Have you ever had one of those modelling projects that you get 90% finished and then
decide it is just irretrievably bad?
This started out as one of those projects.
I built AMT's 1/48 scale Havoc when it was first released in 1995. Construction went
quite smoothly with only a few hiccups (see full description below). I had a specific idea
of what I wanted to achieve for the paintjob - a chipped and damaged, faded Olive Drab
with Medium Green splotching. But, for one reason or another, the paint job just would not
come out right. I stripped back the paint and started again with a result no better than
the first attempt. At this point I took the model to Chris Wauchop and told him if he
wanted it, he could have it. He accepted the offer and the model sat collecting dust in
the back of Chris's shop for three years!
A recent article on RAAF Bostons in Quarter Scale Modeller got me fired up again. I
retrieved my model from Chris (yes, I'm an indian giver!), stripped the paint off one last
time and refinished the model. This time I'm fairly happy with the results.
Here is a good case for not throwing kits away if you're unhappy with them the
first time around!
RAAF Bostons operated exclusively with 22 Squadron. They saw front-line action between
November, 1942 and November, 1944. The first Bostons used by the RAAF were DB-7Bs and
Early use of Bostons in New Guinea revealed a fatal flaw. Three aircraft were destroyed
when 20 lb fragmentation bombs exploded prematurely after being released from the
bomb-bay. The discontinuation of these bombs on Boston missions was the simple solution to
this tragic problem.
22 Squadron Bostons at Port Moresby sometimes operated alongside 30 Squadron RAAF
Beaufighters. The role of the Boston was that of a conventional bomber on its first target
run, with additional strafing runs over the target area taking advantage of its heavy
Operations were conducted under the typically appalling conditions encountered in the
South-Western Pacific Theatre. Crews fought malaria, harsh heat, stifling humidity,
tropical thunderstorms and unfriendly wildlife before even leaving the ground. RAAF
Bostons encountered heavy anti-aircraft defences, and the long distances flown over water
and jungle presented real dangers. As if all this was not bad enough, many downed aircrews
were executed - some being beheaded.
conditions were a constant challenge to maintenance personnel, but the Boston proved to be
a reliable workhorse and was popular with its crews.
22 Squadron followed the Allied advance; island-hopping from Moresby to Goodenough
Island, to Kiriwina Island, to Noemfoor and finally to Morotai.
In June 1944, 22 Squadron received replacements for its weary Boston IIIs. The turreted
A-20G added welcome extra bomb-carrying capacity. The added defensive capability afforded
by the Havoc's power-operated Martin turret was academic at this stage of the Pacific war
- air resistance by Japanese forces was almost unheard of.
29 A-20G Havocs (Boston IV) were eventually delivered to 22 Squadron.
The service life of these aircraft was cut prematurely short by a Japanese air-raid on
22 Squadron's base at Morotai Island. This raid destroyed eleven and damaged two A-20s.
This was the end of Boston/Havoc operations for the RAAF. The Squadron was immediately
withdrawn to Noemfoor to be re-equipped with Beaufighters.
22 Squadron Bostons operated alongside USAF Squadrons in New Guinea operating the same
aircraft type. Many Bostons still lie abandoned in the jungles of the South-Wester
Pacific. During the 1980s, an RAAF-sponsored mission recovered two Boston airframes in
excellent condition. Both are in advanced states of restoration. One will remain in
Australia, and one will be returned to New Guinea for their War Memorial.

AMTs A-20 kits are a welcome addition to the growing range of World War Two
aircraft available in 1/48 scale.
The A-20G "Havoc" with its distinctive Martin turret was the first variant
released by AMT. This was closely followed by the A-20B/C Boston , the glass-nosed A-20J
and the P-70 night-fighter variant.
The A-20G "Havoc" is typical of AMTs recent releases. It is a very nice
The outline of the
kit captures the spirit of the Havoc with its skinny fuselage, bulged in the middle for
the Martin turret; the big fin, the rakishly angled horizontal stabilsers; and the near
flat dihedral of the graceful wings. Engraved surface detail is very crisp and restrained.
There are few sinkmarks or visible ejector pin mark and the undercarriage, engines and
cockpit are adequately detailed.
This model represents the most common variant of the A-20G with the six-gun nose and
turret. The earliest production G models had a four-gun nose and no turret.
Options are few, but the canopy may be positioned open (also displaying the life-raft
stowage area), alternate nose armament is supplied, the turret rotates and the guns
elevate (if you like that sort of thing!). Other nice touches include moulded brakelines
on the main gear legs and detailed gear doors. There's even a partial bomb-bay.
