Subject: | Re: vortex generators |

They are vortex generators. The minimum equipment list for virtually all jet transports
allow a certain number of VG's to be missing on a given side. I think
having more than several missing can effect the control. You are supposed
to check them during pre-flight. The captain should have known that!
"After all the discussions of VG's here on the list i was looking at the heavy
iron.
The Boeing i was on had what looked like VG's on the wing inboard of the
engine nacelle I asked the Capt if they were indeed VG's and he wasn't sure...
Any big iron drivers out there?? were they VG's or just "stuff" on the wing"
I installed 46 of the Harrison Design (landshorter.com) on each of my Firestar
2's wings, at just about the same distance from the LE and with similar spacing.
Stall speed went from 35 mph indicated to 30 mph indicated with nicer handling
right up to the stall. Also, there is a bit more float during roundout,
and less tendency to drop hard on the gear if you don't get things right. It
does take a bit more power (100-200 rpm) to hold a cruise of 55-60 mph than without
the VG's. I'm sold, and will leave them on.

I was at the Fly-in on Sat talking with the owner of a nice looking Yellow
Firestar who was a member of the MTUG group I think and also definitely knew
a lot about welding.... in fact I think said he worked as a welder.
( always remember everything except the name ? ? ? ...... )
Anyway, he pointed out the ultrastar as a basket case and said he cited the numerous
bad joints, cracked welds, and obvious kludge repair job on the landing gear
that had been broken and had had splints applied with radiator clamps to
the owner.
He said he suggested to the owner to take a cab home and declared to me that
guys like him give ultralights in general a black eye.
Now a few days later I hear of the very same plane going down with
structural failure. Too too bad. Doo doo happens if you let it.
It was an attractive plane from a distance but this guy's attitude
is what killed him, not the rust.
For whoever has inspected the wreckage, it would be useful to know the
exact details of what failed and how.
Thanks,
Scott

data indicates the Kolb had been recently purchased from someone in Chattanooga,
TN by a Mr. Primm who had cleaned it up, added a nose cone and painted everything.
He failed to see a rusted out area somewhere on a wing strut and that
is where it failed. He deployed a ballistic chute but was too low for it to
function. These are the facts I know at the moment. When I get more I will add
them.
I was at the flyin on Saturday and inspected the UltraStar, thought it
looked good and waited around for quite awhile to talk to the owner since I
have an UltraStar, but had to leave before he showed up.
Hidden rust can sure ruin your day.

I ended up with the top of the stabilizer leading edge slightly higher than
the boom tube. I left the original bracket on the tube and mounted the 4
hole adjustable bracket directly above it. I am extremely satisfied with
the results. If you use the modified bracket by itself, make sure the top
hole will allow the top of the stabilizer leading edge to be slightly above
the boom tube.

Not familiar with Kendale bearings... new name to me.
The conventional wisdom is to idle the 447 (and I believe all of the
2-stroke Rotaxes without clutches) at the lowest speed you can get it to run
smoothly without experiencing any "chatter" in the gearbox... on the one I
fool with, I have found that proper fine-tuning of the idle air adjustment
screw is critical to getting it to behave properly. Mine will run smoothly
down to about 2350 on most days... 2400 on others. As you know, you should
make sure you get it up to full operating temp before you try to adjust it.
Worth what ye paid fer it... good luck.

All,
I checked with the folks at Tullahoma airport and they thought the wreckage
had been removed back to Chattanooga. I wanted to look at it because there
has been some confusion about the point of failure and where it was.
A point of interest is that the pilot never pulled the activating handle
of the chute. It was found remaining in it's holder. Unfortunately, he couldn't
have actuated it. He had failed to remove the safety pin that restrained
the activating handle !! The line connecting it to the rocket apparently
stretched when the wing folded and pulled the pin, activating it. Too low to
save. He might have survived if he had been able to pull quickly when the failure
occurred. Another reason to always preflight, preferably with a check list,
and train one's self in how to react quickly in emergencies.

Ken, All.
Here in the UK we allign the horiz stab as per the blue prints and it works
just fine.
Initially on the Classic when CAA approval was being gained it was
established by the test pilot that when the top of the stab was mounted
level with the top of the boom tube there was little pitch stability when
the a/c was in a dive, (this is known as divergence) and pre stall warning
was almost non existant.
The cure was to lower the L/E of the stab, and on the Xtra it has been
lowered even further.
For the UK approval we had to conduct a formal and demanding flight test
program and no problems were found when the stab was fitted as per drawings.
Your problem may well lay with an out of CG aircraft (tail heavy) or the
trim system incorrectly adjusted.

