WOW Jeff,
That is about a years worth of links and references to
study. Overwhelming! I am going to dig out what I
can in the time I have, but this goes far beyond KF
flying for useful info. Thanks very much.
I don't mind doing the foam strut work too much. My
S-5 has a foam/fiberglass fairing at the front of the
verticle stab and the leading edge and the center rib
in the verticle stab are foam too. I liked it better
than the wood ribs. Better shape for light weight.
It doesn't appear that your struts have any boundary
layer controls such as turbulators. Is that correct?
I expect that I may need these from our computer
studies for low Reynolds #'s. We will see...
A long time ago (1975) I tried electric RC and it was
pretty humble. I still have what remains of the .25
size plane down stairs. If you got 2 minutes of weak
motoring and a 3 minute flight, you did great. I then
designed and built a canard model in 1976 similar to
the Velocity. Still have that too. Never finished it
enough to fly, just taxied on electrics. The engine
was too weak...
Now I saw a movie on that "nesail" site of yours that
just floored me. A 17 yr old boy flying a plane off a
table and doing every stunt including hovering with an
electric plane in his basement! Talk about confined
short field work! This movie page is a must see.
Here is a direct link:
<http://www.nesail.com/videos.php?PHPSESSID=3e7df90b87cd64af7751598effd901c3>
Makes me want an electric KitFox. We may see such a
thing full size in our lifetimes too. No mufflers, no
carbs, just amps... Turn it on and go fly. There was
a group at OSH last year that has already started on
such a project expecting 500 miles of range on
electrics!
Thanks for all the info,
Kurt S.

Hi Danny,
Would you be so kind as to tell us how your plane
performs with the Stratus and your likes/dislikes of
it? I haven't heard too much from those who bought
the Stratus on this site and I am sure others are
curious too.

Cliff:
I have friend that is building an Airdale and has considered the 0-235 as an
option. I'd like to see him get the right engine for his airplane, so I
thought your info may help. I'm curious what the empty weight is on your
airplane (since you obviously are very happy with the performance). And
what prop are you using? Is yours a long wing?
Oh, and don't hold back on telling the list here how you get that great
cruise on that low fuel burn....

Yes. Try new plugs or swapping them around. Also try swapping the egt

Hello Guy,
I have been considering the sale of my Model IV Speedster. If you would
like to contact me off list we can discuss the craft. Should you prefer,
send me your telephone number and I will call you. I am located in
upstate NY and right now the airplane is in a hanger at a private airport
which is snowed in. Probably can't get it out until April.
Look forward to talking with you, I think I can answer the questions you
have.
Best regards.

Right, Torgeir. As Elbie writes in a direct email, it's probably because the
previous owners didn't had a transponder (correct!) and flew in uncontrolled
airspace (correct!). Indeed Tango flew all these years from Stryn* and the
only radio-requiring trip was to Sandane* airport. Typical bush / mountain
flying with no need for accurate altitude.
> Is your "Tango" free of vibrations??
Howww w ww wwould I III knowww www? :-) I have so little experience with other
planes. But I think she is quite ok, otherwise my instructor would have
mention it. She is, at least, quite silent for a two-stroke lady.
The "erratic" speed indicator is not that much vibration but more "sticky"
movements. I wonder if the needle needs oiling or something like that. What do
you think?
Cheers,

One thing I noticed after landing was that my trim was
full nose up. I trimmed for 52 KIAS this time and
that shows me that I am right there at the fwd CG.
I'll have to see if I can even use full flaps, or any
at all, for landing without running out of elevator.
I landed with 69# of fuel at 1200 lbs total. I
couldn't catch it, but the stall in ground effect was
below 40 KIAS somewhere clean.
Now I wonder if I am actually stalling the wing or
running out of elevator at altitude. I'll have to
explore the stall deeper, then start moving the CG aft
with more weight.
Try using a gap seal on the elevator.

Can't answer this for you. A friend has a IV-1200-912 that weighs 604
empty. Mine comes in at 704 with a lot of fairings and stuff. I can beat
him easily in cruise, and my climb is minimally less than his. Lighter is
always better, though.
> 2. Should I hold out for a 1200# gross weight?
Yes
> 3. Is a 582 adequate for two, or should I pay for the 912?
My advice is go for the 912. Lower fuel consumption - longer range. Less
to tinker with. Another friend had a 582 powered IV and it was cowl off at
every fuel stop, fly over roads at all times, if possible, had to fly
thermals in the mountains to make ridge crossings etc. It is a good
reliable ingine, but needs more TLC.

