Aviation Fuels
It is possible but not recommended to use 100LL AVGAS, since the the lead content
is like cholesterol to your engine: it will accelerate wear on the valve seats,
create deposits in the combustion chamber and sediments in the lubrication
system and gearbox. Increased maintenance is necessary to compensate. Unlike
"conventional" aircraft engines, lead is absolutely not essential to the proper
lubrication and operation of a Rotax 4-stroke aircraft engine. The increased
octane rating also has no marked advantage for the operation of your engine.
To be avoided:
"Regular" fuel except if used in the 912 A/F/UL and burned entirely on the day
of purchase;
"Premium" fuel which is more than 3 weeks old
AVGAS except when the required automotive fuel is not available

I bought a Kitfox ASI from him last March. I think it was 55$ or so.
I have not installed it yet. Mine , like many reads high at cruise and low at
stall.
eg cruise TAS 93 ASI read about 110 mph
stall TAS 37 ASI reads about 25 to 28 mph
at approach 50 MPH it is dead on

Prior to my purchase...I built a manometer to check the pitot and static systems.
It will also check the accuracy of the gauge. The "new" Kitfox ASI and my
Rocky Mountain Encoder (digital) both read within 2-3 MPH through the entire
speed envelope. Also, they are both accurate (calibration) within same.

Travis, I do not have a external static port.
My ASI will lower about 5 mph when i open door at cruise
and it if drag my arm out door the more wind resitsance i get the lower the ASI
goes.
I should really build a external static port but it just never been an issue. I
could assume that if i install the new ASI that my readings would be just as
erratic ?

Without a static port (just open to the cockpit or back of the instrument) your
ASI can change as pressure inside the airplane is increased or decreased. When
you open the door (generally speaking) you are increasing the pressure inside
the cockpit which would cause a decrease in your ASI reading.
A friend our our "little" airport flys a Thundergull J2. He has it sealed up nicely
and installed numerous vents. During the cool season he didn't have a problem
on landing (speed wise). But come summertime he was landing long and hot.
Turned out that with his vents open, he was reading approximately 8-10 MPH
slow. One of his leg vents was also directing air towards the end of his static
tube outlet (behind the panel).
...stuff happens!
...Oh...about your arm stuck outside. You are probably directing more air into
the plane...more pressure...lower ASI reading.

YUP !!
But in all fairness, the ASI is fairly accurate "guide" to your airspeed just
the pilot knowing his airplane is even better. I think that most should learn
to fly without one in the case of your not working. Part of my pre flight is
to check the little flipper on my pitot tube as it seems to stick once in a while.
I just put on floats about 6 weeks ago and the first flight i forgot to check
it so i flew without the ASI for the first hour of flying to the lake and
back.

| Subject: | 91 octane, time to be heard! |
Run the regular unleaded unboxed gasoline... if you notice the engine
pinging then consider switching to a higher octane fuel. Generally speaking
the line for high octane requirement is with a compression ratio of
somewhere around 11:1.
I've been called on my dislike of ethanol as fuel in the past and I do tend
to use strong language in my opinions on the subject. Fact is no one has
been able to show me that ethanol is anywhere near as cost effective as oil.
No one has commented either way on the poisonous, ozone layer eating gasses
given off when organic oils, including ethanol and bio diesel, are burned.
One guy, a farmer I think or the holder of a mortgage on a farm, told me
they are now using ethanol to fuel diesel tractors.. Now I wonder how many
miles they get to the injection pump. There is no viscosity to ethanol so
what lubricates the pumps???
Ethanol is pretty corrosive stuff and makes a pretty good cleaner so I'm not
against using small quantities of it, occasionally, on the ground, to clean
out combustion chambers.... but IMHO that alcohol has no place in the air
except in business class.
As for seeing ethanol in your fuel in Alaska; I doubt you ever will see it
except by some accident. As I said the stuff is corrosive and no one who
owns a tanker ship really wants the crap in their hold with the possibility
of eating the ship out from under them. Of course they could build a
distillery in Alaska and ship raw corn or sugar there to make the ethanol on
site. What do you figure the chances of that are?? Another point is you
guys store your gas for months at a time... in above ground storage
facilities...I wonder what ethanol can possibly do to those facilities...
Hmmm

