I'm glad to see that somebody else thought that $3600 for experimental skis is
nuts. And they aren't even painted. Seems to me that either their manufacturing
process is too expensive or they are trying to get a premium profit just because
it's aviation.
I'd be willing to pay $1500 max for a new set of LIGHTER, wheel penetrating skis
that have had some market exposure and positive feedback. (I prefer John's
suggestion of 500 bucks)
I don't know if I should wish these aviation entrepreneurs good luck or be mad
because they are trying to make the aviation lifestyle that much more expensive
for us regular Joes.

Funny you should mention lighter, wheel-penetrating skis...I'm in the
process of ordering/building a set right now, based on the best ideas
that I've heard/seen/read about. I'm certainly not in any position to
market anything....just building a set for my own pleasure, if the
snow ever comes this way. Maybe I should be glad there's no snow
yet...might be tempted to clamp on some barrel staves, and give it a
go. : )
There are others out there that might be better suited to build/
market a set, and maybe your comments will stir some
activity....anyone...John, Dave, Michel?

This is standard procedure for a short field takeoff. I have used this
procedure for years in a Cessena 180 and now in my Speedster.
I havren't measured the distance with a tape measure but I am sure that
less than 100 ft is entirely possible.

Less than 100 feet? calm day? Wow awesome
I thought I could TO short :-)
I once had a bit of snow on my runway so I could plainly see and
accurately measure I also tried different things. Best I got was a bit
under 200 feet on a cold day, no wind, solo, 1/2 fuel. Most were around
225 feet.
I even have some on vid
Full Brake full power full up elevator, release brake, after about a
long second, full down to level. Adjust elevator to maintain level, then
as I pass 35 mph Up to rotate.
My strip is 750 feet total. So I practice this all the time.
I cant imagine a KF taking off in less than 100 feet, that has to be a
rush!

yes 3600 out of my pocket book for a Kitfox.
There are some manufactures that make them for about 1500 for challengers
but a Kitfox is a bit heavier and those are straight skis. I think 1000 $
would be a very fair price for a pair of 4130 wheel skis. I have straight
skis now and when I get my 21 iuch tires from Jim, perhaps i should make a
set that would accommadate others? I have 16 inch golf cart style tires now
so I do not think that that would e a common size tire/ski combo?

I was just out this am , My IV weight is about 540 plus my fat ass of
215 and 6 gals fuel .
temp 34F wind 3 knots at 210 and i took off on heading 170 and was
off in about 120 feet or less across a 100 foot wide runway-- and it
all grass ,unfrozen ground. And thats was zero flap till 30 mph then
full 30 deg + flap and rotate at once --pop up she goes.
Would be fun to try on a 20 knot wind day :)
I will mark it out one day and/or park some plane wing tip to wingtip
so it gives a good referance.
My 582 only getting 5900 static and I should re adjust to 6200 or 6400
rpm to get a bi better but it works pretty well all around now and with
colder temps coming it will elevate my egts then .

I have the straight skis but would prefer to have the penetration skis.
Loading the plane on a trailer is easier with the wheels, not to mention
putting it back in the garage.
May be the way to go would be for someone to offer a ski kit. That would
remove all liability and could lower the prices. The kit should include
Axels drilled etc to accept the ski mount, the ski frames and a ski skin
along with cables, bungees and the cable fittings. Done that way I could
see the cost drop close to the $500 mark.

| Subject: | Re: More speeds: Older Kitfox cruise speeds |
I have experimented with full flap take offs, and what I found was an amazing takeoff.
I did mine where I was full flaps and was rolling a little, hit the throttle
and away I went. It was amazing how the tail sprang up off the runway,
and the lift wow. The only thing was I left the full flaps on at altitude and
quickly found a huge drag and of course the turning was junk. I sense have
found that you remove the flaps as soon as you can to gain airspeed and control.
Another thing to watch out for is the tail comes way up and a prop strike
is possible. I have a 68 inch powerfin 3 blade so I have extra room to play
with, but if you have a 72 inch, I feel you could be in trouble. I limit myself
to half flaps, but most all take offs are no flaps and I can still get off
within about 200ft. plenty for me.

