The air bleed that has already been mentioned would be the first check. Is
your oil tank mounted higher than the pump?

Take a look at the following website for how some do it on inverted 503 installations
in Challengers. It may or may not work on a straight up engine.

Hi Paul,
Did he build or buy this Slingshot? If he bought it, it was the Slingshot
built by John Russell and the one that I got my 912S off last September. I
thought a guy in Canada bought the airplane John R. built. Very nice
airplane either way.
I will be out of town for a couple of weeks on a bowhunting trip in New
Mexico. Ya'll take care and of course be careful and safe in all your
endeavors.
Later,

--> Kolb-List message posted by: "Etheridge, Joel" <Joel.Etheridge@FMR.COM>
Good Morning,
I saw you guys talking so I thought what the heck...I'll jump in. I am
in the process of buying an aircraft. I have narrowed it down to the
Kolb Firefly or a C-150. I am really excited about the Firefly, but am
really concerned about getting discouraged in the building process and
not finishing. I am not a world class metal worker or mechanic. But I
have done stuff like installing a new engine in my old pickup, always
fixed my own vehicles, etc. I have never done any metal work and my
fabric work has been limited to ordering the little Poly Fiber kit that
Aircraft Spruce and Specialty sells to get an idea on how fabric
covering works. I have been to Oshkosh for the last two years and gone
through their metal workshop, their fabric workshop, and their welding
workshop
A couple of questions for any out there who have experience building a
Firefly:
- What is a realistic build time for the Firefly?
- What have you liked and/or disliked about the Firefly?
- What was the most difficult part of the building process?
Your input appreciated!
Joel Etheridge

--> Kolb-List message posted by: ray anderson <rsanoa@yahoo.com>
We just transported my Ultra Star 900 miles from MN to Tenn. on a flat bed trailer.
Wings and fuselage were wrapped with stretch wrap bought at a Lowes type
store. Approx. 18 inches wide, 1500 ft. roll for $7.95. A couple sheets of 1/4
in. thick foam, 4'x8' , bought at the same place, laid on the trailer bed. The
wing panels were wrapped in movers blankets (U-Haul) and wrapped in the plastic
wrap (Not too tight as it is stretchy) The two panels laid on top of each
other with a couple of light wood frames between to separate them. Every thing
securely lashed down and it arrived home safely. Cruised at 55-65. Had enough
plastic wrap left over to wrap mashed potatoes and fish for 5 years.
A word about John's description of his fabulous Alaska trip. He mentioned the Will
Rogers/Wiley Post memorial and stated that the accident was a stall type event.
If my old memory recalls correctly, and I remember the day and report of
the accident, I believe they struck a partially submerged log or piece of timber
with one of the pontoons on take off and the aircraft cartwheeled. Wiley,
as you probably know, only had one eye and perhaps lack of perfect depth perception
contributed. We'll never know.
John, since you have a personal involvement in having viewed the scene of the accident,
you might be interested to know that the wicker seat Will Rogers was
sitting in at the time, is on display at the Stagger Wing Museum over in Tullahoma,
TN. just a few miles from here. It was recovered from the wreckage by a
coast guardsman, I believe, and one of his relatives gave it to John Parris to
display in his Stagger Wing Museum at the Tullahoma Airport.
I let the cat out of the bag mentioning I remember the day of the accident. I was
about to make my first solo flight in a Curtiss Wright Jr. and anything aviation
got my attention. ( I actually saw Lindberg fly the Spirit of St. Louis).
And yes, I guess I'm probably the oldest Kolb driver around at 86. Built my
first Ultra Star in 1983, and don't talk back to your elders! (your mama taught
you that!) The Ultra Star was and is still the best overall design of the Kolb
line !!! Homer did it right the first time or he wouldn't have released it.

