Jose and Kurt, the bead grip was also my concern since the tyre is not as wide
as the wheel. I called the guy who got and installed the tyres for me and he says
that there is no problem going down from 30 to 20 psi but I should be careful
to go under that.

Kurt and Larry, I don't use powder, I don't mount the tyres myself. Are you crazy?
I would get my hands dirty! :-) Seriously, this was done by the guy (a big
tyres retailer in our town) who found and sold me the tyres. ... talcum, soap,
that's not a man's work, is it? :-)

Would anyone on the list that is parting out a Model 1V have a trim
servo for sale. Just found out that mine has had a spike and needs
replacing.

I had a 196 Garmin that I sent in for repairs. They charged flat fee of
200$ and it came back within 2 weeks.
They told me that they would fix or replace for the flat fee.
Great deal and great service .

I have IQ 3600 by Garmin and sat on it... ops, there went that nice
color screen. Totally my fault and I have had it for 2 years. It was
replaced with a new unit with all updates for 75 bucks, and that
included next day shipping!
I also have a old 195, works perfectly
You get what you pay for. I would buy another Garmin in a heart beat.

I met Gary Walsh yesterday in an airport in Ontario. He had just installed
the MIPPI treadless tires. They look great and are about 21 " tall and 12
" wide. For any that have seen Super Cub Hardcore movies I am sure Gary
will be next to perform some stunts like those . Very impressive looking
and with 912S his take off made GA aircraft there look sick.
Looking forward to seeing some Hardcore Kitfox movies soon Gary .

Michel,
I wonder about tire slip also, but in a different sense. I find it
extremely difficult to break the bead with any tire I have ever put on these
8" original Kitfox rims. I damaged the hub once trying to break the bead
using a tire demounting device.
For breaking the bead, I was advised to place the wheel and tire on the
ground in front of my car tire and then drive over the kitfox tire. I hope
this makes sense. It will break the bead without involving the rim in any
mechanical device. Past experience suggests to me that tire slippage would
be quite unlikely. However, I have heard of it happening to others.

I will share a friends dislike for his engine combination. Series V 'Fox, with
Stratus E81 and IVO Magnum prop (wide chord). With the pitch set to the recommended
static rpm, climb out and cruise were nearly the same, ie 85mph. This phenominon
was induced by a need to significantly reduce power to avoid over reving
in cruise.
After changing to a medium IVO set up he join the ranks of those who are happy.....

Those are the blades I have John.
Trying to get my mind on topic again to think this in
debth. Not always easy these days.
Wider blades grip air, like all WX tires grip the
pavement. Narrow blades more like dragster tires.
You get a better bite with the wider blades from the
start = more static thrust and less slippage. But the
narrow blades come into their own as you speed up and
allow the engine to spool up better from the start.
The wider ones should run more draggy at higher speeds
and, as was said, for descent and landing.
If your tires grip and not slip, you need a lower
gear. If your prop grips from the start, you use less
pitch to keep RPM's up. Less pitch means the wide
cord blades will run out of pitch sooner in cruise.
Fixed pitch would theoritically like the narrow
blades. But if you have a cockpit adjustable prop,
the wider blades might be better?
Less diameter should mean some more slip too. Less
efficiency on the same pitch and rpm, but maybe allows
more HP from the motor..... You'd need to add a
little pitch for the reduced diameter, so it should be
less static thrust and maybe a slight plus in cruise.
I just cant see enough gain from reduced diameter to

Hi Lowell,
I havent tried this, but if you no longer want the
tire, try a vacuum pump on it. Would only apply to a
tubless tire though.
You definately want to press on the tire only and not
damage the rim. It doesnt take much to damage alum
rims.
If you drive over the tire, put some cardboard or
carpet under it to save the rim from scrubbing on the
concrete.
Another try might be a LARGE C clamp placed right at
the bead.
I know of others who have their tires slip too. All I
know were due to underinflation.
Just some ideas. Of course you could try a tire place
or 2 and see if their machine would fit?

I installed a set of the King Fox 21x12x8 tundra tires from supplier in
Michigan. Very pleased so far. Good service. They were only $ 40 each,
and they did not change the appearance/performance of the plane much over
my smaller 20x7x8. Added a lot to the off airport utility. Photo uploaded
in the replacements section of Sportflight. Check them out at if you are
in the market for this kind of product.

Been wondering about that IVO Magnum myself....
Thanks for the info. It might work as a variable
pitch, but obviously is restrictive as a fixed pitch.
Kinda confirms my theory statement of narrow cords
allowing more latitude thru slippage.
Also wondered how the Stratus works compared to the
NSI. Would be interesting to know the +'s and -'s.
Any other Stratus owners here?

