Hi Pat. Here in Holland the general perception is that the Canadians
liberated us. Some days later came the Brits but because they were
better looking they got all the girls...
Ironically, the folks that hit our beaches nowadays are the Germans.
They invade us by thousands on a sunny day.
I think it takes a simplification like "The longest day" to explain it
to our kids...
OB Kolb subject: Pat, is it flying yet?
Greetings from Holland.

Polytone whites are REAL stingy with the pigment. Anyone about to
use it should consider that they will either need twice as much or maybe
find a compatible pigment to add from an automotive paint supplier.
-Even with a good poly spray undercoat it will look an anemic white
unless several coats are slathered on. Personally I don't like those
real thicky looking paint jobs.

Fireflyers,
I need help! I am trying to verify if my tach is correct. I have secured
an optical tach. My problem is. How do you tell which gearbox you have and
what the gear ratio is. My Firefly is nearly 30 mi from my house now, so I
cant go out and look at it in the garage like I used to. I purchased the 447
engine package from the New Kolb.. I need to figure out what rpms the prop
should turn to equal 6300 rpms at the engine . Also the manual says to re-torque
the heads to 221 inch pounds at 2 hours run time. My torque wrench only goes
to 200 " lbs. I think that equates to 18-19 foot pounds. Does that sound
right?

Topher and Group,
Now that I have my Firestar down to 3 gph at 60 mph, I'd like to get it
to cruise faster without burning too much more fuel. 80 mph at 4 gph
would be a nice goal. Maybe some day I will change to an HKS700, but
for now, I would like to see how much improvement I can make with a
503.
Currently, I am fully enclosed to behind the back seat. How much
improvement might I get if I enclosed the area above the tanks? What
else might I do to get my Firestar to cruise more efficiently? I do
have streamline struts.
I'm looking for ideas from anyone with similar interest, knowledge or
experience.

John/Everyone
Very nice photos. Thanks for sharing them.
For those of you that were sill out flying after Monument Valley I got a
response from Mary Jones at EAA's Sport Pilot. She promised that she would
publish a report of our Monument Valley flyin if I sent her a write up and
photos. So I asked for everyone's best photos to be placed on George
Alexander's web site at http://home.comcast.net/~kolbflyer/ by sending
George a copy of you best photos at gtalexander@att.net
We didn't get very good response to this request so I went ahead and started
writing The following is a first cut at the article. PLEASE send me your
comments AND recommendations for the best photos to put in the article and
were. Again I'm not a writer so please help. Also I stole some words from
Lar's web site. Also I didn't have the photos from the Johns (times three)
when I wrote this so everyone send me your votes for the best photos and
were (in the article) you would put them.
On May 20-22 we had our third annual Kolb Flyin at Monument Valley. Some
have said unplanned and unorganized but everything was perfect so it's
agreed that we will not fix it.
We used the wonderful facilities at Goulding's Resort. They have a 1st
class facility with a full range of services. At left center is the hotel,
restaurant, gift shop and museum. Center is the gas station, snack
shop/convenience store, and car wash. Laundromat is behind it, and airport
to the right and in front. Community services and campground are in the
green area in the canyon. Prices are fair (cheep by air show standards) ,
service excellent, food delicious. What more could you ask for ?? Be sure
to try the Navajo Taco in the restaurant.
{Larry Bourne's Goulding Photo here}
A Kluster of Kolbs ?? Nawww, too trite, but we did have a good turnout with
Mk III's, FireStars, FireFlies, and a Kolbra, not to mention a Cessna C175
and a Mooney
{Larry Bourne's Flight line Photo here}
More than Half the Kolbs at the Flyin actually flew in. There were two from
Texas (a Kolbra and MKIIIc), one from Alabama (MKIIIc), one from Arizona
(Firestar II)
Things got off to a slow start on Friday as people arrived throughout the
day. But those that were there didn't wait.
{Several take off and landing photos here}
Friday evening as the sun was setting the monuments took on a deep red glow
as a back drop for the Kolbs setting on the runway at Gouldings.
{Rick's photo of Kolbra and MKIIIc with monument behind}
Back at camp the hanger flying gets into high gear.
{One of Lars night camp photos here}
Saturday morning different monuments took on that red glow to high light the
takeoff of John Hauck's Miss P'fer.
{Rick's photo of John Hauck's Miss P'fer}
As the morning progressed the fun really got going as everyone took to the
air. Those that had planes shared their airplanes and the unique geological
beauty of Monument Valley.
{Rick's photo of monument under C175 wing}
{Jim Hefner's flight photos (sill waiting)}
{Lar's flight two photos (still waiting)}
At mid-morning the wind came up and the intrepid pilots returned to earth to
visit and relax. 90 degree temps sent some into the shade of this
conveniently parked RV's awnings,
{Lar's camper awning photo}
.......and some into the shade of wings. Could it get any nicer than this
??
{Lar's sitting under wing photo}
The location couldn't be better. The scenery is breath taking and we have
the air in the Valley all to ourselves except for a few Caravans and Twin
Otters that fly tourists directly in and out of the Goulding Resort. The
airport elevation is almost 7,000 feet ASL with temperatures close to the 90
degree mark. The heavily loaded tour planes struggling into the air make a
stark contrast to our Kolbs relatively unaffected by the high density
altitude.
{Rick's Caravan Photo}
When the wind died down in the afternoon and temperatures dropped, we headed
out again. This year it seems like more people headed north to the San Juan
River, near Mexican Hat, Utah for the different scenery there. It was
great.
{Undetermined San Juan Photos here}
After flying on Saturday some of us took a 10 min. hike above the camp
ground to view the arch and other scenery.
{Undetermined arch photo}
Sunday morning most of us met at the Gouldings restaurant for breakfast and
more talk before heading back to reality.

