Your improvements look great but I cannot help but think that you have increased
the weight of this bird beyond FAR 103 and the speed also probably. I realize
you are having fun modifying this bird but I would think you had better be
getting your registration for N number. Ted

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.
Here is a direct link to the strut mod page

--> Kolb-List message posted by: Clifford Dow <cdowjr@yahoo.com>
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?
Is it seldom that these auto injectors fail???
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? Am I bitting off a bit more than
I should for a first trip in an Ultralight?
thanks

Hi Cliff/Gang:
I've only had one cup of coffee and working on the second, but I will
see if I can answer your questions.
| I'm new to Ultralights - can you run a Rotax 503 with regular avgas
(mixed with 2 cycle oil of course)?
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.
Take care,
john h

Clifford:
I can't advise you, nor can anyone else, on whether or not you should fly to
Sun-n-Fun, but I can offer some experiential advice on your other questions.
1. 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?

Hi Cliff/All:
What is your aviation background/experience?
Like I said in an earlier post, "long cross country flights are not
"huge". They are simply a lot of short flight legs tied together."
If you do not feel comfortable flying long cross country flights by
yourself, might be a good idea to get out and start flying some short
cross country flights, get some competent instruction, and some
confidence.
Take care,

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.

Hi Cliff / all
Ultralights are wonderful little airplanes to fly and loads of fun
but fly nothing like a 150. 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.
Keep us posted and let us know what kind of bird you have.

The key phrase in Mr. Dow's last comment
was ZERO TIME IN ULTRALIGHTS.
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.

Higher octane does not necessarily mean higher BTU output.

I know it is silly but we had a pilot with the same trouble. His air
filter was saturated with oil. Also check your flexible hose from your
carb to your engine. It gets cracks in it and will act up like you said.
I had a Kolb 503, double carb. I crashed it at the NY Fly-in because of a
faulty throttle linkage.

Wade and Gang,
I normally don't respond to post that I may think are untrue but in this
case I can't bite my tongue and be quite since you stated that "Amoco is the
only fuel that does not allow sludge to be added to their fuel". 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.

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...

Why use the 93? Betcha he couldn't tell you, either.