Noel,
NO chance of 500 $ unless you talking EACH !!
4130 is 3 to 5 $ a foot alone.
you will need 20 to 25 feet per ski
UHMW is about 3 to 4 $ a square foot.
10 sq feet needed.
Am I missing somthing ?
Also ........ A tip to move in shot on skis ..... use a 2 x 6 that fits
under the axles and between the calipers and put on a floor jack . lift up
a few inches and pull the plane on floor jack . If you have a tail ski it
will drag ok or put a dolly under the tail ski.

Gentlemen,
Currently I have less than 30% of our customers current e-mail addresses.
I am attempting to update our mailing lists to see if they have any questions
re their RiteAngle IIIb Angle of Attack systems. Occasionally I get a call
from someone who purchased a system several years ago and still do not have
system installed or set-up due to various reasons.
Should you have any questions, comments, photos of system installed in your
plane, endorsements or whatever re: the RiteAngle IIIb system please send it
to this address _riteangle3@aol.com_ (mailto:riteangle3@aol.com)
Thankfully, since the IIIb system has gone into production, we have had no changes
in
the electronics, however we now have a professional written setup manual.
Sincerely

Those were my skis Dave that I made for my M2. They were fine (and very
effective) for that airplane at just over 500 lbs and would be OK for up
through the IV if kept light, but wouldn't be enough surface area for the
heavier models like the 5+. Interesting enough, the total weight of each
ski was less than the wheel and tire. Axle bushings were just hardware
store bronze units at a couple bucks each. The ABS plastic skis provided a
very slippery surface and takeoff was about the same as the wheels. I even
used them on bare concrete a few times with very little scuffing.
Unfortunately, when I sold the II, the skis went with it. Fairly easy to
make though. If anyone has any questions about them just let me know.

| Subject: | Re: less than 100 foot take off ... cool |
Dave,
Back in the late 80's and early 90's it seemed everyone with an Avid
Flyer or a Kitfox was trying to outdo the other guy in the short takeoff
category (other airplanes generally can't even compete with our
airplanes). So to defend the STOL KING credentials of my Avid Flyer, I
practiced, practiced, and practiced some more my short takeoff
technique.
I found what worked best is to hold brakes with full power until you
feel the airplane starting to overcome the brakes (we had poor
mechanical brakes way back when, so that was almost immediately), then
within a few feet of the starting roll to release slight stick back
pressure, just enough to let the tailwheel rise ever so slightly (a
couple inches off the surface). Then just before you thought it might
fly (in my airplane at the time this was just as the airspeed indicator
was coming up on 20 mph), jerk the flaps on full while burying the stick
in your lap. This would normally provide a "main gear first" liftoff,
followed by the tailwheel. Of course as soon as you were off you had to
reduce the back pressure as well as about 1/2 the flaps. But you were
off very short, and in those early planes climbing out at about a 45
degree angle!
The thought process behind using this technique is;
1 - The drag caused by rolling down the runway with the wing at a high
angle of attack is minimal at best when you consider the very slow
speeds a light Avid or Kitfox can lift off at (20-25 mph), and the short
distance you rolled (50-75 feet) .
2 - With the high wing angle of attack right from the start of the roll
the very high lift airfoil (especially of the early airplanes) goes to
work lightening the aircraft, allowing it to fly sooner. If nothing
else, it forces the lift off at the least amount of speed needed, rather
than relying on the pilots judgement of the rotation time or speed.
3 - By releasing just enough back pressure to let the tailwheel skim a
few inches off the ground, you've minimized wheel drag for one of the
wheels, but yet maintained that high angle of attack of the wing for the
most lift.
4 - When you really knew your airplane and were able to pull back on the
stick and the flap handle at just the right moment, you caused a
"ballooning effect" much like when you first apply flaps on a decent.
That balloon effect on takeoff maximizes use of ground effect.
Why not raise the tail and rotate? Well, on the early airplanes the
takeoff was so quick that seemed like nothing more than a waste of time
to me. Plus I was busy enough the way it was. So does this technique
still apply? I think so. I'm sure someone will tell me why it won't
according to some other source, but I still use it. A similar technique
gets my 775 lb 912ul amphib Model 4 off the water in 8 seconds (although
in that case I also raise one fly by applying full left aileron and a
touch of left rudder while jerking on the stick and the flaps...).
That is a very short takeoff for an amphib, especially one with only 80
horsepower that has everything but the kitchen sink on it.
Unfortunately I can't tell you how it compares on wheels as I haven't
yet flown my fox on wheels. But I'm sure it will do a 4-5 second
takeoff on land (even without doing the math, I'm sure thats not a lot
of forward distance).
Here's a little story describing just how well my practiced technique
worked; I once won $100 in a bet against a guy that owned a souped up
360 hp IO-550 powered 185 Cessna by having a group of other pilots
measure off my Avid Flyers takeoff. He said there was no way I could
take off in a hundred feet (the claim I made to the group that he
overheard) and went on to make jokes about my snowmobilie motor powered
toy airplane. Of course I had to defend the Avid, so I bet him $100 I
could do it in less than a hundred feet, and certainly shorter than he
could with his hot rod Cessna. Oh yeah, we had a density altitude at
the time of almost 4,000 feet as it was 90+ degrees out (with

