John/Don/Everyone,
Thanks for the discussion and explanation of how you
got there. I take full responsibility for the final
design and configuration of my plane, but having you
folks share your reasoning for the mods you did gives
me valuable insights. I try to take full advantage of
every lesson others had to learn the hard way ;-)
Has anyone tried a jury strut with clevis pins or some
other quick disconnect fitting to allow wing folding?
Don, great website shots. I had focused so much on
the tools and techniques pages, I missed these. Any
of you guys have other photos of this stuff? Do not

Good report.
I guess I'll revisit the wings when I am done with the
cage and before engine mounting.
I did'nt get the impression that my M3X wing was
lacking for strength.
Hi Ron/All,
I'm not trying to give the impression the wings need
attention; only because I am doing non-standard
weights am I looking at this stuff. But I agree with
you, It's always worth another look. Do not archive

> Beauford
Beauford/All:
I have spun all three of my Kolbs:
Ultrastar
Original Firestar
MKIII
All three spin and recover instantaneously.
The Ultrastar spins like a Cessna 152 without all the
altitude loss.
The Firestar would spin 1/2 turn with stick back to the
stop, full right or left rudder, engine idling, and return
to flying with controls locked in that position. An engine
off spin and the FS spins up like a top with instant
recovery by relaxing the controls.
I'm sorry I can not remember altitude loss for any of the
three models for number of spins. I'll have to do some
spins in Miss P'fer to refresh my memory, but altitude loss
with her or the other two Kolbs was not much. However, would
not want to do one near the ground.
No bad habits with either of the three.
Never got into or near an inadvertent spin with any of them.
Ailerons are still in control during stalls/mushes on all three.
Instant recovery by relaxing controls on all three.
The Firestar would recover from any unusual attitude by
relaxing controls. That includes inverted, tailslides,
falling out of unsuccessful aileron rolls, screwed up hammer
heads, stalling out of loops and wing overs.
No vortex generators on any of them.
I may get around to experimenting with gap seals on rudder
and elevator, but don't have time right now to mess with that.
With well over 3,500 hours and 19+ years flying Kolbs, I
have never found any of them to have bad habits of any kind.
If they did, I probably wouldn't be flying them today.
They will stall level, near the ground, giving the pilot the
impression he is flying, but in a full stall. Nearly
impossible to push the nose over to regain flight before
impact in this configuration. Got into this situation once
with the MKIII and gravity won. Thank God I was strapped in
to a crashworthy airplane or I may have suffered more than
black and blue bruises on bottom of my thighs and loss of my
glasses on impact.
I don't think I will get involved in the experimentation
process of vortex generators. I am pleased with the
performance band of my MKIII. The airplane responds to my
commands and makes me happy the way it is configured.
From a lot of the posts I read concerning vortex generator
experimentation, the test pilots don't have enough time in
Kolbs to know how to fly them in the standard configuration,
much less experiment and change a well proven design that
has been flying for many years.
Take care,
john h
PS: Don't spin without a parachute. And don't be attempt
to be an aerobatic pilot in an airplane that is not designed
for aerobatics. Might kill ya!!!

Jim/All:
Will have to take a look at the MK III plans I have to see
if there was provision for quick release of jury strut.
I didn't like the idea of drill a hole in the lift strut to
attach hardware for jury strut, as called for in the plans.
I used 4130 strap shaped around the lift strut with the
ends bent up to form to tangs for 3/16 bolt to attach strut.
Takes but a second to undo the little nut and bolt.
On the main spar gusset, used some SS fuel tank strap to
configure the upper attach point by riveting the tang on the
gusset.
Works for me,
john h

Bob/others,
I've been planning to do the Bahamas for about three years
now and will do it within the next few years if all goes
well. I would really love to do it with others. My plan is
to visit all the airports listed in the islands camping most
of the way. My wife plans to fly down and spend a few days
along the way.
I have flown to the Bahamas before in a 172 and did not find
it a problem at all. At first I was a little nervous but
after just a few minutes of open water little islands began
to appear along with a steady stream of boats. All
nervousness went away. From what I now understand the
Bahamas Government is permitting Experimentals into their
airspace and airports.
Count me in on your planning.
Gary

