With pleasure. I bought four years ago a Kitfox 3 with Rotax 582 and
170 hours. I enjoyed the combination for another 100 hours and then I
felt that, while a nice engine, the 582 was narrowing it's 300 hours
TBO and I had to make a decision. Meanwhile, I also wanted to fly
long-distances to e.g. Belgium, my country of birth.
The evident choice would have been the 912; the Kitfox 3 was designed
for both Rotax engines. But, looking at alternatives, I found that the
Jabiru 2200 was very reliable, long TBO (2,000 hours) and needed very
little maintenance. Also, the Jabiru is an air-cooled boxer engine, the
type of engine that has been installed in aircraft for ... nearly a
century.
With my philosophy than less is more, I opted for the Jabiru and the
engine lived up to all my expectations. I have now 240 hours on it.
However, here are a few points to remember:
1) The Jabiru won't fit in the Kitfox 3 without modifying the cowling.
There are several solutions; I opted for re-moulding myself the entire
front end.
2) The key to a well running air-cooled engine is to provide a good
cooling by shaping properly the cowling. If anything, mine does a
perfect job, even cooling too much on e.g. long descent.
3) Jabiru build their engines to fit their Jabiru aircraft. If you want
to be safe, you should try to reproduce as much as possible a Jabiru
installation. I use the Jabiru airbox, Jabiru oi-cooler, Jabiru prop,
etc. Some people think the know better and install the engine
differently. It's often them who have problems later.
4) The Jabiru runs WOT at 3100 RPM, twice as slow as a Rotax. It means
less engine wear but also less torque and while the 2200 has 20 HP more
than the 582, its climbing performance isn't better. But, at cruise
level, I keep 85 MPH with as little as 2,600 RPM.
5) Because of the direct drive and air-cooling, the 2200 is only 12 kg
heavier than the 582. I didn't need to change anything to keep the CoG
within the marks. But the direct drive means that the propeller's
choice is very limited: A two-blades wooden prop is what should be used
although some composite props are coming on the market too.

Travis, I can't say much more than "Go For It"! For long trips there is
nothing like having an autopilot, especially at night, in turbulence, and
when you need to spend a lot of time referencing charts, keeping your
outside scan going, etc. IMO, one of the biggest advantages is the backup
safety factor you have if you ever get stuck on top of a cloud deck while
low on fuel, haze over water, or any other situation where you find yourself
with big problems and need to keep the wings level. I have the Tru-Trak ADI
artificial horizon (no a/p) and about all I can say about it is that it
works perfectly and factory support is superb. I have it interfaced with my
Garmin 196 so it also reads the ground track on the digital readout. It's
even cheaper than the RC Allen units that work for a short time then have to
be sent back for repair.
Good luck and keep us apprised of your progress.

Michel,
Great report on the Jab vs the 582 , totally un-biased from a guy who has had
both engines and ran both with great success!!

Pedro,
Where will you be operating your amphibs on land?
Reason I ask is that rough fields will severely shorten the life of your gear
as most are ok but they will fail in time. I have hundreds of gear landings on
my Aerocets on grass runways and I have to continually do maintenance to them.
They are a great aerodynamic float and great handing on the water and a good paved
runway floats but they can cause you grief like any Amphib float can especially
is opertaing on non-paved strips and seaplane ramps.
How does your Vernier engine compare to these videos ?
Reason I ask is that the float will definalty slow you down and really cut your
performance level.

