Ron:
Thanks for taking the time to write.
What model of RV?
How bad was the shimmy before?
How much lead did you use?
What axis did you balance about (the landing gear axial?)
I was under the impression this would help, as you where obviously. At worst I
was under the impression the effect would be no change, not WORST!
I was thinking of doing wheel pant balancing out of the box, before first flight,
but now I think i'll wait.
Any other advice or thoughts on why this made your shimmy worst? Did you do additional
flight and adjust air pressure?
Thanks G

Hi Trevor
I had this exact problem. The issue did not turn out to be a mis-punched rib
but rather a mis-bend elevator skin. However, in my situation, both ribs fit
one side and neither fit the other. Vans replaced the skin for me without
any hassle at all. If I were you, and considering the minimal cost, buy a
replacement rib and see what happens.

I did leave some essential info out of my first post.
RV-6A. Old wheel pants
Before all I really had was minor to moderate shimmy of the nosegear.
I could count on it at around 18 knots while taxiing.
I balanced on a rod about the landing gear axis. Obviously while off
the gear. Seems like I used around 320 grams just to make it slightly
nose heavy.
I have essentially eliminated the main gear problem but still need to
remove more
lead. I have tried lowering the nose tire pressure to as low as 16 psi with no
improvement and making the nut tighter (below the belleville washers).
I sure would like to find the magic combination that eliminated the nose gear
shimmy.

Saturday was the annual Lamar CO (KLAA) breakfast/lunch fly-in.
Breakfast and lunch is free to pilots and crew (Hear that EAA?)
Breakfast included pancakes, sausage and scrambled eggs.
It was wonderful. Perhaps being free makes it taste just a little
bit better.
Two of the three RVs from Meadow Lake then went to La Junta
(KLHX) for $2.80 100LL. it is $3.70 to 3.90 at 00V. Today I flew
to KLHX to make a produce run at Van Hooks then fill up on that
100LL. Then on to Pueblo (KPUB) for two VOR approaches.
Pueblo controllers are very nice and make practice approaches
a pleasure.
This instrument training is adding many new skills that will make
flying better when I can get up or down through a benign cloud
layer instead of cancelling trips like I do now.
Another wonderful day of flying with 100 mile visibility. Some light
turbulence from the winds over the mountains but that will end by
Tuesday.
Now over to change the oil and grind out more wheel pant lead shot.

Ron,
If you have been following the recent RV-List you can get a
special mount for your unit from Air Gizmos http://www.airgizmos.com for
about $100. I understand Vans sells them as well.
I have one mounted in my -4 to hold a 296. I have uploaded a
photo so you can see. Unfortunately the picture does not show how far it
sinks the unit into the panel but if I had to estimate it is about 60%.
One nice thing about these is that you can remove the GPS if you want to
take home, update or service the unit vs. a custom mount behind the
panel that will make it more difficult to remove.

320 grams seems like an awful lot on a nosegear. I used about half a
pound (roughly 227G) in my main gear fairings, which are quite a bit
bigger than the nosewhee l fairings. You said you made it slightly nose
heavy on purpose- why? The idea is to get it to balance as close as
possible. The fact that you improved things by removing lead seems to
indicate that you used too much.

I've not been following this thread closely ..... so bear with me.
1. the problem is with the nose gear.
2. It shimmy's (at least I think that's what was said!!!)
3. Balancing didn't help.
Now, here's where I have no experience with RV nosegears ...... but I do
with Grummans.
The cure for shimmy in the Grumman nosegear is to put a spring scale on
the axle and pull sideways, adjusting the nosegear swivel nut until the
belleville washers produce a drag of 24 Lbs. Sometimes it takes more.
As for balancing the nosegear, the pivot point is only a few inches aft
of the front of the wheel pant, and to balance the nosewheel would take
significant weight on that short moment to counteract the longer and
heavier moment of the tire. Just an observation. I don't think
balancing the nosegear/pant is the answer ...... the answer lies in the
correct assembly of belleville washers and the tightness of the nut.
Linn ...... learning a lot here!!!

New nose gear rod, or old?
Running balanced pants here with no issues; minor shimmy on asphalt during high-speed
rollout, resolves with deceleration or moderate brake application. No
stiffeners. Tire pressure typically 28 in mains, 24 in nosewheel.
Mostly grass strip ops, where shimmy goes unnoticed anyhow, among the divots and
moguls :-)

You make a good point about the geometry of the nosegear. I have a TD
and never had to bother with balancing a nosegear. I think there are
two different forces at work on the nose and main gear causing them to
shimmy. The main gear are more prone to side-to-side shimmy because of
the geometry of the gear leg, vs. the nosegear. I do stand by the value
of balancing the main gear pants, but as with anything else in this
business, YMMV.
For those who don't know about balancing wheel pants, a picture or two
is worth a thousand words.

