Good onya John, a few domestic chores sounds like a good deal to me. I have
to admit I like the idea of something other than glue holding the fabric on.
I was surprised how easily I was able to strip the wing. The fabric came
away using very little force.

Your numbers seem fine, Kirk. My Model IV-1200 Speedster weighed in
at 660 pounds with a 100 HP Rotax 912ULS and Ivo medium prop. After
I installed the wheel pants she could hit Vne (140 mph) in level
flight with full power. High speed cruise was around 125 mph at 5.5
gph or a more sedate 115 mph at 5 gph or a bit less. She'd fly on
3.5 gph, too, doing about 75 to 80 mph.
My 'fox was FAR from stock--we had even changed the shape of the
empanage with extra tubing--and she had nearly every kind of speed
fairing known to man, so your mileage (and performance!) will vary.

My manual suggests that it is strongly suggested by both Poly-fiber and
Skystar (remember them?). I like the look, as I'm old enough to
remember the older rag and tube planes, and it's fun to get the wax on
your wing (from the rib lacing). Besides, I figured that by rib-lacing,
I'd have a little more drag on my wings and that would slow my Jabiru
2200-powered IV down to where you 912'ers fly. : ) : )

Why is your VNE so much higher than mine? The red on my speedo starts at 125. I
always found it kinda scary to have a cruise speed that is only 10mph slower
than VNE. If I get any kind of updraft, I have to ride it out and let her climb.
If I try to hold altitude without working the trottle she'll blow right by
VNE in a jiffy.

Subject: | Checking the oil on a 912UL |
--> Kitfox-List message posted by: "wingnut" <wingnut@spamarrest.com>
The procedure for checking the oil that is detailed in the operators manual involves
hand proping for a few minutes to pump the oil from the engine into the
oil tank. This is a pain in the neck and I was wondering if anyone out there knows
of an alternate procedure.
The previous owner suggested that I just check the oil after shutting down at the
end of the flight. Does that sound reasonable?

What I've always heard is that you should check the oil after a minute or two of
having the engine run.
It is much easier on the engine to pre-heat it, if it is below 35 F.
Checking after the flight is okay also, but you then have to check for puddling
(on the ground, in the cowl, etc). Personally I've been checking after engine
1-2 minute warmup.
This summer, I am going to modify my cowl so that I won't have to remove it when
I check oil. That *my* only complaint.

Ouch. I guess I'm lucky that the builder of this airplane put in a access door
over the oil tank. Thanks for the tip. I think I'll switch to checking after warmup.

Do you guys really fly around so close to Vne? (I.e. well into the yellow
arc?) I guess you've got more guts than I do. Or do you have some
information that says it's safe?
Thanks,

I can't figure out what you are trying to say here. You say you get an updraft
and then your all of the sudden over VNE? What is your cruise speed? Are you
just getting extra reading on your speed indicator that isn't reflecting on
the whole airplane? My VNE is 135 as per the short wings, medium fabric(stitched),
120 windscreen, and two weights on each aileron. I cruise at 110 at 5200rpm
IAC. When I land I go up to 135 IAC until about 1/8 out all the time. I
don't think I've seen my airspeed jump up in turbulance, I don't stare at the
guages, I'll watch the next time I get an updraft.

When I did mine it was a pain to do the continueous stitch. I ended up doing the
starting stitch and cut off and do the next, got real fast at doing it that
way. All I can say about stiching is, you can do it now, but not later.

I have 750 hours on a 5 without rib stitching and no problems, I have
rib stitched and used big head rivets. If glued correctly to the ribs it
should be on really well. I used rivets on the last planes I have done
and like it the best, but rib stitching is fun, provided of course that
you do not rip the fabric.

I guess you've got more guts than I do. Or do you have some information that
says it's safe?
It's my understanding that, as long as you're flying in smooth air and you don't
make any abrupt control movements, there's no danger in flying near Vne. That
said, for me reach 115, I have to ajust the IVO prop for best cruise. While
I can do that with a switch, I still don't bother unless it's perfectly smooth
air and I'm actually going somewhere instead of just having fun.
Also, don't these numbers come with a certain amount of safety factor built in?
While you don't want to excede it on purpose, Vne isn't a hard limit at which
point you will abruptly loose your wings. I would not be here if that were the
case.

I'm mainly thinking of a cross country I did this weekend. Being a student pilot,
I was probably being a bit too aggressive in my attempt to maintain the planed
altitude (won't the examiner ding you if you blow it by more than 100 ft?).
At one point, I entered a moderate updraft and I responded by pitching down
ever so slightly to maintain altitude. Even though I was still climbing, it only
took a couple of seconds for that little bit of pitch correction to add the
10 mph I needed to hit VNE. Naturally, I throttled back at that point and gave
myself some breathing room but it was still scary.

