Taylorcraft BC-12D pilot test report
You can almost guess how long an
individual has been aware of classics of
the late 1940's by the amount of awe in
his or her voice when seeing a pristine,
restored BC-12 Taylorcraft. The reason
for that is the image many carry in
their minds of a Taylorcraft is of it
sitting lop sided on the back tie down
line, one tire flat, a bird-nest
apartment in the cowling and mice
running up and down inside the rotting
fabric. Cubs and Champs never slid down
hill as quickly as did the Taylorcraft
breed. Even though every pilot on the
airport recognized that Taylorcrafts
were far faster than the rest of the 65
hp group (with the possible exception of
8A Luscombes), the airport hobo was most
likely to be a Taylorcraft.
There's no good
explanation for the Taylorcrafts past
image except that there were just so
many of them around, some were bound to
go down hill. Although never produced in
the same numbers as the Cub, as soon as
old C. G. Taylor introduced his side by
side Model A in 1937, the market forced
him to crank them out like cookies. It
wasn't unusual for the factory to be
doing 30 airplanes a month in 1938
before the depression had even wound
down.
The Model A's had the
less then overwhelming A-40 Continental,
but it performed so well, every one
loved them. Then came the first of the
overhead valve Continentals, the A-50 (Taylorcraft
Model BC) and then a shining knight came
riding over the horizon in the form of
the Continental A-65. The A-65, more any
other single technological event, made
the Taylorcraft and every other of its
peer group take a giant step forward.
What had been a good airplane became
astoundingly good.
C. G. Taylor had an
eye for building clean, low drag
airframes. He got his lift from lots of
wing and his speed from low drag. On the
same engine with which a Cub could
barely make 80 mph, the BC-12 series was
easily doing 95 mph and some would touch
100 mph.
Taylor built
thousands of airplanes before the war
shut him down to start making L-2's.
After the war, they cleaned up the
airplanes still further and introduced
the BC-12D. There are probably more of
this model existing than any other. By
the same token, more BC-12D's died on
back tie-down lines than any other given
type. Go figure!
Mechanical
Description
Considering that it was built to beat
the Cub and humiliate C. G. Taylor's
late business partner, William Piper,
there's very little Cub in a Taylorcraft
BC. In fact, he did everything he could
to do it different and do it better.
The side-by-side
seating was a major departure, as were
the novel, for the time, control wheels
sticking out of the panel. Boarding was
via an automotive type door on the right
side. Eventually, another door on the
other side was offered and became
standard in later postwar airplanes.
The wing's airfoil,
rather than being the flat bottom Clark
"Y" or USA 35 everyone else was using,
was a semi-symmetrical 23000 series
known for low drag and less gentle stall
characteristics. For a wing that long to
be that fast with such a small number of
ponies available, it had to have a
low-drag airfoil.
The pre-war airplanes
used 1025 steel tube or a combination of
1025 and 4130. Postwar airplanes are all
4130. All of them have to be inspected
carefully for rust, if nothing else
because they are so old and most sat out
for so long.
The wings use
pressed-aluminium ribs over wooden spars
which also need careful inspecting.
Besides age, a surprising number of the
aircraft have been ground looped at
least once and the incident may or may
not be in their log books. The wings
have a lot of overhang past the strut
attach points and they could easily have
spar cracks which don't show except
under careful inspection.
Most Taylorcrafts use
Shinn brakes which are mechanical shoe
types with the lining on the drums, not
the shoes. Considering that the airplane
really doesn't need brakes most of the
time, the brakes work just fine. Their
cams can wear, but the units are easier
to repair than most of the period.
The A-65 Continental
engine is the standard by which all
small reciprocating engines are
measured. It's reliable, user friendly
and easy to maintain. Parts are still
available and overhauls still relatively
inexpensive, when measured against more
modern engines. If the mag. coils are
good and the timing is remotely right,
the engines will catch on the first or
second blade every time.
Flight
Characteristics
We prevailed on Gary Towner, an FAA
airline maintenance inspector in
Phoenix, to let us use his freshly
restored BC-12D as the test vehicle to
remind us how a T-craft flies. Towner
says when he bought his Taylorcraft, it
was a flying airplane but in need of
complete restoration. In the course of
taking it apart he found the spars were
riddled with cracks. As he put it,
"...they were really scary looking." He
feels all owners of aircraft that old
should take note of his experience in
that area.
His airplane was, as
near as he can determine, originally a
BC-12D-1, which he says was the bottom
line, low-buck airplane that didn't even
have a left door. The second door was
added sometime in the 1970's by a
previous owner.
As with most
two-place, side by side airplanes of the
era, getting in is as much a project as
flying it. In the T-craft it is made
more difficult by a diagonal brace
running across the end of the seat.
Once loaded up, Gary
and I were, shall we say, "cozy." Our
shoulders were definitely touching part
of the time. We didn't measure the
cockpit, but it is probably several
inches narrower than a C-150/152.
Visibility over the nose, however, was
good without even stretching. This was
important because the headliner was
nearly touching my head and I would have
touched it if I had to stretch. Part of
the Taylorcraft's speed comes from
having low frontal area and this means a
low cabin. It is low enough, in fact,
that turning your head sideways puts
your eyes right in the middle of the
wing root. To see to the side requires
ducking down quite a bit. This is more
of an aggravation than a danger, but the
lack of visibility is something to be
remembered at all times.
The big control
wheels are fun and the brake pedals are
funny. They are two tiny, thumb sized
pedals located well back and right
between the rudder pedals. They are
nearly touching one another.
