I checked the original post on YouTube. The following are quotes from the person
that posted the video. Best first-hand information that I can find to make
a guess at what really happened and even this might not be the true facts.
>From what I surmise is a faulty repair was made and lack of good training and
mentoring. The last quote implies that the gear failed on taxi tests. He then
continued and got airborne unexpectedly. Hate the term Kolb drop. We fly a
low inertia, draggy airplane and have to be aware of that, then it gets easy.
This is what allows a Kolb to land and takeoff places that very few other planes
can even attempt. Why I got one! Saved my butt in an hayfield in Texas!
> nope landing gear failed
> 1st time he flew the plane and he did not tell anyone. my uncle gave him heck(the

not too smart).

Mike, Stupid Question # 2
Would the finished fairing have a larger ID than the plaster mold (1st
build up)?
Seems like you would have to extend the finished fairing out beyond the
edges so it would meet the strut cover or whatever it contacts. How is
that done if your doing a layup inside your mold?
Note: 10 layers of glass mat ( video), if I used that much my part would
weigh 100 lbs. and be an inch thick.

> John Bickham
John B., Ray, and others,
That's what I thought, too, as did Bob B. Both of the ingredients of a guaranteed
failure; lousy construction of an aircraft, and an untrained goofball.
He is lucky he lived to tell about it. I hope he got proper instruction, if he
continued to fly.
This makes me wonder about the UltraStar frame you have, Ray. As I said, I know
of an UltraStar frame that was assembled with rotten quality control. I have
NO doubt that this plane would likely have crashed, if it were ever finished
and flown.
Ray, how certain are you that the frame you have is "good, and of aircraft quality"?
Have you, or a professional welder, done a thorough inspection to make
sure the frame is as solid as you think it is?
I recently heard a comment from an FAA Crash Inspector say, "a catastophic crash
is never a spontaneous action, but rather, it is a culmenation of a series
of events and decisions that lead up to the crash." (or words to that effect)
Having crashed just like this moron (yes, I was stupid, stupid, stupid!!!, and
even worse, I have it on film!!), I have learned not to assume as much as I
used to. "Now", I rely on training, and better quality control. It was an expensive
lesson, but I believe I learned from it! Hopefully, I am not near as
stupid!!!! In my case, I got hurt more than the ultralight!
It is my belief and understanding that Kolb aircraft are quite possibly the best
flying light planes there are. They do, however, require standard aircraft
quality construction, maintenance, and equally important, a "thinking" person
at the controls. Those Kolb pilots with hundreds (or higher) of hours flying
them probably agree.

Hi Vic,
Again, nice observation. If you shaped a perfect fairing (on your plane), and
you took a mold off that perfect fairing, and then you built your part on the
inside of that mold, your finished part (fairing) would be slightly smaller,
not larger.
With this understanding, that your part will be slightly smaller (by the width
of you glass layers) you may want to build up your sculpted prototype, with
extra tape, etc.
This is especially important if you are building something that has an opening,
like our fairing. Our fairing has two area of interest...the part that fastens
to the fuselage. A tiny bit smaller, or bigger would never be noticed.
But the part that has a hole, that slips up the wing strut, won't fit unless you've
made that opening a little oversize". No doubt, Uncle Craig allowed for
this.
I know it seems to get a little confusing, but if you take into consideration
that male, female, male, undersize, oversize, etc., etc. changes, it really isn't
hard.
Example, if I were to make that exact same part as Uncle Craig made, I would
wrap the wing strut with...oh, about 3 layers of duct tape, since duct tape is
"close" to the thickness of fiberglass cloth. 3 layers of tape gives you room
for 3 layers of glass. So, now, when you build a mold around that wing strut,
the hole in your mold will be oversize. Right? Therefore, when you start
putting in the layers of fiberglass, or carbon fiber, inside your mold....you
will be closing in on that original wing strut diameter (prior to the duct tape).
The portion of the mold near the fuselage doesn't matter if it's 1/6"-3/32" smaller,
you'd never know. But the part of your fairing that needs to slide up
and down the wing strut won't fit, unless you accomodate for it.
The video of mold making was just that....only the mold. That's why the 10 layers.
He was making a mold, not the finished part. With this mold he made,
he can now apply plenty of mold wax, then gel-coat, and then 3-4 layers of cloth
(whether it is carbon fiber, E glass, S glass, etc.) Because his mold is 10
layers thick of fiberglass, it should last for years, and hundreds of "take-offs".

A factory frame? First I've heard of this, and it naturally makes me
nervous. What were the problems, what should i look for?

UltraStars don't have bungees, just a rigid gear, not even the spring steel
gear of the later Kolbs... the only shock absorption is the tires, so you
have to land it gently. I watched the previous owner of my plane break a
gear in a landing that looked no harder than the one on Youtube (to my
friend's credit, it was a dead stick landing during his first solo in the
plane... he got it onto the runway but had no speed left).

Dana,
No, not a "factory" frame. The very early UltraStars could be purchased with
unassembled,
weld-your-own, frames. You bought the chromoly and plans, and did your best!!
Only SOME
people's "best" wasn't very good.
It might be that in order to insure a more safe, and accurate fuselage, that
Kolb Co. made
pre-built frames standard equipment.

Thanks Pat. I hope to enjoy a few more years of agility to enable me
to really enjoy retirement.
Possibly we could meet way ?? No, not mid-Atlantic, even the
DustBuster (my 16' center console boat) won't go that far, but I'm
tentatively planning a trip to Newfoundland/Labrador next year. I just
know you won't be able to resist THose bright lights. :-)

While not stock set-ups, I personally know of 3 different Ultrastars that had bungee
suspension systems on their mains.
The attached images are of a very highly modified one (used to belong to Richard
Swiderski of this group) with a bungee system.
Sorry I don't have images of the other two.