Getting ready to shut down and go to the garage to work on my Firefly.
I installed the nose pod ,seat belt and instruments yesterday. Working
on the full enclosure today.
My guess is that you are miles ahead of many who have successfully
built Kolbs and other UL type planes. Matter of fact; I traded a
beautiful Zmax for the Firefly project that I have been working on for
about two months. The fellow who built, the max, had never done anything
like it in his life. All of the glue joints were first class(that I could
see:-) ) The engine and instruments were mounted very well. And ---most
importantly--whether it flew or not---it had an excellent paint job!!:-)
I was the test pilot and put about 70 hours on it before I traded it
for the Firefly project that I am now working on. Word of caution--be
careful when taking over a project. I spent the first month going
backwards!
If you chose the Fly; then think about the new "unofficial model" with
the Firestar 'H section" and single ,streamlined, lift strutted wings. I
saw that down at Brians quick build hanger at Chestnut Knolls Airpark .
Really nice. And a big plus with Kolb--they , the factory guys--Donnie
and Travis--are just great to work with. Same with Brian who answers
technical questions. And his sidekick whose name escapes me. Randy?
You will learn a lot along the way. If you can spent a bit working on
it most days, then you can build it in a few months. Mostly assembly
work. A wing can be put together in an couple of 8 hour days once you get
the hang. Build the tail feathers first. You will find the cheap screw
ups to be had back there!! :-) Two leveled and very sturdy saw horses
are all that is needed to build a first class wing.
When Fireflyers say "you are really going to like it"--they are
telling you as much as is wise to print on the net!! :-) Herb
ps come to the fly in next month and watch and listen. You will not hear
a negative word said about Kolbs and you will meet some first class
folks !

The firefly is about as easy to build as anything I have seen....I got a
partial built.(empennage done to covering)in october..had to tear apart and
redo everything, and still was ready to paint by the 1st of the
year....spent 2 days every weekend...and 2 or 3 eves a week in the
shop.....it just goes really fast.
here is a link to my builder site.

Joel,
>- What is a realistic build time for the Firefly?
It took me almost two years to get mine ready to fly. A lot of time was
spent trying to figure out how to keep strength up and weight down. I build
a paint room, and a false wall on which to build the wings. I was too old
to lean over or crawl under to pop rivet the wings.
>- What have you liked and/or disliked about the Firefly?
With a little tuning, the FireFly is a fantastically fun plane to fly any
time of the day when the winds are below 20 mph.
Four complaints. 1) Construction instructions did not mention landing wheel
camber. Took me a while to figure out why the FireFly was so sensitive on
the ground and what to do to correct it. 2) Fifteen inch chord ailerons were
impossible. I changed to nine inch chord ailerons, and drilled extra holes
in the lower aileron "Tee" bar to limit aileron travel to 20 degrees. It
changed the ailerons from impossible to move at cruise to two fingers on the
stick light. After I added another 3/4 inch of streamlining to the ailerons
they have moved back toward the heavy side. 3) The front seat tube is too
high and it cuts into the bottom of your legs. To get around this I took
the seat bottom loose from the rear lower seat cross tube and made a true
sling seat. This and padding has helped a lot. 4) Flaperon handle and
original de dent system was impossible to use with twin shoulder straps or
five point belts.
>- What was the most difficult part of the building process?
Building flat wing panels. Using the wall and a tygon tube water level, I
could level the main spar tube on the wall. Used three plumb bobs. One
keeps the steel rib true and the other two maintain wing flatness over the
leading and trailing edge wing tubes.
Rigging the wings to the fuselage. Made an eight column water level out of
tygon tubing so that there would be a column mounted on each outer and inner
wing corner. All tubes were connected to a bucket. By raising and lowering
a bucket one could move the water in all the tubes at the same time. A
plumb bob was used to vertically true up the cage. The outer wing panels
were adjusted until the front of the wing was true from side to side and
from front to back with the desired dihedral, and with the distance from the
tail post to the outer rear wing tip measuring the same. At this point the
hole for the wing spar pin was marked for drilling.
To save weight and reduce a little drag, I butt fitted all 5/16 diameter
tubes. This made it a little more difficult to build flat ailerons.

Hi Ray/All:
Looks like the Grey Baron has some competition in the longevity class.
Not much hard info on the accident of Wiley Post and Will Rogers.
Most of it is speculation. Only witnesses were Eskimos at the hunting
camp at the lagoon, from what I could glean from the internet.
Thanks for the info, Ray.