airport measure for me, as I took off sideways on a taxiway (the airport
manager knew me and my plane well, so went along with my little
escapade). 52 feet was all I used that day. Being verified by a bunch
of other pilots (some his buddies even) as well as himself, made him eat
a lot of crow that day. And he wasn't interested in showing us how
short he could take off in his big buck hotrod Cessna either. To
conclude this story, for the record I never took his money. I just told
him to be more careful in the future about picking on guys with
homebuilts. Especially those with two stroke engines. He still talks
to me today, and occasionally teases about one day owning an Avid Flyer
or Kitfox.
And for further proof we can get our airplanes off short, just check out
what John Knapp does at Oshkosh or Greenville with his two stroke
powered Avid Flyer on floats. He holds the world record off the water,
2.7 seconds!!!! I have some video that one of these days I will load of
John doing some of his takeoffs. In one, I don't think he uses more
than 6 feet! Yeah, I did say SIX FEET.
Play around with your takeoff techniques. These airplanes are all
pretty amazing performers in the right hands (eg. Jimmy Franklin, John
Knapp....) No reason you can't become that expert like with your own.
And when onlookers see how well our airplanes perform, John McBean just
might sell a couple more Foxes.... the more the merrier.
Happy New Year!

oh yeah, the Avid I was flying back then was an A-model (similar to the
model I kitfox), powered by a 532 Rotax. However, the airplane only
weighed 396 pounds, and that little ol' 532 dyno'd bone stock at 73
horsepower. It was a real performer, like most of the earliest

Less than 100 feet? calm day? Wow awesome
I thought I could TO short :-)
I once had a bit of snow on my runway so I could plainly see and
accurately measure I also tried different things. Best I got was a bit
under 200 feet on a cold day, no wind, solo, 1/2 fuel. Most were around
225 feet.
I even have some on vid
Full Brake full power full up elevator, release brake, after about a
long second, full down to level. Adjust elevator to maintain level, then
as I pass 35 mph Up to rotate.
My strip is 750 feet total. So I practice this all the time.
I cant imagine a KF taking off in less than 100 feet, that has to be a
rush!

