Long EZ
by Budd Davisson, courtesy of

What, you may ask, is a
Long EZ? It is not a hold
over from an old John
Wayne dialogue ('Okay,
pilgrim, jest get a Long
EZ"). Nor does it refer to
a very "friendly" tall
girl (the rumours that all
Rutan designs have sexual
beginnings are false,
although names like
VariEze and Quickie could
start people talking).
What the Long EZ is, is
another new Rutan exercise
in foam and fibreglass
with a Lycorning mixed in
for flavour.
But the
Long EZ is not without its
shortcomings, the most
serious of which is that
it looks like its
fore-bearer, the VariEze.
It's shaped almost exactly
like a VariEze. Its bones
use the same foam and
fibreglass sandwich
technique that have become
a Rutan trade-mark and the
prototype is painted the
same as the dozens (soon
to be hundreds) of
VariEzes batting about the
sky. The Long EZ probably
even tastes like a VariEze.
But, folks, I'm here to
tell that it is in no way,
shape or foam----er form-a
VariEze. Once you've taken
it around the patch, you
come down with a messsage
literally tattooed on your
brain cells, "This is sure
as hell no VariEze."
Is the
Long EZ better than that
backward foam-built that
made Rutan a super-star in
the homebuilding world?
You'd better believe it
is! It's just a shame that
it looks so much like a
VariEze.
The
reasons for designing a
new airplane in the face
of the phenomenal success
of the VariEze were many.
The VariEze was designed
to use the small
Continentals, from 65 hp
(never saw one built), to
the 100 hp 0-200 and
absolutely demanded that
weight be kept to a
minimum. It seldom was. As
soon as you give a man a
two-place, 180 mph
travelling machine, he
needs a radio, then a
gyro, then a DME, then an
electrical system and so
forth, until the machine
is carrying around 200
pounds of undesigned-for
garbage. The take-off and
landing performance
quickly began to resemble
that of a hocky puck.
Then,
the 0-200 was discontinued
and the".. . easily and
economically available
0-200 . . ." suddenly
became worth it's weight
in damned near anything.
Also, as more and more
people began flying
VariEzes, it became
apparent that Burt's taste
in airplanes may or may
not match everybody
else's. For one thing,
many pilots complained
about the VariEze's
foxhole visibility on
landing and takeoff. Also,
the stick forces were too
light for many drivers,
especially at low speeds,
and it was very possible
to make a few minor
mistakes in building the
canard that resulted in
stick forces approaching
zero when in approach
mode. And the ai-plane
didn't like grass fields.
As a matter of fact, it
even hated rough concrete.
Then, Rutan himself found
that his "unspinnable"
design could, in certain
unusual combinations of
CG, weight and speeds be
forced to depart into a
spin.
None of
this is nearly enough to
condemn an airplane, in
fact, many designs that
are now flying make the
Eze's list of minor
transgressions sound like
favourable comments, But,
Rutan wasn't satisfied
because some of his
customers weren't totally
satisfied. So, a new
machine was designed.
The
aims of the new machine
were simple: Eliminate all
the problems of the
VariEze and incorporate
the more available 0-235,
108/115 horse Lycoming and
an electrical system. The
0-235 Lycoming is not a
light engine, and since
long range fuel capacity
was another design
criteria, the new airplane
was going to have to be
much larger than the
previous one. The gross
wing area, canard
included, would be
ninety-four square feet
against sixty-six for the
VariEze.
The
final (more or less)
version of the Long EZ
flew in November of 1977
and Rutan immediately
launched into an
aggressive, but low buck
promotion campaign. He had
to. When he originally
announced that he was
designing a new airplane,
sales for VariEze plans
dropped to zilch and his
cash flow followed. Still,
he preferred to let the
Long E'Z speak for itself.
So, rather than dropping
big bucks on lavish
advertising, he put the
Long EZ to work proving
itself. First on the list
of things to do was the
establishing of a long
distance record for its
class. And what a record!
Brother Dick Rutan saddled
up with an auxiliary fuel
tank in the back seat and
droned back and forth over
an officially measured
course until he had flown
4,800 statute mites in
thirty-three and a half
hours. One of the deciding
factors to end at 4,800
miles was that after so
many hours without sleep,
Dick was beginning to
hallucinate. If he had
been willing to borrow a
couple of greenies from a
trucker, he could have
added a pretty good chunk
to the distance. Now,
here's an airplane that
can outlast any pilot.
