Smith was a
doodler-dreamer like the
rest of us, but he was
also a doer. He collected
his notes and scratch pads
and hammered them into a
reality: a flying machine
that he thought was the
ultimate in pure fun
flying. It was everyman's
airplane, to be built
cheaply, flown easily, and
to give a degree of
satisfaction to the
dreamer. That was 1956.
This is 1970, and I am
flying Frank Smith's
reality. The wind buffets
my helmet and ripples the
shoulders of my flight
suit, and it is obvious
that Frank Smith knew what
he was doing. His little
airplane is fun -- not
dynamite, not specialized
aerobatics, not STOL --
just fun. The ailerons are
quick and light and the
aircraft has enough rudder
for nine airplanes and
enough elevator for two.
It can be flown feet on
the floor, if you wish,
because slamming the stick
hard to one side pivots
the nose on a point.
There's no adverse yaw,
although the nose slides a
bit when rolling out
without rudder.
Frank Smith built the
first Miniplane and flew
it in 1958. He drew up
plans and got everything
set up so his airplane
would be available to all
those dreamers who are
doers, but not designers.
His plans are complete and
better than many on the
market. They are done in
the form of a small book
of black line drawings,
and while adequate to
build the airplane, they
are far from production
drawings. On the other
hand, you have to fork
over only $35 rather than
the usual $125. The Smith
plans leave a lot to the
imagination, but I think
that's part of the game.
The Mini we flew, N391Y,
would make Frank Smith
proud. Right now it's
making its owner, Bob
Sweeny of Pennington, New
Jersey, proud. The plane
was originally built by
Lester David, also of New
Jersey, and he foresaw
changes that were later
incorporated into the
plans. His was probably
the first Miniplane with a
beefed-up tail, a trim
tab, and double flying
wires. The craft changed
hands several times and
wound up with Bob Sweeny.
Bob apologized to me for
two patches in the
otherwise spotless fabric.
It seems a rotary
mower threw a blade
through a hangar window
and nearly gave 91 Yankee
an appendectomy.
Considering the
fantastically clean and
detailed quality of the
airplane, I was more than
willing to overlook a few
bandages, especially since
he was going to let me fly
it.
Except for the
modifications already
mentioned, 91Y might have
been exactly what Smith
had in mind when he
squatted on his garage
floor, chalk in hand. The
airplane is traditional
wood, tubing, and fabric.
It's basic. Airplanes have
been built this way since
Orville talked Wilbur into
giving up the bike shop.
The wings are straight and
square, making everything
as simple as possible.
There are no angular
splices to make, no really
exotic fittings, and all
the ribs are the same
size; they are the usual
truss type built out of
spruce strips. Some
builders have incorporated
pressed aluminium ribs,
but that is personal
preference. Since there
are no ailerons in the
upper wing, there is no
complex cable assembly,
nor any pushrod
interconnectors. The top
wing is actually a simple
slab and looks as if it
could be built on a big
kitchen table. The
original Miniplane was
pulled around by a C-85
Continental, but people
have shoe-horned engines
as big as 150 hp, although
that would probably
require additional beefing
up or prayers before each
flight. Sweeny's plane has
the C-85.
In the interest of
simplicity, Smith put a
rigid gear on his DSA-1
(Darned Small Airplane),
but more and more builders
are changing to some sort
of sprung gear. Some use
the tried and true
spring-in-a-tube shock
system, while others throw
the gear Vs away entirely,
preferring to use a
Cessna-type flat spring
gear.
Shortly after I flew
Sweeny's airplane, he
changed his gear, and I'm
glad he did. I hit a bump
while landing it on grass
and it threw the little
airplane quite a way back
up into the air, causing
me to break into an
instant sweat.
A Miniplane fits well; it
really feels good. Some
homebuilts make you feel
that accommodating your
body was an afterthought
in the design, but the
Miniplane is extremely
comfortable and well laid
out. My medical says I'm
70 inches tall and weigh
155 pounds, so any
average-sized pilot should
have no trouble fitting,
though the bigger types
might prefer a little more
leg room. Visibility over
the nose is excellent. I
was really surprised at
how flat the airplane
sits. Even though it's a
tail-dragger, the far end
of the runway roosts on
the top edge of the
cowling.
Bob Sweeny has more
tailwheel time than most,
nearly 1,000 hours of
Citabria time alone, but I
just couldn't believe 91Y
was as squirrelly as he
kept telling me. However,
since I'm not particularly
an ace, I was prepared to
believe him. I figured
it's short, narrow, and
rigid, so I'd play it
safe.
Taxiing out, I didn't
notice anything
particularly scary,
although the brakes were a
little soft and I couldn't
maneuver as tightly as I
wanted. The airplane made
a believer out of me the
second I put the power to
it. Maybe I've never flown
a real airplane, but I've
never flown anything that
kept me as busy on takeoff
as the Miniplane. This
isn't saying that it wants
to run for the bushes, but
it does have a little
torque, and it reacts
immediately to the
slightest amount of rudder
pressure. It's nearly
impossible to keep the
rudder perfectly centered,
so I was constantly using
a little rudder one way or
the other.
I had the nose a bit too
high when I broke ground
and it wanted to settle,
but when I dropped the
nose and let the speed
build, it climbed out just
fine. Once in the air, the
feeling of chasing it down
the runway disappeared. It
climbed at 85 mph and at
about the same rate as a
Cherokee 140.
I don't have a great deal
of open-cockpit time a few
Jungmeisters, the Jungster
I, and a Fly-baby-so it's
difficult to give a fair
evaluation of the wind
noise and general cockpit
characteristics. I do
think that the Miniplane
afforded my noggin about
as much wind protection as
anything else, and more
than some. The wind could
play with the top of my
head and the back of my
shoulders. Other than
that, there was
practically no wind
disturbance in the
cockpit.
I've already mentioned how
nice the controls feel.
Some airplanes are
supersensitive and give
you that tightrope
feeling, but the Miniplane
is quick enough to be fun
while not demanding. The
ailerons are much like a
Swift's, but the rudder is
like nothing else-it has
lots.
I hate to admit it, but I
fell out of two loops
before I got a good one.
The airplane is very
sensitive to the amount of
G force you pull going
into a loop. Too much or
too little G and you slow
down, winding up as I did
-- looking around and
seeing nothing but blue,
wondering where the ground
was, while the airplane
tries to make up its mind
which way to fall. It
definitely needs more
power, but once you figure
out how to play the game,
the 85 is enough to give
passable loops.