Sounds way cool. I do some pretty short take off and landings. In fact when I
get in the grove for short, inside, approaches. I commonly hear other pilots
asking what kind of aircraft I'm flying. My favorate is to do 3 touch and goes
on the 172's while there on their final. On my take off's, I like to get off
the ground as soon as possible, run within 10feet of the ground and get my
speed way up then pull up and do a turn, real fun, and, gets a lot of lookers.

Interesting reading, Paul. Of course, I won't tell you why one should
raise the tail and rotate, I know much too little about aviation, I am
merely reading and learning. Reading your email definitively tells me
that I should try other take-off techniques than the one I use. The key
element is probably that when I tried to take off with a high angle of
attack, I didn't had enough speed and was pulling too much the stick.
If you have ever done that, you know that it doesn't feel right and you
hope nobody is watching.
I think I'll have to try until I find the correct stick pressure.
That's the nice thing about flying: Always something new to try, always
something new to learn, always a good reason to go out flying ... Now,
if someone can tell that to my wife! :-)
Happy New Year,

Just a second, Lynn, I'll take a crash course in welding then I'll make
you a nice pair of skis ... kidding! :-)
Just an idea: I think wheel penetration skis don't have to be very
strong. If they are, and you hit a rock hidden under the snow, they
might bend your gears. If the are not, you'll bend the skis but your
wheel will still be there and that what's matter, isn't it? You can
then remove the skis and fix them while the plane is ready to fly for
the summer. Just a thought.
Cheers,
Michel

Michel,
I just in from 2.5 hours flying today in total.
I mentioned that i was doing airstarts after gliding the Kitfox and I
thought about you today so I went up and shut off mags and slowed to about
40 ias till the prop stopped. Then came this bright idea *** oh yeah
BRIGHT !!
well why not do some stalls and take off the headset to hear the sounds you
described before and all i heard was the air leaks !! I did about half
dozen stalls -- all power off and mags too !! some steeper than others
and I just get a shudder and a mush for the most part. Now once you put
nose down just after you break the stall I do get a bit of a THUD from the
rear........ I am guessing it the disturbed air on top of wing washing onto
the tail ?
Maybe if I hear air leaks then i have some taping and sealing to do some
time ?
Hope that helps you and it was fun........

| Subject: | PAUL : less than 100 foot take off ... cool |
Paul, Thanks for that post.
I did at least a dozen takeoffs today all definably 120 feet at the
longest.
I did try different flap settings and tail up tail down tail light on
tailwheel etc..........
Conclusion ? Well 20 degrees stick neutral wide open throttle let go of
brakes and it will fly off in 120 or less feet.
This is probably the best soft/short field combo for all round use.
I maintain that getting tail up so your AOA is zero and pull full flaps
( over 30 degrees is necessary to achieve best results) and at the same
time you yank that flap handle FULL you yank the stick back full and if
you not ready the tailwheel smacks the ground and if you ready the wings
and tail are flying and the tailwheel will not smack the ground.
What would you think of a longer landing gear ? say 3 to 5 inches longer
extended from what I presently have ?
I am not sure if that would be worth it or not.
I will tell you that the guy who is doing those tests on the Zenith 701
without the Slats runs a company called www.stolspeed.com and he sells
VGs called Feather Vgs . He sent me some to try after seeing my last 3
videos I posted. ( he might be on this list , I am not sure) .
Anyways I will report the findings when I do in fact try them to anyone
interested. I did tell him that I have a good flying Kitfox now and I
did not think that the VGs will do much good for me but he sent them any
ways as he liked my videos. If they work well you will know and if
they don't well you will know as well. Am I told him that 701s have
similar performance to a Kitfox in the STOL part but they just plain
Ugly and slower. ( VERY Big Grin )

