Junkers G 24 History for the Revell Kit

The G 23/24, Junkers’ first tri-motor, and the world’s first all-metal tri-motor, entered production in 1924 in Dessau. The first flight was, however, made from Furth, near Nurnberg in October 1924. Flight testing was then moved to Dubendorf, Switzerland as Ad Astra Airline of Switzerland bought four of the planes becoming the first customer for the type. Underpowered G 23s built at Dessau, in accordance with the restrictions imposed on the German aircraft industry by the terms of the Versailles Treaty, were flown to A.B. Flygindustri in Limhamm, Sweden where they were fitted with more powerful engines, re-designated as G 24s, sold and then delivered from Sweden to their operators. All of this was to evade the Allies’ restrictions. G 24s were operated on wheels, floats and skis by, at least, 12 nations between 1924 and 1940. Some were converted to F 24 freighters later in their lives by the installation of a single engine in the nose that was more powerful than the three engines normally used. Some F 24s served well into WWII. The G 24/F 24 evolved directly into the Ju 52 and Ju 52/3m.

Records firmly account for 72, G 23/24s having been built but the matter of a total is confused by Junkers’ issuance of 87 werk nummers (w/n) for the type. It has not, thus far, been determined if any of the 15 numbers unaccounted for were built

The Revell Kit


As with the F 13, thick trailing edges are THE problem with this kit too. This time Revell did a good job on the rudder, elevators and ailerons, which are separate pieces but they went waayyy out of their way to screw up the flaps and the rest of the trailing edge of the wing. Although the wing is in three pieces, two top halves and a full span bottom, the flaps are molded full thickness on the bottom half and are about a scale foot (350mm) thick at the T.E.! This makes reducing the T.E. thickness impossible. You can, however, replace the flaps with new flaps made from the inboard wing T.E. of a donor Ju 52/3m kit. The overly thick T.E. between the flaps and the ailerons is dealt with by extreme sanding of the under side of the upper wing halves in this area and then bending it down a bit to meet the lower half. Heavy sanding of the faying surface of the lower wing half will complete the corrections to the wing’s T.E. and should leave you with a good looking wing – apart, that is, from the fact that it is too long. The Arctic Decals instructions show the changes required to correct the span.

The kit designer got some other details wrong besides the wing. The fuselage is 11/32” (9mm) too long - all at the rear. Using Arctic Decals’ instructions as a guide cut this amount off the fuselage sides forward of the rudderpost. Before attaching the fuselage top sand a taper on its bottom from full depth at the bold lateral panel line aft of the door to naught 1 1/8” (29mm) forward of the rear end so that the crown line of the fuselage tapers down to the L.E. of the stabilizer. You will have to fiddle the fit of the tailplane to the, thus revised, aft fuselage. Two more errors complicate the fuselage. One you can correct easily, the other you might as well forget, as it’s too difficult. To correctly replicate K-SALC you must scribe a door on the right side of the fuselage. Details of shape and location are given in the Arctic Decals drawings. The other error, which I will ignore, is the essentially flat bottom of the fuselage from the wing T.E. to the rudderpost. In actuality, the aft fuselage had a quite rounded bilge.

Now with the fuselage and wings corrected you can address the rudder. As originally delivered, K-SALC, had a stock Junkers tail. Alas Revell got the chord too narrow by ~ 1/16” (~2mm). Again, the Arctic Decals instructions show the corrections required. I think I’ll fix this by adding a 1/16” strip to the L.E. and filling, filing and sanding it to blend in.

Not much of the passenger cabin interior will be visible so I’d suggest you forget about detailing it. Add tied back curtains at the windows to make viewing the interior even more difficult and you can reduce the amount of work you must do. The kit cockpit is adequate unless you are seriously afflicted with AMS.

The kit decals are relevant to K-SALC only as it was upon delivery to Aero O/Y and err in having the markings applied to the black painted areas of the airplane in white rather than in silver as on the original. The kit’s painting instructions also err in several details, the correct form of which is provided in the Arctic Decals instructions.


This is a difficult but buildable kit if you are dedicated to the task. Built out-of-the-box with the kit decals it will look broadly like a G 24 but will feature myriad errors. Follow the suggestions above and the suggestions packed with the Arctic Decals and you can build a superb model of the G 24. I bought two of these from Emil Minerich’s Skyway Model Shop in Seattle in 1991 but have forgotten the price.
