 Posted: Wed Mar 16, 2016 9:33 am Post subject: FireStar 2 Kit Received ! |
 |
|
Well, the used FS2 kit that I had purchased has arrived! I picked it up form the Yellow Freight terminal (YRC nowdays) last night. Got it back to my hangar, and was able to spend a couple of hours unpacking most of it. I have not been able to do a full inventory, because I do not have a full inventory sheet from Kolb. But I have a lot of various airplane hardware floating around in my hangar 
One of the chimpanzees involved somewhere in the shipping crushed two or three small tubes in the horizontal stabilizers.
The fuselage cage had been hand-painted with white brush-on house paint or something. I'm thankful for that, because there is only minor corrosion in the form of brown stains in the white paint, and no serious pitting. I will eventually have it blasted and re-primed or powder coated. Any suggestions, warnings, or experience good or bad with powder coating and steel priming is welcome.
The kit came with brownish-red plastic wheels and 15 x 6.00 x 6 tires. Alumuinum gear legs, short windshield, one gas can. It is serial number FS-636, the instruction manual is dated 1996.
The aluminum tube for the tailboom ("fuselage tube" in Kolb language) had apparently been accidentally drilled for the wing ribs, because the original builder did not realize the tubes were different. So I may be able to salvage it, repair it, or plug the holes with "Dead" rivets. Or, I may have to replace the tube.
I will be using 4 stroke power on this, as I have mentioned previously. Dagwodzz has been very kind to spend some quality time with me on the phone educating me about V-twins. Thank you Dagz! I am also looking at the absolutely beautiful Pegasus Power O-100 engine from Pete Plumb in California. I have seen this engine run in person and was very very impressed.
If anyone can point me to specific articles or archives on this list regarding technical errors in the plans or instructions, or common problems building the FireStar, Again I am happy to hear about it.
I have several minor and medium size modifications and tweaks that I am looking into on this airplane. Some of them are aerodynamic (raked tips, VG's, etc.), some of them are engine related (4 stroke), and some of them are mechanical (aircraft quality hardware and fasteners wherever possible... I have this stuff laying around).
Glad to be a brand new, green, wet-behind-the-ears Kolber !

Lots of Youtube videos about using urethane foam
to fill tires, too, but it doesn't remain flexible so
it'll crush up over time and make a mess in something
like an aircraft tire.

These are foam inserts that allow you to run lower pressure
and even run safely when punctured flat.
I'll bet that these foam blocks weigh less than the
three piece tire iron set that was mentioned earlier, or the
can of flat tire repair goop

Yes, I want to make it clear that I'm not trying to
hassle or trash-talk anyone or their product. I do prefer
not having to wrestle with someone just to get an answer
to
my question, but regardless of the effort it takes to get
that answer my motives and agendas are positive and not
negative.
My situation is that I want to fly extreme-STOL up in the
mountains and desert. I've been scouting several
locations in my 172, and believe it or not most of them
are
actually within 50 or 60 miles of the "big
city"
limits. So it's not like I'm going out Grizzly
bear
bow hunting in the Aleutian Islands or anything... but
it's still way too far for me to just "walk into
town" with a tire and wheel in my hands.

I have three metal
tire irons that I carry with me. Less than 1 lb. for
the
set
and with a little water as lubricant they get the tire
off
a
one piece wheel just fine. It's breaking the bead
that's the trick and for that I just use a hammer
with
one iron to get it started. It's not what I'd
use
at

The tires and wheels do look nice, and are likely a
good
option if flying close to home.
However, it seems like you're missing his point.
He's talking about real 'bush' flying, away
from
airports & service facilities. With conventional 2
piece
wheels, you could break them down with simple hand
tools
to
repair a flat, and a small hand pump to re-inflate. But
with
auto-style one piece wheels, it requires specialized
(heavy)
tools to break a tire down for repair. Not likely to be
in
a
tool kit you can carry in a Kolb or other very light