Ah! the days of flight training.
When I started out I did it with both the cessna and the fox. I remember my flight
instructor telling me to throttle back in the fox because I was going over
5800 rpm all the time. Now days 350 hours later in the fox. I know what it's
doing without looking at the guage and do things without thinking. I guess you
can always go into a slip and lower the altitude and still stay on track.

Your numbers seem fine, Kirk. My Model IV-1200 Speedster weighed in
at 660 pounds with a 100 HP Rotax 912ULS and Ivo medium prop. After
I installed the wheel pants she could hit Vne (140 mph) in level

Brett. If it is a 912 install in the Model IV, I have some photos I took
for another builder. Not knowing exactly what you want to see, I don't know
if they would be that helpful, but if you would like to see them drop a

Kirk,
If you have the time, some of us would like to hear
how your Stratus powered Fox performs and how you like
it. Any problems?

I am not a builder (yet), but I picked this up to become more familiar with the
kitfox I purchased. I have found the video to be extreamly helpful to me. I
would highly recommend it.
Actually, I believe I got it as part of the donation to this news group.

Who in the Southeast US has a Classic IV that will let me come and take some pictures
of the engine install? I am just getting rolling and the manual is not
really that much help. I know there are a couple in the Carolinas. What do you
say? Road trip?
Eric, I need more pictures of yours as well.

On cross countries, I find that if I want to get
better milage in my Fox, I can ride the thermals down
low and get an extra 10 mph or so. If I get tired of
the bumps, I climb out of them. Makes it better to
read the map. I usually cruise at 100 mph in my S-5
in smooth or rough air. It just rides more
comfortably at that speed.

Do to personal reasons, I am selling the Model 1 I bought on eBay in MI. It is
still in the enclosed trailer that I picked it up with in January (including the
amphibious floats). I paid 17100 and I am not looking to make a profit. Do
you have interest or do you know someone who has interest? Last annual was 6/5/05.

Matt,
I don't have any numbers in front of me, but I think Corvair engines would
be way too big and heavy. Those are opposed 6 cylinders, and not built for
light weight. Add to that lack of parts availability, wide size, and the
fact that they leak a quart of oil an hour. I don't think they make good
airplane engines.

From what I have found out is that they weigh somewhere between an
O-200 and and O-235, and make a little better than 100 HP. It will fit
inside the large cowl on a 5,6,7 series plane. It is an interesting
option. They are getting some flight hours and it appears they have
promise. With the cost of Rotax and others getting out of reason it is
worth considering. Remember thought that anything other than factory
supported engines will cause you problems in insurance and will really
hurt resale.
They have a lot of information on their web site www.flycorvair.com

Hi John,
What out side temps are you commonly flying in now?
What engine temps are you seeing in flight?
What will be the highest temp you would want to fly
in?
Those are needed to know whaty to design for.
One of the problems with the smiley face opening is
that it is in a very low pressure area of the cowl.
The ram air effect is hardly able to overcome the low
pressure outside due to the curve of the cowl. This
area is like the upper surface of the wing, except
inverted, and made worse by the side curve of the cowl
too. Very low pressure results. The air inside of the
cowl is usually under higher pressure from the front
inlets. This allows the lower outlet to work. It may
not be so with your inlet to outlet pressure for your
radiator.
With a smiley face inlet, the pressure at the back of
the cowl where you want the air to go out is actually
at higher pressure, so the air almost wants to reverse
flow in and come out the smiley face! The smiley face
is not the best inlet air location we can get.
When I first flew my NSI powered S-5 it was just cool
enough outside to handle it. That was in the 60's F
range. I have the big alum. radiator but a slightly
smaller oil cooler than standard. My initial problem
was oil temps going high (235F), so I added more
airflow and can now handle into the low 90's to keep
the oil below 220F or so. I did this by enlarging the
smiley face to 1.5" and directing all the flow to the
oil cooler, which is below the firewall. It works
pretty good in flight, but gets hot taxiing a long
time.
My radiator temp was the next problem. It was OK into
the 70's, but draggy hanging out by itself. I added a
scoop and gained 9 mph, but still have to work on
making it run comfortably above 90F and while on a
long taxi. The exhaust size from my scoop is critical
in keeping the temps down, but I am looking at adding
VG`s in front of the scoop to see if that will help
too. The scoop takes in boundry layer air and that is
messed up quite a bit.
Your scoop inlet up front looks pretty good, but as I
said, that is a low pressure area. The outlet should
ideally be in a lower pressure area than the inlet.
Neither of us have the ideal. You might want to make
up 3 VG sets and tape them in front of your inlet
about half way up to the prop to see if that helps.
It is a very easy fix that need not be perminent until
you know that it works.
After that, you may need to add an outlet door that
increases the opening when needed. That will be my
next step after the VG's too.
I learned about using the VG's from a canard with NACA
scoops to the engine that was overheating. VG's saved
the day for him.

