Hi Rev. Pike,
I agree. The variety of shapes and configurations for various
mfgr's VG's is amazing. I've flown with at least 3 different makes on GA
aircraft, mainly Cessna 400-series and Piper twins. Some run parallel down
the entire wing, some are on just half the wing, others are paired in 'V'
shapes, and some can be found on the bottom of the horizontal stab. They
even have directions if a few fall off - just fly the aircraft as if there
are no VG's. Some did give a more pronounced stall break, but the over-all
improvements in handling were worth the trade-off.

was wondering if anyone has ever made a good comparison between IVO, 64" and
a Warp prop of the same length. I am curious as I have an IVO and my buddy
has a Warp on his SlingShot. He has better climb, cruise and gas mileage
than I do. I am a heavier plane but he is larger in size. Anyone make a
direct, try one, take it off and try another type comparison on a Kolb that
would compare to the SlingShot? Would be happy to hear. Ted Cowan, Alabama

Hi,
the only way that John is going to be convinced of the efficacy of VG`s is
to fit some to his own bird and try it. Kit built planes vary quite a bit
in performance depending on the builder and flying one against the other
would be a pretty useless exercise.
The only way is to fly a single plane, establish a datum, fit the VG`s and
fly it and measure again.
Cheers
Pat

If not an air leak, check for momentary fuel system constriction problems.
Look for water in the bottom of the float bowl, blow out or replace the fuel
filter, check fuel pressure, your pump may be marginal for the higher flow
rates.

Jack has a point here, if the fuel pump is not keeping up with demand at
full throttle, the float bowel level could be dropping enough to lean the
mixture causing the engine to rev slightly. Between the lean burn being
hotter and lack of lubricating fuel oil mix this could lead to a seizure on
climb out. Not good.
Regardless I'll bet its one of the problems mentioned by Earl, Jack or
myself, please let us know what you find.

Sizes and locations of vortex generators are going to be different for each different
aircraft. VG's will probably be an improvement no matter what, but to
get the OPTIMUM benefit, they need to be of the correct size, shape, and placement
on the wing.
The vortex generators sold by www.landshorter.com seem to be designed for airplanes close to our size and speed range, so im figuring they are going to get the sizes and shapes closer to optimum than I could by cutting my own.

Have they actually designed them for a Kolb and if so are the test

--> Kolb-List message posted by: "David.Lehman" <david@davidlehman.net>
Received this from the SPA this morning... This affects Kolbs on amphibs too...
Seaplane Pilots Association to david
More options 8:19 am (5 minutes ago)
Dear Members:
** Comments due this coming Tuesday, January 24, 2006 **
A petition by Czech Aircraft Works for exemption from current Light Sport rules
opens a new opportunity for members to encourage the FAA to accept amphibious
landing gear on light sport aircraft, but the window for comments is very tight!
The petition seeks certification of the Czech Aircraft Works Mermaid with an exemption
to permit amphibious landing gear. Czech Aircraft Works has been denied
S-LSA certification on grounds that the airplane's amphibious landing gear can
be repositioned in flight. The Seaplane Pilots Association first warned potential
buyers and manufacturers that FAA verbal claims about the acceptability
of amphibious landing gear were not backed by the written Light Sport rules in
2004. The FAA has since acknowledged that the Light Sport rules as written do
not permit amphibious operations, and has repeatedly indicated that the rule's
language was a mistake that would be corrected. To date, no correction has
been made.
Czech Aircraft Work's petition gives the public an opportunity to provide official
comments to the FAA in support of permitting amphibious landing gear on Light
Sport Aircraft. If approved, the petition will also clear the way for further
exemptions and/or accelerate revision of the Light Sport rules.
For more information about this issue, including how to comment, visit SPA's Issue Brief at http://www.seaplanes.org/advocacy/lsamphib.htm.

This topic is always interesting... there are those that have installed VG's and
would never go back and there are those that have never tried them and have
lots of doubt and skepticism.... rightfully so!
When I first read about them on Jack Hart's website several months after I started
flying my Firefly in Jan02, I was a very sceptical that something so seemingly
insignificant could make that much difference in how the Firefly performs,
but Jack's explanation and info was compelling, so I decided to go to HD and
make up a set from Aluminum flashing. I installed them with long strips of electrical
tape through the center between the fins, in the bottom of each valley,
11-12" back from leading edge, as Jack recommended, based on his testing.
I taped them on, so I could easily remove them after proving to myself they didn't
make that much difference.... well I did remove them after a couple flights....
to install them permanently!! I put silicone under each one and then
reinstalled electrical tape as a backup safety factor and I check them reguarly,
but have never had one come loose one bit.
All you guys that are doubters and skeptics, the only thing I have to say to you
is try them on your plane before you give lots of advice or plant doubt in others
minds. I assure you there is nothing you will ever do to your Kolb that
will get close to as much bang for the buck as even home made vortex generators
will do for your Kolb. I have never noticed a single negative characteristic,
regarding the way my plane flies, performance or handling. In fact, just
the opposite. The Firefly had quite a bit of overbanking tendency before....
not now! Stalls are gentler and slow speed flight is incredibly stable... feels
like I can hang from the prop and never drop a wing. Aileron effectivess and
authority is much better, stall speed is lower, etc, etc... Make sure you
also install them on the lower side of the Horizontal Stab's in the rear or your
tail will stall before your wings.
If you don't believe they work, then keep flying without them, but please don't
discourage those newbies that are curious. Some folks are perfectly happy with
their planes characteristics and then there are some of us that always are
interested in improving what is already good. These planes fly great without
Vortex Generators, but they fly even better with them. For me, I want to have
them on when I'm in an engine out situation and need to put it down in a small
space and want to land as slow as possible.
I'm for sure in the category of folks that would never go back to flying my Firefly
without them! Every claim Jack made was right on!! Thanks Jack for making
me aware of them early on in my flying experience!! Your website was a wealth
of info to me early on and I'm sure others have learned from your website
as well. Keep up the good work!!
Cheers, Jim

Michael -
I bought a set of the Landshorter VGs, but have not yet installed them on my
Kolb. For a hundred bucks, it's worth it (to me) for the time I'd save
compared to manufacturing a set from scratch. They are single-fin VGs, made
of clear Lexan
The instructions recommend a spacing interval of 2.5 to 3 inches. However,
I am contemplating the idea of placing one VG in each valley, for a total of
28 per wing for a Mark-III. I wonder if this spacing would still allow the
VGs to be effective?
Has anybody else on the Kolb List installed the Landshorter VGs?
If so, how did you space them?