Consider that new engine very carefully. I'm speaking from experience. I was the first to put a VW on a Kolb. It is a big undertaking. First the Pegasus Power O-100 engine uses a difocal mount and kolbs have a bed type mount. I had to fabricate a custom mount for the VW. I had help as GP Aircraft made a prop end mount that made it easier. You will have to fabricate a custom exhaust system. You will need to enter the black science of prop selection. You may like magnetos but I don't, they are heavy, expensive, under powered, and there is a reason they come in pairs. Now the real tough stuff, the engine is still in development. You will be the test pilot for not just the engine installation but for the engine too.
Don't get me wrong I'm not trying to talk you out of it but do not underestimate the task you will be taking on. I spent one extra year installing my VW. Then I changed to a redrive VW engine. Then I had a redrive failure. Then I fabricated a new lower engine mount. Five years later I was still tweaking exhaust systems, Props, carb settings, and redrive ratios. Eighteen years later I'm still battling engine noise - the engine mount transmits too much vibration noise to the airframe. One of my high engine mounts had a soft enough mount that was very smooth and quiet but chewed up engine mounting bushings/dampers.
One more thing, engine builders overestimate power and underestimate weight and price.
It could be a worthy challenge but are you up to it?

He's talking about real 'bush' flying, away

Very valid points from a man who has been there and done that, and seems to still be doing it.
After considering where I fly and how unforgiving gravity is, I go with the best, proven, engine I can find for my aircraft.

Bill
Consider that new engine very carefully. I'm speaking from experience. I was the first to put a VW on a Kolb. It is a big undertaking. First the Pegasus Power O-100 engine uses a difocal mount and kolbs have a bed type mount. I had to fabricate a custom mount for the VW. I had help as GP Aircraft made a prop end mount that made it easier. You will have to fabricate a custom exhaust system. You will need to enter the black science of prop selection. You may like magnetos but I don't, they are heavy, expensive, under powered, and there is a reason they come in pairs. Now the real tough stuff, the engine is still in development. You will be the test pilot for not just the engine installation but for the engine too.
Don't get me wrong I'm not trying to talk you out of it but do not underestimate the task you will be taking on. I spent one extra year installing my VW. Then I changed to a redrive VW engine. Then I had a redrive failure. Then I fabricated a new lower engine mount. Five years later I was still tweaking exhaust systems, Props, carb settings, and redrive ratios. Eighteen years later I'm still battling engine noise - the engine mount transmits too much vibration noise to the airframe. One of my high engine mounts had a soft enough mount that was very smooth and quiet but chewed up engine mounting bushings/dampers.
One more thing, engine builders overestimate power and underestimate weight and price.
It could be a worthy challenge but are you up to it?

Well, the used FS2 kit that I had purchased has arrived! I picked it up form the Yellow Freight terminal (YRC nowdays) last night. Got it back to my hangar, and was able to spend a couple of hours unpacking most of it. I have not been able to do a full inventory, because I do not have a full inventory sheet from Kolb. But I have a lot of various airplane hardware floating around in my hangar
One of the chimpanzees involved somewhere in the shipping crushed two or three small tubes in the horizontal stabilizers.
The fuselage cage had been hand-painted with white brush-on house paint or something. I'm thankful for that, because there is only minor corrosion in the form of brown stains in the white paint, and no serious pitting. I will eventually have it blasted and re-primed or powder coated. Any suggestions, warnings, or experience good or bad with powder coating and steel priming is welcome.
The kit came with brownish-red plastic wheels and 15 x 6.00 x 6 tires. Alumuinum gear legs, short windshield, one gas can. It is serial number FS-636, the instruction manual is dated 1996.
The aluminum tube for the tailboom ("fuselage tube" in Kolb language) had apparently been accidentally drilled for the wing ribs, because the original builder did not realize the tubes were different. So I may be able to salvage it, repair it, or plug the holes with "Dead" rivets. Or, I may have to replace the tube.
I will be using 4 stroke power on this, as I have mentioned previously. Dagwodzz has been very kind to spend some quality time with me on the phone educating me about V-twins. Thank you Dagz! I am also looking at the absolutely beautiful Pegasus Power O-100 engine from Pete Plumb in California. I have seen this engine run in person and was very very impressed.
If anyone can point me to specific articles or archives on this list regarding technical errors in the plans or instructions, or common problems building the FireStar, Again I am happy to hear about it.
I have several minor and medium size modifications and tweaks that I am looking into on this airplane. Some of them are aerodynamic (raked tips, VG's, etc.), some of them are engine related (4 stroke), and some of them are mechanical (aircraft quality hardware and fasteners wherever possible... I have this stuff laying around).
Glad to be a brand new, green, wet-behind-the-ears Kolber !

