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, 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 , 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. -Dana -- We're bored, We're heavily armed, We're off our medication, Is the post office still hiring? ________________________________ Message 3 _____________________________________ Time: 05:16:00 AM PST US From: "pj.ladd" Subject: Re: Kolb-List: Re: Pictures !!! Flying a Kolb Around South Arizona... aircraft sit outdoors at the mercy of rain,>> 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.

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?

I've never seen it published, nor have I tried to measure it, but like most ultralights it should be pretty slow. -Dana -- When authorities warn you of the sinfulness of sex, there is an important lesson to be learned.

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. Gary Siegrist Mark IIIc _____ From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of beauford T Sent: Wednesday, October 29, 2008 2:29 PM 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...?? beauford FF076 Brandon, FL ________________________________ Message 10 ____________________________________ Time: 07:34:54 PM PST US Subject: Kolb-List: Re: In Flight Video From: "Jim ODay" Wow!
