I bought this vac-form kit some
years ago and decided, after a cursory inspection, I was not up to the task at
that time. As my experience grew and I became aware of the future release of the
F.6 by Trumpeter, I finally decided to give it a go. A thought process over some
months finally gave me the solution to a major problem. I particularly wanted
this F.6 with ventral gun/fuel pack and OWTs. My research, and that by others,
showed fairly conclusively that XS903-BA (black spine/fin) never flew with
over-wing tanks (OWTs). The eventual solution which came to me (not copied,
original?) was to make the tanks removable and fit small ‘panels’ to hide
the tank mounting holes. As an extension to this thinking, I also made the model
so that it could be displayed in four configurations: (a) devoid of stores as
photo above, (b) ferry configuration with ‘slippers’ on stub missile pylons
and OWTs, (c) squadron service with Red Tops, and (d) a ‘whifer’ with Red
Tops and OWTs (photo at end)
As a first timer to vac-forms,
injection moulded kits did not totally prepare me for what lay ahead. Whilst
Frank Brown had done a tremendous job with the shape of the aircraft, the
problems (or challenges if you prefer) come from the limitations of vac-forming
and white metal parts i.e. little and/or soft detail unlike injection moulding,
wider/soft panel lines, no panel screws (not rivets) and ‘rounded edges’ to
many components which should be angular. I also used the Flightpath Detail and
Weapons set, but it was not as useful at it appeared at first inspection.
However, what parts could be used certainly helped in the areas for the cockpit,
MG bays, jet pipes and resin missile bodies.

All sub-components were either
heavily modified or scratch built in order to get a good level of detail, some
of which are shown here:
[1] Cockpit – Echelon and
Flightpath versus scratch built. The F/Path tub was of no use, but the main
instrument panel and film instruments were incorporated to give very good
detail. See photo 03
Completed shots of the cockpit tub
are, unsurprisingly, difficult/impossible to take when within the fuselage.
See photo 04
[2] Ejection Seat
The kit white metal seat (left),
progression to basic shape (middle) to competed seat (right). I elected to place
the straps up over the head box, as was the tendency, to keep all the straps and
back cushion from ‘falling’ forward. See photos 05 and 06
[3] Intake trunking and Engine
Compressor Face. I beefed up the joints to the trunking outside, as this
was thin in places and I didn’t want a ‘failure’ at an inopportune time.
F/Path compressor blades otherwise scratch built components.
See photos 07 and 08
[4] Fuselage vents, scoops, drains
etc of which there is a humongous number on both sides of the fuselage and to
the underside. A variety of methods were used, from plastic tubing to scrap
resin and plastic card, with thinning to fuselage inside with a SM blade No10
for NACA inlets. See photo 09
[5]
Landing Gear
There was a heavy frosted finish to
all castings. I initially used an old flat needle file to remove the worst and
then finished with Wet and Dry paper. Also removed most of the detail and
reformed from plastic sections and resin scrap pieces. Drilled for wheel axle
and detail. See photo 10
The kit main gear legs and brake
units were formed as one in white metal with results as previously discussed.
After removing all the detail, the brake units, scissor links were reformed and
detail such as brake lines, Bowden cable and walking joints added. See
photos 11 and 12
[6] Main Gear Bays
There was little detail in the main
gear bays (left) so I totally rebuilt the bays in order to make use of the
F/Path PE ‘roof’ components (right) and then add the details. See
photos 13 and 14
This photo shows the basic components after
removal from the formed sheets. It comes as a bit of a shock to those of
us that are spoilt by quality injection moulding. However, the thickness
of the vac-form plastic lends itself to a good amount of re-scribing and
sanding.
[7] Radar Bullet and Nose Gear Bay
Rather than using the kit methodology of fitting the lower pylon mount through the intake trunking, I opted to separate the lower pylon mount from the gear bay and make a completely new NG bay. This aided both the detailing in the gear bay and the intake.
See photos 15, 16 and 17
[8] Jet Pipes and Nozzles
The kit white metal nozzle detail is as good as you could expect. I therefore combined scratch built actuators etc with the F/Path PE fitted inside the kit casings. Rather than trying to paint the jet pipes burnt metal, I burnt the PE with my micro torch.
See photo 18
[9] Panel line re-scribingBy the nature of the process you are not going to get sharp ‘panel’ lines. I therefore opted to re-do all these as well as add thousands (?) of panel screws; not rivets. On a painted aircraft the rivets are not really evident.
See photo

[10] Over-wing Tanks
Overall shape was very good, but again detail ‘soft’ or missing. Weld seams were added, pointed nose ‘flattened’ and panels added/re-scribed. The dots indicate the use of narrow strips of styrene sheet inside to strengthen/thicken the joint (common with fuselage joint).
And finally, here is the ‘whifer’: See