it'll crush up over time and make a mess in something

Homer Kolb designed his wing for a reason. It works.
I have never, in 32 years changed the outside dimensions of an Ultrastar, Firestar, or MKIII wing. They work for me.
Plastic wheels don't even make good paper weights.
A varmint decided to taste the fabric on the right main gear of my MKIII. We just completely rebuilt, fabric and paint, both main gear a year ago. I'd shoot him is I could find him. Have no idea what it was. I was over at Gantt International Airport yesterday taking photos of the damage. Took a couple extra of the environment over there. My little piece of heaven.
Spring has sprung at hauck's holler. The weeds have sprouted. One can watch them grow they are so fast. Spring is my favorite season. Everything is already covered with pollen.

Thanks Rick,
I'm not taking it lightly. I have started to look at just what it would take to adapt the O-100 engine, and yes it is completely different than the Rotax bed mount built into the airframe.
I happen to be very fortunate in that I have a good infrastructure of structural engineering, welding, machinists, and fabricators available to me. I could never take this on without having built up that infrastructure.
I just know that I'm more comfortable with 4 stroke power, and I want the reliability/noise benefits of those engines.

a couple of hours unpacking most of it. I have not been able
to do a full inventory, because I do not have a full
inventory sheet from Kolb. But I have a lot of various
airplane hardware floating around in my hangar
One of the chimpanzees involved somewhere in the shipping
crushed two or three small tubes in the horizontal
stabilizers.
The fuselage cage had been hand-painted with white brush-on
house paint or something. I'm thankful for that, because
there is only minor corrosion in the form of brown stains in
the white paint, and no serious pitting. I will eventually
have it blasted and re-primed or powder coated. Any
suggestions, warnings, or experience good or bad with powder
coating and steel priming is welcome.
The kit came with brownish-red plastic wheels and 15 x 6.00
x 6 tires. Alumuinum gear legs, short windshield, one gas
can. It is serial number FS-636, the instruction manual is
dated 1996.
The aluminum tube for the tailboom ("fuselage
tube" in Kolb language) had apparently been
accidentally drilled for the wing ribs, because the original
builder did not realize the tubes were different. So I may
be able to salvage it, repair it, or plug the holes with
"Dead" rivets. Or, I may have to replace the
tube.
I will be using 4 stroke power on this, as I have mentioned
previously. Dagwodzz has been very kind to spend some
quality time with me on the phone educating me about
V-twins. Thank you Dagz! I am also looking at the absolutely
beautiful Pegasus Power O-100 engine from Pete Plumb in
California. I have seen this engine run in person and was
very very impressed.
If anyone can point me to specific articles or archives on
this list regarding technical errors in the plans or
instructions, or common problems building the FireStar,
Again I am happy to hear about it.
I have several minor and medium size modifications and
tweaks that I am looking into on this airplane. Some of them
are aerodynamic (raked tips, VG's, etc.), some of them
are engine related (4 stroke), and some of them are
mechanical (aircraft quality hardware and fasteners wherever
possible... I have this stuff laying around).
Glad to be a brand new, green, wet-behind-the-ears Kolber !

"Homer Kolb designed his wing for a reason. It works.

me."
I agree completely, I'm sure the stock Kolb wing works perfectly well. But on an experimental homebuilt I'm looking to add some of the small amount of knowledge and experience that I've gained through about the same 30+ years in aviation.
Mr. Kolb himself changed the wing dimensions to create the Slingshot, Kolbra, Firelfy, and others. He also changed the angle of incidence (wing mounting angle) to create different characteristics on different models.
Raked wingtips are shown to work, especially at high AoA and low speeds. They create a pressure field that slightly reduces the wingtip vortex.
VG's are shown to work great, especially on simple turbulent flow airfoils like the Cub, Kolb, and Aeronca. They help the airflow stay attached to the wing at higher AoA. This results in better control authority at low speeds, which will be a lifesaver in off-airport STOL operations.
On a high drag airplane like a Kolb, reducing drag doesn't make you go any faster. It allows you to fly at the same speed with less power or fuel burn.
Mr. Kolb designed the landing gear to be as easy and low-risk for new or low-time pilots as possible. It worked, and the Kolb has a wonderful reputation for easy ground handling. This is just what the doctor ordered for a kit plane that was safe for low time pilots. But this mellow ground handling comes at the cost of losing the ideal ground angle for the wing to take off and land slower. A longer or taller landing gear requires a slightly more experienced pilot, but you get better STOL performance in the bargain.

