... back to Jaguar
Jaguar GR mk.1 /A
kit in 1/72 was made. As previously other interesting Jaguars were made
(see other pages), this kit will be converted
into a model of a Jaguar used for "Active Control Technology" (ACT) testing.
I got a spare decal sheet from my modelling friend Bas, from COMBAT
DECALS set CD72-005.
The Jaguar ACT
was a former RAF Jaguar GR.1 coded "XX765" that flew in active service
for about half a year with no. 14 squadron at Bruggen in Germany and later
also for 17 squadron and the OCU at Lossiemouth. As research work was done
at British Aerospace (BAe) on Fly-by-wire technology and active
controls, this aircraft was used by BAe and RAE and modified for the job.
It got a digital quadruplex fly-by-wire system.
The Jaguar ACT
first flew October 1981 and was painted in the typical "raspberry ripple"
scheme of gloss signal red- white and "Oxford" blue.
done at Warton but also Boscombe Down and the RAE Farnborough. In 1984
externally large wing root extensions/ strakes at the intake sides were
added to move the centre of lift more forward to developed further fly-by-wire
control laws. During tests also some smaller modifications were done internally
with for example weight distribution and also external fuel tanks sometimes
fitted. The ACT Jaguar performed also at the SBAC Farnborough air show
in September 1984.
About 100 test
flights were made until end 1984. All things learned were used for the
subsequent development of fly-by-wire systems for the EAP
and later Eurofighter / Typhoon.
Later jaguar "XX765" was used for some other ground testing and as teaching
aid for university students. It later went on display at the RAF Cosford
Air Power Journal , Volume 11 has a very nice Jaguar special, including
the ACT test aircraft.

First, I opted to have the Jaguar
ACT model with drooped flaps, ailerons and slats as often seen on parked
aircraft (This was done previously on some of my Jaguar models). The remainder
of the model was to be kept clean e.g. without stores so this would add
some interest to the model.
So, the rear section of the flaps
were removed with a fine Tiger razor saw.
The upper wing area removed was "closed"
with thin card and the removed flap lower area sanded to get the "flap".
The seperate slotted forward flap was made of thin card.
The leading edge slat was simple
cut in at each side and tilted/drooped with some bending down.
The main model parts of fuselage,
wing and nose were now first simply assembled. A little putty was needed
in some places and sanded when dry. A first base coat of grey was applied
with the airbrush and any flaws corrected with putty again.
NOTE: the airbrakes were to be replaced
(as on the other Hasegawa kits) with home made ones from thin aluminium
foil sheet in which it is much easier to make the holes. (these air brakes
are almost always drooped down for a parked Jaguar). So these air brakes
were not yet set in place.
The model's largest conversion
work to get the model as a ACT Jaguar is now done: add the two
large wing root strakes.
These were made of 1,5 mm thick plastic
card, sanded in shape using the drawing the decal set and the model edges
at intake and inboard wing leading edge.
The drawing was enlarged to 1/72
scale to get a pattern. The leading edges of the strakes were sanded sharp
but blunt at the rear to join the model.
Getting the strakes of this ACT Jaguar
model smooth with the model airframe using putty and sanding is quite a
task, no less than 4 passes of filling and sanding were needed.
For the Jaguar ACT the usual
RAF laser nose ( parts #C10+C11 ) as well as the normal RAF vertical tail
A lot of work in this model is the
paint scheme, it all needs extensive masking for all the coloured areas.
But first, the two bulges on top
of the strakes were set in place as seen on the ACT Jaguar, these were
made of thick card sanded in shape.
Another light grey base coat was
airbrushed onto the model to check for any flaws.
After assembly, the model got first
a base white coat to check for any errors. Well, again some filling and
sanding was needed at the ACT wing strakes. Here we go again!
When finished, it was time for the
colour scheme. Get the masking tape ready! I often use low tack tape from
FINELINE but other tape brands are fine too.
For the Jaguar ACT "raspberry ripple"
paint scheme I used these acrylic paints:
RED: Revell Aqua 330 "feuerrot"
WHITE: Gunze Sangyo white H1 ;
BLUE: Gunze Sangyo blue H15;
Note that "XX765" had some small variations
in paint scheme during testing, particularly regarding the red edges on
the strakes and slats.
All colours were applied with my
So, the colours were applied with
the airbrush, starting with the white as seen above.....
.... followed after masking the larger
red (rear) areas and than after masking...
.... the rear areas of the blue.
All masking tape was removed after the paint had dried. The model looked
great and was ready to get the splendid COMBAT DECALS from set CD72-005
as it had gloss coats.
Note that the thin red striping were
made from Signal RED XTRADECAL decals I had. Masking these thinner red
lines can be done, but is very difficult. So I decided to use decals here.
The other details to be painted are
the light grey gear legs and the zinc chromate wheel gear bays and air
brake recesses. This was done with a paint brush.
After decalling, the landing gear
was installed, windscreen and canopy painted and the smaller bits and pieces.
Cockpit interior "admiralty medium grey" with black details. Anti-collision
lights were added on fuselage top and bottom and wing tips using Micro
Kristal Clear painted in Tamiya clear blue and red and and the smaller
antennas painted yellow. Also the different pitot tubes and test air data
probes set-up was installed at the ACT Jaguar nose made from scrap. The
black anti-glare panel on the nose came from a decal. The landing gear
got a few "hydraulics lines" made from thin stretched sprue and pianted
For the nose pitot tube part #C13
The kit seat was replaced by a resin
one with more detail I still had from PAVLA S72024. Main seat colour is
black with field green survival and para pack and painted straps.
After 24 hours, the model got a couple
of gloss clear varnish coats with Johnson Future/ Pledge applied
with the airbrush. This gives a nice even shine and protects the dceals.
The canopy got 2 small mirrors made from aluminium foil inside and was
installed opened up. That completed this nice Jaguar ACT model.
