First flown on 25 June 1919, the F.13 was Junkers' first commercial aircraft and the world's first all-metal transport plane.

Aerodynamically clean and without external bracing, it surely stood out in an essentially biplane era, with only Fokker designs being of comparable modernity.

Typically for Junkers, it used a duralumin structure entirely covered with corrugated and stressed duralumin skin.

The wing structure featured nine circular cross-section duralumin spars with transverse bracing. All control surfaces were horn balanced.

Behind the single engine was a semi-enclosed cockpit for the crew, roofed but without side glazing, whereas the passenger cabin was fully enclosed and heated, with windows and doors in the fuselage sides.

Passenger seats were fitted with seat belts, an unusual feature for the time. The plane used a fixed conventional split landing gear with a rear skid, though some variants used floats or skis.

The type could be fitted with a variety of power plants, including Mercedes, BMW, Junkers and Armstrong Siddeley Puma liquid-cooled inline, but also Gnome-Rhône Jupiter and Pratt & Whitney Hornet air-cooled radials.

To overcome the restrictions imposed by the Inter-Allied Aeronautical Commission of Control, which banned the production of warplanes and of any aircraft in the period of 1921–2, Junkers picked up orders abroad from 1919 onward in Austria, Bolivia, Colombia, England, France, Italy, Japan, Poland, Republic of China, Soviet Union, Turkey and USA, with examples manufactured under license in both the USA and the Soviet Union.

A number of the above countries were also military users of the type.

Junkers set up its own airline to encourage the acquisition of the advanced plane by German airlines which was flying 60 of them by 1923. They also established a branch of this airline in Iran.

In total, 322 planes were manufactured, an exceptionally large number for a commercial airliner of the era and were operated all over the globe. It remained in production for thirteen years and in commercial service for more than thirty, the last of them retiring in Brazil in 1951.

A German-Swiss project to build a reconstruction of the F.13 was launched in 2009 and the first example flew in 2016. The reconstruction is equipped with radio and transponder and uses a 1930s Pratt & Whitney R-985 Wasp Junior engine, but is otherwise very close to the original. Additional reconstructions are to be sold for $2.5 million apiece.

The kit was build as a participant to our little "First and Last" group.

Revell has to be congratulated, not only for coming up with a mainstream representation of this important plane, but also for providing a very good kit, which, in its more recent reissues, sports fresher decals that will conform to the famous corrugated surface with the aid of strong softening solutions.

  1. A neat model of what is an important plane in aviation history, Spiros, good work my friend.

  2. Great build! Very funny Junkers 🙂 It's hard to believe that something with such a non-aerodynamic design could take off 🙂

  3. Great build of a unique aircraft- well done!

  4. Very cool, Spiros (@fiveten). Well done on building a plane with corrugations in the skin. Several air forces used this plane. I have thought about buying this kit several times, but I worried about how the corrugations would impact the construction and the decals. It certainly looks like the ripples weren't a problem for you. Well done.

  5. Very nice! I don't know that I've ever run across this kit (or aircraft, for that matter).

  6. A great build, Spiros @fiveten. Excellent work done on this micro scale aircraft. Strange to see that in that era pilots were still in open air while the passengers travelled quite 'comfortable'.

  7. Nice build and I very much enjoyed the cool history lesson! Thank you.

  8. That is one interesting plane especially the crew’s open cockpit, Spiros @fiveten. Well done. I am unfamiliar with the term “horn balanced” for the control surfaces. What does that mean?

    • Thanks my friend @eb801!

      The horn balance is a section of the control surface at the tip that extends forward of the hinge line. It extends outboard of the tip of the fixed surface the control surface rides on. Here is a horn-balanced elevator...

      Its purpose is to tailor control surface hinge moments as well as the effectiveness of and force required to operate those surfaces.

      There are other types of balances too, each having its advantages and disadvantages

  9. I always enjoy reading the Spiros experience in modeling. This kit proves that there are older kits that still hold there own in contemporary modeling. Can teach a little history and be fun.

    Two thumbs up Spiros.

  10. Nice work Spiros. Thanks for sharing your work the bit of history behind it.

  11. All of the above, my friend, looks great!

  12. Excellent work and fascinating detail on horn balances

  13. Excellent work on this @fiveten. A great result.

  14. Great build and a very interesting plane. Nice job on the overall finish.

  15. Here's a reconstructed F.13 that I saw at Oshkosh this year.

  16. Great work , Spiros. Also, nice write-up on the MM Website.
    I also wasn't sure about the term 'horn balanced' - and now I do.

  17. I’ve learned a lot reading through this, Spiros @fiveten.

    Another brilliant Junkers!

  18. A very interesting aircraft and a fine build, Spiros @fiveten. It must be quite tiny in 1/72. The quality of the detail makes it look 1/48. I have wanted to do its big brother and successor the W.34 as a Canadian Airways bush plane ever since I saw a real one in the Canadian Aviation and Space Museum.

    It's semi-open cockpit (at least in the pic) must have made it pretty cold to fly in that climate. There is a nice kit in 1/48 from Special Hobby. You've given me some inspiration. Thanks.

    • Also in 1/72 from Special Hobby, impressed into RAAF sevice from Guinea Airways in early 1942.

    • Thanks my friend @coling! Looking forward to your W.34!

  19. Nicely built and presented Spiros.

  20. Blink around here and you miss stuff

    Nice work sir. I keep looking at the size of the wings on this...the real one must have been able to take off by itself in a five mile an hour breeze