There is a KitFox-6 with a corvair engine being built
in KY by a Barry Bannon (sp). He had the engine
running last I heard, but was a long way from flying
yet. I don't have further info, but he should show up
on the Corvair list.

That is a good explaination on the smiley face. I tapped mine up because it
just took air in and back out. Flowed over and around nothing. So to improve
the inlet to outlet ratio blocking it was the logical solution. I tested my
cowling flows with a water hose behind the prop and infront of the
radiators. That is when I saw the airflow going around the radiators and
some going in the back. That is when I put the cowlings on. That made a big
difference. There are actually bugs hitting the radiator now.

Hmm Kurt, I thought that area is still pretty high pressure still where I
have the inlet and where the radiator is is low pressure. If you look at the
cowel around that area, thats were all the bugs hit and that's usually hight
pressure. The plenum area to the radiator is seperate from the engine air
except for the lower part of the sump (cooling piped and finned) and this
sees the radiator air also. My temps are oil, around 190 F approx (we all
C here) and water water 210F approx 110C. I also have an Earls heater
cooler also in the heater circ which is hooked to the water/oli cooler and
turbo. I've opened the exit area to the main cowl a bit so hope this will
enhance the airflow to this radiator and help the intercooler as it exhausts
into this area. The OAT is around 23c. John

Yes, smiley face....My inlet area is about one third of the radiator area
which I read is about the right ratio?? And bugs sure do hit the inlet area
and the radiator gets full of grass on the front so I'm pratty sure the flow
is there but I'll try your hose trick Albert. I'll put so shots on

I'll soon be able to give more on this subject to those who are
interested in the Corvair Fox combination. Hopefully before the end of
next month. I'm not sure of the "total" weight yet, but feel positive it
will be near the 0200. Parts are readily available from two parts
houses that specialize only in Corvair parts. One is on the East Coast
and one on the West Coast. Hear is a good place to start looking if
you are interested in all that has been done to perfect the Corvair
engine. http://www.flycorvair.com/ <http://www.flycorvair.com/>

There are several more interesting sites you can find, or I can send

I guess you probably should contact me off list. I'm not affiliated in
any way with any product pertaining to Corvair engines or otherwise.

Bruce - Sorry to here your selling that beauty. Tempting since mine is still pretty
far from flight ... but ... personal reasons require me to be a one plane
man. Someone here may have interest. This list strips attachments including
photos. Someone may have a suggestion for how to share your pics. If you have
any extra parts... like a header tank I'd looking for one.
BTW - I got lucky and now have a construction manual for my model 1 - the prevouis
owner came across it and relayed it recently.

not be so with your inlet to outlet pressure for your
radiator.
With a smiley face inlet, the pressure at the back of
the cowl where you want the air to go out is actually
at higher pressure, so the air almost wants to reverse
flow in and come out the smiley face! The smiley face
is not the best inlet air location we can get.
When I first flew my NSI powered S-5 it was just cool
enough outside to handle it. That was in the 60's F
range. I have the big alum. radiator but a slightly
smaller oil cooler than standard. My initial problem
was oil temps going high (235F), so I added more
airflow and can now handle into the low 90's to keep
the oil below 220F or so. I did this by enlarging the
smiley face to 1.5" and directing all the flow to the
oil cooler, which is below the firewall. It works
pretty good in flight, but gets hot taxiing a long
time.
My radiator temp was the next problem. It was OK into
the 70's, but draggy hanging out by itself. I added a
scoop and gained 9 mph, but still have to work on
making it run comfortably above 90F and while on a
long taxi. The exhaust size from my scoop is critical
in keeping the temps down, but I am looking at adding
VG`s in front of the scoop to see if that will help
too. The scoop takes in boundry layer air and that is
messed up quite a bit.
Your scoop inlet up front looks pretty good, but as I
said, that is a low pressure area. The outlet should
ideally be in a lower pressure area than the inlet.
Neither of us have the ideal. You might want to make
up 3 VG sets and tape them in front of your inlet
about half way up to the prop to see if that helps.
It is a very easy fix that need not be perminent until
you know that it works.
After that, you may need to add an outlet door that
increases the opening when needed. That will be my
next step after the VG's too.
I learned about using the VG's from a canard with NACA
scoops to the engine that was overheating. VG's saved
the day for him.