The most noticeable shortcomings of this kit are the main wheels. These feature a
rather bizarre and totally fictitious fish-scale tread pattern. They will need to be
replaced with either the True Details or MDC resin items. The keen superdetailer may also
wish to add structural features inside the very large, very empty main gear bays. Apart
from that, AMT has this subject pretty well nailed!
AMT's parts breakdown and construction sequence is admirably simple for this kit.
Construction commences with the cockpit. Although only made up of six parts, the
impression is quite convincing when assembled. Sidewalls have appropriate
three-dimensional detail moulded integrally. Brass-etched harnesses were the only
The Martin turret is similarly simple but effective.
A one-piece wing spar ensures that the correct dihedral is set, and provides welcome
structural strength to the fuselage.
The nose section
was a poor fit. I completed the nose sub-assembly (parts 86,87 and 88) then added the nose
to the assembled mid-fuselage. Lots of filler was needed for the join on both sides of the
fuselage. The other problem is that this nose join is not on a "natural" panel
line. I rescribed a number of panels after the nose was faired in. In retrospect, I
probably should have added each nose half to each fuselage half before assembling
the fuselage. This would leave an easier to manage gap at the top and/or bottom seam.
Whatever sequence you use, don't forget to add plenty of nose weight for the tricycle
More filler was required at the lower wing root joint and around the engine nacelles.
Fitting the bomb-bay doors was also difficult as there are few good locating points for
this long, flexible part. Adding a few tabs of scrap styrene to the inside of the bomb-bay
opening will provide a more secure bond for the bomb-bay doors.
The kit was otherwise built almost from the box. Only a few extra items were employed
for this job. The DF loop was replaced with copper wire, "True Details" resin
weighted wheels were installed, aerial wire was added using invisible mending thread
(monofilament) and brass tube substituted for the kit's plastic gun barrels.
RAAF Boston IV s (A-20Gs) were delivered in standard USAAF Olive Drab, Medium Green and
Neutral Grey colours. RAAF roundels were painted over the US Stars, and the
"bars" were overpainted in a colour with a similar tone to OD. Dull Blue and
White fin flashes were applied to most aircraft. The style and position of Squadron Codes
varied widely. The colour was probably either RAAF Sky Blue, or white. Photographs
indicate that it is likely that both colours were employed on different aircraft during
the same period. RAAF serial numbers were applied in 8" high, Medium Sea Grey
characters. Paint repairs would have been made using standard RAAF colours, creating a
I "pre-shaded" panel lines using Tamiya XF-1 Flat Black acrylic. This
was followed by a coat of Aeromaster Acrylic 1043 Neutral Grey and Gunze H307 Olive
Drab. While the OD was still in the paint-cup, I mixed in a few drops of Gunze H71 Middle
Stone. I used this lightened mix to pick-out a number of random panels. I lightened
the mix further and added a few drops of Tamiya X-21 Flat Base before masking and
spraying the fabric control surfaces.
Gunze H320 was used for the US Medium Green. This colour was also lightened for
the control surfaces. The fin was painted Polly Scale K3/178 Foliage Green, and
more panels were picked out in different shades of brown and Olive Drab. The main paint
job was completed with a very thin coat of black over panel lines.
Decals came from a number of sources. Fuselage roundels and fin flashes were from
Tasman's RAAF Roundels (set 7202). I used Tasman's new "semi-weathered" roundels
(set no. CS4808) for the upper wings. Aussie Decals
supplied the nose art (from Boston set no. A48015) and
the 8" stencil serials (set no. 703). "Just Planes" new Faded Sky Blue
Letters was the source of the squadron code.
Final weathering took place after the decals had set. Panel lines on the lower surface
were highlighted with a sharp 2B pencil, and upper surface panel lines received a thin
wash of Tamiya X-18 Semi-Gloss Black.
Paint damage was added, mainly to the wing
leading edges and the tail surfaces plus wingroot walkways, using tiny spots of Tamiya
XF-16 Flat Aluminium applied with a fine brush.
Wings and engine nacelles were
sprayed with thin streaks of Tamiya XF-57 Buff and X-21 Flat Base to
represent exhaust staining.
Apart from some fit problems around the nose and lower fuselage, the AMT kit was a
straightforward and satisfying project.
This project has reinforced a couple of important principles for me. First, never give
up on a modelling project; and second, even a basic Olive Drab paint job can be made
attractive with careful weathering and unusual markings!