I built a MKIII but the construction is the same but take slightly longer.
The work shops at Oshkosh are great and will get you through the
construction process. The instructions that come with the plane are good and
we are always here if you have any questions. I set a goal of 1 hour per day
(averaged fairly close) and had the plane ready in two years. My non
standard engine added another year but the standard engine packages are a
easy bolt on operation.
You are the variable on the building time. Some builders will be flying in a
few months, most in a year or two. There is a vocal one in our group that
that has been building for what 8 years and you will be done before he is.
The main trick is to follow the plans and don't make improvements. Ok
everyone makes improvements just don't get carried away with it.
If you are considering a C150 why not a two place Kolb? The C150 is a bit
faster, can be purchased for less than a kit, is a very dull flying
airplane, and like all general aviation airplanes will cost you a bundle at
each annual.

This came from USUA:
When the USUA 3rd Party Insurance Program was announced In December
2003, only USUA registered airmen and vehicles were recognized as
eligible. This is no longer the case. As a result of ongoing dialog with
First Flight Insurance Group, USUA members who hold Ultralight Pilot or
BFI registrations with ANY FAA RECOGNIZED ULTRALIGHT AIRMEN REGISTRATION
PROGRAM (USUA, EAA, ASC), and/or have registered their ultralights with
any said group, are now eligible for the USUA 3rd party insurance
program with NO ADDITIONAL RE-REGISTRATION WITH USUA REQUIRED.
Additionally, USUA members who are FAA registered Sport Pilots flying
FAA registered Light Sport Aircraft under 992 lbs gross weight, with a
power off stall speed which does not exceed 35 knots (40 mph), are
eligible for this policy as well.

Thanks guys for all the comments. Paul I was suprised
when I say them on list. John Cooley is correct I am
the guy from Canada who bought John R's slingshot
airframe. I can confirm what John said about all the
engine discussion. I had numerous conversations with
John R. and he said the Slingshot with the 582 is
more fun than with the 912. I have never flown with
a 912 but I can certainly say the 582 is a blast.

--> Kolb-List message posted by: "Richard Swiderski" <swiderski@isp.com>
Rick,
I hope it works well too. I sure can't say it will not work. I do
know 2 big companies that used them in planetary configurations & they
failed after a couple hundred hours on one & fifty on the other. There were
hundreds of the 1st & a few of the second, both were discontinued. Its an
attractive solution that I also almost used on a twin engine 377, single
shaft setup on my old UltraStar. They obviously work well for a short time,
and if designed properly, they may very well work reliably for extended
periods. In my limited experience, sprag clutch dampening has at least
shown itself to be easily over estimated in its load capacity and/or
longevity. All the time proven designs I can think of use rubber donuts,
with the exception of the Rotax B drive which uses a friction/rubbing
method. Are there any high time redrives on the market that use sprag
clutches for vibrational dampening? ...Richard Swiderski

I certainly have my hopes up but I don't want to trade a silky smooth engine
for a reliability problem. The vibration isn't bad, just not as smooth as a
direct drive engine and certainly not as smooth as a free revving engine.
Steve Bennet at Great Plains Aircraft was telling me at Oshkosh that one of
his customers put a sprag clutch on his 2 cylinder VW and has had great
success. There is company called Aerowing that is working on a sprag clutch
that also serves as a 3 inch prop extension for Rotax pattern prop hubs.
Also seems like there is a least one of the Subaru PSRU manufactures that
uses a sprag clutch. The Valley guys seem to confident they can make it
work, we will see. If they were that bad seems like all those people
wouldn't spend all that time and money to make it work.
Valley Engineering tells me that their wood props (they own the Culver Prop
company) run real smooth on their VW redrives and has offered to "give me"
one to try out. If this doesn't pan out I will take them up on it.

