First flown in 1955 the F8 was
destined to become a production
aircraft from the word go.
Licensed by Frati, Italian
companies, Aviano Milano,
Laverda and Aeromere
manufactured some 110 of these
all wood,
2 seat aircraft between 1955 and
1958, and sold them as sporting
and touring aircraft to the well
heeled of mainly Europe, but in
1958 metal aircraft were what
the well-dressed aviator was
wearing and production ceased.
The
last 20 aircraft came out of the
Laverda of Italy factory and
that was it for the Falco for
the time being. The all metal SF
260, very similar in appearance
but with more power up front,
260 hp, went into production
later, but that's another story.
In
1975, one Alfred Scott, having
made pots of money out of real
estate in the USA, bought the
rights to the out of production
Falco. He and David Thurston,
more famous he designer of the
Lake Buccaneer amphibian, set
about the task of redrawing and
converting from metric, the
plans of the Falco, to better
suit the US home-builder market.
After plans came the kit
components and the Falco is now
an established home-built
design, in plans and kit form
available from Scott's company,
Sequoia Aircraft.
The first plans built Falco,
built by Larry Wohlers of
Tucson, Arizona, flew in June
1982
The subject of our story is
Brian Nelson of Robinhills,
Randburg, Gauteng and the Falco
F8 that he has been busy with
for the past 12 years - yes you
read it right, this is a BIG
project.
In fairness though Brian admits
to often, for periods of months,
not having been able to do much
building due to work pressures
and other commitments. However,
when pressed he will also admit
that he is entertaining serious
thoughts that this machine will
be flying this year, the
centenary of powered flight!
Brian started out in November
1983, by purchasing the plans
for the Falco.
After studying these for a
little time, he shoved them back
in the drawer - the project
appeared just too complex and,
he felt, too much for his skill
level at that time. He had for
many years been involved in
model aircraft building but this
looked too ambitious!
Two
years later, still determined to
build an aircraft, he bought the
KR2 spruce kit from the local
agent of KR aircraft, the late
Sakkie Halgreen. This appeared
more realistic for a first time
builder. Well, after a couple of
years of building with wood, he
felt much more confident of his
skills with the aircraft 70%
complete.
On
a trip to UK, he met the UK
agent for Falco aircraft, Brian
Fox - and got his ear bent, to
the extent that on his return to
SA the KR project was sold, and
in January 1988, Brian started
on the Falco, which is what he
wanted to do in the first place!
Who says there's no justice in
this world!
Having been a production
aircraft the Falco makes a very
impressive homebuilt Apart from
it's self-evident good looks, it
is consequently a very well
proven design in all aspects -
construction, performance and
safety.
Recent revelations regarding the
stability and centre of gravity
problems of some hot composite
kit aircraft have convinced
Brian that his choice was
correct - he does not expect to
have to move the wing later to
correct the longitudinal
stability of the aircraft like
some Glasair builders!
The
Falco is clearly not as
quick to
build or as simple as some
designs available, although
comparisons of manufacturer's
claimed build-times are odious!
Neither is it cheap to build -
as Brian pointed out - if you
were to purchase all the kit
segments available from Sequoia
you would be in for about $
60,000, but building would be
dramatically faster, and easier.
In Brian's case he has purchased
some ready made components and
manufactured all the rest. For
example he bought the canopy,
cowling kit and seats :from
Sequoia - the canopy is bigger
than that of a full size P51
Mustang - but kits such as wing
spar, tail group, fuselage,
engine mount, main and nose -
gears he has made himself or had
made locally, thus saving a bit.
If you look at only the price of
the main gear/nose gear/gearbox
and motor components at US $
2100 it's more than a bit!
To illustrate the savings
possible, his landing gear was
made of locally available honed
hydraulic tubing, which although
to a German specification ST 52
and of a different alloy that
the US-supplied article,
exhibits all the same
metallurgical and mechanical
characteristics - and Brian
should know - he's a
metallurgical engineer).
These were manufactured for
Brian and for two other Falco
builders, Fanie Hendricks of
Standerton and Koen Plantinga of
Edenvale, by a retired uncle of
Brian who was in the engineering
business and had retained, on
retirement, some of the
equipment he used in his
business. Cost to each builder
R10000 - don't you Cove it when
a plan comes together!
The 160hp Lycoming 0-320 B2B,
complete with CS prop and
spinner, came from a Piper
Apache found sinking into the
weeds at Maputo Airport - but
with 0 SMOH in the logs it
looked like a great deal.
However a strip down and
examination recently, after the
motor had lain in a corner of
the workshop since purchase for
many years revealed that,
notwithstanding the logbooks,
the motor was on the point of
failure, with scuffed and
possibly previously seized
pistons and more...!
So, after a complete disassemble
and rebuild, the motor has now
been installed to the airframe,
and for the first time the Falco
is able to stand on it's own
wheels, now that there is some
weight up front.
The Hartzell Constant-Speed
propeller with which the motor
was bought was also found to be
well outside service limits and
will be discarded in favour of a
fixed-pitch wooden propeller -
just like the original Falco.
Brian has been an EAA member
since 1983, and has served in
various capacities on EAA
Chapter and National committees,
including a stint as President
of Chapter 322 (1985 - 86) and
as National President (1986 -
87), since being asked to step
in when the then National
Treasurer, Joe Higharn died in
an accident.
He has served on the FAI Amateur
Built Aircraft Commission as
representative of Aero Club of
SA, and was elected President of
ABAC in 1989 - 1990. One of only
four Presidents of Honour
appointed by the Amateur Built
Aircraft Commission; the others
being Paul Poberezny of EAA US,
Louis Cariou of Resau du Sport
de I'Air (France) and David
Faulkner-Bryant of PFA UK for
contributions to aviation.