Dave,
Back in the late 80's and early 90's it seemed everyone with an Avid
Flyer or a Kitfox was trying to outdo the other guy in the short takeoff
category (other airplanes generally can't even compete with our
airplanes). So to defend the STOL KING credentials of my Avid Flyer, I
practiced, practiced, and practiced some more my short takeoff
technique.
I found what worked best is to hold brakes with full power until you
feel the airplane starting to overcome the brakes (we had poor
mechanical brakes way back when, so that was almost immediately), then
within a few feet of the starting roll to release slight stick back
pressure, just enough to let the tailwheel rise ever so slightly (a
couple inches off the surface). Then just before you thought it might
fly (in my airplane at the time this was just as the airspeed indicator
was coming up on 20 mph), jerk the flaps on full while burying the stick
in your lap. This would normally provide a "main gear first" liftoff,
followed by the tailwheel. Of course as soon as you were off you had to
reduce the back pressure as well as about 1/2 the flaps. But you were
off very short, and in those early planes climbing out at about a 45
degree angle!
The thought process behind using this technique is;
1 - The drag caused by rolling down the runway with the wing at a high
angle of attack is minimal at best when you consider the very slow
speeds a light Avid or Kitfox can lift off at (20-25 mph), and the short
distance you rolled (50-75 feet) .
2 - With the high wing angle of attack right from the start of the
roll the very high lift airfoil (especially of the early airplanes) goes
to work lightening the aircraft, allowing it to fly sooner. If nothing
else, it forces the lift off at the least amount of speed needed, rather
than relying on the pilots judgement of the rotation time or speed.
3 - By releasing just enough back pressure to let the tailwheel skim a
few inches off the ground, you've minimized wheel drag for one of the
wheels, but yet maintained that high angle of attack of the wing for the
most lift.
4 - When you really knew your airplane and were able to pull back on
the stick and the flap handle at just the right moment, you caused a
"ballooning effect" much like when you first apply flaps on a decent.
That balloon effect on takeoff maximizes use of ground effect.
Why not raise the tail and rotate? Well, on the early airplanes the
takeoff was so quick that seemed like nothing more than a waste of time
to me. Plus I was busy enough the way it was. So does this technique
still apply? I think so. I'm sure someone will tell me why it won't
according to some other source, but I still use it. A similar technique
gets my 775 lb 912ul amphib Model 4 off the water in 8 seconds (although
in that case I also raise one fly by applying full left aileron and a
touch of left rudder while jerking on the stick and the flaps...).
That is a very short takeoff for an amphib, especially one with only 80
horsepower that has everything but the kitchen sink on it.
Unfortunately I can't tell you how it compares on wheels as I haven't
yet flown my fox on wheels. But I'm sure it will do a 4-5 second
takeoff on land (even without doing the math, I'm sure thats not a lot
of forward distance).
Here's a little story describing just how well my practiced technique
worked; I once won $100 in a bet against a guy that owned a souped up
360 hp IO-550 powered 185 Cessna by having a group of other pilots
measure off my Avid Flyers takeoff. He said there was no way I could
take off in a hundred feet (the claim I made to the group that he
overheard) and went on to make jokes about my snowmobilie motor powered
toy airplane. Of course I had to defend the Avid, so I bet him $100 I
could do it in less than a hundred feet, and certainly shorter than he
could with his hot rod Cessna. Oh yeah, we had a density altitude at
the time of almost 4,000 feet as it was 90+ degrees out (with
essentially no wind). So the group of other pilots hanging around the
airport measure for me, as I took off sideways on a taxiway (the airport
manager knew me and my plane well, so went along with my little
escapade). 52 feet was all I used that day. Being verified by a bunch
of other pilots (some his buddies even) as well as himself, made him eat
a lot of crow that day. And he wasn't interested in showing us how

