Junkers F 13 History for the Revell Kits
Anecdote has it that on Armistice Day November 11, 1918 Professor Hugo
Junkers directed his Chief Designer, Otto Reutter, to switch immediately
from military projects to civil projects. The first result of this directive
was a modification of the J 10, two-place, armed, observation plane, into
the J 12, a light four passenger civil airplane. Only the prototype was
built. The J 12 quickly became the J 13, which was marketed as the F 13,
four-passenger, two crew airliner. The prototype, w/n 531, “Annelise”
made its first flight June 25, 1919 at Dessau in the hands of test pilot
Karl Monz. The German Air Transport Registry gave the second F 13, “Hertha”,
the first post war civil registration, D-1.
On September 13, 1919, Monz took Annelise up to 6, 750 meters with six
passengers aboard, unofficially breaking the altitude record for civil
transports. The feat was “unofficial” because Germany had
been excluded from the Federation Aeronautique Internationale (FAI). F
13s were built, by Junkers, at Dessau and in Limhamm, Sweden; they were
also license built in the USSR, the USA and Japan. Production of F 13s
at Dessau ended in 1932. Altogether something approaching 1000 F 13s were
built but the exact number is unknowable. The simple, rugged, all-metal
F 13 was operated all over the world in all manner of duties on wheels,
skis and floats. Many were in service well into WWII.
The Revell Kits
Revell of Germany first released the F 13 as kit No. 4215 in 1992 on
wheels. This first issue has a significant error in that the fuselage
corrugations, aft of the passenger cabin, run parallel with the fuselage
centerline rather than with the top longeron, as they should. This was
corrected in the 1994 release of kit No. 4213 on floats but with the wheeled
landing gear included. In 2007 the corrected kit was released again, as
kit No. 4249, with floats and wheels. All three releases feature the long
wing with straight ailerons. The short wing with curved ailerons was more
common. Be sure your references support the match-up of the physical configuration
of the airplane and the markings you’ve chosen to use. F 13 configurations
are a minefield for the unwary; they varied mainly in wingspan, ailerons,
fins, rudders, exhausts and propellers.

The biggest problem with this kit is the thick trailing edges of the
wings and tail group. When I do my next one I will carefully sand down
the faying surfaces of the upper and lower wing halves at their trailing
edges. As the Stabilizer/elevator is one solid piece there’s nothing
you can do to thin its trailing edges so I drooped the elevator to hide
the T.E. The rudder is also in one solid piece with the fin. As there’s
no way to hide its T.E., I made a new, separate, rudder from the rudder
of a donor Ju 52/3m. With the usual clarity of hindsight I realize I could
have done the same with the elevator and recommend you do so. The two
later issues of the kit have the fin/rudder for the seaplane molded in
left and right halves, with thin trailing edges so you can steal that
rudder for the earlier kit if you want.

Assembly of the fuselage is a bit fiddly. There is a separate top and
two sides; each side includes half the belly. The cockpit, cabin interior
and engine sub-assemblies are trapped between the sides. The engine can’t
be seen at all so mine went into the spares box and I blanked off the
hole in the engine cover from the inside and later attached the rhino-horn
exhaust to the blanking piece.
The plastic is quite soft making it fairly easy, albeit time consuming,
to clean up the poorly formed corrugations at the turn of the bilges and
the turn of the crown into the sides of the fuselage. The same tedious
cleaning up is required at the leading edge of the wing.
The floats are each in four pieces; two sides, a top and a bottom. This
manner of molding them provides good detail on all four surfaces.
The fit of everything is quite good; I used a very few, very tiny spots
of filler on the leading and trailing edges of the wing. Extra touches
that I added included tied-back curtains at the windows, a scratch-built
cockpit interior, thinned lift/grab handles, new door handles, control
horns and cables all round. The over thick windscreens were replaced with
new appropriately thin pieces.
The 4215 kit decals provide markings for two airplanes as operated by
Deutsche Luft Hansa in the twenties. NOTE: “Luft Hansa” became”
Lufthansa” in 1936.
The 4213 kit decals provide markings for two factory-owned planes used
as sales demonstrators in South America in 1924/26. Both were ultimately
sold to Lloyd Aero Boliviana. The decal sheet does not include the two
ship names “Flamingo” and “Kauz”.
The 4249 kit decals offer a cornucopia of markings delights providing
markings for four different planes: Danziger Luftpost, the Alderhof German
Test Flight Center, OLAG Airline and Ad Astra Airline.
The decals work well but I urge you to cut them all out as close to
the printed image as possible to minimize problems with getting them to
lie down into the corrugations. I also recommend using a strip of low-tack
tape as a guide to keep the registration numbers straight.
Revell Kits Conclusion
These are good kits, of an historically significant airplane, except
for those awful, thick trailing edges. Given the historic significance
of this subject, I think Revell of Germany would do well to retool the
kit and reissue it to a quality that is up to the current state of the
art. They would also do well to issue it with optional outer wing panels
and ailerons.