It would be interesting to see a list of the variety of powerplants that
have
propelled Kolbs through the years, including the chainsaw engines.
You would have to be innovative to get much power out of the two-banger
vw. I still think that for the heavier machines, a direct drive vw could be
successful. -the first requirement would be the longest stroke available
in conjuction with the smallest (83m) bore. You want the highest
piston speed per revolution and a low ~7:1 compression ratio to approximate
a "real" airplane engine. The high piston velocity fakes the engine into
thinking it's turning a higher rpm. Check out the piston speed on a PW 985
or 7 cyl Jacobs vs crank rpm. -BB do not archive

My MKIIIc has jury struts with clevis pins. There is one clevis pin on the
wing attach end. The other end is permanently attached to the main strut but
folds flat with the main strut when disconnected for wing fold. My MKIIIc
was one of the last few that had stock jury struts before they changed to
full length tube supports in the main struts that eliminated the need for
the jury struts. The jury struts add drag and only help with negative G
limits. Ok and also when a wheel breaks off.

--> Kolb-List message posted by: "JACKIE AND DALE SELLERS" <jsel@bellsouth.net>
I have an Ultra Star that I have been rebuilding for the last year and a half.
I have flown it and it flies great. It has the Cuyuna and has a reduction drive
with four v-belts. The problem is, there is a big hex nut on the prop shaft
bearing housing that allows you to tighten and/or replace the belts. I suspect
the engine and reduction drive came off a Quicksilver but I'm not sure.
The nut requires a 1 1/2" open end wrench to loosen and the wrench can not be
made of material more than 3/16" thick which is how wide the slot is where the
nut is located.
If anyone is familiar with this type of reduction drive and might know where I
can get one, please let me know.
The Cuyuna purrs like a kitten. I have had no trouble with it. Both CHT & EGT
are well in the green. The power of the engine and the rate of climb are outstanding.
Much better than I expected. I am a private pilot, very experienced
in building and flying experimentals but this is my first ultralight. I had
no trouble on the first flight. It was alot of fun.
Thanks for your help.

John,
I know you are a Kolb purist, but this is ridiculous. If the design is so good,
why is it that you have been the one who has made the most modifications to
Kolb designs. Adding here and there and beefing here and there. You do this
as a personal choice and it is a reflection in the way you want to fly, and yet
you say that others should not do the same. Not all people are going to pull
the leading edges off both wings, and then to say it would not have happened
if there was a small change made in the rib design. Some might say that you
should not have pulled it up so hard or slowed up a little to pass through rough
air etc.
The original FireFly was a very un-fun plane to fly on short cross countries during
the middle of the day. When I quizzed the old Kolb Company about the ailerons,
the answer was that I should not try to fly the FireFly in the middle of
the day because it was an ultra light. With changes to the aileron chord and
linkages it has come from an arm breaker to a two fingers on the stick fly it
any time aircraft. VG's allow one to land it in a 20 mphi gusty cross winds,
achieve a better climb rate, and greater stability in just about any configuration.
If you try VG's on your plane, you may find you like them just like the rest of
us low time pilots and non-pilots. Don't knock them until you try them.
Have a good day and fly safer with VG's.

Jim,
Where my Mk-3 jury struts connect to the steel fitting on the wings I use
3/16 bolts with drilled shanks and castle nuts with safety rings through em.
This way on tear down you just pull the ring, spin off the castle nut and
fold the jury struts down along the wing struts. You can even put a piece of
1/2" pipe insulation over the jury struts to keep em from scratching the
struts.
Sincerely,
Denny Rowe

I found very little in the arhives except the gross wt increase.
The biggest differance is the wing spars and tail tube went from 5" to 6 "
tubing with a little thicker wall. The fuselage cage sides were lowered on
the Mk-3 and also widened a bit. The Mk-2s max recommended engine size was a
dual carb 503, while the Mk-3 can handle 912 engines.
Some folks who put 582s on Mk-2s wound up with fatigue cracks in the steel
fuselage cage. The Mk-2 is a good aircraft, but the Mk-3 is a stronger
airframe, it really is a totally new plane from a Mk-2, probably also has a
few more ribs in the wings.
Sincerely,
Dennis Rowe

Wow,
I had no idea that Kolb had eliminated the Mk-3 jury struts, I was thinking
when I built mine that it would be nice to have a full length tube inside my
struts for extra security but decided the stock streamlined tubes were
plenty strong.
What about Miss P fer John, Does she have the internal tubes and jury struts
or just the jury struts?

