From the archive (2010):
The General Aviation PJ-1 (AF-15) twin pusher flying boat
design combines the uncommon with the visually pleasant. Five planes of this
type were built and all went into service with the Coast Guard starting in 1932
as FLB (Flying Life Boats). All had names of stars starting with the letter “A”
(Antares, Acrux, Acamar, Arcturus, Altair). So you have some variations on schemes
and details to pick from. One was converted to a tractor version and
re-designated PJ-2. It had P&Ws of slightly more power, a different canopy
and of course a different engine pylon and gondola arrangement. Some of these
planes had “finlets” on the stab. One machine at certain point had three-blade
props, and another had the annular Townend rings way ahead of the engine.
Another had a sort of small wing in a low position after the engines. Still
another (or perhaps the same) had a small wing above the leading edge. No doubt
there was some experimentation going on there.
The General Aviation PJ-1 was specifically designed and made
for the US Coast Guard. The very tangled corporate web that gave birth to this
plane includes General Motors, Fokker (the wing was of Fokker design and there
is more than a passing resemblance with the Fokker F-11), North American and
Douglas. Another child born of this multiple parents is the Clark -General
Aviation- GA-43 –of which an article was posted here:
The JP-1 had a retractable beaching gear, but it couldn’t be
used as a landing gear. The pusher configuration was of course chosen to keep
the props and carbs out of the spray.
They were successful in their mission and saved many lives.
The Execuform vacuformed kit of the PJ-1 is made of sturdy
plastic. The parts were removed from their backing sheet and as in any other
vacuformed kit you have to refine those parts later on, to make for a good fit
and proper thinness on trailing edges. So some careful sanding is involved, whilst
frequently testing the parts to be sure you are on track.
This is a relatively big kit and it will require that you
scratchbuild the interior, engrave some panel lines and the separation lines of
the control surfaces. Some clear plastic is provided for you to make the
windows, which are all flat. Engines, propellers, wheels, struts and some minor
external details (like the loop antenna or the landing lights) are all to be supplied
by the modeler. Same for the decals. The kit provides good documentation and annotated
1/72 plans to accomplish all that.
I would like to remind again fellow modelers that the
existence of this type of kits it’s a bliss, even if they are basic, since no
mainstream manufacturers is likely to produce kits of esoteric planes. Yes, you
have to get some extra parts and work a little, all the better, that’s what it
makes a model “yours”; you put something of you in it, and you learn and hone
those skills. These kits are a starting point and they are not meant to compete
with mainstream ones, they just pick-up the trail where the big guys left it,
so we can have interesting models of less-known types. For me and many others
that’s great and worth the extra effort.
US Coast Guard V113 livery was chosen, mainly because of the
difficulty of printing white decals for the other (blue background) livery
options (I do not have an ALPS nor I want to buy one); besides I found on the
Net several pics of this particular machine. It has a less showy color scheme
but overall presents a cleaner visual effect. Different wing float strut
arrangements can be seen in photos during its life. Study your chosen subject
and compare any plans or drawings you may have with actual photos.
I decided to replace some flying surfaces and other details.
Since the tail group was made of metal tube and fabric-covered, I scratched it
from sheet styrene. The ailerons were corrugated metal (while the whole wing
was wood) so I cut them out and replaced them with parts made from corrugated
styrene sheet. Have in hand some Evergreen or Plastruct rod sections, since you
will have to add the strakes that are visible on the fuselage sides and bottom
and the area surrounding the engine pylons. No cockpit or interior data is
provided with the kit nor could any specific info on the matter be found
elsewhere, so a generic cockpit was depicted. The windows were made with the
clear plastic provided with the kit, which resulted to be excellent, whatever
material that is. It cut cleanly and sanded well. The step on the hull was
refined and strakes (26 of them) were measured, cut, touched-up and glued to
the bottom and sides. I encountered a not good merging of the wing “back” with
the fuselage and found that the wing fillets needed to be corrected –I had to remove
the originals-, so the area was reinforced with more styrene from inside and
re-contoured.
Brass “Strutz” were used for the necessary parts. MV lenses
were utilized for the landing lights, and navigation lights came from the generic
CMR set. Additional details –to name just a few- were loop antenna, Pitot tube,
beaching gear cables and pulley anchor, rigging, wire antenna, rudder “paddles”,
control horns and cables and mooring bits, the latter were part of a resin set
sold by Khee-Kha Art Products for one of its bush panes.
I diverged from Execuform’s recommendations regarding the
type of yellow color on the plane’s scheme and some of the lettering fonts.
You may see an upper wing walkway among the decals on the
“in progress” images. That didn’t work. I had to mask that area and paint it
almost at the very end. Retrospectively it would have been better to prepare
the area where the pylons are glued and leave them out until after completion
of painting. I could have done that because I worked out a good wing/pylon
joint, but got carried away and glued them without a second thought.
Do not forget those servo tabs on the rudder.
The captioned photos will give you an idea of the steps,
procedures and materials. If they don’t, you could always take up teratology or
quilting. There is always hope where there is a will.
Bonus track:
Scale Modeling
Scale modeling is a rigorous discipline created at the
Shaolin Temple in the beginning of time in order to hone both, spirit and
flesh.
Through its practice the apprentices (usually called
grasshoppers, but also monkey-head, cork-brain, flan-hand and worse) developed
the necessary skills to become perfect lunatics, socially-inept,
obsessive-compulsive outcasts.
SO fine, "Gabriel"; I just gotta get one of these for the Coast Guard collection here!