Depends on your use. Transponder if required in your area, that sort of

You can find this out by typing the engine serial number into a page on the
Rotax Owners Association site. It will give you all the appropriate service
needs for that engine. Quality of construction, control slop, that sort of
thing.

Hi Kurt -
No problem on the links. With regard to the struts, I went the
simple and expedient way, I called somebody who does a lot of work
with aerodynamics, said what I was doing, and what would they
suggest? I then simply hacked it together. I suppose you could
gain some small percent improvement by wind tunnel testing, etc,
etc. But to me the minor gains just don't seem worth the work.
However, that said, I do a lot of things just for fun, that are
technically not worth the time spent ...
Definetly, they save weight over the PVC fairings with the Kit.
I met Sal DeFrancesco via RC Sailplanes which I used to be into
in a major way, I still have a half dozen or so 2 meter class
composite planes in the attic, but have not flown them in a
good ten years. The RC sailplane's are drastically beyond what
most people realize with regard to technology, and anybody that
wants to learn somehing about aerodynamics would well benefit from
studying them.
Best Regards,
Jeff Hays.

WOW Jeff,
That is about a years worth of links and references to
study. Overwhelming! I am going to dig out what I
can in the time I have, but this goes far beyond KF
flying for useful info. Thanks very much.
I don't mind doing the foam strut work too much. My
S-5 has a foam/fiberglass fairing at the front of the
verticle stab and the leading edge and the center rib
in the verticle stab are foam too. I liked it better
than the wood ribs. Better shape for light weight.
It doesn't appear that your struts have any boundary
layer controls such as turbulators. Is that correct?
I expect that I may need these from our computer
studies for low Reynolds #'s. We will see...
A long time ago (1975) I tried electric RC and it was
pretty humble. I still have what remains of the .25
size plane down stairs. If you got 2 minutes of weak
motoring and a 3 minute flight, you did great. I then
designed and built a canard model in 1976 similar to
the Velocity. Still have that too. Never finished it
enough to fly, just taxied on electrics. The engine
was too weak...
Now I saw a movie on that "nesail" site of yours that
just floored me. A 17 yr old boy flying a plane off a
table and doing every stunt including hovering with an
electric plane in his basement! Talk about confined
short field work! This movie page is a must see.
Here is a direct link:
<http://www.nesail.com/videos.php?PHPSESSID=3e7df90b87cd64af7751598effd901c3
>
Makes me want an electric KitFox. We may see such a
thing full size in our lifetimes too. No mufflers, no
carbs, just amps... Turn it on and go fly. There was
a group at OSH last year that has already started on
such a project expecting 500 miles of range on
electrics!
Thanks for all the info,
Kurt S.

--> Kitfox-List message posted by: "Kerry Skyring" <kerryskyring@hotmail.com>
Hi Albert,
I can't answer your question but I can share experience.
We've just gone throught the process of putting the sealing
strip around the firewall. (series 5 rotax 912) Ended up throwing away the
rubber
strip that comes with the kit and used the stronger aluminium reinforced
sealing strip that's used for the continental installation. Just couldn#t
get a satisfactory glue for the rubber to the stainless steel
firewall. Anyway we are trying to get a nice tight seal, we have
the smooth cowl, but don't know how critical this seal is. I guess a bit of
silicon could fill in any holes but I am also interested in any
real life experience in this area. We are living in a Kitfox
free area which makes it a bit difficult to check things like
this.

Hey Fellows,
Special Thanks to Lowell & Kurt for their suggestions on finding a cowl
cover for my Arctic Fox.
Lowell, I contacted KENNON and they are willing to work with me on
making one up for me.
They are a Canadian outfit and a fellow in Kenai, Ak. (Paul Dale) says
that his cover works pretty good.
(Paul's Series V was built up in Kotzebue a couple of years ago which is
COLDER than Nome if you can believe that)
I'll keep you updated as some of you may want one of these too. Yes,
I'll post some pictures.

