Hi Thomas
My model 5 Vixen firewall I am sure is the same dimension as yours.
Measuring from centre firewall base (floor) from top of cross member
up 17 inches.
That is what the manual says.

I'll add my two cents worth here, if you don't mind, Mike.
I spoke with Murle on the phone regarding purchasing a low-fuel
warning system, but I already had the switch, so he sold me just the
receptacle/can, which was very nice of him. Only problem was, when I
got the can, the holes were tapped too large and the fittings screwed
in too far, making sealing them a bit of a problem. After I got that
problem solved, and painted it, I found that one of the end plate
welds was porous, and also leaked. I sent it back, requesting a new
can, but without any holes drilled into it. Murle was very
accommodating, and I'm happy with the overall outcome.

Caution Thomas, the Vixen and all the other Series 5, 6, & 7's are
larger than the IV's. The firewall sizes are much different and the
thrust line may or may not be the same. Sorry about that Graeme.
Why not call the experts at Kitfox?

Thanks, Rick. Yes, I know the Series 5-7 is larger at the firewall.
But if the Series 5-7 manual has the line of thrust I would expect the Series IV
to have it also. Anybody better at finding it than me? It wasn't in the Rotax
582 engine mounting section.
I have plenty of questions for the McBeans. I just figured I'd try this list first.
I didn't think it was that hard a question. But here we are well over a dozen

Thomas,
I built my motor mount for a Lycoming powered S-6. Skystar gave me a
measurement of 15 1/2 inches above the center of lower mount hole for the
thrust line (center of crankshaft). That is what I used. Seems correct.
Measurement is not in builders manual.

My Kitfox II, 582 now has about 10 hours flight time. I have a few issues I
would welcome some advice on. First, my egt at nearly full power (typical
cruise rpm is 5800 rpm to get 70 knots airspeed) runs at 1200 on one
cylinder and 1100 on the other. I have visually adjusted the carb slides to
same setting, but havent tried balancing with a vacuum gauge. The water
temp is usually around 160. What adjustment would bring the egts in line?
Is the 100 degree differential significant?
My GSC 66 in. 3 blade prop is set for 10 degrees. Easily reaches 6800 rpm.
I am thinking of reaming the bolt bore to adjust to 11 or 12 degree pitch.
I have more than enough climb power now. What is the ideal pitch for the
GSC?
Plane is a blast to fly, but I am having to relearn rudder awareness to keep
the ball centered. Needs some left rudder pressure at all times so a trim
tab on the rudder may be needed. I have found the max flap setting at 23
degrees to be useless, 1/2 flaps is more than enough for really slow
landings. Kitfoxers in Flower Mound and Grand Prairie, I have lost your
addresses. EM me so we can go flying .

Sounds like you gonna be in R & D yourself for a while.
I am pretty sure you will want to angle your engine up a few degrees from
centre
line of longitudinal axis. If you mount perpendicular to the firewall them
you will likely have to adjust up once going or have alot of trim on
elevator.
I got a used 912 for sale 6k 1849 hours out of a certified trainer.
Your choice of course. I know that the time proven Rotax engines are proven
to
out perform most other engines s in the Kitfox and Avids so I stick to what
works
well.
I do wish you luck though.

No studs broken off here but I will tell and warn you to make sure you
adjust
to specs when replacing starter onto housing again. The spec is .040 ( 1
mil)
spacing. The starter is rubber mounted. failure to do so and you will
likely
break off the the housing at rear of engine.
I would replace both studs at same time and run your ground to side of
engine block
rather than the little jumper that you likey have. Also buy NEW self locking
nuts.

Yes, starter mount stud breakage is common. If I can remember correctly,
the one
on the left side is the one that always will break. The first one on my
grayhead
broke at about 50 hours, and I just had to replace another recently at
about 550 hours. unfortunately engine removal is the best way to go, though
I
have heard some, repair the starter from the cabin.[/quote]