His
second method of telling
the Long EZ story to the
world was to make certain
brother flick showed up at
any fly-in where more than
three airplanes were in
attendance. His route of
flight was always the same
nonstop. He even planned
far enough ahead that his
nonstop California to
Oshkosh jaunt had him
arriving during the
Airshow
Then,
Dick came up with an
airshow routine for the
Long EZ. It didn't cause
Pitts pilots to drop their
gum, but it definitely
showed the Long EZ's
ability to cavort. Besides
the normal loop-and-roll
stuff, Dick does a
power-off, three-turn,
descending spiral that
starts at maybe 300 feet
and finishes in a landing.
It may not sound like
much, but until you see
him start those turns at
that low an altitude, you
won't believe how clean an
airplane can be.
Since
the VariEze had gained a
reputation as being a
little on the toasty side
for the average pilot,
Rutan began strapping
everybody in sight into
the Long EZ so they could
see the difference. When I
flew the airplane at
Oshkosh in August, I was
number thirty-three to
check out in it and the
number probably broke
forty before the end of
the week. The really
important (and impressive)
part of the Long EZ guest
book is that it includes
signatures from a lot of
folks who hardly qualify
as hot rock pilots. Like
Ms. Pat Storch, for
instance, a twenty-four
hour student pilot who
soloed it with only six
landings and one hour of
dual, and Sally Melvill,
Rutan's office manager,
who had only 100 hours
under her belt before she
hopped in it and
disappeared.
I came
to fly the LongEZE in a
rather unusual sort of
way. sort of way. I was
moseying around Oshkosh
when I heard myself being
paged over the speaker
system.
The
whole world, or at least
the part that was at
Oshkosh, knew that I was
being ordered to report to
the Long EZ. I found Dick
Rutan hovering around the
air-plane, its nose on the
ground like a praying
mantis. He saw me coming
and motioned me over.
"Well," he said, "This is
a good time to try it on"
Talk about lack of
preparation! I had
"mentioned" to Burt that I
was giving a seminar later
in the week comparing
various homebuilt types
and how they flew. I told
him I knew everybody was
going to be curious how
the Long EZ flew and it
was a shame we didn't have
enough time to check me
out. As I stood there
beside the Long EZ, Dick
Rutan pointing out this
gadget and that, it looked
as if there really was
time after all.
In
climbing into the Long
(we'll call it by its
first name), several
things are immediately
apparent: First of all,
it's significantly bigger
inside. I never did
consider the VariEze too
tight, but the Long gives
you enough room to squirm
around in. Since I'm a
very average 5 foot 10
inch pilot type person,
I'd have to say that the
Long probably has no
limitations in terms of
pilot size, flick Rutan
looks to be a couple
inches over six feet, and
he fits fine, but they did
have to adjust the rudder
pedals and seat cushion
for me.
Another
immediately apparent
change-and one that was
very welcome-is the gear
system. Once I was
strapped in Dick picked
the nose up by the canard
(it had been sitting on
its nose), and I cranked
the nose gear down.
Earlier VariEze's had a
single stroke lever affair
protruding from the panel
that I never did like. It
was too hard to actuate,
wasn't terribly positive
and, in case of a crash,
was a sword pointed
directly at your chest.
Later VariEzes got the
crank system now standard
on the Long. You just
crank it until it stops
and that's it. Up and down
indications are simple If
you can't move the crank
in one direction, the gear
is down if it won t move
the other way, it is up- A
properly raucous sounding
horn lets you know when
you've cut the power too
far with the nose gear
still tucked in
With
the canopy down and
locked, I threw the master
and one mag switch, and
Dick threw the 0-235
through one blade. The
Lycoming knew better than
to balk, thereby risking
Dick's wrath, so it barked
into life, and Dick slid
over the wing root and
into the back seat.
Taxiing
is essentially a game
played with the brakes and
throttle. Since the nose
wheel is full swivel and
friction locked to centre,
you have to be firm on the
brakes to be certain ot
placing the nose exactly
where you want it. It's no
big deal and its ground
handling is better than a
Yankee with its similar
setup. At first I had a
little problem locating
the brake pedals because
there aren't any. You get
brake by depressing the
rudder pedal clear to the
bottom, the brakes getting
into the act at the bottom
of the stroke. Since the
rudders are totally
independent of one
another, you taxi along
with both of them
deflected outwards as you
keep the rudders depressed
to the point that the
brakes are only an inch or
so of travel away.
In case
you haven't been to
Oshkosh and flown off the
fly-by runway, you've
missed one of life's real
thrills. They run
thousands of takeoffs and
landings each day, none of
them with radios and with
next to no problems. You
taxi up to a couple of
Feds standing by the side
of the runway with orange
paddles in their hands.