Ron, have you had someone outside the plane watch as you come taxiing by
with shimmy present? I've watched nosegears on RV's do an interesting
pitching "shimmy". I don't know why. Back and forth (castering) shimmy is
a whole different thing, which should be eliminated by increasing the break
out force or playing with air pressure. Keep in mind that it is important
to keep the nosegear tire inflated as much as possible, because they are
notorious for chewing up innertubes on the sidewall. I make sure that the
edge of the tread is a little off the floor, maybe 35 psi?
I've never had nosewheel shimmy, but I do have a main gear fore/aft
oscillation that an outside observer noted. In my case, I never had it with
the old crappy tires that came with the kit, but when I switched to Michelin
I had this very noticable fore/aft movement at 23 knots. I balanced the
main gear fairings also by putting lead in them, as regardless of whether or
not it eliminates "shimmy", it should reduce pitching forces on the fairings
when taxiing.

The 320 grams was in the mains. The nose gear was much less.
Perhaps I misread the balancing goal.

Visibility is not as good as some of the aviation handhelds, but that is its
only draw-back. Still usable in any amount of daylight, I really love the
following features:
Easy to upgrade software and database
Flight planning where ever you are - I use my iPaq at work all the time
You already know how to use it.
Versatile GPS options
If you are considering iPaq also look into MountainScope software:

The 3-d terrain is simply unsurpassed and most other features are about
like anywhere map. Same Price.

Bill,
I've had a love/hate relationship with AnywhereMap for the 5 years I've
flown with it. One of the reasons I got it was that I carried an Ipaq
for business and that made it a tremendous bang for the buck to get a
color moving map - at that time, 2001. If you don't already have a PDA,
today's value comparison is a lot different. You've got lots of very
good choices. I spent a lot of time at the 2004 SnF looking for an
alternative since my Ipaq was dying. I elected to upgrade my Ipaq to a
4705 and stay with AWM because it was a dirt cheap choice (aside from
the Ipaq which I need anyway.) It cost $20 to get a new connector and
yoke mount plate and a little time to solder 6 tiny wires. The features
that keep me with them were: the larger much better display of the
HP4705, the AWM database contains private airports which the Jepp based
products do not and AWM displays TFRs and provides hourly updates that
can be downloaded. It's got all the spiffy features of most moving maps
but those couple were distinctive and a plus for me. But that was 2004.
Now the downside and why I will very probably replace it in the next
couple months. No particular order other than the first one.
1) The database, in particular Class B&C boundaries, is WRONG. Well not
everything but there are known errors that could get you busted. When
Houston IAH added a new runway the Class B was changed to add an
East-West corridor with a lowered floor. AWM did not incorporate the
change until about 6 months after it was effective. When I complained, I
was told that their database could not handle the complexity and
besides, AnywhereMap SHOULD NOT BE USED FOR NAVIGATION! Huh??? About a
year ago, I noticed a difference in the corridor boundary between AWM
and the Jepp database in my GX-60. Apparently the FAA made an in-stream
correction to the boundary (moved it 2-3 miles north.) Jepp got it, AWM
did not. When I told AWM about it they said they used gummint data and
couldn't change it and besides, AnywhereMap SHOULD NOT BE USED FOR
NAVIGATION! A few weeks ago I screwed up and was looking at AWM on my
yoke (instead of the GX in the panel) during my climb out. The
controller caught me clipping the floor but was cool and just gave me
the altimeter setting. I thanked him as I pushed over. I sent another
note to ControlVision about it but got no reply. I have heard from other
AWM users that other SUA errors exist including wrong altitudes. It is
also rumored that CV purges their forums of negative comments.
2) The Ipaq connector and AWM's mounting method is a weak point in the
system. The serial connector on my old Ipaq failed (so it wouldn't
charge in my desktop cradle) in part because of the AWM connector/yoke
mount plate stressing it. The 4705 version is much better but it's still
a weak point.
3) It is not realistic to operate off the internal battery. I started
with a CF card GPS and battery life was extremely short. The CF GPS was
also poor at capturing satellites and I eventually switched to the
combined GPS35, cig lighter, serial cable bundle. Performance is good
but there is no battery only option.
4) You can strangle yourself with cables. The cable I've got now has one
cable from the yoke to the cig lighter and one from there to the mouse
on the glareshield. I just slide the Ipaq into the yoke plate when I get
in. The connections have evolved and it's way better than what I started
with. A battery Bluetooth GPS might be even cleaner but I've heard of
some connection reliability issues with Bluetooth.
5) The Ipaq is susceptible to cockpit heat. I've had it overheat when I
left it on the yoke during lunch - with the canopy open, the yoke shaded
and only ~95deg. Once I had to do a hardware reset to get it back. Other
times the display started functioning when I got it cooled down. The
Ipaq was designed for office use so I suspect the dedicated units are
more tolerant of heat.
6) I had a bad experience with their PocketPlates product. I bought it
when it first came out and fooled with it until my subscription ran out.
It never really worked. They changed formats multiple times, never
delivered geosync'd plates, you couldn't run it with AWM and their
update process was fatally flawed. I basically bought into vaporware -
my fault, I'm a software developer and should have known better.
7) I'm not real comfortable with the quality of their software
development. Too many quirks, flaws, architecture issues and rookie
mistakes to believe they're pros. Like the latest major release, 1.7,
that corrupted all your user waypoints when you upgraded. Oops... Also,
on 300nm legs or more I can see a significant difference in the great
circle route plot between my GX-60 and AWM (several miles apart) - which
would you bet is right?
8) Portability is a problem with my setup. Now that I've got everything
routed and secured I can't really move it to another plane. When I was
doing my IFR training in a rental I carried it but never used it. On the
long cross-country after things settled down my instructor pulled his
Garmin from its bag, turned it on and threw it on the glareshield. It
would have taken me 10 minutes to sort mine out so I just forgot about
it.
9) For auto use, I'd have to buy a street mapping application and then
worry about how to mount it and get the GPS antenna positioned - i.e.
see all the above.
With all that said, I've finally had enough. I blown a lot of money and
way too much time on Control Vision and AWM to still be left with a
kludgey system. It was great in 2001 but it's time has passed. Now that
I've seen the Garmin 396, I'm trying hard (well, maybe not that hard) to
talk myself out of buying one. Then I can get a phone with a PDA and
I'll have one less thing to carry around. If you can do without the XM
there are a lot of good deals out there, including NOS 295's. Good
hunting.