Bill B/Kolbers:
With your background you should realize what it takes to "make" an airplane engine, and make it work safely and reliably, while making more power than ever required.
Takes but a minute to discover Rotax 2 and 4 stroke engines, a couple VW's, and a smattering of HKS's are what is pushing Kolbs though the air. Since this thing started about 40 years ago, there have been a lot of different power plants tried, but it comes down to the few I mentioned that are still around and still flying.
I had a buddy, back in the 80's, that had a J3 Kitten powered with a half VW, a 4 stroke. At the time I was flying my FS with a 447. He was always bragging about how much more reliable his 4 stroke was than my 2 stroke. Of course, he had never had an engine stoppage or failure, and I had had plenty of both. One day we were flying a cross country from Bessemer to Wetumpka, AL. We were chatting on the radio when my buddy said, "Uh oh!", as the Kitten rapidly descended into a farmer's field. His 4 stroke had broken a valve spring.
All these engines, 2 and 4 stroke will quit when they get ready, for one reason or the other. When I fly places that I cannot survive if I have an engine out, I say a little prayer to my Higher Power, and accept that fact if the engine stops. At my age I am getting less inclined to take those chances, but it is difficult to fly anywhere when you, at some time during that flight, don't find yourself in that situation.
Some folks thrive on developing and experimenting with our airplanes. That is what keeps them going. We have all done our share over the years. So get out there and get a new engine going that is safe, reliable, more power than ever needed, cheap, and burns 1 GPH.
Time to roll out the MKIII and get the pollen and barn dust washed off her.

I assume that Rick is talking about the Pegasus. I'd bet it uses the standard Cont. conical mount, but it's still on the back of the engine instead of the bottom. But more important (at least to me), be sure to truly count the cost. In the early versions I saw, the actual cost to get one running was 2 or 3 times the kit cost. Note that there are no cylinders mentioned on the list of what's included. Assuming that you must buy your own cylinders, ask him how he can safely run 9-1 compression with the stock Cont. cyl heads & mogas. (Original engine had 7.0-1 compression.) Also, ask what the *real* horsepower is. Most Cont guys say that the original O-200 4 cyl was only good for maybe 85-90 hp on its best day, and with a fixed pitch prop, you won't come anywhere near rated power on takeoff, when you need it. Half of 90 is only 45 HP. On a tractor a/c, a big Vtwin with reduction swinging a large diameter prop just might outclimb the O-100, even carrying an extra 15-20 lbs of weight.
There are other (a lot more work required) options, like

Consider that new engine very carefully. I'm speaking from experience. I was the first to put a VW on a Kolb. It is a big undertaking. First the Pegasus Power O-100 engine uses a difocal mount and kolbs have a bed type mount. I had to fabricate a custom mount for the VW. I had help as GP Aircraft made a prop end mount that made it easier. You will have to fabricate a custom exhaust system. You will need to enter the black science of prop selection. You may like magnetos but I don't, they are heavy, expensive, under powered, and there is a reason they come in pairs. Now the real tough stuff, the engine is still in development. You will be the test pilot for not just the engine installation but for the engine too.
Don't get me wrong I'm not trying to talk you out of it but do not underestimate the task you will be taking on. I spent one extra year installing my VW. Then I changed to a redrive VW engine. Then I had a redrive failure. Then I fabricated a new lower engine mount. Five years later I was still tweaking exhaust systems, Props, carb settings, and redrive ratios. Eighteen years later I'm still battling engine noise - the engine mount transmits too much vibration noise to the airframe. One of my high engine mounts had a soft enough mount that was very smooth and quiet but chewed up engine mounting bushings/dampers.
One more thing, engine builders overestimate power and underestimate weight and price.
It could be a worthy challenge but are you up to it?

The kit came with brownish-red plastic wheels and 15 x 6.00 x 6 tires. Alumuinum gear legs, short windshield, one gas can. It is serial number FS-636, the instruction manual is dated 1996.
The aluminum tube for the tailboom ("fuselage tube" in Kolb language) had apparently been accidentally drilled for the wing ribs, because the original builder did not realize the tubes were different. So I may be able to salvage it, repair it, or plug the holes with "Dead" rivets. Or, I may have to replace the tube.
I will be using 4 stroke power on this, as I have mentioned previously. Dagwodzz has been very kind to spend some quality time with me on the phone educating me about V-twins. Thank you Dagz!

