Hi All,
Not strictly Zenith, but amazing just the same: The guys from The Airplane
Factory are flying around the world, and are on their second last leg, from
Rio to Cape Town, they have just taken off, you can follow them with this

Hi Brad,

Do you hold the axle horizontally to spin the wheel?

put a layer of racer tape over the weight as a precaution, but the stick-on
weight glue is really good.

HI Bob,
If I wanted to do that (and I am now considering it) I would take the whole
wheel assembly down to my local tire shop and ask them to balance it. They
have both the tools and weights to do the job and already know how to do it.

My 701 will get a shake at high speeds and will stop as it slows down. I
know that it is the balancing and will take care of it at the next

Hi Bob,
No, I didn't check the balance of the nose wheel.
What I did do was make the mistake of thinking if I kept a low tire pressure
it would cushion the nose and give me softer touch-down bumps.
Unfortunately, the Matco wheel doesn't hold the tire and tube very well
without a reasonably high pressure in the tire. The result was the tire and
tube rotated in the wheel and turned the metal valve stem into a pretzel. I
replaced the tube assembly with one I had laying around the shop and didn't
consider the balancing issue.
I suppose the nose gear vibrations could be a wheel balance issue, but I can
really feel the side to side motion in the rudder pedals when the gear
touches down at relatively high speed. My guess is the direct linkage
between the pedals and the strut really need some sort of shock absorber or
damper in the connection someplace.
I also guess the source of the vibration is a slight misalignment between
the nose wheel and runway at touchdown. There doesn't seem to be any
feature in this design that straightens out the wheel when it is a little
out of alignment. The last plane I flew (a Tecnam Echo Super) had a
trailing link design in the nose gear that naturally wants to go straight.

Hi David,
Yes, I like your description of a clamp.
I wound up taking the lower blocks off and grinding the hole a bit
bigger so the column moves freely. I guess there is still a side load
from the tie rods connected to the rudder pedals. I also have a tight
upper bearing but I don't think that has an impact on rotation. I don't
know how to remove the upper bearing without removing the bungee. I had
no problem installing and removing the bungee before the engine was
installed, but now it looks like a real bear.
I was just out doing some circuits and bumps. I found if I land with
full flaps the nose wheel behaves when it touches down, but if I do a
no-flaps landing it tends to shimmy when it touches down. I wish I know
enough about mechanical design to be able to figure out how to stop the
shimmy at higher speeds.

hours of flying. Yeah, you still have to push a Zenith rudder harder than
you would in a Champ to overcome the initial "centering tendency," but I
have no problems with it going back to center.

Brad, I believe the procedure you described might not work in all cases.
For instance, if you have two identical heavy spots opposed in relation to
the wheel centre, it would still wobble.
I tried to illustrate this in the picture below.
The red marks represent the "heavy spots". As the wheel spins, the
centrifugal force at these spots will try to twist the tire, and it will
wobble - despite the fact that the CG is on the axle.

Carlos -
I see your point, but I not sure that would be a real world problem with the
small diameters and strong sidewalls we are working with. I was giving Paul
a method to use at home as opposed to taking the wheel to a tire shop. A
shop would most likely bubble balance the wheel, which is not going to cure
the problem you describe. Current spin balance machines would not correct
for the problem you are describing either. How would you balance the tire
in your diagram?

Hi Dave,
I don't know for sure, but I think that would not be a problem. The
trim tab size increase is something less than 50 percent. Also, the
elevator authority is a lot higher than the total trim force.
I have taken off without adjusting the trim from full flaps to neutral
with no flaps and the amount of force needed to get the desired pitch
was easy to generate. This might be a direct answer to your question.

Hi guys,
This is a very interesting method to balance the wheel and I'm sure it
would be easy to do. Of course this would be messy since you need to
remove the wheel bearing grease and repack it, but getting full of
grease is not the end of the world.
On the other hand, I never thought my wheel needs balancing. If the
vibration I experience when touching down at higher speed (without
flaps) were from poor wheel balance then I would also experience it when
taking off at even higher speed. I do not.
I still want a way to damp the shimmy I get when landing at higher
speeds with the nose wheel slightly misaligned with the runway.

FWIW. I have 6x600 tires/wheels all around on my XL. When I first flew it in
July 05 I had a bad vibration problem which exhibited itself on lift off, f
rom the nose wheel. I jacked up the nose, and by rotating the tire/wheel the
tire would always go heavy side down. I bought some stick on weights at a l
ocal tire shop and installed them on the wheel's outside inner surface for b
alancing. Could spin the wheel after balance and it would stop at random loc
ations. No more vibes after lift off.

Not depressed much, may 1/8". The point is that if you have no
depression, you my have a bungee that is too strong and you may be
getting some friction at the top of the strut that interferes with the
self centering.