Yesterday, I saw a very nice RV-6A with a red, white, and blue paint scheme
land. He aero-braked for a long way, probably until the elevator didn't have
enough authority to hold the nose off. Once the nosewheel was on the ground,
the pilot maintained full up elevator. In other words, the pilot was doing
everything "right". Despite that, as soon as the nosewheel touched, the
nose gear fairing (and presumably the everything else up there) began a
noticable shimmy in the up and down (or fore and aft) plane. The amplitude
wasn't large, but there was definitely a shimmy. It ended about the time he
was at walking speed. My experience with the runway at Lebanon is that it is
in great shape - so I don't think the runway surface was the problem.
I wonder if this fore/aft shimmy has any relationship with the nose gear
failures that have occurred with more than a few -A models...

Somewhere back in the archives is probably my comments on AWM which I tried
in good faith.
Suffice it to say, I agree with Greg. I did not find it to be reliable or
accurate.

| Subject: | Open House at Steinair this Sunday |
--> RV-List message posted by: Tim Olson <Tim@MyRV10.com>
To any of you that are not too far from the Minneapolis/St. Paul area:
SteinAir is having an open house this Sunday. They just moved into
a new 3500 Sq.Ft. facility in Farmington, MN, and they want to see
how many people it can hold. (My personal bet is no more than 1650 ;) )
There will be a Chelton Factory Representative attending and giving
a detailed overview of the Chelton EFIS system, along with Q&A for
users or prospective users. (I believe there may also be some promos
ending after the open house...so you may want to jump on them)
TruTrak Flight systems General Manager Andrew Barker is also attending
to discuss TruTrak autopilots and new/upcoming items.
They'll also be having *FREE* food, which is always a plus.
For the full details, go to: http://www.steinair.com
The open house is located at their new facility, which is located at:
21170 Eaton Ave,
Suite C
Farmington, MN 55024
Located just off highway 50 and Pilot Knob Rd about 3 minutes from
Lakeville Airport (LVN).
The open house will run from 10:00am - 5:00pm
with the free brats/dogs around noon and other refreshments all day.
Those wishing to fly into LVN may do so, and free transportation will
be provided from the airport to their facility.

My two Cents worth
Nose wheel shimmy is sometimes by caused by opposing steering geometry.
With the aircraft loaded as it would be when shimmying, on a level parking
ramp the nose wheel must have zero camber or it will try to turn into the
camber. At a point the caster will overcome it and vigorously correct even
to the point of over shooting. The cycle will start all over again and the
shimmy has begun. Camber must be zero as measured at the steering axis and
the wheel.
The caster must not be tipped aft at the top (positive) or it will over
shoot center steer and rake will oppose it. Rake is the distance between the
steering axis and the center of the wheel. Caster is the fore and aft angle
of the steering axis from plum.
Good things are zero camber, zero caster, slight negative caster is best
(steering axis tipped forward), 22 lbs of preload, and 28 psi air presure in
the tire.
Bad things are no preload on the steering axis, so do what you got to do
to get it, Positive caster (bent or settled gear, loose in the engine mount
and etc), Other than zero camber (bent or settled gear, improperly aligned
or loose in the engine mount, wheel fork axel holes and steering axis not
90* to each other and etc). look for combinations.
I don't think balancing the nose wheel pant matters one way or the other
but main wheel pants balance is a must.
Hope some of this helps

This type vibration is a sympathetic and relies on a seperate viabration
to excite it. Steering preload on a properly mounted gear leg will eliminate
it. I don't know the nature of the failures in question but enough mass is
involved to propigate a fatigue crack that could lead to instantanious
failure in the leg or the mount if not properly maintained.