Fortunately, they are used very little
in normal flight.
Taxiing is straight
forward with the only complication being
having to look down to dial frequencies
into the handheld radio mounted between
us on the front seat edge. That location
keeps the cockpit looking absolutely
original.
I hadn't been in a
Taylorcraft in years and my primary
memory was one of the airplane flying as
if it was very light. Gary's airplane
re-enforced that memory. As soon as the
power was up, the airplane wanted to fly
and I barely had the tail up before it
floated off. The tail is so far behind
us, it has lots of authority so very
little rudder movement was needed to
keep it straight. We had barely a breath
of wind, maybe two or three knots,
across the runway. Most airplanes
wouldn't have even noticed that wind,
but the second we left the ground, the
Taylorcraft instantly reacted to the
wind by drifting. I found myself
crabbing into a wind the windsock barely
recognized as being there.
The airplane has a
definite thistle down feeling to it and
wind is a challenge to it. The best
pilot on any airport is the Taylorcraft
pilot who easily and routinely conquers
a gusty crosswind. With firm hands, the
airplane will handle more crosswind than
is prudent, but most folks study the
windsock carefully before pulling the
airplane out. With such a light wing
loading and those long wings, it's
second cousin to a parachute.
It was fairly cool
out, about 70°, and the airplane
responded by giving us a fairly solid
rate of climb in the 400-500 fpm range
at about 65-70 mph. Gary says he gets
about half that during the summer and
prefers to fly the airplane solo in
those situations.
The air was liquid
smooth so we didn't have much turbulence
to show the Taylorcraft's cork-like
ability to ride over even the softest
bump. We also didn't have any thermals
to help us to altitude. More than any of
its peers, the Taylorcraft is eager to
lock on to even the weakest thermal and
convert it into altitude.
As we levelled off,
the airspeed stabilized at 90-95 mph and
Gary says he can flight plan 95-100 mph
and be fairly close. He's generally
burning around 4.5 gallons per hour and,
considering his airplane has both wing
tank options as well as the fuselage
tank, the airplane will stay in the air
far longer than he can. The ability to
go long distances in a reasonable time
on pennies has always the Taylorcraft's
long suit.
Because Gary had gone
completely through the control system,
including installing ball bearing
pulleys, his controls were surprisingly
smooth. There was none of the common
feeling that a cable was sawing a pulley
in half. Also, when racking the ailerons
around, the airplane was quite willing
to respond. We're not talking Pitts
Special roll rates here, but even with
those long wings, it rolled faster than
most of its peers.
Adverse yaw is
significant, but not as much as a Champ
and about the same as a Cub. The amount
of rudder required to coordinate is
minimal, but definitely there. In
checking pitch stability, it damped out
completely in less than three cycles
when pulled ten mph off trim speed.
Doing stalls was, as
is usually the case with this period of
airplane, almost a waste of time because
they are so benign. In a normal, slow
approach to a stall, the wheel hit the
stop somewhere in the low 40 mph range
and the airplane just mushed. If
accelerated, either in a turn or
straight, it would break slightly and
then mush. During the process I was
careful to keep the ball centred because
the rudder is very effective at those
slow speeds. As I remember, if asked,
the airplane spins very nicely and
willingly, with a positive recovery.
There's no doubt
you're in a fairly small cabin, when
cruising. Even though you can see over
the nose quite well, your eyes are
closer to the thrust line than we're
used to so the visual down angle is
pretty flat. Also, the necessity to duck
to see sideways is always there. The
overall feeling is one of being in a
long, narrow cabin, when really it's the
vertical height that gives that
illusion. Skylights would probably open
up the cabin feeling considerably.
When we came back
into the pattern, I reminded myself that
this airplane would really glide, so I
spaced us out accordingly on base. Even
so, I was too high. Fortunately, the
airplane is a good slipping machine. Not
as good as a Cub, but still good. Gary
said he uses 70 mph, so I did too, which
seemed to work out fine.
As I came out of the
slip and into ground effect, the
Taylorcraft's reputation as a floater
was again re-enforced. We may have been
a little fast, but, as we floated along
while I felt for the ground, I was very
conscious of having to be very judicious
with what I did with the elevators. Just
the slightest amount of too much back
pressure and the airplane would try to
balloon. Since we were slowing to a
near-walk this was more of a game, than
anything else. The airplane clearly
telegraphed when it was about to settle
or balloon and I just had to adjust
accordingly.
After a few seconds of floating, it
would give up and settle on to the
ground. On one, I held it off just a
little too long and felt it unhook and
drop us the last several inches. That
surprised me, but shows it's not a good
idea to hang it on top of ground effect
for too long.
All of the landings
were three-pointers, some better than
others, and none were even remotely
challenging during roll-out. The
airplane didn't want to do anything
unusual and was at least as easy as a
Champ or Cub to control. The wind had
pretty much died down, so we had the
best of all possible situations going
for us.
The T-craft is
actually quite a good bargain, even in
this period of rapidly inflating classic
airplane prices. A quick perusal of
Trade-a-Plane showed that even the
restored airplanes seldom touched
$20,000 with many restored ones with
low-time engines at $15,000 and below.
Un-restored airplanes were in the
$10,000-$12,000 range. When buying an
un-restored airplane, however, inspect
it very carefully. At sometime in its
life, it was doing duty as shelter for
all types of mice and varmints. When
buying a newly recovered airplane, make
certain all the rust and rot problems
were attended to. |