Regarding these tires. I don't recall when I put them on my airplane, but
found some pictures John McBean took at the Cameron Park fly-in of 2003 and
it looks like they were on the airplane then.
I have 360 hours on the airplane since that fly-in and at least that many
landings as I have averaged at least one landing per hour. Most landings
have been on pavement with some really rough stuff in the Idaho trips. I
keep them at 10 psi.
So far no flats and no cords showing. That is what I will use to determind
thier service life. I have a replacement set, otherwise I would be an

| Subject: | Possible overheating and EGT question |
I discovered a small puddle of coolant under my airplane this morning. I had spent
the previous day practicing in the pattern for almost two hours and Im wondering
if the constant "touch & go" with all that time at full throttle caused
it to overheat. I'm ashamed to say that I did not notice if any of the gauges
where indicating anything out of the ordinary.
I ran her up on the ground for a while and could not reproduce the leak so I tried
a few turns around the pattern keeping a close eye on the gauges. As usual
the EGT runs near the upper range of the gauge during takeoff at 1600F. I didn't
used to worry about that because it's still just shy of max and it always
cools off once I level out for cruise. Today though, I noticed that it stayed
up at 1600 on the downwind leg coming down only when I pulled back to idle before
the base turn.
Is this normal behavior for EGT? Should I bump the mixture a bit? If I do adjust
the mixture, how do I keep the two carbs in sync?

I was actually referring to your friend...Paul?...who welded your

from one side to the other...was that a part of the 'not too strong'
school of thought? I'm not being picky, just observing.
I also just noticed your use of the phrase: crash course in
welding...hmmmm...interesting. : )
By the way, there is a guy over here in Michigan who is a flight
instructor and serves some other aviation job, and his last name is
Krashen...wonder how many folks walk away after being introduced to
him as their flight instructor?

p. s. I ordered the tubing for my skis yesterday. I've got a little
extra ordered to do some practice welding...gas and MIG...and to do
some practice bending. I like the bends that appear on the outside of
your skis, at the pivot point...keeps the leverage nice and short.

Torgier , Thanks !
funny thing is that the camera man flies Beaver Ultralight RX 550 with
full lotus floats.
If i ever let him take a kitfox out I am sure he would orphan the Beaver
quickly.
I have flown his beaver and I will be polite in saying that is was no joy
and if all Beavers are like that one they are close to the biggest pos I
ever flown. MAybe it rigged wrong ? Or I am just spoiled by flying a easy
handling Kitfox ?
One thing I could never understand is why Beavers, Chinnoks and Challengars
are so damn popular.
As Far as I am concerned , McBean should sell alot of Kits. And if a Kitfox
dealer was to have the three above planes on hand and take each customer up
for a flight in each plane , then without a doubt the Kitfox would make
their decision be made very quickly.

Duh. Sorry 912UL.
Is it typical for EGT to hit max at full throttle? Water and oil temps are nominal
as is oil pressure. Another thing worries me is that this Westach combo gauge
only goes up to 1600F. It looks like the needle is free to move beyond 1600
but there's no way to be sure.

Glad to hear that Lowell! My two sets arrived today and I must say I'm
impressed. If these were "yellow tagged" they would cost a fortune. How
much speed did you lose changing to the bigger tires. Since the Kitfox has
the speed wing I may try to put them on my stol Avid first. Hafta lose the
nosewheel first or it just wouldn't look right.

Dave:
The floor jack is a good idea for getting in and out of the shop but
wouldn't help me get it on the trailer. I have been considering bulling a
bit of snow up with my J5 and pulling the plane directly onto the trailer.
The WX here is a bit colder here today but we are a good ways off seeing the
bay freeze over. I'm not planning on taking the floats off until it is well
and truly frozen... We are only about 12 WK away from spring break-up.....
Of course in this part of the world spring break-up occurs when the ice
breakers come in to open the bay for lobster fishing. Late march... Fresh
water may not open until mid April.
The last few years have been pretty poor for ski flying... Less snow and no
sea ice. Inland you can land just about any where. There are laws that
don't permit the building of roads close to ponds so getting the plane off a
trailer in location that is usable for flying can be fun. The last owner
used to tow the plane behind his snowmobile about a half a mile to a frozen
bog he used as a strip.

