Weird Michel,
No doubt an Norwegian flat spot. ;-)
I also had to do this 180 degree dance in my old
hangar around another plane, not on a rail. I tried
to make sure to roll the plane a little each time I
turned it, to save the tire.
Is there only one such spot per tire?
Do you spin it directly on the rail without rolling
movement for each tire in turn sometime during your
parking? Or is only one tire turned on the rail?
Does it thump while taxiing, or is it no problem other
than the wear look?
As Rex says, mark the flat spots somehow and see when
you get a new one. Maybe the cause can be narrowed
down from that.
To me, it looks like the spots are larger toward the
outside of the tire. I can't see a way for this place
to be on the bottom with your bungy mounts so close to
the belly even with the plane's weight on the gear.
They can't pull up and bring the gear in much more in
flight to cause that spot on touchdown, or can they?
You need to lift it off the gear to see if those
outside spots are straight down in flight. Make sure
your wheels spin freely then as well. If these spots
are at the bottom in flight, it must have to do with
landing and not action after the gear spreads???
More data needed....

Revenge? From a sweet, innocent and candid guy like me? Never! :-)
As you know, the knot is the ancien method of streaming a line with knots, overboard,
while taking time with a timeglass. Today, it is standardize as one nautical
mile per hour. So the question is: Why the nautical mile? Well, as seafarers
still use Mercator maps, you can easily measure a distance using the minutes
of latitude as a scale. And for as long as we divide the circle in 360 degrees,
the nautical mile makes sense. Even in the air.

Noooo, is that true? That's funny, Kurt, because when I learnt to read a metar,
I got easily the mnemonics: RA is rain, etc. But when mist was written BR, it
didn't make sense in English, so I memorized it, using the French word: Bruine.
I thought it was just a coincidence, now you confirm that it is, indeed, the
origin of the two-letters code. Amazing!

Michel

Hello Kurt and Rex,
> From: kurt schrader [smokey_bear_40220@yahoo.com]
> Is there only one such spot per tire?
No, there are about 3 or 4 on each tyre, some more visible than others. I don't
pivot the plane with the tyres right above the rail, of course. But, as it passes
the rail, the plane is not moving straight, which could explain why the the
depressions are sligthly diagonals. No, Kurt, no thump when taxiing, it's a
smooth ride. The tyres are inflated to 11 psi.
I have never had that before. Those are new tyres from last summer. The depressions
only came this winter. No more are coming now that the temperature is higher.
In my opinion, there can be only two reasons:
1) The rail, as I suspect it most. But then, why didn't it happen with the old
tyres I had the two last winters? They were of the same make, only that those
new ones are not tubless, as the old ones.
2) The skis. It could be that, when I land with the penetration skis, the tyres
expand so much that it locks itself on the edge of the skis. But then, I should
see wear on the skis, which I don't. And I should probably feel it when landing,
like, nose down, because it would work as brakes, which I didn't experienced,
thanks god!
Here an interesting note about the wheel penetration skis: It makes landing a taildragger
much easier because the tiny wheels at the end of the skis touch the
ground first. Since they are behind the CoG it induced a slight nose down moment.
Which is just the opposite of a two wheels landing which induces a nose
up moment, increases AoA, bounce, and ... you know. Of course, the skis are mounted
with bungees, in the front and the aft end effect is only very light because
the bungees give easily way to a nose up attitude but ... it helps!
Last: Sorry guys if I write "tyres" and not "tires." It is not that I am a British
snob, it is simply that I have to put my speller to US or British English,
and ... I choose the latter because .... er, hum .... UK is closer to Norway,
than the US! :-)
Cheers,
Michel

Is it possible that you have a "tight" spot in the rotation of the wheels so that
it comes to a stop at the same position and touches down at the same point
of the tire on each landing?