Kolbers,
My Firefly will be 3 years old in November, was built by Brian when he
was at LIghtspeed and he used 3M Bookbinding Tape for the Flaperon Gap
Seals. Recent inspection revealed that the tape has finally failed and
needs to be replaced. I was so pleased with the simplicity and
performance of that system that I will be replacing the gap seal with
the same bookbinding tape.
I did a Google search and have found the 2" tape for $5.89 for a 15
yard roll at the following url:

Well, I took the papers and personaly delivered them two weeks ago ,
so if anything was wrong it could be straightened out right then...
They said things looked good , so I was waiting for the guy to tell me when
he was coming to inspect.........Finally I called him , he said some paper work
was wrong, didn't they call you.......NOOOOO.....
Does this sound right....He wants to do the W/B with a "standard" pilot weight
of 170 lbs ????? I told him I weigh 190 (minimum) and that this is not a
rental aircraft , The only person flying it will be me.
He also said....BATHROOM SCALES???? ( 5 )
And I'm suppose to also turn in a 40 hr flight test plan...
Any of this sound right to you guys ???
Hope someone has some HELPFUL answers....Mike

Sounds like your "inspector" needs to brush up on his weight and balance
realities. Seems that adding pilot, cargo, and fuel weights from an empty
aircraft figure makes more sense. Perhaps he is just checking to see if you
can do the math...?

Mike
The inspector can do pretty much what they feel is necessary. The inspector
I had did almost nothing.
The FAA uses 170 lbs as the standard weight for calculating weights for
airliners but for our planes that makes no sense. Don't argue with him give
him the W& B for 170lbs but I would figure the minimum weight for aft CG and
the maximum pilot weight for the forward CG or maximum pilot weight for
maximum gross weight if it is less than the forward CG weight. Also check
these CG ranges with full and no fuel. Check the weight and balance
calculations for a Cessna or Piper they give you the forward and aft CGs and
the moments for passengers, luggage, and fuel that you use to determine if
the result is within CG. There is nothing about a 170 lb body.
I wouldn't have told him I used bathroom scales but since you did, explain
that there are all kinds of bathroom scales and you used the high accuracy
balance beam scales. Or you calibrated the spring scales with a similar
known weight just before you used them. You did it this way didn't you?
Hey the guy sounds like he may be trying to do it right. After all this is
can be a dangerous sport and the most dangerous time is on that first
flight. You need to have a plan. Most of us didn't have to give the
inspector a copy of our plan but it should be well thought out. Hopefully
your inspector will give you tips to improve on it. I only had to draw a
circle on a map to document were I would be flying.
Hope this helps.

Richard
You have got me thinking. I have read a article about not using sprag
clutches due to reliability reasons but it was written by someone that
doesn't sell them so I figured they might not be very objective? I have been
enough of a test pilot all ready and don't feel I need to do any more. If I
go with that option it will be only after there has been considerable
testing "by someone else". My redrive builder has another less risky option
that they are also pursuing or I will just go to a two bladed wood prop. I
really didn't want to go back to a wood prop but?
I have a working solution now but I would like it smoother. I don't have to
do anything now and I don't want to create problems. Decisions decisions.

Mike,
I hope you didn't take you paperwork directly to the FAA! Your better off
with a DAR that will charge a few bucks to do the inspection and work with
you directly. I live in Barnesville. Mn and had a DAR from south of
Minneapolis come up and do mine ( I don't remember the town off hand, I'll
have to dig out my paperwork). He had me send all the paperwork directly to
him. He indicated that sometimes things end up on the wrong desk and with
the wrong people if you send it or take it in directly. I sent all
paperwork to my DAR, he checked , then took it to the FAA with his blessing
once everything in order. They then sent it back to him with the go ahead to
inspec.
If your interested, send me a note off list and I'll be happy to help you
out. I was given a 25 mile circle at an airstrip of my choice (and his
approval) for my 40 hour check out.
If you call the FAA and tell them you are building an experimental aircraft
they will send you a packet, in that packet there is a booklet with a
"suggested plan" tips on writing a plan for the first 40 hours. I know this
information may be a little to late but it was worth a try.

Guys,
County Engineers around here have done a real good job of designing lots of
washboards for our many unimproved roads. These raise havoc with trailered Kolbs.
I have supported the wings a number of ways, but it did happen - the wing
fold tube coming out of the boom tube broke. I had it welded by a real good
welder and we matched the break points and put it back together exactly as it
broke, hoping everything would match up. It doesn't. Though everything looks
the same, the tube now seems to be about 1/2 inch too far forward. I've pried,
cussed, pushed, etc, and was finally able to match the wing tube to the boom
tube by removing one rivet and really pushing forward on the wing. This ain't
a good way to go. Any ideas????