If it is a stock Soob, it ran just fine on regular 87 in the car and should
in the plane. Now if you raise the compression, that makes the difference
between using reg or 92-92,whatever. Correct me if I am wrong folks. Been

I did read somewhere about the development of an unleaded octane 92 aviation
fuel. It was called 92UL. Handled like all other aviation fuels without
the remixing of recipe auto gas has for seasonal changes. Sounds like the
right stuff. Most engines in service right now won't require any
modifications with the possible exception of hardening valves and seats and
we won't be pumping lead into the atmosphere. With the ridiculous cost of
producing ethanol taken out of the equation and the lack of road taxes the
92-UL gas should be a little less than MOGAS.

Hi Noel,
I think that's all anyone wants is some fuel we can use with no alcohol.
Many people like the unleaded 91 because it's cheaper and less damaging to
their engine than the leaded stuff.

Subject: Kitfox-List: Ethanol Myths - Facts and/or fiction?
First off I am not in favor of ethanol by any means. That being said I use
it as I have other choice. And I use over 1000 gallons annually in my Kitfox
alone.
Rather than posting the fears and or myths why not let compare notes on what
has in fact happened with continued use of ethanol gas. I will tell you that
I must be lucky if any of these myths are actaully fact.
Ethanol Gas is likely better for Rotax engines than is AVGAS but yet many
chose to run avgas. ?

Like i continue to say, I fly 200 to 300 Kitfox rotax hours per year and have had
NO ISSUES yet with ethanol gas......... so myth or not?
You guys keep telling your selves how bad it is and how many hours does anyone
else fly annually to make those myths actual reality?
I do not support ethanol fuel but I have little choice in the gas I purchase.

Stevie Wonder could'a caught that one, Deke!
A little update on the repair process....the word back from Jabiru
was not encouraging, and I'll leave it at that. (I want to first see
if it's ok to pass along what was said)
At this point, I've got the engine completely disassembled. I had
done a run-out check on the gear end of the crank, and found .0015"-.
002" run-out. This could have caused the gear to fail, or could have
been caused by the gear teeth being wedged between the crank, the
remains of the gear, and the gear housing. Either way, run-out is run-
out, and the Jabiru engine manual doesn't give the accepted amount of
run-out. I'll have to consult with them on this measurement. Most
other measurements are within specs, with the exception of the valves/
valve guides. I'll have a valve job done, or if I don't get a "warm
fuzzy" feeling from what I perceive,(that is, do they do it, or send
it out to their local automotive guy) I'll get the parts and do it
myself or have it done by the local aircraft engine rebuilder, if he
would even take it on. This guy is a good friend of my flight
instructor, so we'll see what gives when that time rolls around.
There is always the possibility that I can get a factory rebuild, if
it turns out that this crank is out of specs due to the run-out
issue. The crank in all other aspects is perfect....no wear, bearings
and crank bearing surfaces are primo, and it looks like it would
easily go the rest of the 1500 hrs to the 2000 hr overhaul time.

Hi, Noel.
In fact ethanol itself is as corrosive as water. And water is the main
problem with ethanol cause it absorbs it from the air moisture.
Ethanol is not delivered in 100%. It's allways hidrated. And it reacts
sometimes with gasoline, resulting in an aldheyd.
You're right when you tell us to avoid its use on a system built for gas.
But, as I have said before, we have, in my country, lots and lots of
certified planes ( Cherokees, Skylanes, Bonanzas...) running on just
hidrated ethanol, and flying fine and safely for many years. It's necessary
to say that the hole project is intended to the use of alchool, not only the
engine.
I strongly recommend that you all DO NOT use ethanol added fuel in your
birds, unless all parts, including the engine , are certified for this
particular use.
But we're living the third large oil market shock in history, and history
teaches us that something has to be done 'cause fossil fuels will end
someday.
I'm sure our sons or grandsons will be flying on some bio-fuel, and the
technology, in their days, will be as fine for the bios as they are for the
oil derivates today.
And, while waiting, let's fly just on factory parts recommend fuel and
contamination limits.
I own a Continental engine, and cannot even think about any ethanol.
As I'm looking for an experimental plane and Rotax or Jabiru will be the
engine choice, I'm as interested as you all in this subject. So I argued
Rotax factory on this subject and I'm waiting for the answer.
And that's why I'm in this list. To share experiences.
I've been fueling my cars with ethanol or ethanol added gas for decades.
Believe-me, it's not for our planes the way they are powered and equiped.