From: "Mark Napier (napierm)" <napierm@cisco.com>
Hello,
My 582, for the best I could tell, had a little left thrust. Not much.
No down thrust. It looked dead level.
My HKS mount is dead level and strait. As others have said, the
vertical placement of the thrust line (the center of the dang prop)
varies all over the place with different engines.
And not to belabor the obvious, but a corvair engine weighs a bit more
than an O-200 installation. The ones I've seen on Zenith's look a tad
nose heavy and the battery is typically back in the tail. This is way
heavy on a KF-IV. Even a VW engine is pushing it weight wise and
doesn't have good low speed thrust. There is a local guy who has a
KF-IV with a VW in it. He doesn't fly it much. I think he is afraid of
it. The 4-cylinder Jabiru does better. Much more power and less
weight.
I'll admit to not being a big fan of Rotax engines because every dang
nut, gasket and O-ring has a hideous price tag attached. But the power
and thrust you get out of them is great. Even the 2-stroke engines are
reliable as long as you stay right on top of all the maintenance and
operate them correctly.
I don't think this plane is a good match for the corvair engine.
FWIW,
Mark Napier

I don't have a "factory" cowl either. I'm using a custom cowl that fits
the Corvair
engine better than the usual round Kitfox cowls. I can put this cowl
wherever
I want after I get the engine located properly.
But let me see if I get what you're telling me:
1) the absolute height of the center of the crankshaft really isn't
critical, give
or take a few inches; and,
2) whether the center of rotation of the crankshaft deviates from a line
perpendicular
to the plane of the firewall in any direction is much more important;
and,
3) most people nowadays are orienting the center of the crankshaft 90
degrees from
the plane of the firewall in every direction to eliminate unusual
settings.

Thanks, Mark, for your helpful and thoughtful reply. I really don't want to
turn
this thread into an extensive discussion of the merits of various Kitfox
engine/airframe
combinations. If that happens every time I ask a question I'll burn
a lot of months off the calendar and not have much to show for it. Suffice
it to say I did a lot of research before I started down this path. And if I
decide
I want to change engines after I've got it flying, I will be among a large
company of other Kitfox owners who've done the same. And I'll be the first
to
say it wasn't such a great idea if it really works out that way.
That said, if anybody else wants to join Mark with observations about the
line
of thrust, I'm still all ears on that subject.

forward kit including engine mount and a new cowling. I've only owned my
airplane
for 6 months and really feel a need for more horsepower. The 503 is just
50hp. I am also brand new to this site having had Debra McBean direct me
here.
Looking for all the help I can get!

Actually I have given you the answer now
You are in R & D land now my friend. Mark gave you some good insight as
well.
I will tell you that Rotax are a excellent combo for the Kitfox. Other
alternatives
have their pros and cons as well - Jab, Soobs BMW and VW but you will
lose performance overall in most cases and might save a dollar or two?
I would suggest if you want a 4 stroke that your best bang for buk will be
a used
912 6 to 10k plus mount .........
If you want to play with all the others it it not like you are the first to
do
it but the resale of your plane will be less than a Rotax in most cases.
Talk to Mc bean, he will tell you what he has to offer as well.
>> Sounds like you gonna be in R & D yourself for a while.
I am pretty sure you will want to angle your engine up a few degrees from
centre
line of longitudinal axis. If you mount perpendicular to the firewall them
you
will likely have to adjust up once going or have alot of trim on elevator.

I don't know about this last. I said the "current" fad is 0 thrust
angles. However, I don't know if that's what was built in the past,
or if that's what mine is. I also don't know if that's what John's
engine mounts provide.

Thanks, Jay. Any more Model IV owners want to chime in on the location adn alignment
of the line of thrust?
Incidentally, I'm not averse to discussing the merits of my engine choice, but
that discussion could easily consume bits and bytes by the cubic mega-bucket.
I just can't have that discussion every time I need to figure out how to attach
a door handle.

Ed,
You replied to a digest message sending several pages of cruft and did not modify
the
subject to one that is pertinent. Failure to trim the unnecessary cruft out of
list
postings is poor practice.
I'm only squawking about this because it seems to be an all to common occurrence
on
this mail list.
The posting guidelines are appended to every e-mail and it seems they are often
for
naught.
Thank you

max TQ is around 6500. I pitch my prop for 6200-6250 on initial application of
power. This gives me a take off and climb RPM of about 6450-6500 RPM. If I
flatten the prop out anymore, I loose climb. Once in level flight, I back off
to 57-5800 for about 72 MPH ground speed on floats.
Have you checked to make sure the needles are in the same position? Swap the EGT
leads and see if the same side of the gage still reads high, or if if the high
reading follows the EGT sender. I chased a ghost on a buddies plane and it
turned out the sender was hosed up. If the connections that go into the adapter
from the sender or the connections on the back of the gage get tweaked or
the slightest amount of corrosion etc. they will give you goofy readings
Fist step would be to swap the sender wires and make sure the same cylinder is
actually running hot (or colder).