I know this issue is about three weeks old, but my 582 is having that
same kind of power loss, again. (RPM slowing down to 5100 to 5200
on ground roll ) I was wondering after all the suggestions, if it solved anyones
problem ?
I had this problem a year ago december, 2002. My first thought was the
fuel sence it was over 60 days old. I drained both tanks and header tank,
and replaced with fresh fuel, purged the lines, done a fuel flow test, it
tested at 12 gals an hr. fuel pump was working, checked floats in carbs.
OK, installed new plugs, even put in new battery. none of this worked !!
After a suggestion to call an authorized Rotax dealer and explain the
problem. He said the Nut on the Tapered Prop shaft that is connected
in the Gear Box, needs tighten'd. He said he's tighten'd 100's of them,
and no doubt , that is the problem. Took off the gear box, after draining,
went to town to find a big mechanic with a big wrench. He put all he had
on the wrench and felt like it was tight as it could get. ..... Reasembled
everything, went to fly, and the same thing. power loss on ground roll.
called Rotax again, the same guy said I needed a cheater bar and put
more grunt into it. This time the wrench is 3 feet long. reasembled ,went
to fly, and still the same thing, Called the Rotax guy again, and he said
to put a longer cheater bar on the wrench, 4 or 5 feet if necessary. A Pilot
friend of mine who weighs 240 lbs was on the end of this 5 foot wrench
giving it all he had. nothing broke !! I was surprised !!! Reasembled, went
to fly and still the same thing. I didn't call Rotax back. and a funny thing,
I asked the Rotax dealer and shop mechanic at the time if it could be the
fuel, and he said,no way. Well, to make a long story longer. My 240
lb friend suggested to re set the neddle jet to a different setting, I said it
won't do any good,after all,I was told from the true source that wasn't the
problem. I moved the Jet one knotch, and the 582 has performed
perfect ever sense................. Until now. I installed new plugs, changed
the Jet needle setting in the Carbs, from full rich to next to full lean, and still
nothing helps. What worked before, doesn't work now.
What do I do now ? Help !!!
At 5100 RPM the 582 developes 43.6 HP. Enough to still fly the Kitfox,
which I do. After reaching pattern altitude and level off, I put the nose down
the engine picks up speed, and from there on the engine performs just fine.
Until the next ground roll. and then the same thing, until I get to pattern
altitude and put the nose down.

Did you check the pitch on your prop, blade to blade and compare?
(Providing your prop is pitch adjustable)
Fuel Filter OK? Could be partially blocked and when high flow is needed
it can't get to the carbs. How are your EGT's when applying full power?
One step at a time, you'll find it.

I just recently experienced a problem similar to yours with my 912. Apply full
power and
watch the RPM's drop drastically on the ground runup. After checking the fuel supply
and filter
etc. I began to disassemble the Bings. That's when I found a large slit in one
of the rubber
Carb sockets.
Apparently at high RPM's, the slit would open up and two cylinders would go lean.
I didn't
notice the problem on the dash because the EGT probe in on the other two jugs.
Might want to
check your carb sockets. You never know...
Good luck.

Hi Michel,
It's hard to explain "to much" vibration, but if the glareshield (over
the instrument panel) "tends" to vibrate, you have "some" to much
vibration. However, a little vibration at a "specific" RPM is quite
normal, I'll think (the resonant freq. for your glareshield). My old GSC
prop. had some uneven tracking, the reason I swapped to IVO- and may
say, my best investment so far.
The airspeed-indicator itself might be the reason for "fluctuating" or
"some" sticky movement. If you are going to change the airspeed
indicator, it will be wise to make an calibration check. Remember, your
indicator is used for the final "speed" data for your aircraft. If the
indicator is "born" with some error, you may get some surprise with a
new installed. With such calibration data, you can correct to the "real"
airspeed, of course with the aircraft's own static system.
As an example, my airspeed indicator indicated no error around a typical
"Kitfox" stall speed (30-35) miles, however, at the max speed is was way
off. Indicated (IAS) was 98 miles, but the real speed was 86. Yes, I did
the test with a pitot static tester.
For your instrument, we use to say; "the instruments walk" try to tell
you something.
Lubrication inside a instrument is not a good idea, these thing use very
little (and very special) lube. The "jerking" needle, might be- a
"slightly" bent shaft, inside your airspeed-indicator.
But remember, if you plan to change-, find out your old indicators error
and correct for this in your flight manual, if necessary.
Torgeir.

Hi David,
Must say, when I first read through this I was thinking about seizure,
of some kind. However, when you say; put the nose down-, do you really
get full power from that point(?), I.E. can climb as normal with 6200 or
so- RPM?
You said the first (time) change of the needle height corrected the
problem, did you lift the needle (enrich) or ?.
I'll think this is a fuel "starving" problem, and something is getting
worse.
Low nose really increase (gravity) fuel pressure, so ..
I a "past" discussion, someone mentioned that you can fly with just
gravity fuel, but the RPM will be restricted- and high EGT.
Have you checked the "pulse" line between the fuel pump and the engine?
If this one is leaking (small invisible cracks), your fuel pressure is
reduced.
My best guess..
Good luck
Torgeir.
(PS. Don't fly before this thing is fixed..)