I can tell you the difference between a 1/2 VW and a 447 Rotax on a
Minimax. The Rotax flat humiliates the VW. Wouldn't have a half VW. Take
off distance with 447 100 feet on 80 degree day. Take off with VW same day
600 feet. Kirk

Well I'll post here when I am getting ready to do
that. And if you wanna do it we can coordinate the
departure out of Florida. I enjoy'd the Bahamas a lot
when I was there a year ago. It would be in my
estimation a superb time. TNK is working on plug n'
play amphibian floats. If they (Ray) are successful,
and are reasonably priced that may be an even greater
fun,, if that's possible.

Bob
I wish you wouldn't do that. I have been there with a direct drive VW and
its a real disappointment. The props that get the most thrust are long ones
that turn slow. My reduction drive VW engine turns its 72 inch prop at 1988
RPM at cruise. For a good climb I turn 3600 turning the prop 2236RPMs. To
turn these engine RPMs direct drive with everything being equal you would
need a 3500cc engine. OK you could compromise the prop efficiency and turn
slightly more RPMs but you would still need a really large VW engine to get
the same performance. At what point is a engine that was designed for 1200cc
too large to be reliable. Some say my 2180cc engine turning 3200RPM is too
much.
Another issue is how much power can you make with a VW engine and keep it
cool. My direct drive VW had to work so hard that my oil temps were near the
upper limit with a large oil cooler and a rich fuel mixture. With the same
engine and the reduction drive I can't seem to keep it warm. I run a lean
fuel mixture and have removed the scoops from the oil cooler and I'm also
cruising 10 MPH faster.
There is a guy at New Kolb (the red head) that is building a direct drive VW
for a MKIII with one of the super long stroke cranks that uses the Chevy rod
journal with a 90mm stroke and 94mm pistons for 2500cc. I tried to talk to
the guy but he just wouldn't listen. The VW is a great engine I'm concerned
that this attempt will sour the people at Kolb on VWs.
I have watched a lot of VW and 1/2 VW powered airplanes fly over the years
and every one of them with direct drive has struggled to get airborne. Watch
me or Jene Smith (maybe even Larry Bourne some year) take off with our
reduction drive VWs and you will understand.
Sorry for the ranting.

the belts. I suspect the engine and reduction drive came off a Quicksilver

--> Kolb-List message posted by: Matt Dralle <dralle@matronics.com>
Hi Kolbers,
Okay, I spent some time yesterday and today looking at options for adding a
nice Chat system to the Matronics systems. I found a nifty web-based
solution that doesn't require any special software other than a late-model
web browser.
It seems to work well and I've set it up for testing on a few of the
Matronics Lists. You'll see a button labeled "Rooms" where I have added
five of the current Lists. If people like the system, I'll add the rest of
the Lists, buy the chat-engine software (currently using an eval copy),
pretty up the wrapper web page, and add a link to the Message trailer.
The chat-client user interface is pretty self explanatory. There's a
little button on the applet that looks like four arrows pointing at the
four corners of the button. Pressing this will decouple the chat window
from the web page container and allow you to resize the chat window to any
size you want.
Give it a try and let me know what you think! I'll be on and off it today
depending on when I'm around. My handle is "MattDralle".
To get started, click on the Link below and enter in your handle. Please
use your *real name* or email address so other members will know who you are.

A few basic questions from someone who didnt build their plane but who
should know this stuff anyway:
what is the D-cell?
Also, I have heard John H. discuss horizontal bracing in the wing a few
times, but I still cant figure exactly what he is talking about. Im
probably thinking about this all wrong, but seems like the only horizontal
bracing is the main spar, leading and trailing edges, and the drag strut,
and I dont think these are what he means. John or somebody, please set me
straight - preferably referring me to Don's wing construction pictures or
other similar photos for clarity.

