Thanks for this message Nick
The addition of metal fuel tanks will certainly be an advantage for us owners and
pilots in foreign countries where Avgas 100/130 is becoming more and more a
rare commodity, gradually becoming available at the major airports only.
Auto fuel is an option with unleaded 93 or 98 octane fuel available. Fortunately
down-under the prominence of alcohol additive hasn't had the same market penetration
as it has in the US, for a range of reasons, the least of which being
the lower calorific output of alcohol versus mineral fuels. Not to say we haven't
had our share of questionable additives such an benzene and a few others
who's names I struggle with.
Always appreciate your input on these important matters and trust you're back to
health.
Kind regards
Rich Cookson

| Subject: | Unorthodox Tire Balancing |
One of my tires is severely out of balance. I have a Marc Parnes tire balancer,
and it is SUPER sensitive, but this is so out of balance it will rotate on the
wheels bearings!
So in attempting to balance it, I've determined it would take 2.5 ounces on the
rim to bring it into balance it. The wheel is so small compared to the tire
that it takes a lot of weight to fix an imbalance in the tire. (And yes, I've
rotated the tire on the rim to make sure it's really the tire. It is. )
So I started thinking about how it would be so much easier to balance if I could
get the weight further out on the tire instead of inside the rim. Then I saw
that old inner tube laying there...
So my question is this: If I cut a flat section of old tube and laid it inside
the tire, between the tube and tire, does anyone have an opinion on whether or
not that's going to wear a flat spot on the tube?
I've felt the inside of the tire, and it's by no means smooth. It has grooves
and imperfections that feel about the same thickness as the wall of the old tube,
so it would seem to me that it would be fine. Opinions?
If it would work, I could balance it with a fraction of the weight, and I'd never
worry about one of the weights being slung off the rim and going on a wheelpant
eating spree.

Hi Bill,
I think you will be fine with the fix you have described. However, my
question is what brand of tire is that far out of balance? And how many
ply tire is it? Or is it maybe a recap? Of all the aircraft tires I've had
over the past 35 years on six different airplanes I've never had one that
far out of balance.
Blue Skies,
Buz

Bill, I would give it a try. If the tire is new, most places will replace it
no problem if you tell them its that far out of balance.

It's got about 35 hours on it. It required about 1.25 ounce when it was new.
I don't recall landing with the brakes on! :)
There are no flat spots, and insignificant wear, but it isn't perfectly round either.
When I just spin the wheel I can see perhaps 3/32" of out of roundness,
but that doesn't correlate with the heavy side, so I don't think that's the
problem? Brand? I don't even recall, but I'll look next time I'm in the hanger.
I think it's a 6 ply tire.
I like the tires well balanced, which is why I own the balancer. Ditto for prop
balance. Vibration in an airplane is a great thing to minimize.

Well after what Nick said I am back to 100LL. Seems it is not the engine but
the tank that has the problem. Do not need that problem. The answer is the metal
tank which I cannot have with my plane. So 25 hr oil changes will be the
norm on both of my machines.

the problems that I see, I have no experienced here in the USA. I use a 91 octane
no lead, no alcohol gas in my Jabiru. I have only used it for about 6 months.
Main reason is I also have a Rotax in a motor glider and it hates lead,
so it is convenient to fill the tanks at same time. My question is,"if What are
the results in engine life and performance if you can run a non alcohol gas?
With the Rotax it seems to be 50 hr oil changes instead of 25 hrs. It also means
I can go to 2000 hrs TBO if I take care of it and I know of several that
have. Can anyone give your history with the Jabiru in the lighting or any other
aircraft for that matter.
