 apiece, from TNK, to fit the
1/4" clevis pins in the tangs. I thought about drilling out to 5/16"
(with the new end fittings) but the 1/4" pins do no wear and are plenty
strong enough (as I recall, there may have been an edge distance problem
at the bottom of the cage). To match up the lengths, I put both types of
struts side by side and placed a long 1/4" bolt through each end of the
drilled fittings. It took me a weekend to retrofit them for my Firestar.
The new streamlined struts cut drag and I gained about 5 mph in top end,
but added 7 lbs in weight to my already fat ultralight. They give me more
piece of mind (3 bolts at each end) rather than depending on 25 rivets to
hold my fat 200 lbs up in the air (although each rivet has a shear
strength of 250 lbs, it really is plenty strong and Homer Kolb still did
it right). Four years ago, I made a lexan gap seal that added more
weight. Can't make 254 now, but then it never did. It's at an even 300
lbs empty.

When I bought my MKIII back in 96' , streamlined lift struts were an
option. If New Kolb no longer offeres them, try Carlson Aircraft. They sell
extruded aluminum lift struts in two different sizes, prices are
reasonable, and they will even make up end fittings if you can tell them

===========================
Geez that reminds me. :-) Yes my first set of the m-20 did the same thing.
I also sent it back. At the time I was a member of AVSIG on Compuserve and
one of the owners, or big cheeze whatever.. was participating online. Anyway
after I made my comments known online, he sent me some private mail
suggesting that I change that headset to another with different ear
cushions,, that they apparently do not offer to the public,, or so he
said... I said ok. Those worked and I still have them. It has to do with
noise penetrating the ear cup and causing feed back with the ANR circuitry.
However the best ones I ever tried were the Telex 4100. I sent them back
because I thought the factory David Clarks were better. Were I to do that
again I would have kept the Telex ANR 4100, and ignored the rest. I don't
think the Telex ANR 4100 are still in production but I think they have a set
that evolved from those. As long as they have a 30 day MBG its worth
checking out.
Mu suggestion to anyone that has a good quality set of headsets would be to
either get the ANR kit from Headsets inc and install it yourself, or sent
that to them and have them install it for you.

Lar/Gents:
The 4130 streamline struts give the aircraft a more solid
feel. I feel more comfortable with them. However, after
beginning life with 4130 streamline lift struts, of which
one got totaled after 30 minutes, Miss P'fer ended up is
.058 4130 round tubing with the extruded alum streamline
tubing slipped over the round steel. These act as fairing
only. Was cheaper than trying to replace with 4130, since I
already had them with the Mark III kit.
I can not remember if I oriented strut with line of flight
or bottom of wing. I may have lined them up with the
fuselage. I don't think you will ever know the difference.
Take care,

Lar,
I set mine so the fitting was inline with strut chord. In cruise, this is
parallel with the bottom of the wing and probably wasn't the best angle
for minimum drag unless I'm cruising very fast with AOA zero with the
horizon. At a lower cruise speed (55-60 mph), it will offset the weight
of the struts. Everything is a tradeoff.

Subject: | Measuring Best Rate of Climb and Best Angle of Climb |
There was a question on measuring the best rate of climb and angle of climb.
Sorry, I lost the message before replying as I intended. So, he is my reply
to what I think the question was.
The FAA publishes a circular labeled AC 90-89a which can be found on the
internet at:
http://av-info.faa.gov/dst/amateur/ac90-89a.pdf
Page 47 and 48 (shows as page 54 and 55 of the pdf document) show how to
measure the best rate of climb and best angle of climb.
BTW, AC 90-89a is the FAA's view of how to flight test your new ultralight
or homebuilt aircraft for any who may not have found this circular and are
thinking of testing their new plane.

I have thought about this for my Twinstar. I may get a length of
aluminum 8" wide and have a sheet metal shop bend the edges so that they
slip together like a stove pipe section. Then start a 1/2"radius bend in
the middle. I should then be able to fold them over and then slip them onto
the round struts. I would try bonding the rear edge. If I don't go to a
metal shop bonding and then adding a few rivits should be strong enough. I
could then attach them with 4 rivits like Kolbs plastic struts.

The first U/L I ever had that actually flew worth beans was an Easy Riser.
It had streamlined struts that were very simple and light weight, using
aluminum cuffs that fit along the rear side of all the tubes.
All the struts connecting everything were 1" round tubing. They were
streamlined by taking aluminum sheets about 5" wide and the length of the
struts, and folding them over on themselves with a brake, making a cuff
that was shaped like the back half of a streamlined fairing.
Along the open edges, there was a further slight bend put in lengthwise
about 1/4" back from the open edge, bending toward each other. These cuffs
were slid onto the tubes from the back, and secured with a 1/8" rivit at
each of the four end corners, and then the front half of the tube was
covered with aluminum tape wrapped around the front and overlapping onto
the cuff. The little bends along the open edges conformed to the curve of
the tubing.
Years later I tried the same thing with aluminum flashing, bent it in my
Black & Decker workbench, and taped them onto all the struts on my Hummer,
no rivits. Picked up several miles per hour top end.
The aluminum tape does not hold up well when exposed to any weather, and is
a bear to peel off when you go to replace it after you leave it on too
long, but if any of you feel like experimenting, here is a way to do it
while you decide where to drill the holes in your good stuff.

because the airfoil is not stable at the pivot point that is imposed by the
round tube underneath. there isn't a weathervaneing force because there is
as much area in front of the pivot point as behind. with no stability it is
a bad idea to let it spin free cause it might just spin.
this is serious by the way, do not try it, you might not live through the
experiment.
