Ted Time: 08:50:27 PM PST US From: "Don Gherardini" Subject: Re: Kolb-List: Firefly with H section --> Kolb-List message posted by: "Don Gherardini" Hey Gang.... I converted my FireFly to single lift struts...look at my website and on the bottom of the pages the button that says "strut mod" will take you there and show you how I did it... The method of attach that the stock Firefly uses to attach the strut to the spar is different than on a Firestar..I dont think it is weaker...just different. the Fly uses a large bracket that rivets to the spar...kinda makes a square box out of it where the struts attach and a steel attach bracket then rivets to the box section. The end of this attach bracket then sticks thru the fabric and each of the 4 struts attach to it with one bolt. The "T" section that I made simply uses the stock attach brackets and allows one to use a single strut. I sent pics and specs to to Dennis before I completed it and asked for any advice he might offer....he basically told me it looked like it should do the job fine. I gained 5 mph or so with this and the other mods to cover the top half of the rear cage and added a streamlined "ducktail " to the rear of the cage.

I burned a lot of 100LL aviation fuel in my Cuyuna and Rotax engines. Never had a problem with it. | if not - how do you all take a cross country trip? do you stop at local airports and run into town and get autofuel and fill up that way? I have heard of folks cross countrying ULs, using the FBO courtesy car to go to town to buy autofuel. Personally, I think that is in bad taste. Poor old FBO, at most little airports, is struggling to survive. Needs all the help he can get. Buy his 100LL and help him out. Then borrow his courtesy car to go to town to get a hamburger. Be sure to put some autofuel in the courtesy car before you return it. | I"m told mixing the 2 cycle oil right in with the gas is best since if you instead have an auto injector - if the auto injector fails - you fry your motor? Is it seldom that these auto injectors fail??? Either way works great. I don't think the injectors fail any more often than the operator fails to add oil in the fuel. | The Ultralight I purchased is in Virginia - i'm thinking of flying it to Sun'N Fun - is that a HUGE trip - I figure 15 hours? That depends on your past aviation experience. I started cross country flying in my Ultrastar 20 years ago. All one day flights. When I built the Firestar I had more room to carry camping gear. To determine what I would need or not need on a cross country flight, I did a one day flight to an air show, camped out on site, and returned home the next day. This gave me a good idea if I had what I needed. Am I bitting off a bit more than I should for a first trip in an Ultralight? Probably! Recommend getting out there and doing a lot of cross country work with some overnighters to get yourself and your ultralight in shape for the flight to Lakeland. All long and extremely long cross country flights are simply short individual flight legs put together, one at a time.

I asked the owner/operator of the Authorized Rotax Repair station who does my repair and rebuild word about avgas. He said it won't hurt your engine, especially if used on an occassional basis. He recommends always following a tankful (or tripful) of it with a good quality 93 octane. 2. How do I take cross-country trips? Three ways: First, I buy avgas, as mentioned above. Second, I -carry- gas in the second seat since I have a Mark II. Third, I fly to places that offer mogas or it's within easy ( and I mean real easy) walking distance. 3. Pre-mixed -vs- oil-injected. Again, referencing the gentlemen I mentioned in item 1, he tells me that the incidence of these oil-injector pumps failing is so low as to be hardly worth considering. Nevertheless, the pumps are -designed- to failsafe, that is, if the pump quits or the cable breaks, the flow reverts to a full 50:1 mixture. Ergo there's no chance of frying the engine UNLESS you run out of oil in the reservoir. You didn't mention what type of Kolb you purchased? -Ken Fackler Kolb Mark II / A722KWF Rochester MI ----- Original Message ----- From: "Clifford Dow" Subject: Kolb-List: AvGas & Rotax 503 > --> Kolb-List message posted by: Clifford Dow > > Hello > I'm new to Ultralights - can you run a Rotax 503 with regular avgas (mixed with 2 cycle oil of course)? > if not - how do you all take a cross country trip? do you stop at local airports and run into town and get autofuel and fill up that way? > I"m told mixing the 2 cycle oil right in with the gas is best since if you instead have an auto injector - if the auto injector fails - you fry your motor?

