I know less than nothing about Ezy's, so if the following is
standard procedure for setting up the gear, then just disregard.
The 1st thing that came to mind is instructions for doing weight
& balance on planes with spring gear, like RV's. We're told to
roll the plane up ramps onto the scales (meaning, don't hoist it
up and lower it onto the scales), because lowering it will cause
side-loading of the scales. Friction will keep the gear from
spreading to its natural width as the full weight of the plane
comes down on the gear. An alternative given is to use 'greased
plates'. Two rigid plates with grease between them sitting on each
scale; then the plane can be lowered onto the scales & the
greased plates will slide, allowing the gear to assume its natural
'spread'.
Any chance that the gear wasn't spreading fully when it was being
set up?

You could get the small home depo electronic level (12") and
lay it up on the side of the rim and check your camber. ( or
just guess ) then install a camber shim to set it back at "0" or
-1 deg
( set in at the top)
If you are on the ball, you can set or fix the toe in at the
same time.( add a 2nd shim)
Check with marc or jd to try to find the shims.

Well,
on one hand I am pleased that when I did a quick loop of
the pattern after I got off work this morning (I just
switched to graveyard shift this week so get off work at
0700 hrs) my rotary ran smooth and strong and seemed to be
producing pretty kick ass power.
HOWEVER, when I landed, I had my
starboard tire blow out. Yes, it is quite the attention
getter. I swayed slightly to the right of center of the
runway at LVJ and luckily exited the taxiway closest to my
hangar.
I was able to get it back to the
hangar. No damage to the aircraft this time, not even the
tire rim. But, I noted I had excessive wear on the inside
of the tire.....much more than i would have expected with
only 15 landings and less than seven hours of flight. I
have done extensive taxi testing though (basically having
and expensive go-cart)
I had noted on my conditional
inspection that I had uneven wear but it did not seem that
bad and I pledged to mind it. I concluded that the uneven
wear on the inner tire was due to the gear spread that I
had noticed on my and other canards (my hangar mate has a
long easy and he is always lifting his bird to get the
gear from spreading after taxi).
Velocity is pretty specific on how to
set the camber and recommend you set the camber after
installing the engine and wings, which I did.
When the gear is not spread, the
tires set directly in the center "meat" of the tire.
However, I have now noted...with the consequences, that as
the gear spreads, there is a significant tilt to the inner
edge of the tires thus causing the wear.
The gear bow is provided in the
Velocity kit and it quite sturdy. What am I missing
regarding the bow spread tilting the tire to the inside of
the tire, thus wearing in what would seem a less wear
prone area? I am certain the camber was proper when the
gear is not spreading out. I remember how tedious it was
setting it, lowering the plane, checking, lifting,
setting, lowering, checking repeat a number of times to
ensure the proper set (same goes to the toe-in process),
but it is significant enough from the spread to roll the
tire on the inner edge to cause a problem.
Before I drop a few hundred on new
tire and tube and try to fly again, I would like to figure
out what I need to address. Is it just to re-set the
camber to be on the center meat of the tire when spread
since this seems to be the case when taxiing or is there
something else?
Insight guys???? Discuss.
Thanks,
Chris
