Try watermelons or cantaloupe...they don't bounce and are hard to
catch once released. But guaranteed if you had tried to catch it you'd
get the same "Ooh! Ahhhh!" from the crowd.

Subject .. Ultra Star Drag Strut
Does anyone know the year the drag strut modification was added to the Kolb
Ultra Star kits? I built one in 1983 and don't remember this fix. Did some
problem arise that caused it to be added, and if so what was it? Did it become
a Kolb mandatory item for the older Ultra Stars?
I've been out of the loop for many years but am thinking of buying an Ultra
Star because I believe it was the best aerodynamic design Homer came up with,
not the least being center thrust line, as well as other features. There wouldn't
be so many reports of stalls at engine stoppage if they were flying Ultra
Stars. He had to compromise and lift the engine because some insisted on using
it for a lawn mower, and as far as I'm concerned, there went the ball game,
or the neighborhood.
I'm 86 and live by the old saying, "If it ain't broke, don't fix it".
Would appreciate answers to these questions

Ray and others,
The Ultrastar drag strut brackets were installed because Dennis Souder found the
drag strut to be the weak spot in the wing design. He broke the wing during
an intentional flight test and discovered the drag strut had bent out of column.
The wing broke under about 6g's of force doing many tight loops. Homer installed
the brackets after that. I'm not sure of the year, but it was before the
Firestar came out in 1985.
The Ultrastar is a great design, but the Original Firestar is better due to the
steel control linkage tubes rather than cables. This would be the weak spot for
the Ultrastar as the cables take a 90 deg bend and this leads to wear around
the pulleys. The Firestar elevator/rudder cables take a very shallow bend and
never seem to wear out. The higher thrust line does not affect the aerodynamics
that much as I have flown both types.
The Firestar also has a larger diameter fuse tube and wing spars (5"), while the
Ultrastar is only 3" (correct me if I'm wrong). In the early days composite
props weren't around, so the Ultrastar props got covered with grass and were more
susceptible to nicks and dings. The Firestar prop is above the fuse tube and
does not have that problem.
I think the Ultrastar is plenty strong as Homer and Dennis have stated, without
the brackets, but the plane would have to be flown within its limits, of course.
I liked the light weight of the Ultrastar and if you think a Firestar gets off
the ground quick, try flying the Ultrastar. Nice machine and I wish the old Kolb
Company would start making both planes again. Both are very good designs.

Kolb Friends -
I'm beginning to get some friction in the throttle and choke cables on my
Mark-3.
(Cables are the standard bike cables in the black rigid housing, and
splitters.)
What's the preferred method for lubricating these?
Graphite powder? Light oil? Grease? Copper anti-sieze compound?
Thanks -

First, off, my deepest sympathies to the people involved. I hope that nobody
was hurt, and trust that the lack of mention of injuries meant that Craig
and Mr. Hatfield escaped without injury.
The aircraft sounds rebuildable, and hopefully, will be in the air again
soon. Much was done correctly, and that paid off.
There are four points that this incident emphasized, beyond the very obvious
one of having too many people in the cockpit.
1. No homebuilt airplane is a known quantity, especially when it was not
built to the plans - and most people incorporate at least a few changes.
There should be a period of testing and inspection before it is released to
routine operations like take-offs and landings. This initial period should
explore the flight qualities in various attitudes and speeds, the propensity
for flutter, and the likelihood that a systems issue may surface. This is a
very hazardous time and great caution is warranted.
The FAA has an excellent guide to flight-testing on-line, and you can buy a
hard copy from the Superintendent of Documents. Do a search for Advisory
Circular AC 90-89A.
2. Non-destructive inspection techniques are as close as your copy of the
yellow pages - maybe even closer, on the web. Costs are reasonable and the
capabilities these days include the ability to inspect welds, find hidden
flaws in the parent material, and even find flaws under the surface of raw
material. If you have flight-critical parts that you do not feel has had
proper quality control, or that you're unsure of, it may be worth having
them inspected.
Some useful types include dye penetrant inspection, magnetic particle
inspection, ultrasonic inspection and radiographic inspection. Usually you
won't need to know all that much about it yourself - just let the inspector
recommend the appropriate inspection.
3. If a person makes changes in the design of a plane, those changes need
additional qualification to be safe for flight. Sometimes a simple
functional test is all that's required. For other changes, static, dynamic,
ground or flight testing is more suitable. Still other changes should be
carefully analyzed.
4. It is difficult to maintain a high pilot skill level while building an
airplane. Not many of us can do that, me included. Prior to flying your
Kolb, currency is mandatory in taildraggers and in very light airplanes. If
you're a private pilot or higher, you'll need an ultralight checkout.
I don't intend any criticism here of the people involved. I just wanted to
mention these lessons for the benefit of others.

