It is noted
first that a description to all the bits and pieces regarding the conversion
is nearly impossible. Many many parts were made based on pictures, drawings,
estimates and a lot of scratch building.
About 50% of
the parts could be used in some way of the Puma kits, the rest was scratch.
This building report can only show some items. But enjoy! |
Fuselage
Conversion
First, the fuselage had to be lengthened
for the Cougar conversion. Measuring the overall fuselage is quite complex.
The main dimension to keep in mind is the overall length from nose to tail
tip. (see also the drawing on page [1]
). See also page [3] as the tailfin chord
is also a bit larger.
Besides the lengthening, the Dutch
Cougar has different windows. Cutting out the various windows and giving
them the correct size should now be done and is obviously important. The
dimensions of the various windows were determined from the drawing and
checking also with the 1/72 Italeri kit. Filing, sanding and cutting was
now done at the various fuselage parts. The various windows have raised
edges. These were made with metal wire.
(The windows were not fitted at this
stage; the windows are made from transparant acetate sheet, the various
windows cut to size. This is quite a tedious job. They also got a coat
of Johnson Future to give some more glass
effect on the windows ).
The original Puma fuselage part is
seen in green (upper), at the lower in white with 2 extra openings made
for additional windows, with stretch sections for the Cougar in black.
"Left overs" after cutting...
Also, the floor seen right is the
extended floor using two floors from 2 kits.
The extened fuselage was now first
constructed. As there are two large side doors, adding all the internal
details within the cabin is not required at this stage.
The extended floor was added, and
also a roof added in the upper cabin from card. Also some details at the
fuselage cabin sides were added made from plastic strip.
The Cougar has a different and longer
rear cone at the rear fuselage as compared to the (Super) Puma. It is the
fairing towards the tailrotor boom that needs another extension to make
the composite fairing typical for the later Cougar AS 532 variants. Some
Puma parts were used with white plasticcard and sprue for strength (see
page
1 for dimensions).
Milliput was
required to get a smooth straight cone shape. A lot of work was needed
here. The cone shape is rather straight tapered.


The larger window situated in the
cone made things difficult and required some extra plastic strips glued
on and sanded in shape.
Most of the AS 532 Cougars also have an added fairing with a hatch at the
lower side of the cone. So does the Dutch Cougar. This was made from straight
card.
Here, the glued on tailboom can be seen. Internally plastic strip and rod
were used to get the necessary strength. Also, an additional small box
can be seen added to the side.
Nose cone

The longer radar nose was moulded
from Milliput. The clear cockpit windows were cut off and are to be added
later on after the basic model has been correctly shaped.
The lower cockpit section can be
seen here (after main fuselage assembly) with added fairings and various
stubs. Quite some work is needed here to get a smooth result.
