Don:
Although the model 2 has a smaller rudder, it has plenty of control for strong
cross wind landings. The adverse yaw created by the non-differential flaperons
is easily handled with the rudder. You soon find out the right amount of rudder.
The wings on model IV and above are faster. The wings in model III and
below are slower, but allow shorter takeoffs and landings. The main tradeoff
is the lower gross weight of 950 pounds. At 520 pounds and a Rotax 582, it had
excellent climb, and a cruise of about 65 mph with doors open. Expect to be
able to provide numbers for the Jabiru 2200 in about two months.

The Model I, II, and III Kitfoxes use the original Avid airfoil,
which is cambered on the bottom for maximum lift. The Model IV and
Series 5, 6, and 7 'foxes use a newer airfoil designed by Harry
Riblet that is convex on the bottom for better cruise performance.

The Model I, II, and III and early IV 'foxes have a noticeable
adverse yaw when the flaperons are deflected. The Model IV-1200 and
later 'foxes have a vertical stabilizer and rudder that are, I
believe, about 4 inches taller to improve yaw stability. Later model
'foxes may have even larger tail surfaces, but I don't know.
In addition, SkyStar modified the flaperon mixer assembly on the IV,
5, 6 and 7 aircraft so that the movement is differential--the
flaperon moving upward moves about twice as far as the one moving
downward, which produces more drag in the direction of a turn.

| Subject: | Jabiru/Kitfox3 report |
--> Kitfox-List message posted by: Michel Verheughe <michel@online.no>
I went flying with the inspector today, here is the report:
OAT: -6C, QNH: 1029. Climb: 1,300 fpm at 70 MPH.
CHT: under 120C. Oil temp: under 70C.
Max RPM: 3,000. Max speed: ... over the red line!
The plane behaves very well, the inspector was extremely pleased in all
aspects, stall, etc. The engine runs perfectly, within the margins of
operation. I have only one problem:
The agent says that I shouldn't "nurse" my engine (the user's manual says the
same). It means that for the first 50 hours, I have to keep the RPM over 2,700.
Impossible! At 2,200 I am already at 80 MPH and If I give more throttle, I come
very quickly to 100 MPH, which is my Vne.
Hum, how do you make you Kitfox more draggy for the first 50 hours? :-)
Conclusion: The Jabiru seems a very good engine and I am very pleased. Lots of
power and a good feeling of a smooth engine. Only two problems:
1) I have some radio noise. People hear me without problem but I hear them with
a background noise. Will check that. Maybe the plugs.
2) I have a leak in the right hand wing tank purge valve. See my next email.
Cheers,
Michel

I am sure I read about it, previously, on this list. But, since it wasn't a
problem for me then, I don't remember the action that should be taken.
I have a small leak in the right hand wing tank purge valve. It drips a drop
every 5 second or so. Enough to worry about the lexan and ... that it might get
worse.
I think it may have come from the fact that the tanks were empty for 3 months.
I have never touched them and don't know how they are installed. Before I start
unscrewing the bolt that seems to fix them, is there something I need to know?
When that is done, is it simply a matter of replacing a washer or something
like that?
Thanks in advance,
Michel

Hello Michel,
I think what you are experiencing is pretty normal as most of the Kitfoxes
in our area have suffered from the same problem.
You can just replace the O'Ring seal and this will normally solve the
problem. (Make sure you use a Gas compatible Rubber O'Ring). Sometimes the
leakage is just caused by debris from the fuel getting caught in the O'Ring
seating area and this can be fixed by pulling the valve out and giving it a
thorough clean.
I have replaced the O'Ring in mine twice in 3 years.
Regards

Mike,
This friend of mine just finished his KF model IV. Upon getting it checked
out for airworthiness they gave him the option of amature built or light
sport built. This also determined the amount of hours he needed to fly the
plane before he could head off cross country. Are you saying he didn't
need to get his plane signed off.

occasionally, it is possible to exercise the drain valve a few times while turning
and clear of small debris. you might want to try that before unscrewing anything.

This is most likely just a piece of debris in the drain valve. Just unscrew
it and inspect it. There is a small replaceable o-ring which you can order
from Aircraft Spruce and such. BUT.... also check your wing sight glass
connector very carefully. If the sight glass connector leaks, and this is a
very common problem and almost impossible to see, it dribbles back along the
fabric and drains out the drain connection. If you smell fuel at the sight
glass this is the most likely problem. You can check it by plugging the
drain valve hole with a plug, and wait a few days to see if it still leaks.
I have had both problems at various times.

Michel congratulations. You must be feeling pretty good about this. OK so
when do we European
Kitfoxers get together? With that speed you can reach a mid European point
in no time at all.
We're going to be finished building some time this summer. The French or
German or Austrian
homebuilders gatherings? I'll work on my french. Anyway I'm getting ahead of
myself but putting
you on notice - and giving us incentive to this thing in the air! Again well
done.

Congratulations Michel!!!
The numbers are impressive! If I get an adequate speed at 2200 rpm, should not
have problem with the temperatures. My question now is: what was your previous
cruising speed? I want to calculate the increase in speed.
I guess you could get some drag by installing an undercarriage cargo pod. Opening
the doors also helps, but is not practical with your temperatures there.
If you need additional drag for your first 50 hours, I think I have the solution
for the provitional gas tanks. There is an option for the Titans consisting
of two external 5 gallons tanks which "hang" under the wing. I have two of those
available. Could be attached under the jury struts. What do you think?
Saludos!