Richard, Steve & All,
Everything is a trade off. Maneuverability & stability are at odds
with each other. Where you want to be on that continuum is a personal
choice. But if you add dihedral to a Kolb, you will compromise some of its
maneuverability, cross wind landing will be among the compromised.

No the Firestar actually flies very sweet, Ed took it to a local strip
yesterday and let a local airplane maven fly it (This particular guy is an
A & P, IA, ATP, Corporate Pilot, and owns TEN homebuilt/ultralight
aircraft!!!) and his response was that it was delightful, and he wants one.
And he said it was much more responsive than the current Hawk Classic. It
will fly hands off very well, but as long as you give it a good dose of
rudder, it turns as nicely as you could ask.
Maybe if I ever get off my inertia, I might try adding some more dihedral
to the MKIII. On the other hand, I don't care that it is unstable, but I
guess that stability is a good thing. I like the MKIII as is, but I suppose
I would like it better if it would fly hands off and still be as agile as
it is now - why not?

Subject: | : Kolb-List:Thrust Angle Relative To Wing |
--> Kolb-List message posted by: "Richard Swiderwski" <rswiderski@earthlink.net>
Rusty,
I was going through some old notes & ran across a comment from
Dennis Sounder that I wrote down regarding how to rig the thrust line angle
on the SlingShot. He said with the wings at 5 degrees incidence, the thrust
line should be horizontal. My wings are off & so is my engine. How does
that compare to raising the rear mounts 3/4" as was suggested earlier? I
will need to nail this issue down myself, so if you or other SS owners have
any input it would be appreciated.
Also, I have heard that the fuselage tube is horizontal in level
flight on the SS. Can anyone else confirm this?
Lastly, if anyone is measuring the SS's angles of incidence, could
you check what the difference is between the wing & the fuselage tube?
Thanks.

On my Firefly I used a marine style ignition kill switch. I attach the
igniton clip to the BRS remove before flight flag. You have to remove the safety
pin
on the BRS in order to activate the ignition. When you pull the clip after
you flight you have to put it somewhere so you may as well put it back on the
BRS. At any time you are fooling with the prop you can always look at the BRS
handle and confirm that your ignition is not hot.

far as CG was concerned. I consulted with the factory and an aeronautical
engineer prior to my raising the leading edge of the stab and both concured
with the move. I have stalled the plane and recovery was straight forward
and acted just like my Firestar KXP. I also looked at the FS, FF and MK III
Classic and their stabs are mounted with the Stab LE raised. I can not
explain why some MK III X planes fly with the Stab as the plans dictate and
others don't but I do know mine flies very good now that I have moved the
Stab.
You do raise an interesting question about the pitch stability in a dive.
Why would it be different than straight and level?

Scott/ group,
I was the owner of the yellow firestar that talked to you and Mr.
Primm on sat. It was a basket case, there were at least 4 reasons for it being
grounded,landing gear rigged up,large prop chip,no gap seal,no w&b,homemade
parts. the last i heard was that the strut failed, these looked like the landing
gear tubes( ends crimped in vice and split on sides) that failed upon his arrival.
he also owned a trike in about the same condition.
it might have had something to do with the fact that he only had about 3 hours
in this plane before he flew a 50 mile x-country or, that the conventional
3 axis was exactly opposite controls that he was used to.
Mr. Primm was a fine man, very pro-active in the local and regional ultralight
community but, sadly he did not take the condition of his equipment nor the advice
of his peers serious enough and it cost him the ultimate price.
Fly Safe,
Wade Lawicki

DNA: do not archive

Dear Lister,
Please read over the Kolb-List Usage Guidelines below. The complete
Kolb-List FAQ including these Usage Guidelines can be found at the
following URL:
http://www.matronics.com/FAQs/Kolb-List.FAQ.html
Thank you,

******************************************************************************
Kolb-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the Kolb-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the Kolb-List in the manner described below may result
in the removal of the subscribers from the List.
Kolb-List Policy Statement
The purpose of the Kolb-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.