Erich, if you were to wrap the leading edge with sheet metal from the top
of the spar around to the bottom you would have a complete D cell.
Mine has a half D on one wing (top only) and about 7/8 on the other.
_didn't like the way the right wing was done, by someone else, and did
the left a little different. -flies ok in spite of it. -BB do not archive

In the interest of keeping this list as good as it has been, let's try
to follow Mattes guidelines and delete all but the portion of the
previous message(s) that we are responding to.
Yesterday, a message was posted that contained 100% of the 7 previous

ill take a stab at it Eric
the D-section..or D-cell..is the area in front of the spar...picture a cross
section...and with the spar in the middle...the "D" formed by the front half
When John talks about "horizontal bracing" He is referring to structure to
keep the ribs "in column"....this bracing could be from rib to rib in the
form of X bracing( like the bracing between floor joists in the basement).
It could be flat rib lace cord from rib to rib...or even just extra 5/16th
tubes that jion the ribs laterally along the span.
IN a Kolb wing, the main thing that keeps the rib in column id the fabric
riveted to the ribs in areas that are away from the spar and
leading/trailing edge tubes. If a rib gets loose from the fabric, it could
easily twist sideways and get "out of column"..and therfore collapse or
fail.
AS long as they are straight up an down(In column) they are very strong.
Other areas of "horizontal bracing" (not referring to ribs) might be
considered the drag strut..the spar (which is fine) and the leading and
trailing edge tubes as you describe.
On the FireFly wing..the drag strut is connected only on the ends...one end
on the inner steel rib, and the other on the spar. On heavier Kolb
wings..the drag strut is re-inforced with a brace mid span from the main
spar to the strut, and the brace in made of steel I believe.
...I think.....

> Don't be sorry for anything, as far as I'm concerned you are right on!! The
key here may be the phrase "direct drive" My experience is with a Direct drive
1/2 VW in an N3 pup that was a great flying plane but was really way
underpowered by comparison to the 447 in my Firestar. But I flew it 100 miles for
a
friend of mine ..near Warren, ohio and it flew just wonderfully ....but i was
sitting on the edge all the way any time i got close to landing or taking off
because of the slow speed of the prop...tach said 3450 (maxed out) and it was a
direct drive.
I weighed about 200 at the time, and when I took off from the runway half
way up the mountain at Cadiz, Ohio...I thought for sure on this 2nd leg of each
25 mile leg, that I had bought the big one as the wheels would not leave the
runway as I ran out of runway at the edge of the mountain!!! The ASI said I was
going 37 and that should have been enough to be airborne (as I found on my
first leg), but I wasn't flying. As I came off the cement at the edge of the
runway, I prepared for the nosedown and looked for a clearing to crash land on
the mountainside. Much to my amazement, the plane just kept on going straight
off the end of the runway and I flew the next 25 miles gradually (just barely)
gaining altitude to land at Carrollton Airport. I found an old fart there who
informed me that my dilemma was caused by an incline of the runway at Cadiz.
Not long after that I had a heart attack and died.
Naw, just teasin...but that was one of the scariest flying experiences that I
have had (although flying in the dark with no lights ranks right up there),
and it was enabled by marginal power provided by the 1/2 direct drive VW.
Experiments with prop pitch on this baby proved that power transfer to the air
was
just about optimized. My buddy did get a slightly better prop on there and he
weighed 40 lbs less than me but he still piled it in. Total loss, but no harm
to the pilot...what a mess.... and blessing, at the same time.
This beautiful plane was ultimately deep sixed by my friend,the owner,
because of the same thing, not enough power....couldn't make it over the power
lines
following another MkIII and a Quick which got out handily. He was not hurt at
all because of the similar construction of the N3 to the Kolb...chrome moly
steel tubing ...welded.

They struts. :-)
Seriously Paul, they brace the lift strut to keep it in
column during negative Gs while flying, and especially on
the ground during landing and taxiing over rough fields.

