The construction of flying models is very different from
most static models. Flying models borrow
construction techniques from real full-sized aircraft (although models rarely use metal structures.)
These might consist of forming the frame
of the model using thin strips of light wood such as balsa then covering it
with tissue paper and subsequently doping the tissue to form a light and sturdy
frame which is also airtight.
Flying models are usually what is meant by the term aeromodelling. Most flying model aircraft can be placed in one
of three groups:
Free flight
(F/F) model aircraft fly without any attachment to the ground.
This type of model pre-dates the efforts of the Wright Brothers and
other pioneers.
Control
line (C/L) model aircraft use cables (usually two) leading
from the wing to the pilot. A variation of this system is the Round-the-pole flying
(RTP) model.
Radio-controlled
aircraft have a transmitter operated by the pilot on the ground, sending signals to
a receiver in
the craft.
As a young lad all those years ago it was the free flight
model out of the three types described above that really caught my imagination.
Control line and radio-controlled aircraft were not powered by a rubber band
they required a real working motor which was much too expensive for me at that
age, and as for radio-controlled, I could forget that completely.
I
remember whenever I saved up a few shillings pocket money, off I went hurrying
down to that wonderful Aladdin’s cave, the venerable Lockhart’s toyshop on Hill Street. It was a fantastic place. I loved to see all the toys on display. There were Hornby train sets busily engaged in
a seemingly endless journey around a circular track, and Airfix models of cars,
boats and aircraft, all of them fully assembled and painted, displayed either
on their own individual stands or as was the case with the model aeroplanes
hanging from the ceiling.
After
making my purchase I would hurry home, as I was always dreadfully keen to start
building my new model aeroplane. Building
those balsa wood kit models was every bit as enjoyable as flying them.
Inside
the box that the model came in you would find: a set of assembly drawings
(plans), a roll of tissue paper, plus all the lengths of balsa wood required.
First
I had to commandeer the kitchen table and then set out the assembly plans. I
would pine the plans down on to a large wooden board that I kept especially for
that purpose. Then I would carefully cut
all the little pieces of balsa as they were needed, lay them down on top of the
drawing and carefully glue them in place.
The
whole building operation could be a long process taking perhaps a few days so I
had to be prepared to vacate the kitchen table when my Mum needed the use of
it. That was the idea of doing the
construction and using a large wooden board to work on. When I had to stop working on my model for any
length of time then all I had to do was scoop up the loose pieces of balsa so
that they could be returned to their box. As for the board with the plans pinned to it,
plus the part-finished aeroplane, well, it could quite easily be slid under my
bed. That way everything was tidily
tucked away until I was able to resume work again.
When
you finally have the fuselage, wings and tail plane of the model completed it
is now time to cover the structure. For
this you use the tissue paper supplied with the kit. With this tissue paper you cover the entire aircraft
including wings and tail. The tissue
paper was stuck to the balsa wood using white or clear glue. Then comes the tricky part! All of the tissue has to be covered lightly
with a clear dope. The dope when it
dries out has the effect of stretching the tissue paper tight over the wooden
structure: so tight in fact is the doped
tissue paper that it resembles the skin of a drum.
You
had to be very careful when doping the model because if you applied too much
dope you were in great danger of warping the structure. The wings especially
needed careful attention. It was always
better to keep the wings pinned flat down to the wooden board during doping and
leave them pinned down until after the dope had well and truly dried out.
At
last comes the big day when your model aircraft is ready for its maiden flight!
Finally you will see your little plane
take to the sky, you will watch as it soars on high, riding the thermals,
defying gravity for that short space of time and then gliding gracefully back
once more to earth.
The
construction of flying model aircraft is not all that dissimilar to the
building of the real full size airplane. In the 1965 film The Flight of the Phoenix starring James Stewart and Richard Attenborough, an
aircraft crashes in the Sahara and one of the
survivors says he’s an aircraft designer and that he can build a flyable plane
using the wreckage. They are successful
in the attempt and manage to fly to safety. But as it turns out, the aircraft designer is not an aircraft designer
at all; he is the designer and builder of flying model aircraft!
Real
craft skills, those that are not casually or easily learned, can provide a child
with hours of fun, and offer one thing more: pride in a true accomplishment. A child who has built a real stick-and-tissue
model airplane, one that really flies and flies well, will feel pride not only
in ownership and use of the new toy, but also pride in the ownership of a new,
larger self.
These are lasting
experiences,
the basis of genuine self-esteem.