Aw shucks. Not all that greedy.., Even if it burnt 2 GPH!!!! I'm all in... He said with a big grin on his face;-)
Boyd. Lol
Xxxxxxxxxxxxx
that is safe, reliable, more power than ever needed, cheap, and burns 1 GPH.

The prototype Pegasus does use the stock Continental conical mounts on the back of the case. There may be another upcoming mounting system for it that might be better suited to the Kolb, but that is for Pete to discuss and not me.
The O-200 makes horsepower in proportion to the RPM, I have flown the O-200 from 2000 RPM to 4300 RPM (Reno F-1 race). The power curve drops off dramatically above 3200, and reliability goes way down. A properly balanced and lubricated O-200 (or O-100) will maintain very good reliability at 3000 RPM. Better than a stock un-balanced
I am not an engine expert, but I do know that actual real-world reliability over the last 60+ years of airplane engines strongly favors the 4 stroke engines. When Rotax finally decided to create an engine specifically for airplanes, they chose a 4 stroke despite the fact that by then they were the absolute world leader in 2 stroke engines in experimental aircraft. There has to be a reason for that, and it's not just EPA pollution regulations.
I assume that
Rick is talking about the
Pegasus. I'd bet it uses the standard Cont.
conical mount, but
it's still on the back of the engine instead of
the bottom. But
more important (at least to me), be sure to truly
count the cost.
In the early versions I saw, the actual cost to get
one running
was 2 or 3 times the kit cost. Note that there are no
cylinders
mentioned on the list of what's included. Assuming
that you must
buy your own cylinders, ask him how he can safely run
9-1
compression with the stock Cont. cyl heads &
mogas. (Original
engine had 7.0-1 compression.) Also, ask what the
*real*
horsepower is. Most Cont guys say that the original
O-200 4 cyl
was only good for maybe 85-90 hp on its best day, and
with a fixed
pitch prop, you won't come anywhere near rated
power on takeoff,
when you need it. Half of 90 is only 45 HP. On a
tractor a/c, a
big Vtwin with reduction swinging a large diameter
prop just might
outclimb the O-100, even carrying an extra 15-20 lbs
of weight.
There are other (a lot more work required) options,
like

Well, the used FS2 kit that I had purchased has
arrived! I
picked it up form the Yellow Freight terminal
(YRC nowdays)
last night. Got it back to my hangar, and was
able to spend
a couple of hours unpacking most of it. I have
not been able
to do a full inventory, because I do not have a
full
inventory sheet from Kolb. But I have a lot of
various
airplane hardware floating around in my hangar
One of the chimpanzees involved somewhere in the
shipping
crushed two or three small tubes in the
horizontal
stabilizers.
The fuselage cage had been hand-painted with
white brush-on
house paint or something. I'm thankful for
that, because
there is only minor corrosion in the form of
brown stains in
the white paint, and no serious pitting. I will
eventually
have it blasted and re-primed or powder coated.
Any
suggestions, warnings, or experience good or bad
with powder
coating and steel priming is welcome.
The kit came with brownish-red plastic wheels
and 15 x 6.00
x 6 tires. Alumuinum gear legs, short
windshield, one gas
can. It is serial number FS-636, the instruction
manual is
dated 1996.
The aluminum tube for the tailboom
("fuselage tube" in Kolb
language) had apparently been accidentally
drilled for the
wing ribs, because the original builder did not
realize the
tubes were different. So I may be able to
salvage it, repair
it, or plug the holes with "Dead"
rivets. Or, I may have to
replace the tube.
I will be using 4 stroke power on this, as I
have mentioned
previously. Dagwodzz has been very kind to spend
some
quality time with me on the phone educating me
about
V-twins. Thank you Dagz! I am also looking at
the absolutely
beautiful Pegasus Power O-100 engine from Pete
Plumb in
California. I have seen this engine run in
person and was
very very impressed.
If anyone can point me to specific articles or
archives on
this list regarding technical errors in the
plans or
instructions, or common problems building the
FireStar,
Again I am happy to hear about it.
I have several minor and medium size
modifications and
tweaks that I am looking into on this airplane.
Some of them
are aerodynamic (raked tips, VG's, etc.),
some of them are
engine related (4 stroke), and some of them are
mechanical
(aircraft quality hardware and fasteners
wherever
possible... I have this stuff laying around).
Glad to be a brand new, green,

These are foam inserts that allow you to run

No argument from me on the 4 stroke issue; both links are to 4 stroke
engines. If you try to run the Pegasus direct drive at >3k rpm, you're
going to hit the same wall that Rick did with his VW; inadequate mass
flow through the required small diameter prop at the relatively low
speeds of a Kolb. If you run it at Continental-like rpms with an
adequate diameter prop, I'd bet you'll do good to get 40 hp.