Don/All:
The failure on my Firestar wing starter between the 2d and
3d main rib, counting the outboard rib as 1st. Both wings
failures began at the center false rib rivet hole. When the
leading edge started to fail upward, it pulled the noses of
the ribs, attached to the leading edge tube out of column
laterally. When it was all over, the leading edges of both
wings had failed upward and back to the main spar. I had a
spoiler about 18 inches wide and the length of the wing area
of the main ribs wide.
Failure was caused by failing well out of the design
envelope for many hours, 755 IIRC, dinging a wing
occasionally in little mishaps, and insufficient lateral
bracing of the leading edge tubes.
If this airplane had been flown the way it was intended to
be flown, it would probably still be flying. I take full
responsibility for the wing failures.
It was a very abrupt learning curve. Haven't pulled the
wing off a Kolb in the last 13 years. Of course my flying
style has changed somewhat since March 1990.
Take care,
john h

Kolbers,
I SOLOED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Wow nothing like I expected. Had
to hold short for a King Air on approach then taxied out onto 13 and let her
have it! just as I started my takeoff roll I realized my window was open!
Yikes!!! Got it closed and made a good take off and circled to make the three
requierd touch and goes. First landing was far short of pretty. I bounced then
balloned, got all crossways bounced again then working the rudder like a tail
dragger managed to regain control and settle on to the runway. The next two were
perfect greased landings. Upon returning to the ramp my CFI asked "What tha
heck was that" I said " I don't have a clue but I wont do that again!" Any
way I'm all set to go practice. I will post some photo's of this great day.

On the M3X there are two braces chrome molly for the

Hey, there is a guy who has a neat Mark III in Orlando, Florida, with a
Lotus 2000 monofloat and his own design retractable gear who has flown it to
the Bahamas at least once and maybe more. I'll try to find out his name and
get hold of him. He doesn't have e-mail. I've seen his plane. It has a
912, and a clever arrangement for the fuel tanks. He uses 3 of the regular
5-gallon tanks but they're arranged side-by-side and the cage is modified to
allow him to slide them out so he can carry them to a source to refill them.
I'm on it.

"Mister" John Hauck, Don G, Rick W/All
My son Jim hooked me up with the Kolb-List. I have been found the listings
to be very informative. It was a pleasure to meet you 3 and other Kolbers at
Oshkosh. John - (Jim used the term "mister" as a sign of respect and I
concur), your stories of your experiences are VERY interesting, thorough,
and well written. I enjoy reading the diaries and pictures of your trips and
the planning of your Alaska trip almost as if I were there. Re: The
"Spin-Stall" reply by Jack Hart...the point of differing opinions is well
taken, however, I think your intention may have been mis-understood. It
appears to me that you share your opinions, experiences and information to
be taken at face value for the benefit of the readers not as preachy dogma.
There's no need for each person to reinvent the wheel. VG's sound like a
good idea, but the ANALysis was getting a little ANAL.
For "Honda" Don, I enjoy your hillbilly vernacular. How about "Hondabond"
for dentures? "VW" Rick, Are you going to try that WWII Verner engine?
Matt Draille - Nicely managed site, but if you make it better it'll be
different and for us old-guys change is bad, even if it is change for the
better. I'm waiting for the VG testers to try out the new posting system
and explain it to me. Kolbers, keep the info flowing. John Clayton -