Well, manufacturers can change something in a product at any time which
could result in a difference between sets of tires, not to mention a
difference verses tubeless style tires.
Rex
No problem about British spellings from me. :-) Not to start another
off topic, but I often wonder how certain American English spellings and
pronunciations were influenced for specific words. Like "Organize" where
we use a z instead of an s. Certain pronunciations like "Schedule". I
think I could guess most reasons in a general way, but the entomology is
interesting. Thanks Kurt for the BR explanation.

Michel,
I really can't see the rail doing that if the tire is
allowed to rotate as you turn the plane. Even doing a
no tire rotation turn with your plane might scrub the
tire, but not make a flat spot. The rubber would have
to be very soft to scrub it flat in that way.
Cold weather seems to be the clue here.
Do the flat spots disappear and leave just scrub marks
when the tire gets warm?
Is it possible that you have ice buildup between the
tire and the ski and it scrubs the tire and rips the
ice off on landing without touching the ski? It could
ice up on the side as well as on the tread.
Remember the ski acts like a carpenter's plane if it
touches the tire. You could be shaving the tire
against the ski without seeing harm on the ski. Make
sure to round those edges off and maybe open the gap
up 2 mm more.
Those are either flat spots from cold tires holding
shape, too soft rubber, or a significant scrubbing
that doesn't occur every time. Otherwise you would
have a flat spot for every flight/parking event.
You need to look closely at those marks and see if
there are any little cuts only in them. Straight
cuts? Rotational cuts? No little cuts? BS cuts from
ahhhh Barely Skiing? :-)

Kurt is right, the tire needs to be looked at very closely for evidence
of what may be the cause. My suggestion was only regarding a cold
temperature cause. I would probably remove a tire and inspect it inside
also.

problem, but my Kitfox is in Colorado)

If it is the gauge that reads to 10,000 RPM with the orange set pointer and
the red RPM pointer --- then this gauge is the one designed for the 912. It
is the gauge that came with my engine, direct from the Canadian distributor.

I have someone interested in the VDO RPM gages but I don't know if they
work with a Rotax 912 ignition system. Can anyone advise?

I was hoping they would, but they are still there and the OAT has been
up to 20 C this week-end. But there are no scrub marks, no little cuts,
nothing, just depressions on the surface of the tyre. Really weird!
Now, if it is not the rail, it must be the skis. But then, I have made
them with some clearance, of course. Ice could build up but it was too
cold when I flew to have ice, only dry snow. It could be that the tyre
changes shape as it rotates, getting wider in the middle with speed.
But if that happens, when is it most likely to happen? Under landing, I
would think, right? But then, if the tyre was expanding and locked
itself on the edge of the skis, I would feel it like a dangerous
braking and nose down, wouldn't I? I didn't notice anything when
landing. Could it be that it happens when taking off, when the trust of
the engine is such as a brake effect won't be felt?
In any case, I don't like it much and I will change the tyres. I could
take them to a shop and ask what they think it is, but in any case, the
answer will be: Change your tyres! Which I will, when I find what I
want. Maybe more ply. Maybe with grooves. But I have problems to find
the right dimensions because any other dimensions would mean that I'll
have to modify the skis too. Hum, I need a cold beer right now! :-)
Thanks for your help, guys!
Cheers,
Michel

Yes, yes, yes! I love "off-topics," that's the only thing I am good at,
Rex! :-)
The reason some words are written differently in UK and US English is
that there wasn't a proper English dictionary for a long time. The
first language to come with a dictionary was Castilian (Spanish) then,
French. From the 17th century the Academie de la Langue francaise made
sure there was only one way to write French. And that's the reason it
became the diplomatic language, spoken by the Russian, Dutch, and many
other aristocrats in Europe and beyond. It was the only language one
could learn from a dictionary and a grammar.
And that is the reason so many French words made their way in the
English language, especially within law and trade, where words needed
to be precise. Then, while the Brits kept more closely the French
writing, the American early settlers used the words more like they are
pronounced. A good example is manoeuvre and manover, the former being
written as the French word it comes from, la manoeuvre, which literally
means: hand-work. As a Floridian, do you speak some Spanish, Rex?
Manover = maniobra! Same Latin root.
Cheers,
Michel