Hi Folks:
The paragraphs in quotation marks are Bill B's.
Homer Kolb didn't design the Kolbra. That aircraft was designed and built some time after the original Kolb Aircraft Co was sold.
"Mr. Kolb himself changed the wing dimensions to create the Slingshot, Kolbra, Firelfy, and others. He also changed the angle of incidence (wing mounting angle) to create different characteristics on different models."
All Kolb wing dimensions are the same, except length of the wing panel. Shape of the rib and cord is the same on all models.
The Slingshot had less incidence because of the high main gear and the nose high attitude the aircraft sat on the ground. It also flew faster, pulling the tail boom parallel through the air stream. At slower speeds the SS really drags its tail. Very tail low. Other Kolb models fly tail high because of the excessive incidence.
"Raked wingtips are shown to work, especially at high AoA and low speeds. They create a pressure field that slightly reduces the wingtip vortex."
I think you will find that Homer's wingtip takes care of the above.
"VG's are shown to work great, especially on simple turbulent flow airfoils like the Cub, Kolb, and Aeronca. They help the airflow stay attached to the wing at higher AoA. This results in better control authority at low speeds, which will be a lifesaver in off-airport STOL operations."
All Kolb models have excellent low speed flight characteristics without VGs. About the only thing I have been able to determine with the addition of VGs on a Kolb is more gentle break on landing, and slightly less stall speed.
"Mr. Kolb designed the landing gear to be as easy and low-risk for new or low-time pilots as possible. It worked, and the Kolb has a wonderful reputation for easy ground handling. This is just what the doctor ordered for a kit plane that was safe for low time pilots. But this mellow ground handling comes at the cost of losing the ideal ground angle for the wing to take off and land slower. A longer or taller landing gear requires a slightly more experienced pilot, but you get better STOL performance in the bargain."
The Hauck Brothers have been designing and building "tall" landing gear for Kolb aircraft for 30 years. We put the first pair of heat treated 4130 legs on a Kolb. The main reason we started experimenting with long legs on my FS was the lack of brakes. One of the first mods to my FS was 4130 streamlined lift struts. They cleaned up the FS so much I couldn't get it stopped on my short grass strip. The 36" legs turned the bottom of the wing up more and helped slow the FS down on landing. They also made nice springs, and worked wonders for softening up the suspension.
BTW Bill B, tell us about your Kolb experience, please.

I have no Kolb experience whatsoever. This is my first Kolb. So some of my ideas may not work out as well as I hope, and some of them may work better than I imagined. The challenge and enjoyment of improving the performance of an already good airplane is one of the things I'm looking forward to.
I have a specific question which you might be able to answer: If you put the wing on a FireStar at the lower incidence angle of the Slingshot, and then put on the taller gear from the Slingshot, would you get both benefits (a higher cruise speed from the tailboom flying straight), AND better STOL performance (from the higher ground angle)?