Hi Ted,
Thanks.
I've been at this site many times, and learned how to upgrade "some"
type's of the old Bing 54 to the vacuum outlet version. I've found a way
of using the same Principe for manual control of the mixture. Have been
"fiddling" with this for some time.

Kerry, I marked the cowl at the junction and glued the rubber - Neoprene
foam - on the cowl rather on the firewall. seems to work.

Has any one on the list used balsa wood for the intercostals in their tail feathers
?
I was thinking that cut about 3/8 thickness it would be stiff enough , any comments.

The balsa would be great until one person leans on the stab or elevator.
Then, there they go !! Suggesy you dont do it. I used 1/4" birch ply
with some lightening holes drilled thru. They are still there after 13
years.

Have checked your prop pitch. Maybe the engine is loaded too much by
excessive propeller pitch and cannot wind up and develop full power until
you put the nose down and pick up speed.
Just a guess

Subject: Kitfox-List: 582 Power loss
--> Kitfox-List message posted by: "david yeamans" <dafox@ckt.net>
I know this issue is about three weeks old, but my 582 is having that
same kind of power loss, again. (RPM slowing down to 5100 to 5200
on ground roll ) I was wondering after all the suggestions, if it solved
anyones problem ?
I had this problem a year ago december, 2002. My first thought was the
fuel sence it was over 60 days old. I drained both tanks and header tank,
and replaced with fresh fuel, purged the lines, done a fuel flow test, it
tested at 12 gals an hr. fuel pump was working, checked floats in carbs.
OK, installed new plugs, even put in new battery. none of this worked !!
After a suggestion to call an authorized Rotax dealer and explain the
problem. He said the Nut on the Tapered Prop shaft that is connected
in the Gear Box, needs tighten'd. He said he's tighten'd 100's of them,
and no doubt , that is the problem. Took off the gear box, after draining,
went to town to find a big mechanic with a big wrench. He put all he had
on the wrench and felt like it was tight as it could get. ..... Reasembled
everything, went to fly, and the same thing. power loss on ground roll.
called Rotax again, the same guy said I needed a cheater bar and put
more grunt into it. This time the wrench is 3 feet long. reasembled ,went
to fly, and still the same thing, Called the Rotax guy again, and he said
to put a longer cheater bar on the wrench, 4 or 5 feet if necessary. A Pilot
friend of mine who weighs 240 lbs was on the end of this 5 foot wrench
giving it all he had. nothing broke !! I was surprised !!! Reasembled, went
to fly and still the same thing. I didn't call Rotax back. and a funny
thing,
I asked the Rotax dealer and shop mechanic at the time if it could be the
fuel, and he said,no way. Well, to make a long story longer. My 240
lb friend suggested to re set the neddle jet to a different setting, I said
it
won't do any good,after all,I was told from the true source that wasn't the
problem. I moved the Jet one knotch, and the 582 has performed
perfect ever sense................. Until now. I installed new plugs,
changed
the Jet needle setting in the Carbs, from full rich to next to full lean,
and still
nothing helps. What worked before, doesn't work now.
What do I do now ? Help !!!
At 5100 RPM the 582 developes 43.6 HP. Enough to still fly the Kitfox,
which I do. After reaching pattern altitude and level off, I put the nose
down
the engine picks up speed, and from there on the engine performs just fine.
Until the next ground roll. and then the same thing, until I get to pattern
altitude and put the nose down.

Man, can you believe it?
I have all my paperwork done, pre-inspection review by eaa and friends,
taxi testing and electrical tests done and I am ready! Four years and I
(thought) I was ready!
I stopped by the hanger today to make sure every thing is ready for the
FAA inspector......and I find fuel weep leaking around my header tank
full sensor port.......I have tried 3 times to seal that threaded port with
permatex, and two other aviation grade sealants.....nothing works.
I read other earlier last year complaning about the poly tank leaking,
and now I know of what you speak!
I will wait until after the inspection, then pull out that #$#%@#ing
tank and replace it with ??????????????? your suggestions please!
What should I use and how much will it cost guys and gals?
Thanks for being there.

I bolted on an IVO and thought ti go faster I would crank in some pitch.
It flew like &
#$% Low RPM poor power, slow criuse ...
Called IVO, he suggested factory setting first.
I did.
WOW
5,800 static, 6,200 at rotation, 6,400 at 55mph, full power climb
Very happy now works perfectly.
These 2 strokes need RPM and have a tuned exhaust. The must be able to spin
rather freely to come alive.
There maybe be something wrong ....look into this carefully..
Good luck!