> Beauford
Beauford/All:
I have spun all three of my Kolbs:
Ultrastar
Original Firestar
MKIII
All three spin and recover instantaneously.
The Ultrastar spins like a Cessna 152 without all the
altitude loss.
The Firestar would spin 1/2 turn with stick back to the
stop, full right or left rudder, engine idling, and return
to flying with controls locked in that position. An engine
off spin and the FS spins up like a top with instant
recovery by relaxing the controls.
I'm sorry I can not remember altitude loss for any of the
three models for number of spins. I'll have to do some
spins in Miss P'fer to refresh my memory, but altitude loss
with her or the other two Kolbs was not much. However, would
not want to do one near the ground.
No bad habits with either of the three.
Never got into or near an inadvertent spin with any of them.
Ailerons are still in control during stalls/mushes on all three.
Instant recovery by relaxing controls on all three.
The Firestar would recover from any unusual attitude by
relaxing controls. That includes inverted, tailslides,
falling out of unsuccessful aileron rolls, screwed up hammer
heads, stalling out of loops and wing overs.
No vortex generators on any of them.
I may get around to experimenting with gap seals on rudder
and elevator, but don't have time right now to mess with that.
With well over 3,500 hours and 19+ years flying Kolbs, I
have never found any of them to have bad habits of any kind.
If they did, I probably wouldn't be flying them today.
They will stall level, near the ground, giving the pilot the
impression he is flying, but in a full stall. Nearly
impossible to push the nose over to regain flight before
impact in this configuration. Got into this situation once
with the MKIII and gravity won. Thank God I was strapped in
to a crashworthy airplane or I may have suffered more than
black and blue bruises on bottom of my thighs and loss of my
glasses on impact.
I don't think I will get involved in the experimentation
process of vortex generators. I am pleased with the
performance band of my MKIII. The airplane responds to my
commands and makes me happy the way it is configured.
From a lot of the posts I read concerning vortex generator
experimentation, the test pilots don't have enough time in
Kolbs to know how to fly them in the standard configuration,
much less experiment and change a well proven design that
has been flying for many years.
Take care,
john h
PS: Don't spin without a parachute. And don't be attempt
to be an aerobatic pilot in an airplane that is not designed
for aerobatics. Might kill ya!!!

As Rick said, and has been said before - the VW needs a re-drive to get its
RPM's up, and a prop to match. It also depends a lot on WHich 1/2 VW. 1/2
of a stock 1600 is going to be pretty anemic whatever you do. 1/2 of a
2110cc or 2180cc is going to have a lot more go-gittum - probably on the
order of 50 - 60 horses. I'm not certain, but have heard that the 1/2 VW's
have quite a bit of vibration. Any one know about that ??

circled to make the three requierd touch and goes. First landing was far
short of pretty. I bounced then balloned, got all crossways bounced again
then working the rudder like a tail dragger managed to regain control and
settle on to the runway. The next two were perfect greased landings. Upon
returning to the ramp my CFI asked "What tha heck was that" I said " I

Lar,
I have a buddy who is an extraordinary mechanic & machinist. We have a
mutual friend who had a 1/2 VW in an N3-Pup which vibrated badly. My buddy
rebalanced the crank with a bunch of heavy metal & it ran like silk. It too
took all day to get up to alttitude, but it sure flew nice once there.
Anyway, the factory boys got wind of it & asked my buddy to do a "test"
crank for them. He did. A few months later I read in UL Flying that they
fixed the vibration problem common to the 1/2 VW's & took all the credit.

Hi Craig,
Great! The shape of the pod looks perfect. I've not yet started the wings, so
I'm in no hurry. When you have time let me know and I'll send a check, ok?
I like the way the carbon fiber looks, with the clear on it. Will the UV damage
it if I don't paint it? Would you suggest carbon fiber, or glass?
Take care, Jim

Jim; yes I would love to share the pod with you I have the mould. just tell me
how you would like to have it ( s glass or carbon fiber) I don't think I will
sell the glare shield because it was time consuming and I didn't stitch the leather.
the carbon piece will probably cost about $200

Craig,
That instrument pod, and glare shield is amazing! I
imagined the exact instruments, and needing a larger
pod, however I don't have the skills with fiberglass
or carbon fiber. Would you be willing to build more
of them, and if so, what do you supose it might cost?
I really like the paint job on the panel.

I didn't realize jury struts were standard in the

My MKIIIc has jury struts with clevis pins. There is
one clevis pin on the
wing attach end. The other end is permanently attached
to the main strut but
folds flat with the main strut when disconnected for
wing fold. My MKIIIc
was one of the last few that had stock jury struts
before they changed to
full length tube supports in the main struts that
eliminated the need for
the jury struts. The jury struts add drag and only
help with negative G
limits. Ok and also when a wheel breaks off.