I'd say that flying with adverse yaw is all the fun of the Kitfox. Because if

Er, I was doing 80 MPH with 5,800 RPM. But I am not good at flying-by-numbers.
I am certain that the Jubiru has more power, if feels like it, we had, several
times, to watch the red line.

Yes. Actually, I am sure I can get more drag by installing my skis. The only
problem: during the 28 years I lived in Norway, this is the first winter
without snow! Flying now with skis would be like ... wearing ski boots in
Miami! :-)

Michel:
How it compares the use of right rudder with the Jabiru as opposed to the left
rudder with the 582?

I'd say that flying with adverse yaw is all the fun of the Kitfox. Because if
you forget to use your legs ... man, you're in for trouble when you land! :-)

help me, if the ideal operating rpm can not be maintained without exceeding Vne,
would not a slightly less pitched prop be advantageous?

Yes, I guess it does, Deke. However, when I stall, I already have the stick in
my stomach and I hardly notice the lack of authority on the controls. The
rudder stays powerful, though, and I give opposite rudder to prevent a spin.

Er, I am not sure I follow you, Bill. If say, my indicated stall speed is 40
MPH but, in fact, I fly only say 35 MPH, when I add fly 1.3 times that speed,
it is all relative, isn't it?

He, he! Probably a couple of Norwegian trolls, Rex! :-)
Seriously, I noticed today that my approach speed was high and after flaring, I
was still floating a lot. I adjusted my idle to 900 RPM on the ground. But I
think the engine was still cold. I get 1,100 or even 1,200 in the air and that
is too much, I think, for the landing.

Michel

Thanks Gary, John and Steve. I'll do that. Good to hear it is only a trivial

It is definitively noticeable, Jose. Maybe not as much as I thought it would
when rolling for take off but on initial climb, you need quite a pressure on
the right-hand pedal*. When turning, you are probably used to give more rudder
in a right-hand turn than left, right?** Well, now it is the opposite. It's
just a question of habit. I guess a Cessna/Piper/Continental/Lycoming pilot
will feel more at home with a Jabiru than with a Rotax.
Also a new habit to take: use the carb heater. Today was humid with -6C but dew
point only -8C. I used the carb heater often. Always on final and push it in
when flaring. I have it to the left side of the throttle handle and I can
easily control both with one hand.
Cheers,
Michel
* "right-hand pedal" is a contradiction because "pedal" (as "pedestrian" and
"pedicure") comes from the latin "pedis" which means ... foot ... and not a
hand! :-)
But you know that since you speak Spanish.
** A norwegian ad on the television shows a Norwegian tourist in an Asian
hospital's surgery room, almost gone under the anaesthetic, being asked by the
doctors:
- "Left leg, Sir? Left leg?"
- "... er, ... right!"
- "Ah, right leg! We then cut right leg, Sir!"
- " nooooo!... " zzzzzz! ...
:-)
Sorry for all the off-topic rubbish ... I am still under the euphoria of flying
today!

Yes, I thought it might. Also, I get only 3,000 RPM. I guess, when the pistons,
rings, etc. are settled in, I will be able to go to 3,300 ... almost ballistic!

Well, Kerry, the idea behind installing a Jabiru this winter was to be ready to
fly to Belgium - my place of birth - this summer. I still intend to do it
although I have to make some reservation: after many years trying, our
daughter-in-law is finally pregnant and the child is due late July. The joy of
becoming a grand-father is, of course, overcoming everything else. I think I'll
be able to do a one week trip to Belgian or north of France. But you know how
weather has the habit of making decisions for us. I won't know for sure until a
few days before.

It makes sense to me, Kerr. But my prop is fixed pitch and it is what I got
from the Jabiru dealer, knowing it would be installed on a Kitfox. I am too
much of a novice to pretend I know better than him. Time will show. Maybe I'll
need another prop, although 38 inches doesn't seems much, does it?

I WISH I only saw 3000 rpm. My Prince P-tip just isn't enough. I get 3760 on
climb out alone. On takeoff I'm reducing throttle quickly with the Vernier.
I need a different prop.

Michel,
It is, sort of. If you take 1.3 times 35 you get 45.5. One point three
times 40, your calibrated stall speed, is 52 which is your calibrated
approach speed. You then have to convert the 52 to indicated which will
surely be faster than 45.5. The larger the difference between your asi
stall speed and the calibrated stall speed the greater the difference will
be. In my case the difference is about 4 mph. Not a lot but worth knowing.
I guess the point for me is to be 1.3 above the real stall speed.

Correct me if I am wrong, but couldn't he have been excercising his SportPilot
priveleges? If this news outlet (KTUL in Tulsa, OK) is qouting the FAA rep correctly,
then maybe the FAA needs to send out a memo on the new SportPilot rule.
Surely, I would think that an FAA spokesman would know better than this.
The only explination I can come up with is if the crash took place at night when
SportPilots can't fly. I think this condems the doctor when it is very possible
he was 110% legal. He could have said "all pilots except sport pilots."
Or, I guess it's possible that the media oncve again dropped the ball.Pilot Killed

Doctor's Wrecked Plane Discovered In Hughes County
Search Suspended For Missing Plane, Pilot
Search Continues For Missing Plane
Holdenville (AP) - Federal officials say a Muskogee doctor believed to have died
in the crash of his small plane did not have a medical certificate that's required
of all pilots.
The crashed plane and the body believed to be that of Doctor Jack Nolen were found
Monday in a field in Hughes County. The body is expected to be positively
identified today.
Federal Aviation Administration spokesman John Clabes says all pilots must be licensed
and have a medical certificate before being allowed to fly.
Nolen was last seen January 14th leaving the Paris, Texas, airport on a flight
to Shawnee.