Ed,
Your torque value is correct.
As to the engine gear box ration, remove the pull starter. Using an incline
meter rotate the propeller to the horizontal position. Again using the
incline meter mark on the exposed flywheel level with the center of
rotation. Then have some one slowly rotate the propeller through one turn
and bring it back to the horizontal position. Count the number of engine
revolutions as the propeller is turned. Then use the incline meter to
determine the position of the flywheel mark relative to the center of
rotation and the horizontal. Divide the number obtained by 360 and add it
to the number of full turns, and you will have the gear box turn ratio.

Needless to say, I was a bit surprised to see "UL 001" stamped onto the rear
of the fuselage! I bought the plane from Dennis Souder, who had told me that
it was a factory demo plane, but I had no idea it was the first Firefly. It's
a bit intimidating - a small piece of Kolb history. It had made the airshow circuits
as the Firefly was introduced. Originally, I was hoping to fly it to Homer's
on the 18th, but life has to go on it's still airframe pieces in the hangar.
Hopefully, by the end of the summer, it will be airborne with a new lease
on life. I'll keep the list posted when the first flight happens.do not archive

Bob,
Cage and serial numbers may not be the same. In my case, I believe my cage number
is five but when I called the old Kolb Company to get my serial number, I
was given four.

John, we made an enclosure for above the tanks to blend in the air coming
around the rear enclosure. I expect it does a fair job of eliminating the
drag from the back side of the enclosure. It is probably not optimum for
aerodynamics, but we compromised to make it easy to get to the gas tanks
for refueling. Here is a picture. If you are interested, I can send you a
few more pics.

Jack's method is exact, but here is an easier way. Take out a spark plug.
Take a thin wooden dowel and stick it down the plug hole. Put the piston at
top dead center (best you can tell) and turn the prop through one full
revolution. Since the A box and B box come in 2:1, 2.24:1, and 2.58:1
ratios, then after two trips down and up, the stick will either be back at
top dead center. (2:1 ratio)
Or it will make two trips down and up and then go half way down. (2.24:1
ratio)
Or it will make two trips down and up, and then down again to a hair past
bottom dead center. (2.58:1)

I understand the main reason of supporting the boom while in transit is to

Could you guys who have a full screen windshield on your Firestar
describe how you hinged it to open? A picture or two would be helpful
also.
Thanks.

Fireflyers,
I need help! I am trying to verify if my tach is correct. I have
secured
an optical tach. My problem is. How do you tell which gearbox you have
and
what the gear ratio is. My Firefly is nearly 30 mi from my house now,
so I
cant go out and look at it in the garage like I used to. I purchased
the 447
engine package from the New Kolb.. I need to figure out what rpms the
prop
should turn to equal 6300 rpms at the engine . Also the manual says to
re-torque
the heads to 221 inch pounds at 2 hours run time. My torque wrench only
goes
to 200 " lbs. I think that equates to 18-19 foot pounds. Does that
sound
right?

