| Subject: | Required structural modification needed |
Hi all,
I am new here, I am from France, 45 years old, glider pilot and hang-glider pilot
too.
I just find a used Kolb Ultrastar who was buy in 1987 (kit) an finished in 1990.
I 'll get it and see it for the first time on mid november.
I want to ask if there is required structural modification (ie wing drag strut)
since this date of built to check the plane and see if I need to make re-inforcement.
Thks in advance.
Have fun fly.
Jean

Jean,
From the UltraStar manual:
"The UltraStar was successfully flight tested to 5-1/2 G's without this
brace. To obtain this loading requires a steep (about 45 degrees) high
speed full power dive to 90 mph and an abrupt pullout. For normal flying
the brace is not necessary. With this in mind you can decide whether or
not you want to add the brace."
My UltraStar does have the brace, but if it didn't, I wouldn't hesitate to
fly it anyway, and add it at such time as the plane needed to be recovered.
You can see the brace if you cut a slit in the fabric of the wing root and
shine a flashlight in there. This is a good idea anyway, to inspect the
inside of the wing and make sure everything is as it should be. There is a
Kolb UltraStar Yahoo group <http://groups.yahoo.com/group/KolbUltrastar/>,
and in the files section of the group is the UltraStar manual. In the
manual, between "ailerons" and "tail", is a description of the brace, as
well as a drawing, so you know what to look for.

Hi Russ,
mine is inside but still, as it is on a farm, subject to bird droppings,
mice, voles, bugs up the pitot, rabbits or badgers digging up the floor etc
With VG`s on wing coverings have to handled gently too. The only drawback.
Cheers

Hi Dana,
Ho you don't know as I am feeling light!!! It is a very good new. Now I can
check if this modification is done or not. And if it is not modified I just
fly gently as I know the VNE speed of 75 Mph. Acrobatic is not my goal :)
Just another question about the best glide ratio of this Plane:
Even if there is difference between each Ultrastar, what is the best glide
ratio speed on it when engine is off?
Happy flying!
Jean

I've never seen it published, nor have I tried to measure it, but like most
ultralights it should be pretty slow.

I purchased the 6 gal tanks from TNK last winter and have since used them
for about 40 flight hours. I too have encountered some sagging (caving in)
of the bottom sides, at all fuel levels. However, I would not characterize
it as severe and I have not had any indications of it becoming a problem. I
have used only unleaded ethanol-free fuel in them until about one month ago,
due to a change in its availability. So, in my case, ethanol was not a
potential contributor.

Subject: Kolb-List: Six Gallon Tank
Kolbers:
Due to some other factors, I had not dragged the Fly out of the trailer for
about two months. I did so on Sunday and found something interesting.
The six gallon tank obtained from TNK a little over a year ago has developed
noticable bulging and sagging in the bottom half of the side walls. It
contained about five gallons and when pressed it felt "flabby" and a lot
more flexible than it did when first installed.
I will replace it with a standard five gallon thick-wall tank before I will
be willing to fly the airplane again... In its present condition, this tank
looks to me as if it could easily split open.
I called Travis and asked if he had heard of anything like this with the
sixes... He said they were certainly of thinner material than the fives,
but he had not heard of anyone reporting problems with bulging or unusual
softness in the lower sides like mine.
He asked me to put out a call on the List and see if anyone else had
observed a similar problem with the six gallon tanks...
Any takers...??
