I have a set of pedals from a model 5. I do not know the difference
between E and C.

Tom=2C Thanks for the info. I have experience with Mikuni and Klein carbs o
n 2 stroke motorcycles. I'm going to hook up enricheners rather than primer
s. You can compensate for lean mixture abnormalities with the enrichners. I
f you keep the enrichner contols seperate you could vary mixture in each cy
linder independent of the other cylinder if egt indicated one cylinder was
running lean. I was wondering if any other 582 drivers had experience with
seperate enrichner controls for each cylinder.

It makes absolutely no difference if the Subaru was originally designed as an airplane
engine 50 year ago or not. The reality is now that the Subuaru that
the poster is thinking about using in his Kitfox is a CAR engine, designed and
built to run in a car, not an airplane. Even IF it were true that some engines
started life in aviation 50 years ago, the aviation engineering that were
put into the engine would have long ago been taken out by an auto manufacturer.
The modern Subaru engine parts were designed to be run in a car at around
20 % power for long periods, not at the long 100 % climbs and 70 % cruise power
used in an airplane.
Bottom line, the history of the engine does not mean anything, the modern design
is for a car, and you will have to do a lot of engineering to make it work at
all in a plane, and chances are it will still probably never be reliable. Many
people with a lot more talent and engineering resources than you have tried
to make these engines reliable for aviation use and failed. It would be best
to learn from their experiences.

| Subject: | Re: Left Side Throttle |
One thing about the proposed left seat/left throttle, right stick combo that no
one mentioned. How are you going to set your radios/GPS/xpnder/ etc., if you're
holding the stick with your right hand? Or are you planning on reaching across
with your left?
This was illustrated quite clearly to me recently ferrying a Pulsar to its new
owner. The airframe was tweaked, such that letting go of the stick meant a slow
diving turn to the right. Combine this with a friction throttle that would not
lock, and I couldn't even scratch my nose for 2 hours. Couldn't mess with the
radio, GPS, nothing. It's no way to fly and have fun.
Most avionics are set up to be operated in the center of the panel and by the throttle
hand. Unless you put all of your avionics on the left side of the panel,
it's not gonna work out too well in practical use.

| Subject: | Re: Left Side Throttle |
I would like to have the throttle as a lever in between the seats. This way I
could site back, and fly, and not need to lean forward to the panel to change
power. I have the throttle on the side in my Kolb, its just like a Jet Fighters
throttle, the throttle lever is where my hand would sit anyways, its really
nice and natural. I don't care which side, but having to reach forward to
change power just seems " Clunky " now.

In the case of the EJ22 rated at 130 HP maximum @ sea level, then the cruise power
setting in the car is probably less than 10% of the maximum, since the car takes
around 12 HP to push it 60 mph on the level. But the engines in these cars last
under
less that ideal operation with perhaps thousands of starts and stops and at low
oil
temperature for 200,000 miles or more. That's probably more than 4000 hours of
operation since the average speed over the life is less than 50 mph.
In an airplane, the engine is nearly 100% of the time operated at ideal operating
temperature with preferred lubrication. It will more often be operated at 100%
power
(sea level, WOT) and will be set to cruise at 65% to 80%. The engine in aircraft
usage
will likely never be exposed to abuse such as over speed (operation in yellow and
past
redline), and is equipped with more instrumentation to insure safe operation such
as
cyl head temperature and EGT instrumentation. The operator will always observe
the
tachometer whereas in a car, there is far more likelihood of abuse such as fouled
air
cleaners, passing recommended oil change intervals limits and the over speeding
the
engine.

I believe, that there is some debate, at least that I perceive in what reliability
means in terms of TBO. There are many factors that contribute to reliability including
redundancy and the design life of the required gear reduction units.

The subject engine is the EJ22 but I think that given the success of a number of
EA81
conversions that a 1000 hour TBO is realistic and that given electrical and fuel
system redundancies, the engine is, in fact, suitable for use in aircraft. There
are
many installations where these engines have been used that have resulted in a
significant cost savings over Certified Aircraft Engines.
I would acknowledge that the redrives (reduction units) have the least known about
their reliability since the number built and the total number of hours of operation
is
far less than for the engine.
Your point is well taken that you are assuming some design responsibility when
choosing this engine, especially as to creating reliable redundancies and the
selection of the redrive.

| Subject: | IVO PROP FOR SALE |
List,
I have decided to keep my Kitfox IV, sport pilot compliant, and decided not
to install the IFA propeller. So it is for sale. It is an IVO light 70" three
blade, in flight adjustable propeller. It is brand new, never installed. I also
have the internal propeller control for 912, and a UHS 9" spinner. I have a
little over $1200 in all this and will sell all for $1000.
If interested please contact me on the list. Thanks

Keep your prop. Regs say ground adjustable=2C doesn't say mechanical or el
ectrical. Put the switch in the engine compartment. Do not put CAP or inf
light adjustable in your log book. Put in ground adjustable electric.

To the list.
Mark and I are finally able to offer the elevator trim tab retrofit for
Model IV and earlier model Kitrfoxes. What we do is a derivative of what
Rans provides for elevator trim - retaining the flat elevator and covering
the servo with a custom made fiberglass bubble cover. Nothing is visible
from the top of the elavator, except, of course the trim tab. See:
http://highwingllc.com/elevatortrim.html for details.

NICE !!! I never liked the flaperon trim of the older models, it is so much more
efficient to trim the airplane from the tail, which is exactly where pitch
should be controlled... I have been wanting to do this mod for my other airplane,
but just never got the time.
With the Kitfox Super Sport, I don't need this, but I would be interested in how
much the parts are which look like they would be a perfect fit for my other
plane.