P.S. No, I haven't flown it yet - I need an ultralight checkout first.

Fellow Kolbers,
As you can expect, I spend a great deal of time on the phone asking questions and
seeking help with the construction of Ms. Dixie. Mark German has helped me
so much with minor to major mods to the Kolbra. As well as Jim and John Hauck.
Mark sent me some photos today from his week long stay (due to weather) at an
inroute airport. I felt that you all may enjoy looking at them and hope Mark
won't mind. His Kolbra is a true marvel. As you can expect, when building a airplane,
you stumble across someone that has created a masterpiece and the cost
goes through the roof! However I don't mind spending the extra bucks to have
a really nice airplane that I hope myself and family members will have around
for years.
As mentioned in a earlier post these mods or changes need to be tested and trust
me we will. However the changes or mods we have made to our Kolbra for the most
part have been tested time and again.
Flaps on our Kolbra is a first and we are going for it. I spent a good part of
an hour on the phone today with Steve Bettor that is designing the floats for
TNK and I am very excited about this project.
Thanks to Matt for this list as it is a must for first time builders like myself.
This next week is going to be very interesting with the new float testing. Stay
tuned......
This past Monday I flew in my first open cockpit airplane...WOW makes me want a
firestar!
Any her are the photos.......

Dennis,
I got a can of cable lube from the bike shop. It has a device to seal
around the cable and housing then forces the lube though the housing to the
other end. This does not take the place of removing the cable to inspect
for wear.

I have run my low time used 503 DCDI oil injected motor for about 7/10s of an hour
now using a 50 to 1 mix in the gas tank just to be safe and not burn a piston.
The oil line to the rear carb is filled with oil, but the line to the
front carb is not . I can see small spurts coming from the pump but would have
expected the line to be filled by now and the engine smoking or fouling plugs
due to the extra oil in the gas mixture. I would like to keep the oil injection
system but am wondering if I may need a new pump. The motor has only about
3 hrs on it, but sat unused for some years. It runs great with good temps.so
far. Any suggestions? Also, thanks for the replies on my gap seal question.

| Subject: | Ultra Star drag strut mod. |
--> Kolb-List message posted by: "Richard Swiderski" <swiderski@isp.com>
Ken,
I don't know when the change happened, but the brace is not required
for normal flying. Dennis had to cut the elevator stops off to get it to
dive fast enough & in order to do a snappy enough pullout to exceed the 6 G
limit. Most normal people won't find themselves in that situation.
I'd be more concerned that your inboard spar has a steel ring in its
edge similar to the top of the boom tube, if not it will go egg shape when
wing torques & you'll loose banking effectiveness. The rudder aileron cables
will start to fray at 100hrs. It's a easy fix, just put 3" pulleys at the
90 bend or break up the 90 degree bend with 2 good size pulleys. Do not use
stainless steel cable as it is more brittle & breaks easier, use the steel
cable with the thinnest bundles of wire as it is most flexible. You'll
never be bother by then again.
Your wing & tube are identical to the early FireStar.
Regarding 50" prop, I inlaid aluminum p-tips in it & got a 12%
increase in top speed, max climb; plus 12% reduction in fuel burn & 12% less
rpm needed for a given cruise. And those aluminum tip sure did cut weeds
better. I'm guessing that prop was equivalent to at least a 60". It was
also much quieter.
I have some plans I found yesterday, that converts the rigid gear
into a flexible bungie like a Taylorcraft. I added 12" to their length
adapted a Rotax B box to the Cuyuna & hung it down. This gave me room for a
60' prop which also put p-tips on, but similarly. I only got 10% increases
Give me a call, 352-307-9009, if you want to discus anything.