Michel I forgot if you had tubes or not. Possibly tubes folded inside the
tire making an uneven centrifical force applied to tire at speed? The edges
surely hit first on landing followed toward the middle as the gear spreads.
I think we have worn your tires out ourselves. Ron NB Or

Been trying not to go there Michel, but....
Have you seen any crop circles lately? ;-)
Actually, people don't realize how much a tire flexes
in use. If you look at how much it squashes down when
the plane is loaded, well it has to bounce back from
that flex as the tire rotates and the tire elongates a
bit. Many people with wheelpants experience damage to
the pants from tires hitting them as the tires flex on
landing, either the sides or tread. The clearance may
look fine, but tires do bounce.
Again you need to look closely at the flat parts to
see if you can detect damage. Otherwise don't install
the new tires until you have the skis off for the
summer. Then see if the pattern shows up again only
after the skis are added.
Looking inside as was already suggested, is a good
idea too. I had a tire on my van where the tread
looked fine, but seperated internally and got a big
flat spot. It made the van wobble like a drunk!
Sounds like this is not a dangerous thing but a tire
wear economic problem for now. Wierd or not, it is
nice to have these kind of problems to enjoy solving
instead of the other kind.

Nope...it's what Aircraft Spruce seems to tag everything that they deem
to be something that we builders ought to buy for our homebuilts. In
this case, the homebuilders tailwheel is a gem.
It's built by a company out in your neck of the woods,
Duane...California...can't recall the name of the outfit, though. The
name is on a bill in my pile of papers, and you've SEEN my pile of
papers!

--> Kitfox-List message posted by: "Randy Daughenbaugh" <rjdaugh@rapidnet.com>
I have been seeing discussion of thrust lately and I think it is nearly
irrelevant.
I have a PowerFin three blade prop on a 912S Series 5/7. When I first set
it up, static RPM was 5800 RPM. And MAN DID IT HAVE THRUST! The
acceleration would make your head snap back as you pushed the throttle in.
Well, it came time for first flight, and boy did it get off the ground fast!
I don't have good numbers, but I am guessing about 150 feet ground roll.
BUT (you had to know that was coming), it would only fly about 65 - 70 mph
without over-reving the engine.
So I put in more pitch on the prop. Got up to 85 mph. But lower static
rpm, less thrust and acceleration, longer ground roll. Added more pitch -
95 mph, and less thrust. More pitch - WOT about 108 mph - cruise at 5500
rpm about 96 mph - static rpm about 4900 rpm. But now ground roll on take
off approaching 500 ft. Spam can territory!
PowerFin said they would shorten the prop 1" each blade. I finally took
them up on it, but it was a tough decision for me.... When I put it back on
the plane, I added a degree and a quarter more pitch. Now I cruise at 106
mph AND off the ground much quicker - maybe 275' solo.
In short, if you want more thrust, all you have to do is sacrifice top
speed. Therefore, thrust is irrelevant.
Indeed, it is more complicated than that. An "efficient" prop slips enough
on take off to get the rpm up so that you can use most of your horse power
to get off the ground, but still has enough pitch so that you can get a
decent top speed. My plane is "over prop'ed" with the three blade PowerFin.
I am saving my nickels for the Sensinich ground adjustable two blade.
I would have written this earlier but was in Montana visiting my new
grandson and didn't have my flame suit with me.

Randy,
No flames here. I have two friends that went to the PowerFin. They had the
exact issues you had and eventually went to the shortened blades. They got
the improvements you did. One is now with the Warp and doesn't know if he
likes it. I think the other still has the Powerfin. They'll both be at the
Cameron Park fly-in.
I guess that is what the poor man's dyno was all about - finding the HP at
the prop.
