ROSEPLANE 1/72 Vacform
Oeffag C.II Series 52.5
Kit # 208
A Brief History
Oeffag signed a production contract on 8 February 1916 to supply 32
C.II reconnaissance biplanes to replace the C.I and the older Aviatik
types. Although the Oeffag C.II represented a considerable design refinement
over the C.I, its performance and maneuverability were below expectations.
The C.II series 52 aircraft were dispatched to the Russian Front to serve
singly with Fliks 3, 5, 13, 14, 18, 20, 22, 25, 27 and 30. They were used
mainly for close reconnaissance and radio spotting.
A second batch of 32 C.II biplanes was ordered on 4 December 1916, known
as the "lightened series 52." Designed for the 185hp Daimler engine, most
flew with the 160hp engine.
Structurally, the C.II was designed for efficient production and ease
of rigging. But the type was roundly criticized as being too narrow, having
sluggish controls and unsuitable for combat. The C.II was retired from
combat in 1917 and served as an advanced trainer.
The kit consists of two sheets of instructions and history, one sheet
of vacuformed parts and ten resin parts. There are no decals supplied
with the kits. This is another model of a very obscure airplane. The kit
is a basic vacuform, but of the high quality that one has come to expect

Before construction can begin on this kit, you must obtain the information
found in "Austro-Hungarian Army Aircraft of World War One - Flying
Machines Press 1993". This reference material will provide the much
needed photos to build this model successfully.
Construction begins with cutting all of the vacuformed parts from the
sheet. Using 80 grit wet/dry sandpaper, the parts are carefully sanded
to the proper shape. The upper wing has a center section cutout that can
be hidden with the resin fuel tank. But I decided to cut this section
out. It is clearly marked on the wing and with care should not present
any problems. The plastic is of sufficient thickness for a single thickness
wing. After obtaining the proper shape and thickness, the bottom of the
wing was scribed with a scribing to represent the ribs. The ailerons were
also scribed. I then painted and decaled the wings.
There is no information on the interior of this plane but using other
Austrian two-seaters as a guide, an interior was built. The Austrians
liked the single cockpit arrangement and several photos of other Austrian
planes gives enough information to build the interior of this plane. After
the interior is complete and the engine mounted, the fuselage is closed
up, sanded and painted.
Next, the lower wings and the tail planes are mounted. The lower wing
is located and attached using Testor's liquid glue. A bead of super glue
is used to strengthen this joint. The rear of the fuselage is notched
to accept the horizonal stabilizer. The bottom of the rudder has to be
shortened to match the bottom of the fuselage. It is just a touch too
The most difficult part of this model is the mounting of the top wing.
The struts slant inward and the alignment is critical. Before mounting
the landing gear, align the top wing upside down next to the lower wing.
Mark the lower wing strut positions and then mark the upper wing positions,
allowing for the slant of the struts. Check and recheck this arrangement
as this will create major problems when the wing is being attached. I
mounted the struts in the lower wing using liquid glue. Before
these dried completely, the upper wing was mounted with the same liquid
glue. Then mounting the plane on a piece of balsa wood, large straight
pins were used to set the alignment. The cabanes are added while still
in the jig. The cabanes gives the upper wing its final alignment and strength.
The landing gear is constructed and mounted and a tailskid made from
sheet plastic. The radiator is mounted on the cabanes and exhausts are
added. I replaced the above wing fuel tank with a gun housing. Where the
fuel tank goes when this is done is unknown. It does not show on any of
the photos in my possession. The machine gun ring is constructed and the
gun is attached. This unit is then positioned on the model. The model
is then rigged using DURAS method and it is complete.
The CDL is custom mixed; the dark wood is Testor's Wood with some red
added and the wood grain is Testor's wood
applied with a 10/0 long bristled brush. The decals are by AMERICAL.
This model depicts an aircraft from Flik 13, Sept 1917. It is shown
with the fuselage crosses and white fields in eight positions. The crews
complained that the fuselage crosses provided a good aiming point, hence
they quite often removed thembefore the official decree of April 1916.
Start to finish took about 20 hours. With proper advanced planning on
the top wing, you can avoid the grief of trying to attach the top wing
more that once. This is an attractive kit when completed and represents
nicely a very obscure aircraft.