Michel (and any other Jabiru 2200 enthusiasts),
Not sure if you ever wander over onto the Avid Yahoo site or not, but if not
I think this e-mail from one of the Jabiru Avid (aka; JAVID) guys has really
shown some great results from his install of the 2200. After reading all of
his postings over the past year or so, I think he has the figured out the
right prop combination for the Jab 2200 on STOL airframes like Avids and
Kitfoxes. It seems his Avid is outperforming most all other JAVIDs out
there. So maybe this info could be useful to others. I know Lynn Matteson
right here on our group has also been verys successful with this 2200 in his
Fox (Btw Lynn - NICE article in Sport Pilot!), but thought I'd share this
for anyone else that might be considering a Jab 2200.
I have to admit I was one of the biggest naysayers out there about using a
Jab engine in our airplanes, as I really like the 912. But I'm pretty well
convinced after hearing (and seeing) abot them more from people that own
them, they offer another good engine option for out favorite Avids and
Kitfoxes. Especially on the earlier and lighter airframes. So here's what
the owner of a Jabiru powered Avid B-model has to say about his airplanes
performance;
(and for video proof of what he states, check out the YouTube video he
posted at http://youtube.com/watch?v=raAV2r3LSgU ) Pretty impressive!
******original message from skypics234@aol.com******
My Avid is...
Model B
STOL wings 29.9 feet
Empty weight 550
My weight 160
Jab 2200 with hyd lifters @ 85 HP (430 hours) These engines don't peak out
until after 50 hours break-in.
Prop is Tennessee 64 x 36 wood 5 pounds (beautiful workmanship)
T/O and climb out RPM 2900 & 70 MPH
Climb rate solo 20 gallons is 1300-1400 FPM at 70 M PH (70 F OAT) 1000-1100
at 80 MPH
cruise at 2800 RPM and 3500 MSL OAT 65F is 95-100 MPH TAS at 3.0-3.2 GPH
At 12,500 MSL (45 F OAT) cruise is 105-110 TAS and 2.8 GPH
Add 10 MPH to cruise speeds and subtract 200 FPM climb using a Sensenich 62
x 42 (moderate workmanship) borrowed from a friend.

Can someone explain the reasons for having the big capacitor in the electrical
system on our kitfoxes? My diagram shows it on the discharge of the alternator...is
this simply to even out peaks from the alternator or does it serve another
purpose? I am running a dual alternator setup and don't expect to use the
onboard alternator much at all (only if the primary dies on me) so is this capacitor
really necessary? If this is an ignorant question, please forgive me
as I am really a complete novice when it comes to electronics.

It should suppress any electrical noise you might get. Should probably
have one on each alternator. If your not getting any noise then you
probably don't need them.

Thanks, Paul. I like my Jabiru engine, but with my current prop...a
Sensenich 62x46....my climb rate is not as good as John M's, but my
empty weight is 110 lbs more, and my prop is much steeper than his
Tennessee, and a little bit steeper than his borrowed Sensenich. And
I guess the Avid will outclimb the 'fox IV, given the exact same set
of circumstances, won't it? My climb rate of anywhere between
800-1200 fpm, depending on OAT, is usually less than reports of the
912 family. I'd really like to try a different prop, and I may
someday, but for now, I'm reasonably happy with what I've got, and
I'm not too interested in chasing the numbers at this time.

| Subject: | Re: Capacitor in Kitfox Elec. System? |
The capacitor in your ship's wiring diagram is a very important component.
It filters or "smoothes" the output voltage pulses from your alternator
before voltage spikes or "bumps" can do harm to your voltage regulator or your
avionics items. It is also a component that helps to accomplish voltage
stability in your voltage regulator and to your entire electrical system.
Consider comparing that capacitor to a large water tank:
In the bottom of the water tank is an open valve for drawing water (ship's
power). Voltage pulses from your ship's alternator are like buckets of water
being added to the water tank (capacitor). The stream of water coming out of
your water tank's valve is smooth and little change in water volume or
pressure is noted as each bucket of water is poured in to the top of the tank.
A
voltage pulse from your alternator is stored in the capacitor in much the
same way that a bucket of water is stored in the water tank.
During the time that the alternator's output is zero (the time between
output pulses), the capacitor supplies an even voltage to your electrical system
with little droop in output voltage. During the time that the alternator's
output voltage pulse is well over nominal voltage, the capacitor absorbs the
spike in much the same way as the water tank that has a larger than normal buck
et of water dumped in to it. The output water stream "feels" little change.

John,
This is what I understood the capacitor to do. Then the question is...should I
have one of these on both alternators? And what size should the second on be
(40 amp alternator output)?

I think the type of noise you want to shield is in the circuit and not
what is generated from say weak plug wires. At least that was my
understanding. I know there are folks way smarter on the subject than me
though.

Yes. Size is not critical. Two of the same would be fine. You could even
share the cap. with both alternators if your configuration is to switch out
the primary but failed alt. and switch in the back up one.
If your intention is to have two complete and independent power sources you
will need two alternators, two filter capacitors, two regulators, two
batteries, a primary and an alternate power bus, etc.