Thanks Kurt,
The vacuum pump idea is a good one. I happen to have an industrial strength
vacuum pump under my work bench. I will use it next tire change and report
the results.
I did use a piece of carpet to protect the rim - thanks for the warning to
others.

The differential pressure test is probably not a good idea for a 2 cycle engine.
It doesn't take a lot of pressure in the crankcase to blow out the crankshaft
seals.

Somewhat the same with me John. On grass it takes a
bit to move. If I use my normal takeoff power, I
probably use 500 feet or 8 seconds to lift off of
grass. (Timed from movie camera footage of my
takeoffs from the cockpit.)
If I use full power, which I can get with the cockpit
adjustable prop, that last 300 RPM really peaks the
turbo and you can feel the change. About equal to
going from 2 people to solo. It is on the top end of
speed where I seem to run out with this prop. More HP
isnt going to more speed.
On landing I am still trying to find a reliable way to
set pitch for less float and yet have go-around power
available. I can either float, or make a bunch of
noise as I land when I wanted to go. So far, I try to
set 2000 rpm at closed throttle and accept that, but I
do float. Slips are very useful.

Well, first keep the fun part going John!
To start with, I built in a fairing to the bottom of
the verticle stab so that the fabric does not make
that hard break to the horizontal stab enclosure. I
also added foam into the gap between the inner ribs of
the horizontal stab and the enclosure sheet metal so
that the gap was zero with full nose up trim and less
a gap for the rest of the travel.
Those were the only drag reductions I built in. Cant
tell you if they helped much or not, since I have no
comparison. Filling the Horizontal inner gap should
have helped with elevator effectiveness too, but I
don't know for sure.
I added a scoop to the radiator and gained about 9
mph. Less in hot temps with the exhaust door open.
Took it off and added wing strut fairings and gained
an average 10.5 mph. They do not add up to 20 total,
but maybe a 16 mph gain together. I can't remember my
top level speed right now, but it was nice to see.
Still some to go.
Michel and a French friend of his did extensive work
on the wing strut fairing design and it payed off.
Dont let Michel get away with playing dumb. ;-)
Wheel fairings, wing strut end fairings, top and
bottom, gas cap fairings, H. tail strut fairings, jury
strut fairings, other things to go. I'll try to
measure any improvements, if I can, for each.
That makes twice that I had to learn, then relearn not
to float. Releasing that drag made a very noticable
change in the pattern requirements. And if you want
to float lazily along at 65 knots or 75 mph, my Fox is
now a very quiet and fuel efficient plane. But more
to go. It is still working too hard past 85 knots
(100 mph) for me.

Friends, my Kitfox is flying much too fast! I don't get a chance to
look at the scenery. Luckily, I have a very small video camera that
allows me to review the scenery afterward, in the comfort of my home,
by the fireplace with a good brandy. Now, look what I found (I grabbed
a frame from the video): Casper the friendly ghost!
I swear i didn't manipulate the photo, there are two tiny islands on
that lake. Funny, isn't it?

This is why I don't want to do it myself, Lowell. I take the wheels to
the workshop that does it professionally. They use a machine that turns
around the tyre making a "poof!" sound. Cool stuff!
Gary, the King Fox tyres are very good looking but, because of my wheel
penetration skis, I can't use them without major modifications to the
skis. Hence my choice for some slightly smaller tyres.
Cheers,

Marcos,
Good question and I would say that if you know your mags ground out then
with both mags off you should have no spark to damage the Ducati

Kurt, With an inflight adustable, do you not set full fine (or t/off
setting) on final for go around?
On t/o with the prop setting I have now, the diff between 4300 and 4700 is
like day and night but as you say, it's the turbo boost at the latter
setting that make the diff. I still need to coursen up a bit as full noise
is still over 5000. If only I could get time to play...John

Yep, I did this too, added a profiled leading edge to start of the vert stab
to split the flow. Guess it all helps for as I've said, up to 100kts is
relatively easy. Hopefully after increasing the prop pitch and get the boost
up a bit at lower RPM I might get a wee bit more..John

| Subject: | Re: 582 - compression test |
I have made about 20 CDI's in my time so I can enlighten you as to what
goes on. If you don't have that spark gap when you create a spark you
get a very high voltage build up and the solid state components in the
modules might well fail. Then again they may not but it's certainly not
a good idea to temp fate. When an ignition module fires it builds up
voltage until it is high enough to jump the plug gap and then the energy
is dissipated. With no plug gap to jump the voltage keeps building to a
very high figure. Shorting the plug lead to ground [ the cylinder head
or whatever ] will also stop the build up but may overload the module.
The right idea is to have the plug lead connected to the plug and the
body of the plug grounded. A plug usually fires around 25,000 volts but
if the lead is left floating in mid air the voltage may well go to
100,000 with CDI. [ Capacitor Discharge Ignition ]
