About this Plan

Me 323 Gigant. Scale model for radio control.

Quote (google-translated): "Messerschmitt Me 323 Gigant. The Story of the creation of a gigantic aircraft model.

About 5 years ago I saw a 3-page view and the aircraft data sheet (FT-56) of a Messerschmitt Me 323 in an issue of FMT from 1959 (episode 42). In an accompanying article it was pointed out that this aircraft could be easily recreated as a model. This thought never left me; It was clear to me that I would fly such a model, namely the version with 4 engines, at some point. Of course, it was also clear to me that this plan could not be realized overnight and that two to three 'pre' models would certainly have to be built before the 323 that I had in mind would be socially acceptable.

So I started with the plan for a glider (type designation Me 321), which would have a remarkable wingspan of 3400 mm. This obviously gave rise to the question of decomposability. I then solved this problem with the help of a split tongue and the steel wires in the outer wings. Split tongue because a continuous tongue is too heavy with a hull width of 16 cm and there must still be room to install the remote control system (see Fig. 1).

In order not to increase the space required, the tongue should not remain on the fuselage during transport. A socket strip with tenons was glued between frames A and B, the tongue received two slots and, after being pushed into the fuselage deck rib, was clamped with two M6 cylinder screws. The nuts are glued to the underside of the strip (Fig. 1). The rudder and elevator were one unit and were fixed and held in place with rubber rings and dowels. For weight reasons, I did without the ten-wheel chassis and only installed 6 unsprung wheels.

Since this model has an incredibly large volume of space, it made sense to provide the bottom of the fuselage with two flaps through which 'everything possible' could be thrown off. The two flaps made of 0.5 mm aluminum, 160 mm long and 50 mm wide, were to be operated with an automatic servo. d. H. be opened and closed again. This required a very complex construction (see illustration), but even the greatest effort turned out to be insufficient.

The construction and testing continued, and the first flight was imminent - the model was not yet painted so that changes could be made more easily. Half the club was there, with good advice and pressure. First, a hand launch - this would require the man with the largest paw. There were 500 g (1) of lead under the front fuselage frame, the center of gravity was correct, but the setting angle?' —With a bit of luck and in no time at all, the apparatus flew. 3500 mm wingspan, 4 kg heavy, the flight goes downhill clumsily and sedately. Slight bending of the wings at the fuselage connecting rib.

So the hand start was fine, but what about the manual start? Several Dural hooks have to be attached to the bottom of the hull, but which ones and which rope can create such a giant? The traditional way of high takeoff is not possible because no hand can hold this torso properly. Ground start-high start, it worked perfectly, but the rope was too weak. Over and over again rope reef. Dural tongues that are 3 mm thick and 120 mm wide are also too weak. When you press lightly, the surfaces bend, creating a more V-shape and the rudder appears much too strong..."

Masterpiece. No less.

My father told me that in 1942-43 he saw the Gigant flying over Rome. In 2012 was found in Sardinian sea a Gigant that had been shot down.

Dear Steve, When I saw the Me Gigant I wrote to Hans Ullrich Fischer, who is the president of our or for short AMD association. He build a Nietzer Me Gigant, 6 engine-version in 5m wingspan. He wrote some interesting details I like to share with you and people interested in the plan. Translated version enclosed, cheers Matthias [...see next comment]

Hello Matthias, Thank you very much for your research and the information about it. Our Klaus Nietzer seems to have grown fond of the Me 323. I know the publication in FMT from 1970. Supposedly there was also a Graupner construction kit back then(?).
Why Klaus drew the model with only four motors instead of six as in the original was probably due to the electric flight situation at the time. But in 2011 he sketched the giant again in the six-engine version at a scale of 1:10 (five meters) and built and presented in the model magazine “Building and Flying”. However, a complete blueprint for the “Gigant” has never been published.
In 2012 I bought his sketches, drawn on transparent paper, which I had to send back to him for 60 euros. As a result, my first Me 323 was created and flown several times in the AMD. For example, when flying to Kottspiel, Havelberg in 2013 with a YouTube video by Christoph Roters. Furthermore in Kaltensundheim, in Bad Neustadt, in Weilmünster, for departure in Schleißheim and in Nördlinger Ries. In addition to some display flies in Jena, in Leipzig-Süd, in Greiz, Dresden and in the Erzgebirge.
Nietzer also built a "Me 321" , M:1:10, (the cargo glider variant without engines) for the "Aeronautics Museum" in Rechlin, where it is also in the exhibition. However, there is a plan of this cargo glider variant that can be obtained for money from the vth publishing house's blueprint offer.
Nette Grüße, Hans Ulrich
Attached are a few impressions from the “Gigant meeting” e.g. 2018 in Nördlingen [pics 004-007].

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