| Subject: | Re: Possible overheating and EGT question |
Hi Luis, (not sure about your name)
Funny this thing, as I thought I'll write some- about the EGT system
before the New Year. Hmmm...
The thing is that, the EGT system is measuring differential temperature.
Ok., the system that is used for measuring the exhaust gas temperature is
measuring temperature difference, NOT absolute temperature!!
Well, it is measuring the temperature difference between the
cockpit(inside cockpit temperature -NOT the OAT!) and the EGT probe
temperature.
But you'll know, the temperature in the cockpit may change -then your EGT
reading change too!!!
To know your correct EGT temperature (at the probe) it important to know
the cockpit temperature.
So now, I'm wondering :) how many of you are using a true cockpit
thermometer?
Some of you might have the double temperature meter, that measure the
inside and outside temperature (with ice warning) for cars?
This is indeed a good idea (if you checked that the readings are correct)
as this can be used to calculate your "true" EGT.
The ting is that, your EGT system is calibrated at a known temperature!
Do you know this temperature for your instrument???
Now, think about this "calibration temperature" as a line across a
standard mercury meter scale, if your cockpit temperature is above this
line -your meter is reading to low!
This is because the meter (and the calibration point) is moving towards
the EGT probe temperature, see less difference I.E. reading to low.
The other way around, no cockpit heater (or a poor heater), I'm trying to
say that the cockpit temperature is below the "calibration value". In
this case, the indicated value will show to high, so we think that we are
boosting the red line. But indeed we should subtract the "absolute" value
of the reading BELOW the "calibration value" line.
In this latter case, our reading will be to high.
Ok., to summarize; in the winter time our reading will be to high, -and in
the summer time our reading will be to low, IF OUR COCKPIT TEMPERATURE
DIFFER/VARY WITH SEASONS FROM THE INSTRUMENTS CALIBRATION TEMPERATURE.
If you have a temperature controlled de luxe heater that can maintain,
say 23 deg. Celsius in the cockpit -everything become so much more
simple. :) :)
(I'll add a little bit more about this later.)
Now to your engine:
Doing touch and go is without doubt a real hard work for your engine, esp.
in the winter time.
As the temperature is going a lot down, and maybe it's CAVOK(a high
pressure), in this situ. your engine got lot's of more O2 -meaning better
combustion and higher temperature. Yes, we've to enrich to keep the
temperature in the green (one notch up and..). So this is why we have
more power during the winter season. (Sure that's more to say here..).
Also, as the air molecules is closer together we would have a better lift
as well. (Hey, winter flying is more fun!!)
In the winter time, cooling is also allot better, so this will normally
not occur, unless there is another problem. (If not, check your
thermostat.)
A last word, after such a hard work for your engine it is a good practice
to let the engine idle for some time to take the heath out. If not, we
often see that the engine start boiling after shut down. (Hint; this is
always a must for a turbo engine).
Torgeir.

What I have is the 6 and the 13.5 with a header of 2 Gal. ( all U.S.) I've
had flights of 3 hr with a good half hr. of reserve but at the low speeds of
these planes that's not a lot of range. I generally carry another 12 gal in
the right float if I'm going any distance. 3 Gal U.S. Jerry cans are great
for that.

Hi again,
Just a little important note.
When I said one notch up, I meant one notch to bring the needle up having
more rich mixture.
To actually do this, the locking ring has to go one notch down on the
needle itself...
Sorry, but do not want any confusion here.
Torgeir.

OK. Now I'm really confused. You wouldn't happen to know where I can find an illustration
of what you are talking about? Also, when adjusting the mixture at
the carb, how does one ensure that the two carbs stay in sync?

Luis,
Did you get my earlier response (off line)?
Changing the needle positions on the carbs does not have any affect
on the carb syncronization. Check out either the Rotax parts catalog or
the overhaul manual. Both show the needle and clip relationship in diagr
ams.