They watch final for you
and when they see an open
slot, they quickly wave
you out. It's almost like
being on a land-locked
carrier. Slam, barn, thank
you ma'am! They don't
waste any time and they
don't worry about
intervals.
The guy
with the paddles pointed
both of them at me and
motioned toward the
runway, meaning I was to
take position on the
centreline. I poked the
Long in the rear (the only
place you can poke a
pusher), and it
begrudgingly worked its
way up the incline through
the grass. I was a little
slower than the second Fed
wanted me to be because of
a plane on final. He made
a frantic paddle signal
that could only be
interpreted as "Cleared
for immediate, repeat
immediate, takeoff." I
started the power up in
the turn and had full
power by the time we hit
the centreline.
I WAS
JUST A BIT GOOSEY ABOUT
THE BRAKES-only steering
and concentrated on
keeping the nose right on
the dotted line. A quick
glance inside showed me
coming up on fifty knots,
so. I tightened my grip on
the side stick and eased
it back. My only
experiences with side
sticks had been in the
BD-5 and VariEze, and both
of them taught me to be
gentle or I'd
over-control. The Lung
didn't demand that kind of
tender-ness. Even as the
nose wheel came up and we
were still running on the
main, it was evident Rutan
had learned something in
the past few years. Even
at that low speed, the
pressure gradient in the
stick was building and my
right hand could tell it
was holding onto
something.
At
about sixty knots, the
Long was off the runway
and I had my first and
most pleasant surprise . .
. I could actually see
where I was going. Believe
me, that was definitely
not the case in the
VariEze. The seating
position doesn't appear
that much different, but
it obviously is. Also, the
aerodynamics of the Long
are such that the deck
angle on rotation must be
a little flatter. Whatever
it is, the visibility is
next to fantastic. It's as
good, or better than any
tricycle airplane I know
of.
Then I
made a quick turn onto
crosswind and got my
second surprise : gheesus
does this thing ever
roll!! It actually caught
me with my drawers down.
With a very normal amount
of side pressure and stick
displacement, I found
myself whipping to one
side as if I was in my
Pitts. The pressures are
just right, the stick
travel is fine and the
response is not to be
believed. The VariEze had
been okay in the controls
department, but the Long
is close to perfect. Even
though I had just cranked
the gear up and hadn't
even left the pattern yet,
I was in love. Damned, if
it just had another wing
to make it a biplane!
Dick
said the normal best rate
of climb speed was ninety
knots, but I used 100 so I
had a better chance of
seeing the dozens of
airplanes I knew were out
there. Oshkosh is not the
place to be charging
around with your head down
and locked.
We were
climbing at about 1,100
fpm, so we punched through
8,000 feet in nothing
flat. As I pushed over for
level flight, I kept cross
checking the altimeter and
the airspeed, trying to
establish level flight . .
. which ain't easy. Level
looks nose down to me.
Really nose down! At about
2,600 rpm we wound up
indicating 160 miles for a
true of about 165 mph.
Rutan gives the max 75%
cruise as 191 mph TAS at
8,000 feet. Economy cruise
is 165 mph, which is good
for a 1,400 mile range
with both seats full,
standard fuel and baggage.
As the
speed built up, the stick
pressures increased only
slightly, if at all, but
the stability began to
approach that of a living
room sofa. At slower
speeds it seemed stable,
but you still had to pay
attention to it. At cruise
speeds, you forget about
it. Flat forget it! I ran
it up to twenty mph over
cruise speeds, quickly
releasing the stick. The
nose came back up,
overshot, then back down,
then stabilized at the end
of the second cycle. It
was equally stable on the
other two axis. It appears
to move only if you ask it
to, otherwise it will keep
on trucking straight ahead
forever or until it runs
out of gas, whichever
comes first.
Having
seen Dick's routine, and
now having tasted the
Long's ailerons, I just
had to roll it. So, I did.
A slow, gentle, positive C
aileron roll in the Long
is so silky you'd think
you were in a jet.
SINCE I
KNEW I WAS GOING TO HAVE
TO LAND IT eventually, I
chopped the power, and
dropped the gear to get a
feeling for Its slow speed
manners.
'Then I
got yet another surprise,
this one not necessarily
good but not bad either: I
couldn't slow it down. The
prototype doesn't have the
bellyboard drag flap of
the production models and
no airplane ever needed
one more! Even power off,
it was a real bitch to get
down to the approach speed
of 65 knots. This was
going to be something to
remember in the pattern.