I installed Lexan type VGs on my experimental Super Cub and wished I had gone with
metal (like on my Firestar)... In the process of cleaning the wings, three
times I broke the Lexan VGs and had to replace them... They're not as flexible
as they look...

--> Kolb-List message posted by: "David Kulp" <undoctor@rcn.com>
Kolb builders,
We've had severe wind the past few days. Newspaper reported one man lost about
18 evergreen trees. I lost one Ultrastar. I had the wings folded and covered
for winter and a blast of wind tore the left side tiedown and the plane (vehicle)
tipped onto its right side, the front five feet of the right wing leading
edge taking the impact on a rise in the ground. The leading edge is visibly
bowed when sighted from the rear - probably almost an inch in about ten feet
- and the skin shows "waves". The trailing edge of the aileron has a bend straight
in between two of the ribs to where the skin is loose. And the tubing that
shapes the skin where the wing stops at the boom tube is bent in a couple
of inches right about at the chord of the wing.
I bought the aircraft already built, so I haven't had the construction experience
many of you have. I'd appreciate a little insight as to what will be involved
in repairing the damage; what I must do and what I can't do. Be gentle -
I just spent a huge amount of time this past fall rebuilding parts of it and repainting
it and I was soooooo looking forward to spring and being in the air
again.
Thanks for your help,
Dave Kulp

I had a similar problem with my 582 in cruise rpm as it would search for a

All,
The Landshorter VG's we have extensively tested and gained approval for on
our Xtra in the UK are spaced at 3" and at 10% of wing chord, this is 225
millimeters back measured from the front apex of the L/E up over the camber.

tough break Dave, looks like you get to learn covering and finishing
now.
The flimsy little parts inside are an easy fix. The time involved to
do it
over is the big deal for someone who was anticipating a flying spring.
Put that wing in the garage and secure the rest of the plane out of the
wind. Do an hour every day and you will be back in shape before you
know it.

Jeremy
Thanks for the photo. I would certainly like to know more. With all that
insulation over the front of the intake system it looks like a turbo system
but the exhaust doesn't look to be connected so????? Also can't see the
engine mount or the redrive system if any.
Looks like the classic flair too high landing. Its painful to see.

That is an old photo. Was around some years back. The aircraft is in
Norway, Sweden, or some where over there. I do not know any more of
the history of this MKIII.

There's a FireStar on floats flying in Florida, and Frank Reynen's Mk III
that's been sold, but they're the only ones to my knowledge. Some years ago
a fella had a Mk III on a Full Lotus monofloat that he used to go bear
watching in British Columbia, Canada, and then over to (I think) the
Kamchatka Peninsula in Russia. There were articles on it, and quite a write
up on the 'net. Maybe someone here still has the URL's for that..........??

Men..
here was my expierience with VG's
Started out by seeing all the posts here a few years ago and wondering about them...did
a patent search on VG designs.
Discovered a wealth of info at the US patent site.
Much info from Military experiments back in the late 40,s up to current mach capable
birds.
INstalled home-made Vgs in the common fashion discussed here and Kolb list members
websites. Used double sided carpet tape and moved them about 3 times fore
and aft..mostly just to see what would happen.
never took em off after that..only moved them around.
Came to the conclusion that the farther forward you put them...the better your
low speed stall and handleing is, the farthwer back...the higher your rate of
climb was..but the stall speed goes back up some. FireFly could be made to climb
at the angle of a Firestar with VG's.
After a year and a half...and after looseing a few...knocking some off when washing..(they
are a pain in this regard)...bought LandShorters for a hundred bucks.
My opinion is they work better than the ones I made..look better, and are easier
to wash around.
They are on the FireFly permanent as far as I am concerned. IN a nutshell...they
give the FFly a wing of a FStar...without the extra drag. If you try em...its
a no-brainer. You will keep em!
BEst 100 bucks I ever spent on this plane.

Putting them in the valleys is probably good, but not at the expense of missing
half of the generators. The instructions say you need X number of generators
for a certain leingth of wing... If you put them in the valleys, and only have
half as many generators as called for, you probably will get aobut half the
benefit from them. Those vorticies need to be over most of the wing, one in
each valley will help, but you are proabably passing up 50% of the benefit doing
it like that. I will put them on as per the instructinos, or maybe inbetween
and on top of each rib if that works out to being very close to what is called
for.
This is just my opinion, I have not tested yet, but I beleive Spacing the vortex
generators to far apart will just limit the amount of wing that they affect,
and limit your benefit from having them...
I would write to the email address on www.landshorter.com They have done all types of testing and im sure they would answer your question far better than I ever could.

I guess it would be almost too obvious to suggest that since there are a
whole herd of Kolb pilots who have done all sorts of VG testing on
Kolbs, and know what works, then maybe it might be useful to listen to
what they are saying and try what they are doing?
Nah, never mind. That's a waste of time.
Ask somebody else.