When I build my Kitfox, I'm planning on installing a C-85. I have the
engine - freshly overhauled to new specs - so that drove the choice of
engine. During the overhaul, the O-200 crankshaft and pistons were
installed - which makes it effectively an O-200 (100hp).
Who else has installed heavier engines like the C-85 or O-200 and what
issues were encountered? What props were chosen?

I can confirm that. Once, my TruTrak turn coordinator didn't work
(stayed blocked in a turn) and I sent an email to the factory asking if
they could service it and how long it would take. Two hours later I had
an answer: Send your instrument and we send you a new one immediately!
Now folks, you have to understand that I live in Norway and that it is
not usual to get such service across the pond. This was fantastic!
To end the story, I went to the hangar to remove the instrument, then
decided to try it again just once. It worked this time! The mistake was
mine: I don't have a switch for the instruments. When I start my
engine, the TruTrak is on but suffers a voltage drop. That, sometimes
(it has only happened twice in maybe 150 starts) can cause an error.
It's then a simple matter to switch it off and on again.
Anyway, I am very pleased with the instrument and the service from that
company. I can recommend them.
Cheers,

Lockwood sells a special restricter that does the trick. It screws into th

They also told me how to start my 912ul by just using the primer and not th

hrottle a quarter of an inch. Hit the starter and at the same time, inject
one more primer load. Should start up just as nice as can be!!! Sure has
eliminated hard starting for me. If the plane has been setting for quite a
while (gas out of the system), I usually squirt about three primer loads in
to the carbs first, and it may need another couple of squirts to keep the e

Thanks for sharing, Paul. Yes, I think it is a good engine but -
contrary to what Marco wrote (he might have been on an overdose of

'up there' without really measuring how and why.
I went for a few touch-and-go today (the first flying weather in

engine. Of course, all conditions were perfect; temperature just above
freezing, me alone and little fuel. I was taking off and in a steep
climb without even understanding what was happening (only a form of
speech, my friend! :-).
I am also sure I could climb even better if I had a prop with a lesser
pitch. But I fly from a 2,400 ft asphalt runway and no obstacle in its
axis; I could even take off by flapping my arms, if I had to! :-) The
propeller I have was recommended to me by the Jabiru dealer as a good
compromise for economical cruising and I am very pleased with it. The
only thing, though, is that the Jabiru wood props are not taking rain
very well. Mine is still fine but I know that I should be looking for
something slightly better because ... it's not easy to avoid rain in
Norway! :-)

I've been lurking for a while and will be ordering a Kitfox in March. Time
to come out of the woodwork, I guess.
Kirk, you are correct under most circumstances. But if you have made any
lengthy trips, you will know that an autopilot really makes the trip much
less tiresome. It's really great when you have 4 or 5 hours of flying to
do, to be able to just plug in the flight plan and then sit back, relax and
monitor progress and status rather than having to hand fly the plane.
I love low and slow, but sometimes, it's just the getting there that you
need to do. I'll be putting an ADI Pilot II in my Kitfox, so I'm really
interested in this thread.

Deke,
Glad to hear that you and Michael have been pleased with your ADI products. I
hope my experience is as positive!
Michael...Have you considered installing a main switch for your electronics? If
they have power going to them during start-up and shut-down the voltage spikes
can be brutal on them. It's generally not if...but when! [Shocked] I'm glad
you realized your unit was OK before you pulled it out and sent it off!
I ordered the necessary wire last night. The ADI-II comes with all the plug in
connectors but no wire. It will require 15 wires running from the ADI head to
the servos. The directional servo takes 7 (five 22 gauge & two 20 gauge wires).
The vertical hold servo takes the same plus 1 extra wire. Stein Aircraft
sells a wire bundle, the 5/2 combination as noted above, for $1.30 per foot
specifically for the ADI autopilot installation. I estimated...although rough...
10 feet for each servo...20 feet total. I ordered 24'! I'd much rather have
several feet extra...than be 2" short!

Thanks guys for the info. I have installed the optional alternator because the
onboard one is not quite enough for what I have. So rather than simply let the
onboard alternator sit unused, I have wired them on a switch and relay so in
the event that my primary alternator goes, I will at least be able to operate
my primary electronic items. The other alternator has the regulator built in,
so I have two regulators and two alternators but only one battery.
I like John's idea of sharing the capacitor between the two as I will never have
both alternators providing power at the same time.
Thanks,