I recommend you find a BFI in your area and get some dual in an ultralight before you try to fly yours. This will make your first flight a pleasant experience and help insure your second.

Even with 250 hours time GA, the transition to U/L's will be VERY enlightening. The LONG cross-country you are thinking of is not an endeavor I'd recommend on your 1st effort to become acquianted with this medium. George Bass P. O.

I work for ChevronTexaco in a 350,000 BPD oil refinery on the Gulf Coast. We have two pipelines that leave our facility and pump into what is known as the Plantation Pipeline where it goes to Collins Ms. and then is distributed to a major pipeline network that goes up the east coast known as the Colonial pipeline. One of our pipelines is for gasoline and one is for mid-distillates (diesel and jet fuel) and I can assure you there is no sludge pumped into the pipeline or the tanks as the gas is being blended. The fuel is monitored very closely and samples are caught from the pipeline on a routine schedule even though the tank that is being used to pump up the pipeline has passed all product specifications. I can assure you that the gas that goes up our pipeline is clean because it still has to pass the same specifications when it gets to the other end. They all have to meet stringent government guidelines. The folks that maintain the pipeline and receive the fuel at Collins also test the gasoline and mid-distillates. Most, if not all of the producers and suppliers swap and trade gas with each other. An example is at our facility any trucks that load and are going to a Chevron branded station have Techron added to the gasoline as it's being loaded on a tank truck. We also have other additives to inject that go to other brand service stations. The additive that is added is controlled electronically with a computer system. The same thing happens with barges. We load all types of fuel on barges from our facility that are sold by the other major oil companies. The gasoline we pump up the pipeline or load on barges doesn't have any Techron or other additives in it. It is added at it's final destination depending on what company is selling it. Sorry for getting so long winded, but I wanted to be sure folks didn't get the wrong idea about your statement. do not archive John Cooley -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com]On Behalf Of WADE LAWICKI Subject: Kolb-List: re: av-gas --> Kolb-List message posted by: WADE LAWICKI it is my understanding that rotax does not recommend using anything other than 87 octane because, higher octane's =excessive heat. heard that at sun-n-fun last year from rotax service. i used to run Amoco premium now just regular but, still Amoco! i used to do work for a pipeline and Amoco is the only fuel that does not allow sludge to be added to their fuel to lube the pipeline. you would not believe the stuff they put in it. wade fs #1030 do not archive --------------------------------- ________________________________ Message 20 ____________________________________ Time: 09:42:29 PM PST US From: "Jim Baker" Subject: Re: Kolb-List: re: av-gas --> Kolb-List message posted by: "Jim Baker" > Higher octane does not necessarily mean higher BTU output. > -In fact alcohol added as an antiknock actually lowers the energy > output.

Qc, heat of combustion in BTU per pound mass (lbm) Gasoline C8H17 20,460 Methyl Alcohol CH3OH 9,760 Ethyl Alcohol C2H5OH 12,780 Alcohol was never intended to be an anti-knock agent, it was just a consequence of economic and political pressures. At 10 percent ethyl alcohol by volume, antiknock effects are minimal. You'd have to get to 50 percent alcohol by volume before you'd equal the effect that 3cc/gal of tetraethyl lead (TEL) has on the same volume (Taylor, Vol 2., The Internal Combustion Engine in Theory and Practice, pg 152). 100ll currently has, if I recall, about 2cc/gal TEL. The BTU/lbm of gasoline is the same for auto or aviation fuels. There is no great difference. From another post... >avgas. He said it won't hurt your >engine, especially if used on an occassional basis. He recommends always >following a tankful (or tripful) of it with a good quality 93 octane Why use the 93?