I put
the nose on the horizon,
power off, rolled left,
and kept bringing the
stick back. Actually, I
got the stick back on the
stop almost immediately,
but the air-plane kept on
flying. The nose bobbed up
and down a little bit, but
no amount of yanking could
get the stall to break. It
also demonstrated little
or none of the Dutch roll
tendency of the VariEze's
stall. I would imagine
there is a combination of
full-aft stick and power
that would let you come
down to a survivable
crash/ landing in a
weather or night emergency
situation.
I kept
the gear out (which
incidentally doesn't slow
it down at all), and
headed down to Fond du Lac
to shoot some landings,
keeping in mind the way
this bird wants to hang
onto speed. Making a long
forty-five degree to the
downwind, I got it down to
100 and then ninety on
downwind. But ninety is a
long, long way from
sixty-five in a Long EZ.
Fortunately (I Thought)
there was a Cherokee in
front of me, so I extended
my pattern and finally got
down to sixty-five
indicated. Dick's voice
came up in the headset,
"We'll never make it,
we're too high." I looked
back at the runway and
thought he was crazy.
Still, I flew out far
enough before turning base
that I figured I'd be able
to use a little power on
final to control
glideslope and paste it
right on the numbers. Then
I turned final. Wait a
damned minute! I was on a
long final and at
sixty-five knots, but I
wasn't coming down. To
make a long story short, I
wouldn't have hit any part
of a 4,500 foot runway.
EMBARRASSING! Dick was
chuckling softly through
the hot intercom system.
Next
time around I had the
speed nailed on down-wind
and didn't use power
anywhere for anything. I
moved base leg out still
further and even then, I
had my doubts about
getting down. I was even
standing on both rudders
trying to use them as tiny
drag brakes. Then I saw we
were going to get down, so
I started trying to
establish visual
references for the flare.
I couldn't find any! As
the runway came up to meet
us, I figured the best I
could do would be to hold
it off and keep holding
it, letting it establish
its own attitude at
touchdown. Gingerly, and I
do mean gingerly, I
brought the nose up a
little, then when I
appeared to be level, it
stopped settling. Then it
settled a little and I
eased back. Still, we were
in a level attitude. Back
a little more and we still
appeared to be level.
Clunk! We were down, and
the nosewheel wasn't
touching and I still
thought we looked level.
Then I started to lower
the nose. Oh my God! My
heart jumped up into my
throat as the nose
continued down, down, and
I had the sickening
feeling I had known once
before . . . when the nose
gear on a VariEze had
failed and I fell on my
nose. Not again! Then,
clunk! The nose gear was
there all right, but the
cold sweat on my neck
reminded me how scared I'd
been. The nose sits so far
down on rollout that you
actually have the feeling
you're falling on your
schnoze, something my
schnoze couldn't stand
again.
Power
on, around we went again,
this time, I was a little
more ahead of the airplane
and beginning to enjoy it
even more. I was reminded
by Dick that I was doing
what most other first-time
Long pilots do, taking off
with at least one rudder
sticking out. And that's
one criticism I have of
the airplane, minor though
it may be. The rudder
pedal travel is something
like five inches with the
brakes being the last
inch. Since you're using
brakes for directional
control during part of the
takeoff run, you have to
mentally remind yourself
to move your feet a long
way aft to keep from
depressing a rudder
Another
minor complaint is that
the rudders have a little
too much rudder pressure
when you are at cruise
speed. The short, wide
chord rudders react very
quickly to increasing G
which puts them out of
harmony with the rest of
the controls at higher
speeds. Burt did this to
make the airplane that
much more unspinnable,
since you really have to
be standing on the rudders
to get them very far out
in the wind. It does
present a minor imbalance,
however, but one you can
certainly live with.
The
Long EZ is going to be as
important as the Vari-Eze
was, but in different
ways. The Long EZ is going
to set standards for any
machine which pretends to
be a cross-country runner.
The big wing strakes of
the Long contain enough
fuel and baggage that any
couple can easily use the
airplane as though it was
a Bonanza. The cruise
speeds and excellent
inherent stability make it
a great XC bomber, and the
seats are super
comfortable, although the
rear passenger will find
room for his feet a little
cramped. The real
advantage to the Long EZ
will become apparent when
you taxi up to the gas
pump after running ten
hours non-stop California
to Oshkosh and the final
numbers on the gas pump
are $79! It's going to be
a long time before that
number is beaten!