I always thought dragging the tail boom straight, instead of sideways through the air, would clean it up a bit and increase cruise. The SS and Kolbra utilize that design technique with lower incidence to increase cruise. John Williamson's Kolbra, with 912ULS, same engine on my MKIII, cruised 10 mph faster at the same rpm. Top speed is about 10 to 15 mph quicker. The major difference in drag between the Kolbra/SS and the MKIII was the difference between the width and shape of the fuselage. Also, the Kolbra had less wing area because it did not have flaps. The MKIII flies slower and gets off the ground quicker.
Actually, the fuselage of the FS would have to be redesigned because the tail boom was designed to fly tail high. Flying with the tail boom horizontal would make the pilot feel as though he were laying on his back and climbing all the time.
My original Firestar was faster and flew slower than the FSII. It had full span ailerons. The FSII is like the Kolbra with half span.
I am a firm believer is extremely tight fabric. I believe this is one of the major differences between air speed/flight characteristic differences of the same model Kolbs. My MKIII has never been outrun by another MKIII. Same for my original FS. Both aircraft had fabric that bowed the tubes on wings and empennage. Soft fabric changes shape much more than tight fabric.
There were a lot of things I would have liked to experiment with my Kolbs over the last 32 years, but age caught up with me before I got them all done. Then I got to the stage that what I have now is great. It does what I need. It is an 85 mph cruise aircraft. If I can find a 15 mph tailwind, then I've got a temporary 100 mph airplane across the ground. It will carry everything I can cram into it to keep me and it going for extended periods of time. So far, the longest duration flight was 48 days. The longest flight was 17,400 sm in 41 days and 232.0 flight hours. It will keep me in the air for 5 hours, if I could do that without wetting my pants. It gets me in and out of tiny fields, two track trails, gravel bars, beaches on the Atlantic, the Gulf of Mexico, the Arctic Ocean, and small dry lakes in the dessert. It does much more than Homer Kolb and John Hauck ever dreamed one of his little airplanes would do. It takes me where I want to go. All I have to do is put gas in it, take off and point the nose in that direction.

Man, let me know if you ever want to sell Miss Pfer. 🔽🔽 that was quite the sales pitch!

I always thought dragging the tail boom straight, instead of sideways through the air, would clean it up a bit and increase cruise. The SS and Kolbra utilize that design technique with lower incidence to increase cruise. John Williamson's Kolbra, with 912ULS, same engine on my MKIII, cruised 10 mph faster at the same rpm. Top speed is about 10 to 15 mph quicker. The major difference in drag between the Kolbra/SS and the MKIII was the difference between the width and shape of the fuselage. Also, the Kolbra had less wing area because it did not have flaps. The MKIII flies slower and gets off the ground quicker.
Actually, the fuselage of the FS would have to be redesigned because the tail boom was designed to fly tail high. Flying with the tail boom horizontal would make the pilot feel as though he were laying on his back and climbing all the time.
My original Firestar was faster and flew slower than the FSII. It had full span ailerons. The FSII is like the Kolbra with half span.
I am a firm believer is extremely tight fabric. I believe this is one of the major differences between air speed/flight characteristic differences of the same model Kolbs. My MKIII has never been outrun by another MKIII. Same for my original FS. Both aircraft had fabric that bowed the tubes on wings and empennage. Soft fabric changes shape much more than tight fabric.
There were a lot of things I would have liked to experiment with my Kolbs over the last 32 years, but age caught up with me before I got them all done. Then I got to the stage that what I have now is great. It does what I need. It is an 85 mph cruise aircraft. If I can find a 15 mph tailwind, then I've got a temporary 100 mph airplane across the ground. It will carry everything I can cram into it to keep me and it going for extended periods of time. So far, the longest duration flight was 48 days. The longest flight was 17,400 sm in 41 days and 232.0 flight hours. It will keep me in the air for 5 hours, if I could do that without wetting my pants. It gets me in and out of tiny fields, two track trails, gravel bars, beaches on the Atlantic, the Gulf of Mexico, the Arctic Ocean, and small dry lakes in the dessert. It does much more than Homer Kolb and John Hauck ever dreamed one of his little airplanes would do. It takes me where I want to go. All I have to do is put gas in it, take off and point the nose in that direction.

Bill, IMOH powder coating is great for patio furniture, office machinery,
and other expendibles, but is not suitable for an airframe. It looks great
straight out of the oven, but once it gets some time on it cracks form
letting moisture in and brown streaks, just like those you are seeing on
your airframe, begin to form. The only solution is to grind it off and
patch it with paint.
I much prefer two part epoxy paint (urethanes, like Aerothane, release
cyanide gas so you must have an air supply to shoot them). You can get it
from O'Reilly's Auto Parts (about $40 a quart)
http://www.oreillyauto.com/site/c/detail/TRS2/6101/N2541.oap?ck=Search_N2541_-1_-1&pt=N2541&ppt=C0171
and the small gun in the Harbor Freight HVLP set (usually about $45) works
great for tubes;

Give it at least four days to fully harden before applying fabric if using
the Poly Fiber system so the solvents won't attack the epoxy. Now you have
something you can repair as necessary.
Anyway, that's what I use and I like it. Also works great on aluminum parts
if you alodine them first.