Assunto: RE: Kitfox-List: 91 octane, time to be heard!
Run the regular unleaded unboxed gasoline... if you notice the engine
pinging then consider switching to a higher octane fuel. Generally speaking
the line for high octane requirement is with a compression ratio of
somewhere around 11:1.
I've been called on my dislike of ethanol as fuel in the past and I do tend
to use strong language in my opinions on the subject. Fact is no one has
been able to show me that ethanol is anywhere near as cost effective as oil.
No one has commented either way on the poisonous, ozone layer eating gasses
given off when organic oils, including ethanol and bio diesel, are burned.
One guy, a farmer I think or the holder of a mortgage on a farm, told me
they are now using ethanol to fuel diesel tractors.. Now I wonder how many
miles they get to the injection pump. There is no viscosity to ethanol so
what lubricates the pumps???
Ethanol is pretty corrosive stuff and makes a pretty good cleaner so I'm not
against using small quantities of it, occasionally, on the ground, to clean
out combustion chambers.... but IMHO that alcohol has no place in the air
except in business class.
As for seeing ethanol in your fuel in Alaska; I doubt you ever will see it
except by some accident. As I said the stuff is corrosive and no one who
owns a tanker ship really wants the crap in their hold with the possibility
of eating the ship out from under them. Of course they could build a
distillery in Alaska and ship raw corn or sugar there to make the ethanol on
site. What do you figure the chances of that are?? Another point is you
guys store your gas for months at a time... in above ground storage
facilities...I wonder what ethanol can possibly do to those facilities...
Hmmm

If it is a stock Soob, it ran just fine on regular 87 in the car and should
in the plane. Now if you raise the compression, that makes the difference
between using reg or 92-92,whatever. Correct me if I am wrong folks. Been
there before. Larry

My understanding is a bit different=2C the AnP is only required for the yea
rly conditional inspection. I believe anyone can do anything with an exper
imental aircraft but a major change like an engine or prop change must be r
eported to the FAA and the plane has to go back into phase one flight test
for as long as the FAA says. Check the archives=2C this has come up before.
I have changed engines on both of my Avids=2C one required a FAA inspect
ion because it was under the old set of experimental rules=2C the other Avi
d had the newer type airworthyness cert. and no inspection was done=2C but
both planes had to go back into phase one for 10 or 15 hrs. It doesn't sou

I'm too lazy to dig out my paperwork, but my "experimental
certification" documentation described when the FAA needed to get
involved. (I think it was as Jim said, engine and prop.) All other
modifications, not repairs, required that the plane be placed back
into phase 1 flight testing for a minimum of 5 hours. The "builder",
(current owner,) gets to decide how long. Repairs do not require any
flight test. Hopefully you have your original paperwork. If the plane
has moved, you'll have to go to the nearest FSDO for a phase 1 flight
test area. The only reason you need an A&P for an experimental is to
sign off the yearly conditional inspection assuming you don't have
the repairman's certificate for that particular aircraft.
Finally, unless it's a major change and the FAA gets
involved the only ones who care whether you do the phase 1/2 thing
are your insurance company and the plaintiff's attorneys. Plenty of
people skip this step, but some who have had subsequent problems
staying aloft have found their insurance denied.

I am in the process of fitting the pants - the instructional drawings are
pretty poor and I don't quite understand the process re cutting the
inside of the pants for the gear legs. Do you just cut enough fibreglass
away to clear the obstructions (gear leg and brake lines etc) and then use
the aluminum covers to cover the opening with the bent lip at the bottom.
As you have the Grove gear this probably makes no sense at all so if
anybody else has the tube gear and wheel pants I'd love your comments.
For the record I am a mechanical engineer and these instructions have me
beat!

Interesting comments here re fretting of crank and timing gear for engines
with the smaller flywheel bolts and no dowels. Sounds as though even the
new recommended torque settings might be understated?