Eugene and Group,
The full windscreen has no hinge on the Firestar II. It is attached on
the left and flexes as it opens from the right.

some of the things I have done on my Mk 3 is to widen the back of the
cage. This keeps the airflow on the fuselage sides rather than breaking free
at the shoulder point causing turbulence and drag. The wider, more abrubt
break at the back also has an aerodynamic function refered to as the
kammback effect (sp). A lot of cars used this idea after it was noticed
station wagons performed better in wind tunnels. I also did not run my
cockpit up to the wing. There is a gap between my wing and cockpit creating
a parasol type aircraft. Padre' Pike has a similar setup on his Mk 3. I
figured I gained 3 more feet of wing plus the loss of drag at the 2
connecting points. I don't know if these ideas will help on a firestar.
Fairings on the wing strut attach points will help also if you can design an
easy to remove system. If you want to get into more work and expense you
could create different more effective wing tips also. Perhaps gap seals on
the rudder and elevators too.

ray/group,
the integrity of the kolb design was not the reason!!! the reason was
that being as nice a person as he WAS, he repeatedly did the same kind of field
fixes with his trike, and took the condition of his aircraft with little regard.
the patches to the gear leg looked like aluminum to me on Saturday morning,
the 1 inch x 4 inch chunk out of one of his ultra prop blades should have
been enough to keep any pilot in their right mind on the ground.
Your assuming that the steel was 4130 ? i first meet him in 2004 when he came
to a fly-in in his trike with; busted motor mount welds,busted muffler bracket
welds, bolts missing and another prop with a large chunk missing.
PILOT ERROR is most defiantly the cause, but the error started on the ground and
in the air long before that Sunday morning in his lack of concern for aircraft
condition. Most of us are in the "IF" category, I had him in my "WHEN" category
and now sadly i have to put yet another pilot in my "DID" category.
He was a very nice person and will be missed.
Fly Safe,

Good stuff, Woody. Wasn't it Ron Christensen who, a few years ago, built
his "Mk III 1/2" out here on the Best Coast ?? He made shortened fiberglass
droop tips for the wings, as I recall, and wasn't too happy with them.
There's a couple of un-clear pictures of them on my website on the "Gullwing
Doors" page. He went to a huge amount of time and effort trying 2 or 3
other shapes and lengths, and eventually wound up with the stock Kolb
wingtips. Food for thought. Lar.

Hey Ed:
Have been reading the diverse responses to your ratio question... they are
undoubtedly all correct, and each of the the procedures provided in them
would be fascinating to execute... But, being an intellectually
disenfranchised 'ol soldier, and certainly not a math major, it has crossed
my feeble mind that a a true deep-thinker would just go ahead and read the
ratio numbers where the stinking Rotax fairy stamped them on the rear of the
gearbox on the little raised flange just below the prop hub as the engine
was on the way out the factory door... at least that's where
she...he...it... whatever the hermans are hiring for fairies these days,
stamped it on both my "B" boxes... Both of mine are stamped "2,58 DO"
indicating 2:58 ratio... Betcha that's what you got with your 447, too...
but then, who knows... been wrong before... been married 39 years, so I'm a
quart low on credibility and self esteem anyway... (but if'n I was you, I'd
go quietly sneak a peek fer the fairy numbers before I went and got out the
calculator, pullys, coathangers, chalk, string, and smoke grenade....)

Wade,
You are correct in that the "splint" on the gear leg was aluminum,
but the 4130 steel I mentioned, and referred to specifically, is the steel insert
in the end of the struts. The left one remained in the proper fitting on
the cage, while the right one had been pulled cleanly through the attach bolt,
which remained in place. The right wing passed through the tree and this apparently
was the reason for the right strut end pulling cleanly out of the cage
fitting. A close examination of the steel insert in the strut end didn't show
any signs of stress cracks or rusted area, only the sheared path where it pulled
out of the bolt. All in all, it was a sobering thing to see what awesome forces
can be generated in even a 200-250 ft. dive straight down, with power on,
into the ground. Makes me doubly comforted knowing I have the BRS mounted.
Wade was the other Kolb at the fly in yours. Pretty nice.

Beauford,
I would have looked, but I explained in my post My firefly is 30 mi away
now and I cant go out in the garage and look. I was hoping for info like
you have given me. I did not know if it had something stamped on it or not.
I was hoping it would have it on there somewhere. That has to be the easiest
way. but if it doesn't I will still be able to do the math . I am already
breathing easier. My Thanks to You and ALL the others that took the time
to respond.

I can get about 4 gph at 75 mph and 5900 rpm (503 dual carb) on mine with
the back
enclosed and the back lift strut off ( it was a waste and extra drag
anyway) - The streamline
struts did the most. I used to have the streamlined
gear legs, they were also waste of time - but they looked good.
You should get a cleaner air flow to the prop. I never had the
"unenclosed" back section - even with my old KXP - so I don't know for sure.
Maybe your new jets will make a difference. My engine is too old (638 hrs)
or I would
try downsized jets just to see for myself.

They used to sell a kit for this but here's a picture or two.
I got the "high" sides so it's harder to get into, but
funner to fly - like a "X-Wing" star fighter - ha
